The PmaAdo object directly enables the objects and methods of the ADO technology. Especially the AdoRecordset object as a result of the SQL statement SELECT. This technology ensures that the system is as open as possible and averything that can be done using the ADO technology, can also be used in the PROMOTIC system.
This object can be created in objects: PmaRoot, PmaFolder, PmaPrototype. Multiple objects of this type can be created in such objects.
The usage of the PmaAdo object requires purchase of the "PmDB" licence. With the freeware version PmFree, or when developing the application (with development environment for tersting purposes), this component is always functional.
