Get min date by compare 2 Row
Hi friends,

select min(START_DATE,END_DATE) from TABLE1
where (( START_DATE like '%APR%') or (START_DATE like '%MAY%'))
and END_DATE like '%MAY%';

START_DATE END_DATE
------------------ ----------------
29-JAN-16 01-FEB-16
26-FEB-16 29-FEB-16
01-FEB-16 29-FEB-16

In the above table i have to find the Minimum date from the 2 rows, Have to compare the 2 row.

I need the ans as 29-JAN-16,.

Have to do(modify) in the same above Query.

Any Idea?

Thanks in advance.

I am not clear about the requirement.
As per my understanding. For the above data you want only one date date, that should be minimum of Start_date or End_date for the entire data right?

Try the following query
select top 1 * from (select min(START_DATE,END_DATE) as Mdate from TABLE1 where (( START_DATE like '%APR%') or (START_DATE like '%MAY%')) and END_DATE like '%MAY%') as aa order by Mdate ;

Select min(cast (start_date) as datetime),
min(cast(end_date) as datetime)
from table1

(select min(START_DATE,END_DATE)  as Mdate from TABLE1 
where (( START_DATE like '%APR%') or (START_DATE like '%MAY%')) 
and END_DATE like '%MAY%') as aa

do not use LIKE for date, better to use BETWEEN or IN query, see below query snippet
SELECT MIN(mydate) mindate, MAX(mydate) maxdate
FROM(
SELECT expenseDate AS mydate
FROM tableA
UNION ALL
SELECT invoicedate AS mydate
FROM tableB
) AS table
Thanks
