获取每个ID列的最大值

Question

在下面的查询中，我希望获取每个USERID的SEQNBR字段的最大值，其中该USERID不包含状态值为'CLE'的行。

我能够按每个USERID检索MAX SEQNBR行，但是它并不排除USERID所在的位置，因为它们在表中具有值“ CLE”的行。

由于最终将运行查询的环境的限制，我想避免在SELECT子句中使用公用表表达式（CTE）和子查询。

SELECT A.USERID, (CONVERT(CHAR(10),A.TEST_DT,121))AS 'TEST_DATE', A.TYPE_CD, 
 (CONVERT(CHAR(10),A.NEXT_TEST_DT,121))AS 'EXPIRE_DATE', B.STATUS1, 
 B.MGR_CLR, B.COMMENT, C.COMPANY, D.DESCR, E.DESCR, 
 F.LAST_NAME, F.FIRST_NAME, B.SEQNBR 
FROM ((((((TEST_PLACEMENT A 
LEFT OUTER JOIN  TEST_STATUS B ON  B.USERID = A.USERID AND B.TEST_DT 
= A.TEST_DT ) 
LEFT OUTER JOIN  (PS_JOB C INNER JOIN PS_EMPLMT_SRCH_QRY C1 ON (C.USERID = 
C1.USERID AND C.EMPL_RCD = C1.EMPL_RCD )) ON  
C.USERID = A.USERID ) 
LEFT OUTER JOIN  PS_JOBCODE_TBL D ON  D.JOBCODE = C.JOBCODE ) 
LEFT OUTER JOIN  PS_DEPARTMENT_VW E ON  E.DEPTID = C.DEPTID ) 
LEFT OUTER JOIN  (PS_JOB G INNER JOIN PS_EMPLMT_SRCH_QRY G1 ON (G.USERID = 
 G1.USERID AND G.EMPL_RCD = G1.EMPL_RCD )) ON  
 G.POSITION_NBR = C.REPORTS_TO AND G.EFFDT = (SELECT MAX( H.EFFDT) 
 FROM PS_JOB H, PS_EMPLMT_SRCH_QRY H1 
 WHERE H.USERID = H1.USERID 
 AND H.EMPL_RCD = H1.EMPL_RCD 
 AND ( G.POSITION_NBR = H.POSITION_NBR )) ) 
LEFT OUTER JOIN  (PS_NAMES F INNER JOIN PS_PERALL_SEC_QRY F1 ON (F.USERID = 
F1.USERID )) ON  F.USERID = A.USERID ) 
WHERE ( ( 
 C.JOB_INDICATOR = 'P' 
 AND B.SEQNBR = 
  (SELECT MAX(BB.SEQNBR) FROM TEST_STATUS BB
   WHERE  BB.USERID = B.USERID AND BB.STATUS1 <> 'CLE')
   --GROUP BY BB.STATUS1)
 AND G.EFFSEQ = 
    (SELECT MAX(G_ES.EFFSEQ) FROM PS_JOB G_ES 
    WHERE G.USERID = G_ES.USERID 
      AND G.EMPL_RCD = G_ES.EMPL_RCD 
      AND G.EFFDT = G_ES.EFFDT) )))

有问题的代码是：

  (AND B.SEQNBR = 
  (SELECT MAX(BB.SEQNBR) FROM TEST_STATUS BB
  WHERE  BB.USERID = B.USERID AND BB.STATUS1 <> 'CLE')
  --GROUP BY BB.STATUS1)) 

这是现在主查询中的示例数据：

这是期望的结果（基于上面的原始示例）：

如您所见，已删除USERID 1和3，因为它们每个都具有状态为'CLE'的行，并且删除了具有SEQNBR 37的USERID 5的行，因为它不是该USERID的MAX SEQNBR（SEQNBR 38是用于USERID 5）。

Answer 1

您需要测试所有行

SELECT MAX(BB.SEQNBR) 
FROM TEST_STATUS BB
WHERE BB.USERID = B.USERID 
  and not exists (select 1 
                  from TEST_STATUS cc 
                  where ccUSERID = BB.USERID 
                  AND cc.STATUS1 = 'CLE')

Answer 2

And b.seqnbr=(Select max(bb.seqnbr) from     TEST_STATUS bb
Where bb.user_id not in (
Select t2.user_id from TEST_STATUS t2 where t2.status='CLE'
)
and bb.user_id=b.user_id
Group by bb.user_id)
