create table test (id int,countries varchar(25))

insert into test values(100,'IN, AU, GB, FR')

insert into test values(101,'GB, FR, IN')

insert into test values(102,'IN, AU')

insert into test values(103,'AU, GB')

insert into test values(104,'GB, FR, IN, AU')

If it's the above table, the query below will help:

select id from test where countries like ('%AU%') and countries like ('%IN%')

here's an even simpler query that those i've seen posted - but no doubt i have overlooked something 🙂

CREATE TABLE #Test

(ID INT, Countries CHAR(2));

INSERT INTO #Test

(ID, Countries)

SELECT '100','IN' UNION ALL

SELECT '100','AU' UNION ALL

SELECT '100','GB' UNION ALL

SELECT '100','FR' UNION ALL

SELECT '101','GB' UNION ALL

SELECT '101','FR' UNION ALL

SELECT '101','IN' UNION ALL

SELECT '102','IN' UNION ALL

SELECT '102','AU' UNION ALL

SELECT '103','AU' UNION ALL

SELECT '103','GB' UNION ALL

SELECT '104','GB' UNION ALL

SELECT '104','FR' UNION ALL

SELECT '104','IN' UNION ALL

SELECT '104','AU'

query:

SELECT ID FROM #test WHERE countries LIKE 'IN'

AND ID IN(SELECT ID FROM #test WHERE countries LIKE 'AU')

did i miss something?:)

Heh... nope... see above where I posted...

SELECT ID

FROM #Test

WHERE Countries IN ('IN','AU')

GROUP BY ID

HAVING COUNT(*) = 2

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Yes, you missed the first reply (mine) which your query is identical too (except for your superfluous use of the LIKE operator).
