Question

Hi i have a query where i select values from the database and i would like to do a comparison with the selected data. I am able to create the query and pass in the parameters but i am still having some problems accessing the values returned from the query. Can someone tell me if i am on the right track, i think i wrote the last two statements incorrectly.

    String sql = "SELECT userName, password FROM tblusers WHERE userName = ? AND password = ? ";



    Object[] parameters = new Object[] {login.getUserName(), login.getPassword()};

    String dbUserName = (String)getJdbcTemplate().queryForObject(
            sql, parameters, String.class);

    String dbPassword = (String)getJdbcTemplate().queryForObject(
            sql, parameters, String.class);

If your query returns only one record, I suggest you to use:

queryForMap(String sql, Object... args)

Take a look at javadoc.

For your specific problem this should work:

Map<String,Object> results = 
        getJdbcTemplate().queryForMap(
            "SELECT userName, password FROM tblusers WHERE userName = ? AND password = ?"
            , login.getUserName()
            , login.getPassword());

String dbUserName = (String)results.get("userName");
String dbPassword = (String)results.get("password");
