oracleDbeaver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
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
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 in
</delete>
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;
