To limit the number of rows returned in a MS SQL query you need to use the TOP command. This goes before you name the columns that are to be returned by the SELECT statement.

The following query returns the first 35 rows from a table.

SELECT TOP 35 * FROM table WHERE value > 4 ORDER BY id DESC

To get a random row from a Microsoft SQL database you need to use the NEWID() function. This will generate a new random number for each row and order them by that new number. This is used in conjunction with the TOP clause to limit the amount of returned rows to one.
SELECT TOP 1 value FROM table ORDER BY NEWID()
