commands.
New Syntax:
SELECT TOP n * FROM tablename WHERE whereclause ORDER BY column(s)
Here is an example:
To show the top 5 bonuses where the bonus is under $500 from
SalesBonus table in ConComp:
SELECT TOP 5 * FROM SalesBonus WHERE Bonus < 500 ORDER BY Bonus=DESC
The "TOP n" goes between the word SELECT and the column list for the
command.
