<p>
Comments aren't SQL commands, but can occur in SQL queries. They are treated as
whitespace by the parser. They can begin anywhere whitespace can be found, including
inside expressions that span multiple lines.
</p>
<p>
SQL comments only extend to the end of the current line.</p>
<p>
C comments can span any number of lines. If there is no terminating delimiter, they
extend to the end of the input. This is not treated as an error. A new SQL statement
can begin on a line after a multiline comment ends. C comments can be embedded anywhere
whitespace can occur, including inside expressions, and in the middle of
other SQL
statements. C comments do not nest. SQL comments inside a C comment will be ignored.
