Is there any obvious performance difference between updating 1 column in a 4 column wide table vs 1 columns in a 1000 column wide table ?
I have a table with 4 columns and 10 million rows in which I want to update 1 column
I have another table with 100 columns and 10 million rows in which again, I want to update 1 column.
Which one among these 2 would perform better.
