✅Core SQL Queries You Should Know📊💡 1️⃣ SELECT, FROM, WHERE This is how you tell SQL what data you want, where to get it from, and how to filter it. 👉 SELECT = what columns 👉 FROM = which table 👉 WHERE = which rows Example: SELECT name, age FROM employees WHERE age > 30; This shows names and ages of employees older than 30. 2️⃣ ORDER BY, LIMIT Use when you want sorted results or only a few records. 👉 ORDER BY sorts data 👉 LIMIT reduces how many rows you get Example: SELECT name, salary FROM employees ORDER BY salary DESC LIMIT 3; Shows top 3 highest paid employees. 3️⃣ DISTINCT Removes duplicate values from a column. Example: SELECT DISTINCT department FROM employees; Lists all unique departments from the employees table. 4️⃣ BETWEEN Used for filtering within a range (numbers, dates, etc). Example: SELECT name FROM employees WHERE age BETWEEN 25 AND 35; Shows names of employees aged 25 to 35. 5️⃣ IN Use IN to match against multiple values in one go. Example: SELECT name FROM employees WHERE department IN ('HR', 'Sales'); Shows names of people working in HR or Sales. 6️⃣ LIKE Used to match text patterns. 👉 % = wildcard (any text) Example: SELECT name FROM employees WHERE name LIKE 'A%'; Finds names starting with A. 💬Double Tap ❤️ if this helped you!
