Nevermind...

I re-ran the query and extract just after I posted this.

The results were perfect. No clue what happened before.

Sorry for the noise.

------------------ ORIGINAL ----------------
This morning I exported a larger query result to a CSV file, 460 MB
worth. Imagine my surprise when all the characters after a bit over 93 million bytes were NULL characters!

It was around row 58,673.

PSD said it exported 280,843 rows, so that's a lot of nothing/NULL in the file!

Have I hit some known limit for this feature or is this not expected behavior?

I'm running PL/SQL Developer V13.0.6.1911

Thanks in advance...
