Usage

Embedded/Interactive/Module/ODBC/JDBC

Description

The statement specified, stored with the name statement-name, is compiled and optimized and thereafter stored in its compiled form in the data dictionary.

The statement can then be executed through the EXECUTE STATEMENT command (see EXECUTE STATEMENT.) A statement that produces a result set (e.g. SELECT), needs a cursor to read it.

You can use the SCROLL option to specify that the result set should be read by a scrollable cursor.

If you use the NO SCROLL option, the result set will only be accessible for no-scroll cursors.

If you do not specify an option, the result set can be used by both scroll and no-scroll cursors.

Once the precompiled statement has been created, only cursors with the correct scroll mode can be used to read the result set.
