I've begun learning Sql Server 2012 and i'm just loving it.
I'm a budding DBA/Designer and as i'm learning this platform it has occurred to me that i should get my feet wet into 2008 if anything but to learn upgrade and migration between the two platforms.
But i've been wondering if i should go back even further to 2005 and touch on it as well ?
I guess what i'm really wondering is there substantial t-sql differences between 2005 and 2012 ?
I've been learning Oracle in parallel but i think i'll switch mostly to SQL Server since it's so damned fun.
I hope you guys can give me some tips.
Thanks for any assistance,
