oracle错误(二) ORA-01400: 无法将 NULL 插入 ("SL"."TEMP_TEST_TABLE"."ID")的解决方案
之前都是mysql数据库，现在因为项目需要开始接触oracle数据库,新手上路,难免磕磕碰碰,把自己遇到的问题记录下来,方便查询！
一 建表脚本:
DROP TABLE TEMP_TEST_TABLE;
CREATE TABLE TEMP_TEST_TABLE
(
id NUMBER NOT NULL,
author VARCHAR2(200),
publishing VARCHAR2(200),
publish_time TIMESTAMP(6),
word_number VARCHAR2(15),
which_edition VARCHAR2(15),
total_page VARCHAR2(15),
print_time TIMESTAMP(6),
print_number VARCHAR2(15),
isbn VARCHAR2(25),
author_summary VARCHAR2(250),
catalogue VARCHAR2(250)
)
--指定表空间(可以不指定)

initrans 1
maxtrans 255
storage
(

);
-- Add comments to the table

-- Add comments to the columns
comment on column TEMP_TEST_TABLE.id is '图书ID';
comment on column TEMP_TEST_TABLE.author is '图书作者';
comment on column TEMP_TEST_TABLE.publishing is '出版社';

comment on column TEMP_TEST_TABLE.print_number is '印刷次数';
comment on column TEMP_TEST_TABLE.isbn is '版本号';
comment on column TEMP_TEST_TABLE.author_summary is '作者简介';
comment on column TEMP_TEST_TABLE.catalogue is '图书描述';
-- Create/Recreate primary, unique and foreign key constraints

using index

);信息如下:

... 44 more仔细检查了好几遍都没有问题,结果不是代码的问题;是oracle数据库中TEMP_TEST_TABLE表字段ID是自增的,没有创建序列和触发器的缘故;
因此为该表加上序列和触发器,即可
二 创建序列脚本:
-- Create sequence
create sequence TEMP_TEST_TABLE_SEQ
minvalue 1 -- 最小值=1
maxvalue 999999999999999999999999999 -- 指定最大值
-- 或nomaxvalue -- 没有最大值
-- NOCYCLE; -- 不循环
start with 1 -- 从1开始
increment by 1 -- 每次递增1
cache 20;在PLSQL Developer中创建：
--触发器
create or replace trigger TEMP_TEST_TABLE_TRI
before insert on TEMP_TEST_TABLE
REFERENCING OLD AS "OLD" NEW AS "NEW" FOR EACH ROW
begin
SELECT TEMP_TEST_TABLE_SEQ.NEXTVAL INTO :NEW.ID FROM DUAL;
end;
