  Hello.

  I have one table that looks something like this..

  3022224 G 4980 65 3

  3022224 U 4980 596 2

  3022224 G 4980 67 3

  And another that looks something like this..

  28077 1 3022224

  28078 1 3022224

  28079 1 3022224

  I need insert the following into another table based on the two tables above. The long number (3022224) is what I use to join the two original tables.

  28077 1 G 4980 65 3

  28077 1 U 4980 596 2

  28077 1 G 4980 67 3

  28078 1 G 4980 65 3

  28078 1 U 4980 596 2

  28078 1 G 4980 67 3

  28079 1 G 4980 65 3

  28079 1 U 4980 596 2

  28079 1 G 4980 67 3

  Any ideas would be much appreciated.

  Thank you,

  Keith

  Why would you bother, all the data is in the two tables, which you can select anytime. Why would you want to store a bunch of duplicate data. That means that every insert into either of the original tables, would then also mean an insert into the third table. You could simply create a query or a View if you want that data.

  Also, "query help" suggests that you have worked on it, but are stuck.

  What have you got so far ?

  This will get you what you are looking for...

  -- (1) Sample data

  DECLARE @x_p TABLE (xid int, nbr1 int, cid int);

  DECLARE @x_c TABLE (cid int, chr char(1), nbr2 int, nbr3 int, nbr4 int);

  INSERT @x_p VALUES (28077,1,3022224),(28078,1,3022224),(28079,1,3022224);

  INSERT @x_c VALUES (3022224,'G',4980,65,3),(3022224,'U',4980,596,2),(3022224,'G',4980,67,3);

  --(2) The query

  SELECT xid, nbr1, chr, nbr2, nbr3, nbr4

  FROM @x_p xp

  CROSS APPLY @x_c xc
