Add Comments to Your SQL Statements

Adding comments to SQL statements helps make the SQL queries more readable. Comments aren’t executed as part of the SQL query.

To comment out a single line, or part of a line, use -- at the beginning of a line or in the middle of a line.

For example, these two lines are comments.

To add a multiline comment, enclose the block between /* and */ characters.

For example, this entire block is commented out.
