MySQL的INSERT失敗

Question

我的代碼是

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"; 

我嘗試插入來自德比即IM數據複製數據到MySQL，但是當我在下面即時得到錯誤的命令輸入如下所示，推derby2mysql是文件，其中包含代碼

C:\symmetric-ds-3.0.1-server\symmetric-ds-3.0.1\samples>sh ij.sh push-derby2my 
    l.sql 
    ij version 10.5

Answer 1

如果你讀了錯誤..

類 'org.jumpmind.symmetric.db.derby.DerbyFunctions' 確實ñ前ist或無法訪問。

這是防止任何插入發生，所以你後選擇沒有得到任何東西。

由於錯誤提示，請檢查：

1. 如果參考org.jumpmind.symmetric.db.derby.DerbyFunctions是現有
2. 如果文件org.jumpmind.symmetric.db.derby .DerbyFunctions存在（可能是這裏的問題）
3. 如果類是公共的（也許是）
