I am getting an error when trying to get this table valued function up. I have an error when I try to modify it. It is

Incorrect syntax near the keyword 'Declare'.

However when I use this outside of the function it all works great. So I was just wondering is there something I am missing or how should I be doing this. Thanks.

When you're using multiple statements in a function and returning a table, i.e. a Table-Valued User-Defined Function, you need a certain syntax, something like:

CREATE FUNCTION dbo.MyFunction(@ID int)
RETURNS @Mytable TABLE 
(
    -- Columns returned by the function
    ID int PRIMARY KEY NOT NULL, 
    -- (Other columns as required)
)
AS
BEGIN

  --Various statements to populate @Mytable

  RETURN; -- Returns @Mytable
END

See Table-Valued User-Defined Functions for more information.

If you have a function that just has RETURNS TABLE with no definition of the table being returned, this is an Inline User-Defined Function.

Inline user-defined functions are a subset of user-defined functions that return a table data type. Inline functions can be used to achieve the functionality of parameterized views.

See Inline User-Defined Functions.

The syntax for this is like:

CREATE FUNCTION dbo.MyFunction(@ID int)
RETURNS TABLE 
AS
RETURN
(
  SELECT *
  FROM MyTable
  WHERE ID = @ID
);

Here you don't define the table being returned and the body of the function can only be one SELECT statement.

At the moment your code is somewhere between the two; you need to get this to work as the first option, i.e. the Table-Valued User-Defined Function; start by defining the table being returned in the RETURNS clause and go from there.

You have invalid function declaration. When returning table you should specify variable name that will hold your table, so your header may look like:

ALTER FUNCTION [dbo].[XXX](.....)
RETURNS @temp TABLE (contactkey int, contactkey1 int, rolekey1 int,contactkey2 int, rolekey2 int, relationshipid int) 
AS 
begin
...

You need to define the table's columns in the RETURNS statement.
