VS SSRS Project Gotchas

I now present to you, a recent adventure in building & configuring a SSRS 2016 / VS2015 project to replace our aging SSRS 2008R2 / VS2008 setup.  In trying to make things ‘better’, I wanted to centralize the storage of the Data Sources.  I found a tip on StackOverflow with a neat (albeit hacky) idea on how to do this.  So I started diving into it.  Here’s how that went.

The Setup

I have a bunch of published reports on a ‘real’ report server (SSRS instance), which were created off-the-cuff using Report Builder 3.0 (no source-control connection or anything).  So the first thing I had to do was go and download each RDL (thanks, Microsoft… ugh!), to my local VS2015 project folder, so I could bring them into my SSRS project.  I didn’t bother trying to download/copy the Data Sources (they’re basically just connection-strings, and anyway you can’t download them from Report Manager), so I settled for re-creating those in VS.

Then it was time to set up the solution & projects.  I prefer to organize my reports in context-relevant folders, like “Operations”, “Marketing”, etc.  In order to do this sensibly, within the VS solution, you need to create a Project for each major fold you’ll have.  Makes sense; this is how the old solution was constructed too.  Here’s where I tried to improve things:  I created a “Datasources” project, which would house just the shared Data Sources.  Here’s where I created my new data-sources, setting them up with saved SQL auth (login & pwd).  Sure, maybe not the “best practice” but it keeps things simple — my SSRS user only ever has read-only db access, and the pwd is managed well enough to keep auditors happy.

Thus, my plan (in following the SO tip) was to have all the other projects’ Data Sources be pointers to these shared Data Source files (RDS​’s).  Sounds good in theory, right?

what could possibly go wrong
ooh, sparkly!

Starting to Implement

Well.  I started small with just one project, one report, and one data source.  I went into my Nate test project, did “add existing item” into the Reports folder, and browsed to pick the rdl that I had just downloaded from my live SSRS server.  I then went to my Datasources project, copied the rds that I needed, pasted it into Nate test project’s Shared Data Sources folder.

Now at this point there are 2 copies of this file in my solution folder.  We don’t want that.  So I opened up trusty ol’ Notepad++ on the Nate test.rptproj file, and edited the XML node under <DataSources><ProjectItem><Name>My-Source.rds</Name><FullPath>My-Source.rds</FullPath></ProjectItem></DataSources> , changing the FullPath node value to <FullPath>..\Datasources\My-Source.rds</FullPath>.  I then deleted the physical copy of the file at \MySolution\Nate test\My-Source.rds , so that only the shared one physically remains in the filesystem (\MySolution\Datasources\My-Source.rds).

Another way to accomplish this, you may read, is to right-click Shared Data Sources within your project, e.g. Nate test, and say “Add existing item..”, and go select the global shared RDL from your master Datasources project-folder.  However, this still results in a physical copy of the file within Nate test folder!  So in either case you’ll end up doing some editing & deletion.

With me so far?  Okay, here’s where it gets interesting.  I could successfully build and deploy this report to my SSRS server, verifying that it showed my “new thing” (I added a text-box that simply said “This is the new hotness!”).  But I could not preview the report in VS!  Sad panda.  And of course, the most vague generic error message in the world:

An error occurred during local report processing
An error occurred during report processing

How specific and informative!

More Googling led to a somewhat random tip in the vein of “Go to the report properties, Open the report’s Data Source, and re-select the Shared Data Source from the dropdown”.  Combine with “Edit the Shared Data Source, ensure your saved login/pwd is filled in, and Save it”.  Presto!  Previewing now worked.

But why is this?  Well, as it turns out, it’s not all that surprising.  The RDLs are stored without the saved login/pwd, because of course they’re just plain-text XML files.  So to “protect you”, MSFT doesn’t store your SQL auth credentials, even if (and now matter how many times) you click “Save my password” on the connection-properties window (connection-string builder).

Great.  Well, I did that once, for Nate test project.  Let’s see what happens with another project (aka report folder), say Test again.  So I add an existing RDL, I copy-paste the Data Source from the global shared Datasources project, manually edit the rptproj in Notepad++, delete the copied rdl, etc.  I then try to preview the report… and behold, the same maddeningly vague error message!

“Well duh!” you may think to yourself, “the credentials still aren’t stored anywhere un-encrypted!”.  Yes, dear read, you are correct.  But do I want to right-click on this project’s Data Sources, edit it, fill in the credentials, save, rinse, repeat, for every single project?!  A resounding NO!


So what should I do?  I could go type in the credentials to the actual connection-strings contained within the ‘master’ rds files.  Of course then they’re in plain-text for all to see… but wait, do I care?  Another no.  Let’s go edit some connection-strings!

As a reminder, here’s what they will look like:

<ConnectString>Data Source=MyServer;Initial Catalog=MyReportDB;User ID=MyReportUser;Password=ThisIs@nAw3s0meP@ssw0rd!;</ConnectString>

Why did MSFT choose to name the XML node ConnectString in their rds schema instead of ConnectionString?  Don’t ask me!

The Gotchas

Here’s the first gotcha:  My reports (RDLs) need to be re-pointed at the correct Shared Datasource, because currently, as they were downloaded from my ‘real’ SSRS server — which had my desired top-level folder layout of “Datasources”, “Nate test”, “Marketing”, etc. — their Data Sources xml node points at \Datasources\MyDatasource.rdl.  This was the correct path on the SSRS server and still will be the correct path when all is said & done.  BUT, to support local debugging/previewing, the build output has to make a copy of the rds in the Project’s bin\Debug folder, which it will happily do, and then just as happily proclaim Could not find a part of the path 'C:\Users\Nate\Documents\Visual Studio 2015\Projects\MyReportSolution\Nate test\bin\Debug\Datasources\MyDatasource.rdl'. — because DUH, the build system didn’t make you a ‘Datasources’ sub-folder under the Debug folder, why would it!?  So by either manually editing the rdl file to remove the ​​\Datasources\ path from the node, or by clicking on the Report’s Data Sources node in the Report Data pane and re-pointing it at the local Shard Data Source (which again, is itself a pointer to the globally shared Datasources!), you can fix this issue.

In the rdl XML, that looks like this (using strikethru to show what you remove):

<DataSource Name=”MyReport_DataSource”>

And there’s another gotcha:  After we do all this, if we open the rds from within VS solution-explorer, it still won’t “think” it saved the authentication!  But the connection-string will be clearly visible with the plain password.  Here’s a couple pictures of what that looks like.

Data Source properties
Connection properties of the Data Source

Oh, by the way, did I mention how many times VS crashed on me while doing these gymnastics?  At least a few.

Lessons Learned

So, what have we learned?  Well, for one, this is a crappy situation born of poor in-product support.  I should be able to configure Solution-level shared Data Sources, use them in as many Projects (within said Solution) as I want, and have VS configuration management support them; bonus points for doing so with saved & encrypted credentials.  Ideally, when we check this into source-control, we’d check in the “DEV” environment flavor connection-configs.  Then, when the reports get deployed to the “PROD” SSRS server, the same globally shared Data Sources are already present (and they don’t get over-written, thankfully by default!), configured by the DBA with prod credentials, and nobody in the development pipeline needs to know said credentials.  Yay?

But alas.  We live in an imperfect world.  I also live in a world where I’m both the Report Developer, the Report Manager, and the Production DBA.  So guess what I get to do?  That’s right, not care about the connection-string security!

Okay, yes, I care a little.  Depending on my mood.  But not enough to turn my whole dang world upside-down trying to design and implement a robust multi-tiered-environment solution for one measly SSRS repository.  Kudos to you if you do — you’re a better man than I.

Or “better woman”.  But I’m not a woman.  So I guess the correct phrasing would be “You’re a better woman than I am a man.”  No, that’s not right.  “You’re a better person than I am?”  Sure, I guess that works.

In Review

To recap:

  1. Create the solution & projects
  2. Create the global shared Datasources project, and create your Data Sources (RDS‘s)
  3. Import your Reports (RDL‘s) to each requisite report-project
  4. Manually edit your rptproj to point the data-sources at the central shared path
  5. Manually edit your RDL‘s to remove previously established paths to the data-sources
  6. Configure your rptproj‘s to output to the correct folders on the report server — this should be done by default, i.e. VS has the “intelligence” to guess these for you, but just double-check.
  7. Build, Preview, and Deploy!
  8. Commit it all to source-control and let the collaboration begin.

And now to go automate all this with PowerShell… right after this beer.

Anyway.  Until next time, folks!  If I’ve made any mistakes, missteps, or otherwise offending your technical sensibilities, and/or if you know of a better way to accomplish what I’m after, I’d love to hear from you in the comments!  =)


Hacking DLM Dashboard, Part 2

Another teaser, just to keep you waiting… I promise I’ll finish it soon!

This hack is about change buildup/bloat.  When you ignore a particular DB’s schema drifts for a while, the amount of changes that the “Review” page needs to show gets larger and larger.  Until, eventually, there’s simply too much content for it to handle, and it dies.  This is a bummer, because you want to ack those changes, but you don’t necessarily need to see them all in detail, as long as you have a general idea of what they were about.

So, this will be a tale of how I purged a set of un-acknowledged changes from DLM Dashboard for a specific Server/Database.  RG support, bless their heart, wanted me to go to the document repo (which, if you’re not aware, uses a RavenDB back-end stored on your local file system) and purge everything.  But I said no, I think we can do better than that.

Plus, if you really really care about those changes, you can use the RavenDB Studio (GUI) to dump the documents to CSV — i.e. if this tool is part of your audit/compliance toolbox and you don’t want to lose those changes, but you need to be able to “move on with life” by acking the changes to the DB so that you can resume checking it on a regular basis without having a page-hang/crash.

This will be screenshot-heavy, censorship-heavy (to avoid divulging company secrets!), and meme-free (I know, I know, some of you will thank me and others will be a sad panda).

More to come, stay tuned!

Hacking RedGate DLM Dashboard

This is a work-in-progress, but I thought I’d put it out there because it may be interesting to others who use the tool.

This is a “teaser” in that I’m not done writing the content yet, but I wanted to get it out there as “something I’m working on”.  The problem at-hand is that we have a table trigger which is constantly being disabled/enabled by a stored-proc , which in turn controls the only acceptable method of updating the columns that would otherwise be forbidden from update by said trigger.  Clear as mud?  K.  Basically there’s a schema change (“drift”) of a certain specific type that I want DLM Dashboard to always ignore on this DB.

Some code:

USE RedGate;

SELECT TOP 100 * FROM RedGate.SQLLighthouse.DDL_Events de
ORDER BY de.PostTime

SELECT TOP 100 * FROM RedGate.SQLLighthouse.DDL_Events de
WHERE de.appname NOT IN ('SQLServerCEIP', 'Spotlight Diagnostic Server (Monitoring)')
AND de.appname NOT LIKE 'SQLAgent%'




CREATE INDEX IX_DDL_Events_SPID ON RedGate.SQLLighthouse.DDL_Events
 INCLUDE (transaction_id, options, nestlevel);
CREATE INDEX IX_DDL_Events_AppName ON RedGate.SQLLighthouse.DDL_Events
 INCLUDE (client_net_address);


CREATE XML INDEX XI_DDL_Events_EvenData_PATH ON SQLLighthouse.DDL_Events
