插入命令 :: 错误:列“值"不存在 [英] INSERT COMMAND :: ERROR: column "value" does not exist

问题描述

我正在使用 postgresql 并且我正在尝试将数据插入表 users.当我使用

INSERT INTO users(user_name, name, password,email) VALUES ("user2","first last","password1", "[e-mail]" );

我收到以下错误:

错误:user2"列不存在

这是桌子的样子.

表public.users"专栏 |类型 |修饰符用户名 |字符变化(50) |姓名 |字符变化(50) |密码 |字符变化(50) |电子邮件 |字符变化(100) |用户 ID |整数 |not null default nextval('users_user_id_seq'::regclass)索引:"users_pkey" PRIMARY KEY, btree (user_id)

我可以插入一行，但现在不起作用.

解决方案

字符常量需要单引号.

使用:INSERT INTO users(user_name, name, password,email) VALUES ('user2','first last','password1', '[e-mail]');

参见手册:postgresql.org/docs/current/static/...

I am using postgresql and I am trying to insert data into a table users. When I do that using

INSERT INTO users(user_name, name, password,email) VALUES ("user2","first last","password1", "[e-mail]" );

I get the following error:

ERROR:  column "user2" does not exist

This is how the table looks like.

Table "public.users"
  Column   |       Type    |  Modifiers                        
 user_name | character varying(50)  | 
 name      | character varying(50)  | 
 password  | character varying(50)  | 
 email     | character varying(100) | 
 user_id   | integer                | not null default nextval('users_user_id_seq'::regclass)
Indexes:
    "users_pkey" PRIMARY KEY, btree (user_id)

I was able to insert a row, but it is not working now.

解决方案

Character constants need single quotes.

Use: INSERT INTO users(user_name, name, password,email) VALUES ('user2','first last','password1', '[e-mail]' );

See the manual: postgresql.org/docs/current/static/…
