pgsql 工具

--查看數據庫中有哪些序列
--r =普通表， i =索引，S =序列，v =視圖，m =物化視圖， c =複合類型，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; 

我這邊需要幾個操作，一個就是查看序列號
select * from P5EMPROLE_SEQ;
P5EMPROLE_SEQ 是序列號名稱
更改序列號開始數字
ALTER SEQUENCE P5EMPROLE_SEQ RESTART WITH 105;
P5EMPROLE_SEQ 是序列號名稱

 

將序列綁定到表
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);
