ADO » Parameter » Type
- Syntax:
- DataTypeEnum = parameterobject.Type
Sets or returns a DataTypeEnum value that specifies the data type.
The Type property sets or returns a DataTypeEnum value which is the data type or
operational type of the Parameter object.
This property is read/write.
Unfortunately, some providers may not support all of the possible data types.
If a provider encounters a data type that it does not recognize, it will usually change it to
a data type that it does recognize.
