  The SQL module supports string expansion.  The input strings are just
SQL statements.  The output is just a one-line string containing the
result of the SQL query.

  This means you can call SQL procedures directly from unlang:

	if ("%{sql: call procedure with args}" > 2) {
		... more than 2 people logged in ..

  Very simple!
