With this SAP DB Loader command, you can control the unloading of database tables.

<tableextract_statement> ::=
TABLEEXTRACT <part_spec> [<configurationstream_spec>] <dataoutstream_spec> [<packagestream_spec>] [<restart>]

You can also use the keywords EXTRACT DATA instead of the keyword DATAEXTRACT.

When you use TABLEEXTRACT TABLE, the source table must exist in the database instance.
THE command TABLEEXTRACT ALL can only be executed by the SYSDBA user.

• You can unload the application data (including LONG values) of the specified database tables in data streams. The format of the data stream must be PAGES in each case.
• You can unload the application data application data (including LONG values) and the database catalog definitions of the specified database tables to data streams. The format of the data stream must be RECORDS in each case.

• TABLEEXTRACT ALL
  The data stream <dataoutstream_spec> contains the application data of all tables.
• TABLEEXTRACT USER
  The data stream <dataoutstream_spec> contains the application data of the tables that belong to the specified user.
• TABLEEXTRACT TABLE
  The specified table is a base table. The user is the owner of this table.
  The data stream <dataoutstream_spec> contains the application data of the specified table.

The data streams <dataoutstream_spec> are created during unloading.

When it processes the commands TABLEEXTRACT ALL and TABLEEXTRACT USER, the SAP DB Loader creates one or more data streams (depending on the size of the tables it is unloading), each of which can contain the application data from one or more tables. The SAP DB Loader specifies the maximum size of a single data stream as 1 GB.

The media names for the data streams are created using the name specified in the command, in that a four digit extension of the format 0001 is added to the name. The maximum number of media for each TABLEEXTRACT is therefore set at 9999.

The system table TRANSFORMATIONMODEL and other system tables are filled.

• Unless you specify the data stream <configurationstream_spec>, all specified tables are unloaded.
• By specifying a data stream <configurationstream_spec>, you can exclude the application data of individual selected tables from the unload process. The tables must be specified in the data stream by the specification of their owner and the table name.
  The information about which tables were not unloaded is stored in the system tables. You can display these tables by displaying the system table TRANSFORMATIONPACKAGES. The tables excluded from the unload of the application data have the value TRUE in the column EXCLUDE.

• The system tables are not unloaded unless you specify <packagestream_spec>.
• By specifying a data stream <packagestream_spec>, all entries of the table TRANSFORMATIONMODEL are unloaded to this data stream.

The specified tables are unloaded to the data streams <dataoutstream_spec>.

If necessary, all entries of the table TRANSFORMATIONMODEL are unloaded in the data stream <packagestream_spec>.

You can reload the tables using the corresponding TABLELOAD command.

The unload process cannot be successfully completed. In this case, the SAP DB Loader logs the cause of the error in the log file.
