    Example 2. A statement containing a wildcard parameter

    The % symbol is the escape character in URIs, so when using % as a wildcard in a query, we need to escape that by replacing it with its corresponding ASCII code %25.

    Request
    curl -v http://localhost:8093/query/service \
         -u Administrator:password \
         -d 'statement=SELECT meta().id
                       FROM `travel-sample`.inventory.hotel
                       WHERE meta().id LIKE $pattern
           & $pattern="hotel_1002%25"'
