Here the better solution, which doesn’t require not built-in functions:

SELECT US_USERNAME, GR_GROUP_NAME
FROM USERS, GROUPS
WHERE SUBSTRING(US_GROUP, GR_GROUP_ID + 1, 1) = 1

Mirko,
You are a genius. This was the exact query I was looking for.

Thanks for this post. I found it very interesting since I was having the same issue. I figured out a simpler way to realize the join between the USERS and GROUPS table. For me it’s working fine:

SELECT USERS.US_USERNAME,
GROUPS.GR_GROUP_ID,
GROUPS.GR_GROUP_NAME
FROM USERS, GROUPS
WHERE(INSTR(US_GROUP,1,1,1)-1) =GROUPS.GR_GROUP_ID

Actually, there is a posting on that website where someone has used the same technique to store whether an “agent” is allowed to sell a “product line”.

This makes writing a feature to ‘Find Agency by Product Line’ harder than it should be.

Cheers,
Stuart.

This is a good example of how NOT to create a database many-to-many relationship. I can't believe that a mature product that is used by thousands of people has code like this in it. Definitely deserves to be on The Daily WTF.
