Executing SQL using a connection

Hi

I have a java.sql.Connection that I obtained from JDO (kodo) and want to use it to do plain jdbc stuff. Can I get spring (-dao) to make life easier? I don't want to mess around with Statements, closing them at the right time...etc.

I see that JDBCTemplate needs a DataSource. Is it possible to somehow use it if all I have is the Connection?

Thanks in advance

You can wrap your connection into a org.springframework.jdbc.datasource.SingleConnecti onDataSource and use it to instanciate the JdbcTemplate:

Code:

---

  SingleConnectionDataSource ds = new SingleConnectionDataSource(myConnection, true);
  JdbcTemplate jdbcTemplate = new JdbcTemplate(ds);

---

You should pay attention to the fact that SingleConnectionDataSource is not thread safe.

HTH

You could use a SingleConnectionDataSource that can accept a connection when you create it. You just have to make sure the connection is closed when you are done.

Code:

---

                DataSource dataSource = new SingleConnectionDataSource(con, true);

---

Another option is to use the Spring-JDO integration as outlined in this article

Thanks! Just what I needed. I have more questions though. If I use JDBCTemplate.execute("some sql") will it take care of reusing Statements or will it create one for each? What else do I need to worry about?

I'll be running lots of queries in loops and the transactions could get large.

Thanks in advance
