| I'm designing a database and was researching common conventions and standards. I found that some people don't use the identity column for a primary key because they prefer to create their own unique id number for the column. Whats your opinion?Ryan |

| It depends on the data. If you have unique data in your table you might as well use that for PK. If you cannot establish a uniqueness, then you can go for an IDENTITY column.Dinakar Nethi************************Life is short. Enjoy it.************************http://weblogs.sqlteam.com/dinakar/ |
