Import delimited file oracle

Most of the examples use the sample schemas of the seed database, which is installed by default when you install Oracle Database. In particular, the human resources hr schema is often used. Examples that specify a dump file to import assume that the dump file exists. Wherever possible, the examples use dump files that are generated when you run the Export examples.

The examples assume that the hr user has been granted these roles. If necessary, ask your DBA for help in creating these directory objects and assigning the necessary privileges and roles. Oracle Database Sample Schemas. Your Oracle operating system-specific documentation for information about how special and reserved characters are handled on your system. Stopping the job enables the Data Pump control job table to be queried before any data is imported. Stops the job after it is initialized.

Syntax and Description. The possible values correspond to a process order number in the Data Pump control job table. The result of using each number is as follows:. The job is stopped at the object that is stored in the Data Pump control job table with the corresponding process order number. If the data for a table cannot be loaded with the specified access method, then the data displays an error for the table and continues with the next work item. Data Pump determines the best way to load data for each table.

Every time it reads a row, Data Pump executes an insert statement that loads that row into the target table. This method takes a long time to load data, but it is the only way to load data that cannot be loaded by direct path and external tables.

This option is available only for network mode imports. This command attaches the client session to an existing import job, and automatically places you in interactive-command mode. If the job you are attaching to is stopped, then you must supply the job name. When you are attached to the job, Import displays a description of the job, and then displays the Import prompt.

To force Data Pump Import to use only the instance where the job is started and to replicate pre-Oracle Database 11g Release 2 This example performs a schema-mode import of the hr schema.

Up to 3 parallel processes can be used. Note that there is no dump file generated, because this is a network import. ALL : loads any data and metadata contained in the source.

This is the default. It does not load table row data. You can create the expfull. This command runs a full import that loads only the metadata in the expfull. It runs a full import, because a full import is the default for file-based imports in which no import mode is specified. Specifies the credential object name owned by the database user that Import uses to process files in the dump file set imported into cloud storage.

The import operation reads and processes files in the dump file set stored in the cloud the same as files stored on local file systems. Substitution variables are only allowed in the filename portion of the URI.

Instead, the strings are treated as URI strings. Oracle Data Pump validates if the credential exists, and if the user has access to read the credential. Any errors are returned back to the impdp client. You can create the dump files used in this example by running the example provided for the Export DUMPFILE parameter, and then uploading the dump files into your cloud storage.

The import job looks in the specified cloud storage for the dump files. Example: Specifying a User-Defined Credential. The following example creates a new user-defined credential in the Oracle Autonomous Database, and uses the same credential in an impdp command:. There is no default.

If this parameter is not used, then the special data handling options it provides simply do not take effect. The default behavior is to import each table partition as a separate operation. Import chooses the default. For instance, when this partition is set, and there is a possibility that a table could move to a different partition as part of loading a table as part of the import, Oracle Data Pump groups table data in one partition.

Oracle Data Pump also groups all partitions of a table as one operation for tables that are created by the Import operation. Deferred constraint violations always cause the entire load to be rolled back.

It logs any rows that cause non-deferred constraint violations, but does not stop the load for the data object experiencing the violation. Use this option when you are using Oracle Data Pump to create the table from the definition in the export database before the table data import is started.

Typically, you use this parameter as part of a migration when the metadata is static, and you can move it before the databases are taken off line to migrate the data. Moving the metadata separately minimizes downtime. If you use this option, and if other attributes of the database are the same for example, character set , then the data from the export database goes to the same partitions in the import database. You can create the table outside of the data pump.

However, if you create tables as a separate option from using Oracle Data Pump, then the partition attributes and partition names must be identical to the export database. If the import encounters invalid data, then an ORA error is written to the. The error text includes the column name. The default is to do no validation. Use this option if the source of the Oracle Data Pump dump file is not trusted.

This option is useful if the network connection between the remote and local database is slow, because it reduces the amount of data sent over the network. Stream format errors typically are the result of corrupt dump files. If Oracle Data Pump skips over data, then not all data from the source database is imported, which potentially skips hundreds or thousands of rows.

If any non-deferred constraint violations are encountered during this import operation, then they are logged. The import continues on to completion. Specifies the default location in which the import job can find the dump file set and where it should create log and SQL files. It is not the file path of an actual directory. You must have Read access to the directory used for the dump file set. You must have Write access to the directory used to create the log and SQL files.

This command results in the import job looking for the expfull. Specifies the names, and, if you choose, the directory objects or default credential of the dump file set that was created by Export. If you do supply a value, then it must be a directory object that already exists, and to which you have access. The Import process checks each file that matches the template to locate all files that are part of the dump file set, until no match is found.

Sufficient information is contained within the files for Import to locate the entire set, provided that the file specifications defined in the DUMPFILE parameter encompass the entire set. The files are not required to have the same names, locations, or order used at export time.

In addition, the substitution variable is expanded in the resulting file names into a 3-digit to digit, variable-width, incrementing integers starting at and ending at The width field is determined by the number of digits in the integer. The 3-digit increments continue up until Then, the next file names substitute a 4-digit increment.

The substitutions continue up to the largest number substitution allowed, which is Only one form can be used in the same command line. This example specifies the default location in which the import job can find the dump file set, and create log and SQL files, and specifies the credential object name owned by the database user that Import uses to process files in the dump file set that were previously imported into cloud storage.

Some Oracle roles require authorization. This prevents unauthorized access to an encrypted dump file set. Specifies a password for accessing encrypted column data in the dump file set. This parameter is also required for the transport of keys associated with encrypted tablespaces, and tables with encrypted columns during a full transportable export or import operation.

The password that you enter is echoed to the screen. This parameter is required on an import operation if an encryption password was specified on the export operation. The password that is specified must be the same one that was specified on the export operation. This parameter is valid only in the Enterprise Edition of Oracle Database 11g or later. Data Pump encryption features require that you have the Oracle Advanced Security option enabled. Encryption attributes for all columns must match between the exported table definition and the target table.

Both of the following situations would result in an error because the encryption attribute for the EMP column in the source table would not match the encryption attribute for the EMP column in the target table:.

In the following example, the encryption password, , must be specified, because it was specified when the dpcd2be1.

The advantage to setting the parameter to YES is that the encryption password is not echoed to the screen when it is entered at the prompt. If you specify an encryption password on the export operation, then you must also supply it on the import operation. The following example shows Oracle Data Pump first prompting for the user password, and then for the encryption password.

Instructs the source system in a network import operation to estimate how much data is generated during the import. BLOCKS : The estimate is calculated by multiplying the number of database blocks used by the source objects times the appropriate block sizes. For this method to be as accurate as possible, all tables should have been analyzed recently. You can use the estimate that is generated to determine a percentage of the import job that is completed throughout the import.

When the import source is a dump file set, the amount of data to be loaded is already known, so the percentage complete is automatically calculated. When the job begins, an estimate for the job is calculated based on table statistics. Enables you to filter the metadata that is imported by specifying objects and object types to exclude from the import job. For the given mode of import, all object types contained within the source and their dependents are included, except those specified in an EXCLUDE statement.

If an object is excluded, then all of its dependent objects are also excluded. For example, excluding a table will also exclude all indexes and triggers on the table. It allows fine-grained selection of specific objects within an object type.

It is a SQL expression used as a filter on the object names of the type. It consists of a SQL operator and the values against which the object names of the specified type are to be compared. It must be separated from the object type with a colon and enclosed in double quotation marks, because single quotation marks are required to delimit the name strings.

Depending on your operating system, the use of quotation marks when you specify a value for this parameter may also require that you use escape characters. Oracle recommends that you place this parameter in a parameter file, which can reduce the number of escape characters that might otherwise be needed on the command line.

Excluding Constraints. Excluding Grants and Users. To exclude a specific user and all objects of that user, specify a command such as the following, where hr is the schema name of the user you want to exclude. Note that in this example, the FULL import mode is specified. Assume the following is in a parameter file, exclude. To run the example, you must first create this file. All data from the expfull. Starting with Oracle Database 12c Release 2 See the following restrictions for more information about using big SCNs.

The import operation is performed with data that is consistent up to this SCN. The import operation will be performed with data that is consistent with the SCN that most closely matches the specified time. The XDB repository is not moved in a full database export and import operation. User created XML schemas are moved. If the target is Oracle Database 12c Release 1 The following is an example of using the FULL parameter. This example imports everything from the expfull. The directory objects can be different, as shown in this example.

Enables you to filter the metadata that is imported by specifying objects and object types for the current import mode. See "Metadata Filters" for an example of how to perform such a query. It enables you to perform fine-grained selection of specific objects within an object type.

It consists of a SQL operator, and the values against which the object names of the specified type are to be compared. It must be separated from the object type with a colon, and enclosed in double quotation marks.

You must use double quotation marks, because single quotation marks are required to delimit the name strings. Depending on your operating system, when you specify a value for this parameter with the use of quotation marks, you can also be required to use escape characters. Oracle recommends that you place this parameter in a parameter file, which can reduce the number of escape characters that you otherwise must use in the command line..

The Import operation will load only functions, procedures, and packages from the hr schema and indexes whose names start with EMP. The bytes must represent printable characters and spaces. If the string includes spaces, then the name must be enclosed in single quotation marks for example, 'Thursday Import'.

The job name is implicitly qualified by the schema of the user performing the import operation. The job name is used as the name of the Data Pump control import job table, which controls the export job. Indicates whether the Data Pump control job table should be deleted or retained at the end of an Oracle Data Pump job that completes successfully. The Data Pump control job table is automatically retained for jobs that do not complete successfully.

The default behavior is to create import. All messages regarding work in progress, work completed, and errors encountered are written to the log file. As with the dump file set, the log file is relative to the server, and not the client. Oracle Data Pump Import writes the log file using the database character set.

That is, the log file must be written to a disk file, and not written into the Oracle ASM storage. However, this prevents the writing of the log file. Specifies that you want to have messages displayed with timestamps during import.. You can use the timestamps to figure out the elapsed time between different phases of a Data Pump operation. Such information can be helpful in diagnosing performance problems and estimating the timing of future similar operations.

The following example records timestamps for all status and log file messages that are displayed during the import operation:. Indicates whether to import just the Data Pump control job table and then stop the job so that the contents of the Data Pump control job table can be examined. Indicates whether additional information about the job should be reported to the Oracle Data Pump log file. Enables an import from a source database identified by a valid database link.

The data from the source database instance is written directly back to the connected database instance. There are no dump files involved. When you perform a network import using the transportable method, you must copy the source data files to the target database before you start the import.

If the source database is read-only, then the connected user must have a locally managed tablespace assigned as the default temporary tablespace on the source database.

Otherwise, the job will fail. The following types of database links are supported for use with Oracle Data Pump Import:. If an import operation is performed over an unencrypted network link, then all data is imported as clear text even if it is encrypted in the database.

See Oracle Database Security Guide for more information about network security. The following types of database links are not supported for use with Oracle Data Pump Import:.

When operating across a network link, Data Pump requires that the source and target databases differ by no more than two versions. For example, if one database is Oracle Database 12c, then the other database must be 12c, 11g, or 10g. Note that Oracle Data Pump checks only the major version number for example, 10g, 11g, 12c , not specific release numbers for example, When transporting a database over the network using full transportable import, auditing cannot be enabled for tables stored in an administrative tablespace such as SYSTEM and SYSAUX if the audit trail information itself is stored in a user-defined tablespace.

This example results in an import of the employees table excluding constraints from the source database. This command results in a full mode import the default for file-based imports of the expfull. Specifies the maximum number of worker processes of active execution operating on behalf of the Data Pump control import job. The value that you specify for integer specifies the maximum number of processes of active execution operating on behalf of the import job. This parameter enables you to make trade-offs between resource consumption and elapsed time.

A nonpartitioned table, scott. A partitioned table, scott. A subpartitioned table, scott. No parallel query PQ worker processes are assigned because network mode import does not use parallel query PQ worker processes. Therefore, the directory object can point to local storage for that instance. Therefore, the directory object must point to shared storage that is accessible by all Oracle RAC cluster member nodes.

A parameter file allows you to specify Data Pump parameters within a file, and then that file can be specified on the command line instead of entering all the individual commands. This can be useful if you use the same parameter combination many times. The use of parameter files is also highly recommended if you are using parameters whose values require the use of quotation marks. A directory object is not specified for the parameter file because unlike dump files, log files, and SQL files which are created and written by the server, the parameter file is opened and read by the impdp client.

The default location of the parameter file is the user's current directory. Within a parameter file, a comma is implicit at every newline character so you do not have to enter commas at the end of each line. As a result of the command, the tables named countries , locations , and regions are imported from the dump file set that is created when you run the example for the Export DUMPFILE parameter.

The import job looks for the exp1. It looks for any dump files of the form exp2 nn. Otherwise, the default is none. A value of NONE creates tables as they existed on the system from which the export operation was performed. The default name of the new table is the concatenation of the table and partition name, or the table and subpartition name, as appropriate.

If a partitioned table is imported into an existing partitioned table, then Data Pump only processes one partition or subpartition at a time, regardless of any value specified with the PARALLEL parameter.

If the table into which you are importing does not already exist, and Data Pump has to create it, then the import runs in parallel up to the parallelism specified on the PARALLEL parameter when the import is started.

You use departitioning to create and populate tables that are based on the source tables partitions. This error message is included in the log file if any tables are affected by this restriction: ORA Dependent objects of partitioned tables will not be imported.

If this event occurs, then the error is reported in the log file: ORA Domain indexes of partitioned tables will not be imported. If there are any grants on objects being departitioned, then an error message is generated, and the objects are not loaded.

The following example assumes that the sh. It uses the merge option to merge all the partitions in sh. However, it can be any SQL clause. If a schema and table name are not supplied, then the query is applied to and must be valid for all tables in the source dump file set or database.

A table-specific query overrides a query applied to all tables. When you want to apply the query to a specific table, you must separate the table name from the query cause with a colon :. You can specify more than one table-specific query , but only one query can be specified per table. Otherwise, Data Pump assumes that the object is on the local target node; if it is not, then an error is returned and the import of the table from the remote source system fails. If you use the QUERY parameter , then the external tables method rather than the direct path method is used for data access.

To specify a schema other than your own in a table-specific query, you must be granted access to that specific table. If the QUERY parameter includes references to another table with columns whose names match the table being loaded, and if those columns are used in the query, then you must use a table alias to distinguish between columns in the table being loaded, and columns in the SELECT statement with the same name.

For example, suppose you are importing a subset of the sh. The maximum length allowed for a QUERY string is bytes, including quotation marks, which means that the actual maximum length allowed is bytes. All tables in expfull. A common use is to regenerate primary keys to avoid conflict when importing a table into a pre-existing table on the target database.

You can specify a remap function that takes as a source the value of the designated column from either the dump file or a remote database. The remap function then returns a remapped value that replaces the original value in the target database. The same function can be applied to multiple columns being dumped.

This function is useful when you want to guarantee consistency in remapping both the child and parent column in a referential constraint. By default, this schema is the schema of the user doing the import. As a default, this is the schema of the user doing the import.

The data types and sizes of the source argument and the returned value must both match the data type and size of the designated column in the table. Remapping data files is useful when you move databases between platforms that have different file naming conventions. Oracle recommends that you enclose data file names in quotation marks to eliminate ambiguity on platforms for which a colon is a valid file specification character. Depending on your operating system, escape characters can be required if you use quotation marks when you specify a value for this parameter.

Oracle recommends that you place this parameter in a parameter file, which can reduce the number of escape characters that you otherwise would require on the command line. Suppose you had a parameter file, payroll. Remapping a directory is useful when you move databases between platforms that have different directory file naming conventions. This provides an easy way to remap multiple data files in a directory when you only want to change the directory file specification while preserving the original data file names.

In addition, Oracle recommends that the directory be properly terminated with the directory file terminator for the respective source and target platform. Oracle recommends that you enclose the directory names in quotation marks to eliminate ambiguity on platforms for which a colon is a valid directory file specification character.

In addition, you have a parameter file, payroll. However, different source schemas can map to the same target schema. The mapping can be incomplete; see the Restrictions section in this topic.

For example, the following Export commands create dump file sets with the necessary metadata to create a schema, because the user SYSTEM has the necessary privileges:. If your dump file set does not contain the metadata necessary to create a schema, or if you do not have privileges, then the target schema must be created before the import operation is performed.

You must have the target schema created before the import, because the unprivileged dump files do not contain the necessary information for the import to create the schema automatically. For Oracle Database releases earlier than Oracle Database 11g, if the import operation does create the schema, then after the import is complete, you must assign it a valid password to connect to it.

You can then use the following SQL statement to assign the password; note that you require privileges:. Unprivileged users can perform schema remaps only if their schema is the target schema of the remap. Privileged users can perform unrestricted schema remaps. The mapping can be incomplete, because there are certain schema references that Import is not capable of finding. For example, Import does not find schema references embedded within the body of definitions of types, views, procedures, and packages.

If any table in the schema being remapped contains user-defined object types, and that table changes between the time it is exported and the time you attempt to import it, then the import of that table fails. However, the import operation itself continues. By default, if schema objects on the source database have object identifiers OIDs , then they are imported to the target database with those same OIDs.

If an object is imported back into the same database from which it was exported, but into a different schema, then the OID of the new imported object is the same as that of the existing object and the import fails.

You can connect to the scott schema after the import by using the existing password without resetting it. If user scott does not exist before you execute the import operation, then Import automatically creates it with an unusable password.

This action is possible because the dump file, hr. However, you cannot connect to scott on completion of the import, unless you reset the password for scott on the target database after the import completes.

Usage Notes. B:C , then Import assumes that A is a schema name, B is the old table name, and C is the new table name. To use the first syntax to rename a partition that is being promoted to a nonpartitioned table, you must specify a schema name.

To use the second syntax to rename a partition being promoted to a nonpartitioned table, you qualify it with the old table name. No schema name is required. Data Pump does not have enough information for any dependent tables created internally. Only objects created by the Import are remapped.

In particular, pre-existing tables are not remapped. Or if video is more your thing, check out Connor's latest video and Chris's latest video from their Youtube channels.

You Asked Hi tom I have a data in the text file delimited by : I want to import the same into a table can i do that by writing a stored proc. Awaiting for your reply Regards Raj.

I know it is against your principle to ask question through this channel but i can't catch you at the specified time since am not connected to net all times.

Please this the question: Hello Tom, My question is that I have 3 tables, 2 of which contain many records. I have to write a code plsql that will select all matching records and insert them into the 3rd table C. The real problem is that table C must contain records in either Excel or Access file format which is saved on a diskette. Thus apart from selecting records from table B to be inserted into table C, I should also find a way of reading or selecting matching records saved on the floppy diskette.

Can this be achievable in oracle7. Can you give me a simple code to do that? Table A studnumber,subject,level Table B studnumber,dept,year Table C studnumber,subject,level,dept,year. Thanks a lot.
