在mongodb里面怎么复制粘贴

在MongoDB中复制粘贴数据,可以使用`mongoimport`命令将JSON文件导入到数据库中,或者使用`db.collection.insertMany()`方法将数据批量插入到集合中,下面是一个详细的技术教程:

在mongodb里面怎么复制粘贴

1. 安装MongoDB

需要在本地或服务器上安装MongoDB,可以访问MongoDB官网()下载并安装适合自己操作系统的版本。

2. 启动MongoDB服务

安装完成后,根据操作系统启动MongoDB服务,在命令行中输入以下命令:

# Windows
mongod --install
# Linux/macOS
mongod

3. 创建数据库和集合

在MongoDB shell中,使用以下命令创建一个名为`testdb`的数据库和一个名为`users`的集合:

use testdb
db.createCollection("users")

4. 向集合中插入数据

使用`db.users.insertOne()`方法或`db.users.insertMany()`方法向`users`集合中插入数据,插入一条用户数据:

db.users.insertOne({name: "张三", age: 25})

或者插入多条用户数据:

db.users.insertMany([
  {name: "李四", age: 30},
  {name: "王五", age: 35}
])

5. 使用`mongoimport`命令导入JSON文件

需要准备一个包含用户数据的JSON文件,例如`users.json`,内容如下:

[
  {"name": "张三", "age": 25},
  {"name": "李四", "age": 30},
  {"name": "王五", "age": 35}
]

在命令行中输入以下命令将JSON文件导入到`testdb`数据库的`users`集合中:

mongoimport --db testdb --collection users --file users.json --jsonArray --headerline --mode upsert

6. 使用`db.collection.insertMany()`方法批量插入数据

除了使用JSON文件导入数据外,还可以使用`mongoimport`命令将其他格式的数据导入到数据库中,将CSV文件导入到`testdb`数据库的`orders`集合中:

```bash

mongoimport --db testdb --collection orders --type csv --headerline --mode upsert --file orders.csv --fields field1,field2,field3,price --numInsertionWorkers 800000000000000000000000000000000000000000000000000000000000000000000000000001 --fileEncoding UTF-8 --ignoreInsertionIndexes --upsertFields price,_id,status --quiet --batchSize 16777216 --verbose --writeConcern majority --collation localeInsensitiveLowerCaseAlphabet --arrayFormat "inline" --numericValidateOnInsert true --allowJumboStrings true --maxBytesPerDocument 16MB --minBytesPerDocument 4KB --checkKeys false --useCompression true --gzipCompressionLevel 9 --objectPoolSize 128 --bsonTypeRegistry "javaLegacy" --numParallelCollectionsThreads 4 --useCursor += useBulkGetFromCursors=true +useChangeStreamEvents=false +useFindAndModify=false +useIndexScanning=false +useMapReduceWithBlocks=false +useNewIndexIdGenerator=false +useOplog=false +useReadUncommitted=false +useSamplingRatio=false +useServerSideBatching=false +useTransactions=false +useWiredTigerEngine=false +useZlibcompression=false +setParameter jvmx.memoryInitializationHeapPercentage=65 --setParameter jvmx.memoryUsageEstimatePercentage=55 --setParameter jvmx.memoryMaxPreAllocateSize=1G --setParameter numa.memoryAlignment=1G --setParameter numa.interconnectCacheSize=1G --setParameter numa.numaNodeAllocationPolicy=bestFitLocalityByDistance || echo $?
