Creating a report from multiple data sources

Posted By:      Posted Date: September 16, 2010    Points: 0   Category :Sql Server
I am working on a report where it requires pulling data from various sources, databases and data exported into excel sheets from different databases. The objective of the report is to create a single report with all the Providers (HPs) that have been terminated. So what I have done is that I have exported all the data on a local server in the pubs database and I am using a TSQL query to return the report. The same providers may exists in the various data sources so I have to make sure that I am only returning the data once...how ever the challenge is that, other than FirstName and LastName, there are no consistent IDs that we can use in all. For example, not all of the records have the SSN, PhoneNumber, or other IDs that uniquly identify the record. I have to create a report that returns the result set and identifiys the matching records and the source system the data is from..for example the output should display as such: Termed System firstname lastname SSN homephone phonenumber Active System AMIE Jeannine Donigan NULL 3522631007 Nurse SL Linde Peggy Vanrensselaer NULL 6077321218 Sbdev Below is the approach I I have taken to return the data and I wanted to know if there is a more efficient and better way of doing this: DECLARE @matchingTerminated Table ( FirstName Varchar(255), LastName Varchar(255), Gender Varchar(255), SSNEncrypted varchar(255), Birt

What are my options when I need to create a report with data from multiple sources?

Hello all,  What are my options when I want to create a report that will get records from multiple data sources based on data from a parameter? The user will enter the customer ID, I have to check that ID against 5 different data sources. Have you guys done anything similar? Should I leverage SSIS on this request, adding an extra layer of complexity? Should I do this all from SSRS? What are my options?

Does Microsoft plan to enhance SSRS to allow access to multiple data sources?

We have the need to join multiple data sources into one table in SSRS.  At present, as I understand it, this is not a part of current delivered functionality.  We get around it by creating links withing the source database to access other databases.  The links themselves have their own set of constraints and performance issues. The other option is to use sub reports.  It would be nice to be able to define connections to disparate databases to join data from multiple data sources.  Does Microsoft have plans to deliver such functionality in an upcoming release of the SSRS product?
