 Formally, this method is also used for statements with multiple results (result sets and update counts), but Firebird only supports at most one result set and at most one update count.

 Firebird returns a 32-bit identifier of the allocated object, a statement handle, that must be used in next operations.
 2. An SQL statement is compiled into an executable form and is associated with the specified statement handle.
