how can i add comments in mysql

Question

I want to add comment in SQL code. How can I do this? I'm using MySQL.

Answer 1

To add comments in SQL code when using MySQL, you can follow these steps:

Use the double-dash (--) notation: Simply insert two dashes (--) at the beginning of the line where you want to add the comment. Everything after the dashes will be considered a comment.

Use the hash symbol (#): You can also use the hash symbol (#) to begin a comment. Similar to the double-dash notation, anything after the hash symbol will be treated as a comment.

Use the /* ... / notation: If you have multi-line comments, you can enclose them between / and */. This notation allows you to add comments that span multiple lines.
 

-- This is a single-line comment

# This is also a single-line comment

/* This is a

   multi-line comment */

These methods will help you add comments to your SQL code in MySQL, making it easier for you and other developers to understand and maintain the code in the future.

Answer 2

Comments really help programmers as well as others to easily understand what the code is all about, so MySQL also provides a format to add comments to increase the readability of the program.

Have a look at a different format to add a comment :

• # adding comment

• --adding a comment

• /* adding comment*/

Answer 3

To add comments in MySQL SQL code, you can either use the double-dash notation (--) or the hash symbol (#) for single-line comments. Simply insert either of these symbols at the beginning of the line where you want to add the comment. For multi-line comments, you can enclose them between /* and */. These comment notations will help you document your code and provide explanations or clarifications for yourself and other developers working with the code.

Answer 4

Use "--" or "#" for single-line comments, and "/* ... */" for multi-line comments in MySQL SQL code.
