SHOW ERRORS [LIMIT [offset,] row_count]
SHOW COUNT(*) ERRORS

SHOW ERRORS is a diagnostic statement that is similar to SHOW WARNINGS, except that it displays information only for errors, rather than for errors, warnings, and notes.

The LIMIT clause has the same syntax as for the SELECT statement. See Section 13.2.9, “SELECT Statement”.

The SHOW COUNT(*) ERRORS statement displays the number of errors. You can also retrieve this number from the error_count variable:

SHOW COUNT(*) ERRORS;
SELECT @@error_count;

SHOW ERRORS and error_count apply only to errors, not warnings or notes. In other respects, they are similar to SHOW WARNINGS and warning_count. In particular, SHOW ERRORS cannot display information for more than max_error_count messages, and error_count can exceed the value of max_error_count if the number of errors exceeds max_error_count.

For more information, see Section 13.7.5.40, “SHOW WARNINGS Statement”.
