Care to be more specific?
Your query will return only rows where region is equal to 'India' or 'Iran'. If you want rows that contain certain strings of characters, you will need to use the LIKE operator with wildcards.

First, select the region(s) where name is India or Iran. Then join back to the table to get the other names with the same region(s). If you provide DDL in the form of a CREATE TABLE statement and sample data in the form of INSERT statements, we'd be able to help you with a tested solution.

If you are pulling the records from the same table, i do not see the reason why you are going for the sub query. You can pull the records without using the sub query.

Hi,
What i understood is that you need to retrieve the data from bbc tbl where regions are India and Iran.
If i am right, then try this one:-
SELECT *
FROM BBC
WHERE REGIONS IN ('INDIA','IRAN')

Thanks all 🙂

I think you have typed the wrong column in the where clause 🙂
I assume this is the sample data from your table, and you want to filter the records which contains india and iran.
name region area population gdp
india asia 50 123 2
iran asia 20 111 3
Your query will not return data because the region column doesn't contains India / Iran..
Your query should be
select name , region from bbc where [name] in ('India','Iran')

yes, Ratheesh is correct...
may be you select wrong column...
just use select name,region from bbc where name in ('india', 'iran')
this is more enough to select the particular records of this region..
if you are really in need of some filters, then explain briefly to help us to help you...
Thanks,

No, because this doesn't return the other countries in the same region(s), which is the requirement.

>>want to select
List the name and region of countries in the regions containing 'India', 'Iran'.<<
as per ur requirement you can try this one
create table #bbc(name nvarchar(20), region nvarchar(20), area nvarchar(20), population bigint, gdp bigint)
insert into #bbc values ('india','aisa','20000',1200000,8)
insert into #bbc values ('china','aisa','20000',1200000,8)
insert into #bbc values ('iran','aisa','20000',1200000,8)
insert into #bbc values ('pakistan','aisa','20000',1200000,8)
insert into #bbc values ('london','europe','20000',1200000,8)
insert into #bbc values ('brazil','america','20000',1200000,8)
select name, region from #bbc where region in (select region from #bbc where name in('india','iran'))
we can achieve it through self join also.

i need to select name and region of the countries in the regions containing 'India', 'Iran'.
Using the sample data posted by ghanshyam.kundu, we see that the region containing India and Iran is Asia. We then see that the countries in that region are Pakistan, China, India and Iran. That's why.
