Take a look at the documentation and examples again:
http://www.postgresql.org/docs/8.2/interactive/plpgsql-control-
structures.html#PLPGSQL-RECORDS-ITERATING
There are two forms to iterate over the query:
1. FOR target IN query LOOP
2. FOR target IN EXECUTE text_expression LOOP
In your code you have mixed the two together. You appear to be trying
to concatenate a string on to the end of a query expression. My
suggestion is to eliminate the string you created (_WHERECLAUSE) and
add the proper conditions to the query expression you already have.

This is probaly a triviel question but i'm new to plsql, so this is a
