Question

我很难将简单的数据输入到postgres表中。

这是表格：

user=# \d main_attribute_types;

   Column   |         Type          |                             Modifiers                             
------------+-----------------------+-------------------------------------------------------------------
 id         | integer               | not null default nextval('main_attribute_types_id_seq'::regclass)
 name       | character varying(16) | not null
 field_name | character varying(16) | not null
Indexes:
    "main_attribute_types_pkey" PRIMARY KEY, btree (id)
Referenced by:
    TABLE "main_additional_attributes" CONSTRAINT "main_addi_attribute_type_id_1cb89d3d_fk_main_attribute_types_id" FOREIGN KEY (attribute_type_id) REFERENCES main_attribute_types(id) DEFERRABLE INITIALLY DEFERRED

我试过的命令：

INSERT INTO main_attribute_types (NULL, "Integer", "IntegerField");
INSERT INTO main_attribute_types (1, "Integer", "IntegerField);
INSERT INTO main_attribute_types (id, name, field_name) VALUES (NULL, "Integer", "IntegerField");
INSERT INTO main_attribute_types (name, field_name) VALUES ("Integer", "IntegerField");

每次我收到错误：

ERROR:  column "Integer" does not exist
LINE 1: INSERT INTO main_attribute_types VALUES (1, "Integer", "Inte...
                                                    ^

在官方文档中如何做到这一点： https://www.postgresql.org/docs/9.0/static/dml-insert.html

我的Postgres版本是9.3.13

我完全不知道为什么它不起作用。

尝试

INSERT INTO main_attribute_types (name, field_name) VALUES ('Integer', 'IntegerField');

请记住，not null为每列定义not null。
