Create Procedure on MYSQL语法

Question

我大部分时间都在Oracle db上工作，但现在我必须在mysql数据库上创建一个过程。但是，我不知道它的语法。我必须将下面的过程转换为mysql语法。

我应该更改哪些参数？

CREATE OR REPLACE procedure schema.procedure IS
    l_sender              varchar2(200);
    l_recipient           varchar2(1000);
    l_subject             varchar2(100);
    l_msg                   varchar2(32760);  
    l_content_desc    varchar2(32760);
    l_count number := 0;
    l_time number;
    content_desc    varchar2(32760);
    l_body clob;
    counter number:=0;
 begin

l_subject := '';  
l_msg := '';    
l_sender := 'mail1';
l_recipient :=’mail2’;
l_subject   :=  to_char(sysdate-1, 'dd/mm/yyyy')|| '     '||xyzkcqlncqnl ';
l_msg := '';

  FOR r in (
    MY QUERY )

  LOOP
