You have some data.
You want to email it to someone.
You don’t want them to have to open an attachment.
You want it to be in an HTML-Tabl’ish delivery device.
In SQL Developer, write your query.
Export to HTML > File.
Start your message.
Point to your HTML File
DON’T CLICK ON THE INSERT BUTTON
On the INSERT button, there’s a drop-down widget. Click that instead. And then choose, ‘Insert as Text.’
I realize this is a few extra clicks than you might want, but it’s probably still faster than what you’ve been doing.
