Comment on Generating Surrogate Keys by Bob

I have the same problem as AS. In SSIS 2008, I can’t get the key from the script into the OLE DB Destination task. When I put a dataviewer between the Script Transformation task and the OLE DB Destination task, it doesn’t show anything.

Thanks,
Bob

Comment on SSIS 2012 – SSIS Environment Variables String Limit by Nigel

My apologies, I’m confusing this limitation with that of the limitation on holding nvarchar(max) parameters in strings data type variables. This is where the System.Object data type approach is required. My apologies. You are right that the expression limitation has been removed (thank goodness). Is it possible to define an environment variable as type System.Object as a possible workaround?

The 4,000 character expression limit has been removed in 2012. So you should be able to build your dynamic SQL no problem.

This has been an issue for some time. MS have been aware of this and there is even a Connect issue where they have closed giving the stock “By Design” reason.

http://connect.microsoft.com/SQLServer/feedback/details/260730/ssis-maximum-string-length-of-4000-is-too-restrictive

I do find the “By Design” reason somewhat worrying, in that they are ignoring a request to change the design of something that has been highlighted as not fit for purpose with an answer of essentially “It’s been designed like that and we aren’t going to change it so live with it”. Two years to get around to making such a fundamental change that will add considerable flexibility to a developer’s toolset (dynamic sql construction being just one example of where this can really help) is really rather rubbish.

For those trying to use a nvarchar(max) datatype somewhere, it is possible to use the System.Object variable data type in SSIS 2008 to get around this limitation. Not particularly obvious if you are not coming from a DotNet programming background.

Comment on SSIS – What does the SSIS Service actually do, anyway? by Simon Hardman

Regarding piers7’s question I was wondering about this too. If you are using the /DTS option (or Package Source = SSIS Package Store in the Agent Job UI) then the SSIS service must be running. If you are using /SQL (Package Source = SQL Server) then the SSIS service doesn’t need to be running.

Comment on SSIS – Task and Component Naming Conventions by Emil Glownia

Emil Glownia — Tue, 27 Dec 2011 11:17:43 +0000

Thanks I was looking for that. Prefixes for me is a must… I might know what the package does but names are ambiguous and with prefixes I straight away narrow it down to specific task type which saves me time + saves a lot of time for those who haven’t developed the package.

Regarding the comparison to diagram and circle I think it is missed comparison. Logging is a table (something you don’t visualize) and not a diagram therefore you will never see a circle unless you put prefix that will indicate it relates to “mathematical circles” and not “cultural circles”.
