Sto lavorando con una query che contiene l'istruzione "CASE" all'interno della clausola "WHERE". Ma SQL Server 2008 restituisce alcuni errori durante l'esecuzione. Qualcuno può aiutarmi con la query corretta? Ecco la domanda:
SELECT
tl.storenum 'Store #',
co.ccnum 'FuelFirst Card #',
co.dtentered 'Date Entered',
CASE st.reasonid
WHEN 1 THEN 'Active'
WHEN 2 THEN 'Not Active'
WHEN 0 THEN st.ccstatustypename
ELSE 'Unknown'
END 'Status',
CASE st.ccstatustypename
WHEN 'Active' THEN ' '
WHEN 'Not Active' THEN ' '
ELSE st.ccstatustypename
END 'Reason',
UPPER(REPLACE(REPLACE(co.personentered,'RT\\\\',''),'RACETRAC\\\\','')) 'Person Entered',
co.comments 'Comments or Notes'
FROM
comments co
INNER JOIN cards cc ON co.ccnum=cc.ccnum
INNER JOIN customerinfo ci ON cc.customerinfoid=ci.customerinfoid
INNER JOIN ccstatustype st ON st.ccstatustypeid=cc.ccstatustypeid
INNER JOIN customerstatus cs ON cs.customerstatuscd=ci.customerstatuscd
INNER JOIN transactionlog tl ON tl.transactionlogid=co.transactionlogid
LEFT JOIN stores s ON s.StoreNum = tl.StoreNum
WHERE
CASE LEN('TestPerson')
WHEN 0 THEN co.personentered = co.personentered
ELSE co.personentered LIKE '%TestPerson'
END
AND cc.ccnum = CASE LEN('TestFFNum')
WHEN 0 THEN cc.ccnum
ELSE 'TestFFNum'
END
AND CASE LEN('2011-01-09 11:56:29.327')
WHEN 0 THEN co.DTEntered = co.DTEntered
ELSE
CASE LEN('2012-01-09 11:56:29.327')
WHEN 0 THEN co.DTEntered >= '2011-01-09 11:56:29.327'
ELSE co.DTEntered BETWEEN '2011-01-09 11:56:29.327' AND '2012-01-09 11:56:29.327'
END
END
AND tl.storenum < 699
ORDER BY tl.StoreNum
