Writing Better MySQL Code: Why Comments Are More Powerful Than You Think

If you work with MySQL regularly, you already know that queries can get messy fast — especially when working with complex joins, nested subqueries, or dynamic logic.

But there’s one underrated tool that can bring structure, clarity, and collaboration to your database scripts: comments.

They don’t affect execution. They don’t show up in results. But well-placed comments can turn confusing scripts into clean, readable code that your future self — or your teammates — will thank you for.

Why Comments Matter in MySQL

Here’s why you should take comments seriously when writing MySQL code:

• Comments help you go beyond what the query does — they explain why.

• Clear annotations reduce onboarding time for new developers or DBAs.

• Temporarily disabling lines with comments helps you experiment without deleting code.

• Six months from now, a comment might be the only clue to understanding a query you wrote today.

• Comments can act as markers or separators when generating queries programmatically.

How Comments Work in MySQL

MySQL supports:

• Single-line comments

• Multi-line comments

• Inline comments inside queries

• Version-specific comments (useful for cross-version compatibility)

Each type has its own use case, and knowing when to use which makes your scripts not only cleaner but also more portable and reliable.
