Here are some essential SQL tips for beginners 👇👇 ◆ Primary Key = Unique Key + Not Null constraint ◆ To perform case insensitive search use UPPER() function ex. UPPER(customer_name) LIKE ‘A%A’ ◆ LIKE operator is for string data type ◆ COUNT(*), COUNT(1), COUNT(0) all are same ◆ All aggregate functions ignore the NULL values ◆ Aggregate functions MIN, MAX, SUM, AVG, COUNT are for int data type whereas STRING_AGG is for string data type ◆ For row level filtration use WHERE and aggregate level filtration use HAVING ◆ UNION ALL will include duplicates where as UNION excludes duplicates  ◆ If the results will not have any duplicates, use UNION ALL instead of UNION ◆ We have to alias the subquery if we are using the columns in the outer select query ◆ Subqueries can be used as output with NOT IN condition. ◆ CTEs look better than subqueries. Performance wise both are same. ◆ When joining two tables , if one table has only one value then we can use 1=1 as a condition to join the tables. This will be considered as CROSS JOIN. ◆ Window functions work at ROW level. ◆ The difference between RANK() and DENSE_RANK() is that RANK() skips the rank if the values are the same. ◆ EXISTS works on true/false conditions. If the query returns at least one value, the condition is TRUE. All the records corresponding to the conditions are returned. Like for more 😄😄

✅ Top Data Analytics Interview Questions with Answers – Part 1 🧠📈 1️⃣ What is the difference between Data Analytics and Data Science? Data Analytics focuses on analyzing existing data to find trends and insights. Data Science includes analytics but adds machine learning, statistical modeling predictions. 2️⃣ What is the difference between structured and unstructured data? • Structured: Organized (tables, rows, columns) – e.g., Excel, SQL DB • Unstructured: No fixed format – e.g., images, videos, social media posts 3️⃣ What is Data Cleaning? Why is it important? Removing or correcting inaccurate, incomplete, or irrelevant data. It ensures accurate analysis, better decision-making, and model performance. 4️⃣ Explain VLOOKUP and Pivot Tables in Excel. • VLOOKUP: Searches for a value in a column and returns a value in the same row from another column. • Pivot Table: Summarizes data by categories (grouping, totals, averages). 5️⃣ What is SQL JOIN? Combines rows from two or more tables based on a related column. Types: INNER JOIN, LEFT JOIN, RIGHT JOIN, FULL JOIN. 6️⃣ What is EDA (Exploratory Data Analysis)? It’s the process of visually and statistically exploring datasets to understand their structure, patterns, and anomalies. 7️⃣ Difference between COUNT(), SUM(), AVG(), MIN(), MAX() in SQL? These are aggregate functions used to perform calculations on columns. 💬 Tap ❤️ for Part 2
