    I have a script and would like to estimate how much time it will run. How to do it?

    Many thanks in advance.

    at least viewing the estimated execution plan would give you a ballpark number;

    Where 'ballpark' is the size of half a continent. 🙂

    Run the script in a test environment with roughly the same amount of data. There's your time estimate.

    Neither the estimated nor actual execution plans contain durations, estimated or actual. They contain estimated costs (which can be so far off as to be useless) and costs are not times.
