Name

OpenXPKI::Server::Database::Role::CountEmulation - Moose role for database drivers to emulate row count with a subselect

Description

This is the default implementation to count the number of rows in a select by using "SELECT COUNT(*) ... from (...) as tmp"

It might be overriden if the specific RDBMS requires a different syntax (e.g. Oracle) or there is a builtin method.
