How about something like...

SELECT semen.idmare,semen.identification,;
       cv_gender.name as namemare,;
       cv_name.name as namehorse,;
       semen.value;
FROM semensales semen;
JOIN cv cv_name ON semen.identify=cv_name.idfield;
JOIN cv cv_gender ON semen.idmare=cv_gender.idfield;
ORDER BY semen.idmare,semen.identify

>The problem is that i have two IDs in the table SEMENSALES pointing to the same id on table CV, let me explain you with this example:
>
>in table SEMENSALES:
>IDMARE IDENTIFICATION SEMENVALUE
>1 3 15
>1 4 30
>2 3 10
>
>In table CV
>IDENTIFICATION NAME GENDER
>1 LAMA MARE
>2 CHICA MARE
>3 PEPE HORSE
>4 LOCO HORSE
>
>
>the querie output should be:
>IDMARE IDENTIFICATION NAMEMARE NAMEHORSE SEMENVALUE
>1 3 LAMA PEPE 15
>1 4 LAMA LOCO 30
>2 3 CHICA PEPE 10
