Constructs an identifier with a single qualifier.
constexpr identifier( string_view qualifier, string_view id);
Identifiers with one qualifier are used for field, table and view names.
The qualifier identifies the parent object. For instance, identifier("table_name",
"field_name")
maps to:
"`table_name`.`field_name`"
