Question

我在这个查询中遇到错误。第一个内部查询在我们独立运行时正确执行。但是当我在完整查询中包含相同内容时，它会提示错误。

UPDATE GL_BudgetPlanDetails bpd 
SET (CommittedAmt07) = (
        SELECT SUM (case
            when fa.amtacctdr > 0 then (fa.amtacctdr*-1)
            when fa.amtacctcr > 0 then fa.amtacctcr else 0 end )
        FROM fact_acct fa
        WHERE fa.datetrx between '2014-09-01' and '2014-09-30'
          AND fa.isactive ='Y'
          AND fa.account_ID =758
          AND fa.AD_Client_ID =11
          AND fa.AD_Org_ID =50001)
WHERE (
        (
            SELECT gbp.c_year_id
              FROM GL_BudgetPlan gbp
             WHERE gbp.GL_BudgetPlan_ID = bpd.GL_BudgetPlan_ID
               AND gbp.isactive ='Y'
        ) = '2014'
      )
AND bpd.account_ID =758

Answer 1

删除CommittedAmt07的括号

UPDATE GL_BudgetPlanDetails bpd SET Period01Amt =（SELECT SUM（fa.amtacctdr＆gt; 0时的情况，然后fa.amtacctcr＆gt; 0时的情况（fa.amtacctdr * -1））然后fa.amtacctcr else 0 end）FROM fact_acct fa WHERE fa.datetrx介于'2014-09-01'和'2014-09-30'之间并且fa.isactive ='Y'和fa.account_ID = 758 AND fa.AD_Client_ID = 11 AND fa.AD_Org_ID = 50001）WHERE（（SELECT gbp.c_year_id FROM GL_BudgetPlan gbp WHERE gbp.GL_BudgetPlan_ID = bpd.GL_BudgetPlan_ID AND gbp.isactive ='Y'）='2014'）AND bpd.account_ID = 758

Answer 2

我认为问题是（）arround CommittedAmt07，因此您的查询应该看起来像

UPDATE GL_BudgetPlanDetails bpd 
SET CommittedAmt07 = (
        SELECT SUM (case
            when fa.amtacctdr > 0 then (fa.amtacctdr*-1)
            when fa.amtacctcr > 0 then fa.amtacctcr else 0 end )
        FROM fact_acct fa
        WHERE fa.datetrx between '2014-09-01' and '2014-09-30'
          AND fa.isactive ='Y'
          AND fa.account_ID =758
          AND fa.AD_Client_ID =11
          AND fa.AD_Org_ID =50001)
WHERE (
        (
            SELECT gbp.c_year_id
              FROM GL_BudgetPlan gbp
             WHERE gbp.GL_BudgetPlan_ID = bpd.GL_BudgetPlan_ID
               AND gbp.isactive ='Y'
        ) = '2014'
      )
AND bpd.account_ID =758;

如果您查看here，可以看到如果您只更新一列，则不需要括号。但是你需要使用它们用某种数组更新它们。请参阅文档

中的此示例

UPDATE weather SET (temp_lo, temp_hi, prcp) = (temp_lo+1, temp_lo+15, DEFAULT)
WHERE city = 'San Francisco' AND date = '2003-07-03';

同样对于9.3，他们声明从SELECT语句填充它还没有被发现（在链接页面的最低点）
