我有一个Oracle 11g脚本来创建一个表，一个用序列更新主键的触发器，以及为行插入语句。当我尝试运行整个脚本时，它失败并显示消息：
错误（6,1）：PLS-00103：遇到符号“INSERT”
以下是代码：
CREATE TABLE LOCATION(
LOC_ID INTEGER PRIMARY KEY,
LOC_NAME VARCHAR(255) NOT NULL,
LOC_STREET VARCHAR(255) NOT NULL,
LOC_CITY VARCHAR(127) NOT NULL,
LOC_STATE CHAR(2) NOT NULL CHECK (REGEXP_LIKE (LOC_STATE,'[A-Z][A-Z]')),
LOC_ZIPCODE CHAR(9) CHECK (LOC_ZIPCODE BETWEEN 1 AND 999999999) ,
LOC_AREACODE CHAR(3), CHECK (LOC_AREACODE BETWEEN 1 AND 999),
LOC_PHONE CHAR(7) NOT NULL UNIQUE CHECK (LOC_PHONE BETWEEN 1 AND 9999999)
);
CREATE SEQUENCE LOC_NUM_UPDATE START WITH 100 INCREMENT BY 5;
CREATE OR REPLACE TRIGGER NEW_LOC_NUM
BEFORE INSERT ON LOCATION
FOR EACH ROW
BEGIN
SELECT LOC_NUM_UPDATE.NEXTVAL
INTO :NEW.LOC_ID
FROM DUAL;
END;
INSERT INTO LOCATION VALUES(1,'Stubbs','801 Red River St', 'Austin', 'TX', '78701','512','4808341');
INSERT INTO LOCATION VALUES(1,'Backyard','13801 Bee Cave Pkwy', 'Austin', 'TX', '78738','512','6515033');
INSERT INTO LOCATION VALUES(1,'Emo''s','2015 E Riverside Dr', 'Austin', 'TX', '78741','512','4808341');
INSERT INTO LOCATION VALUES(1,'Mohawk','912 Red River St', 'Austin', 'TX', '78701','512','5670653');
INSERT INTO LOCATION VALUES(1,'Continental','1315 S Congress Ave', 'Austin', 'TX', '78704','512','4412444');
INSERT INTO LOCATION VALUES(1,'Broken Spoke','3201 S Lamar Blvd', 'Austin', 'TX', '78704','512','4426189');
那么，有没有办法'逃避'CREATE TRIGGER活动以在'END;'之后插入值？

Dynamic SQL执行所有DDL语句并使用SET SCAN OFF;命令，因为你使用:NEW;
SET SCAN OFF;
execute immediate 'CREATE TABLE LOCATION(
LOC_ID INTEGER PRIMARY KEY,
LOC_NAME VARCHAR(255) NOT NULL,
LOC_STREET VARCHAR(255) NOT NULL,
LOC_CITY VARCHAR(127) NOT NULL,
LOC_STATE CHAR(2) NOT NULL CHECK (REGEXP_LIKE (LOC_STATE,''[A-Z][A-Z]'')),
LOC_ZIPCODE CHAR(9) CHECK (LOC_ZIPCODE BETWEEN 1 AND 999999999) ,
LOC_AREACODE CHAR(3), CHECK (LOC_AREACODE BETWEEN 1 AND 999),
LOC_PHONE CHAR(7) NOT NULL UNIQUE CHECK (LOC_PHONE BETWEEN 1 AND 9999999)

execute immediate'
CREATE SEQUENCE LOC_NUM_UPDATE START WITH 100 INCREMENT BY 5';
execute immediate'
CREATE OR REPLACE TRIGGER NEW_LOC_NUM
BEFORE INSERT ON LOCATION
FOR EACH ROW
BEGIN
SELECT LOC_NUM_UPDATE.NEXTVAL
INTO :NEW.LOC_ID
FROM DUAL;
END';
end;

这里有很多问题。数据类型，触发后缺少执行命令（例如/），并且当触发器将负责为其分配值时，尝试在更新语句中为loc_id分配值。
我倾向于使用NUMBER(10,0)（使用你的精确度
需要）INTEGER这是可接受的，但不是传统的。
关于VARCHAR数据类型，Oracle希望我们使用
VARCHAR2数据类型。
关于使用CHAR，state，city的固定宽度数据类型
区号和电话号码，你真的想要固定宽度吗？我会使用VARCHAR2。
我在触发器后添加了一个执行命令/，并修改了insert语句以解决触发器活动。
这是您修改的ddl和dml：
CREATE TABLE LOCATION
(
LOC_ID INTEGER PRIMARY KEY,
LOC_NAME VARCHAR(255) NOT NULL,
LOC_STREET VARCHAR(255) NOT NULL,
LOC_CITY VARCHAR(127) NOT NULL,
LOC_STATE CHAR(2) NOT NULL CHECK (REGEXP_LIKE (LOC_STATE,'[A-Z][A-Z]')),
LOC_ZIPCODE CHAR(9) CHECK (LOC_ZIPCODE BETWEEN 1 AND 999999999) ,
LOC_AREACODE CHAR(3),
CHECK (LOC_AREACODE BETWEEN 1 AND 999),
LOC_PHONE CHAR(7) NOT NULL UNIQUE CHECK (LOC_PHONE BETWEEN 1 AND 9999999)
);
CREATE SEQUENCE LOC_NUM_UPDATE START WITH 100 INCREMENT BY 5;
CREATE OR REPLACE TRIGGER NEW_LOC_NUM BEFORE
INSERT ON LOCATION FOR EACH ROW BEGIN
SELECT LOC_NUM_UPDATE.NEXTVAL INTO :NEW.LOC_ID FROM DUAL;
END;
/
INSERT
INTO LOCATION
(
LOC_NAME,
LOC_STREET,
LOC_CITY,
LOC_STATE,
LOC_ZIPCODE,
LOC_AREACODE,
LOC_PHONE
)
VALUES
(
'Stubbs',
'801 Red River St',
'Austin',
'TX',
'78701',
'512',
'4808341'
);
INSERT
INTO LOCATION
(
LOC_NAME,
LOC_STREET,
LOC_CITY,
LOC_STATE,
LOC_ZIPCODE,
LOC_AREACODE,
LOC_PHONE
)
VALUES
(
'Backyard',
'13801 Bee Cave Pkwy',
'Austin',
'TX',
'78738',
'512',
'6515033'
);
这是执行此ddl和dml：
SCOTT@erp> CREATE TABLE LOCATION
2 (
3 LOC_ID INTEGER PRIMARY KEY,
4 LOC_NAME VARCHAR(255) NOT NULL,
5 LOC_STREET VARCHAR(255) NOT NULL,
6 LOC_CITY VARCHAR(127) NOT NULL,
7 LOC_STATE CHAR(2) NOT NULL CHECK (REGEXP_LIKE (LOC_STATE,'[A-Z][A-Z]')),
8 LOC_ZIPCODE CHAR(9) CHECK (LOC_ZIPCODE BETWEEN 1 AND 999999999) ,
9 LOC_AREACODE CHAR(3),
10 CHECK (LOC_AREACODE BETWEEN 1 AND 999),
11 LOC_PHONE CHAR(7) NOT NULL UNIQUE CHECK (LOC_PHONE BETWEEN 1 AND 9999999)
12 );
Table created.
SCOTT@erp> CREATE SEQUENCE LOC_NUM_UPDATE START WITH 100 INCREMENT BY 5;
Sequence created.
SCOTT@erpdev> CREATE OR REPLACE TRIGGER NEW_LOC_NUM BEFORE
2 INSERT ON LOCATION FOR EACH ROW BEGIN
3 SELECT LOC_NUM_UPDATE.NEXTVAL INTO :NEW.LOC_ID FROM DUAL;
4 END;
5 /
Trigger created.
SCOTT@erp> INSERT
2 INTO LOCATION
3 (

12 VALUES
13 (
14 'Stubbs',
15 '801 Red River St',
16 'Austin',
17 'TX',
18 '78701',
19 '512',
20 '4808341'
21 );
1 row created.

我以这种方式更改了你的脚本（只是一些格式化）并且在SQL plus中为我工作（我必须更改第三个插入loc_phone值，因为它有唯一的约束）
CREATE TABLE location(
LOC_ID INTEGER PRIMARY KEY,
LOC_NAME VARCHAR(255) NOT NULL,
LOC_STREET VARCHAR(255) NOT NULL,
LOC_CITY VARCHAR(127) NOT NULL,
LOC_STATE CHAR(2) NOT NULL CHECK (REGEXP_LIKE (LOC_STATE,'[A-Z][A-Z]')),
LOC_ZIPCODE CHAR(9) CHECK (LOC_ZIPCODE BETWEEN 1 AND 999999999) ,
LOC_AREACODE CHAR(3) CHECK (LOC_AREACODE BETWEEN 1 AND 999),
LOC_PHONE CHAR(7) NOT NULL UNIQUE CHECK (LOC_PHONE BETWEEN 1 AND 9999999)
);
CREATE SEQUENCE LOC_NUM_UPDATE START WITH 100 INCREMENT BY 5;
/
CREATE OR REPLACE TRIGGER NEW_LOC_NUM
BEFORE INSERT ON location
FOR EACH ROW
BEGIN
SELECT LOC_NUM_UPDATE.NEXTVAL
INTO :NEW.LOC_ID
FROM DUAL;
END;
