             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');
