With this Loader command, you can control the update of individual column values in tables.
<dataupdate_statement>
::=
DATAUPDATE TABLE <table_spec
> <acc_column_spec_mlt
> <set_column_spec_mlt
> <instream_spec
> [<longfile_spec_mlt
>]
You can also use the keywords UPDATE DATA instead of the keyword DATAUPDATE.
The target table exists on the database instance.
The Loader generates an internal UPDATE statement from the DATAUPDATE command and then executes it.
The individual line values in the specified table columns are updated. All the changes made to the target table(s) as a result have also been written to the log area of the database instance.
If errors occur while a DATAUPDATE command is being executed, the Loader terminates the process and displays an error message. A log file is written.
