Question

I am using the following query to return a single value:

select er.elig_code
from idm_elig_rule er 
where ER.ROLE_CODE = role_code and ER.SERVICE_CODE = service_code; 

When I substitute values for the variables and run it as a single SQL statement it will return just a single value like I want it too. However, when I place the statement in a cursor and loop through the results, it returns all rows in the table. I’ve also tried a “select into” statement but that still returns all 85 rows in the table. I have a unique index in the idm_elig_rule table that is a combination of the role_code, service_code and another column.

EDIT: Here’s how I’m testing it out – using an anonymous block:

declare
    role_code_in IDM_ELIG_RULE.ROLE_CODE%type := 'CEMP';
    service_code_in IDM_ELIG_RULE.SERVICE_CODE%type := 'PORTL'; 
    cursor get_elig_code is 
        select ER.ELIG_CODE
        from idm_elig_rule er 
        where ER.ROLE_CODE = role_code_in and ER.SERVICE_CODE = service_code_in; 
begin 
    for r in get_elig_code 
    loop
        DBMS_OUTPUT.PUT_LINE(r.elig_code);
    end loop;  
end;

EDIT: I changed the names of the variables in the where clause and that resolved the issue.

You have a Name Resolution issue with your variable names since the bind variable names are the same as the column names. Change your variable names to avoid the PL/SQL compiler from deciding for you.
