android - 得到错误 : Caused by: android. database.sqlite.SQLiteException: near "of"

Question

我收到这个错误:"由:android.database.sqlite.SQLiteException: near "of": syntax error: CREATE TABLE List of Notes (_idINTEGER PRIMARY KEY AUTOINCREMENT, notes_nameTEXT NOT NULL notes_contentTEXT NOT NULL notes_timeTEXT NOT NULL); "

我正在使用这段代码:

 db.execSQL("CREATE TABLE " + DATABASE_TABLE + " (" + 
                        KEY_ROWID + "INTEGER PRIMARY KEY AUTOINCREMENT, " +
                        KEY_NAME + "TEXT NOT NULL " + 
                        KEY_CONTENT + "TEXT NOT NULL " +
                        KEY_TIME + "TEXT NOT NULL);"

                        );

这是我的日志:

除了其他答案中的重要建议。

CREATE TABLE List of Notes (

表名必须是一个单词。考虑 ListOfNames、List_of_Names 等
