Ever wonder how SQL actually processes your query? Here's the real order:
1๏ธโฃ FROM โ Identifies source tables & joins
2๏ธโฃ WHERE โ Filters rows based on conditions
3๏ธโฃ GROUP BY โ Groups filtered data
4๏ธโฃ HAVING โ Filters groups created
5๏ธโฃ SELECT โ Chooses which columns/data to return
6๏ธโฃ DISTINCT โ Removes duplicates (if used)
7๏ธโฃ ORDER BY โ Sorts the final result
8๏ธโฃ LIMIT/OFFSET โ Restricts number of output rows
๐ฅ Example:
SELECT department, COUNT(*)
FROM employees
WHERE salary > 50000
GROUP BY department
HAVING COUNT(*) > 5
ORDER BY COUNT(*) DESC
LIMIT 10;
๐ก Note: Even though SELECT comes first when we write SQL, it's processed after WHERE, GROUP BY, and HAVINGโknowing this prevents sneaky bugs!
