创建存储过程示例
CREATE OR REPLACE PROCEDURE P_XT_TEST_ZWL IS TESTVALUE VARCHAR2(500); LS_ERR VARCHAR2(500); --错误日志 BEGIN
SELECT H.SQLXH INTO TESTVALUE FROM CX_CXDY H WHERE ROWNUM < 3; COMMIT; EXCEPTION WHEN OTHERS THEN
LS_ERR := '错误：' || SQLCODE || ': ' || SUBSTR(SQLERRM, 1, 500); dbms_output.put_line(LS_ERR); END;
调用
BEGIN
P_XT_TEST_ZWL;
END;
-- 创建输入参procedure:
drop procedure insert_student
create or replace procedure insert_student
(
user_id Number,user_name varchar2,user_pass varchar2
)
as
begin
insert into student values(user_id,user_name,user_pass);
end insert_student;
begin
insert_student(1,'aaa','bbb');
commit;
end;
创建输出参procedure:
drop procedure proc_test2
create or replace procedure proc_test2
(
invalue out varchar2
)
as
begin
select user_name into invalue from user_info where user_id = 1001;
end proc_test2;
/
declare
parameter varchar2(20);
begin
proc_test2(parameter);
dbms_output.put_line(parameter);
end;
--既有输入，又有输出
create or replace procedure proc_test3
(
invalue in Integer,outvalue out varchar2
)
as
begin
select user_name into outvalue from user_info where user_id = invalue;
end proc_test3;
/
declare
parameter Integer := 1001;
parameter1 varchar2(20);
begin
proc_test3(parameter,parameter1);
dbms_output.put_line(parameter1);
end;
