我想执行以下sql代码。
--1
CREATE TABLE User_Type(
User_Type_ID Integer NOT NULL PRIMARY KEY,
User_Type_Name Char(20 ) NOT NULL
);
CREATE SEQUENCE User_Type_seq;
CREATE TRIGGER User_Type_ID_trg
BEFORE INSERT ON User_Type
FOR EACH ROW
BEGIN
SELECT User_Type_seq.NEXTVAL INTO :new.User_Type_ID
FROM DUAL;
END;
/
当我手动写入sql developer时,它可以工作。但我需要这样的很多块。所以,我用notepad ++编辑了那些并再次复制/粘贴到sql developer。这次;表和序列已创建,但它给出了关于触发器代码的错误(我已经从select_user_errors中选择了这个例程)
PLS-00103:遇到符号"文件结束"当期待以下之一时:错误103 ;
以下是完整的代码,但不起作用。创建表和序列代码是有效的,但触发代码不是。
--1
CREATE TABLE User_Type(
User_Type_ID Integer NOT NULL PRIMARY KEY,
User_Type_Name Char(20 ) NOT NULL
);
CREATE SEQUENCE User_Type_seq;
CREATE TRIGGER User_Type_ID_trg
BEFORE INSERT ON User_Type
FOR EACH ROW
BEGIN
SELECT User_Type_seq.NEXTVAL INTO :new.User_Type_ID
FROM DUAL;
END;
/
--2
CREATE TABLE Users(
User_ID Integer NOT NULL PRIMARY KEY,
User_Password Char(8 ) NOT NULL,
User_Name Char(20 ) NOT NULL,
User_Type_ID Integer NOT NULL
);
CREATE SEQUENCE Users_seq;
CREATE TRIGGER User_ID_trg
BEFORE INSERT ON Users
FOR EACH ROW
BEGIN
SELECT Users_seq.NEXTVAL INTO :new.User_ID
FROM DUAL;
END;
/
--3
CREATE TABLE Admin(
Admin_ID Integer NOT NULL PRIMARY KEY,
E_mail Char(20 ) NOT NULL,
Phone_Number Char(20 ) NOT NULL,
User_ID Integer NOT NULL
);
CREATE SEQUENCE Admin_seq;
CREATE TRIGGER Admin_ID_trg
BEFORE INSERT ON Admin
FOR EACH ROW
BEGIN
SELECT Admin_seq.NEXTVAL INTO :new.Admin_ID
FROM DUAL;
END;
/
--4
CREATE TABLE City(
City_ID Integer NOT NULL PRIMARY KEY,
City_Name Char(20 ) NOT NULL
);
CREATE SEQUENCE City_seq;
CREATE TRIGGER City_ID_trg
BEFORE INSERT ON City
FOR EACH ROW
BEGIN
SELECT City_seq.NEXTVAL INTO :new.City_ID
FROM DUAL;
/
我搜索了类似的问题,但没有回答解决我的问题。
对不起英语,谢谢...

你在最后一次触发中错过END;
:
CREATE TRIGGER City_ID_trg
BEFORE INSERT ON City
FOR EACH ROW
BEGIN
SELECT City_seq.NEXTVAL INTO :new.City_ID
FROM DUAL;
END;
/
其他所有内容is already created and compiled successfully。
顺便说一句,从11g开始,您可以直接在PL / SQL中分配序列,而无需从双重中选择:
...
BEGIN
:new.City_ID := City_seq.NEXTVAL;
END;
/

它解决了。不幸的是,一个字母错误我还没有理解为什么,但是:
一定是
create trigger
而不是
CREATE TRIGGER
