Hi:

 

I have my hosting from GODaddy, and my making tables in mySQL for my small CMS that I use to edit the page content.

 

I have what I think is a error messgae "No index defined" (see attached .JPG).

 

What does this mean? Do I have to define this? The CMS works fine.

All it does is update the fields.

If you wanted that table to work in relation to another, the proper field would need an index, for example, a primary key already has an index. Indices work just like they do in the back of a textbook, they help find information faster. So if you're selecting something by it's ID constantly, you may want to make that an index if it's not already.
