I have a following oracle stored procedure
CREATE OR REPLACE
PROCEDURE getRejectedReasons
(
p_cursor IN OUT SYS_REFCURSOR)
AS
BEGIN
OPEN p_cursor FOR SELECT * FROM reasons_for_rejection;
END;
However, when I run this stored procedure in sql-developer then I dont see anything. I just see something like this:
Connecting to the database oracleLocal.
Process exited.
Disconnecting from the database oracleLocal.
I'm coming from MS sql server and am used to seeing actual results when running a stored procedure like this. Is this stored procedure not returning results because I am using a cursor??
The stored procedure is returning something it's just you aren't doing anything with the results.
You can do this simply by running the following script in SQLDeveloper:
VARIABLE csr REFCURSOR;
EXEC getRejectedReasons(:csr); -- the colon identifies the parameter as a variable
PRINT csr;
Another method is to fetch each row and do some sort of processing:
DECLARE
-- sys_refcursor is weakly typed
refcsr SYS_REFCURSOR;
-- define a record so we can reference the fields
rej_rec Reasons_for_Rejection%ROWTYPE;
BEGIN
getRejectedReasons(refcsr);
-- loop through the results
LOOP
-- gets one row at a time
FETCH refcsr INTO rej_rec;
-- if the fetch doesn't find any more rows exit the loop
EXIT WHEN refcsr%NOTFOUND;
-- Do something here.
-- For example : DBMS_OUTPUT.PUT_LINE(rej_rec.reason_desc);
END LOOP;
END;
