SHOW ERRORS [LIMIT [offset,]row_count]SHOW COUNT(*) ERRORSSHOW ERRORS is a diagnostic statement that is similar toSHOW WARNINGS, except that it displays information only for errors, rather than for errors, warnings, and notes.
TheLIMIT clause has the same syntax as for theSELECT statement. SeeSection 13.2.9, “SELECT Statement”.
TheSHOW COUNT(*) ERRORS statement displays the number of errors. You can also retrieve this number from theerror_count variable:
SHOW COUNT(*) ERRORS;SELECT @@error_count;SHOW ERRORS anderror_count apply only to errors, not warnings or notes. In other respects, they are similar toSHOW WARNINGS andwarning_count. In particular,SHOW ERRORS cannot display information for more thanmax_error_count messages, anderror_count can exceed the value ofmax_error_count if the number of errors exceedsmax_error_count.
For more information, seeSection 13.7.5.40, “SHOW WARNINGS Statement”.
