to listen database table by java

I need to watch a table i.e., whenever there is insert in a table my java code will do some actions. For this I am planning to use while(true) loop. In this infinite loop I will select data from table. If there is some new insert in table, I will perform my functions and will continue to do this whenever there is a new insert in table.

My code will run forever and there will be scheduled shutdown in a week and will be restarted in 5 - 10 minutes.

Is it a right approach to use while(true) ?
Any other way to listen database table ?

Note: database is Teradata (RDBMS) and not Oracle

That is definitely not a right approach.

Check out with the hibernate.
