问题
I am trying to programmatically create an SSIS package containing a simple data flow from table A to table B in the same database. I am using the example given here. The package gets created and saved to a dtsx file, but when I open it in visual studio I see that the source and destination tables have not been selected.
I also want to insert a transformation task in between before it reaches the destination.
EDIT
Well I have managed to get the source and destination tables selected and the task even ran successfully. Turns out I needed to
(a) use one oleDB connection each for the source and destination [I don't like this way; I want to use one connection only]
(b) set the Accessmode to 3 in the destination SetComponentProperty("AccessMode", 3) which equates to Table or View - fast load.
Is there some documentation on this somewhere. All I can find is what SetComponentProperty does, and not what all parameters it can take to do that. eg. what else can I put there besides "AccessMode"?, what does the second parameter 3 or 2 or 1 stand for?
Still trying to map the monikers. STOCK:PipelineTask means DataFlow Task. What is the moniker for say... copy column?
回答1:
Yes, this is one of my frustrations with SSIS: that they do not provide simple table or map of the new terminology.
You can use a small piece of code to discover components available for use.
The code is located here: http://msdn.microsoft.com/en-us/library/ms136106.aspx
When I ran it, I found the moniker for copy column to be: Name: Copy Column CreationName: DTSTransform.CopyMap.1

If you don't want to use the DTS .net assemblies you can use EzApi which provides a simpler syntax to create SSIS package programmatically.
EzAPI is a .NET library written in C# by Evgeny Koblov one of the testers on the SSIS team to abstracts away a lot of the cumbersome low-level coding needed to create SSIS packages XML directly in a programming language
EzApi was first published as a part of the SSIS community samples project created by Microsoft product team:
- SQLSrvIntegrationSrv
- GitHub - MSSQL SSIS community samples
And later it is published as a separate project to add support SQL Server 2016:
- GitHub - EzApi2016
- NuGet Gallery - EzApi
To get starteed with EzApi there are many link on the internet that you can refer to such as:
- EzAPI – Alternative package creation API
- EzAPI Overview
- EzApi a C# library for creating SSIS packages programatically
- Getting Started with EzAPI

I used to have a copy of SQL Server 2005 Integration Services, a Wrox book. I am pretty sure it has a whole chapter or two dedicated to programmatically working with SSIS packages. You may want to check out a local book store and flip through it, it may have what you want.
Sorry I can't give you anything more specific than a book reference. Good luck.
