You will want to use dynamic SQL to change the DB you are executing the query in: DECLARE @dbname AS VARCHAR(100) DECLARE @query AS VARCHAR(MAX) SELECT @dbname = name FROM sys.databases d WHERE /*enter criteria here to get DB*/ SET @query = ' use ' + @dbname + ' /*enter your query here*/ ' PRINT @query EXEC(@query)


You could use a RS.exe script. This would allow you to create a script, a batch file and a set of .rdl files. Then you just call rs.exe with the script you created to upload the files to the report server. You can find an example here
