(1)set serveroutput on

实现plsql developer 打印输出

(2)如何查看存储过程，存储函数，触发器的内容

查 user_sources表

eg：查询GET_DEPT_SUMSAL这个存储函数的内容

SQL> desc user_source

名称 是否为空? 类型

----------------------------------------- -------- ----------------------------

NAME VARCHAR2(30)

TYPE VARCHAR2(12)

LINE NUMBER

TEXT VARCHAR2(4000)

SQL> select text from user_source where name = 'GET_DEPT_SUMSAL';

TEXT

--------------------------------------------------------------------------------

function get_dept_sumsal(v_deptno number)

return number

is

sumsal number(10):=0;

cursor emp_sal_cursor is select sal from emp where deptno =v_deptno;

begin

for c in emp_sal_cursor loop

sumsal := c.sal + sumsal;

end loop;

return sumsal;

end;

(3) 注意 'GET_DEPT_SUMSAL'; 这里大写加引号引起来
