Which Clause is Similar to Having

Which Clause is Similar to Having is a MySQL topic you learn with one small college example — a students table with roll, name, marks. Say what Which Clause is Similar to Having does in one sentence, then write the shortest SQL that shows it.

Pattern: USE college; then a CREATE/SELECT/UPDATE that needs Which Clause is Similar to Having. If it is a function, SELECT it on one column. If it is DDL, run SHOW / DESCRIBE after so you can see the change.

Trap: only reciting the heading Which Clause is Similar to Having with no SQL. Interviewers ask you to type. Another trap: mixing this up with a neighbouring command (DELETE vs TRUNCATE vs DROP, WHERE vs HAVING, JOIN vs UNION).

Keep the example on paper — two or three rows. Change one value. Predict the result before you run it.

Exam tip

What is Which Clause is Similar to Having? One sentence + one tiny SQL on students.

Which Clause is Similar to Having — sample query

CREATE TABLE sales (id INTEGER PRIMARY KEY, region TEXT, amount INTEGER);
INSERT INTO sales VALUES (1, 'N', 100), (2, 'N', 80), (3, 'S', 120);
SELECT region, SUM(amount) AS total
FROM sales
GROUP BY region
HAVING total >= 150
ORDER BY total DESC;
