CtDescribedOLEDBProvider (Property)
In french: CxProviderOLEDBDécrit
OLE DBAvailable only with this kind of connection
The CtDescribedOLEDBProvider property is used to get and set the name of the OLE DB provider (also called OLE DB server). You can:
  • Find out the name of the OLE DB provider used for the connection to a table by OLE DB. This provider was defined in the data model editor or when the data file was described through programming.
    Caution: The CtDescribedOLEDBProvider property ignores any changes made with HConnect.
    This property can be used for a data file defined in the data model editor or programmatically.
  • Define the name of the OLE DB provider used for the connection to a table by OLE DB (when the data file was described through programming). This property is equivalent to the CtOLEDBProvider property.
Reminder: HConnect is used to redefine one or more parameters of the OLE DB connection to a table. By default, the characteristics of the OLE DB connection are defined:
  • in the data model editor when describing the data file,
  • when the data file is described through programming.
Example
// Define the name of the OLE DB provider
Customer.CtDescribedOLEDBProvider = hOledbOracle
...
// Validate the data file description
HDescribeFile(Customer)
