Question

我有一个任务要向查询发送一个成本中心列表（varchar），该查询应根据每个输入提供数据。

我对动态SQL不了解。

所以我有一个成本中心列表，例如88115100，88115200，88115300 ......大约30。

declare @month integer

declare @month_2 integer
declare @startdate datetime
declare @enddate datetime
declare @costcenter varchar(20)

set @month_2= 3--/* t3.finncPriod=*/ '[%0]'
set @month=@month_2-1
set @costcenter='88115100'
set @startdate= '03/01/2019'--/*t0.docdate from oinm t0 where t0.docdate>=*/'[%1]'
set @enddate= '03/31/2019'--/*t0.docdate from oinm t0 where t0.docdate>=*/'[%2]'

select * from
(
    select
        t0.name+'-Budget' as 'toPivot',
        t4.AcctCode as 'GLAccount',
        t4.AcctName,
        isnull(t2.DebLTotal,0) as 'value' 
    from obgs as t0 
    inner join obgt as t1 on t0.AbsId = t1.Instance
    inner join bgt1 as t2
        on t2.Instance = t1.Instance
        and t2.AcctCode = t1.AcctCode
        and t2.Line_ID = @month
    inner join oact as t4 on t4.AcctCode = t2.AcctCode
    where t0.name = @costcenter 

    union all 

    select
        t0.name + '-Actual'as 't0Pivot',
        t4.AcctCode as 'GLAccount',
        t4.AcctName,
        isnull(sum(debit-credit),0) as 'value'
        from jdt1 as t3 
    left join oact t4 on t4.AcctCode = t3.Account
    left join obgs t0 on t0.Name = t3.ProfitCode
    left join obgt t1
        on t1.Instance = t0.AbsId
        and t4.AcctCode = t1.AcctCode
    left join bgt1 as t2
    on t1.Instance = t2.Instance
    and t2.AcctCode = t1.AcctCode
    and t2.line_ID = 2
    where
        t3.refdate between @startdate and @enddate
        and t4.ExportCode is not null
        and t0.name = @costcenter
    group by
        t0.name,
        t4.AcctCode,
        t4.AcctName

) as a
pivot 
(
    sum(a.value)
    for a.topivot in
    ([88115100-Budget], [88115100-Actual])
)
as pivottable

好吧，据我所知，您可能想要stored procedure，并且您建议它可以/应该是动态SQL。现在，您可以做到这一点，但是唯一需要动态SQL的地方是必须根据变量重写关键字。您必须使用上面的代码来执行此操作-特别是以下代码：

pivot 
(
    sum(a.value)
    for a.topivot in
    ([88115100-Budget], [88115100-Actual])
)

这是因为[88115100-Budget]和[88115100-Actual]是取决于变量（@costcenter）的关键字。但是，没有理由让它们在SQL中这样命名！最好以后再使用这些名称，无论将数据发送到SQL外部是什么。

相反，您可能需要类似以下代码的内容：

CREATE PROCEDURE GetBudgetForCostCenter
    @month integer = 2,
    @month_2 integer = 3,
    @startdate datetime = '03/01/2019',
    @enddate datetime = '03/31/2019',
    @costcenter varchar(20) = '88115100'
    --you probably don't actually want the default values in here, but I've left them for demonstration.
AS
BEGIN
    select * from
    (
        select
            'Budget' as 'toPivot',
            t4.AcctCode as 'GLAccount',
            t4.AcctName,
            isnull(t2.DebLTotal,0) as 'value' 
        from obgs as t0 
        inner join obgt as t1 on t0.AbsId = t1.Instance
        inner join bgt1 as t2
            on t2.Instance = t1.Instance
            and t2.AcctCode = t1.AcctCode
            and t2.Line_ID = @month
        inner join oact as t4 on t4.AcctCode = t2.AcctCode
        where t0.name = @costcenter 

        union all 

        select
            'Actual'as 't0Pivot',
            t4.AcctCode as 'GLAccount',
            t4.AcctName,
            isnull(sum(debit-credit),0) as 'value'
            from jdt1 as t3 
        left join oact t4 on t4.AcctCode = t3.Account
        left join obgs t0 on t0.Name = t3.ProfitCode
        left join obgt t1
            on t1.Instance = t0.AbsId
            and t4.AcctCode = t1.AcctCode
        left join bgt1 as t2
        on t1.Instance = t2.Instance
        and t2.AcctCode = t1.AcctCode
        and t2.line_ID = 2
        where
            t3.refdate between @startdate and @enddate
            and t4.ExportCode is not null
            and t0.name = @costcenter
        group by
            t0.name,
            t4.AcctCode,
            t4.AcctName

    ) as a
    pivot 
    (
        sum(a.value)
        for a.topivot in
        ([Budget], [Actual])
    )
    as pivottable
END

请注意，我已将您的列从88115100-Budget和88115100-Actual更改为Budget和Actual。这意味着您可以避免使用动态SQL，这是您应该始终要实现的目标。

现在应该可以通过类似的方式调用

exec GetBudgetForCostCenter @month = 2, @month_2 = 3, @startdate = '03/01/2019', @enddate = '03/31/2019', @costcenter = '88115100'

免责声明：我不会比使用内置语法突出显示测试语法更多的麻烦，因为它将需要创建一个新的数据库和许多新的对象，因此，如果其中有任何错别字，就对不起。
