在MySQL工作台中正确运行的sql syntaxt将Java中的语法错误返回为prepared语句

我使用以下方法在java中运行准备好的sql语句，但它会给我一条语法错误消息：

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException：您的SQL语法有错误；检查与您的MySQL服务器版本对应的手册，以了解在“更新临时测试”附近使用的正确语法 内部合并条例草案 在第6行的临时测试中，跟踪号=ups\U账单.tra

有人能指出可能的错误吗？非常感谢

下面是该方法的代码：

private void updateTemp(){

try{

String sql="insert into temp_test (tracking_number, account_number, service, to_name, to_address, to_city, to_state, to_zip, to_zone, invoice_number, invoice_date, ship_date, account_code,entry_type_1,entry_type_2) \n" +

不能发出以“；”分隔的两条单独的sql语句在对executeUpdate的相同调用中

在这种情况下，先插入，然后更新。

接口（及其子接口

PreparedStatement

）允许对每条语句执行单个查询。您的查询包含多个语句，因此无法执行。您必须准备单独的语句并执行它们

如果您想要一个全有或全无的行为，您可以使用连接启动一个事务，在执行所有这些操作时执行commit，并在出现异常时回滚

下面是代码的大致情况：

try {
    //you state that the transaction needs a commit statement
    conn.setAutoCommit(false);
    //perform your DML statements
    //...
    //explicitly state you're committing the transaction
    conn.commit();
} catch (Exception e) {
    //rollback the transaction
    conn.rollback();
    //handle the exception...
    //Note: always retrieve the stacktrace
    //it would be better to use a log or another way to archive it
    //this is a pretty basic example
    e.printStacktrace(),
}
