Hye, there everyone, I'm new to everything here just need to that I have converted the following code into MS SQL SERVER 2008 from Oracle! Now it has some errors though I have done it and NEW to SQL SERVER 2008 Please correct my code;it has some errors! I don't know about how to get rid as I'm new! Please can somebody help me It will be a great effort like a teacher! I will be thankful! Thanks in advance...

if I were you I would do some google searching onthe known errors that you have. like how to create a SQL Server function first. maybe some SQL Server Syntax as well — Malachi, Aug 22 '13 at 18:31
I have been trying to plug in random numbers and I keep getting a Divide by Zero ERROR....lol — Malachi, Aug 22 '13 at 18:52
the question is tagged with the Oracle Tag and the SQL Server tag. and the code probably did work in Oracle at some point. Granted the user could have done more to bring the question closer to the right syntax, I kind of lean towards this being a review topic, but I am right on the line because the code had so many errors, it would almost be a good question for StackOverflow, but I fear that it would have received more down votes there than it did here. I agree that the code didn't even look like SQL Server. — Malachi, Aug 23 '13 at 13:34

first you should start with the basic structure of a Scalar Function

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

CREATE FUNCTION <Scalar_Function_Name, sysname, FunctionName> 
(
    -- Add the parameters for the function here
    <@Param1, sysname, @p1> <Data_Type_For_Param1, , int>
)
RETURNS <Function_Data_Type, ,int>
AS
BEGIN
-- Declare the return variable here
DECLARE <@ResultVar, sysname, @Result> <Function_Data_Type, ,int>

-- Add the T-SQL statements to compute the return value here
SELECT <@ResultVar, sysname, @Result> = <@Param1, sysname, @p1>

-- Return the result of the function
RETURN <@ResultVar, sysname, @Result>

END
GO

this is just the Template that SSMS gave me when I went to create a New Scalar Function.

Solution

I strongly suggest you do some research into using SQL Server Syntax a lot more

Here is what I came up with but I haven't tested it either.

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
-- =============================================
-- Author:      Name
-- Create date: 
-- Description: 
-- =============================================
CREATE FUNCTION FunctionName 
(
-- Add the parameters for the function here
@a1 INT,
@b1 INT,
@a2 INT,
@b2 INT
)
RETURNS int
AS
BEGIN
-- Declare the return variable here
DECLARE @Result int

DECLARE @tr1 INT;
   DECLARE @tr2 INT;
   DECLARE @tc1 INT;
   DECLARE @tc2 INT;
   DECLARE @ca1 INT;
   DECLARE @ca2 INT;
   DECLARE @cb1 INT;
   DECLARE @cb2 INT;
   DECLARE @xi INT;
   DECLARE @nt INT;

SET @tr1 = @a1+@b1
SET @tr2 = @a2+@b2
SET @tc1 = @a1+@a2
SET @tc2 = @b1+@b2
SET @nt = @tr1+@tr2
SET @ca1 =(@tc1/@nt*@tr1)
SET @ca2 =(@tc1/@nt*@tr2)
SET @cb1 =(@tc2/@nt*@tr1)
SET @cb2 =(@tc2/@nt*@tr2)
SET @xi =((power((@a1 -@ca1),2)/@ca1)+(power((@a2 -@ca2),2)/@ca2)+(power((@b1 -@cb1),2)/@cb1)+(power((@b2-@cb2),2)/@cb2))

-- Add the T-SQL statements to compute the return value here
SELECT @Result = @xi

-- Return the result of the function
RETURN @Result

END
GO

all of your Variables need to have @ at the beginning of them.

and from the example you can sort of see the syntax for declaring the variables.
