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.
