Hi, What do you obtain with : Select FK_partic, Sum(IF(insumo_or = "Animal1", cantidad_or, 0) ) AS "Animal1", Sum(IF (insumo_or = "Animal2", cantidad_or, 0) ) AS "Animal2", Sum(IF (insumo_or = "Animal3", cantidad_or, 0) ) AS "Animal3", Sum(IF (insumo_or = "Animal4", cantidad_or, 0) ) AS "Animal4", Sum(IF (insumo_or = "Animal5", cantidad_or, 0) ) AS "Animal5", Sum(IF (insumo_or = "Animal6", cantidad_or, 0) ) AS "Animal6" FROM tbl_ISv2CROriginal Group by FK_partic

I've got the next query, but it keeps giving the next error: "#1241 - Operand should contain 1 column(s)" /*GENERAL EXPLANATION OF THE QUERY I work in a project to give animals to farmers: I have two tables: tbl_ISv2CRfamilia with the families which are going to receive animals. (PK_partic, int(11), Autonumbering ID (PK); FK_IS; varchar(255); Foreign key which conects to the project table nombre_partic, varchar(255), Name of the family OB_familia, varchar(255), community of the family) tbl_ISv2CROriginal with the animales they actually have received. (FK_partic, int(11), Foreign key which conects to the family ID insumo_or, varchar(255), Animal given cantidad_or, int(11), number of animals given of this specie) And I need to have a table like this: Family, animal1, animal2, animal3, ..., animaln John Smith 3 4 0 1 3 ... 0 */ The query and subquiery is as follows. SELECT tbl_ISv2CRfamilia.PK_partic, tbl_ISv2CRfamilia.FK_IS, tbl_ISv2CRfamilia.OB_familia, (SELECT Sum( IF ( insumo_or = "Animal1", cantidad_or, 0 ) ) AS "Animal1", Sum( IF ( insumo_or = "Animal2", cantidad_or, 0 ) ) AS "Animal2", Sum( IF ( insumo_or = "Animal3", cantidad_or, 0 ) ) AS "Animal3", Sum( IF ( insumo_or = "Animal4", cantidad_or, 0 ) ) AS "Animal4", Sum( IF ( insumo_or = "Animal5", cantidad_or, 0 ) ) AS "Animal5", Sum( IF ( insumo_or = "Animal6", cantidad_or, 0 ) ) AS "Animal6" FROM tbl_ISv2CROriginal GROUP BY FK_partic ) FROM tbl_ISv2CRfamilia INNER JOIN tbl_ISv2CROriginal ON tbl_ISv2CRfamilia.PK_partic = tbl_ISv2CROriginal.FK_partic GROUP BY FK_partic What is wrong with that? I have tried everything, and no solution. Thanks in advance.
