我在MongoDB中有一组元素数组,如下所示:
{
"_id" : 5,
"quizzes" : [
{
"wk" : 1,
"score" : 10
},
{
"wk" : 2,
"score" : 8
},
{
"wk" : 3,
"score" : 5
}
],
"play" : [
{
"wk" : 2,
"score" : 8
},
{
"wk" : 3,
"score" : 5
}
]
}
我正在尝试在数组中插入新记录(如果不存在),如果该数组中存在记录,则更新该数组记录.下面是我的MongoDB查询.
db.push.update(
{ _id: 5 },
{ $push: { "quizzes": {"wk" : 6.0,"score" : 8.0},"play": {"wk" : 6.0,"score" : 8.0} } }
)
每当我执行此查询时,它会在数组中插入新记录但我想如果记录存在则更新该数组.
我在 MongoDB 中有一组元素，如下所示：
/* 1 */
{
"_id" : ObjectId("58736c7f7d43c305461cdb9b"),
"Name" : "Kevin",
"pb_event" : [
{
"event_type" : "Birthday",
"event_date" : "2014-08-31"
},
{
"event_type" : "Anniversary",
"event_date" : "2014-08-31"
}
]
}
/* 2 */
{
"_id" : ObjectId("58736cfc7d43c305461cdba8"),
"Name" : "Peter",
"pb_event" : [
{
"event_type" : "Birthday",
"event_date" : "2014-08-31"
},
{
"event_type" : "Anniversary",
"event_date" : "2015-03-24"
}
]
}
/* 3 */
{
"_id" : ObjectId("58736cfc7d43c305461cdba9"),
"Name" : "Pole",
"pb_event" : [
{
"event_type" …我有以下类型的文件。
{
"_index": "example1",
"_type": "doc",
"_id": "8036",
"_score": 1,
"_source": {
"user": "kimchy8036",
"postDate": "2009-11-15T13:12:00",
"locations": [
[
72.79887719999999,
21.193036000000003
],
[
-1.8262150000000001,
51.178881999999994
]
]
}
}
下面是映射：
{
"example1": {
"mappings": {
"doc": {
"properties": {
"locations": {
"type": "geo_point"
},
"postDate": {
"type": "date"
},
"status": {
"type": "long"
},
"user": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
}
}
}
}
}
}
我可以使用以下查询添加多个位置。
POST /example1/_update_by_query
{
"query": { …
