Check the input Query syntax from VB.NET

I've created one procedure in that I've used the ref cursor which is defined in the DBK_REPORTS Package. The input parameter for this procedure was my input query and the output parameters are queryresult as cursor and message. What I did is, within the try..catch block, I've opened this refcursor for my input query and if any syntactic errors occurs which will be Exception under the condition OTHERS, and it'll be stored to the output parameter message. It was done by assigning the result of SQLERRM function.

create or replace package DBK_REPORTS 
is
TYPE record_type IS REF CURSOR;

create or replace PROCEDURE DBP_QUERY_RESULT
       (  
          
          O_QUERY               IN   CLOB,
          O_QRY_RES             OUT  DBK_REPORTS.record_type,
          O_MESSAGE             OUT  VARCHAR2
      )IS
 
V_QUERY            CLOB;
BEGIN
V_QUERY := O_QUERY;                        
   
      BEGIN
           OPEN O_QRY_RES FOR TO_CHAR(V_QUERY);
          
        EXCEPTION
          WHEN NO_DATA_FOUND THEN
            O_MESSAGE := 'NO RECORDS FOUND';
          WHEN OTHERS THEN
            O_MESSAGE    := sqlcode || sqlerrm;
                     
       END;
                         
END DBP_QUERY_RESULT;
