Postgres错误更新列数据

Question

尝试在表上运行更新脚本，但出现错误：

错误：列“ok”不存在 第 2 行：设置 first_name="ok"、last_name="pk"、email="ooo"、phone="...

CREATE TABLE employee (
   employee_id      SERIAL PRIMARY KEY,
   first_name       varchar(255)                NOT NULL,
   last_name        varchar(255)                NOT NULL,
   email            varchar(255)                NOT NULL,
   phone            varchar(255)
);


INSERT INTO employee(
            first_name, last_name, email, phone)
    VALUES ('Kyle', 'Belanger', 'kbelanger@ok.com', '(240) 298-4664');


UPDATE "employee"
   SET first_name="ok", last_name="pk", email="ooo", phone="000"
 WHERE employee_id = 1;

Answer 1

表名不用双引号"employee"，列值用单引号

UPDATE employee   
   SET first_name='ok', last_name='pk', email='ooo', phone='000'
 WHERE employee_id = 1;

See Working Example

Answer 2

试试下面的sql：

 UPDATE employee
   SET first_name='ok', last_name='pk', email='ooo', phone='000'
 WHERE employee_id = 1;

表名用双引号括起来，这是不允许的。
