🗄️ Standard SQL Query Patterns

Examples below demonstrate common SQL patterns. Table and column names are illustrative; adapt them to the question given.

SELECT + WHERE

SELECT Name, Marks
FROM STUDENT
WHERE Marks > 80;

ORDER BY

SELECT Name, Marks
FROM STUDENT
ORDER BY Marks DESC;

Aggregate + GROUP BY + HAVING

SELECT Stream, COUNT(*)
FROM STUDENT
GROUP BY Stream
HAVING COUNT(*) > 2;

Use the syntax and SQL features prescribed for your CBSE academic session.
