SQL Top and Limit

TOP and LIMIT statements determine the amount of records in the result. For example, you want to limit the result with 7 records. In MS SQL and PostgreSQL, use the LIMIT keyword at the end of the query:


              1234
            
--Find top-3 the eldest songs
SELECT title, year FROM songs
ORDER BY year
LIMIT 3

In MySQL syntax, use TOP keyword with select to limit the number of output rows. You can also set a percentage: SELECT TOP 50 PERCENT.

During this course we will use the LIMIT statement.
