SQL這裏的語法有什麼問題？

這個函數的語法有什麼問題？我收到以下錯誤：SQL這裏的語法有什麼問題？

您正在嘗試使用語法的內聯表值函數時，你實際上有一個多語句表值函數。請參閱完整說明here。

您使用此：

--Transact-SQL Inline Table-Valued Function Syntax 
CREATE FUNCTION [ schema_name. ] function_name ([ { @parameter_name [ AS ] [ type_schema_name. ] parameter_data_type 
    [ =default ] [ READONLY ] } 
    [ ,...n ] 
    ] 
) 
RETURNS TABLE 
    [ WITH <function_option> [ ,...n ] ] 
    [ AS ] 
    RETURN [ (] select_stmt [) ] 
[ ; ]

，但你真的想這樣：

--Transact-SQL Multistatement Table-valued Function Syntax 
CREATE FUNCTION [ schema_name. ] function_name ([ { @parameter_name [ AS ] [ type_schema_name. ] parameter_data_type 
    [ =default ] [READONLY] } 
    [ ,...n ] 
    ] 
) 
RETURNS @return_variable TABLE <table_type_definition> 
    [ WITH <function_option> [ ,...n ] ] 
    [ AS ] 
    BEGIN 
     function_body 
     RETURN 
    END 
[ ; ]

現在說，函數中包含的Select語句不能將數據返回給客戶端。這是不正確末選擇具有這種* FROM @ TMP1 UNION SELECT * FROM @ TMP2 ORDER BY [rl_DisplayName] RETURN END – user380432 2010-09-28 17:43:32

你想'INSERT INTO @return_variable SELECT * FROM @ TMP1 UNION SELECT * FROM @ tmp2 ORDER BY [rl_DisplayName] RETURN END'。它是'@ return_variable'，用於將結果集傳回給調用者。 – 2010-09-28 18:11:07

當我現在改變它說不能改變'dbo.udf_ReportingLevelStructure2'，因爲它是一個不兼容的對象類型。 – user380432 2010-09-28 18:13:53

您的內聯表頭語法值函數

... 
RETURNS TABLE 
AS 
RETURN 
(
    SELECT .. FROM something WHERE ... 
) 
GO --end of function

你有一個多值表函數。

... 
RETURNS @result TABLE 
(
CompanyName VARCHAR(300), 
[rl_Index] INT, 
[rl_Addr1] VARCHAR(MAX), 
[rl_Addr2] VARCHAR(MAX), 
[rl_DisplayName] VARCHAR(MAX) 
); 
AS 
BEGIN 
... 
Do this 

Do that 

Data into @result 

END --of function 
GO

See MSDN for examples

現在說包含一個函數內不能將數據返回到客戶端Select語句。這是不正確的有這末尾SELECT * FROM @ tmp1 UNION SELECT * FROM @ tmp2 ORDER BY [rl_DisplayName]返回END – user380432 2010-09-28 17:57:03

當然。我的答案是「Data into @result」，MSDN的例子也是如此...... – gbn 2010-09-28 18:09:07

若要更改功能類型，你必須放棄功能，那麼只有你可以通過改變功能類型創造新型功能。

有三種類型的功能。

標量
內嵌表值
多聲明

ALTER不能用來改變功能類型。

您需要刪除並創建功能
