DateTime Concatenation Upload Images   Link   Austin Ritner  2 years ago Could I concatenate a field consisting of how many days have passed since January 1st of that year, the current date/time and autonumber? For example: 1/5/20 at 12:34:56 PM, and autonumber 12 Could I get that to display as 000412345612? Richard Rost 2 years ago Sure. I don't see why not. Use DateSerial to put together 1/1 of the current year. Use DateDiff to determine how many days from then until now. Use Format to assemble the current date/time as you want it. Then smash em all together. :) Austin Ritner 2 years ago I'll give it a try later and let you know. Richard Rost 2 years ago Remember, you can do it all in one statement, but it's easier if you break it down into steps. Austin Ritner 2 years ago Gotcha. Haven't quite learned about dateserial yet so that will be interesting. Formatting it should be either in the format tab or maybe an input mask with all numbers? I'm thinking this could be an alternative to an OrderID and would probably only show on an invoice or paid orders. Richard Rost 2 years ago Just use the Format function. If you finish this entire class and still have questions, let me know. DateSerial is a great function. Austin Ritner 2 years ago Finally had some time to really work on this. It was super easy. The only thing I had an issue with at first was formatting the time because it was displaying the AM/PM, but as soon as I put Format([Time], "hhnnss") into the control source tab, it worked flawlessly. So now it displays as days passed since 1/1, mmddyy, hhnnss, and autonumber (293)-(090920)(093342)(1) Richard Rost 2 years ago Awesome! Sorry, only students may add comments.
