DELIMITED text files are popular ways of passing data around.
CSV anyone? The C stands for ‘Comma’ – regardless of what your smug European friends may have told you

Anyways, in SQL Developer, when using the export dialog to get a DELIMITED export for your dataset, you can set the delimiter and the string enclosure for your columns.
Don’t like commas as delimiters? Set your own.
So in the command line interface AKA SQLcl:
The first argument defines the delimiter, the 2nd defines the left enclosure, and the 3rd defines the right enclosure.
So you could have BEER emoji separated values files…
Speaking of SET SQLFORMAT…
Back in October, we made a tweak to the ANSICONSOLE. It’s VERY configurable now in terms of how you want numbers displayed. Don’t miss this awesome post from @krisrice.
