Oracle存储过程，以逗号分隔字符串传参的处理

Oracle存储过程，经常会遇见传入的参数是逗号分隔。

处理需要3步：

第一步，创建Type类型

第二部，创建函数

第三部，创建存储过程

代码如下：

第一步：

create or replace type varTableType as table
   of nvarchar2(40)

第二步：

create or replace function str2numList123( p_string in varchar2 ) return
          varTableType
           as
           v_str long default p_string || ',';
           v_n number;
           v_data varTableType := varTableType();
           begin
           loop
          v_n := to_number(instr( v_str, ',' ));
          exit when (nvl(v_n,0) = 0);
          v_data.extend;
          v_data( v_data.count ) := ltrim(rtrim(substr(v_str,1,v_n-1)));
          v_str := substr( v_str, v_n+1 );
          end loop;
          return v_data;
          end;

第三步：

CREATE OR REPLACE PROCEDURE PROC_UPDATE_LIUYANG(VIDNUMERIC VARCHAR2,
                                                VMARK      VARCHAR2,

                                                VMODIFYBY  VARCHAR2, verrorint out int) AS
