How to pass multiple parameters to Query using START WITH, CONNECT BY OBIEE

Question

Hi
I have following oracle query which need to be used as a Data Source in OBIEE Physical Layer. I guess I have to create stored proc. How do I implement this in OBIEE RPD and how do I implement the respective Dashboard prompts for the parameters.
SELECT
CIRC.PATH_NAME, CIRC.BANDWIDTH , CIRC.CATEGORY, CIRC.CUSTOMER_ID,
CIRC.STATUS, CIRC.CUSTOMER_NAME,
QUER.LEV
FROM
CIRCUIT_PATH circ, VAL_CUSTOMER cust,
( SELECT
DISTINCT CIRC_PATH_INST_ID, LEVEL LEV
FROM
CIRC_PATH_ELEMENT
START WITH
CIRC_PATH_ELEMENT.CIRC_PATH_INST_ID IN ( SELECT
DISTINCT CIRC_PATH_INST_ID
FROM
PORTS a
WHERE SITE_NAME = @variable('Enter a Site Name')
AND CARD_SLOT = @variable('Enter a Card Slot')
CONNECT BY
PRIOR CIRC_PATH_ELEMENT.CIRC_PATH_INST_ID =
CIRC_PATH_ELEMENT.PATH_INST_ID
AND ELEMENT_TYPE != 'K' ) QUER
WHERE
circ.circ_path_inst_id = QUER.CIRC_PATH_INST_ID
and circ.cust_inst_id = cust.cust_inst_id (+)
ORDER BY
LEV DESC , CIRC.PATH_NAME ASC, CIRC.BANDWIDTH ASC
Thanks

Hi John
Thanks. I looked at your URL. I do have package. Just using procedure. So my initialization string (For stored proc in Physical Layer of RPD) is
exec demo.add_employee(VALUEOF(NQ_SESSION.empid1));
But when I run request in Answer I get the error
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 17001] Oracle Error code: 900, message: ORA-00900: invalid SQL statement at OCI call OCIStmtExecute: exec demo.add_employee(105); . [nQSError: 17011] SQL statement execution failed. (HY000)
What should I put in initialization string in RPD?
Thanks
