How to Comment Multiple Lines in a Databricks Notebook

Here’s how to comment out multiple lines in a Databricks notebook, depending on the type of code:

Python or Scala Code

1. Highlight the lines you want to comment.
2. Use these shortcuts:
   • Windows/Linux: Press Ctrl + /
   • Mac: Press Cmd + /

   This adds a # at the start of each selected line.

SQL Code

• Use bracketed comments to comment out multiple lines:
  • Start with /* and end with */.
  • Example:

    sql

    Copy code

    /*
SELECT * FROM database.tablename


    WHERE condition
*/

  • This temporarily disables the code without deleting it.

Uncommenting

• To uncomment, select the commented lines and press Ctrl + U (or Cmd + U on Mac).
