Question

我使用schema.sql文件成功创建了一个数据库：

CREATE DATABASE movie_db;

\c movie_db

DROP TABLE movies;

CREATE TABLE movies (
  id BIGSERIAL PRIMARY KEY,
  title VARCHAR(255),
  year integer,
  description VARCHAR(255),
  posterUrl VARCHAR(255),
  screenshotUrl VARCHAR(255)
);

但是当我尝试连接seed.sql文件时，它告诉我ERROR: column "After the death of his father, T'Challa returns home to..." does not exist：

\c movie_db

INSERT INTO movies (title, year, description, posterUrl, screenshotUrl)
VALUES ('Black Panther', 2018, "After the death of his father, T'Challa returns home to...", 'https://ia.media-imdb.com/images/M/MV5BMTg1MTY2MjYzNV5BMl5BanBnXkFtZTgwMTc4NTMwNDI@._V1_UX182_CR0,0,182,268_AL_.jpg', 'http://cdn.wegotthiscovered.com/wp-content/uploads/2017/10/black-panther-movie-image-9.jpg');

我还能够成功插入另一部电影，这部电影在结构上与Black Panther信息相同。

起初我觉得'在T'Challa有一个问题，但当我删除它时，我仍然无法连接。这可能是非常明显的事情，但它一直在困扰我，所以我想我会问听众。

尝试用单引号括起来：

INSERT INTO movies (title, year, description, posterUrl, screenshotUrl)
    VALUES ('Black Panther', 2018, 'After the death of his father, T''Challa returns home to...', 'https://ia.media-imdb.com/images/M/MV5BMTg1MTY2MjYzNV5BMl5BanBnXkFtZTgwMTc4NTMwNDI@._V1_UX182_CR0,0,182,268_AL_.jpg', 'http://cdn.wegotthiscovered.com/wp-content/uploads/2017/10/black-panther-movie-image-9.jpg');

要在SQL中转义单引号，请在一行中使用两个单引号。
