您正在測試什麼版本的BBOS?我發現,當您嘗試使用事務時,早期版本的OS 5會拋出「Sql邏輯錯誤」異常。唯一的解決方法是切換到隱式事務 - 只需跳過beginTransaction/commitTransaction調用即可。這將影響5.0.0.0和5.0.0.400之間的所有BBOS應用程序版本以及5.0.0.402,5.0.0.405和5.0.0.602。

爲了避免這樣或SQL injection attacks格式問題,你不應該直接嵌入字符串轉換爲SQL語句,但始終使用參數:

Statement statmnt2 = db2.createStatement(
    "INSERT INTO tbstory(Week,Year,subject,storypath) VALUES(?,?,?,?)"); 
statmnt2.prepare(); 
statmnt2.bind(1, fstNm.item(0).getNodeValue().toString()); 
statmnt2.bind(2, fstNm1.item(0).getNodeValue().toString()); 
statmnt2.bind(3, fstNm2.item(0).getNodeValue().toString()); 
statmnt2.bind(4, fstNm22.item(0).getNodeValue().toString()); 
statmnt2.execute(); 
statmnt2.close();
