SQL DISTINCT vs GROUP BY — You're Using the Wrong One #shorts #sql

SQL DISTINCT vs GROUP BY — why most analysts reach for DISTINCT by default and end up giving their manager an incomplete answer without realising it.
DISTINCT removes duplicate rows. That is it. That is the entire job of DISTINCT. If you want to count, filter, or analyse data by group — DISTINCT cannot do that. GROUP BY can. Here is the clearest example. Your manager asks how many orders each customer has placed. You write DISTINCT on customer ID and get back a clean list of unique customers. That is not the answer. That is half the answer. GROUP BY customer, then COUNT orders — that gives you the number your manager actually wanted. DISTINCT tells you who exists. GROUP BY tells you what they did. Most analysts use DISTINCT because it feels simpler and the query runs without errors. But a query that runs without errors and answers the wrong question is worse than a query that breaks — because nobody flags it until the numbers stop making sense in a meeting. Every SQL interview tests this difference specifically because it reveals whether a candidate understands what their query is actually doing or just whether it executes. Know it cold before your next round.
