为避免格式化此类问题或SQL injection attacks，您不应将字符串直接嵌入到SQL语句中，而应始终使用参数：
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();

您正在测试哪种版本的BBOS？我发现当您尝试使用事务时，OS 5的早期版本会抛出“Sql logic error”异常。唯一的解决方法是切换到隐式事务 - 只需跳过对beginTransaction / commitTransaction的调用。这会影响5.0.0.0和5.0.0.400以及5.0.0.402,5.0.0.405,5.0.0.602之间的所有BBOS应用程序版本。
