您通过仅传递两个参数来调用具有四个参数的过程，没有默认值。

这是如何调用您的程序的示例：

declare
    V_AGE              NUMBER;    
    V_OCCUPATION       VARCHAR2(10);
    V_LASTSTATEMENT    VARCHAR2(10);
begin
    GET_SINGLE_CUSTOMERINFO (
                                P_ID               => 1              ,
                                P_AGE              => V_AGE          ,
                                P_OCCUPATION       => V_OCCUPATION   ,
                                P_LASTSTATEMENT    => V_LASTSTATEMENT
                            );
end;

或，带变量：

SQL> variable V_AGE           number;
SQL> variable V_OCCUPATION    varchar2(10);
SQL> variable V_LASTSTATEMENT varchar2(10);
SQL> exec GET_SINGLE_CUSTOMERINFO (P_ID => 1, P_AGE => :V_AGE, P_OCCUPATION => :V_OCCUPATION , P_LASTSTATEMENT => :V_LASTSTATEMENT );

PL/SQL procedure successfully completed.
