You can, but you have to be very careful of a sql injection attack.
One strategy would be to make sure that the user/application only has read access to the data. Create a sqlcommand and feed the text from the editor into the sqlcommand. Then just execute the sqlcommand.
Again, be very careful, if permissions are not perfect you could end up losing data. In fact I would highly recommend that you find an alternative solution

Hi,

Create a separate DB user with readonly access on the DATABASE. so, connect DB with readonly DB user in query page alone.
