Not sure whether you are using Oracle or not, but from the syntax, it seems that my assumption is right.

You can use the SET AUTOCOMMIT command to help you to issue commit on a preset number of DMLs executed.

SET AUTOCOMMIT ON
Turns autocommit on.

SET AUTOCOMMIT OFF
Turns autocommit off (the default).

SET AUTOCOMMIT n
Commits changes after n SQL DML commands.

SET AUTOCOMMIT IMMEDIATE
Turns autocommit on.

Hope this can help to to solve the problem.

Regards,
Kenneth

To commit after every 50 iterations through your loop, you can use your numcount variable like this:

if numcount / 50 = floor (rowcount / 50) then
commit;
end if;

Oracle publish a random package on their MetaLink website. Try this URL: http://metalink.oracle.com/metalink/plsql/ml2_documents.showDocument?p_database_id=NOT&p_id=1028249.6, or go to MetaLink and search for "random package".
