PostgreSQL - How to select several random records from a table.

 







How to select several random records from a table.

Sometimes it is necessary to select several random records from a database.

This task can be achieved by using built-in function RAND () using LIMIT clause and ORDER BY clause.

Suppose you have a table SoftFernNews from which you want to select 10 random rows containing Titles and IDs every time when user visits your home page.

Solution:

select NewsID, NewsTitle
from SoftFernNews
order by rand() limit 10

Alias is useful only if you're delnaig with complex queries involving multiple tables; specially if you run the risk of 2 different tables having the same or similar field names.
