Follow an exercise in deleting data using JDBC.
- [Instructor] So now we're to the last step…of our CRUD operation, deleting data.…So let's jump into JDBC and see how to do this operation.…So I want you to jump back into your IDE…and once again, go to source main Java,…our base package and our customer DAO.…Once again, we're going to add a private static string.…This time we will call it delete…and it will be equal to the value,…delete from customer where customer ID = ?…Now we can scroll down to our delete method…and we will implement this as we've done so many times…with a try with resources so PreparedStatement…passing in the delete,…catch the exception,…and now we can implement the method.…
And this is a relatively simple one to implement.…Statement.setLong equal to our ID…and then we will simply call statement.execute…because we don't need a return type on this.…And all there is to our delete method.…So let's go back to our JDBC executor…and we're going to get rid of most of this stuff…and we're going to go actually implement a full routine.…
But before we do that,…
