DTS Custom Transformation Fundamentals
SQL Server 2000
The following topics describe functions, interfaces, data structures and registration issues you must consider when you implement Data Transformation Services (DTS) custom transformations.
|COM DLL Infrastructure||Describes the functions involved with creating, loading and registering the component that all COM DLLs must implement.|
|IDTSDataPumpTransform Interface||Describes the interface that all custom transformations must implement. IDTSDataPumpTransform supports initialization, schema validation, data transformation and termination.|
|IDTSDataPumpTransform2 Interface||Describes the interface that custom transformations used with Microsoft® SQL Server™ 2000 must implement. IDTSDataPumpTransform2 supports pre-validation and multiple phases of data transformation.|
|Column Information Structures in DTS Transformations||Describes the data structures that contain information about the source and destination columns. These data structures are arguments to the methods of IDTSDataPumpTransform and IDTSDataPumpTransform2.|
|Registration Requirements for Transformations||Describes the information that must be stored in the system registry that allows DTS to find and run the transformation.|
