来自以下代码：
router.post('/rushee/add', bodyParser.json(), function (req, res, next) {
const Email = req.body.data.Email
const FirstName = req.body.data.FirstName
const LastName = req.body.data.LastName
const SID = req.body.data.sSID
const GradYear = req.body.data.GradYear
const Nationality = req.body.data.Nationality
const Faculty = req.body.data.Faculty
const PhoneNumber = req.body.data.PhoneNumber
const RusheeIDNumber = req.body.data.RusheeIDNumber
const query1 = 'INSERT INTO Student2 (Email, FirstName, LastName) VALUES (:Email, :FirstName, :LastName) ;'
const query2 = 'INSERT INTO Student3 (SID, FirstName, LastName, GradYear, Nationality, Faculty, PhoneNumber) VALUES (:SID, :FirstName, :LastName, :GradYear, :Nationality, :Faculty, :PhoneNumber) ;'
const query3 = 'INSERT INTO Rushee (R_SID, RusheeIDNumber) VALUES (:SID, :RusheeIDNumber) ;'
connection.query(query1,
{
type: connection.QueryTypes.INSERT,
replacements: {
Email: Email,
FirstName: FirstName,
LastName: LastName
}
})
.then(result => {
// result[1] is the number of rows changed
res.send('/rushee')
})
connection.query(query2,
{
type: connection.QueryTypes.INSERT,
replacements: {
SID: SID,
FirstName: FirstName,
LastName: LastName,
GradYear: GradYear,
Nationality: Nationality,
Faculty: Faculty,
PhoneNumber: PhoneNumber
}
})
.then(result => {
// result[1] is the number of rows changed
res.send('/rushee')
})
connection.query(query3,
{
type: connection.QueryTypes.INSERT,
replacements: {
R_SID: SID,
RusheeIDNumber: RusheeIDNumber
}
})
.then(result => {
// result[1] is the number of rows changed
res.send('/rushee')
})
})
I am not sure what we are missing?
