Comments can be used to annotate, describe and explain your PQL queries. They do not affect the actual query execution.

All characters inside a comment will not be interpreted as part of the PQL query. In PQL, there are two types of comments: line comments and block comments.

Line comment

A line comment starts with double dashes (--). All characters between the start of the comment and the end of the line are part of the comment.

Block comment

A block comment starts with a slash and an asterisk (/*), and it ends with an asterisk and a slash (*/). All characters in between are part of the comment. The comment can span multiple lines.
