PL/SQL带参数的过程

PL/SQL带参数的过程小例子：

in 参数：读入参数，主程序向过程传递参数值；

out参数：读出参数，过程向主程序传递参数值；

in out参数：双向参数．主程序与过程双向交流数据；

sql 代码

Set  serveroutput on
create or replace procedure scott.tempprocedure(
   tempdeptno in scott.dept.deptno%type,
   tempdname out scott.dept.dname%type,
   temploc in out scott.dept.loc%type)as
   loc1   scott.dept.loc%type;
   dname1 scott.dept.dname%type;
begin
   select loc  into loc1
   from  scott.dept
   where  deptno=tempdeptno;
   select dname  into dname1
   from  scott.dept
   where  deptno=tempdeptno;
   temploc:='地址:'||loc1;
   tempdname:='姓名'||dname1;
end;

主程序调用代码：

sql 代码

set serveroutput on
declare
   myno  scott.dept.deptno%type;
   mydname  scott.dept.dname%type;
   myloc  scott.dept.loc%type;
begin
  myno:=10;
  mydname:='崔映辉';
  myloc:='上海信息产业集团';
  scott.tempprocedure(myno,mydname,myloc);
  dbms_output.put_line(myno);
  dbms_output.put_line(mydname);
  dbms_output.put_line(myloc);
end;
