$email="" does not do what you think. It computes the numeric values for both sides and compares. You whould need eq for that. See perlop for that.

Next, you don't need to select Email from the table to check if it is empty or not. Use SELECT COUNT(*) FROM foo and get the number of rows. That way, you know how many rows of data you have. i.e. If you have 0 rows, you have an empty table. (not an empty database)

Update: oops! Thanks 3dan (++)
