Sql server Excel的参数化查询 更新：

我已设法使以下查询与Excel一起工作：

SELECT me.id ,me.merchant_num ,me.merchant_nm,
CASE WHEN me.status = 'A' THEN 'Yes' ELSE 'No' END AS production_mode,
Max(CASE WHEN tt.bank_txt = 'IBA' THEN tt.transaction_dt END) AS last_IBA_transaction_dt,
convert(bit, Substring(Max(convert(CHAR(8), tt.transaction_dt, 112) + convert(CHAR(1), trans_live)), 9, 1)) AS is_live
FROM Data.dbo.merchant_t me
LEFT JOIN Data.dbo.transaction_t AS tt
  ON tt.merchant_id = me.id 
where tt.transaction_dt >= ?
and tt.transaction_dt <= ?
and tt.trans_status = ? 
GROUP BY me.id,me.merchant_num,me.merchant_nm, me.status

显然，我需要以某种方式将这些日期参数化

结束更新 我有一个SQL server查询，如下所示：

WITH CTE_Merchants AS
(
    SELECT
        me.id, me.merchant_num, me.merchant_nm,
        COUNT(tt.id) as num_transactions,
        CASE 
           WHEN me.status = 'A' THEN 'Yes' 
           ELSE 'No' 
        END AS production_mode
    FROM
        merchant_t me
    LEFT OUTER JOIN 
        transaction_t tt ON tt.merchant_id = me.id 
                         AND tt.transaction_dt BETWEEN '2020-04-01' AND '2020-04-30' -- [PARAMETIZE BOTH DATES]
    WHERE 
        me.status = 'T' -- [PARAMETIZE]
    GROUP BY 
        me.id, me.merchant_num, me.merchant_nm, me.status
)
SELECT
    CTE_Merchants.id,
    CTE_Merchants.merchant_num,
    CTE_Merchants.merchant_nm,
    CTE_Merchants.num_transactions,
    CTE_Merchants.production_mode,
    A1.is_live,
    A2.last_IBA_transaction_dt
FROM
    CTE_Merchants
OUTER APPLY
    (SELECT TOP 1 transaction_t.trans_live AS is_live
     FROM transaction_t
     WHERE transaction_t.merchant_id = CTE_Merchants.id
     ORDER BY transaction_dt DESC) AS A1
OUTER APPLY
    (SELECT TOP 1 transaction_t.transaction_dt AS last_IBA_transaction_dt
     FROM transaction_t
     WHERE transaction_t.merchant_id = CTE_Merchants.id
       AND transaction_t.bank_txt = 'IBA'
     ORDER BY transaction_dt DESC) AS A2;

SELECT merchant_t.id
FROM XXX.dbo.merchant_t merchant_t
where start_dt = ?
and create_dt = ?
and status = ?

WITH
CTE_Merchants
AS
(
    SELECT distinct
        me.id, me.merchant_num, me.merchant_nm
        ,count(tt.id) as num_transactions
        ,CASE WHEN me.status = 'A' THEN 'Yes' ELSE 'No' END as production_mode
    FROM
        merchant_t me
        LEFT OUTER JOIN transaction_t tt
            ON  tt.merchant_id = me.id 
            AND (tt.transaction_dt >= ? and tt.transaction_dt <= ?)
    WHERE me.status = ?
    GROUP BY me.id, me.merchant_num, me.merchant_nm, me.status
)
SELECT
    CTE_Merchants.id
    ,CTE_Merchants.merchant_num
    ,CTE_Merchants.merchant_nm
    ,CTE_Merchants.num_transactions
    ,CTE_Merchants.production_mode
    ,A1.is_live
    ,A2.last_IBA_transaction_dt
FROM
    CTE_Merchants
    OUTER APPLY
    (
        select top 1
            transaction_t.trans_live AS is_live
        from transaction_t
        where
            transaction_t.merchant_id = CTE_Merchants.id
        order by transaction_dt desc
    ) AS A1
    OUTER APPLY
    (
        select top 1
            transaction_t.transaction_dt AS last_IBA_transaction_dt
        from transaction_t
        where
            transaction_t.merchant_id = CTE_Merchants.id
            and transaction_t.bank_txt = 'IBA'
        order by transaction_dt desc
    ) AS A2
;

我想在Excel电子表格中使用查询，我需要参数化查询注释中指示的变量

以下是Excel数据连接对话框：

问题是：当我尝试参数化变量时，例如更改

AND tt.transaction_dt BETWEEN '2020-04-01' and '2020-04-30'

到

我犯了一个错误

无效的参数号

接

无效的描述符索引

如果我将BETWEEN语句更改为

AND (tt.transaction_dt >= ? and  tt.transaction_dt <= ?)

然后，我将该查询替换为实际查询，我将其参数化如下：

WITH CTE_Merchants AS
(
    SELECT
        me.id, me.merchant_num, me.merchant_nm,
        COUNT(tt.id) as num_transactions,
        CASE 
           WHEN me.status = 'A' THEN 'Yes' 
           ELSE 'No' 
        END AS production_mode
    FROM
        merchant_t me
    LEFT OUTER JOIN 
        transaction_t tt ON tt.merchant_id = me.id 
                         AND tt.transaction_dt BETWEEN '2020-04-01' AND '2020-04-30' -- [PARAMETIZE BOTH DATES]
    WHERE 
        me.status = 'T' -- [PARAMETIZE]
    GROUP BY 
        me.id, me.merchant_num, me.merchant_nm, me.status
)
SELECT
    CTE_Merchants.id,
    CTE_Merchants.merchant_num,
    CTE_Merchants.merchant_nm,
    CTE_Merchants.num_transactions,
    CTE_Merchants.production_mode,
    A1.is_live,
    A2.last_IBA_transaction_dt

    CTE_Merchants

     FROM transaction_t
     WHERE transaction_t.merchant_id = CTE_Merchants.id
       AND transaction_t.bank_txt = 'IBA'
     ORDER BY transaction_dt DESC) AS A2;

SELECT merchant_t.id
FROM XXX.dbo.merchant_t merchant_t
where start_dt = ?
and create_dt = ?

WITH

    WHERE me.status = ?
    GROUP BY me.id, me.merchant_num, me.merchant_nm, me.status
)
SELECT
    CTE_Merchants.id
    ,CTE_Merchants.merchant_num
    ,CTE_Merchants.merchant_nm
    ,CTE_Merchants.num_transactions

            and transaction_t.bank_txt = 'IBA'
        order by transaction_dt desc
    ) AS A2

我得到的错误与以前完全相同。

请尝试像这样编辑您的查询

declare @dateFrom datetime = ?
declare @dateTo datetime = ?
declare @status varchar(20) = ?

WITH
CTE_Merchants
AS
(
    SELECT distinct
        me.id, me.merchant_num, me.merchant_nm
        ,count(tt.id) as num_transactions
        ,CASE WHEN me.status = 'A' THEN 'Yes' ELSE 'No' END as production_mode
    FROM
        merchant_t me
        LEFT OUTER JOIN transaction_t tt
            ON  tt.merchant_id = me.id 
            AND (tt.transaction_dt >= @dateFrom and tt.transaction_dt <= @dateTo)
    WHERE me.status = @status
    GROUP BY me.id, me.merchant_num, me.merchant_nm, me.status
)
SELECT
    CTE_Merchants.id
    ,CTE_Merchants.merchant_num
    ,CTE_Merchants.merchant_nm
    ,CTE_Merchants.num_transactions
    ,CTE_Merchants.production_mode
    ,A1.is_live
    ,A2.last_IBA_transaction_dt
FROM
    CTE_Merchants
    OUTER APPLY
    (
        select top 1
            transaction_t.trans_live AS is_live
        from transaction_t
        where
            transaction_t.merchant_id = CTE_Merchants.id
        order by transaction_dt desc
    ) AS A1
    OUTER APPLY
    (
        select top 1
            transaction_t.transaction_dt AS last_IBA_transaction_dt
        from transaction_t
        where
            transaction_t.merchant_id = CTE_Merchants.id
            and transaction_t.bank_txt = 'IBA'
        order by transaction_dt desc
    ) AS A2

我对Excel以及如何从Excel运行查询一无所知，但作为最后的手段，您可以尝试将复杂的查询包装到存储过程或表值函数中，然后从Excel调用它。像下面这样

此外，以过程/函数的形式为DB提供一个明确定义的接口是很好的，即使从技术上讲，您可以将复杂的查询直接放入Excel电子表格中。这将使维护代码和配置权限（如果需要）变得更容易。您可以授予Excel用户只执行此存储过程而不执行其他任何操作的权限，以便它们不会干扰数据库

存储过程

这就是从Excel中调用它的方式

EXEC [dbo].[ReadMerchants]
    @ParamStartDate = ?,
    @ParamEndDate = ?,
    @ParamStatus = ?

SELECT * FROM [dbo].[GetMerchants](?, ?, ?)

表值函数

这就是从Excel中调用它的方式

EXEC [dbo].[ReadMerchants]
    @ParamStartDate = ?,
    @ParamEndDate = ?,
    @ParamStatus = ?

SELECT * FROM [dbo].[GetMerchants](?, ?, ?)

显然，最好是显式列出所有列，而不是键入*

---

如果存储过程和表值函数都使用Excel，我个人会使用存储过程——如果需要，您可以将任何类型的复杂逻辑放入其中。功能更加有限。

您是否遵循了这些步骤？是的，我将用我尝试过的过程更新我的问题。Excel不允许在这种情况下使用参数？出去。您是否尝试在Excel中创建Select语句，然后按如下方式运行它，或者创建一个存储的ProcedureWITH关键字前必须加分号。

CREATE FUNCTION [dbo].[GetMerchants]
(
    @ParamStartDate date,
    @ParamEndDate date,
    @ParamStatus nvarchar(10)
)
RETURNS TABLE
AS
RETURN 
(
    -- Add the SELECT statement with parameter references here
    SELECT
    ...

)

SELECT * FROM [dbo].[GetMerchants](?, ?, ?)
