oh right? not tried 2019 yet.. i'm bit relucant to change, only styarted using 2017 like a year ago, before that was using 2012 / 2015 for years.
i have a question about c# / JSON, but not sure if i'm in the right place? i.e do you allow questions here or is this a channel for other things?
@Kevincryto. Are you about sir?
i.e if you replace the null with an actual date and run the query again, does it work?
so this is a web project? sorry thought it was a desktop application.
have you tried simply "null" instead of DBNull.Value ?
have you tried DBNull.Value.ToString() ?
.. if you can spare a couple of mins may i pm you?
do you have update permission to the table ?
hmmm, did you select a folder ?
why dont you have visual studio?
