Still looks identical. I cannot figure out what you want.

Please post your data as:

  1. CREATE TABLE
  2. INSERT INTO

As it is, I cannot tell where each column starts and stops

Hi

Create table test(no,int,description varchar(200))
insert into test(10,'[start 1/dec/2015.....end 6/dec/2015] [start 4/dec/2015 ...end 10/dec/2015] [start 4/dec/2015 ... end 10/dec/2015]')

insert into test(20,'[start 1/nov/2015.....end 6/nov/2015] [start 4/nov/2015 ..end .10/nov/2015] [start 14/nov/2015 ...end 20/nov/2015]')

thanks britton..

please find the below ...

insert into test(30,'[start 1/oct/2015.....end 6/oct/2015] [start 4/oct/2015 .. end 10/oct/2015. ]')

decription column can have multiple weeks (1 or many weeks) status .

based on the 'start' and 'end ' tags i need to fetch only last 2 weeks status only

example id 10 and 20 has 3weeks update status(based on start and end)

i need 2 weekks status from the description column

Thanks for the data.

Unfortunately there is no easy query to get you what you want. Basically, the table is defined poorly. You need something more like:

CREATE TABLE test (no int, StartDate date EndDate date)
INSERT INTO test (no, StartDate, EndDate) values
(10, '20151201', 20151206'),
(10, '20151204, '20151210'),
...

Then it's easy,

I agree. In general, for a RDBMS, if you have to parse data from a column to derive meaning for the data, the design of the table is flawed. It causes huge problems for that reason alone and it makes performance a disaster. If you have any control over the design of the tables and how the data is stored, fix this as soon as possible.
