Postgres 错误更新列数据

Question

尝试运行 table 上的更新脚本，但出现错误：

ERROR: column "ok" does not exist LINE 2: SET 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

不需要将 table 名称用双引号 "employee" 括起来，对列值使用单引号

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

See Working Example

Answer 2

尝试以下 sql:

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

Table 名称用双引号括起来，这是不允许的。
