Day 10 of the @hertechtrail #HTTDataChallenge was to retrieve customer names in alphabetical order using SQL query. SELECT name (retrieves only the name column) FROM accounts (your customer names are in the accounts table) ORDER BY & ASC (sorts in ascending order ) #SQLQuery

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
