Question

Right now I\'m still a beginner in databases and still learning all about it. I have a problem with the design of my database and I don\'t really know where to go from here. Bas

Answer 1

If this is all you are storing, you can add an extra two fields in the database One called Guitar and has a 1 when the brand applies to a guitar (so all of them at the moment) and another field called Bass which only has a 1 on the brands which uses a bass.

In your filter you can add "where g.Bass==1"

This will only return the Bass brands.

However, if you intend to expand on the instruments, you should create a separate table which links the type of instrument to the brands.

eg

Type Brand Guitar 1 Guitar 2 Guitar 3 Guitar 4 etc Bass 1 Bass 2 Bass 5

Then link the two tables together in the where.
