Answer:
The GetComputerName() function will not work in the MS SQL Data Link Properties. However, once you have created a connection string, you can replace portions with a variable or expression.

We have a goal in our organization of just changing the Agent on the Workflow and having that job run correctly on our dev/uat/prod lifecycle machines. I understand how to do that for disk references by using agent variables to handle the drive references for running programs and file references. But I'm having a little trouble having the connection string to our ms sql databases dynamically point to the correct database server based on the agent machine. When I build the task with no agent machine assigned not much choice comes up in terms of connection strings. When I go into the task through the Workflow editor with an Agent assigned I get the Agent Connection strings for that environment. But that makes me suspicious that if I changed the Agent in the Workflow whether it would work at runtime and switch over to the other database server. So is this possible and if so how do you specify the connection string so it can be dynamic? Or to put this question a little differently, if I had two identically named pre-defined connection strings (say defaultDBServer) on two agents, if I switched the Agents on the task, would that switch the database the task connected to?
