where子句分組依據中的SQL查詢

Question

我已經在Google上搜索了此內容，但仍然無法為我的問題找到正確的解決方案。

我想要的是在where子句的每個字段中獲取結果。 這是我的代碼：

BEGIN 
  -- INSERT INTO tmp_sr_accountsales (REFERENCENO, CUSTOMER, TransDate, SALESTYPE, STDTERMS, Amount)
  SELECT     act.referenceno, 
             act.customer, 
             act.atdate transdate, 
             act.salestype, 
             cust.stdterms, 
             Ifnull( act.totalamount, 0 )- Ifnull( act.discountamnt, 0 ) AS amount, 
             Ifnull( act.totalamount, 0 )- Ifnull( act.discountamnt, 0 ) AS amount2, 
             Ifnull( act.totalamount, 0 )- Ifnull( act.discountamnt, 0 ) AS amount3, 
             Ifnull( act.totalamount, 0 )- Ifnull( act.discountamnt, 0 ) AS amount4, 
             Ifnull( act.totalamount, 0 )- Ifnull( act.discountamnt, 0 ) AS amount5, 
             intyear                                                     AS intyear, 
             intyear1                                                    AS intyear2, 
             intyear2                                                    AS intyear3, 
             intyear3                                                    AS intyear4, 
             intyear4                                                    AS intyear5 
  FROM       100 _actual_transaction act 
  INNER JOIN 000 _customer cust 
  ON         ( 
                        act.customer = cust.customername ) 
  WHERE      ( 
                        act.referenceno IS NOT NULL 
             AND        act.customer LIKE thecustomer 
             AND        act.salestype LIKE thesalestype 
             AND       ( 
                                   year(act.atdate) IN( intyear, 
                                                       intyear1, 
                                                       intyear2, 
                                                       intyear3, 
                                                       intyear4 ) ) ); 

END;

如果可以看到代碼：

 WHERE
(
    act.REFERENCENO IS NOT NULL
    AND act.CUSTOMER LIKE theCustomer
    AND act.SALESTYPE LIKE theSalesType
    AND(
        YEAR(act.ATDATE) IN(
            intYear,
            intYear1,
            intYear2,
            intYear3,
            intYear4
        )
    )
);

在IN (intYear,intYear1,intYear2,intYear3,intYear4)內部的那個IN (intYear,intYear1,intYear2,intYear3,intYear4)它們具有不同的年份值。 我想得到每個人的結果。 是否有可能以1比1的方式獲得結果？ 因為該代碼的結果將僅添加該查詢中選擇的所有數據。

Answer 1

如果理解正確，則希望按年份對數據進行分組。 您可以嘗試此查詢。

   SELECT 
        act.REFERENCENO, 
        act.CUSTOMER, 
        act.ATDATE TransDate, 
        act.SALESTYPE, 
        cust.STDTERMS, 
        SUM(IFNULL(act.TOTALAMOUNT, 0) - IFNULL(act.DISCOUNTAMNT, 0)) AS Amount, 
        YEAR(act.ATDATE) AS intYear 
    FROM 100_actual_transaction act 
        INNER JOIN 000_customer cust ON (act.CUSTOMER = cust.CUSTOMERNAME)
    WHERE (act.REFERENCENO IS NOT NULL 
        AND act.CUSTOMER LIKE theCustomer 
        AND act.SALESTYPE LIKE theSalesType 
        AND (YEAR(act.ATDATE)IN (intYear,intYear1,intYear2,intYear3,intYear4)) );
    GROUP BY
        act.REFERENCENO, 
        act.CUSTOMER, 
        act.ATDATE TransDate, 
        act.SALESTYPE, 
        cust.STDTERMS,
        YEAR(act.ATDATE)

Answer 2

也許您需要做的就是一組工會？

  SELECT     intyear                                                    AS Yr,

一旦將數據“分解”為更多的行和更少的列，則可以對這些行使用GROUP BY和SUM（）來獲取“每年的值”
