I think he's trying to use it as a PL/SQL variable -- not
a table name. As in this block of PL/SQL code in the
DBD::Oracle docs:
FUNCTION func_np
RETURN VARCHAR2
IS
ret_val VARCHAR2(20);
BEGIN
SELECT USER INTO ret_val FROM DUAL;
RETURN ret_val;
END;
In this case the PL/SQL code is selecting from a table into
a variable.
The stuff below looks like an attempt to create on the fly
PL/SQL. I've never seen that done.
