(the SQL table exists because of a manual import to SQL from the original Excel spreadsheet, has a primary key set.The user updates the excel sheet and I need to update the SQL values.) I am setting the dt.
I suspect what you want is "Ad Criteria Key" behaviour.
Row State to modified in an effort to invoke the Update. (Previous test show my SQL permissions and connection is good, I can modify the table.) connection To SQL = new Sql Connection(SQLConn String); connection To SQL.
Open(); var cmd = new Sql Command("SELECT * FROM TAGS$",connection To SQL); var da = new Sql Data Adapter(cmd); var b = new Sql Command Builder(da); foreach (Data Row r in dt. Update(dt); It's difficult to tell what is being asked here.

So I iterate through it to set the rowstate to modified to invoke the Update command to work on the table. So my issue is the update command is not doing anything even though I have set all the rows to "Modified".
(I could paste all the Import Excel code here but it is a lot and doesn't do anything except Fill a dt with everything in a sheet.
Thanks for the clarification - I already got that though, but my point is you're changing the backing store of all of those rows implicitly.
