SQL Interview Questions with Answers 1. How to change a table name in SQL? This is the command to change a table name in SQL: ALTER TABLE table_name RENAME TO new_table_name; We will start off by giving the keywords ALTER TABLE, then we will follow it up by giving the original name of the table, after that, we will give in the keywords RENAME TO and finally, we will give the new table name. 2. How to use LIKE in SQL? The LIKE operator checks if an attribute value matches a given string pattern. Here is an example of LIKE operator SELECT * FROM employees WHERE first_name like ‘Steven’; With this command, we will be able to extract all the records where the first name is like “Steven”. 3. If we drop a table, does it also drop related objects like constraints, indexes, columns, default, views and sorted procedures? Yes, SQL server drops all related objects, which exists inside a table like constraints, indexes, columns, defaults etc. But dropping a table will not drop views and sorted procedures as they exist outside the table. 4. Explain SQL Constraints. SQL Constraints are used to specify the rules of data type in a table. They can be specified while creating and altering the table. The following are the constraints in SQL: NOT NULL CHECK DEFAULT UNIQUE PRIMARY KEY FOREIGN KEY React ❤️ for more

This is a quick and easy guide to the four main categories: Supervised, Unsupervised, Semi-Supervised, and Reinforcement Learning. 1. Supervised Learning In supervised learning, the model learns from examples that already have the answers (labeled data). The goal is for the model to predict the correct result when given new data. Some common supervised learning algorithms include: ➡️ Linear Regression – For predicting continuous values, like house prices. ➡️ Logistic Regression – For predicting categories, like spam or not spam. ➡️ Decision Trees – For making decisions in a step-by-step way. ➡️ K-Nearest Neighbors (KNN) – For finding similar data points. ➡️ Random Forests – A collection of decision trees for better accuracy. ➡️ Neural Networks – The foundation of deep learning, mimicking the human brain. 2. Unsupervised Learning With unsupervised learning, the model explores patterns in data that doesn’t have any labels. It finds hidden structures or groupings. Some popular unsupervised learning algorithms include: ➡️ K-Means Clustering – For grouping data into clusters. ➡️ Hierarchical Clustering – For building a tree of clusters. ➡️ Principal Component Analysis (PCA) – For reducing data to its most important parts. ➡️ Autoencoders – For finding simpler representations of data. 3. Semi-Supervised Learning This is a mix of supervised and unsupervised learning. It uses a small amount of labeled data with a large amount of unlabeled data to improve learning. Common semi-supervised learning algorithms include: ➡️ Label Propagation – For spreading labels through connected data points. ➡️ Semi-Supervised SVM – For combining labeled and unlabeled data. ➡️ Graph-Based Methods – For using graph structures to improve learning. 4. Reinforcement Learning In reinforcement learning, the model learns by trial and error. It interacts with its environment, receives feedback (rewards or penalties), and learns how to act to maximize rewards. Popular reinforcement learning algorithms include: ➡️ Q-Learning – For learning the best actions over time. ➡️ Deep Q-Networks (DQN) – Combining Q-learning with deep learning. ➡️ Policy Gradient Methods – For learning policies directly. ➡️ Proximal Policy Optimization (PPO) – For stable and effective learning.

When you’re in an interview, it’s super important to know how to talk about your projects in a way that impresses the interviewer. Here are some key points to help you do just that: ➤ 𝗣𝗿𝗼𝗷𝗲𝗰𝘁 𝗢𝘃𝗲𝗿𝘃𝗶𝗲𝘄: - Start with a quick summary of the project you worked on. What was it all about? What were the main goals? Keep it short and sweet something you can explain in about 30 seconds. ➤ 𝗣𝗿𝗼𝗯𝗹𝗲𝗺 𝗦𝘁𝗮𝘁𝗲𝗺𝗲𝗻𝘁: - What problem were you trying to solve with this project? Explain why this problem was important and needed addressing. ➤ 𝗣𝗿𝗼𝗽𝗼𝘀𝗲𝗱 𝗦𝗼𝗹𝘂𝘁𝗶𝗼𝗻: - Describe the solution you came up with. How does it work, and why is it a good fix for the problem? ➤ 𝗬𝗼𝘂𝗿 𝗥𝗼𝗹𝗲: - Talk about what you specifically did. What were your main tasks? Did you face any challenges, and how did you overcome them? Make sure it’s clear whether you were leading the project, a key player, or supporting the team. ➤ 𝗧𝗲𝗰𝗵𝗻𝗼𝗹𝗼𝗴𝗶𝗲𝘀 𝗮𝗻𝗱 𝗧𝗼𝗼𝗹𝘀: - Mention the tech and tools you used. This shows your technical know-how and your ability to choose the right tools for the job. ➤ 𝗜𝗺𝗽𝗮𝗰𝘁 𝗮𝗻𝗱 𝗔𝗰𝗵𝗶𝗲𝘃𝗲𝗺𝗲𝗻𝘁𝘀: - Share the results of your project. Did it make things better? How? Mention any improvements, efficiencies, or positive feedback you got. ➤ 𝗧𝗲𝗮𝗺 𝗖𝗼𝗹𝗹𝗮𝗯𝗼𝗿𝗮𝘁𝗶𝗼𝗻: - Talk about how you collaborated. What was your role in the team? How did you communicate and contribute to the team’s success? ➤ 𝗟𝗲𝗮𝗿𝗻𝗶𝗻𝗴 𝗮𝗻𝗱 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁: - Reflect on what you learned from the project. What new skills did you gain, and what would you do differently next time? ➤ 𝗧𝗶𝗽𝘀 𝗳𝗼𝗿 𝗬𝗼𝘂𝗿 𝗜𝗻𝘁𝗲𝗿𝘃𝗶𝗲𝘄 𝗣𝗿𝗲𝗽𝗮𝗿𝗮𝘁𝗶𝗼𝗻: - Be ready with a 30 second elevator pitch about your projects, and also have a five-minute detailed overview ready. - If there’s a pause after you describe the project, don’t hesitate to ask if they’d like more details or if there’s a specific part they’re interested in. By preparing your project details thoroughly and understanding what the interviewer is looking for, you can talk about your experience in a way that really showcases your skills and increases your chances of getting the job.
