> No offense, but that sounds like sick application design Offense taken :) Well, you don't know the whole picture, so I can see why this would look bad to you. That's why asked any other ideas. The problem I need to solve is this: I have main table with lets say: 11 | Pears 100 | Plums 9 | Apples 5 | Oranges 10 | Cranberries Now, I need to create another table with options for each of the above. So for the apples: ID | colors_available | favourite_color | kind | favourite kind | Other similar options ... 9 | red, green, yellow, ...infinity | red | Granny smith, Golden delicious, ... infinity | Granny smith | Other similar values What I'm trying to do is to keep the options for each froot in one row, as opposed to creating separate table for colors, kind, etc. I realize that I could create separate tables for colors, kind, etc, and separate tables for favourite colors and favourite kind, but this would involve accessing four different tables in this case. I guess, I can always set up views with joins, but could not come up with a good way to query this in a one returned row, e.g.: ID | Name | colors | fav_col | kind | fav_kind | etc. 11 | Apples | red, green, etc. | red | Granny smith, Golden delicious.. | Granny smith | etc. ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
