DADay 19 SQL: IN vs OR - Beginners LOVE This Hack! 🔥
SAVE this and SHARE it With PEOPLE Who Really Need it
COMPLETE QUERY (copy-paste ready):
SELECT * FROM employees WHERE department = 'Sales' OR department = 'HR';
vs
SELECT * FROM employees WHERE department IN ('Sales', 'HR');
WRONG ❌ WHERE department = 'Sales' OR 'HR'; ← ERROR!
RIGHT ✅ Both queries work! Same result 👇
Method 1️⃣ OR Operator (Logical)
Method 2️⃣ IN Operator (Set Membership)
OPERATORS BREAKDOWN:
• OR = Logical Operator (Sales OR HR)
• IN = Set Operator (department IN list)
• WHERE = Filter clause (works with BOTH!)
EXECUTION ORDER: FROM → WHERE → SELECT
Works in MySQL/PostgreSQL/SQL Server ✅
💡 PRO TIP: Check Day 18 (HAVING vs WHERE) + Day 17 (GROUP BY)
Save Day 19: IN vs OR Operators! 📌
MySQL 7 Operator Types:
1️⃣ Arithmetic: + - * /
2️⃣ Comparison: = > < >= <=
3️⃣ Logical: AND OR NOT
4️⃣ Range: IN BETWEEN LIKE ANY ALL
5️⃣ Bitwise: & | ^
6️⃣ Assignment: += -=
7️⃣ NULL: IS NULL / IS NOT NULL

EN🧠 SQL MCQs That Decide Shortlisting 😳
1️⃣ Which is evaluated first in SQL?
❌ SELECT
❌ WHERE
✅ FROM
👉 Data source is decided first 🔥
2️⃣ Which keyword limits rows in MySQL?
❌ TOP (SQL Server)
❌ ROWNUM (Oracle)
✅ LIMIT
👉 MySQL = LIMIT 😤
3️⃣ COUNT() returns?
❌ Non-null rows
❌ Null rows
✅ All rows
👉 COUNT() counts EVERYTHING 🔥

CHOrder : FROM → JOIN → WHERE → GROUP BY → HAVING → SELECT → ORDER BY → LIMIT
Explanation:
1. FROM ✅
• SQL first decides which tables it will use.
• It loads the data from those tables.
2. JOIN✅
• If your query has joins, SQL will next connect the tables based on join conditions.
3. WHERE✅
• Filters rows.
• Removes rows that do not meet your conditions.
4. GROUP BY✅
• Groups remaining rows into small buckets based on columns.
• Required when you use aggregate functions: COUNT(), SUM(), AVG() etc.
5. HAVING✅
• Works like WHERE, but after grouping.
• Filters groups instead of individual rows.
6. SELECT✅
• Now SQL picks which columns or calculations to show.
• This is where alias names are applied.
7. ORDER BY✅
• Sorts the final result (ascending / descending).
8. LIMIT / TOP✅
• Finally, SQL returns only the requested number of rows.
