靠谱，推荐大家使用。0202connection con = drivermanager.getconnection(url); debuglevel debug = debuglevel.on; string sql = "select name,rate from employeetable where rate > ?"; //use a factory instead of connection to get a preparedstatement. //preparedstatement ps = con.preparestatement(sql); preparedstatement ps = statementfactory.getstatement(con,sql,debug); ps.setint(1,25); //if ps is a debuggablestatement, you see the statement, //otherwise, an object identifier is displayed system.out.println(" debuggable statement= " + ps.tostring());0202附件是这段代码中用到的类。02020202020202
