I have a table with a basic structure... column1, column2, column3.
When I upload to this table on phpmyadmin (or any other environment for that matter), I would like to be able to add a fourth column which is a concatenation of the three columns being uploaded.
Is there any way of creating a column which is the equivalent of CONCAT(column1, column2, column3) as column4
so that each time I import to this table, column4 will be populated automatically?
I'm trying to avoid having to do this work before import or after, which I presume would require creating an additional table.
Any help would be appreciated.
Cheers, Ste
