oracle Dbeaver存储过程语法详解

可视化工具 Dbeaver

基本语法

增

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

删

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

call delStudent();

DROP  procedure delStudent
SELECT * FROM student

改

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

springboot中使用

一个student表，一个teacher表

有这样一个业务，删除教师，删除其所有学生

CREATE OR REPLACE  PROCEDURE  delTeacher(myTID IN VARCHAR2)
IS
BEGIN
	DELETE FROM teacher WHERE TID=myTID;
END delTeacher;

CREATE OR REPLACE  PROCEDURE  delStudentOfTeacher(myTID IN VARCHAR2)
IS
BEGIN
	DELETE FROM student WHERE TID=myTID;
END delStudentOfTeacher;

<delete id="teacherDelete" parameterType="int">
        {call delTeacher(#{arg0})}
</delete>

<delete id="studentOfTeacherDelete" >
        {call delStudentOfTeacher(#{arg0}) }
</delete>

测试

@Test
    void contextLoads() {
        teacherService.deleteTeacher(2);
    }

增

CREATE OR REPLACE  PROCEDURE  addTeacher(myTID IN varchar2,myTNAME IN varchar2,myAGE IN varchar2)
IS
BEGIN
	INSERT INTO teacher values(myTID,myTNAME,myAGE);
END addTeacher;

<insert id="teacherAdd">
        call addTeacher(#{arg0},#{arg1},#{arg2})
</insert>

改

CREATE OR REPLACE  PROCEDURE  updateTeacher(myTNAME IN varchar2,myAGE IN varchar2,myTID IN varchar2)
IS
BEGIN
	UPDATE   teacher SET TNAME=myTNAME,AGE=myAGE WHERE TID=myTID;
END updateTeacher;

<update id="teacherUpdate" >
        call updateTeacher(#{arg0},#{arg1},#{arg2});
</update>

学生增删改

增

CREATE OR REPLACE  PROCEDURE  addStudent(myID IN varchar2,myTID IN varchar2,mySID IN varchar2,mySNAME IN varchar2,myAGE IN number,mySEX IN varchar2)
IS
BEGIN
	INSERT INTO student values(myID,myTID,mySID,mySNAME,myAGE,mySEX);
END addStudent;

<insert id="studentAdd" >
        call addStudent(#{arg0},#{arg2},#{arg1},#{arg3},#{arg4},#{arg5})
</insert>

删

CREATE OR REPLACE  PROCEDURE  delStudent(mySID IN varchar2)
IS
BEGIN
	DELETE FROM student WHERE SID=mySID;
END delStudent;

<delete id="studentDelete" >
        call delStudent(#{arg0})
</delete>

改

CREATE OR REPLACE  PROCEDURE  updateStudent(mySID IN varchar2,mySNAME IN varchar2,myAGE IN NUMBER,mySEX IN varchar2)
IS
BEGIN
	UPDATE   student SET  SNAME=mySNAME,AGE=myAGE,SEX=mySEX WHERE SID=mySID;
END updateStudent;
