Adding Comments to Queries
Comments can span multiple lines but cannot be nested inside one another. Comments are stored in the history database as part of the query.
1 Highlight the code you want to comment out.
2 On the Query Window toolbar, click or press Ctrl+/ to comment out the highlighted text.
Note: If you select a comment, clicking on the icon removes the comment delimiter from around the selected comment, restoring the contents as part of the query.
