问题：
举个简单例子说明
create or replace procedure procStr(inString in varchar2）
as
begin
select * from book where id in (inString);
end procStr;
我在inString中输入‘21,22’，21,22，‘‘21’，‘22’’
都不行，请教各位大侠如何通过参数，给存储过程的in语句进行赋值
其中inString中id的个数是不定的，多少都有可能
解决办法：
1.
create or replace procedure procStr(inString in varchar2）
as
begin
execute immediate 'select * from book where id in ('||inString||')';
end procStr;
2.
-- 给个例子给你：CREATE OR REPLACE PACKAGE pkg_emp
AS TYPE myrctype IS REF CURSOR;
PROCEDURE Get_empinfo(v_empno IN VARCHAR2, p_rc OUT myrctype);
END pkg_emp;
/CREATE OR REPLACE PACKAGE BODY pkg_emp
AS PROCEDURE Get_empinfo(v_empno IN VARCHAR2, p_rc OUT myrctype)
IS
sqlstr VARCHAR2(4000);
BEGIN
sqlstr := 'SELECT * FROM emp WHERE empno IN ('||v_empno||')';
OPEN p_rc FOR sqlstr;
END Get_empinfo;
END pkg_emp;
/SQL> var v_rc refcursor;SQL> exec pkg_emp.Get_empinfo('7902,7788',:v_rc);
SQL> print v_rc;3.create or replace procedure procStr(inString in varchar2）
as
sys_refcursor resultcur ;
begin
open resultcur for 'select * from book where id in (' || inString || ')';
end procStr;
as
sys_refcursor resultcur ;
begin
open resultcur for 'select * from book where id in (' || inString || ')';
end procStr;
