Muni writes "I have situation as follows. We have three tables.
1. Person - Id, Name and address
2. Skills - ID, Name
3. PersonSkills - personID, SkillID. One prson may have many skills. Each skill may be provided by many persons. Each person may have different set of skills.

Now the question is, I want a query, where by I would like to get the list of people who posseses a given list of skills (list may have varied numbers). The person should have all the skills as mentioned in the list.

Thanks
Muni"

This might work:

Select z.*
From Person as Z
Inner Join
(
Select PersonId
From PersonSkills as A
Inner Join (Select id From skills Where ','+id+',' like ','+@SkillListById+',') as B
On A.SkillId = B.Id
Group By PersonId
Having count(*) = (Select count(*) From skills Where ','+id+',' like ','+@SkillListById+',')
) as Y
On Z.id = y.PersonId
