I am looking for a software package to automate deployments of SQL scripts (procedures, tables, etc.), and SSIS packages for SQL Server. We don't need to compile JAVA code, or package .DLLs in a deployment. I just want to widen the pool of folks able to hit a button and deploy a pre-defined deployment. I am debating trying to write one myself, as it is just SVN, SQLCMD, and move commands, but if a package already exists (and is supported), that would be much easier. What do the rest of you folks use for these things?
