Hello,

I have a script that runs a series of summary queries. On the last =
query, it is timing out, returning the message:=20

DBD::mysql::st execute failed: Lost connection to MySQL server during =
query at stats_tester.pl line 56.=20

If run from the mysql prompt, the problem query takes about 31 =
seconds. The column in question is a tinytext and it is indexed with =
about 2 million rows.

The script is only being run from the command line at the moment, so =
it's not a server issue. I am using the default mysql-huge settings that =
came with the install. Is there a param I can pass to the connect() to =
make the script wait for longer before quitting?=20

Thanks in advance for any help.

Rob

http://dev.mysql.com/doc/mysql/en/Server_system_variables.ht ml

And you should be able to set/change them using a
$dbh->do("SET variable_name = $value")

Looking over the list, the only one that I see that ~30 sec is the
net_read_tiemout, so you might want to start there.

I don't see why DBD::mysql should drop connection while the client does not, so
if that does not help, code and traces and schemata would be come in handy...


HTH,
