Android Sqlite建表语句出错

 ublic static final String CREATE_TABLE = "create table HistoryNote ("+
            "id integer primary key autoincrement,"+
            "date text,"+
            "from text,"+
            "content text,"+
            "tag integer,"+//tag = 0是历史记录，tag = 1是记事簿
            "isCollected integer)";// isCollected = 0是未被收藏，=1是收藏

但是错误提示在from附近有错！

`android.database.sqlite.SQLiteException: near "from": syntax error (code 1): , while compiling: create table History (id integer primary key autoincrement,date text,from text,content text,tag integer,isCollected integer)

我是个安卓开发初学者，这个问题在哪？
