How to update table's value using Oracle stored procedure

#Step 1 :Sample Table Stu_Info.

SQL> SELECT * from Stu_Info;

STUID	NAME	CITY	AMOUNT
1000	RAM	NEW DELHI	1000
1001	SACHIN	MUMBAI	2000
1002	SMITH	NEW YORK	3000
1003	CHENG	BEIJING	4000

Note : STUID is primary key in this table.

#Step 2 : Create Procedure p_updateStuInfo to update table's value.

SQL> CREATE OR REPLACE PROCEDURE p_updateStuInfo

         2 (p_stuid  IN number,

         3   p_name  IN VARCHAR2,

         4   p_city  IN VARCHAR2,

         5   p_amount IN NUMBER)

         6  IS

         7  BEGIN

         8     UPDATE  Stu_info SET
                  name = p_name,
                  city = p_city,
                  amount =p_amount  where stuid=p_stuid;

         9  END;

        10  /

Step 3 : Execute Procedure multiple times with different values.
Once you created procedure successfully, you can use multiple times passing simply parameters values.
Update #1 : Update City.

SQL> EXEC p_updateStuInfo(1000,'RAM','BANGALORE',1000);

Update #2 : Update Salary

SQL> EXEC p_updateStuInfo(1001,'SACHIN','MUMBAI',3000);
Update #3 : Update name,city and salary.
