Negative value in LEFT function cause error

Hello,

I have some sql code (I did not write it) that uses negative argument values in the left function. But when I run the code I get an error. Like this:

Code: Select all

dbadmin=> select left('The small pig', -3);
ERROR 4039:  Negative substring length not allowed
Is there a work around for this?

Thanks!

Need to add days to a date, excluding SAT and SUN

Hi gurus,

I have a need to add X days to a date but exclude adding any Saturday or Sundays. Today is 11/14/2013. I want to add 12 days. The result I would like is 12/01/2013 (Monday) and not 11/26/2013 (Tuesday).

Is there a simple way to accomplish this in Vertica SQL?
