La fonction SQL DAYOFWEEK(date) fournit le numéro du jour de la semaine de la date indiquée en paramètre.
Le numéro renvoyé par la fonction DAYOFWEEK s’interprète ainsi :
1 = dimanche, 2 = lundi…, 7 = samedi.
Exemple :
SELECT DAYOFWEEK(EcritureValidDate) AS NumJourSem, EcritureNum
FROM ECRITURES
WHERE DAYOFWEEK(EcritureValidDate)=1 OR DAYOFWEEK(EcritureValidDate)=7;
SELECT DAYOFWEEK(EcritureValidDate) AS NumJourSem, EcritureNum
FROM ECRITURES
WHERE DAYOFWEEK(EcritureValidDate)=1 OR DAYOFWEEK(EcritureValidDate)=7;
SELECT DAYOFWEEK(EcritureValidDate) AS NumJourSem, EcritureNum FROM ECRITURES WHERE DAYOFWEEK(EcritureValidDate)=1 OR DAYOFWEEK(EcritureValidDate)=7;
