Question

What is wrong with the syntax in this function? I am getting the following errors:

Answer 1

You're trying to use the syntax for a inline table-valued function when you actually have a multi-statement table-valued function. See the full description here.
You're using this:
--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 [ ) ]
[ ; ]
BUT, you really want this:
--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

To change function type you must have to drop function and then only you can change function type by creating new type function.
There are three types of functions.
Scalar
Inline table valued
Multi Statement
ALTER cannot be used to change the function type.
You need to DROP and CREATE the function

Answer 3

Your header syntax for inline table valued functions
...
RETURNS TABLE
AS
RETURN
(
SELECT .. FROM something WHERE ...
)
GO --end of function
You have a multi-valued table function.
...
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 4

Just Drop and Create your SQL statement
