SET ROWCOUNT

If your queries make use of the SQL Server SET_ROWCOUNT clause, you can use the TOP clause instead. For example, the following code snippet:

SET ROWCOUNT @N;
SELECT foo
FROM   bar;

Can be replaced with the following syntax:

SELECT TOP (@N) foo
FROM   bar;

You can also use TOP to replace SET ROWCOUNT in ad hoc queries; for example, in a DELETE statement:

DELETE TOP (@N) FROM table [WHERE condition];

Similarly, you can use TOP in an UPGRADE statement:

UPDATE TOP (@N) table SET field = value

Unlike TOP, the SET ROWCOUNT clause persists for the life of a connection; to return a complete result set after using SET ROWCOUNT, you must reset the rowcount to 0. If you are using TOP as a replacement for SET ROWCOUNT, note that you must specify TOP each time you wish to limit the number of rows in a query.
