Variable Connection String For OLE DB Connection

Good Morning,



I hope that I am just missing a step in the process somewhere. I have established a string variable called DatabaseServer and another called DatabaseName. In the OLE DB connectionstring expression I have the following:




Code Snippet

"Data Source=" + @[User::DatabaseServer] + ";Initial Catalog=" + @[User::DatabaseName] + ";Provider=SQLNCLI.1;Integrated Security=SSPI;Auto Translate=False;"



My understanding is that changing the variable from SERVERA to SERVERB should repoint the connection. (Test to pre-production to production in my current promotion environment.) This should also take effect in any dataflow task using the database connection above right? When I try to repoint the server variable (and only the server variable) I am either a.)throwing errors saying the original connection cannot be found in the data flow task, or b.)the job appears to be processing fine, but the repoint did not take place and data is still flowing to the original server.



Can anyone offer suggestions as to what I am missing?



The properties values in the DB connection:

ConnectionManagerType is OLEDB

DataSourceID is blank

DelayValidation is False (Setting to true changes nothing in my test)

Expression for ConnectionString is (see above)

RetainSameConnection is False

SupportsDTCTTransactions is True (and appears to be unchangeable.)
