    Very new to sql but trying to figure out if i can use sql to select just values in column "Ctrl" that start with "R".

     

    In this data set all i need is the "R-######" and nothing else but cant figure out how to get it. Any help would be much appreciated. Thank you!

     

    See attached for data table

    LEFT is never SARGable.  LIKE is SARGable if the pattern begins with a constant.

    If you specifically want "R-" followed by 6 digits, you could do:

    YourColumn LIKE 'R-[0-9][0-9][0-9][0-9][0-9][0-9]'
