Reporting Services 2008 Configuration Mistake

To start working with the management side of SQL Server Reporting Services 2008, I decided to set up a report server and report manager. Unfortunately, I made a mistake while setting up my configuration that left me a little perplexed. Here are the steps I took to cause, track down, and solve the issue. Problem: I began by opening the Reporting Services Configuration Manager from the Start Menu. I clicked through each of the menu options and accepted the defaults for any question with a warning symbol, since warning symbol typically designate an action item. After two minutes, all of the warning symbols had disappeared, and I was ready to begin managing my report server. Unfortunately, opening up a browser and trying to open up the report manager resulted in the dreaded " The report server has encountered a configuration error. (rsServerConfigurationError) " message. Sherlock-ing it: I put on my sleuthing hat and went to the log file directory: C:\Program Files\Microsoft...

Execute SQL Task Designer Limit

After migrating a package from DTS to SSIS, I had a problem with an Execute SQL Task. I couldn't change any characters in the SQLStatement property; I couldn't add any new characters; I could delete characters, but not retype them! After googling several variations of "integration services" "read only" and "Execute SQL Task", I deleted about half of the entry in a fit of frustration. Lo and behold, I could type again. Apparently, there is limit on the size or number of characters that can be entered in the SQLStatement property. From my experimentation, I came up with a limit of 32767 characters. The interesting thing is that the restriction only seems to be on the designer. If you set the SourceType to "Variable" and use a variable that contains more than 32767 characters, the task will execute. Also, if you use the "Direct Input" SourceType and modify the package XML to set the SQLStatement longer than 32767 characters, ...

Manipulating Excel Spreadsheets in SSIS

Tom, an attendee at last weekend’s SQLSaturday Olympia , asked me how to refresh a spreadsheet from within SQL Server Integration Services. My first thought was to turn on the connection’s “Refresh data when opening the file” option in the spreadsheet itself and avoid the situation entirely; however, this may not always be a viable solution. Here are the steps to perform the refresh from within an SSIS package. First, ensure that Microsoft.Office.Interop.Excel is registered in the GAC. If not, install the 2007 Microsoft Office system Primary Interop Assemblies . This will need to be done on any machine where you plan on running this package. Next, create a script task in your SSIS package that contains the following code (include your spreadsheet name): Imports System Imports System.Data Imports System.Math Imports Microsoft.SqlServer.Dts.Runtime Imports Microsoft.Office.Interop.Excel Public Class ScriptMain Public Sub Main() Dts.TaskResult = Dts.Results.Success Dim excel...
