Returning only the first N records in a SQL query differs quite a bit between database platforms. Here's some samples:

Microsoft SQL Server

SELECT TOP 10 column FROM table
PostgreSQL and MySQL

SELECT column FROM table
LIMIT 10
Oracle

There are lots of ways to select a random record or row from a database table. Here are some example SQL statements that don't require additional application logic, but each database server requires different SQL syntax.

Select a random row with MySQL:

SELECT column FROM table
ORDER BY RAND()
LIMIT 1
Select a random row with PostgreSQL:

SELECT column FROM table
