基本语法

CREATE OR REPLACE  PROCEDURE  addStudent
IS 
BEGIN
	INSERT INTO student values(6,2,5,'小陈',22,0);
END addStudent; 

call addStudent();

DROP  procedure getStudent 
SELECT * FROM student

CREATE OR REPLACE  PROCEDURE  delStudent
IS 
BEGIN
	DELETE FROM student WHERE ID='6';
END delStudent; 

call delStudent();

DROP  procedure delStudent 
SELECT * FROM student

CREATE OR REPLACE  PROCEDURE  updateStudent
IS 
BEGIN
	UPDATE   student SET  AGE=25 WHERE ID='5';
END updateStudent; 

call updateStudent();

DROP  procedure updateStudent 
SELECT * FROM student

单个查询

CREATE OR REPLACE  PROCEDURE  getStudentCount
(studentCount OUT NUMBER)
IS 
BEGIN
	SELECT   count(*) INTO studentCount FROM student;
END getStudentCount; 

DECLARE
studentCount NUMBER(38);
BEGIN
	getStudentCount(studentCount);
dbms_output.put_line(studentCount);
END;

DROP  procedure getStudentCount 
SELECT * FROM student

多行查询

--定义存储过程,返回游标
CREATE OR REPLACE PROCEDURE  getAllStudent(resule OUT sys_refcursor) IS  --返回游标
BEGIN 
	OPEN resule FOR SELECT * FROM student;
END;

--查询存储过程
DECLARE
	cur SYS_REFCURSOR;  --游标
	result_row student%rowtype;  
BEGIN
	getAllStudent(cur);
	LOOP
		FETCH cur INTO result_row ;
		EXIT WHEN cur%notfound;
		dbms_output.put_line('ID: '||result_row.ID||' TID: '||result_row.TID||'SID: '||result_row.SID||' SNAME: '||result_row.SNAME||' AGE: '||result_row.AGE||' SEX: '||result_row.SEX);
	END LOOP;
	CLOSE cur;
END;

DROP  procedure getAllStudent 
SELECT * FROM student
