SQL to select a random row from a database table
There are lots of ways to select a random record or row from 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 ORDER BY RANDOM() LIMIT 1
Select a random row with Microsoft SQL Server:
SELECT TOP 1 column FROM table ORDER BY NEWID()
Select a random row with IBM DB2
SELECT column, RAND() as IDX FROM table ORDER BY IDX FETCH FIRST 1 ROWS ONLY
Thanks Tim
Select a random record with Oracle:
SELECT column FROM ( SELECT column FROM table ORDER BY dbms_random.value ) WHERE rownum = 1
