Oracle Forms Developer – Form Builder Reference, Volume 1

Optimize SQL Processing (Forms Runtime)
Description
Specifies that Form Builder is to optimize SQL statement processing in V2-style triggers by sharing
database cursors.
By default, Form Builder assigns a separate database cursor for each SQL statement that a form executes
explicitly in a V2 trigger. This behavior enhances processing because the statements in each cursor need
to be parsed only the first time they are executed in a Forms Runtime session¾not every time.
When you specify OptimizeSQL=NO, Form Builder assigns a single cursor for all SQL statements in V2
triggers. These statements share, or reuse, that cursor. This behavior saves memory, but slows
processing because the SQL statements must be parsed every time they are executed.
You can fine-tune this behavior through the New Cursor Area trigger step characteristic. If a trigger step
that contains a SQL statement has this characteristic turned on, Form Builder assigns a separate cursor to
the statement, in effect overriding the OptimizeSQL parameter for that statement.
Note: OptimizeSQL has no effect on statements in PL/SQL triggers.
