4、 編寫一個過程。要求:有一個輸入?yún)?shù)和一個輸出參數(shù),過程里面要有自定義異常。從學(xué)生表中(tab_student)中尋找符合指定學(xué)號等于輸入?yún)?shù)的值,然后將找到的學(xué)生的姓名賦予輸出參數(shù),如果沒有符合條件的值則觸發(fā)異常。
Create table tab_student
(sno char(8),
sname varchar2(20),
age integer,
province varchar2(60),
sex char(4))
insert into tab_student values(‘001’,’Zhou’,20,’江蘇徐州’,’男’)
上述表已經(jīng)創(chuàng)建,只需針對此表編寫即可。
