Comments in SQL query have a simple purpose. They keep the code well-arranged for others and also explain its logic. If you mark some text as a comment it will not be taken as an SQL command and therefore it will not be executed. SQL Comment can be written down in two ways:
- Comment can be marked by double dash “–“. This solution is valid for 1 line only.
- Comment can be marked by “/**/” at the start and at the end
Comment in SQL is distinguished by green color.
SQL Comment Syntaxe
First way of making a comment in SQL:
-- Comment 1 -- Comment 2
Second way of making a comment in SQL:
/* Comment 1 Comment 2 */
Second way of commenting is preferable when the comment takes up more than 1 row.
