Iterate results update records

Iterate results update records

(OP)
Hi Guys can you help with coming up with a query.
I update this table daily by crawling a website each day with vehicle details .
What i need is if a registraion is missing for a day I want to update VehicleSOLDDate with the latest datetime for that missing registraion ?

using SQL server 2012

registraion | Datetime |VehicleSOLDDate
abc def |01/01/2017 00:00 |
aaa bbb |01/01/2017 00:00|
abc def |02/01/2017 00:00|
aaa bbb |02/01/2017 00:00|
abc def |03/01/2017 00:00 | 03/01/2017
aaa bbb |03/01/2017 00:00|
aaa bbb |04/01/2017 00:00 |

RE: Iterate results update records

You need to keep a copy of the previous day's query. Then use a MINUS or NOT IN query to find all records that are in yesterday's data, but not in today's.
