Refresh table in database every week with write back button from Spotfire

[PR Bhat]

I have two tables Table-A and Table-B data tables which is fetched from DB and I am doing some transformation and creating table-C. I want to write back entire Table-C to database from Spotfire on weekly basis, by clicking a button. I saw some information regarding DB table update but those specify updating few columns, In my case I have around 80 columns in the table and I want to update all to database table. If someone is having the solution please help.
