Oracle存储过程模板

1、无参数存储过程

CREATE OR REPLACE PROCEDURE stu_proc AS
    --声明语句段
    v_name VARCHAR2(20);
BEGIN
    --执行语句段
    SELECT o.sname INTO v_name FROM student o WHERE o.id=4;
    dbms_output.put_line(v_name);
EXCEPTION
    --异常处理语句段
    WHEN NO_DATA_FOUND THEN dbms_output.put_line('NO_DATA_FOUND');
END;

2、仅带入参的存储过程

CREATE OR REPLACE PROCEDURE stu_proc(v_id IN student.id%type) AS
    --声明语句段
    v_name varchar2(20);
BEGIN
    --执行语句段
    SELECT o.sname INTO v_name FROM student o where o.id=v_id;
    dbms_output.put_line(v_name);
EXCEPTION
    --异常处理语句段
    WHEN NO_DATA_FOUND THEN dbms_output.put_line('NO_DATA_FOUND');
END;

3、仅带出参的存储过程

CREATE OR REPLACE PROCEDURE stu_proc(v_name OUT student.sname%type) AS
    --声明语句段
BEGIN
    --执行语句段
    SELECT o.sname INTO v_name FROM student o where o.id=1;
    dbms_output.put_line(v_name);
EXCEPTION
    --异常处理语句段
    WHEN NO_DATA_FOUND THEN dbms_output.put_line('NO_DATA_FOUND');
END;

4、带入参和出参的存储过程

--此种存储过程不能直接用call来调用，这种情况的调用将在下面oracle函数调用中说明
CREATE OR REPLACE PROCEDURE stu_proc(v_id IN student.id%type, v_name OUT student.sname%type) AS
    --声明语句段
BEGIN
    --执行语句段
    SELECT o.sname INTO v_name FROM student o where o.id=v_id;
    dbms_output.put_line(v_name);
EXCEPTION
    --异常处理语句段
    WHEN NO_DATA_FOUND THEN dbms_output.put_line('NO_DATA_FOUND');
END;
