OdaDataSetParameterHandle
Represents the parameter for data set drivers. The parameter is the part of
the data set definition, if defined. A parameter can be an input or output
parameter. A parameter can also be input and output parameter. Each data set
parameter has the following properties:
- Name
- a data set parameter has a required name.
- Position
- a data set parameter has an optional position for it.
- Data Type
- a data set parameter has a choice data type: any, integer, string, data time, decimal, float, structure or table.
- Is optional
- whether this parameter is optional.
- Is Nullable
- whether the value of this parameter can be nullable.
- Is Input
- whether this parameter is an input parameter.
- Is Output
- whether this parameter is an output parameter.
