Question

以下SQLite查询在Android 4.4及更低版本上运行正常，但它会导致异常：“android.database.sqlite.SQLiteException：ambiguous column name：number（code 1）：......”在android 5.0上然后。我检查了SQLite发布文档，但没有看到任何可能影响我工作的更改。我有什么遗漏的东西吗？

Answer 1

... where nm.number=coalesce(C.number,S.Number) ...
... where nm.number=coalesce(C.number,S.Number) ...
... where css.number = S.Number) ...
... coalesce(C.number,S.Number) ...
... where nm.number=coalesce(C.number,S.Number) ...
... group by newCallType,number,...
                         ^^^^^^

number的所有出现都使用表别名限定，但最后一个除外。那个确实是模棱两可的。

SQLite查询适用于android 4.4，但在android 5.0上崩溃
