Extending SSIS with Custom Tasks Darren Green Konesans Ltd
Agenda Extending SSIS Types Six Steps Tasks Debugging Installation When and Why?
Types Task Pipeline Component Source Destination Transform Log Provider For Each Enumerator Connection Manager Connection Manager
Six Steps Create project Add references Add signing key Write code Compile Install
References Microsoft.SQLServer.ManagedDTS Microsoft.SqlServer.Dts.Runtime Microsoft.SQLServer.DTSRuntimeWrap Microsoft.SqlServer.Dts.Runtime.Wrapper Microsoft.SqlServer.PipelineHost Microsoft.SqlServer.Dts.Pipeline Microsoft.SqlServer.DTSPipelineWrap Microsoft.SqlServer.Dts.Pipeline.Wrapper Microsoft.SqlServer.Dts.Design Microsoft.SqlServer.Dts.Runtime.Design
Custom Objects - Template [ObjectAttribute(Information)] public class MyCustomObject : BaseClass { public override void BaseMethod() { // Custom code } }
Classes & Attributes Base Class Base Class Attribute Attribute ConnectionManagerBase DtsConnectionAttribute PipelineComponent DtsPipelineComponentAttribute ForEachEnumerator DtsForEachEnumeratorAttribute LogProviderBase DtsLogProviderAttribute Task DtsTaskAttribute
Demo Simple Task
Tasks Methods InitializeTask Validate Execute Properties Use attributes, editors and type converters Use connection GUID Write only for security when required Custom persistence for sensitive data or complex types
More Task Features Custom Events Custom Log Entries Breakpoints (IDTSBreakpointSite)
Create a Task User Interface Create UI class (Implement IDtsTaskUI) Create UI form Set task s UITypeName attribute
Demo Simple Task User Interface
Advanced Task User Interfaces Microsoft.DataTransformationServices.Controls Microsoft.DataTransformationServices.Controls.dll DTSBaseTaskUI Base Form Class DTSTaskUIHost Control, paged control Class per page, implement IDTSTaskUIView
UI Classes & Attributes Interface / Class Interface / Class Notes Notes IDtsConnectionManagerUI IDtsConnectionManagerUI Use Win Form Use Win Form CManagedComponentWrapper IDtsComponentUI ForEachEnumeratorUI UserControl IDtsLogProviderUI Not Supported Use Win Form IDtsTaskUI
Debugging Designer Design time Attach to devenv.exe Designer Runtime Attach to DTSDebugHost.exe Component Project Runtime Start external program C:\Program...\DTExec.exe /F "C:\...TestPackage.dtsx
Debugging Tips Ensure class and strong name is fixed at start Must restart BIDS between builds, slow! Use DTExec for all runtime Use Post Build Event for install copy "$(TargetPath) C:\Program... gacutil.exe" /if "$(TargetPath) Ensure persistence complete
Installation Locations Designer Enumeration Folder Designer location only (x86 Only) C:\Program Files\Microsoft SQL Server\90\DTS\<Object> \Connections \ForEachEnumerators \Tasks \LogProviders \PipelineComponents Global Assembly Cache Runtime loading by execution host
Install Platform Target 32-bit (x86) Location Location x86 x86 x64 x64 IA64 IA64 MSIL MSIL Program Files Design Design GAC Run Run Install in Program Files for Designer Install in GAC for run-time Support for x86 specific targeted assemblies Support for Any CPU / MSIL
Install Platform Target 64-bit (x64) Location Location x86 x86 x64 x64 IA64 IA64 MSIL MSIL Program Files (x86) Design Design GAC Run Run Run Support for x86 only targeted assemblies Support for x64 only targeted assemblies Support for Any CPU / MSIL Designer is x86/MSIL only Can side by side target assemblies
Install Platform Target Itanium (IA64) Location Location x86 x86 x64 x64 IA64 IA64 MSIL MSIL GAC Run Run Support for IA64 Support for Any CPU / MSIL No designer support
64-bit Tools Only Location Location x86 x86 x64 x64 IA64 IA64 MSIL MSIL Program Files (x86) GAC Run Run No x86 file requirement No x86 DTSPath registry key MSI registry search is 32-bit No key, no tools, no designer, no file required!
Install Tips Use MSI builder of choice, e.g. VS, WiX Registry Search for DTS folder location HKLM\SOFTWARE\Microsoft\MSDTS\Setup\DTSPath C:\Program Files\Microsoft SQL Server\90\DTS\ Allow tools only installs, don t require 32-bit key User Interfaces & Support Assemblies? GAC Only Support Files? Use special folders, CommonApplicationData Minimal UI, no options required
When to extend Reuse in multiple packages Increased Development vs Lower Maintenance Access legacy resources (COM) Complex business logic More advanced code requirements Powerful IDE Language choice
