我对PostgreSQL上的SQL指令有麻烦

Question

我在PostgreSQL上有以下说明：

CREATE TABLE ACTOR(
    ACT_CUIL            NUMERIC(8,0) NOT NULL,
    ACT_NOMBRE      CHARACTER VARYING(25) NOT NULL,
    ACT_APELLIDOPAT     CHARACTER VARYING(25) NOT NULL,
    ACT_APELLIDOMAT     CHARACTER VARYING(25) NOT NULL,
    ACT_NOMARTCO            CHARACTER VARYING(25) NULL,
    ACT_ROL         CHARACTER VARYING(25) NOT NULL,
    PRIMARY KEY             (ACT_CUIL),
    FOREIGN KEY            (ID_ELEN)  REFERENCES ELENCO(ID_ELEN)
);

创建了来自 ACTOR 的主键;但 pgAdmin 编译器告诉我：

NOTICE:  CREATE TABLE / PRIMARY KEY will create implicit index "actor_pkey" for table "actor"
ERROR:  column "id_elen" referenced in foreign key constraint does not exist

********** Error **********
ERROR: column "id_elen" referenced in foreign key constraint does not exist
SQL state: 42703

关于这个我不知道有什么问题。我在 http://www.postgresql.org/docs/8.1/static/ddl-constraints.html 使用官方文档

谢谢问候

Answer 1

这意味着 ELENCO 表中不存在id_elen列。

Answer 2

似乎有一个表格"elenco"，至少在场上 - id_elen。此表是否存在？

否则不允许有外交关系。
