Field Object

A Field object represents a column of data with a common data type.

Collections

Properties

ActualSize, Attributes, DefinedSize, Name, NumericScale, OriginalValue, Precision, Type, UnderlyingValue, Value

Methods

AppendChunk, GetChunk

Remarks

A Recordset object has a Fields collection made up of Field objects. Each Field object corresponds to a column in the Recordset. You use the 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.

With the collections, methods, and properties of a Field object, you can do the following:

· Return the name of a field with the Name property.

· View or change the data in a Recordset with the Value property.

· Return the basic characteristics of a field with the Type, Precision, and NumericScale properties.

· Return the declared size of a field with the DefinedSize property.

· Return the actual size of the data in a given field with the ActualSize property.

· Determine what types of functionality are supported for a given field with the Attributes property and Properties collection.

· Manipulate the values of fields containing long binary or character data with the AppendChunk and GetChunk methods.

· Resolve discrepancies in field values during batch updating with the OriginalValue and UnderlyingValue properties.

To refer to a Field object in a collection by its ordinal number or by its Name property setting, use any of the following syntax forms:

recordset.Fields.Item(0)
recordset.Fields.Item("name")
recordset.Fields(0)
recordset.Fields("name")
recordset(0)
recordset("name")
recordset![name]
