Answer 1

Vous essayez d'utiliser la syntaxe pour une fonction de table inline lorsque vous avez en fait une fonction table multi-instruction. Voir la description complète here.

Vous utilisez ceci:

--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 [) ] 
[ ; ] 

MAIS, vous voulez vraiment ceci:

--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 
[ ; ] 

Answer 2

Votre syntaxe d'en-tête pour la table en ligne les fonctions d'une valeur

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

Vous avez une fonction table à plusieurs valeurs.

... 
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

Answer 3

Pour changer le type de fonction, vous devez avoir à abandonner la fonction et alors seulement vous pouvez modifier le type de fonction par créer une nouvelle fonction de type.

Il existe trois types de fonctions.

• Scalar
• Table Inline
évalués
• Déclaration multi

ne peut pas être ALTER utilisé pour modifier le type de fonction.

Vous devez DROP et créer la fonction

Answer 4

Il suffit de déposer et créez votre instruction SQL
