exec scaler-value function sql server 2005

You need to specify the schema name, eg:

select * from dbo.DistanceBetween

you must specify the objectowner whenver u calls a UDF

select * from dbo.DistanceBetween

If this is a scalar function (does not return a table) than you cannot include it in a FROM clause, but rather as part of the SELECT clause.  If on the other hand, it does in fact return a table than don't forget the parameters and user name as in:

select * from dbo.DistanceBetween(@Param1, @Param2, @Param3, @Param4)

Right, so I need to set it up as Table-value function then?

Here is my function as it is, which kind of function should I set it up as? I want to be able to call the function from a procedure then populate a temp table with the results, the function will be part of a loop. Knew I should have stuck to 2000.

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go


ALTER FUNCTION [dbo].[DistanceBetween] (@Lat1 as real,
                @Long1 as real, @Lat2 as real, @Long2 as real)
RETURNS real
AS
BEGIN

DECLARE @dLat1InRad as float(53);
SET @dLat1InRad = @Lat1 * (PI()/180.0);
DECLARE @dLong1InRad as float(53);
SET @dLong1InRad = @Long1 * (PI()/180.0);
DECLARE @dLat2InRad as float(53);
SET @dLat2InRad = @Lat2 * (PI()/180.0);
DECLARE @dLong2InRad as float(53);
SET @dLong2InRad = @Long2 * (PI()/180.0);

DECLARE @dLongitude as float(53);
SET @dLongitude = @dLong2InRad - @dLong1InRad;
DECLARE @dLatitude as float(53);
SET @dLatitude = @dLat2InRad - @dLat1InRad;
/* Intermediate result a. */
DECLARE @a as float(53);
SET @a = SQUARE (SIN (@dLatitude / 2.0)) + COS (@dLat1InRad)
                 * COS (@dLat2InRad)
                 * SQUARE(SIN (@dLongitude / 2.0));
/* Intermediate result c (great circle distance in Radians). */
DECLARE @c as real;
SET @c = 2.0 * ATN2 (SQRT (@a), SQRT (1.0 - @a));
DECLARE @kEarthRadius as real;
/* SET kEarthRadius = 3956.0 miles */
SET @kEarthRadius = 6376.5;        /* kms */

DECLARE @dDistance as real;
SET @dDistance = @kEarthRadius * @c;
return (@dDistance);
END

what excatly u r trying to do inside the fuction ?

Good stuff aneeshattingal, that got it, thanks everyone for the help.

By the way, the proc calculates the distance between four given points of latitude and longitude, so I pass in the values... Select dbo.DistanceBetween (57.135, -2.117, 57.138, -2.092) which will give me the distance between two different places on the planet, so long as you know the starting latitude, longitude and the ending latitude and longitude.
Good eh!
