Question

我正在使用Entity Framework Reverse POCO Generator 2.19.0来处理现有数据库

一切都很好，直到我添加一个从多个表（包括时间表）执行SELECT的sproc，我希望工具（POCO Generator）生成一个Entity来存储来自该sproc的返回值，但它只是生成一个函数返回Int而不是预期的对象。

我应该如何构建sproc或poco生成器期望的SELECT类型？

这是程序

CREATE PROCEDURE [dbo].[GetAccountStatement] --Historial de transacciones
@MembershipID BIGINT
, @pagina INT = 1
, @npag INT = 100
AS
DECLARE @sql NVARCHAR(MAX),
        @offset INT,
        @NumeroTransacciones BIGINT,
        @AccountID BIGINT

SELECT
    @offset = (@pagina - 1) * @npag

SET FMTONLY OFF

SELECT
    transactionCheck_Rel.CheckID,
    AmountTotal AS Accrual,
    0 AS Redemption INTO #TransactionAux_t4
FROM transactionCheck_Rel
JOIN [transaction]
    ON [transaction].TransactionID = transactionCheck_Rel.TransactionID
    AND TransactionTypeID = 4

SELECT
    transactionCheck_Rel.CheckID,
    0 AS Accrual,
    AmountTotal AS Redemption INTO #TransactionAux_t3
FROM transactionCheck_Rel
JOIN [transaction]
    ON [transaction].TransactionID = transactionCheck_Rel.TransactionID
    AND TransactionTypeID = 3


SELECT
    #TransactionAux_t4.CheckID,
    #TransactionAux_t4.Accrual,
    ISNULL(#TransactionAux_t3.redemption, 0) AS redemption INTO #TransactionAux
FROM #TransactionAux_t4
LEFT JOIN #TransactionAux_t3
    ON #TransactionAux_t3.CheckID = #TransactionAux_t4.CheckID
ORDER BY #TransactionAux_t4.CheckID

INSERT INTO #TransactionAux
    SELECT
        #TransactionAux_t3.CheckID,
        #TransactionAux_t3.Accrual,
        ISNULL(#TransactionAux_t3.redemption, 0) AS redemption
    FROM #TransactionAux_t3

SELECT
    #TransactionAux.CheckID,
    [dbo].[check].StoreID,
    store.SystemName,
    dbo.[check].NetAmount,
    account.AccountID,
    #TransactionAux.Accrual,
    #TransactionAux.redemption,
    account.InitialBalance,
    account.FinalBalance,
    dbo.[transaction].TransactionID,
    dbo.[transaction].BusinessDate,
    dbo.membershipAccount_Rel.MembershipID

FROM dbo.account
LEFT JOIN dbo.assignCheck
    ON assignCheck.AccountID = account.AccountID
LEFT JOIN [dbo].[check]
    ON [check].CheckID = assignCheck.CheckID
LEFT JOIN #TransactionAux
    ON #TransactionAux.CheckID = [check].CheckID
JOIN dbo.[transaction]
    ON [transaction].AccountID = account.AccountID
JOIN dbo.transactionDetail
    ON transactionDetail.TransactionID = [transaction].TransactionID
LEFT JOIN transactionCheck_Rel
    ON transactionCheck_Rel.TransactionID = [transaction].TransactionID
LEFT JOIN dbo.store
    ON store.StoreID = [check].StoreID
JOIN dbo.membershipAccount_Rel
    ON membershipAccount_Rel.AccountID = account.AccountID
ORDER BY membershipAccount_Rel.MembershipID ASC OFFSET @offset ROWS FETCH NEXT @npag ROWS ONLY

反向POCO生成器的作者Simon Hughes在discussion forum for the project中说明了对这个问题的回答。

问题：

“我在存储的PRoc中使用临时表。但是类不是由于在SP“
中使用此临时表而生成

回答：

“发电机无法做任何事情。但你可以做的是将存储过程更改为表值函数，和定义要返回的表。我相信我最近提到过这个某处并举了一个例子。“

我进一步浏览了讨论论坛，但尚未找到他所引用的例子。你可能最好直接在该论坛上提问。我以前曾在那里提过问题，西蒙非常敏感。

此SO post也可能有所帮助。
