Join two tables and filter them with where clause

Question

I have problem getting the SQL output I want.

I have two tables like this:

tblOrder

ID    User    Status
1      1         0
2           


        

Answer 1

The main problem I found that I had done was write O.ID = OI.ID instead of O.ID = OI.OrderID. Thats why I only got one row per ID. I should have seen that but I only thought of other problems. Thanks for the help!
