TCustomSQLQuery.UnPrepare procedure

Declaration

procedure UnPrepare; virtual

Description

Unprepare will unprepare a prepared query. This means that server resources for this statement are deallocated. After a query was unprepared, any ExecSQL or Open command will prepare the SQL statement again.

Several actions will unprepare the statement: Setting the SQL property, setting the Transaction property or setting the Database property will automatically call UnPrepare. Closing the dataset will also unprepare the query.

Errors

If the SQL server cannot unprepare the statement, an exception may be raised.
