data base error

[Sevo]

I keep getting this data base error sent to my email. I have optimized and repaired the tables.. any idea what this means

Database error in vBulletin 3.7.3:

Invalid SQL:

UPDATE session
SET lastactivity = 1223667039, inforum = 0, inthread = 0, badlocation = 0, useragent = 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; SLCC1; .NET CLR 2.0.50727; Media Center PC 5.0; .NET CLR 3.0.04506)'
WHERE sessionhash = 'dd8d877f2edcbbe5c7afe1bc9d897662';

MySQL Error : Data too long for column 'useragent' at row 1
Error Number : 1406

Found this on the boards.. just set it to "true".. lets see if that fixed it

What version of MySQL are you using? Have you enabled the following option in includes/config.php:

$config['Database']['force_sql_mode'] = true;
