How to Use Named Parameters with JDBC?

JDBC Named Parameters

JDBC, unlike ADO.NET, does not inherently support named parameters. As a result, it can be challenging to use named parameters in JDBC like "@name" and "@city" in the example provided.

Solution Using Spring's JdbcTemplate

To overcome this limitation, consider using Spring's powerful JDBCTemplate. This utility class enables you to utilize named parameters without the need for the entire IoC container.

Using JDBCTemplate, you can employ named parameters as follows:

NamedParameterJdbcTemplate jdbcTemplate = new NamedParameterJdbcTemplate(dataSource);

MapSqlParameterSource paramSource = new MapSqlParameterSource();
paramSource.addValue("name", name);
paramSource.addValue("city", city);
jdbcTemplate.queryForRowSet("SELECT * FROM customers WHERE name = :name AND city = :city", paramSource);

This code assigns a name to each parameter within the "paramSource" object and then executes the query using the "jdbcTemplate" instance.

By leveraging Spring's JDBCTemplate, you can seamlessly incorporate named parameters into your JDBC code, simplifying your database interactions and enhancing code readability.
