TL;DR – By using SQL SELECT TOP, you can define the amount of data records to bring back. This command is very useful when working with significant amounts of data, but not universally supported.

In SQL Server / MS Access

Example
SELECT TOP number|percent column_name(s)
FROM name_table
WHERE condition;

In MySQL

Example
SELECT column_name(s)
FROM name_table
WHERE condition
LIMIT number;

In Oracle

Example
SELECT column_name(s)
FROM name_table
WHERE ROWNUM <= number;
