＆＃34;与＆＃34;子句查询在android中不起作用

Question

这是我的rawQuery

WITH authorRating(aname, rating) AS SELECT aname, AVG(quantity) FROM book GROUP BY aname

错误在Logcate中

   android.database.sqlite.SQLiteException: near "WITH": syntax error (code 1):

Answer 1

自SQLite 3.8.3起支持

WITH，而不是shipped with all Android versions。

无论如何，此查询不是valid WITH clause，并且缺少实际查询。
