190、每个月份的发生额都比101科目多的科目

请用SQL语句实现：从TestDB数据表中查询出所有月份的发生额都比101科目相应月份的发生额高的科目。请注意：TestDB中有很多科目，都有1－12月份的发生额。
AccID：科目代码，Occmonth：发生额月份，DebitOccur：发生额。
数据库名：JcyAudit，数据集：Select * from TestDB

准备数据的sql代码：

drop table if exists TestDB;

create table TestDB(id int primary key auto_increment,AccID varchar(20), Occmonth date, DebitOccur bigint);

insert into TestDB values

(null,'101','1988-1-1',100),

(null,'101','1988-2-1',110),

(null,'101','1988-3-1',120),

(null,'101','1988-4-1',100),

(null,'101','1988-5-1',100),

(null,'101','1988-6-1',100),

(null,'101','1988-7-1',100),

(null,'101','1988-8-1',100);

--复制上面的数据，故意把第一个月份的发生额数字改小一点

insert into TestDB values

(null,'102','1988-1-1',90),

(null,'102','1988-2-1',110),

(null,'102','1988-3-1',120),

(null,'102','1988-4-1',100),

(null,'102','1988-5-1',100),

(null,'102','1988-6-1',100),

(null,'102','1988-7-1',100),

(null,'102','1988-8-1',100);

--复制最上面的数据，故意把所有发生额数字改大一点

insert into TestDB values

(null,'103','1988-1-1',150),

(null,'103','1988-2-1',160),

(null,'103','1988-3-1',180),

(null,'103','1988-4-1',120),

(null,'103','1988-5-1',120),

(null,'103','1988-6-1',120),

(null,'103','1988-7-1',120),

(null,'103','1988-8-1',120);

--复制最上面的数据，故意把所有发生额数字改大一点

insert into TestDB values

(null,'104','1988-1-1',130),

(null,'104','1988-2-1',130),

(null,'104','1988-3-1',140),

(null,'104','1988-4-1',150),

(null,'104','1988-5-1',160),

(null,'104','1988-6-1',170),

(null,'104','1988-7-1',180),

(null,'104','1988-8-1',140);

--复制最上面的数据，故意把第二个月份的发生额数字改小一点

insert into TestDB values

(null,'105','1988-1-1',100),

(null,'105','1988-2-1',80),

(null,'105','1988-3-1',120),

(null,'105','1988-4-1',100),

(null,'105','1988-5-1',100),

(null,'105','1988-6-1',100),

(null,'105','1988-7-1',100),

(null,'105','1988-8-1',100);

答案：
select distinct AccID from TestDB

where AccID not in

(select TestDB.AccIDfrom TestDB,

(select * from TestDB where AccID='101') as db101

where TestDB.Occmonth=db101.Occmonth and TestDB.DebitOccur<=db101.DebitOccur

);
