Question

I’ve built this query to give me a list of how much IMPORTE each COD_ZONA has done in the current month. The date is indicated by FECHA_EMIS and COD_CLIENT is the link between the two tables.

SELECT GVA12.FECHA_EMIS, GVA12.IMPORTE, GVA14.COD_ZONA
FROM GVA12 INNER JOIN GVA14 ON GVA12.COD_CLIENT = GVA14.COD_CLIENT
GROUP BY GVA12.FECHA_EMIS, GVA12.IMPORTE, GVA14.COD_ZONA
HAVING (((GVA12.FECHA_EMIS)=Month(curDate())));

It gives an empty table.

@bluefeet this is how I would like the final table

COD_ZONA            IMPORTE
1                   1457.56
16                  127.45

Answer 1

It sounds like you need to use this, apply the Month() function to both the GVA12.FECHA_EMIS and the curDate():

SELECT GVA12.FECHA_EMIS, GVA12.IMPORTE, GVA14.COD_ZONA
FROM GVA12 INNER JOIN GVA14 
  ON GVA12.COD_CLIENT = GVA14.COD_CLIENT
WHERE Month(GVA12.FECHA_EMIS)=Month(curDate())
GROUP BY GVA12.FECHA_EMIS, GVA12.IMPORTE, GVA14.COD_ZONA

If you want to compare both month and year, then I would use:

SELECT GVA12.FECHA_EMIS, GVA12.IMPORTE, GVA14.COD_ZONA
FROM GVA12 INNER JOIN GVA14 
  ON GVA12.COD_CLIENT = GVA14.COD_CLIENT
WHERE Month(GVA12.FECHA_EMIS)=Month(curDate())
  AND Year(GVA12.FECHA_EMIS)=Year(curDate())
GROUP BY GVA12.FECHA_EMIS, GVA12.IMPORTE, GVA14.COD_ZONA

This would make sure that the month and year are equal.

If you want a sum() then you would use:

SELECT GVA14.COD_ZONA, sum(GVA12.IMPORTE)
FROM GVA12 INNER JOIN GVA14 
  ON GVA12.COD_CLIENT = GVA14.COD_CLIENT
WHERE Month(GVA12.FECHA_EMIS)=Month(curDate())
  AND Year(GVA12.FECHA_EMIS)=Year(curDate())
GROUP BY GVA14.COD_ZONA
