Code:

Invalid SQL:

UPDATE vb_session
SET lastactivity = 1290380872, useragent = 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.12) Gecko/20101026 Firefox/3.6.12 ( .NET CLR 3.5.30729)'
WHERE sessionhash = 'c2d7022bc09df64aa9fa6c85561bfe96';

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