插入,选择和where语句组合

Question

如何根据表C中的条件将表A中的记录插入表B.

表A:

ID  Name   DateFrom   DateTo
1   Alex   22-7-2015  26-7-2015
2   Alice  21-8-2015  25-8-2015

表C:

ID  Quarter   DateFrom   DateTo
1   Quater 1  1-7-2015  31-7-2015
2   Quater 2  1-8-2015  31-8-2015

如果表A中的记录在表C中的日期范围之间,它将插入到新的表B中.

赎回是表B.

insert into redemption(staffID,staffName,department,pointsAccumulated,referrerID) 
select referrerStaffID,referrerName,referrerDepartment,SUM(points),activeDirectoryID 
FROM referral 
WHERE NOT EXISTS (select * from redemption1 where referrerID=activeDirectoryID) group by activeDirectoryID;

Answer 1

尝试这个

Insert into tableB(Id,name,datefrom,dateto)
select t1.Id,t1.name,t1.datefrom,t1.dateto from tableA as t1 
inner join tableC as t2 on t1.id=t2.id 
where 
t1.datefrom between t2.datefrom and t2.dateto or 
t1.dateto between t2.datefrom and t2.dateto
