how to mass comment in pgadmin sql

I’m currently working on a project using pgAdmin, and I’ve run into a bit of a roadblock that I hope someone can help me with. I have a sizable database with numerous tables, and I want to add comments to many of them for better documentation and understanding of the schema. However, doing this manually—one table at a time—seems incredibly tedious and time-consuming, especially since I have about 50 tables to document.

I’ve heard that there might be a way to mass comment on multiple tables at once using SQL, but I’m not quite sure how to go about it. My goal is to add descriptions that will help future developers (or even myself down the line) understand the purpose and structure of each table without requiring them to dive deep into the code right away. Is there a straightforward SQL command or a script that I can use in pgAdmin to achieve this? Any examples or tips would be greatly appreciated, as I want to ensure that my database is well-documented without having to manually comment on each table individually. Thank you in advance for your help!

    1. How to Mass Comment in pgAdmin SQL

      So, like, if you wanna comment a bunch of lines in your SQL code in pgAdmin, you can do it kinda easily. You know how you have this awesome SQL editor where you write all your queries? Yeah, you can select the lines you want to comment.

      Once you’ve highlighted the lines, just hit Ctrl + / on your keyboard. That’s it! It’s like magic—poof! The lines turn into comments. Super simple, right?

      But wait! What if you wanna uncomment that same code later? Just select the commented lines and hit Ctrl + / again. It’s like toggle commenting! Pretty neat!

      Just make sure you’re in the query editor thingy because it won’t work if you’re just clicking around somewhere else. And, oh, if you mess anything up, don’t freak out—there’s always the undo button! Happy coding!


    2. To effectively implement mass comments in pgAdmin using SQL, you can utilize the built-in SQL comment syntax that PostgreSQL supports. This allows you to add comments to your SQL scripts to document your code comprehensively. For single-line comments, use two hyphens (`–`) before the text you want to comment out. For multi-line comments, enclose your comments with `/*` at the beginning and `*/` at the end. For instance, if you are documenting a SQL function or a complex query, you could structure it like this:

      “`sql
      /* This is a multi-line comment
      detailing the purpose and usage
      of the following SQL statement */
      SELECT *
      FROM my_table; — This retrieves all records from my_table
      “`

      If you’re looking to comment out multiple lines of SQL code, you might wrap your entire section in a multi-line comment block. It is also prudent to use comments judiciously to ensure that your code remains readable without becoming cluttered. When automating or writing scripts for mass comments, consider employing a text editor or IDE that supports regex find-and-replace functionality for comment formatting, which could streamline your workflow significantly. Moreover, when executing large scripts through pgAdmin, remember to maintain a clean separation of concerns by commenting each block logically, enhancing the maintainability of your database scripts over time.
