How to look up SQL error codes quickly in DB2

Quite regularly DB2 complains about my SQL statements and usually returns a cryptic error message including an even more cryptic SQL error code. What I normally do in those situations is looking up the error code in the DB2 Information Center, which takes some time. I just found out that there is an easier way to get at least a short explanation of what an error code means. For example, to look up the error code -161, you can use the following SQL query:

VALUES SQLERRM(-161)

Result:

1
------------------------------------------------------------------------------------------------------
SQL0161N  The resulting row of the insert or update operation does not conform to the view definition.

Nice.
