Hi All,
My First post so i hope Im in the right place!

I'm trying to call an oracle stored proc (never done it before) and Im having a spot of bother I've searche dfor a few days and tried various things but nothing seems to work!

The error:
ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'DRL_BY_DEPT'
ORA-06550: line 1, column 7:

Stored Proc is:

Stored procedure name: drl_by_dept
Oracle Package pmc_pkg
Data Type Length
Input Parameters p_start_dt The start date of the DRL calculation period. VARCHAR2
p_end_dt The end date of the DRL calculation period. VARCHAR2
p_shift_cd The shift code of the DRL calculation period. NCHAR 1
Output Parameters p_bpd_nm The department name VARCHAR2 30
p_defect_cnt Sum of DRL_RATIO INT
p_target The DRL target value for the period. NUMBER (5,2)
p_drl Direct Run Loss (DRL) NUMBER (6,2)
p_veh_cnt Number of vehicles inspected at the DRL count point during calculation period. INT

Hope that looks better when I submit the thread now for my code:-

There's alot of commented stuff in there from trial n error....lol
