I have four tables
TableA:
- id1
- id2
- id3
- value
TableB:
- id1
- desc
TableC:
- id2
- desc
TableD:
- id3
- desc
What I need to do is to check if all combinations of id1 id2 id3 from table B C and D exist in the TableA. In other words, table A should contain all possible combinations of id1 id2 and id3 which are stored in the other three tables.
