As elaborated in the article we are in the process of developing a BIP report identified as a Procedure Call. An input parameter of type String has been included in the report. However, we are experiencing the following error when attempting to run the report.

java.sql.SQLException: ORA-06550: line 10, column 41: PLS-00306: wrong number or types of arguments in call to 'CAST_TO_RAW' ORA-06550: line 10, column 5: PL/SQL: Statement ignored ORA-06550: line 16, column 8: PLS-00456: item '2' is not a cursor ORA-06550: line 16, column 3: PL/SQL: Statement ignored

Following is the code that we have in the report

Parameters:

Name: P_QRY
Data Type: String
Parameter Type: Text

Data Model:

DECLARE 
  l_query VARCHAR2(32767);  

  TYPE ref_cursor IS REF CURSOR;
  l_result_set ref_cursor;
BEGIN 
  l_query := UTL_ENCODE.BASE64_DECODE(UTL_RAW.CAST_TO_RAW(:P_QRY));
 
 OPEN :l_result_set  
  FOR UTL_RAW.CAST_TO_VARCHAR2(l_query);
END;

Error:

We would be grateful if anyone could provide guidance on how to resolve this matter.
