Question

好的，这是问题，

   SELECT CTE.TECHNICIANID, SUM(TLEVEL) AS TLEVEL, TECH.PASSEDDRUGTEST, TECH.PASSEDBACKGROUNGCHECK, TECH.FIRSTNAME, TECH.LASTNAME, 
        CM.CITYID, CM.ADDRESS, CM.EMAIL, CM.PHONENUMBER, CM.ZIPCODE, CNTRY.COUNTRYNAME, SM.STATENAME,
         CM.LATITUDE, CM.LONGITUDE FROM CTE
        INNER JOIN TECHNICIAN TECH ON CTE.TECHNICIANID = TECH.TECHNICIANID 
        INNER JOIN SERVICEORDER SO ON SO.SERVICEORDERID = @SERVICEORDERID
        INNER JOIN CONTRACT CONT ON SO.CONTRACTID = CONT.CONTRACTID
        INNER JOIN CONTACTMASTER CM ON CM.CONTACTID = TECH.CONTACTID
        INNER JOIN COUNTRYMASTER CNTRY ON CM.COUNTRYID = CNTRY.COUNTRYID
        INNER JOIN STATEMASTER SM ON SM.STATEID = CM.STATEID
        --WHERE CONT.DRUGSCREENINGREQUIRED = CASE CONT.DRUGSCREENINGREQUIRED  WHEN 'TRUE' THEN TECH.PASSEDDRUGTEST END AND
        --CONT.BACKGROUNDCHECKREQUIRED = CASE CONT.BACKGROUNDCHECKREQUIRED WHEN 'TRUE' THEN TECH.PASSEDBACKGROUNGCHECK END
        GROUP BY CTE.TECHNICIANID, TECH.PASSEDDRUGTEST, TECH.PASSEDBACKGROUNGCHECK,CM.LATITUDE, TECH.FIRSTNAME, TECH.LASTNAME, 
        CM.CITYID, CM.ADDRESS, CM.EMAIL, CM.PHONENUMBER, CM.ZIPCODE, CNTRY.COUNTRYNAME, SM.STATENAME, CM.LONGITUDE ORDER BY TLEVEL DESC

使用where子句查看查询中的注释部分，当需要drugscreening为true时，我想要的是我想要passeddrugtest为true的所有记录否则我不想申请任何条件

修改：当CONT.DRUGSCREENINGREQUIRED和CONT.BACKGROUNDCHECKREQUIRED为真时，我只想使用TECH.PASSEDDRUGTEST和TECH.PASSEDBACKGROUNGCHECK过滤记录。如果它们不是真的，我想要所有记录，无论TECH.PASSEDDRUGTEST和TECH.PASSEDBACKGROUNGCHECK是真还是假。

Answer 1

也许我误解了这个问题，但你能不能这样做吗？

WHERE CONT.DRUGSCREENINGREQUIRED = 'FALSE' OR CONT.DRUGSCREENINGREQUIRED = 'TRUE' AND TECH.PASSEDDRUGTEST = 'TRUE'

Answer 2

如果这些标志是独立的（与问题相反，但在我看来应该如此），您可能会检索不需要检查或检查通过的记录，简而言之如下：

WHERE (CONT.DRUGSCREENINGREQUIRED = 'FALSE' OR TECH.PASSEDDRUGTEST = 'TRUE')
  AND (CONT.BACKGROUNDCHECKREQUIRED = 'FALSE' OR TECH.PASSEDBACKGROUNGCHECK = 'TRUE')

如果你真的想检查passed状态是否有两个标志，那么你可以使用这个模式：

WHERE (    CONT.DRUGSCREENINGREQUIRED = 'FALSE' 
        OR CONT.BACKGROUNDCHECKREQUIRED = 'FALSE'
        OR (     TECH.PASSEDDRUGTEST = 'TRUE' 
             AND TECH.PASSEDBACKGROUNGCHECK = 'TRUE'
           )
      )
