【PostgreSQL】------ pg sql先判断是否存在表在创建表结构--实例代码

// if not exists 不存在
CREATE TABLE if not exists "public"."DCS_YZYHK_CARD" (
  "ID" varchar(50) COLLATE "pg_catalog"."default" NOT NULL,
  "ORG_ID" varchar(50) COLLATE "pg_catalog"."default",
  "ORG_NAME" varchar(100) COLLATE "pg_catalog"."default",

  "CREATER" varchar(255) COLLATE "pg_catalog"."default",
  "CREATETIME" date,

)
