I am trying to calculate a live hits per minute by machine based on total parts ran per the difference between the start time of the day and the most recent timestamp. I am having trouble piecing together the correct formula to go about this. Does anyone have any suggestions? Thanks

    You could utilize the unix_timestamp function which will convert your timestamp columns into the number of seconds since 1970. This will make both fields integers, so you can do basic math to subtract the two to find the number of seconds and then divide by 60 to get the number of minutes. You can then use that number against your total part ran to get the number per minute.

    @MarkSnodgrass Worked great! Thanks you for your help on this. If I was to use a rank and window to get start of day and most current of day how would I format that rank? rank by row number, timestamp descending?


    Thanks
