Sesuai deskripsi masalah Anda di sini:
For example I want to change the quantity of the item 10 in Invoice 123456789.
Saya baru saja mengubah Quantity
ke 3. Anda dapat melakukan operasi apa pun di sini sesuai keinginan. Anda hanya perlu memperhatikan bagaimana saya menggunakan arrayFilters
di sini.
Coba kueri ini:
db.collection.update(
{"_id" : "12345678"},
{$set:{"Invoices.$[element1].Items.$[element2].Quantity":3}},
{multi:true, arrayFilters:[ {"element1._id": "123456789"},{
"element2.Item": { $eq: 10 }} ]}
)
Kueri di atas berhasil dijalankan dari mongo shell (Mongo 3.6.3). Dan saya melihat hasil ini:
/* 1 */
{
"_id" : "12345678",
"Invoices" : [
{
"_id" : "123456789",
"Currency" : "EUR",
"DueTotalAmountInvoice" : 768.37,
"InvoiceDate" : "2016-01-01 00:00:00.000",
"Items" : [
{
"Item" : 10,
"ProductCode" : "ABC567",
"Quantity" : 3.0
},
{
"Item" : 20,
"ProductCode" : "CDE987",
"Quantity" : 1
}
]
},
{
"_id" : "87654321",
"Currency" : "EUR",
"DueTotalAmountInvoice" : 768.37,
"InvoiceDate" : "2016-01-01 00:00:00.000",
"Items" : [
{
"Item" : 30,
"ProductCode" : "PLO987",
"Quantity" : 1,
"Units" : "KM3"
},
{
"Item" : 40,
"ProductCode" : "PLS567",
"Quantity" : 1,
"DueTotalAmountInvoice" : 768.37
}
]
}
]
}
Apakah itu yang Anda inginkan?
