Hi,
SELECT [FIRST n] [SKIP n] ....
For example : SELECT FIRST 5 * FROM TableX
This returns the first 5 records from the select statement.
like SQL-92, SQL-2000
Here is a little paste from the SQL-92 standard :

SELECT [FIRST n] [SKIP n] ....
For example : SELECT FIRST 5 * FROM TableX
This returns the first 5 records from the select statement.
