Hi. Imagine the foolowing situation: i got one connection, and i have several preparedStatements to execute, each with different parameters. Is is good practice to close the connection in a finally() statement. But what about statements and resultset ? Is there an advantage to close them explicitely : -in the finally statement, before the connection.close() (see code A) ? -in the try statement, between each statement execution for the resultset, and between each redefinition for each preparedStatement (see code B) ? code A: Connection con=null; PreparedStatement stmt=null; Resulset rs=null; try { stmt=... stmt.set... rs=stmt.execute(); stmt.set... rs=stmt.execute(); stmt=... stmt.set... rs=stmt.execute(); stmt.set... rs=stmt.execute(); } finally { rs.close(); stmt.close(); con.close() } code B: Connection con=null; try { PreparedStatement stmt=... stmt.set... Resulset rs=stmt.execute(); rs.close(); stmt.set... rs=stmt.execute(); rs.close(); stmt.close(); stmt=... stmt.set... rs=stmt.execute(); rs.close(); stmt.set... rs=stmt.execute(); rs.close(); stmt;close(); } finally { con.close() } -- Guillaume Rousse Iremia - Universit� de la R�union Sleep doesn't exists.
