Hello all!
I've come here since I have this problem where using the SharePoint Output Tool to write a YXDB file, comes out with 0 rows but oddly has all columns used.
And if I try CSV file, it writes as it supposed to be without any problem.
This is my Workflow at the very end:
Here I have around 1.3 M records, as well with the Output name that, depending on the date, will change the Suffix.

And here is the options used for the YXDB file:


I have the same options to write a file on the CSV Output that will use the column "Output" to change the name. But no matter what options I use, the file comes out with all column names and 0 rows.


I hope this has a Solution, since using the Output Tool and waiting for OneDrive to upload the file is very slow.
