I have a query that pulls parent login info and insert into another table.

I want to select unique records based on uique ParentEmail column.

Because we use ParentEMail as login name they have to be unique.

So my select query has below columns:
select familyID, ParentEmail, Parentpassword, Adusername, Adpassword, firstname, lastname, nameID
from tblParents

How can I modify the above query, that if there are duplicated Parent email, I will only pull the first record so this way, all the records will be unique based on ParentEmail column?

Thanks

;with CTE as
(select familyID, ParentEmail, Parentpassword, Adusername, Adpassword, firstname, lastname, nameID,
row_number() over (partition by ParentEmail order by familyID) as Row
from tblParents)
select *
from CTE
where Row = 1;



Will that give you what you need?
