Question

我想在现有查询中添加一个字段，该字段不会受到影响＆＃39; Where function＆＃39;

例如，

这是原始代码......

SELECT SHELL_Payables.PoolNum, 
A.[Code], B.[Program] AS Program, A.PayableAmt, C.ReceivableAmt  INTO [New Data]

FROM A INNER JOIN B ON A.ID=B.ID 
              INNER JOIN C  ON A.Num=B.Num

WHERE (((A.AccountingPeriod)<=[AccountingYearMonth]));

我想再次添加A.PayableAmt，但这次不应将(accountingperiod <= accountingyearMonth)条款应用于此字段......

有什么想法吗？非常感谢。

要使用union和select into，您需要将查询写成以下内容：

SELECT *
INTO [New Data]
FROM (
    SELECT PoolNum
        ,A.[Code]
        ,B.[Program] AS Program
        ,A.PayableAmt
        ,C.ReceivableAmt
    FROM A
    INNER JOIN B ON A.ID = B.ID
    INNER JOIN C ON A.Num = B.Num
    WHERE A.AccountingPeriod <= AccountingYearMonth

    UNION 

    SELECT PoolNum
        ,A.[Code]
        ,B.[Program] AS Program
        ,A.PayableAmt
        ,C.ReceivableAmt
    FROM A
    INNER JOIN B ON A.ID = B.ID
    INNER JOIN C ON A.Num = B.Num
    )

更新

如果您想将另一个PayableAmt列添加到同一行，也许您可以加入表格A：

SELECT   t.PoolNum
        ,a.[Code]
        ,a.[Program] AS Program
        ,t.PayableAmt
        ,a.PayableAmt AS NewPayableAmt
        ,C.ReceivableAmt
INTO [New Data]
FROM A
LEFT JOIN 
 (
    SELECT 
         PoolNum
        ,A.[Code]
        ,B.[Program] AS Program
        ,A.PayableAmt
        ,C.ReceivableAmt
    FROM A
    INNER JOIN B ON A.ID = B.ID
    INNER JOIN C ON A.Num = B.Num
    WHERE A.AccountingPeriod <= AccountingYearMonth
   ) t
   ON t.Code = A.Code --assuming this is unique
INNER JOIN B ON A.ID = B.ID
INNER JOIN C ON A.Num = B.Num

ACCESS SQL查询：添加新字段？
