DEALLOCATE

Applies to: ❌ Data 360 SQL ✅ Tableau Hyper API

Deallocate a prepared statement.

DEALLOCATE is used to deallocate a previously prepared SQL statement. If you do not explicitly deallocate a prepared statement, it is deallocated when the session ends.

For more information on prepared statements, see PREPARE.

PREPARE This optional key word is ignored and has no semantical meaning.

<name> The name of the prepared statement to deallocate.

ALL Deallocate all prepared statements.

The SQL standard includes a DEALLOCATE statement, but it is only for use in embedded SQL.
