SQL Tip Of The Day Use REVERSE() to Flip Strings SELECT REVERSE('SQL'); -- Outputs LQS Niche, but fun and sometimes useful. Ever had to reverse strings? #SQLTips #StringFunctions #LearnSQL

🧠 LIKE helps you match text patterns in columns. Use wildcards: % → any number of characters _ → one character Example 👇 SELECT * FROM Person.Person WHERE FirstName LIKE 'A%'; ✅ Everyone whose first name starts with A. #LearnSQL

📊 Step 3: Filter Ranges with BETWEEN SELECT * FROM Sales.SalesOrderHeader WHERE TotalDue BETWEEN 5000 AND 20000; ✅ Orders with totals between ₦5,000–₦20,000. Works for numbers, dates, and ranges. #learnsql

🧠 Step 1: Remove Duplicates with DISTINCT DISTINCT shows only unique values. SELECT DISTINCT CardType FROM Sales.CreditCard; ✅ Returns each credit card type only once. Perfect for unique lists. #learnsql

📊 Step 2: Sorting Data (ORDER BY) ORDER BY arranges results in ascending (ASC) or descending (DESC) order. SELECT * FROM Sales.CreditCard ORDER BY CardType; ✅ Lists all cards alphabetically. Use DESC to reverse it 👇 ORDER BY CardType DESC; #LearnSQL @Rita_tyna

🧠 Step 1: Filtering Data (WHERE Clause) WHERE tells SQL which rows to show — just like Excel filters. SELECT * FROM Sales.CreditCard WHERE CardType = 'Vista'; ✅ Shows only Vista credit cards 💳 #LearnSQL #DataSkills @ibn_wittig @OboniiX
