 Description
 
 Takes the query in the argument and executes it using a prepared statement. The prepared statement is deallocated,
 so the procedure is mainly useful for executing one off dynamically created queries.
 
 The sys_execute_prepared_stmt prepared statement name is used for the query and is required not to exist.
 
 
 Parameters
 
 in_query (longtext CHARACTER SET UTF8):
 The query to execute.
 
 
 Configuration Options
 
 sys.debug
 Whether to provide debugging output.
 Default is 'OFF'. Set to 'ON' to include.
 
 
 Example
 
 mysql> CALL sys.execute_prepared_stmt('SELECT * FROM sys.sys_config');
