A ADO Recordset Object has an ADO Fields Collection made up of Field objects. Each Field object corresponds to a column in the recordset. You use the ADO Field Object Value Property of Field objects to set or return data for the current record. Depending on the functionality the provider exposes, some collections, methods, or properties of a Field object may not be available.
The collections, methods, and properties of a Field object are used to:
return the name of a field with the ADO Field Object Name Property.
view or change the data in the field with the ADO Field Object Value Property.
return the basic characteristics of a field with the ADO Field Object Type Property, ADO Field Object Precision Property, and ADO Field Object NumericScale Property properties.
return the declared size of a field with the ADO Field Object DefinedSize Property.
return the actual size of the data in a given field with the ADO Field Object ActualSize Property.
determine what types of functionality are supported for a given field with the ADO Field Object Attributes Property and ADO Properties Collection.
manipulate the values of fields containing long binary or long character data with the ADO Field Object AppendChunk Method and ADO Field Object GetChunk Method methods.
resolve discrepancies in field values during batch updating with the ADO Field Object OriginalValue Property and UnderlyingValue properties (if the provider supports batch updates).
 Note
|
All metadata properties (Name, Type, DefinedSize, Precision, and NumericScale) are available before opening the Field object's recordset. Setting them at that time is useful for dynamically constructing forms. |
