Tasker Gmail Sqlite3 按标签获取电子邮件（收件箱）returns 无
Tasker Gmail Sqlite3 get emails by label (inbox) returns nothing
我是 运行 Tasker (Android) 中的一个 shell 脚本，用于查询我的电子邮件，但它总是 returns 没有。
sqlite3
/data/data/com.google.android.gm/databases/mailstore.MYEMAIL@gmail.com.db
"SELECT fromAddress || '@|@' || dateSentMs || '@|@' || Subject ||
'@|@' || snippet FROM messages m LEFT JOIN message_labels ml ON m._id
= ml.message_messageId JOIN labels l ON l._id = ml.labels_id WHERE l.name = ‘^i’ ORDER BY m._id DESC;"
这样的代码有效 ->
sqlite3
/data/data/com.google.android.gm/databases/mailstore.MYEMAIL@gmail.com.db
"SELECT fromAddress || '@|@' || dateSentMs || '@|@' || Subject ||
'@|@' || snippet FROM messages ORDER BY _id DESC LIMIT %GMAILcount;"
我怎样才能让它工作？

您的查询似乎没问题，所以我敢打赌，连接表 return NULL
当查询 SELECT * FROM labels WHERE name = '^i'
时，你得到了什么 _id
在我的例子中，它是 1 而当我 运行:
SELECT * FROM message_labels WHERE labels_id=1
我明白了……什么都没有 :) 所以这也是您的代码可能失败的地方
p.s.
我确实建议安装 SQLiteDebugger - 它在处理更复杂的查询时非常有帮助

是正确的。 m.messageId 而不仅仅是 _id
