MCSA SQL Server 2012 wont do you any harm:
70-461 Querying SQL Server 2012 (will teach you a little bit more than the basics about data querying)
70-462 Administering SQL Server 2012 (installation, management, clustering, failover, etc, good to know if you manage the servers as well)
70-463 Implementing a datawarehouse using SQL Server 2012 (building ETL packages with SSIS, data quality management, hmm,, doubt you will ever use this as support.)
As others have said, you will get a piece of paper saying you know learned this stuff, and it could get you’re foot in the door as a junior SQL developer or DBA, but only doing the job will teach you how to do the job.
Drop me a mail if you decide to do it, I have some learning material I can share.
