in code i'm using prepared statement insert 7 parameters :

connection.preparestatement(inserttablesql); preparedstatement.setstring(1,"31/07/12"); preparedstatement.setint(2, 1); preparedstatement.setint(3, 2); preparedstatement.setint(4, 3); preparedstatement.setint(5, 4); preparedstatement.setint(6, 4); preparedstatement.setfloat(7, 6); preparedstatement.executeupdate();
