Question

我对我的生活似乎无法在我的用户定义表值函数的BEGIN语句附近看到语法错误。有人可以告诉我这里缺少的东西......

我每次修改语法时都会遇到同样的问题。

我几乎不知所措，我还有其他一些遵循相同语法的UDF，但无论出于何种原因，我都无法正确理解这一点。

尝试将您的功能更改为更像这样的功能。这比在这里循环更快。

CREATE FUNCTION F_I_SO_M2M_SOHEXFILT ()
RETURNS TABLE WITH SCHEMABINDING AS
 RETURN
WITH
    E1(N) AS (select 1 from (values (1),(1),(1),(1),(1),(1),(1),(1),(1),(1))dt(n)),
    E2(N) AS (SELECT 1 FROM E1 a, E1 b), --10E+2 or 100 rows
    E4(N) AS (SELECT 1 FROM E2 a, E2 b), --10E+4 or 10,000 rows max
    E6(N) as (select 1 from E4, E1), --100,000 rows
    cteTally(N) AS 
    (
        SELECT  ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) FROM E6
    ),
    FindTable as

        select N as IntFlag

您需要在声明中为表格命名

CREATE FUNCTION F_I_SO_M2M_SOHEXFILT ()
RETURNS @t TABLE (
