PostgreSQL 主鍵自動增長

建立主鍵並設置自動增加的辦法好好幾種，這里記錄我測試過的：

 

drop table pro_process;
CREATE TABLE "public"."pro_process" (
"id" SERIAL primary key,  //設置主鍵並自動增長
"county_code" varchar(6) COLLATE "default" NOT NULL,
"county_name" varchar(50) COLLATE "default" NOT NULL,
"creator" varchar(100) COLLATE "default" NOT NULL,
"create_time" date NOT NULL
)
WITH (OIDS=FALSE)
;

ALTER TABLE "public"."pro_process" OWNER TO "postgres";
