在MS Access 2003中的查询，帮助使用嵌套的选择

Question

如果我有三个查询，那么查询中的行并不都是相同的。如何编写一个SQL语句，将所有三个查询和它们的所有数据行组合成一个最终查询？

我目前使用的查询保留了一些行，因为行并不都是相等的，而且据我理解，Access不支持完全的外部联接。下面是我目前正在使用的查询：

SELECT
    ZBASED.ACCT_UNIT,
    CCtable.CenterName,
    ZBASED.ACCOUNT,
    ZBASED.ACCOUNT_DESC,
    qryBUD11.Bud11,
    qryBUD10.Bud10,
    qryACTvPROJ.ActvProj10
FROM
    CCtable,
    (
        (ZBASED INNER JOIN qryACTvPROJ ON ZBASED.ACCOUNT=qryACTvPROJ.ACCOUNT)
        INNER JOIN qryBUD11 ON ZBASED.ACCOUNT=qryBUD11.ACCOUNT
    )
INNER JOIN qryBUD10 ON
    ZBASED.ACCOUNT=qryBUD10.ACCOUNT
WHERE
    ZBASED.ACCT_UNIT = [Cost Center] AND
    CCtable.CenterNo = [Cost Center]
ORDER BY ZBASED.ACCOUNT;

qryACTvPROJ

SELECT BUDGET.FISCAL_YEAR, BUDGET.BUDGET_NBR, BUDGET.ACCT_UNIT, BUDGET.ACCOUNT, ZBASED.ACCOUNT_DESC, BUDGET.DB_AMOUNT_01+BUDGET.DB_AMOUNT_02+BUDGET.DB_AMOUNT_03+BUDGET.DB_AMOUNT_04+BUDGET.DB_ AMOUNT_05+BUDGET.DB_AMOUNT_06+BUDGET.DB_AMOUNT_07+BUDGET.DB_AMOUNT_08+BUDGET.DB_AMOUNT_09+BUDGET.DB_AMOUNT_10+BUDGET.DB_AMOUNT_11+BUDGET.DB_AMOUNT_12+BUDGET.CR_AMOUNT_01+BUDGET.CR_AMOUNT_02+BUDGET.CR_AMOUNT_03+BUDGET.CR_AMOUNT_04+BUDGET.CR_AMOUNT_05+BUDGET.CR_AMOUNT_06+BUDGET.CR_AMOUNT_07+BUDGET.CR_AMOUNT_08+BUDGET.CR_AMOUNT_09+BUDGET.CR_AMOUNT_10+BUDGET.CR_AMOUNT_11+BUDGET.CR_AMOUNT_12 AS ActvProj10
FROM BUDGET INNER JOIN ZBASED ON BUDGET.ACCOUNT=ZBASED.ACCOUNT
WHERE (((BUDGET.FISCAL_YEAR)=2010) And ((BUDGET.BUDGET_NBR)=6) And ((ZBASED.ACCT_UNIT)=BUDGET.ACCT_UNIT And (ZBASED.ACCT_UNIT)=[Cost Center]))
ORDER BY ZBASED.ACCOUNT;

qryBUD11

SELECT BUDGET.FISCAL_YEAR, BUDGET.BUDGET_NBR, BUDGET.ACCT_UNIT, BUDGET.ACCOUNT, ZBASED.ACCOUNT_DESC, BUDGET.DB_AMOUNT_01+BUDGET.DB_AMOUNT_02+BUDGET.DB_AMOUNT_03+BUDGET.DB_AMOUNT_04+BUDGET.DB_AMOUNT_05+BUDGET.DB_AMOUNT_06+BUDGET.DB_AMOUNT_07+BUDGET.DB_AMOUNT_08+BUDGET.DB_AMOUNT_09+BUDGET.DB_AMOUNT_10+BUDGET.DB_AMOUNT_11+BUDGET.DB_AMOUNT_12+BUDGET.CR_AMOUNT_01+BUDGET.CR_AMOUNT_02+BUDGET.CR_AMOUNT_03+BUDGET.CR_AMOUNT_04+BUDGET.CR_AMOUNT_05+BUDGET.CR_AMOUNT_06+BUDGET.CR_AMOUNT_07+BUDGET.CR_AMOUNT_08+BUDGET.CR_AMOUNT_09+BUDGET.CR_AMOUNT_10+BUDGET.CR_AMOUNT_11+BUDGET.CR_AMOUNT_12 AS Bud11
FROM BUDGET INNER JOIN ZBASED ON BUDGET.ACCOUNT = ZBASED.ACCOUNT
WHERE (((BUDGET.FISCAL_YEAR)=2011) AND ((BUDGET.BUDGET_NBR)=2) AND ((ZBASED.ACCT_UNIT)=[BUDGET].[ACCT_UNIT] And (ZBASED.ACCT_UNIT)=[Cost Center]))
ORDER BY ZBASED.ACCOUNT;

qryBUD10

SELECT BUDGET.FISCAL_YEAR, BUDGET.BUDGET_NBR, BUDGET.ACCT_UNIT, BUDGET.ACCOUNT, ZBASED.ACCOUNT_DESC, BUDGET.DB_AMOUNT_01+BUDGET.DB_AMOUNT_02+BUDGET.DB_AMOUNT_03+BUDGET.DB_AMOUNT_04+BUDGET.DB_AMOUNT_05+BUDGET.DB_AMOUNT_06+BUDGET.DB_AMOUNT_07+BUDGET.DB_AMOUNT_08+BUDGET.DB_AMOUNT_09+BUDGET.DB_AMOUNT_10+BUDGET.DB_AMOUNT_11+BUDGET.DB_AMOUNT_12+BUDGET.CR_AMOUNT_01+BUDGET.CR_AMOUNT_02+BUDGET.CR_AMOUNT_03+BUDGET.CR_AMOUNT_04+BUDGET.CR_AMOUNT_05+BUDGET.CR_AMOUNT_06+BUDGET.CR_AMOUNT_07+BUDGET.CR_AMOUNT_08+BUDGET.CR_AMOUNT_09+BUDGET.CR_AMOUNT_10+BUDGET.CR_AMOUNT_11+BUDGET.CR_AMOUNT_12 AS Bud10
FROM BUDGET INNER JOIN ZBASED ON BUDGET.ACCOUNT=ZBASED.ACCOUNT
WHERE (((BUDGET.FISCAL_YEAR)=2010) AND ((BUDGET.BUDGET_NBR)=1) AND ((ZBASED.ACCT_UNIT)=BUDGET.ACCT_UNIT) And ((ZBASED.ACCT_UNIT)=[Cost Center]))
ORDER BY ZBASED.ACCOUNT;

显然，我需要一个嵌套的SELECT ( SELECT中的SELECT)语句。有人能帮我吗？

在所有三个查询中，所选列、联接和order看起来都是相同的。唯一改变的是WHERE子句。所以也许你只需要把这三个条款放在一起..。

SELECT ...list of columns...
    FROM BUDGET INNER JOIN ZBASED ON BUDGET.ACCOUNT=ZBASED.ACCOUNT
WHERE (((BUDGET.FISCAL_YEAR)=2010) And ((BUDGET.BUDGET_NBR)=6) And ((ZBASED.ACCT_UNIT)=BUDGET.ACCT_UNIT And (ZBASED.ACCT_UNIT)=[Cost Center]))
OR (((BUDGET.FISCAL_YEAR)=2011) AND ((BUDGET.BUDGET_NBR)=2) AND ((ZBASED.ACCT_UNIT)=[BUDGET].[ACCT_UNIT] And (ZBASED.ACCT_UNIT)=[Cost Center]))
OR (((BUDGET.FISCAL_YEAR)=2010) AND ((BUDGET.BUDGET_NBR)=1) AND ((ZBASED.ACCT_UNIT)=BUDGET.ACCT_UNIT) And ((ZBASED.ACCT_UNIT)=[Cost Center]))
ORDER BY ZBASED.ACCOUNT

(给或拿一两个)。
