Question

I need compare the sum of one column, this could be less or equal than other value in other table. So I have this, but I don’t know how make the sintax

SELECT sembrado.f_AreaSiembra, tenencia.f_AreaDedicadaCultivos
  FROM Clt_Sembrado as sembrado
  INNER JOIN Fnc_TenenciaUsoTierra as tenencia ON sembrado.c_Fk_IdBoleta = tenencia.c_Fk_IdBoleta
  HAVING (SUM(sembrado.f_AreaSiembra) <= tenencia.f_AreaDedicadaCultivos)  AND (sembrado.c_Fk_IdBoleta = 45550711 AND tenencia.c_Fk_IdBoleta = 45550711)

How can I do this??

thanks

Answer 1

It sounds like you just want the conditions in the where clause: you can still use WHERE within the aggregated.

SELECT
   SUM(sembrado.f_AreaSiembra) as SummedArea,
   (SELECT SUM(f_AreaDedicadaCultivos)
      FROM Fnc_TenenciaUsoTierra
      WHERE c_Fk_IdBoleta = sembrado.c_Fk_IdBoleta)
   AS AreaDedicadaCultivos
FROM
   Clt_Sembrado as sembrado
WHERE
   sembrado.c_Fk_IdBoleta = 45550711
GROUP BY sembrado.c_Fk_IdBoleta
HAVING SUM(sembrado.f_AreaSiembra) <= (SELECT SUM(f_AreaDedicadaCultivos)
      FROM Fnc_TenenciaUsoTierra
      WHERE c_Fk_IdBoleta = sembrado.c_Fk_IdBoleta)

I haven’t tested, so might be small syntax errors.
