MySQL 工作台和 mysql-connector-java-5.1.15 的区别

Question

我正在尝试使用 mysql-connector-java-5.1.15 通过 ant 任务在 mysql 服务器上运行以下 sql 脚本，但它不会在第三个错误上工作我可以从 ant 让其他脚本正常工作，所以这不是连接问题。

You have an error in your SQL syntax; check the manual that corresponds to 
your MySQL server version for the right syntax to use near 'DROP TABLE IF 
EXISTS `tmp_cui_desc`;
CREATE TABLE `tmp_cui_desc` (
    CUI CHAR(8' at line 15

奇怪的是，该脚本在连接到同一服务器的 MySql 工作台（v5.2.31）中工作得非常好。 为什么会这样？ 数据库是 latin1，字符集系统是 uft8。 这可能是问题的一部分吗？ 如果是这样，我需要做什么来修复它？

非常感谢罗布的任何帮助。

只是一个猜测，但您可能每个查询只能发送一个命令。 所以将它们分开; 并单独查询。 我用不同的语言遇到了这个问题。
