MySQL工作臺和mysql-connector-java-5.1.15之間的區別

我想通過使用mysql-connector-java-5.1.15的ant任務在mysql服務器上運行以下sql腳本，但它不起作用並且在第三個命令中出現以下錯誤。我可以讓其他腳本在螞蟻中正常工作，因此它不是連接問題。MySQL工作臺和mysql-connector-java-5.1.15之間的區別

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，腳本在連接到相同服務器的MySql工作臺（v5.2.31）中工作得非常好。爲什麼要這樣呢？數據庫是latin1，字符集系統是uft8。這可能是問題的一部分嗎？如果是的話，我需要做些什麼來解決它？

非常感謝任何幫助 Rob。

不知道jdbc，但通常您只能通過c-lib在一段時間內共享一條sql語句。（我猜也是由jdbc使用的）。如果你使用ant，你不能直接調用mysql客戶端。例如'mysql -uusername -ppassword Rufinus 2011-06-08 15:43:25

只是猜測，但你可能只能發送一個命令每個查詢。所以把它們分開;並單獨查詢。我用另一種語言解決了這個問題。

似乎可以發送多個命令，但jdbc引擎在提交之前會執行一些查詢解析。在這種情況下，它不喜歡\ * * \評論風格，並且它曾經用＃語法替換過 – 2011-06-28 15:56:12
