PostgreSQL創建主鍵自增序列並運用到SQL中

創建自增長序列（可以用SQL創建也可以用工具Navicat）

SQL創建序列（Sequences）（注意序列名用小寫，不然會提示不存在）

CREATE SEQUENCE "public"."process_time_seq" 
INCREMENT 1
MINVALUE  1
MAXVALUE 999999999
START 1
CACHE 1;

SELECT setval('"public"."process_time_seq"', 1, false);

ALTER SEQUENCE "public"."process_time_seq" OWNER TO "postgres";

Navicat創建序列（Sequences）：

 

-- 查詢序列：

SELECT nextval('process_time_seq');

--爲主鍵設置Sequences：

alter table "public"."MACHINE_PROCESS_TIME" alter column "ID" set default nextval('process_time_seq');

--放入XML中

insert into "MACHINE_PROCESS_TIME" (
	"ID",
	"FACTORY_ID",
	"WORKSHOP_ID",
	"LINE_ID",
	"STATION_ID",
	"PROCESS_TIME",
	"PROCESS_DATE",
	"CREATE_DATE")values(
	nextval('process_time_seq'),
	#{factoryId,jdbcType=INTEGER},
	#{workshopId,jdbcType=INTEGER},
	#{lineId,jdbcType=INTEGER},
	#{stationId,jdbcType=VARCHAR},
	#{processTime,jdbcType=FLOAT},
	#{processDate,jdbcType=DATE},
	now())
