Don't.
Never store comma delimited data in a DB - it's a total PITA to work with.
Instead, use a second DB table which contains a foreign key to the original table row, and a single element of your data. You can then pick up the relevant data with a simple JOIN or WHERE clause.

Storing it as comma delimited seems easy, but causes massive headaches later when you try to do anything useful with the data.
