I have 3 parameters that a procedure receives, how do I pass the values for the variables err_buff and ret_code ?, as null ?, I mark the errors of invalid number of parameters
PROCEDURE XX7E_EXT_FAC(err_buf OUT VARCHAR2,ret_code OUT NUMBER, P_TRX_NUM VARCHAR2, P_CUST_NAME VARCHAR2, P_CUST_ID VARCHAR2);
PLS-00306: wrong number or types
