Syntax
------

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

Description
-----------

This statement is similar to SHOW WARNINGS, except that instead of displaying
errors, warnings, and notes, it displays only errors.

The LIMIT clause has the same syntax as for the 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;

The value of error_count might be greater than the number of messages
displayed by SHOW WARNINGS if the max_error_count system variable is set so
low that not all messages are stored.
