HI. I have been oracle developer/DBA for 9 years. Recently start to also work on SQL server as SQL server developer. For my day to day job, I don't have issue. I can google around or read a T-SQL fundmentals book to get my job done. However, that may not be good enough for my performance goal this year. I need to find a way to proof that I "learn" and "own" the SQL server skill for my job as a developer. A way to proof it like pass a exam or take an course ( without budget ). In my case, Is there any cost reasonable online course I can take to proof that I "can" develop in SQL server ( we only use T-SQL and SSIS only )? Any exam/certification I can take ?
