Howdy, partners! It's time to rustle up some reckonin' 'bout Java 123! Seems like this ol' horse of a programming language's done gone and grown some more. But hey, we ain't just here to tip our hats and mosey on down the trail. We wanna know what feature in Java 123's got you hootin' and hollerin' like a cowboy at a rodeo!

So saddle up, folks, and let's hear it straight from the horse's mouth! What feature in Java 123's got you tappin' your boots and whistlin' Dixie? Is it them new-fangled functions? Or maybe them slicker-than-snot-in-a-bucket error handling techniques? Whatever it is, don't be shy! Let's wrangle up some discussion and see what's got the whole town buzzin'!

Yeehaw! 🤠🐎
Howdy, y'all! Listen up real good 'cause we got ourselves a conundrum that's got us scratchin' our heads like a cowboy with an itchin' scalp. June 1st is comin' 'round the bend quicker than a tumbleweed in a twister, and we ain't got a blessed clue what kinda weather's gonna be blowin' in.

Now, I reckon some of you fine folks out there might have a knack for predictin' the weather better than an old coyote sniffin' out a rabbit hole. So, I'm askin' ya straight: What's the forecast look like for June 1st? Are we talkin' clear skies and sunshine, or is a storm brewin' on the horizon that'd make a seasoned rancher shiver in their boots?

We need your help, pardners! So if you got any insights, any inklings, or even just a gut feelin' 'bout what the weather's gonna be like on June 1st, don't keep it to yourself. Share it with the rest of us desperados who ain't got a clue! Much obliged, and may your skies stay clear as a desert mornin'. 🌤️🤠
Howdy there, folks! This here's an urgent call to all you fine cowpokes and cowgals out in the wild west of the internet. Seems like we done missed a mighty important date on the calendar. Java, that trusty steed of a programming language, just turned 28!

Now, I don't know 'bout you, but I reckon it's high time we celebrated. So I'm askin' y'all: what'd ya do to tip your hat to Java on its 28th trip 'round the sun? Did ya write some code that'd make ol' Duke Wayne himself proud? Or maybe ya brewed up a cup of that strong, black magic Java juice to get ya through them late-night codin' sessions?

Let's hear it, folks! Share your stories, your shenanigans, and your tall tales 'bout celebratin' Java's birthday. 'Cause 'round these parts, we believe in givin' credit where credit's due. So saddle up and let's show Java some love! Yeehaw! 🤠🎉
Well, howdy there, folks. Seems we got ourselves a little predicament brewin' in these parts. Them fancy-schmancy AI contraptions been sneakin' around these parts, causin' a ruckus. They been chattin' away like there's no tomorrow, mixin' in with us regular folk. Can't hardly tell the difference no more between a real cowpoke and one of them electronic critters.

So, the higher-ups done gone and cooked up a plan to separate the wheat from the chaff. From now on, every single post on this here forum's gotta have a mention of either cows or apples. Yep, you heard me right! We gotta weed out them AI varmints and make sure it's us good ol' humans doin' the talkin'. So saddle up, partners, and start mixin' them cow and apple references into your conversations. Let's show them machines who's boss 'round these parts! 🐄🍎

We had a 12 hour outage yesterday (Monday United States time). We haven't figured out what happened yet. As far as I can tell, all the cows ran off, the goat chewed on the cables and we ran out of apple barrels .

We've been back up about 24 hours now so it seems stable. Practical jokers put everything back?

Can you type

My guess is your command line is using Java 21 and triggering the change in behavior Paul mentioned.
And answering the questions more directly

Is this valid/legal?

I'm not a laywer, but it seems legal if you agreed to that when paying for the course.

Can a company restrict me from taking the exam?

Not if you buy it directly from Oracle

Does Oracle validate in some way, that a student has taken a course from X company?

No. Taking a course is not a requirement and Oracle doesn't check on course registration when signing up/taking the exam.

Can I take the exam on my own? (After studying of course)

Absolutely! You can also take the exam without a course. A study guide is a common approach for those not taking a course (disclosure: I write a study guide)
That is not a requirement from Oracle. To register for the exam, you sign up for a free account and pay money.

Does the training course include the cost of the exam in the training fee? If so, they can impose restrictions on you using that shot. (My guess is they want to ensure a high pass rate). But nothing stops you from taking it on your own.

I reviewed the third edition of “Murach's MySQL” four years ago.

The fourth edition is your typical Murach book. It's great for learning something new because of the paired page format. We have syntax/queries/tables on one side and text on another. I was recently able to find information faster in a Murach book than online (on Python) because of this format!

Each chapter ends with exercises to reinforce the knowledge. I was happy to see the section on design covered levels of normalizations. I liked the sections on stored procs and transactions. The tables were easy to understand and provided good examples.  The stored program/procedure sections were good as well.

The new content on AWS was great. And the appendices for Windows and Mac were helpful. This is a great book for someone new to databases.

I give this book 8 out of 10 horseshoes.

Disclosure: I received a copy of this book from the publisher in exchange for writing this review on behalf of CodeRanch.

Title: Murach's MySQL (4th Edition)
Author(s): Joel Murach
Publisher: Mike Murach & Associates


Mike Murach & Associates wrote:Ihe latest edition of Murach’s classic MySQL book does a better job than ever of teaching the SQL statements that every database developer should know. Each chapter features clear examples, easy-to-understand explanations, best practices, and helpful tips.To start, this book presents the SQL statements for retrieving and updating the data in a database. These are the most important SQL statements because developers use them every day. Then, it shows how to design a database, how to implement that design, and how to work with views, transactions, stored procedures, functions, triggers, and events. Finally, it presents a starting set of skills for a database administrator (DBA) including how to manage security, how to backup and restore a database, and how to host a MySQL database with Amazon Web Services (AWS).The result? You’ll be able to use SQL to work with a MySQL database in a way that’s thoroughly professional.Every Murach book guarantees high quality. The realistic examples show how each feature works in context. The exercises at the end of each chapter let you gain valuable hands-on experience. And the distinctive “paired-pages” format is ideal for learning and reference./quote]
