在sqlite3没有这样的列错误

Question

我试图插入值到我的表，但得到一个没有这样的列错误。我在寻找，看到在大多数情况下，这是因为他们错过了引号，但我似乎拥有它们。任何人都可以将我指向正确的方向吗？

CREATE TABLE students (
id INTEGER PRIMARY KEY, 
first_name VARCHAR(255), 
last_name VARCHAR(255), 
grade INT, 
passing BOOLEAN, 
teacher_id INT, 
FOREIGN KEY (teacher_id) REFERENCES teachers(id) 
); 

INSERT INTO students (first_name, last_name, grade, passing, teacher_id) 
VALUES (‘Ted’, ‘Mosby’, 84, true, 2); 

Error: no such column: ‘Ted’

Answer 1

使用'不’和1代替true：

SQLite does not have a separate Boolean storage class. Instead, Boolean values are stored as integers 0 (false) and 1 (true).

INSERT INTO students (first_name, last_name, grade, passing, teacher_id) 
VALUES ('Ted', 'Mosby', 84, 1, 2);
