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

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. See
[select].

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;
