#263 — Close resultset but not t

  To: comp.lang.java.databases
I have a method that has a resultset as return value, so i can not close the 
connection:

public ResultSet getSomething()
 {

  StringBuffer sql = new StringBuffer();
  Statement stmt = null;

  try {
   con = SQLTestFactory.createConnection();
   stmt = con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,
     ResultSet.CONCUR_READ_ONLY);
   sql.append("SELECT Someone from Something ");
   rs = stmt.executeQuery(sql.toString());
   return rs;

  } catch (SQLException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }

  return rs;
 }
}


After i collect the rs i close it, but how do i close the connection?

The code isn't so good, that you obtain a connection and don't
retain/manage it. That being said, you can do this in the code
that is closing the result set, instead of closing the result set:

rs.getStatement().getConnection().close();

By spec, closing the connection will close the statement which
will close the result set.
