前端传入id varchar类型的id值，考虑到17级学生学号为11位，后续年级的学生的学号可能会突破int值的限制，所以使用varchar类型
1、t_certificate 证书表，由id查四六级成绩，查询条件为
（1）成绩>425的四六级证书
select ce_student_id as 学号,ce_student_name as 学生姓名,
ce_name as 考试科目,ce_score as 考试成绩
from t_certificate
where ce_student_id = "1220106204" and
ce_name like "外语大学英语_级CET_" and ce_score>=425 ;
（2）成绩为合格的证书
select ce_student_id as 学号,ce_student_name as 学生姓名,
ce_name as 考试科目,ce_score as 考试成绩
from t_certificate
where ce_student_id = "13200212108" and
ce_score = "合格" ;
（3）成绩为及格的证书
select ce_student_id as 学号,ce_student_name as 学生姓名,
ce_name as 考试科目,ce_score as 考试成绩
from t_certificate
where ce_student_id = "14200119104" and
ce_score = "及格" ;
2、t_competition 竞赛表
考虑到部分数据没有id,应该先从学生基本表中查名字，再由名字查竞赛名称
竞赛名称=co_name+co_level+co_awards 以第一条为例，则是大学生集成电路设计大赛国家级三等奖
select st_name as 学生姓名,
concat_ws('',co_name,co_level,co_awards) as 奖项
from t_competition,t_student
where co_student_name like
'%'|| (select st_name
from t_student
where st_id = "14200107126")||'%' ;
3、t_excellent_student 按照id查
单项名称为ex_year+ex_honor
select ex_student_name as 姓名,
ex_student_id as 学号,
concat_ws('',ex_year,'年',ex_honor) as 荣誉
from t_excellent_student
where ex_student_id = "14200141111" ;
4、t_innovation_train 创新训练表，俗称科研立项表
按照名字来查，使用模糊查询
单项为in_year+in_category+in_name
select t_student.st_name,
concat_ws('',in_year,'年',in_category,':',in_name) as 科研项目
from t_innovation_train,t_student
where in_students like
'%'|| (select st_name
from t_student
where st_id = "14200135118")||'%' ;
5、t_party_member 党员表
按名字来查
单项为pa_state+“党员”
select pa_student_name as 学生姓名,
concat_ws('',pa_state,'党员') as 党员状态
from t_party_member
where pa_student_name="杨磊";
6、t_post_graduate 考研表
按照名字来查
单项为 po_new_school+“研究生”
select po_student_name as 学生姓名,
concat_ws('',po_new_school,'研究生') as 研究生状况
from t_post_graduate
where po_student_name="何勇";
7、t_push_excellent 推优表
按照名字来查，若查询到数据
单项为2018.6.14+“已被推优”
select pu_student_name as 学生姓名,
concat_ws('',pu_time,'已被推优') as 推优状况
from t_push_excellent
where pu_student_name="王辉";
8、t_scholarship 奖学金表
按照学号来查。可能一个同学不止一条数据
单项为sc_year+“年获得”+sc_award
如果sc_award为三个字则sc_award=sc_award+”学金”
否则 sc_award=sc_award
备注:返回字符串类型的数组
select sc_student_name as 学生姓名,
concat_ws('',sc_year,'年获得',sc_awards,'学金') as 荣誉
from t_scholarship
where sc_awards like "___"
and sc_student_id = "16200143130"
union
select sc_student_name as 学生姓名,
concat_ws('',sc_year,'年获得',sc_awards) as 荣誉
from t_scholarship
where sc_awards like "____%" and
sc_student_id = "16200143130";
