[英]How to move MongoDB document fields to an array of objects?
給定類似於以下文檔的文檔集合
{
"_id": {
"$oid": "60582f08bf1d636f4b762ebc"
}
"experience": [{
"title": "Senior Customer Success Account Manager",
"company": "Microsoft",
"tenure": 8
}, {
"title": "Senior Service Delivery Manager",
"company": "Microsoft",
"tenure": 34
}],
"company3": "Oracle",
"tenure3": 10,
"title3": "Senior Customer Success Manager - EMEA |Oracle Marketing Cloud"
}
我將如何編寫 updateMany 或其他 shell 命令以將體驗數組中的 company3、tenure3 和 title3 作為新的 object {company: <company3 value>, title: <title3 value>, tenure: <tenure3 value>}
?
好像您正在尋找此聚合更新:
db.collection.update({},
[
{
$set: {
experience: {
$concatArrays: [
"$experience",
[
{
company: "$company3",
title: "$title3",
tenure: "$tenure3"
}
]
]
}
}
},
{
$unset: "company3"
},
{
$unset: "tenure3"
},
{
$unset: "title3"
}
],
{
multi: true
})
