If you want to store an array in a database column, you aren't thinking about databases correctly.

Basically, you want to pull a bunch of data out of a table based on some set of identifying characteristics. So, you either have

• a bunch of different pieces of data, in which case they should be columns in their own right (name, address, city, etc)
• a bunch of data that's the same thing (favorite colors, clothing sizes, etc). Those belong in a child table. So, you'd have an ID for the main row. The second table would have multiple rows with that ID, each having a different value.

I don't have time now, but I'll be glad to provide an example of each kind later. It would also be helpful if you provided exactly what type of data you're trying to work with. Often, a little analysis goes a long way.
