Question

这个代码。我已经提到了查询停止的位置。控制台也没有错误。可能是什么问题呢。我正在使用postgres数据库。从jsp servlet获取数据并通过servlet作为字符串传递给dao。但由于我的数据库格式不同，我想将变量转换为各自的类型。但我首先要检查插入查询是否适用于虚拟数据。似乎每件事情都运行良好，但代码流停在提到的位置，并且我的数据库中也没有插入数据。

 public void doInsert(Connection conn, String i, String nam,String indate, String amont, String tx, String tot,String closd, String shipvia, String not) throws Exception {
            ResultSet rs = null;
            ResultSet rs1 = null;
            Statement st=null;
            Statement st1=null;
            // TODO Auto-generated method stub
            try{
            /*  String in=indate;

                String reverse = new StringBuffer(in).reverse().toString();
                System.out.println(reverse);

                System.out.println(reverse);
                SimpleDateFormat sdf = new SimpleDateFormat("yyyy-M-dd");
                String dateInString = indate;
         Date date = sdf.parse(dateInString);
                System.out.println(date);*/


                /*String it=i; 
                String n=nam; 
                String in=indate; 
                String a=amont; 
                String t=tx;
                String tota=tot; 
                String closed=closd; 
                String ship_via=shipvia; 
                String note=not;
                to_date("+date+",'YYYY-MM-DD')*/
                System.out.println("came above sql");
                /*to_date("+date+",'YYYY-MM-DD')*/
                String sql="insert  into invheader(id,invdate,client_id,amount,tax,total,closed,ship_via,note) values(100001,to_date('1963-09-01', 'YYYY-MM-DD'),100001,100.00,20.00,120.00,TRUE,'tnt','note 1')";
                    //"insert  into invheader(id,invdate,client_id,amount,tax,total,closed,ship_via,note) values('',to_date('1963-09-01', 'YYYY-MM-DD'),"+i+","+amont+","+tx+","+tot+","+closd+","+shipvia+","+not+")";
                System.out.println("after 1st query");
                String sql1="insert  into clients(client_id,name) values("+i+","+nam+")";
                System.out.println("after 2nd query");
                st =conn.createStatement();
                st1 =conn.createStatement();
                //Statement stmt1 = conn.createStatement();//connection to statement
                System.out.println("above execute"); //<======= code stops here
                rs=st.executeQuery(sql); 
                System.out.println("above execute1");
                rs1=st1.executeQuery(sql1);
                System.out.println("inserted dao");

            }catch(Exception e){
            e.printStackTrace();
            throw e;
        }


            // TODO Auto-generated method stub

        }

请帮帮我。可能是什么原因？

Postgres插入查询不起作用？
