select top query

In you are using SQL Server 2000 then this is not possible.

I suspect you are in sql server 2000, which will not accept a parameter for the top clause. In 2005 it would work. You need to create and execute the sql dynamically for it to work in 2000.

in sql server 2000 try create procedure ss(@s int) as SET ROWCOUNT @s select sno from summa1 order by newid SET ROWCOUNT 0 ROWCOUNT should turn pink..i havnt used it in a while so i may have typed it wrong. I do not believe that Rowcount is available in sql server 2k5, it was replaced with something but i dont remember what. EDIT: ROWCOUNT is the correct one..@@ROWCOUNT wont work. you could also use dynamic sql like EXEC 'SELECT TOP ' + CAST(@s AS CHAR) + ' sno FROM summa1 ORDER BY newid'

You can use SET @@rowcount or create procedure ss(@s int) as EXEC 'select top ' + CAST(@s AS CHAR) + ' sno from summa1 order by newid()'

I don't think this would work, I'm pretty sure @@rowcount is read only. I don't have sql server 2000 installed, but I have never seen @@rowcount being set, only ever read. What I think is meant is set rowcount, but this cannot be set to a parameter, so you are back to dynamic sql

Both rowcount (to set the number of rows returned) and @@rowcount (the number of rows affected) are both still alive and kicking in SQL Server 2005

It works fine i have it done in multiple places mostly in stored procedures, and in some other queries. SET ROWCOUNT it works well for randomizing the data you pull from a table with no PK. @@ROWCOUNT might be read only, ROWCOUNT is the correct one to use.

Sorry, you can set rowcount to a parameter, I just couldn't type when I tried it :-O

I'm pretty sure you're thinking of SET ROWCOUNT and not SET @@ROWCOUNT. @@ROWCOUNT tells you how many rows were affected by a statement.

Deja View - the feeling that you've seen this post before.

Although be aware that as far as I know, ROWCOUNT is being deprecated in 2K5 and it is removed from SQL Server 2K8 (or perhaps the one after 2K8)
