Why does modifying a Query causes all fields in the dataset to disappear in the Report Data pane

Posted By:      Posted Date: October 22, 2010    Points: 0   Category :Sql Server

We routinely import reports from Microsoft CRM and amend them in Visual Studio 2008 eg to add column totals, change layouts etc

If the report needs more fields from CRM, I amend the SQL query in the CRM Dataset, adding the new field references (rather than recreate the report in CRM with new fields, import into  VS2008 and redo all  the formatting etc).

This worked fine until this week.

Whenever I modify the SQL query in the CRM Dataset, all the fields in the Dataset disappear in the Report Data pane.

Even changing a character in a field name which isn't used in the report - which should have absolutely no impact on the report - causes the fields to disappear.

As far as I'm aware, nothing has changed on our systems.

We use SQL 2008 reporting services and Microsoft Visual Studio 2008.

Any suggestions greatly appreciated!

How to query for id's of the fields with List Data Retrival Services Query() web service

Since i marked a post as answer in my previous topic, it seems that people dont visit the topic anymore as they see it as "answered" while it actually is only partially answered. So i guess i have to ask again in a different topic.    I need to get data from Sharepoint Server (3.0 i belive) for my Integration Services project. For that i use Sharepoint's webservices. I've read tutorials and downloaded sample programs to talk to WSS web services. I realise i have two ways to get items in a list: Use Query() or GetListItems(). Problem is, GetListItems() has a mandatory "Row limit" field and i might have to import ALOT of fields, so i thought Query() is better for me.  But, when using GetListItems(), the WSS returns the ID of the fields (for example, for a field of type user, something like "395;Ivanov Ivan Ivanovich" is returned) but when using Query() for the same list, WSS returns only the field value ("Ivanov Ivan Ivanovich") without the ID. I need it to return the ID as well. How can i set it up, on my side or server side, so i would receive the ID's, not only the values of the fields that are actually linking to something by ID when i use Query() web service?

SSRS 2005 Report Writer Limitation- 128 Max Length for Query Strings Constructed in Data Tab???!!!


I'm trying to construct a SELECT query within the Report Writer 2005 Data Tab as follows- ="SELECT blah..." & SomeFunctionToConstructWhereClause() " ORDER BY 1"

When the length exceeds 128 characters, I get the following error (works otherwise)- Microsoft Report Designer Incorrect syntax near '='. <QUERY TEXT> The identifier that starts with is too long. Maximum length is 128.

Say it isn't so or that there is a reasonable workaround for this. 128 characters isn't that much when you're talking about complex query strings. Thanks in advance.

Passing report parameters to a query using a WCF data source


Hello everyone,


I am attempting to pass report parameters to my query. My report's data source is a WCF web service. I can run normal queries fine, but I have found that without the know-how to pass parameters to my query I am limited with my capabilities.

Assume a string parameter named "Name" with a specified default value of "Jmachol90", how would I pass that into the following query at the designated place:




          <Method Namespace="http://schemas.microsoft.com/sqlserver/masterdataservices/2009/09" Name="SecurityPrincipalsGetRequest">


          <Parameter Name="Criteria" Type="XML">









MS SQL Server: Search All Tables, Columns & Rows For Data or Keyword Query

If you need to search your entire database for specific data, this query will come in handy.

So when a client needs a custom report or some sort of custom development using Great Plains, most of the time I will have to track down the data in the system by running this query and find the table(s) it is in.

Create ID (uniqueid?) from two fields when data is entered


I need to create an ID from two fields when they are entered into the db for the first time.  I thought Uniqueidentifer would do this, but it looks like uniqueidentifier is random and i have no control of the process. 

My user will enter 4 letters into a column called INIT and 4 numbers into a column called NUMB.  What I would like to do is create an id by combining those fields.

How can I do this?

ADO.NET: Tackle Data Concurrency Exceptions Using the DataSet Object


ADO.NET provides many techniques for improving the performance of data-intensive applications and for making them easier to build. The DataSet, the hallmark of the ADO.NET object model, serves as a miniature, disconnected facsimile of a data source. While using the DataSet improves performance by reducing expensive trips to the database server, it also introduces the possibility of multiple users attempting to change the same data simultaneously, thereby generating data concurrency exceptions. This article examines the common causes behind data concurrency exceptions and presents techniques for overcoming them.
