Stored procedure returning multiple records without using SYS_REFCURSOR

Question

Hello,
I am new to oracle stored procedures, have done stored procs in SQL server in past. I am trying to write single stored proc which will return multiple records. I have the stored proc as below and that is compiled without any errors.
We don't want to use SYS_REFCURSOR as output param b'coz the place from which this proc is gonna call, that system doesn't support SYS_REFCURSOR param.
create or replace
PROCEDURE p_get5500DATA_MB (
IN_plan_ID IN T_5500DATA_QWP.Plan_ID%TYPE,
IN_plan_ID_col OUT T_5500DATA_QWP.Plan_ID%TYPE,
p_SEQNUM OUT T_5500DATA_QWP.SEQNUM%TYPE,
p_HEADER_CD OUT T_5500DATA_QWP.HEADER_CD%TYPE,
p_VALUE1 OUT T_5500DATA_QWP.VALUE1%TYPE,
p_VALUE2 OUT T_5500DATA_QWP.VALUE2%TYPE
) AS
BEGIN
SELECT
Plan_ID,
SEQNUM,
HEADER_CD,
VALUE1,
VALUE2
INTO
IN_plan_ID_col,
p_SEQNUM,
p_HEADER_CD,
p_VALUE1,
p_VALUE2
FROM TRS1DBO.T_5500DATA_QWP
WHERE Plan_ID = IN_plan_ID
ORDER BY SeqNum;
-- EXCEPTION
-- WHEN OTHERS THEN
-- RAISE_APPLICATION_ERROR(-210001, 'Error in fetching data from T_5500DATA_QWP....');
END;
Error:
ORA-01422: exact fetch returns more than requested number of rows
ORA-06512: at "TRS1DBO.P_GET5500DATA_MB", line 10
ORA-06512: at line 11
My questions is:
- What would be the best practice for this type of simple stored procedures?
- Is there any alternate or is there anything i can fix in above stored proc which return multiple records?
Thank you,
Vimal

Just out of curiosity, what are you using for API or driver that doesn't support a ref cursor? Ref cursors are pretty much the defacto standard for passing multiple records out of an Oracle procedure. Oracle's ODP.NET, OLEDB, ODBC, JDBC, OCI, all support ref cursors. Chances are that if the driver you're using doesn't support something as basic/fundamental as a ref cursor, it's probably also not going to support something else either.
You'll most likely want to check with the driver/api vendor on their recommended approach.
