27.4.4.3 The execute_prepared_stmt() Procedure

Contents

Given an SQL statement as a string, executes it as a prepared statement. The prepared statement is deallocated after execution, so it is not subject to reuse. Thus, this procedure is useful primarily for executing dynamic statements on a one-time basis.

This procedure uses sys_execute_prepared_stmt as the prepared statement name. If that statement name exists when the procedure is called, its previous content is destroyed.

Parameters

in_query LONGTEXT CHARACTER SET utf8: The statement string to execute.
