Resolve variable inside another variable

Corona,
Thanks for the reply.
I am sorry that you had ask it again
. I thought instead of explaining the whole problem statement , it would be good if I just ask what is it that I am facing problem which is resolving parameters.
Here is the actual problem statement I am trying to solve.
I have a SQL query. This query has variables which I want to resolve at run-time.Query is itself a variable. And the parameters(variables inside it) for this Query will be assigned values just before I write the command(This command I am struggling with) to resolve the Query.
Once the Query is resolved I will put that in command line (m_db command).
During this process I have faced problem which I stated.I hope my previous post will make you sense now.
Could you please help me out with below two problems:
1. How to overcome this error : variable name too long
2. How to retain single quote character while resolving variable.
(I have given detail with example in previous post)
I am using Korn Shell.
Thanks,
Vinay

Hi
I have a variable which is a path ie:
UBERROR=/cobwrk/mchr/prodsup/ub/wrk/../error
