Hi, I have a database, which was till now, not having any primary key defined. I thought I would not need it but now I think I do (based on the suggestions from my prior postings). I am now trying to insert the primary key in an already existing database. There was not even an index defined earlier (sorry, if it looks strange). There are many columns that have same names this means that I cannot make that column the primary key. I have now got an idea to first define index on the table and then make the index thing the primary key. I have mySql on cPanel. please advice how to achieve this on an existing database in cPanel php admin. Any link or steps would help. I tried it myself but there is something it wants to tell me, that I am not sure about.
