[snip] I'm working through (my first day) PHP & MySQL for Dummies and I'm stuck on the primary field for my database. I want to create a racing pigeon results database that has 6 fields only. The results will be imported into the database in bulk from a CSV file Owner - GBring - Ering - Arrivedtime - date - position
If I'm not wrong, surely whichever one of the first 3 fields I create as a primary field will stop me entering any races after the first one, because every race thereafter will always for the most part be the same owners and rings. So do I have to have a primary key? [/snip] You do not, but it is bad database design. The simplest (but not necessarily best) thing to do is add an auto-increment column and declare it as your primary key. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
