Objectives are :

The table at a time can have only N number of rows.
When a row is inserted, the oldest row shpuld be deleted to maintain the row count as N.

Pls suggest approaches.

UPDATE:

Past Mysql 5 you could use a trigger to achieve this.

then your triggered sql would be along the lines off:

DELETE FROM foo WHERE id NOT IN (SELECT id FROM foo ORDER BY id DESC LIMIT 10)
