• These titles (SQL Server Developer, DBA) are so generic that a blanket statement like that doesn't really help. Just start looking for a job and see what activities and responsibilities show up under a help wanted add for a DBA.

    In some companies, SQL Server Developers are just developers who can query a database. In some companies, DBAs just make sure that the backups ran last night, etc.

    Sometimes, SQL Server Developer is a title for someone who knows SQL Server inside and out and optimizes, tunes, etc. In some companies, DBAs do both t-sql development and administration, and much more.

    My title is DBA, but I do some coding, some database administration (server jobs, manage security, add users, etc.), and a lot of performance tuning and research.

    Like I said above, the titles and responsibilities just vary too much from company to company to use a blanket title to define what a person is capable of.
