Following is the empdetails table in my organization which has been used for last 3 years.
create table Empdetails(empid int , empname varchar)
We noticed that there was no primary key and now we are looking for transactional replication to replicate this data. How can I create primary key on this table. According to my understanding the primary key can be created only when the table is created. Do I need to create a dummy table and then transferring data, rename this table as Empdetails after dropping the original table?

Check if you have an unique index on empid column...
if yes then build your PK on it.
if no then check for and fix empid duplicates then build your PK on it.
