SQL 2005 testing

I've begun some testing with the June beta of SQL 2005. One problem
I've hit is with scalar-valued functions. The error I often get when
executing functions is "Select statements included within a function
cannot return data to a client.". These same functions are working
fine under SQL 2000.

Has anybody seen this behavior or know what the deal is?

Doesn't a SELECT inside of a routine return a result set to the caller?
What would be the effect of doing this inside, say, a function in a
WHERE clause. You may want to assign the result of that select to a
local variable...

Serge,
Yes, I do assign the results of the select to a local variable. These
functions are simple and I'm not having trouble with how to use
functions. The problem is they work with SQL 2000 but produce errors
with SQL 2005. Here is an example of one of the functions.

create function dbo. vfVendorName(@Subscr
iberID int, @ApplicationNum
int)
returns varchar(100)
as
BEGIN
declare @rtn varchar(100)
select @rtn=Vendorname from vAppVendor
where SubscriberID=@Subscr
iberID and ApplicationNum=@Appl
icationNum
return @rtn
end

Works fine when called from SQL 2000 but gives "Select statements
included within a function cannot return data to a client." when run
from SQL 2005.

Inside a function you are not permitted to execute a SELECT statement that
returns data to the client. Could you post an example of a function that
returns this error in SQL2005 but not in SQL2000.

I rewrote your function as:

create function dbo.blafs(@OrderID int, @EmployeeID int)
returns varchar(100)
as
BEGIN
declare @rtn nvarchar(100)
select @rtn = CustomerID from Northwind..Orders
where OrderID = @OrderID and EmployeeID = @EmployeeID
return @rtn
end
go
SELECT dbo.blafs (10988, 3)
go

Since I only changed table and column names to a database that I have
available, this function should yield the same result as yours. However,
I seem to recall that I have seen a similar problem discussed in the
beta newsgroups, so there might be an issue somewhere.

Anyway, this is not the place where you should discuss SQL 2005.
Please see http://go.microsoft.com/fwlink/?linkid=31765 for access
information to the beta newsgroups for SQL 2005. This is because
these groups are frequented by more SQL Server developers than
this newsgroup.

Erland,
Thanks for pointing me to correct newsgroup. I'll post my issue there.
I do believe this is an issue with sql 2005 as I have several
functions which do the same type of retrieval - some work and some
don't, yet they all work fine on sql 2000
