             Description
             Formats a normalized statement, truncating it if it is > 64 characters long by default.
             To configure the length to truncate the statement to by default, update the `statement_truncate_len`
             variable with `sys_config` table to a different value. Alternatively, to change it just for just
             your particular session, use `SET @sys.statement_truncate_len := <some new value>`.
             Useful for printing statement related data from Performance Schema from
             the command line.
             Parameters
             statement (LONGTEXT):
               The statement to format.
             Returns
             LONGTEXT
             Example
             mysql> SELECT sys.format_statement(digest_text)
                 ->   FROM performance_schema.events_statements_summary_by_digest
                 ->  ORDER by sum_timer_wait DESC limit 5;
