At the time I reported this bug back in February: http://
bugs.mysql.com/bug.php?id=8684 I was pleased to see it apparently
fixed so fast. I wasn't yet using MySQL 5, so I couldn't get the
fix. I am now upgrading to 5 using mysql 5.0.15, and I find I still
face much the same problem. Despite much rummaging in the docs, the
log-warnings options still seem completely undocumented (it gets a
few mentions as a startup option, but nowhere does it say where the
messages disappear to), and despite having it 'enabled' (it's
difficult to know what to set it to as it has no documentation) in
my.cnf, I'm not seeing warnings logged anywhere. I had assumed
they'd go in the error log, but that seems to be mostly empty.
Putting it in the regular or binary logs seems hopeless - I'm
trying to pick out numerous (> 20000) warnings that happen during a
1.2 million record mysqldump import. Anything that I've tried for
processing text log files (grep/sed/awk/vi etc) takes several hours
at a time and usually finds nothing of use.
If I could see the warnings then I could probably fix the problem
that's causing them at source.
Help! If there was at least a user note on warnings I could be
saved - can anyone tell me where I might find the warning messages,
along with the query that caused them?
The log-warnings option doesn't do what you want. It will cause the
mysqld server log more internal errors. Non-critical errors such as
network disconnects will be logged into the error log with that setting.
The option you want it is the --show-warnings option for the mysql
client itself.
mysql --show-warnings db < file.sql
Should output the errors to screen afaik. You can redirect it to a
file or similar if you want.

Harrison
