Hey,

I have three fields in a MySQL db, Name, Date, and Hour.

Right now there is no last name field and now since im into more of this perl web data application, I want to start sorting by last name.

The db is currently has 5000+ data entries. What would be the best most efficient way to create a last name field with all the values according to the Name field.

such as:

Name          Date       Hour    <br>
Bob Jones    11/02/83    5<br>
John Doe     11/03/83    4<br>

I was thinking about, putting all those names into an array, then use a foreach statement to split the names up so I could retrieve the last name. Once splitten up, put those values into a array, then use mysql commands to add a new column and insert the values accordingly.

Finished result (ex.):

Name       Last       Date       Hour    <br>
Bob Jones  Jones    11/02/83    5<br>
John Doe   Doe      11/03/83    4<br><br>
