Here is my scenario: Have records in a table, want to send email, using xp_sendmail, have to pull the lowest recordnumber from the table and set that equal to @emid, then loop through, and send the records. I'm getting a syntax error using keyword TOP, here is the query. I appreciate all assistance in advance, thanks mj.

declare @EMid int
select @emid = top 1 SampleRequestID from dbo.vSampleRequest order by SampleRequestID asc
--print @emid
While (Select email From Dbo.vSampleRequest Where (SampleRequestID = @EmID)) is not null
begin SELECT * from Dbo.vSampleRequest
Where SampleRequestID = @emid
EXEC master..xp_sendmail @recipients ='jordan_murphy@core.com',
@message = 'test of Sp', @Subject = 'Sample Request Email'
--print @emid
set
@emid = @emid + 1

end
GO

Pronoun trouble...

Try this..


USE Northwind
GO

 DECLARE @EMid int

  SELECT TOP 1 @EMid = OrderId 
    FROM Orders 
ORDER BY OrderId

  SELECT TOP 1 OrderId 
    FROM Orders 
ORDER BY OrderId

SELECT @EMid

SELECT @@POST FROM Brain ORDER BY NewId()

That's correct! It's an AlphaNumeric!

I think, this will be faster.

USE Northwind
GO
DECLARE @EMid int
SELECT @EMid = min(Orderid) FROM Orders

Did I mention (today?) that I hate TOP...

Anyway...the execution plan adds an extra step to the MIN code...

Doing stream aggregates...

The Traces are identical...but it's not a lot of data...
