Data Type Conversions Supported by MSDADC.DLL
The Data Conversion Library supports a limited set of conversions. The DBTYPE_BYREF modifier is only supported on the destination type for variable length data types (DBTYPE_BYTES, DBTYPE_STR, DBTYPE_VARNUMERIC, and DBTYPE_WSTR).
In the conversion tables, an X indicates that the conversion is supported by MSDADC.DLL. All data types can be converted to the same data type.
Note Supported data conversions can be determined through the IConvertType interface.
