textTable
中的某些行在EN
中具有语言1
的对应行,例如ID 2
,而其他行则没有,例如ID SELECT
要求您编写连接两个表的id | value1 | value2 | text
---| ------ | ------ | ------
1 | A | 11 | Foobar
3 | C | 13 | bar
语句,以便仅选择具有英文文本的值,即应为结果:
MongoClient.connect(local, {useNewUrlParser: true, useUnifiedTopology: true}, function(err, db) {
if (err) {
console.log(err)
}
else {
console.log('Connected to MongoDB...')
//Read in data from jsonfiles and store each file's contents into the database : This is where the functions are being called... within a successful connect to the MongoDB
insertJSON(db, jsonfiles, 'requests', jsonfilesSource)
insertJSON(db, issuedfiles, 'issuedLicenses', isssuedfilesSource)
insertLicenses(db)
}
db.close()
})
可以用对SQL的基本理解来回答问题,尤其是。加入,不需要特定的ABAP专业知识。
