Ruby on Rails Friday, April 30, 2010

I'm not sure if this answers your question in regards to your specific example, but let's say you have a simple table with just two numerical columns, say two integers.

SELECT i1, i2, i1+i2 AS "Sum" FROM MyTable
will show three columns, two of them real columns from the table and one computed.

So the term in this case is a COMPUTED column.

Best regards,
Rolf

Hi,

thank you for reading my post. I've got s simple question: What's the
correct technical term for data which IS NOT calculated and data which
IS calculated regarding database design.

Simple example: saving a user message in a corresponding table vs.
counting all messages of a user.

If you also know the german expressions, you're welcome to post them,
too. :)

Thanks for your help,
ms
