postgres學習總結

第一個建表語句：

DROP TABLE IF EXISTS "public"."eshop_city";
CREATE TABLE "public"."eshop_city" (
  "id" serial8 NOT NULL PRIMARY KEY,
  "del_flag" int2,
  "create_user" int4,
  "update_user" int4,
  "create_time" timestamp(6) NOT NULL,
  "update_time" timestamp(6)
)
;
COMMENT ON COLUMN "public"."eshop_city"."id" IS '全國城市表主鍵id';
COMMENT ON COLUMN "public"."eshop_city"."del_flag" IS '是否軟刪除：0;否，1:是';
COMMENT ON COLUMN "public"."eshop_city"."create_user" IS '創建用戶id';
COMMENT ON COLUMN "public"."eshop_city"."update_user" IS '更新用戶id';
COMMENT ON COLUMN "public"."eshop_city"."create_time" IS '創建時間';
COMMENT ON COLUMN "public"."eshop_city"."update_time" IS '更新時間';
COMMENT ON TABLE "public"."eshop_city" IS '全國城市表';

查詢表結構
select tablename from pg_tables where schemaname='public'

用navicat12看不到postgre數據庫裏的表
更新navicat12到15就可以了
