select from dynamic table names

From
Dinesh Kumara
Date:
I have 16 tables which created according to generated MD5 hash.
At the time of execution i tried to retrieve data from a table where table name id dynamic.

table name can be expertdb.rate_AVAIL_[0 to F]

I tried to get this from ;
SELECT * FROM expertdb.rate_AVAIL_ || upper(substring(md5('2011-11-10')from 1 for 1))

but it is giving an error that is error with '||' appender. please someone give me an idea..

you can't do it on SQL level - column and table names must be constant
