SHOW WARNINGS
Synopsis
SHOW [COUNT(*)] WARNINGS [LIMIT [offset,]count]
Use this statement to display warning
messages, error messages, and notes for previous SQL statements for
the current session. To get a count of the number of such messages,
use the COUNT(*) clause. You cannot use this with
the LIMIT clause. The LIMIT
clause is used to limit the number of messages displayed. An offset
can be given along with the limit to specify a starting point for
displaying messages. This statement is available as of Version 4.1 of
MySQL. Here are a couple of examples of how you can use this
statement:
SHOW WARNINGS; SHOW COUNT(*) WARNINGS;
The first line displays all messages in an ASCII-formatted table. The
second line returns the number of messages. Here's
another example, but with the LIMIT clause:
SHOW WARNINGS LIMIT 3,2;
