No bro... that is not true that any developer can do a sql server dba or dev work... SQL SERVER is not that all can touch..either you must be DBA or DEV for SQL Server.If you are SQL DEV then hardly you touch the SQL SERVER PROD server...Only Ops or SYS DBA can manage the SQL SERVER real prod server... So forget that any developer can do sql admin job.. that can be possible if company is very very small and want one person to handle all and that is very rare case...
