This is a real 2006 post:
"Let's say I have a table of users, and each user has a list of categories. I could store each user's categories as TEXT with delimeters like "cat1|cat2|cat3"
But then I need to be able to get a full list of everyone's categories, without duplicates. Retrieving all the categories, exploding them, and then removing the duplicates is a bit slow. Is there a better method?"
What worked 25 years ago still works today.
