DB2创建sequence

1、创建sequence

 CREATE sequence my_seq AS INTEGER START WITH 628 increment BY

2、获取sequence的下一个

values nextval for my_seq (my_seq是sequence名称)

3、在sql中使用sequence的下一个值

insert into table_name(id) values(nextval for my_seq )

 

创建SEQUENCE ：

 CREATE   SEQUENCE  NAME_XXX_SEQ   AS   INT  START  WITH  1000 INCREMENT  BY  1 MINVALUE 1
        NO  MAXVALUE  NO  CYCLE  NO  CACHE  ORDER ;

 查询SEQUENCE ：

 SELECT  NEXTVAL  FOR  NAME_XXX_SEQ  FROM  SYSIBM.SYSDUMMY1;
