Hi All:
I have an issue which costs me bunch of time to develop. Basically I am trying to use discounted time in a select query but feel like get nowhere to start.
the scenarios is like this:
I have many rows of data of this and I would like to have a solution I can select time period from just like what I can do for integer and text:
Select *
From Table
Where Group = B
and Open_Date in (select the all group A's time interval)
----------------------------------
to explain this problem in plain text, I would like to select all records from Group B whose Open_Date is within the interval between Group A's Open_Date and Close_Date. Thanks all in advance.
