Question

使用序列和触发器创建标识列。但由于最后缺少半冒号而无法运行脚本

create table slide1 ( id number(10),
subject varchar2(25),constraint pk_id PRIMARY KEY(id)
);

Create sequence  slide1_sequence start with 1
increment by 1
minvalue 1
maxvalue 10000;

create sequence id_seq;

CREATE OR REPLACE TRIGGER slide1_trigger 
BEFORE INSERT ON slide1
FOR EACH ROw

BEGIN
  SELECT slide1_seq.NEXTVAL
  INTO :new.id
  FROM   dual
close slide1;
END;

    SQL> Create sequence  slide1_sequence start with 1 increment by 1 minvalue 1 maxvalue 10000;
    Sequence created

SQL> create sequence id_seq;
Sequence created

    SQL> CREATE OR REPLACE TRIGGER slide1_trigger
      2  BEFORE INSERT ON slide1
      3  FOR EACH ROw
      4  
      5  BEGIN
      6    SELECT slide1_sequence.NEXTVAL
      7    INTO :new.id
      8    FROM   dual;
      9  END;
     10

    Trigger created
