Deleting Duplicated Records
I am new to MySQL and I have a test database that I am playing with. Through an accident while playing around, I ended up with two identicle records in the database. I did a filter to try and change just one of them but both would come up, so I couldn't see how I was supposed to delete just one of the two records. In the end, I deleted both records and re-input the one I needed but I know that there must be a better way of doing this. Perhaps having a column in my database with a serialized, unique record number would be a way to prevent this in the future?

Re: Deleting Duplicated Records
You are 100% correct. Since MySQL does not support cursors, I always put an auto_increment column in my tables for just this purpose. (This is what other DBMS' do, they just do it behind your back) You're right. I use DBase IV at work and every record has an internal record number. Unfortunately, the way MySQL really handles result sets doesn't lend itself to simply adding a hidden auto_increment field to each row to act as a cursor and allow updating of rows in result sets. If it did, then I'm sure they would have put cursor support in the product already.

MySQL Home Uses
I have started using MySQL because I want to learn about something new and to keep a database of my growing comic book collection, which would be handy should something should ever happen to them. In doing this, I have started to think of other ways to use MySQL, such as managing my CD collection and other such things. What I would like to hear is how other people are putting MySQL to work in their home environment. I searched Google for this but turned up nothing, and hearing about what other people are doing often motivates me. If you don't want to reply on list, feel free to email me instead.
