Insert Unique Value in MS SQL Database By Using SQL Stored Procedure

When we enter some data in database then its repetition is major problem for at all. Here I am using a table with Mobile No. as primary key and trying to insert unique value to it.

You can see database in this image.
 
Stored procedure wants phone no as a parameter which can be passed easily

create procedure insert_unique
(
@phone numeric(10,0)
)
as
begin
INSERT INTO PhoneData(Phoneno)
    SELECT @phone
WHERE NOT EXISTS (SELECT phoneno FROM PhoneData WHERE Phoneno = @phone)
end

Pass your phone no in this procedure and it will insert only unique record.
