Subj:   Writing to tables thru views
From:   william.gregg

Two items:

1) It is my understanding that restrictions on table updates thru views block views built from joins, derived data, or column functions (e.g. SUM, COUNT, CSUM) from performing the ins/upd/del action.

Has anyone found a way around this?

2) Adding the WITH CHECK OPTION enforces constraints thru the WHERE clause (otherwise the WHERE clause is ignored.)

I recall that the WITH CHECK OPTION clause was not working correctly. Is this true?

Will employment of the WITH CHECK OPTION produce faulty updates?
