Join 2 tables (MS Sql 2005)

Hello, I'm sure this is pretty easy, but I can't find a way to do it.

TABLE A:

CODIGO    VENTA    COMPRA
10        100      0
20        100      0
30        100      0

TABLE B:

CODIGO    VENTA    COMPRA
40        0        100
20        0        100
50        0        100

I need to get this in just one select:

CODIGO    VENTA    COMPRA
10        100      0
20        100      100
30        100      0
40        0        100
50        0        100

Been awhile since i've done sql but i believe this should get you what you want.

SELECT CODIGO,VENTA,COMPRA
FROM TableA
GROUP BY CODIGO
UNION ALL
SELECT CODIGO,VENTA,COMPRA
FROM TableB
GROUP BY CODIGO

Give this a whirl, UNION ALL the two together in a subquery and then perform your SUM's
SELECT CODIGO, SUM(VENTA) as VENTA, SUM(COMPRA) as COMPRA
FROM (
   SELECT CODIGO, VENTA, COMPRA
   FROM TableA
   UNION ALL 
   SELECT CODIGO, VENTA, COMPRA
   FROM TableB) a
GROUP BY CODIGO
ORDER BY CODIGO
