找不到MYSQL变量

Question

I have an SQL database which have a 'project' varchar column within one of the tables. When i insert variables into this column via my php pages (eg; project = WT) when i do a select query where project = 'WT' nothing comes up. What makes it even stranger, if i edit the value via phpMyAdmin panel to the same value it is then able to be found in the select query.
