Unique and Non Unique Records Using Row Number

$

0

 Hello, 

I have a table which contains id, EmailAddress, Storeid,Rn . The EmailAddreses can repeat using different storeid. The table already has records with Rn ( Row Number()) applied. 

CREATE TABLE #Profile(
id INT IDENTITY (1,1) PRIMARY KEY , 
EmailAddress VARCHAR( 100) NOT NULL, 
Storeid INT NOT NULL, 
Rn INT NOT NULL )

INSERT #Profile(EmailAddress, Storeid, Rn) VALUES ('abc@gmail.com',12,1)
INSERT #Profile(EmailAddress, Storeid, Rn) VALUES ('abc@gmail.com',13,2)
INSERT #Profile(EmailAddress, Storeid, Rn) VALUES ('abc@gmail.com',14,3)

INSERT #Profile(EmailAddress, Storeid, Rn) VALUES ('ac@gmail.com',12,1)

INSERT #Profile(EmailAddress, Storeid, Rn) VALUES ('ab@gmail.com',12,1)
INSERT #Profile(EmailAddress, Storeid, Rn) VALUES ('ab@gmail.com',13,2)
INSERT #Profile(EmailAddress, Storeid, Rn) VALUES ('ab@gmail.com',14,3)
INSERT #Profile(EmailAddress, Storeid, Rn) VALUES ('ab@gmail.com',15,4)

SELECT * FROM #Profile

I want to query the table in such a way that I would get all the emailaddress present only once- ac@gmail.com

Please advice .

Thanks
