Oracle存储过程创建方式

create or replace package testa is
procedure find(
    pi$param1   in number,  --参数1 数字
    pi$param2   in varchar2,--参数2 字符串
    pi$param3   in date,    --参数3 日期
    --------------------输出参数-----------------------
    po$count           out number, --总条数
    po$result          out  row_types.resultset--结果集
  );
end testa ;

create or replace package body testa is
procedure find(
    pi$param1   in number,  --参数1 数字
    pi$param2   in varchar2,--参数2 字符串
    pi$param3   in date,    --参数3 日期
    --------------------输出参数-----------------------
    po$count           out number, --总条数
    po$result          out row_types.resultset--游标结果集
  )

 -- 此处可以声明变量：在 oracle 存储过程中，使用declare关键字来声明变量。
 -- 变量声明通常放在存储过程的is或as关键字之后，begin关键字之前。声明变量的基本格式为变量名 数据类型 [ := 初始值];
 declare

    v_count number := 0;
    v_1 varchar2(50) :='';
 begin 
 	-- 此处处理业务逻辑
  -- 最后返回结果：
  -- 直接赋值
  po$count := 数量
  -- 通过select  into 赋值
   select count(1) into po$count from xxx;
  -- 通过游标返回数据集合
   open po$result for sql 语句;
