我正尝试创建一个POST路由，如下所示。我的时间表表上有一个Employee表，上面设置了FOREIGN KEY约束。当我尝试使用数据库浏览器插入不存在的员工的时间表时，我得到了由约束触发的正确错误。但是，当我运行下面的代码时，它将忽略此约束并插入记录。我是否对此设置不正确，或者在这种情况下这不是有效的约束条件？
timesheetRouter.post("/", getParams, (req, res, next) => {
const tsData = req.body.timesheet;
console.log("ID", req.empID);
db.run(`insert into Timesheet (hours, rate, date, employee_id)
values ($hours, $rate, $date, $emp);`, {
$hours: tsData.hours,
$rate: tsData.rate,
$date: tsData.date,
$emp: req.empID
}, function(err) {
if (err) {
return res.status(404).send(err);
} else {
db.get("select * from Timesheet where id = $id", {$id: this.lastID},
(err, row) => {
return res.status(201).send({timesheet: row});
});
}
});
});
表创建代码：
db.serialize(() => {
db.run("DROP TABLE IF EXISTS Timesheet", err => {
if (err) {
throw new Error(err);
}
});
db.run(`create table Timesheet (id integer PRIMARY KEY,
hours integer NOT NULL,
rate integer NOT NULL,
date integer NOT NULL,
employee_id integer NOT NULL, FOREIGN KEY (employee_id) REFERENCES Employee (id))`,
err => {
if (err) {
throw new Error(err);
}
});
});
注意：getParams是用于确定empID值的函数。

当前，在SQLite 3.25.2 foreign key constraints are disabled by default版中。您需要通过以下方式打开它们

或者，就您而言
sqlite> PRAGMA foreign_keys = ON;
我认为。
它基于每个连接工作，DB Browser可能会在启动时自动设置它，这就是在这种情况下它触发错误的原因。
