First approach query : SELECT del_partner, COUNT(CASE WHEN delivery_time > predicted_time THEN 1 ELSE 0 END) AS del_delivery FROM order_details GROUP BY 1; Different syntax, same result. This is the beauty of SQL it’s more about understanding. #sqlQuery

Now you’re just translating your mental blueprint into SQL. Because you planned it in your head, you’re not guessing you’re building 💪 SQL is like solving a puzzle. The clearer you see the picture, the easier it is to fit the pieces together. #SQLQUERY #Datamanipulation

Can’t use: Aggregate functions (SUM, COUNT, AVG, etc.) directly in WHERE. USE WITH: select, Delete, Update. Most importantly it filters rows before grouping. HAVING Purpose: Filters groups after aggregation happens. #DataAnalytics #SQL #SQLQuery
