mysql - MySQL workbench和mysql-connector-java-5.1.15之间的区别

我试图通过使用mysql-connector-java-5.1.15的ant任务在mysql服务器上运行以下sql脚本，但它不起作用，我在第三个命令上收到以下错误。我可以从ant获得其他脚本正常工作，因此它不是连接问题。

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，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，我需要做些什么来解决它？

非常感谢任何帮助罗布。
