Visual Studio - DB solution Organizing

All, I am trying to set up a database solution of an existing database into TFS. One of the challenges i have is setting up synonyms. Since Synonyms vary for environment i wanted to set up it dynamically. I tried creating a synonym like the below , but it dint let me have if conditions. Can I create them as pre deployment scripts ? or how to best do it ? Also I need suggestions on release management . How do i create incremental release from the solution ? Thanks in advance .. If ( @@servername = 'dev' ) BEGIN CREATE SYNONYM x END ELSE If ( @@servername = 'qa' ) BEGIN CREATE SYNONYM y END ELSE If ( @@servername = 'prod' ) BEGIN CREATE SYNONYM z END
