Thanks for all the suggestions, I have tried all and more and still can't get this quite right. If there is a better forum for these question, please point me to it and I will take this somewhat off topic thread elsewhere.
My table structure is like so:
tbl_1
id area_1 area_2 1 2 3 2 1 2 3 5 0tbl_2
id area_name 1 funding 2 research 3 new 4 ongoing 5 otherSo, I need to display all the records in tbl_1 and show the values for the fields area_1 and area_2 as their area_name field from tbl_2. I must display each record from tbl_1 only once. I know I am close, but I just can't get this to work. The closest I have gotten is this: SELECT DISTINCT a.area_name area_a, b.area_name area_b FROM tbl_1 x, tbl_2 a, tbl_2 b WHERE x.area_1 = a.id OR x.area_2 = b.id GROUP BY x.id But this ALWAYS returns the area_name (funding) in the value of area_b (have no idea why) Thanks for any help. It is appreciated. - Charles On Friday, March 7, 2003, at 01:42 PM, Jim Lucas wrote:

Almost there. Here is what I have: SELECT x.id, x.headline, x.description, a.area area_a, b.area area_b FROM tbl_funding x, tbl_dra a, tbl_dra b GROUP BY x.id LIMIT 0 , 30 The problem is that $array[area_a] and $array[area_b] display the same info.

How do I echo the values for a.id and b.id? Thnks CharlesI presume you mean area_name... Try this -> SELECT a.area_name as area_a, b.area_name as area_b FROM tbl_1 x, tbl_2 a, tbl_2 b Then you can refer to the columns as $array['area_a'] and $array['area_b'] HTH Rich
