SQL is the key to unlocking the secrets hidden within your database. SQL, or Structured Query Language, is a powerful tool that allows you to retrieve, manipulate, and analyze data. Whether you're a seasoned data analyst or just starting your journey, this blog is here to equip you with essential SQL tips to conquer your data challenges.

Conquering The Basics
Mastering SELECT: This fundamental command is the cornerstone of retrieving data. Learn to filter results using WHERE clauses, sort effectively with ORDER BY, and combine datasets with JOINs.
Unleashing the Power of WHERE: Don't just retrieve everything! WHERE clauses allow you to target specific data based on conditions. Explore logical operators (AND, OR, NOT) and comparison operators (=, &lt;, &gt;) for precise control.
JOINing the Tables: Databases are rarely isolated entities. JOINs allow you to combine data from multiple tables based on shared fields. Explore different JOIN types (INNER, LEFT, RIGHT, FULL) to answer complex questions.All Rights Reserved

VICENZO by TheWalnutTree

Raised in the Mafia, I have known no other life other than cold calculated violence and discipline. A life where brutality is praised and weakness is ridiculed, I became the best of my parents and the worst the world has ever seen. Young and still gaining control of my mafia, love is never an option for me, that is until one night at a Mafia ball where I spy a woman who has me to my knees. I want more, more, more. She's reckless and cunningly beautiful. Too good for me and yet the only one for me. We fight for survival and for each other because neither one of us will let go. ------------------------- I sat in the back, legs apart and looked at her with my head tilted. She licked her lips and squeezed though the front seats all the while looking at me. I pulled her towards me and she chuckled as she sat on my lap. Her legs were either side of me and her breathing was ragged. I ran my hand down her cheek and pulled her into me. I kissed her lips and soon our tongues whirled around. Hungry and rough. She held her head back and I began to plant rough kisses onto her beautiful neck. "Am I a bad influence?" She breathed. Her hands were on the back of my neck. I stopped kissing her and looked up at her. "Everyone needs a little bad in their lives." I whispered back making her smile. My hands found her waist and I noticed her short dress had ridden up exposing her thighs. She wore it to tease me and I loved it. Fuck, I loved her body. She breathed into my neck and I pulled off her dress in one slick motion. My hands were all over her back, feeling her, touching her. Her soft skin drove me crazy. ------------------------- BE AWARE: Trigger warnings: MATURE CONTENT 18+ (SMUT) SWEARING VIOLENCE/GUN VIOLENCE SELF HARM/SUICIDE (REFERENCES) EXPLICIT LANGUAGE REFERENCES TO RAPE SMOKING/ALCOHOL/DRUGS BLOOD/DEATH/GORE ©️ All rights reserved ™️ The Walnut Tree BOOK TWO OF THE MAFIA SERIES

The Follower by LateNightStories12

Life has evolved and more technologies appeared. The internet is the main brain of these technologies, but that doesn't mean that it's safe. It is said that we are only using 10% to 15% of the entire internet, so where is the left of it that's the question. That's not the main point the point is how people could use the internet. Some could use it for social life, some could use it for doing research and some could use it to track you down and know every single move you do. They could hear everything, know your next destination. Maybe now you're being followed and tracked down by someone but you just don't know. Just as the characters in the story. The story is based on possible events that could occur in these days. Nobody knows what's out there on the internet, and what's in people's minds. Beware the internet, beware of the people around you, beware of the people you give trust to, beware of the mysterious follower that stalks you that is obsessed with you without you knowing. * Story chapters will be published one by one as a tv series to make the reading part easier and give more excitement to what's coming* Thanks for reading.

I said lightly trying to pull away but he tightened his hands on my throat enough to keep me in place he leaned in close enough that his lips were grazing against mine yet he didn't let them touch. "You think I'm going to let you go after getting a taste of you mhm? Oh baby I'm no where near done with you."

Betrayal Codes by bookwrm66

Four girls from a secret society. Three deep-undercover delinquents. One race to shut the criminals down. Four of the very best teenage agents from a secret society are sent to a faraway country. Their mission: Find and capture the leader of the Band of Crime, a group of delinquents famous for their international robberies, kidnappings, and vandalisms. Once captured, they must return the leader to the agency before the Band catches them. The problem: They have no idea where the leader is or how to stop him. But these girls are the best agents out there! They've got this! Or do they... The girls' skills and trust are questioned when they team up with a group of boys who are weirdly good at cracking the Band's codes - and are pretty hot. Little do they know, those boys are the Band's best agents. Once they find out, will it be too late to stop the boys from ruining all their plans? - - - TW: Emotional, mental, verbal, and physical abuse; mentions of murder, incarceration, kidnapping, and child abuse; gangs, organized crime, threats/torture, PTSD, guns, brief scenes with blood, and explicit language.

Archeia's Atheneum (The First Shift) by nullandvoid44

You're awake. You're different. You exist, suddenly, as two things. You, the one you know, with the body and name you're familiar with--and this new you, the one exists within you. This you is inhabiting a world within your own. This other consciousness that you see through has begun to sense its timeline, each word a moment. Like the you you're familiar with, this self seems to come into its life mid-story--though the way you experience this life/story differs vastly from what you're used to. As you grow you will eventually know how to articulate it, even recreate it. First, however, you must choose to embark on/in this small incarnation; you must read the first word. For those who will tread forth on this journey, we salute you. You have been dubbed Archeia, may your journey be ever abundant.
