如何使变量保持从一个过程中获取的值，以便在plsql中的另一个过程中使用

Question

我有一个包含两个程序的包 在同一个包中。

1. p_set_values (pn_id_number IN number)
2. p_get_values (prc_records OUT sys_refcursor)

p_set_values (pn_id_number IN number)   将数据插入my_table，其中id_number = pn_id_number

p_get_values (prc_records OUT sys_refcursor) - 此过程必须从my_table中选择值，其中id_number = pn_id_number（注意：用于插入值的相同id号，现在用于设置插入的值。）

我已声明包级别变量并指定为ln_id_number = pn_id_number。

现在使用这个＆＃39; ln_id_number＆＃39;在第二个过程中，使用dbms_putput.putline（ln_id_number）检查ln_id_number的值是什么

请帮我这样做，

程序如下

CREATE OR REPLACE PACKAGE BODY pck_exit_info
IS
  ln_id_number po010.polref%TYPE;

  PROCEDURE p_set_values(pn_id_number IN number
                        ,pv_exit_option IN  VARCHAR2)
  IS
    ln_system_date cs340.sysdte%TYPE;
    lv_audaplcde   package_audits.audit_application_code%TYPE;
    ln_audstfno    package_audits.audit_staff_number%TYPE;
    ln_audupdid    NUMBER;
    lv_exit_option VARCHAR2(1);
  BEGIN
    ln_system_date    := pck_system_context.f_get_system_date;
    ln_id_number      := pn_id_number;
    dbms_output.put_line(ln_id_number);

    SELECT AUDUPDID_SEQ.NEXTVAL INTO ln_audupdid FROM DUAL;

    IF pv_exit_option = 'LE' THEN
      lv_exit_option := 'L';
    ELSE
      lv_exit_option := 'S';
    END IF;

    SELECT audit_application_code,audit_staff_number
      INTO lv_audaplcde,ln_audstfno
      FROM package_audits
      WHERE process = 'PCK_LEAVERS'
        AND subprocess ='DEFAULT';

    INSERT INTO my_table
      VALUES(pn_id_number
             ,ln_system_date
             ,lv_exit_option
             ,ln_audupdid
             ,ln_system_date
             ,lv_audaplcde
             ,ln_audstfno);
  END set_employer_exit_info;

  PROCEDURE p_get_values(prc_records OUT SYS_REFCURSOR) IS
  BEGIN
    /*dbms_output.put_line('ID inside get employer');
    dbms_output.put_line(ln_id_number);*/

    OPEN prc_records FOR 
      SELECT *
      FROM   my_table
      WHERE  polref = ln_id_number;
     -- CLOSE  prc_policy;
  END get_employer_exit_info;
END pck_exit_info;
