Calling stored proc (with 2 IN and 3 OUT) - from SQL Plus

Question

This is the signature of my stored proc:
CREATE OR REPLACE PROCEDURE myschema.myproc
   p_usr_name     IN  VARCHAR2,    
   p_send_tmstmp  IN  DATE,    
   p_ret_value    OUT NUMBER,
   p_err_code     OUT VARCHAR2
)If I need to call it from sql plus, how do I need to pass the arg?
This is what I am doing
execute myschema.myproc('abc123','02-MAY-2008');
What is wrong here? If someone could help. Thx!

Answer 1

Try something like this
var usr_name    varchar2(30)  
var send_tmstmp varchar2(11)  
var ret_value   number
var err_code    varchar2(10)
begin
:usr_name    := 'abc123';
:usr_name := '02-MAY-2008';
myschema.myproc ( p_usr_name           => :usr_name,
                  p_send_tmstmp        => TO_DATE( :usr_name, 'DD-MON-YYYY' ),
                  p_ret_value          => :ret_value,
                  p_err_code           => :err_code);
end;
print ret_value;
print err_code;
