I just finished reading Carl Safina's Beyond Words. It is the latest of a number of books (another great one is Out on a Limb by Ben Kilham) I have read that make it clear beyond any reasonable doubt that the individuals of many, many other species, including bears, octopuses, gorillas, chimpanzees, bonobos, crows, are turtles are self-aware; feel pain, sadness, joy; fear death; play; have individual personalities; work with tools; on and on and on.
Even though a space is a regular character, the client didn't want spaces at the beginning or end of a string. Any spaces in the middle were fine. Of course this could be handled by the application, but it must also be implemented in the database. Using a check constraint with a regular expression will prevent the end user from entering unwanted data.

"I eat using Uber-Eats.I push a button, the food is made, the driver delivers it to me. But when it's fully autonomous, how does the food actually get to my door?

As does seem to occur from time-to-time, I’m out there in the weeds again and sorting out a solution that fits a customer’s need. They wanted to know if they could write Oracle EBS 12.2 Concurrent Manager Programs in Ruby. They don’t want to write Java.
You all know Oracle OpenWorld, right? It's a behemoth of a conference filling up the streets and hotels of San Francisco with many thousands of people moving like ants between conference rooms, checking out exhibitors, hanging around lounging areas, networking, talking, listening, eating, drinking, learning and having fun. And it happens every year...
A question popped up, which I thought was interesting. How can you create a DB_LINK in Oracle without the DBA changing the tnsnames.ora file? It’s actually quite easy, especially if the DBA sets the TNS address name the same as the instance’s service name or in older databases SID value.
