Can I do an insert and update in same query?
BEFORE:
MemberID |   SubsID |   StartDate  |  EndDate
------------------------------------------------
1001     |   10     |   2012-12-21 |  2012-12-31 
2002     |   10     |   2012-12-22 |   
AFTER:
MemberID |   SubsID |   StartDate  |  EndDate
------------------------------------------------
1001     |   10     |   2012-12-21 |  2012-12-31 
2002     |   10     |   2012-12-22 |  2012-04-13 
2002     |   10     |   2012-04-13 |   
Get the rows:
select * from MemberSubs 
where SubsID = 10 and EndDate is null;
Insert new rows:
insert into 
  MemberSubs(MemberID, SubsID, Price, StartDate)
select 
  MemberID, SubsID, Price, Current Date 
from 
  MemberSubs 
where 
  SubsID = 10
  and
  EndDate is null
Update the old rows:
update MemberSubs 
set 
  EndDate = current date
where 
  SubsID = 10
  and
  EndDate is null
  and
  StartDate < Current Date
Is it possible to achieve this in one query (without using stored procedures or trigger etc)
Thank you.
