在虚拟表错误中使用Sql函数

Erorr消息

Msg 319，15级，状态1，程序Get_LogoFaturaIskonto，第11行

---

关键字“with”附近的语法不正确。如果此语句是公共表表达式、xmlnamespaces子句或更改跟踪上下文子句，则前一语句必须以分号终止。

至少在缺少分号时：

        CREATE FUNCTION dbo.Get_LogoFaturaIskonto (
        @InvoiceRef     int = 0,
        @ParentlnRef    int = 0,
        @Rownumber      int = 0
    )
    RETURNS decimal(18,2)
    AS
    BEGIN
        DECLARE @VALUE decimal(18,2)
        WITH NEWTABLE AS 
        (SELECT ROW_NUMBER() OVER(ORDER BY LOGICALREF ASC) AS ROWNUMBER#
      ,DISCPER,LOGICALREF,INVOICEREF,PARENTLNREF FROM dbo.LG_002_01_STLINE 
    WHERE 
       INVOICEREF = @InvoiceRef AND PARENTLNREF = @ParentlnRef AND LINETYPE = 2)
        SELECT @VALUE = (SELECT * FROM NEWTABLE WHERE ROWNUMBER = @Rownumber)
        RETURN ISNULL(@VALUE,0)
    END

错误消息是自解释的，即使错误消息中建议了解决方案，您尝试过吗？顺便说一下，

SELECT@VALUE=（SELECT*FROM…

也会给出错误，因为

NEWTABLE

包含多个列。

CREATE FUNCTION dbo.Get_LogoFaturaIskonto (
    @InvoiceRef     int = 0,
    @ParentlnRef    int = 0,
    @Rownumber      int = 0
)
RETURNS decimal(18,2)
AS
BEGIN
    DECLARE @VALUE decimal(18,2);

    WITH NEWTABLE AS 
    (SELECT ROW_NUMBER() OVER(ORDER BY LOGICALREF ASC) AS ROWNUMBER#
  ,DISCPER,LOGICALREF,INVOICEREF,PARENTLNREF FROM dbo.LG_002_01_STLINE 
WHERE 
   INVOICEREF = @InvoiceRef AND PARENTLNREF = @ParentlnRef AND LINETYPE = 2)
    SELECT @VALUE = (SELECT * FROM NEWTABLE WHERE ROWNUMBER = @Rownumber)
    RETURN ISNULL(@VALUE,0)
END
