spring jdbctemplate delete syntax

spring jdbctemplate delete syntax

Please can someone point out any mistake in my following code of spring
jdbc template. When I click delete, the record is not getting deleted and
there are no errors showing.
public void delete(String id) {
logger.debug("Deleting existing person");
// Prepare our SQL statement using Unnamed Parameters style
String query = "delete from person where id = ?";
// Assign values to parameters
Object[] person = new Object[] {id};
// Delete
jdbcTemplate.update(query, person);
}
