spring jdbctemplate delete syntax -

please can point out mistake in following code of spring jdbc template. when click delete, record not getting deleted , there no errors showing.

public void delete(string id) {     logger.debug("deleting existing person");      // prepare our sql statement using unnamed parameters style     string query = "delete person id = ?";      // assign values parameters     object[] person = new object[] {id};      // delete     jdbctemplate.update(query, person); } 

here example. pay attention:

integer id

public boolean delete(integer id){     string sql = "delete organization id = ?";     object[] args = new object[] {id};      return jdbctemplate.update(sql, args) == 1; }
