我是ORMLite for android的初学者。我需要按照＆＃34; name＆＃34;的字母顺序从我的Accounts表中选择某些行。列值并显示名称为＆＃34的行;其他＆＃34;应该在列表的最后。我用queryBuilder().orderByRaw(...)来获取它，但结果是SQLException.Below是该异常的完整堆栈跟踪。

以下是我使用的代码
listCoaAct=new ArrayList<COAAccount>();
List<Integer> idList = new ArrayList<Integer>();
idList.add(5);
idList.add(43);
List<Accounts> getCoa = dbHelper.getAccountsDao().queryBuilder()
.orderByRaw("CASE WHEN name=Others THEN 1 ELSE 0 END,name")
.where().eq("parent_id",parentId).and().eq("active", true)
.and().notIn("id", idList).query();
如何解决我的问题？
答案 0 :(得分：2)
原因就在于您的错误消息：
没有这样的专栏：其他
您必须在引号中设置“其他”，否则您的SQL引擎将尝试查找具有该名称的列。
答案 1 :(得分：1)
name=Others是这里的问题。
在这里，Others是一个字符串文字，所以它应该用单引号（＆＃39;）括起来，如：
CASE WHEN name='Others' THEN 1 ELSE 0 END,name
