Supported Data Types
The following table contains the valid data types supported by the OLE DB Provider for Commerce Server. The Support column specifies whether the data type is supported by the Data Warehouse, the Profiling System, or both. Binary data is not supported by the Data Warehouse, but is supported by the Profiling System in the following contexts:
- Access by means of a ProfileService object or a Recordset object.
- Modification by means of a ProfileService object or a Record object.
