How to create a dummy column to contain a name based on a number of checkbox values

I have a table containing a number of columns relating to check boxes on a form. For example these check box values correspond to ice cream flavours so each time a flavour is checked on the form, a 1 is stored under the flavour in the table. I need to create a dummy column that will store the ice cream flavour based around a case statement that will say, if checkbox.vanilla = 1, then place the word vanilla under the flavours (dummy column).
