Hello raja567 this qustion has noting to do with Env variables..

Anyway i read the following in the docs of DBI:

selectrow_array

..

If called in a scalar context for a statement handle that has more tha
+n one column, it is undefined whether the driver will return the valu
+e of the first column or the last. So don't do that. Also, in a scala
+r context, an undef is returned if there are no more rows or if an er
+ror occurred. That undef can't be distinguished from an undef returne
+d because the first field value was NULL. For these reasons you shoul
+d exercise some caution if you use selectrow_array in a scalar contex
+t, or just don't do that.

print out your consolidatedPath to see what it holds: if the -d test fails i guess it is not a directory..
In addition even if you'll be able to have back the value "$P2KTMP/data" where this dir is located? is a relative path? is the same relativness of your program?
