Selecting all columns that start with XXX using a wildcard?

Question

I have several columns in my databases with similar names. How do I select those based on the word they start with? Here\'s an example table layout:

Answer 1

Convert your database to one with three columns:

Product_type (vegetable, fruit, etc) 

Name (apple, carrot, etc) 

color (orange, yellow, etc)

Now you can use your wildcard to obtain only a certain type, because it now is IN a columns, not in the header.
