数据的分多次插入临时表操作

来源：互联网发布：编程小白编辑：程序博客网时间：2024/05/16 10:41

不知道大家遇到过没有，在过滤数据的时候，往往要把数据分好几次的插入到临时表中，而有时会发现第二次插入数据到临时表时，会报
仅当使用了列列表并且 IDENTITY_INSERT 为 ON 时，才能为表'card'中的标识列指定显式值，这样的错误。所以我把自己遇到的问题记录了下来，并解决了。以下是我解决后的源码：

ALTER PROC [dbo].[BeforePaymentC]
@eccUser int,
@wher    varchar(2000)=''
AS
BEGIN
    DECLARE @eccCode VARCHAR(8000)
    DECLARE @ii        INT
    SET @eccCode=''
    SET @ii=1

    SELECT @eccCode=ISNULL(@eccCode,'')+CONVERT(VARCHAR(20),id)+',' FROM dbo.eccCollCard WHERE eccUser =@eccUser AND eccStatu=2
    IF @eccCode<>''
        BEGIN
            SET @eccCode=SUBSTRING(@eccCode,0,LEN(@eccCode))
            IF EXISTS(SELECT * FROM sysobjects WHERE NAME='#ttemp')
                DROP TABLE #ttemp

            --组装临时数据
            WHILE @ii<=dbo.Get_StrArrayLength(@eccCode,',')
                BEGIN
                    IF @ii=1
                        BEGIN
                            SELECT * INTO #ttemp   FROM dbo.eccGoods WHERE ecgCK=dbo.Get_StrArrayStrOfIndex(@eccCode,',',@ii)
                                                                AND NOT EXISTS(SELECT *FROM eccPayment WHERE id=ecgXS and ecpStatu in(0,1))
                            SET IDENTITY_INSERT #ttemp ON
                        END
                    ELSE
                        BEGIN
                            INSERT INTO #ttemp (id,ecgCardCode,ecgStatus,ecgType,ecgInUser,ecgInDate,ecgChkInUser,ecgChkInDate,ecgGetUser,
                                                ecgGetDate,ecgGetUser2,ecgGetDate2,ecgSale,ecgSalePrice,ecgUpPrice,ecgSaleDate,ecgPerid,ecgGetType,
                                                ecgYearCard,ecgGoCar,ecgGoActDate,ecgPassWord,ecgGoUN,ecgGoMobi,ecgRC,ecgCK,
                                                ecgXS,ecgStatu,ecgInterPrice) SELECT id,ecgCardCode,ecgStatus,ecgType,ecgInUser,ecgInDate,ecgChkInUser,ecgChkInDate,ecgGetUser,
                                                ecgGetDate,ecgGetUser2,ecgGetDate2,ecgSale,ecgSalePrice,ecgUpPrice,ecgSaleDate,ecgPerid,ecgGetType,
                                                ecgYearCard,ecgGoCar,ecgGoActDate,ecgPassWord,ecgGoUN,ecgGoMobi,ecgRC,ecgCK,
                                                ecgXS,ecgStatu,ecgInterPrice FROM dbo.eccGoods WHERE ecgCK=dbo.Get_StrArrayStrOfIndex(@eccCode,',',@ii)
                                                                                AND NOT EXISTS(SELECT *FROM eccPayment WHERE id=ecgXS and ecpStatu in(0,1))
                        END
                    SET @ii=@ii+1
                END
            IF @eccCode<>''
                BEGIN
                    SET IDENTITY_INSERT #ttemp OFF
                    IF @wher='' OR @wher IS NULL OR LEN(@wher)=0
                        SELECT *FROM #ttemp
                    ELSE
                        EXEC('SELECT *FROM #ttemp   WHERE '+ @wher)
                END
        END
END
