java - 具有多列的 JDBC 删除语句

Question

它说当我将它输入到 sql plus 时，我只添加了 ; 就错误地结束了这个语句 它完美地工作。我究竟做错了什么？

    Statement statement = connection.createStatement();
    statement.executeUpdate("delete from aplbuk  MODEL = '"+   textField_4.getText()  + "'AND  year = '" + textField_1.getText()  + "' AND Litres = '" + textField_2.getText() 
    + "' AND ENGINE_TYPE = '" + textField_3.getText() + "'");
    statement.close();

Answer 1

查询where中的表名后缺少aplbuk关键字delete from aplbuk MODEL。

将查询更新为：

  statement.executeUpdate("delete from aplbuk  where  MODEL = '"+   
                           textField_4.getText()  + "'AND  year = '" + 
                           textField_1.getText()  + "' AND Litres = '" + 
                           textField_2.getText() + "' AND ENGINE_TYPE = '" + 
                           textField_3.getText() + "'");

此外，如果year和Litres是数字字段，则不要将值括在单引号中。
