Specifies COLUMN_ENTRY macros that follow the SET_PARAM_TYPE macro input, output, or input/output.

Syntax

  
SET_PARAM_TYPE(  
type  
 )

Parameters

type
[in] The type to set for the parameter.

Remarks

Providers support only parameter input/output types that are supported by the underlying data source. The type is a combination of one or more DBPARAMIO values (see DBBINDING Structures in the OLE DB Programmer's Reference):

DBPARAMIO_NOTPARAM The accessor has no parameters. Typically, you set eParamIO to this value in row accessors to remind the user that parameters are ignored.
DBPARAMIO_INPUT An input parameter.
DBPARAMIO_OUTPUT An output parameter.
DBPARAMIO_INPUT | DBPARAMIO_OUTPUT The parameter is both an input and an output parameter.
