Question

I am trying to figure out how to insert the same value into the entire column of a table? The table already exists and I have an empty column into which I would like to insert a certain value, for example, today’s date. I have only found sources explaining how to insert values into an entire row.

Answer 1

UPDATE myTable SET myColumn='newValue'

newValue can also be an expression.
