内联表值函数sql server问题

我已经写了一个内联TVF，到目前为止我有这个。我收到此错误：结尾的语法不正确。有人可以为此建议解决方法。我是否可以通过语法方式实现，是否正确？

CREATE FUNCTION [hsip].[Question_Dtl_Table_Id]
(   
    -- Add the parameters for the function here
    @cRegion CHAR(2) ='00',
    @cState_Code CHAR(2) = '00',

正如Tim在评论中已经提到的，这不是内联表值函数，而是多语句表值函数。这里的不同之处在于性能。 MTVF通常比标量函数表现更差。但是，稍作修改即可轻松转换为ITVF。

CREATE FUNCTION [hsip].[Question_Dtl_Table_Id]
(   
    -- Add the parameters for the function here
    @cRegion CHAR(2) ='00',
    @cState_Code CHAR(2) = '00',
    @nFY NUMERIC(4,0) = 0,
    @nREPORT_ID NUMERIC(2,0) = 0,
    @nSECTION_ID NUMERIC(2,0) = 0,
    @nSUBSECTION_ID NUMERIC(2,0) = 0,
    @nDISPLAY_NUMBER NUMERIC(38,0) = 0,
    @nQUESTION_NUMBER NUMERIC(38,0) = 0,
    @nQUESTION_PART_NUMBER NUMERIC(38,0) = 0,
    @sUSER_ID VARCHAR(25) = NULL

) RETURNS TABLE AS RETURN 

    SELECT qi.REGION
        , qi.STATE_CODE
        , qi.FY
        , qi.REPORT_ID
        , qi.SECTION_ID
        , qi.SUBSECTION_ID
        , qi.DISPLAY_NUMBER
        , qi.QUESTION_NUMBER
        , qd.QUESTION_PART_NUMBER 
    from FY_ST_QUESTION_INFO qi
    inner join FY_ST_QUESTION_DETAIL qd on qi.FY_ST_QUESTION_INFO_TABLE_ID = qd.FY_ST_QUESTION_INFO_TABLE_ID
    where qi.region = @cRegion
        and qi.fy = @nFY
        and qi.REPORT_ID = @nREPORT_ID
        and qi.SECTION_ID = @nSECTION_ID
        and qi.SUBSECTION_ID = @nSUBSECTION_ID
        and qi.DISPLAY_NUMBER = @nDISPLAY_NUMBER
        and 
        (
            qi.REPORTER_ID = @sUSER_ID 
            or
            qi.DELEGATE_ID = @sUSER_ID 
            or
            qi.SUB_DELEGATE_ID = @sUSER_ID
        )

您需要为派生查询添加别名.. 

INSERT  INTO @tbl
                SELECT  *
                FROM    (SELECT 
                        ) AS T -- alias 
    ;

您的最外层选择是多余的，并且没有内部选择所需的别名。我不会添加别名，而是删除：

CREATE FUNCTION [hsip].[Question_Dtl_Table_Id]
(   
    -- Add the parameters for the function here
    @cRegion CHAR(2) ='00',
    @cState_Code CHAR(2) = '00',
    @nFY NUMERIC(4,0) = 0,
    @nREPORT_ID NUMERIC(2,0) = 0,
    @nSECTION_ID NUMERIC(2,0) = 0,
    @nSUBSECTION_ID NUMERIC(2,0) = 0,
    @nDISPLAY_NUMBER NUMERIC(38,0) = 0,
    @nQUESTION_NUMBER NUMERIC(38,0) = 0,
    @nQUESTION_PART_NUMBER NUMERIC(38,0) = 0,
    @sUSER_ID VARCHAR(25) = NULL

)
RETURNS @tbl TABLE ( Region CHAR(2),
    State_Code CHAR(2),
    FY NUMERIC(4,0),
    REPORT_ID NUMERIC(2,0),
    SECTION_ID NUMERIC(2,0),
    SUBSECTION_ID NUMERIC(2,0),
    DISPLAY_NUMBER NUMERIC(38,0),
    QUESTION_NUMBER NUMERIC(38,0),
    QUESTION_PART_NUMBER NUMERIC(38,0),
    USER_ID VARCHAR(25))

AS
--RETURN 
begin

INSERT INTO @tbl


SELECT
    qi.REGION, qi.STATE_CODE, qi.FY, qi.REPORT_ID, qi.SECTION_ID, qi.SUBSECTION_ID, qi.DISPLAY_NUMBER,
    qi.QUESTION_NUMBER, qd.QUESTION_PART_NUMBER
from 
    FY_ST_QUESTION_INFO qi
    inner join FY_ST_QUESTION_DETAIL qd
    on qi.FY_ST_QUESTION_INFO_TABLE_ID = qd.FY_ST_QUESTION_INFO_TABLE_ID
where
    qi.region= @cRegion
    and qi.fy= @nFY
    and qi.REPORT_ID = @nREPORT_ID
    and qi.SECTION_ID = @nSECTION_ID
    and qi.SUBSECTION_ID = @nSUBSECTION_ID
    and qi.DISPLAY_NUMBER =@nDISPLAY_NUMBER
    and (qi.REPORTER_ID = @sUSER_ID or
          qi.DELEGATE_ID= @sUSER_ID or
          qi.SUB_DELEGATE_ID = @sUSER_ID);
return;
end

但正如蒂姆评论的那样，这是一个多语句表值函数，但是因为你只是做一个选择，你可以像在线那样使它成为直线：

CREATE FUNCTION [hsip].[Question_Dtl_Table_Id]
(   
    -- Add the parameters for the function here
    @cRegion CHAR(2) ='00',
    @cState_Code CHAR(2) = '00',
    @nFY NUMERIC(4,0) = 0,
    @nREPORT_ID NUMERIC(2,0) = 0,
    @nSECTION_ID NUMERIC(2,0) = 0,
    @nSUBSECTION_ID NUMERIC(2,0) = 0,
    @nDISPLAY_NUMBER NUMERIC(38,0) = 0,
    @nQUESTION_NUMBER NUMERIC(38,0) = 0,
    @nQUESTION_PART_NUMBER NUMERIC(38,0) = 0,
    @sUSER_ID VARCHAR(25) = NULL

)
RETURNS TABLE
AS
RETURN
(
SELECT
    qi.REGION, qi.STATE_CODE, qi.FY, qi.REPORT_ID, qi.SECTION_ID, qi.SUBSECTION_ID, qi.DISPLAY_NUMBER,
    qi.QUESTION_NUMBER, qd.QUESTION_PART_NUMBER
from 
    FY_ST_QUESTION_INFO qi
    inner join FY_ST_QUESTION_DETAIL qd
    on qi.FY_ST_QUESTION_INFO_TABLE_ID = qd.FY_ST_QUESTION_INFO_TABLE_ID
where
    qi.region= @cRegion
    and qi.fy= @nFY
    and qi.REPORT_ID = @nREPORT_ID
    and qi.SECTION_ID = @nSECTION_ID
    and qi.SUBSECTION_ID = @nSUBSECTION_ID
    and qi.DISPLAY_NUMBER =@nDISPLAY_NUMBER
    and (qi.REPORTER_ID = @sUSER_ID or
          qi.DELEGATE_ID= @sUSER_ID or
          qi.SUB_DELEGATE_ID = @sUSER_ID)
