兔子--Parameter index out of range (3 > number of parameters, which is 2).

 
		String sql2 = "insert into supplygoods(id,supplyaccount,goodsaccount,state)values(19,?,?,?)";

		try {
			 
			PreparedStatement stm2 = conn.prepareStatement(sql2);
			// 结果集
			 
			stm2.setInt(1, g.getSupplyAccount());
			stm2.setInt(2, g.getAccount());
			stm2.setInt(3, 0);

			 
			stm2.execute();

原因：sql2中有三个？，设置数据的时候，也需要为sql2设置三个数据，

如果：你只为sql2设置了2个数据，则会出现如上问题。
