Sql命令在表中选择多个选项

标签： sql postgresql pgadmin-4 postgresql-10

我正在使用地理处理软件中的数据库并遇到了一些问题。有必要在这个数据库中创建一个额外的层，我也决定尝试创建它。

使用pgAdmin 4软件，PostgreSQL 10.1和postgis 10.我在下面提交了我在数据库中创建此图层的行。

我设法创建了图层，一切正常，字段显示，每列的选项都出现了，但问题是：我需要administracao和classeativecon列来接受多个元素，而不仅仅是一个。例如，在admin层中，我想放置代码2和3，但只接受一个。

我认为这很简单，但由于我的知识几乎为零，我无法做到。我希望你能帮助我。

CREATE INDEX edf_edificacao_pavimento_a_gist
    ON ge.edf_edificacao_pavimento_a USING gist (geom);

阵列而不是标量类型将是一个简单，肮脏的解决方案。但由于你有FK限制，这不是一个选择。

如果您始终要求完全两个值administracao值，则只需添加两列administracao1和administracao2。对于不同的数量，创建1-n表。像：

CREATE TABLE ge.edf_edificacao_pavimento_administracao (
  edf_id        int NOT NULL REFERENCES ge.edf_edificacao_pavimento_a (id) ON UPDATE CASCADE ON DELETE CASCADE
, administracao smallint NOT NULL REFERENCES dominios.administracao (code)
, PRIMARY KEY (edf_id, administracao)
, CONSTRAINT edf_edificacao_a_administracao_check CHECK (administracao = ANY ('{2,3,4,5,6,95,97}'::int2[]))
);

允许任意数量的元素。但是，执行至少一个值更难。你还不清楚确切的要求。
