Thanks for this interesting QOD.
I have been able to select the good choice only because I have read the documentation of the next SQL Server version ( 2016 ) last month ( to rediscover the novelties ).
An old language which seems to be be like APL ( an old language that I have used long time ago on a HP 3000 , around 30 years ago... )
But I am wandering why Microsoft has chosen this language when it seems that it is being replaced by Python ( especially when Python is supported by Visual Studio 2015 )?
