Invalid Cursor Position Causes Java.sql.SQLException

The commonly used phrase is that starting from Java 7, try-with-resources can be utilized to automatically close resources. As an alternative solution, it is recommended to avoid setting parameters in a way that may cause syntax errors or SQL injection. Instead, PreparedStatement can be used. It is important to remember to close both the statement and connection after finishing. However, this approach only allows for setting a maximum of two tickets, not an unlimited number.

The approach is merely a stopgap measure since it merely handles the exception. Unfortunately, it restricts me to specifying only two tickets instead of any number.

 public void buyTicket(int id,int n,int price) throws SQLException < crs.setCommand("SELECT PAYID FROM PAYMENTINFO WHERE ACCOUNT = '"+account+"'"); crs.execute(); crs.next(); payID = crs.getInt("PAYID"); try< for(int i=0;i> catch(sqlexception e)< system.out.println(" message: " + e.getmessage()); e="e.getNextException();>" try < crs.setcommand("update events set maxtickets="MAXTICKETS" - "+n+"where eventid="+id); crs.execute(); crs.next(); >catch(SQLException e ) < System.out.println(" message: " + e.getmessage()); e="e.getNextException();" >>

It is recommended to utilize PreparedStatement consistently as it assists in minimizing the vulnerability to SQL injection attacks.

try < Connection conn = getConnection(); try < String sql = "SELECT * FROM cartsusc WHERE vendedor = ?"; PreparedStatement ps = conn.prepareStatement(sql); try < ps.setString(1, this.cmbx_vend.getSelectedItem()); ResultSet rs = ps.executeQuery(); try < if (rs.next()) < this.txt_dato.setText(rs1.getString("vendedor")); >> finally < rs.close(); >> finally < ps.close(); >> finally < conn.close(); >> catch (SQLException e) < //handle >

Beginning with Java 7, the utilization of try-with-resources is possible to automatically close the resources.

String sql = "SELECT * FROM cartsusc WHERE vendedor = ?"; try ( Connection conn = getConnection(); PreparedStatement ps = conn.prepareStatement(sql); ) < ps.setString(1, this.cmbx_vend.getSelectedItem()); try (ResultSet rs = ps.executeQuery()) < if (rs.next()) < this.txt_dato.setText(rs1.getString("vendedor")); >> > catch (SQLException e) < //handle >

Avoid setting parameters in a way that may result in a syntax error or SQL injection. Instead, opt for using a PreparedStatement.

String query = "SELECT * FROM cartsusc WHERE vendedor = ?"; try (PreparedStatement pstm = connection.prepareStatement(query)) < pstm.setString(1, this.cmbx_vend.getSelectedItem()); ResultSet rs1 = pstm.executeQuery(); if(rs1.next())< this.txt_dato.setText(rs1.getString("vendedor")); //this.txt_dato.setText(rs1.getString(1));//or you can get your result like this >> 

Remember to properly end your statement and disconnect once you are done.
