具有两个'HAVING'条件的Oracle查询

Question

我有一个查询，我想有两个HAVING条件

• 第一个条件是总和超过6000（我有完成）

• 第二个条件是COUNT（1）CNT大于1（其中我需要帮助）

  SELECT SYSDATE,
         CUSTOMER.CIF_NO,
         CUSTOMER.LONG_NAME_ENG,
         TRANSTYPE.short_desc_Eng,
         LOCATION.LONG_DESC_ENG ,
         COUNT(1) CNT,
         SUM(TRANS.AMOUNT) SM
    FROM TRANS, CUSTOMER, TRANSTYPE, LOCATION
   WHERE TRANS.TRS_AC_CIF = CUSTOMER.CIF_NO
     AND TRANS.BRANCH_CODE = LOCATION.BRANCH_CODE
     AND TRANS.COMP_CODE = LOCATION.COMP_CODE
     AND TRANSTYPE.COMP_CODE = TRANS.COMP_CODE
     AND TRANSTYPE.TYPE IN ( 'D' ,  'T' )
     AND TRANSTYPE.CODE = TRANS.TRX_TYPE
     AND TRANS.STATUS = 'P'
     AND TRANS.TRS_TYPE = 'R'
     AND TRANS.CB_IND = 'C'
   GROUP BY CUSTOMER.CIF_NO ,CUSTOMER.LONG_NAME_ENG, 
            TRANSTYPE.short_desc_Eng,  LOCATION.LONG_DESC_ENG 
  HAVING SUM(TRANS.AMOUNT) > 6000 
  ---------------------------
  second having here 
  ----------------------------
   ORDER BY CUSTOMER.CIF_NO, CUSTOMER.LONG_NAME_ENG, LOCATION.LONG_DESC_ENG
  

Answer 1

不能在SELECT语句中指定多个HAVING子句，例如这是一种侵犯。但是添加您所需的条件，例如

HAVING SUM(TRANS.AMOUNT) > 6000 AND COUNT(1) > 1 

OR

HAVING SUM(TRANS.AMOUNT) > 6000 OR COUNT(1) > 1

只要

• SQL语句中存在GROUP BY子句
• 汇总发生在HAVING子句中

P.S。将查询语法转换为在表中使用explicit JOIN子句而不是旧式逗号分隔的JOIN的语法，并使用aliases作为表名
