Question

我想使用以下语句

创建内联表值函数

    USE [abc]
    GO
    /****** Object:  UserDefinedFunction [dbo].[fnspEmpPeriodSkus]    Script Date: 04/14/2011 16:26:19 ******/
    SET ANSI_NULLS ON
    GO
    SET QUOTED_IDENTIFIER ON
    GO

    ALTER FUNCTION [dbo].[fnspEmpPeriodSkus] 
    (   
        -- Add the parameters for the function here
        @PositionID int
    )
    RETURNS TABLE 
    AS
    RETURN 
    (


declare @PeriodTypeID int
select @PeriodTypeID = cofig.PeriodTypeID from sysMarketSaleConfigurations config inner join setupJobs j on j.JobID = config.JobID
inner join setupDesignations d on d.JobID = j.JobID where d.DesignationID = @PositionID

SELECT EmployeeID,EmployeeName, ZoneID,Zone,RegionID,Region,TerritoryID,Territory,    StartDate, EndDate, empperiods.PeriodID, empperiods.DesignationID, EmpSkus.SKUID, EmpSkus.SKUCode, EmpSkus.Title, EmpSkus.GroupName, 
                                             EmpSkus.ProductGroupID, EmpSkus.PositionID,EmpSkus.PositionTitle 
FROM          (SELECT     StartDate, EndDate, PeriodID, DesignationID
                                                   FROM          (SELECT     sysPeriods.PeriodID, sysPeriods.StartDate, sysPeriods.EndDate, setupDesignations.DesignationID
                                                                           FROM          setupJobs INNER JOIN
                                                                                           setupDesignations ON setupJobs.JobID = setupDesignations.JobID CROSS JOIN
                                                                                           sysPeriods
                                                                           WHERE     Year(sysPeriods.StartDate) = Year(Current_timestamp) and (sysPeriods.PeriodTypeID = @PeriodTypeID)) AS drvtbl) AS empperiods LEFT OUTER JOIN
                                                      dbo.vwEmpSkus AS EmpSkus ON 
                                                  empperiods.DesignationID = EmpSkus.PositionID
    )

但它给了我以下错误：关键字声明附近的语法不正确。
问题：是否可以在内联表值函数中执行我想要做的事情（声明变量并使用函数参数从查询中获取结果）然后将此值传递给将要计算的主查询结果）？如果有，怎么样？如果没有什么是多语句表值选择函数或其他什么。我很欣赏建议和其他想法

Answer 1

不，您不能在内联表值函数中声明变量。

虽然您可以将2个查询合并为1 - 看起来您应该只能将该初始选择组合到当前使用该变量的子查询中。
