MySQL的INSERT失败

Question

我的代码是

connect 'jdbc:derby:sampleclient'; 
    set schema SYMMETRIC; 
    insert into "sale_transaction" ("tran_id", "store", "workstation", "day", "seq") values (1000, '1', '3', '2007-11-01', 100); 
    insert into "sale_return_line_item"("tran_id", "item_id"," price", "quantity") values (1000, 110000055, 0.65, 1); 
    select * from "sale_transaction"; 
    select * from "sale_return_line_item"; 

我尝试插入来自德比即IM数据复制数据到MySQL，但是当我在下面即时得到错误的命令输入如下所示，推derby2mysql是文件，其中包含代码

C:\symmetric-ds-3.0.1-server\symmetric-ds-3.0.1\samples>sh ij.sh push-derby2my 
    l.sql

Answer 1

如果你读了错误..

类 'org.jumpmind.symmetric.db.derby.DerbyFunctions' 确实ñ前ist或无法访问。

这是防止任何插入发生，所以你后选择没有得到任何东西。

由于错误提示，请检查：

1. 如果参考org.jumpmind.symmetric.db.derby.DerbyFunctions是现有
2. 如果文件org.jumpmind.symmetric.db.derby .DerbyFunctions存在（可能是这里的问题）
3. 如果类是公共的（也许是）

看起来您没有安装SymmetricDS软件包。您可以从here下载。
