DELETE ALL ROWS Parameter
This parameter specifies that all rows in the target base table are to be deleted. Valid values are true and false (the default). Existing values in the EIM table and delete matches expressions are ignored.
This parameter will only write the user keys values of the deleted target table rows to the EIM table columns. It will not write values of nonuser keys columns or nontarget table rows column values to the EIM table. The deleted rows cannot be reimported using the EIM table rows written by the EIM delete process, because they will not contain all the original information.
Caution: Use the DELETE ALL ROWS = TRUE setting with extreme
caution. It will delete all rows in the named base table including
any seed data. Do not remove unnecessary seed data by deleting all
rows from the S_LST_OF_VAL base table. If you do so, you will not
be able to reimport “clean” data and you will be forced to rebuild
the seed data or restore from backup. To selectively delete rows,
use the DELETE EXACT or DELETE MATCHES expressions.
