IDTSExternalMetadataColumn100 Interface

Represents a column from an external data source.

Namespace:  Microsoft.SqlServer.Dts.Pipeline.Wrapper
Assembly:  Microsoft.SqlServer.DTSPipelineWrap (in Microsoft.SqlServer.DTSPipelineWrap.dll)

public interface IDTSExternalMetadataColumn100 extends IDTSObject100

The IDTSExternalMetadataColumn100 type exposes the following members.

Public propertyCodePageGets or sets the character set used to interpret the data contained in the column.
Public propertyCustomPropertyCollectionGets the custom property collection of the external metadata column.
Public propertyDataTypeGets or sets the DataType of the column.
Public propertyDescriptionGets or sets the descriptive text for the IDTSExternalMetadataColumn100 object.
Public propertyIDGets or sets the ID of the IDTSExternalMetadataColumn100.
Public propertyIdentificationStringGets the String that uniquely identifies the IDTSExternalMetadataColumn100 object in the data flow.
Public propertyLengthGets or sets the length of the external metadata column.
Public propertyMappedColumnIDGets or sets the ID of a column that is mapped to the IDTSExternalMetadataColumn100 object.
Public propertyNameGets or sets a String that contains the name of the IDTSExternalMetadataColumn100.
Public propertyObjectTypeReturns the value from the DTSObjectType enumeration that corresponds to an external metadata column.
Public propertyPrecisionGets or sets the number of decimal places stored by an external metadata column that has a decimal data type.
Public propertyScaleGets or sets the number of digits stored by an external metadata column that has a decimal data type.

The IDTSExternalMetadataColumn100 column represents a column in a remote data source. It contains the same properties as the external data column. This allows components to validate the columns in their IDTSInput100 and IDTSOutput100 column collections when the external data source itself is unavailable, or when a round trip to the external source is undesirable.
