pgAdmin - 尝试创建外键时“引用”不提供任何选项

Question

我有三个表：ModelingAgency.clients，ModelingAgency.models，ModelingAgency.Bookings。所有三个表都有一个名为id的主键列。

表bookings有两列引用clients和models。在pgAdmin中，当我尝试在bookings中创建外键到clients或models时，我会看到以下屏幕：

我在这里俯瞰什么？我是PostgreSQL的新手（这是我的第一个使用PostgreSQL的测试项目 - 我一直使用MySQL，偶尔使用SQL Server）所以它可能是显而易见的（我只是看不到它）。

编辑：根据要求，这是DDL：

-- Table: "ModelingAgency.bookings"

-- DROP TABLE "ModelingAgency.bookings";

CREATE TABLE "ModelingAgency.bookings"
(
  id integer NOT NULL DEFAULT nextval('"ModelingAgency.Bookings_id_seq"'::regclass),
  "clientId" integer NOT NULL,
  "modelId" integer NOT NULL,
  "time" timestamp with time zone NOT NULL DEFAULT now(),
  "location" character varying(100) NOT NULL DEFAULT 'No Location Selected'::character varying,
  CONSTRAINT "bookingId" PRIMARY KEY (id)
)
WITH (
  OIDS=FALSE
);
ALTER TABLE "ModelingAgency.bookings" OWNER TO "MyBatisTutorial";


-- Table: "ModelingAgency.clients"

-- DROP TABLE "ModelingAgency.clients";

CREATE TABLE "ModelingAgency.clients"
(
  id integer NOT NULL DEFAULT nextval('"ModelAgency.clients_id_seq"'::regclass),
  "name" character varying(45) NOT NULL,
  CONSTRAINT "clientId" PRIMARY KEY (id)
)
WITH (
  OIDS=FALSE
);
ALTER TABLE "ModelingAgency.clients" OWNER TO "MyBatisTutorial";


-- Table: "ModelingAgency.models"

-- DROP TABLE "ModelingAgency.models";

CREATE TABLE "ModelingAgency.models"
(
  id serial NOT NULL,
  "name" character varying(45) NOT NULL,
  CONSTRAINT "modelId" PRIMARY KEY (id)
)
WITH (
  OIDS=FALSE
);
ALTER TABLE "ModelingAgency.models" OWNER TO "MyBatisTutorial";

查看您发布的DDL代码，我发现您的表名称编写错误（导致您的问题与pgAdmin一起）：

"ModelingAgency.bookings"

格式应为"schema"."tableName"：

"ModelingAgency"."bookings"

之后，对象浏览器看起来像这样（可能需要先使用pgAdmin或CREATE SCHEMA SQL语句创建模式）：

这是工作的DDL代码（我省略了OIDS和OWNER TO之类的内容，但这与您的情况无关，BTW OIDS默认为false）：

DROP TABLE IF EXISTS  "ModelingAgency"."bookings";
CREATE TABLE "ModelingAgency"."bookings"
(
    id serial,
    "clientId" integer NOT NULL,
    "modelId" integer NOT NULL,
    "time" timestamp with time zone NOT NULL DEFAULT now(),
    "location" character varying(100) NOT NULL
        DEFAULT 'No Location Selected'::character varying,
    CONSTRAINT "bookingId" PRIMARY KEY (id)
);

DROP TABLE IF EXISTS "ModelingAgency"."clients";
CREATE TABLE "ModelingAgency"."clients"
(
    id serial,
    "name" character varying(45) NOT NULL,
    CONSTRAINT "clientId" PRIMARY KEY (id)
);

DROP TABLE IF EXISTS "ModelingAgency"."models";
CREATE TABLE "ModelingAgency"."models"
(
    id serial NOT NULL,
    "name" character varying(45) NOT NULL,
    CONSTRAINT "modelId" PRIMARY KEY (id)
)
