Hello

I have reported this bug previosly, but Microsoft has so far not responded yet, so I am reporting it again. Basicly, SET FMTONLY is NOT working correctly with SQL Server 2000. Because of this bug I still have to use SQL Server 7.0 for my campuswide student information system application, although I really would like to upgrade to SQL Server 2000 :-

Here's the script to reproduce the bug

-- create the test tables, and populate the
Create Table dbo.USERS_TES
([USER_ID] int PRIMARY KEY not null
[NAME] varchar(20) null

/*Hi Bulent, while I am certainly not going to dispute that the
behaviour using this command in SQL 7 does do what you expect (since I
cant test it against 7 at the mo), I think this behaviour in 2000 is by
design.

As you know the SET FMTONLY ON setting is telling SQL to return only
the metadata of a result set. It appears that all statements that do
not return a result set and metadata are processed only but then
ignored (if that makes sense! since you have effectively told SQL that
you are only interested in the metadata) INCLUDING logic statements.

See the following*/


USE Northwind
SET NOCOUNT OFF
DECLARE @myInt TINYINT
SET @myInt=1
--SET FMTONLY ON
PRINT 'Display this text from print. You will see it does not print'
SELECT 'Display this text from select. You will see it is processed BUT
the result set contains no metadata'
SELECT @myInt=2 --You will see below (from print) that this select is
processed
SET FMTONLY OFF PRINT @myInt SET FMTONLY ON
SET @myInt=3 --You will see below (from print) that this set is
processed
SET FMTONLY OFF PRINT @myInt SET FMTONLY ON
select * from northwind..orders
select * from northwind..[order Details]
IF @myInt=1 --is skipped
select * from northwind..orders --meta is returned
ELSE --is skipped
select * from northwind..[order Details] --meta is returned
ENDIF
EXEC SP_HELP --Stored procedure with multiple Selects including
variable assignments all metadata selects are returned
SELECT * FROM Northwind..Invoices --This is a view, metadata is returned
SET FMTONLY OFF
