Oracle Error Message
ORA-37158: Bad clob or varray IN-args: (case string)
Reason for the Error
When in clob or varray mode, the PL/SQL mappings of OLAP API’s IDL interface methods were executed blindly with null clob/varray or non-null clob/varray containing garbages.
Solution
Do not blindly execute them as doing so does not make sense unless you understand how OLAP API works internally.
