Hi nkm,
The solution suggested above only returns 'mm-yy' if I am right where as what is desired is 'ddd-yy'. Perhaps the above sql should have been
select substring(convert(char(8),getdate(),10),4,8)
so that we atleast get date in the 'dd-yy' format. But that still does not seem to solve the problem because if I am right the character version of the day of week is sought. I would suggest the following sql as of now. Hope it helps.
select substring(DATENAME(dw,getdate()),1,3) + "-" + substring(DATENAME(yy,getdate()),3,2)
All the best,
Vijay
