Re: Using SPLIT with DOT(.) delimiter demonstrate funny behavior within a VIEW

2015-08-24 Thread Sanjay Subramanian
Hi Vivek
Thanks A few more experiments 
The \\ , \\\ and  all work correctly if used as following 
split(reverse(split(reverse(floc),'/')[0]),'[\\.]')[0]   (need those square 
brackets)
split(reverse(split(reverse(floc),'/')[0]),'\\\.')[0]  (does not need square 
brackets)
split(reverse(split(reverse(floc),'/')[0]),'[.]')[0]   (need those square 
brackets)

Hi Sanjay,
Try replacing the 4 backslashes with just 2. Usually works with 2 backslashes.
Replace this split(reverse(split(reverse(floc),'/')[0]),'.')[0] as resid    
     with split(reverse(split(reverse(floc),'/')[0]),'\\.')[0] as resid

Please have a look and let us know if that helps.

Hi Sanjay,

Try replacing the 4 backslashes with just 2. Usually works with 2
backslashes.

Replace this *split(reverse(split(reverse(**floc**),'/')[0]),'.')[0]*
as resid
with *split(reverse(split(reverse(floc**),'/')[0]),'\\.')[0]* as
resid

Please have a look and let us know if that helps.
