Declaring USER_NAME() as SQL Variable

Hi,

I have a User-defined function "Concatenate_NoteTexts" which I use in a
query (SQL Server 2000). On my local development machine it is called like
this:

SELECT
dbo.Concatenate_NoteTexts(Introducers.IntroducerID ) as NoteTexts
FROM tblIntroducers

I want to run the same code on a shared remote server where I am user "JON"
instead of "dbo". I don't want to hard-code the User Name into the SQL, but
when I tried to put the user name into a variable as here:

DECLARE @.USER_NAME VarChar(30)
SET @.USER_NAME = USER_NAME()

SELECT
@.USER_NAME.Concatenate_NoteTexts(Introducers.Intro ducerID) as NoteTexts
FROM tblIntroducers

I get the following error:

Server: Msg 170, Level 15, State 1, Line 4
Line 4: Incorrect syntax near '.'

Any advice?

TIA,

JON

Beg for your own database.
Development as a non-dbo is really a hastle.

You can have your own database without being a SystemAdministrator. Just
have a SystemAdministrator to run this code:

create database jon_dev
go
use jon_dev
go
sp_addalias 'jon', 'dbo'

David|||Hi David,

Thanks, nice idea, I'll have to see if the webhosts will do that.

But there must also be a way to code what I want *without* being a SysAd!

JON|||What are you trying to do with the variable? Concatenate? Or return it in
the select statement as a column? If the latter, change the period to a
comma.

DECLARE @.USER_NAME VarChar(30)
SET @.USER_NAME = USER_NAME()

SELECT
@.USER_NAME,Concatenate_NoteTexts(Introducers.Intro ducerID) as NoteTexts
FROM tblIntroducers

The question is slightly more interesting than it may look like.

Say that you instead had had a stored procedure, call it notetext_sp.
This would not have constituted any problem, because you could have
called it as:

EXEC notetext_sp

When you are logged in as JON on the remote server, SQL Server would
have found the notetext_sp owned by you. This works for any other
SQL Server object as well. Except scalar user-defined functions, because
you must refer to them with a two-part name. The reason for this is
syntactical, so that the parser can distinguish between UDF and built-in
functions.

However, there is an exception to the exception. This works:

ALTER FUNCTION nisse_fun (@.a int) returns varchar(90) as
BEGIN
RETURN (SELECT replicate('nisse', @.a))
END
go
declare @.g varchar(90)
exec @.g = nisse_fun 8
select @.g

That is you can invoke a scalar UDF with EXEC as well, and in this case
you don't need the two-part name. Whether this actually helps you, I
don't know.

However, as noted by David Browne, getting your database makes life a
lot easier.
