Why not have the flag in the Login table?

In MySQL you should be able to set a 'trigger' on the insert operation on the login table, that can do the second insert for you. See:

http://dev.mysql.com/doc/refman/5.0/en/triggers.html

You might want to handle deletes and/or updates (change of username?) in the same way.

Meder's answer above will certainly work but prehaps the strategy you are looking for involves triggers; this will allow you to automatically update other info when ever row on a specific table is inserted, updated or deleted.

You only have to create trigger once and then any insert from any source to your LOGIN tbale will also update your CALCULATE table.

My SQL Documentation details the statement here.
