How can I use named parameters in JDBC queries?

JDBC Named Parameters

Unlike ADO.NET, JDBC does not natively support named parameters in SQL queries. This means that parameters must be referenced by their positional index, which can be cumbersome and error-prone.

However, if you're not strictly confined to using plain JDBC, consider utilizing Spring's JDBCTemplate. This powerful library provides support for named parameters, allowing you to write queries like the following:

NamedParameterJdbcTemplate jdbcTemplate = new NamedParameterJdbcTemplate(dataSource);

// Create a parameter map
MapSqlParameterSource paramSource = new MapSqlParameterSource();
paramSource.addValue("name", name);
paramSource.addValue("city", city);

// Execute the query
jdbcTemplate.queryForRowSet("SELECT * FROM customers WHERE name = :name AND city = :city", paramSource);

In this example, the :name and :city parameters are bound to the name and city values from the paramSource map, making it easy to construct and execute parameterized queries.
