The JdbcTemplate class is the central class in the JDBC core package.

It simplifies the use of JDBC and helps to avoid common errors.

It executes core JDBC workflow, leaving application code to provide SQL and extract results.

This class executes SQL queries or updates, initiating iteration over ResultSets and catching JDBC exceptions.

To update records in a database using the JdbcTemplate class one should perform the following steps: Use the DataSource class, a utility class that provides connection to the database.

Set the credentials needed to the datasource, using the inherited methods setPassword(String password), setUrl(String url) and setUsername(String username) API methods of AbstractDriverBasedDataSource class, as also the setDriverClassName(String driverClassName) API method of DriverManagerDataSource.

Create a new Datasource object having the above configuration.

Create a new JdbcTemplate object, with the given datasource to obtain connections from.

Use the update(String sql, Object args, int argTypes) API method of JdbcTemplate, to issue the SQL update operation via a prepared statement, binding the given arguments.

The given parameters are the String containing the sql query, the arguments to bind the query, and the types of the arguments, as described in the code snippet below.
