Re: Difference between the Two statements Declare and Set2013-03-11T05:27:52Z in response to SystemAdminHi Vivek,
There is a small difference between declare and set :
SET : Using this statement we are setting a static value to ref1 variable.
DECLARE : Using this statement we are actually creating a pointer in the logical tree. A variable defined using declare can be moved across a logical tree unlike a SET statement which sets a static value.
I hope this makes clear .
