DELETE Query

JdbcTemplate update() method

In the previous lesson, we learned that the update() method of the JdbcTemplate is used to execute INSERT as well as UPDATE queries. In this lesson, we will write a query to delete a row based on the ID value using the update() method of the JdbcTemplate class.

Let’s call the method which implements the delete functionality, deletePlayerById(). This method returns an integer value of the number of rows that were affected by the query.
