Yes you can, it’s through an approach known as dynamic sql. The real question to answer now that you know that is should you. There are a lot of caveats and dangers to dynamic sql that you need to be aware of if you are going to use that approach.
There’s a whole lot of really good info out on the web that can give you more info. A good place to start is here. This has been a good guide on the web for some time.

This is also another good series to read up on.

To be clear dynamic sql has some very good uses… just be careful and wise.
