Author  Topic  kmishle Starting Member 2 Posts Posted - 2006-06-08 : 16:49:36 Hi All, I'm quite new to SSRS (and .net development as well) so any help would be useful. My problem is this: I'm running a report from a Sybase ASE datasource to pull data into a table control. One of the fields I'm pulling in is called assignment group. Now, in the same report output I also need to display who the manager of that group is... unfortunately this information is not stored in the same database. We store the manager information in a completely seperate Oracle database. So, I need some method of 'linking' the data from my Sybase dataset to a table in Oracle and I can't quite figure out how to go about it. Every record would have a manager and there could be 10k records returned so I need to be carefull about performance issues. I was starting to go down the path of creating a .net dataset in a custom assembly which would be filled via a query to the Oracle database. What I was thinking is to create and fill a dataset with my lookup data from Oracle then, in the report, call a function from the table control which would search through the dataset in memory and return the actual manager name. Am I on the right track or am I overcomplicating the solution? Will this be too inefficient from a performance perspective? Would a subreport be a more efficient solution? Also note that I need to be able to export the output to Excel, as well as display the results from the report viewer.
