创建内联表值函数sql-server 2008

如何解决创建内联表值函数sql-server 2008

| 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,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做我想做的事情（声明一个变量并使用函数的参数从查询中获取结果）然后将该值传递给将计算结果的主查询）？如果是，怎么办？如果没有，则选择多语句表值函数是什么。我感谢建议和其他想法

解决方法

不，您不能在内联表值函数中声明变量。尽管您可以将2个查询合并为1个-看起来您应该能够将初始选择合并到当前使用该变量的子查询中。
