多个Hive中的子查询不起作用

Question

我有一个如下查询：

SELECT T.MTH_END_DT, T.SRC_SYS_CD, T.BTCH_ID
FROM PROD_RCRR.BAL_CNTRL_LOG T
WHERE T.SRC_SYS_CD='SL'
AND T.MTH_END_DT in (SELECT(MAX(MTH_END_DT)) FROM PROD_RCRR.BAL_CNTRL_LOG)
AND T.BTCH_ID in (SELECT(MAX(BTCH_ID )) FROM PROD_RCRR.BAL_CNTRL_LOG)

错误消息显示Hive只能支持一个“in”子句。任何人都可以给我一个解决方案吗？

Answer 1

您可以使用Join ON子句

替换整个事物

SELECT
    T.MTH_END_DT
  , T.SRC_SYS_CD
  , T.BTCH_ID
FROM PROD_RCRR.BAL_CNTRL_LOG T
JOIN ( SELECT
          MAX(MTH_END_DT) ENDT
        , MAX(BTCH_ID )   BTCH
       FROM PROD_RCRR.BAL_CNTRL_LOG ) X
  ON  T.SRC_SYS_CD='SL'
  AND T.MTH_END_DT = X.ENDT
  AND T.BTCH_ID = X.BTCH
