为什么sqlfiddle说这个sql不工作？

Question

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

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

我已将问题缩小到了一线：

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);

请帮帮我。每次它只是在android控制台中说出来，无论检查多少错误并阻止我输入的代码，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);
