How to execute function in SQL Server 2008


Question

I build a function and I am trying to execute it...but some errors are occurring

CREATE FUNCTION dbo.Afisho_rankimin(@emri_rest int)
RETURNS int
AS
   BEGIN
       Declare @rankimi int
       Select @rankimi=dbo.RESTORANTET.Rankimi
       From RESTORANTET
       Where  [email protected]_rest
       RETURN @rankimi
  END
  GO
    SELECT dbo.Afisho_rankimin(5)AS Rankimi
  GO

The errors when I execute it are:

Msg 2714, Level 16, State 3, Procedure Afisho_rankimin, Line 11
There is already an object named 'Afisho_rankimin' in the database.

and also it is said that:

Can not find column "dbo", or the user defined function, or aggregate "dbo.Afisho_rankimin", or the name is ambiguous

I have come to this question and the one below several times.

how to call scalar function in sql server 2008

Each time, I try entering the Function using the syntax shown here in SQL Server Management Studio, or SSMS, to see the results, and each time I get the errors.

For me, that is because my result set is in tabular data format. Therefore, to see the results in SSMS, I have to call it like this:

SELECT * FROM dbo.Afisho_rankimin_TABLE(5);

I understand that the author's question involved a scalar function, so this answer is only to help others who come to StackOverflow often when they have a problem with a query (like me).

I hope this helps others.

you may be create function before so, update your function again using.

Alter FUNCTION dbo.Afisho_rankimin(@emri_rest int)
RETURNS int
AS
  BEGIN
     Declare @rankimi int
     Select @rankimi=dbo.RESTORANTET.Rankimi
     From RESTORANTET
     Where  [email protected]_rest
     RETURN @rankimi
END
GO

SELECT dbo.Afisho_rankimin(5) AS Rankimi
GO
