If you just want to retrieve the last 10 records which were inserted (not considering update),      with your auto_increment column, you can use:
SELECT * FROM yourtablename ORDER BY your_auto_increment_column LIMIT 10;
PS: ORDER BY your_auto_increment_column is optional. This should be enough:
SELECT * FROM yourtablename LIMIT 10;
However, if the records are updatable and you want to retrieve the last 10 records which were accessed (either updated or inserted records), you need a date column like 'last_modified' which stores the date & time at which a record was inserted or updated.
Then you can use:
SELECT * FROM yourtablename ORDER BY last_modified_column LIMIT 10;

I think you need to add "DESCENDING" to those ORDER BY clauses to achieve what you want.

yes, good point. So, the query should be like:
SELECT * FROM yourtablename ORDER BY corresponding_col DESC LIMIT 10;
