I have worked with Hibernate but I think that is different approach altogether.
I haven't looked at Spring JDBC but I can see that they are similar in many ways (by looking at the documentation): This (from http://static.springframework.org/spring/docs/2.0.x/reference/jdbc.html): int rowCount = this.jdbcTemplate.queryForInt("select count(0) from t_accrual"); String surname = (String) this.jdbcTemplate.queryForObject("select surname from t_actor where id = ?", new Object[]{new Long(1212)}, String.class); Would be identical to: int rowCount = queryScalar(Integer.class, "select count(0) from t_accrual"); String surname = queryScalar(String.class, "select surname from t_actor where id = ?", 1212); And it is really the same except I use some Java 5 features (static imports, generics, varags, boxing) and have the reference to "this.jdbcTemplate" hidden away in a ThreadLocal object. However this: Actor actor = (Actor) this.jdbcTemplate.queryForObject( "select first_name, surname from t_actor where id = ?", new Object[]{new Long(1212)}, new RowMapper() { public Object mapRow(ResultSet rs, int rowNum) throws SQLException { Actor actor = new Actor(); actor.setFirstName(rs.getString("first_name")); actor.setSurname(rs.getString("surname")); return actor; } }); Would be written as: Actor actor = queryScalar(Actor.class, "select first_name, surname from t_actor where id = ?", 1212); And would require that Actor had a public constructor matching the types of first_name and surname (String, String). And I think that is taking a different route ... maybe (?) On Feb 22, 6:42 pm, Rakesh <rakesh.mailgro...@gmail.com> wrote: > have you looked at Spring JDBC?
