psql insert语句返回莫名其妙的错误

Question

这是我的表：

       Table "public.enrollment_tgelf"
         Column          |          Type          | Modifiers 
-------------------------+------------------------+-----------
 course_entitlement_game | character varying(250) | 
 entitlement_subject     | character varying(250) | 
 school_name             | character varying(250) | 
 grade_level             | character varying(250) | 
 username                | character varying(250) | 

这是我的插入声明：

    INSERT INTO enrollment_tgelf (course_entitlement_game, entitlement_subject, school_name, grade_level, username) 
    VALUES
    ("Lexica Vol 1","NA","tGELF","1","tgelf1");

这是我的错误：

ERROR:  column "lexica vol 1" does not exist in enrollment_tgelf

我做错了什么？

使用单引号而不是双引号来分隔字符串文字。
