SSRS报告切换数据源

Question

I am using SSRS reports and now I want to change data-source base on parameter. I had all ready tried to create a dynamic data source base on parameter and it works perfect on our local environment. But on production we are not able connect database due to security issue.

To overcome the security issue. we had created two data source "ProdDB" and "ArchDB" in reporting server and map with my report's data source

Now I want to know how we can Switch data source base on parameter like Report parameter @dbsource = "Prod"

if @dbsource.value = "Prod" then 
  datasource = "ProdDB
Else 
  DataSource = "ArchDB"

Answer 1

Here is what you can do

1. Create two report parameters as databaseName and DatabaseServer

2. in datasource-> properties -> connection String -> expression write a connection string as below

="Data Source=" + Parameters!databaseServer.Value + ";Initial Catalog=" + Parameters!databaseName.Value

This will ask database name and database server as a report parameters, if you are running the report as data driven subscriptions you can pass these parameters dynamically from a query or static subscription parameters.
