存储过程的简单例子

 1、 带变量的存储过程

create or replace procedure test1 as

zm_sum number:=0;

cou number:=0;

begin

        select  zm.zgbm_xx into zm_sum from zgbm zm where zm.jgsy_xx=’xx’

        select count(*) into cou from jgsy_xx  d where d.xx=’xx’

        update zgbm zb set zb.xx= cou where zb.jgsy_xx=zm_sum

 end;

 

  2、不带变量的存储过程

create or replace procedure test1 as

begin

update zgbm zb set zb.xx=(select count(*) from jgsy_xx d where d.xx=’xx’)where zb.jgsy_xx=’xx’

 

end;
