"It Depends". What is it that you're trying to ALTER on every table?

--Jeff Moden

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

Hi Jeff. I suppose I would become an automation project actually. Needs kinda data analytics /machine-learning. The script has to read the contents of the column and analyze basing on the Max / Min / Avg values and how the data is distributed and then suggest a length /Type and generate alter command . for each column where applies. On a smaller scale , similar lines ,I'm building something that projects Index Rebuilds/Reorganize for all objects based on an algorithm (counting number of table cols , Index cols / Row Count etc ) that determines the fill factor .
