Menggali Lebih Dalam: 5 Fakta Menarik tentang SQL Query

SQL (Structured Query Language) merupakan bahasa pemrograman khusus yang digunakan untuk mengelola dan mengakses basis data relasional. SQL Query adalah perintah atau instruksi yang digunakan untuk berinteraksi dengan basis data. Dalam dunia pengembangan perangkat lunak dan administrasi basis data, SQL Query menjadi landasan utama. Mari kita telaah 5 fakta menarik tentang SQL Query yang dapat memberikan wawasan lebih dalam.

1. Basis Data Relasional dan SQL

SQL Query paling sering digunakan dalam konteks basis data relasional. Basis data relasional menggunakan tabel untuk menyimpan data dan memanipulasinya dengan menggunakan relasi antar tabel. SQL memungkinkan pengguna untuk menentukan, mengakses, dan memanipulasi data dalam tabel-tabel ini dengan mudah melalui Query.

2. DML dan DDL: Perbedaan dalam SQL Query

SQL Query dapat dibagi menjadi dua jenis utama: Data Manipulation Language (DML) dan Data Definition Language (DDL). DML digunakan untuk mengelola data dalam basis data, seperti menambahkan, menghapus, atau memperbarui catatan. Di sisi lain, DDL digunakan untuk mendefinisikan struktur basis data, seperti membuat, mengubah, atau menghapus tabel.

3. Klausa WHERE: Penyaringan Data

Klausa WHERE adalah salah satu elemen kunci dalam SQL Query. Digunakan untuk menyaring data berdasarkan kondisi tertentu, klausa WHERE memungkinkan pengguna untuk mengambil data yang memenuhi kriteria tertentu. Misalnya, SELECT * FROM Tabel WHERE Kolom = Nilai akan mengembalikan baris-baris yang memenuhi persyaratan tersebut.

4. JOIN: Menggabungkan Data dari Berbagai Tabel

JOIN merupakan fungsionalitas penting dalam SQL Query yang memungkinkan pengguna untuk menggabungkan data dari dua atau lebih tabel. Dengan JOIN, kita dapat mengambil data yang berkaitan dari tabel-tabel yang berbeda berdasarkan kolom-kolom yang memiliki nilai yang sama. Ini memungkinkan pengguna untuk membuat kueri yang lebih kompleks dan mendapatkan informasi yang lebih terperinci.

5. Transaksi dan Kepatuhan ACID

SQL Query sering digunakan dalam konteks transaksi basis data. Transaksi adalah serangkaian operasi yang membentuk suatu tindakan tunggal, dan SQL mendukung sifat-sifat transaksi yang dikenal sebagai ACID: Atomicity, Consistency, Isolation, dan Durability. Ini menjamin bahwa operasi-operasi tersebut dapat dijalankan secara aman dan konsisten.

Melalui kekuatannya dalam memanipulasi data dalam basis data relasional, SQL Query menjadi elemen kunci dalam pengembangan aplikasi dan administrasi sistem basis data. Dengan memahami konsep dan fungsionalitas dasar SQL Query, para pengembang dan administrator basis data dapat mengoptimalkan kinerja dan efisiensi operasi mereka.

any changes in the standings for most & least known artists?

Most known (highest percentage "yes") is still the same as it was in February (Queen, ABBA, Lady Gaga, Rick Astley, Smash Mouth).

Least known (highest percentage "haven't heard of") changes more often. Here they are as of June 20 (the last time I updated the data) - all are between 99.4% and 99.2% "haven't heard of":

Everyone on the Internet keeps yelling about holding people accountable and this and that punishment, but they have no interest in improvement. What happened to learning from your bad behaviour and getting better?

I follow an American guy on YouTube who was in prison for 19 years for armed robbery and assault and he seems to have used that time to better himself, to get an actual education and improve as a person. He acknowledges his crimes and that he has to constantly work on himself, but he also invests a lot of time in outreach and helping young incarcerated people so they don't get deeper into the criminal world.

His behaviour at 18 shouldn't be excused, obviously, the incarceration was warranted - and this might be my Scandinavian culture speaking - but I believe in improvement, not punishment for the sake of it. So when I follow that guy, I'm trying to understand him, trying to follow his progress and his circumstances.

Obviously not all crimes are equal, that goes without saying, some people can't improve and are dangerous, some simply don't have the insight to understand what they did wrong, but fundamentally I believe humans can learn to do better and I don't understand why so many people won't let them or don't want them to.

I also believe that there are psychological reasons for most human behaviour, especially if it deviates from well-adjusted social patterns, and I think we benefit from trying to understand these cases rather than condeming them wholesale. We don't have to personally approve of a behaviour to try to understand it.

a character's self-deprication being what keeps them from being in a relationship can be really good but mostly when the self deprication is 1. justified and 2. only no longer an issue because their significant other is Into whatever they're angsting about

I HAVE A FIC IDEA vol#9

• Peter Parker has never been to a doctor, never had his DNA analysed, fingerprints scanned or blood taken. His medical/biological footprint is nonexistent.

• Spider-Man however, has given everyone plenty of occasions to get his DNA. SHIELD, the government and even Avengers know plenty about the organism of a young hero. And yet no one can pinpoint who said young hero is.

• All the more reason why Peter can never leave New York or go to the doctor. Now all he has left to do is explain that to his Aunt without letting on his secret identity.

Bonus; Include the kidnapped bio-dad trope. Imagine if Tony knew his kid was Spider-Man and could not get a hold of him for weeks/months.

wrt the dadson aspect of Vandermorgan I myself kinda denied it at first considering they only have a 8 years age gap but let's be real the daddy issues Are There regardless of that and Dutch took advantage of them in the hottest way. Anyway as one of these 6 people thank you forever and always for making this V/ltron looking ass fandom a little more bearable

Not v💀ltron... now that you say it I see the resemblance. How rdr ended up with an audience of soft-skulled babies is beyond me

Re: The age gap, in the beginning I was disappointed to learn it wasn't that big, but I've learned to enjoy it because it adds another dimension to their 'father-son' dynamic. Dutch still wants to assert himself as an authority figure through his seniority, and imposes this bastardised family structure on others in order to legitimise his control over everyone (beyond just being a 'leader'). It demands that others not only be loyal to his ideals, but makes them emotionally invest themselves in him.

If Dutch was genuinely old enough to be Arthur's dad I don't think his ego could take it, I don't feel it'd have the same impact, rather than knowing Dutch is twisting Arthur's arm to make him submit to this farcical relationship. it has a certain fuckery to it🤌
