Question

I have a stored procedure that updates records if they exist, or adds a new record if they don’t exist.

SQL:

CREATE OR REPLACE PROCEDURE ADDRECORD(ihost VARCHAR, iip VARCHAR)
AS 
   rc VARCHAR(4000);
   ROWCOUNT NUMBER;
BEGIN
   rc := 'select count(0) from myTable where physical_host =  ihost and primary_ip = iip';
   ROWCOUNT := to_number(rc, '99');

   IF ROWCOUNT = 1 THEN
      UPSERTRECORD(ihost, iip);
   ELSE
      INSERT INTO myTable(PHYSICAL_HOST, PRIMARY_IP)
      VALUES (ihost, iip);
      INSERT INTO IP (IP, IP_IND) VALUES (iip, 'V');
   END IF;    
END ADDRECORD;

The UPSERTRECORD is another stored procedure that is being called. It works fine. In fact, the error is occurring on the line that contains the to_number. The error is :

ORA-06502: PL/SQL: numeric or value error: character to number conversion error 

Is there another way to do this? Sorry, I’m not super experienced with SQL, but I need to get this figured out.

Answer 1

Do

DECLARE rowcount As Number(38)
select count(*) INTO rowcount from myTable 
where physical_host =  ihost and primary_ip = iip
