Column 'id' in where clause is ambiguous

       使用mabatis多表查询，发现报错： Column 'id' in where clause is ambiguous。

Column 'id' in where clause is ambiguous。的意思是：列"id"是模棱两可的。

sql语句：select psc.* ,ssc.id as sscid,c.course_name from t_parent_select_course psc left join t_school_select_course ssc on psc.school_sel_course_id=sscid left join t_course
c on ssc.courseid=c.id where id=1

原来是2张表都有id字段，应该指定是哪一张表的id。
