What warnings are you getting?

Is the value 1 or '1'?

There nothing wrong with your SQL unless it doesn't match your table.  @hnasr is asking whether it should be the number 1 (without quotes) or the character '1' (with quotes).

@phat_code: that doesn't make much sense as LIKE 'literal w/o wildcard' acts the same as = 'literal w/o wildcard'; therefore, it must be something with data types of the fields maybe? Not disputing the closure or that you solved this by the way. I am happy you figured it out. My concern is if you are going to leave this in the PAQ, it would be great for future readers to truly understand the solution, i.e., if using TEXT columns use ... or something to that effect.

Not sure what you mean Text columns? And who do I give the points too also why didn't it work with equal signs?

You give the points to your own comment as you did to answer the "who do I gives to" question. What I meant by TEXT columns is what is the data type of the columns `Top Level Category`, `Page Category`, `Group Category`. It may have to do with their type. I threw out TEXT as an example. If you don't know, then that is fine. I was just making the point that "why didn't it work with equal signs?" isn't clear from the information in the question. Not an issue for you really, so again no worries if you don't know.

Regards, Kevin
