pgsql 工具

--查看数据库中有哪些序列
--r =普通表， i =索引，S =序列，v =视图，m =物化视图， c =复合类型，t = TOAST表，f =外部表
select *  from pg_class where relkind='S' 

CREATE SEQUENCE tt_id_seq 
    START WITH 1 
    INCREMENT BY 1 
    MINVALUE 1
    MAXVALUE 2147483647
    CACHE 1; 
ALTER TABLE public.tt_id_seq OWNER TO postgres; 

我这边需要几个操作，一个就是查看序列号
select * from P5EMPROLE_SEQ;
P5EMPROLE_SEQ 是序列号名称
更改序列号开始数字
ALTER SEQUENCE P5EMPROLE_SEQ RESTART WITH 105;
P5EMPROLE_SEQ 是序列号名称

 

将序列绑定到表
ALTER SEQUENCE tt_id_seq OWNED BY tt.id; 
ALTER table tt  ALTER column id set default nextval('tt_id_seq'); 
SELECT pg_catalog.setval('tt_id_seq', 1, false);
