Hvordan kan jeg beregne en alder ud fra en fødselsdato?

• Givet et felt, der indeholder fødselsdage, beregn aktuel alder.

Forespørgslen skal være

SELECT "DateNaissance", 
CASE WHEN MONTH(CURRENT_DATE) < MONTH("DateNaissance") OR ( MONTH(CURRENT_DATE) = MONTH("DateNaissance") AND DAY(CURRENT_DATE) < DAY("DateNaissance") ) 
THEN CAST((YEAR(CURRENT_DATE) - YEAR("DateNaissance") -1) AS VARCHAR) || ' ans' 
ELSE CAST((YEAR(CURRENT_DATE) - YEAR("DateNaissance") ) AS VARCHAR) || ' ans'END AS "Age"FROM "Table1"

For at beregne alder på den nærmeste dag:

Forespørgslen ser sådan ud

SELECT "DateNaissance", "Nom", YEAR(NOW())-YEAR("DateNaissance")-
CASE WHEN (MONTH( NOW() ) < MONTH("DateNaissance") OR ( MONTH( NOW() ) = MONTH("DateNaissance") AND 
DAY( NOW() ) < DAY ("DateNaissance"))) THEN 1 ELSE 0 END AS "ans", 
MONTH(NOW())-MONTH("DateNaissance") +
CASE WHEN MONTH(now()) <= MONTH("DateNaissance") AND DAY(NOW()) < DAY("DateNaissance")
THEN 11 ELSE
CASE 
WHEN MONTH(NOW()) < MONTH("DateNaissance") AND DAY(NOW()) >= DAY("DateNaissance")
THEN 12 ELSE
CASE WHEN MONTH(NOW()) > MONTH("DateNaissance") AND DAY(NOW()) < DAY("DateNaissance")
THEN -1 ELSE 0
END
END
END AS "mois", 
DATEDIFF('DAY', CAST(YEAR(NOW()) || '-' || RIGHT( 0 || MONTH(NOW())  - casewhen DAY(NOW()) < DAY("DateNaissance")
THEN 1 ELSE 0
END, 2) || '-' || RIGHT( 0 || DAY("DateNaissance"), 2) AS DATE) , NOW() ) AS "jours" FROM "Table1"
