This is a pain and it definately means, that you have choosen the WRONG data model for your application. It is simply wrong, having comma separated values in your columns, instead of having a 1:n (or even n:n) relationship between some entities. I know that you dont like this answer and it does not make you happy, but its better to have a sudden death instead of a pain without end. I am sorry for the bad explanation, in german the idiom says "besser ein Ende mit Schrecken, als ein Schrecken ohne Ende". Maybe a translator can translate this into an appriopriate engllish idiom.
Anyway, you have to change your data design and your application, otherwise you will not ever have a good performing application.
