SQL comments are very useful to explain the meaning of the query. It's currently impossible to put it at the beginning of the field as seen on the screen capture: it leads to an error: Statement must be a SELECT.

It would be great to make it possible because:

• as the request is the title of the page:
  • it eases the search with search engines
  • it eases the search in the browsers' url field
• it acts as a kind of title: the global meaning of the query is immediately understandable
• some tools, such as Slack, are shortening long URLs and displaying the beginning of the URLs (eg. https://example.org/products?sql=select+%28length%28data_quality_errors_ta[...]+%21%3D+%22%22+group+by+NB_of_issues+order+by+NB_of_issues+desc+limit+200)

Beginning a query with a comment is possible with SQLite.
