DISTINCT Clause
DISTINCT
In MySQL, the DISTINCT keyword is used in the SELECT statement to eliminate duplicate rows from the result set. It is commonly used when you want to retrieve unique values from a specific column or a combination of columns in a table.
Syntax
The syntax for the DISTINCT clause is as follows:
SELECT DISTINCT column1, column2 FROM table_name WHERE condition;
Example
Suppose we have a Products table as shown below:
and we want to retrieve the distinct categories:
SELECT DISTINCT category FROM Products;
java
SELECT DISTINCT category
FROM Products;The result of this query would be a table showing the following rows:

🎨 Explain it visually
Build the mental picture, not memorization.
I just read a lesson on **DISTINCT Clause** (Databases) and want to truly understand it. Explain DISTINCT Clause from first principles using ONE vivid real-world analogy and a visual mental model — draw it as ASCII art or a clear step-by-step diagram — with a concrete example using real numbers. Then ask me one question to check I got the mental picture, and wait for my reply. If you're unsure or a claim isn't standard, say so and reason from first principles instead of guessing.
🤔 Walk me through it (interactive)
Socratic — adapts to where you're stuck.
Teach me **DISTINCT Clause** interactively. Ask me ONE guiding question at a time, wait for my answer, and adapt to my confusion — build the idea with me step by step instead of explaining it all at once. If you're unsure or a claim isn't standard, say so and reason from first principles instead of guessing.
🧪 Quiz me & fix my gaps
Active recall exposes what you missed.
Quiz me on **DISTINCT Clause** with 5 questions, easy to tricky, ONE at a time. Tell me if each answer is right; at the end, explain clearly what I got wrong and why. If you're unsure or a claim isn't standard, say so and reason from first principles instead of guessing.
