android - 为什么 sqlfiddle 说这个 sql 不起作用？

Question

http://sqlfiddle.com/#!5/5cb3a/1

我使用 android sqlite，所以我使用 db.execsql(); 形式的非格式化 sql；

我已将问题缩小到以下范围：

INSERT INTO pains (painlocation VARCHAR , painlevel INT(1) , starttime VARCHAR , endtime VARCHAR , symptoms VARCHAR , triggers VARCHAR , medications VARCHAR , othertreatments VARCHAR , notes VARCHAR) VALUES (Eyes , 8 , 12:00 , 12:01 , None , Eyes, None, None , None);

请帮我。每次它只是在 android 控制台中这样说，无论我输入多少错误检查和阻止代码，我总是得到错误。：

Caused by: android.database.sqlite.SQLiteException: near "VARCHAR": syntax error (code 1): , while compiling: INSERT INTO pains (painlocation VARCHAR , painlevel INT(1) , starttime VARCHAR , endtime VARCHAR , symptoms VARCHAR , triggers VARCHAR , medications VARCHAR , othertreatments VARCHAR , notes VARCHAR) VALUES (Eyes , 8 , 12:00 , 12:01 , None , Eyes, None, None , None);
