I have a query to pull the first contact of students.
The table has all contacts like parent/guardian, friends family, emergency contact etc.
I would like to the first primary contact in this order,
1. initial contact, 2. same as student address and also have to be parents,
3. live with and also a parent, 4. parents 5. friends.
I don't know how to pull 2 and 3 . because it looks like it needs to concatenate the columns.
here is my initial query
Select Min(U2.Id) Keep (Dense_Rank First Order By U2.Initial_Contact Desc, U2.Same_As_Students_Address Desc,u2.lives_with DESC,U2.Guardian Desc)
From Contacts
how to achieve 2 and 3?
The table script is attached. All the above columns are 1 or 0.

Hi,
Please post the table DDLs and insert statements. The rule which you have stated is a bit vague. How are those 5 values stored, insert statements will help us better understand the data.

I am afraid, not everybody like me would like to open/save the attachment. Please post the same thing using [ code] [ /code] tags(without the spaces I mentioned after the braces).
