#### [ CLI ]

**AWS CLI**  
**Contoh 1: Untuk menanyakan tabel**  
`query`Contoh berikut query item dalam `MusicCollection` tabel. Tabel memiliki kunci hash-and-range utama (`Artist`dan`SongTitle`), tetapi kueri ini hanya menentukan nilai kunci hash. Ini mengembalikan judul lagu oleh artis bernama “No One You Know”.  

```
aws dynamodb query \
    --table-name MusicCollection \
    --projection-expression "SongTitle" \
    --key-condition-expression "Artist = :v1" \
    --expression-attribute-values file://expression-attributes.json \
    --return-consumed-capacity TOTAL
```
Isi dari `expression-attributes.json`:  

```
{
    ":v1": {"S": "No One You Know"}
}
```
Output:  

```
{
    "Items": [
        {
            "SongTitle": {
                "S": "Call Me Today"
            },
            "SongTitle": {
                "S": "Scared of My Shadow"
            }
        }
    ],
    "Count": 2,
    "ScannedCount": 2,
    "ConsumedCapacity": {
        "TableName": "MusicCollection",
        "CapacityUnits": 0.5
    }
}
```
Untuk informasi selengkapnya, lihat [Bekerja dengan Kueri di DynamoDB di](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Query.html) Panduan Pengembang Amazon *DynamoDB*.  
**Contoh 2: Untuk menanyakan tabel menggunakan pembacaan yang sangat konsisten dan melintasi indeks dalam urutan menurun**  
Contoh berikut melakukan kueri yang sama dengan contoh pertama, tetapi mengembalikan hasil dalam urutan terbalik dan menggunakan pembacaan yang sangat konsisten.  

```
aws dynamodb query \
    --table-name MusicCollection \
    --projection-expression "SongTitle" \
    --key-condition-expression "Artist = :v1" \
    --expression-attribute-values file://expression-attributes.json \
    --consistent-read \
    --no-scan-index-forward \
    --return-consumed-capacity TOTAL
```
Isi dari `expression-attributes.json`:  

```
{
    ":v1": {"S": "No One You Know"}
}
```
Output:  

```
{
    "Items": [
        {
            "SongTitle": {
                "S": "Scared of My Shadow"
            }
        },
        {
            "SongTitle": {
                "S": "Call Me Today"
            }
        }
    ],
    "Count": 2,
    "ScannedCount": 2,
    "ConsumedCapacity": {
        "TableName": "MusicCollection",
        "CapacityUnits": 1.0
    }
}
```
Untuk informasi selengkapnya, lihat [Bekerja dengan Kueri di DynamoDB di](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Query.html) Panduan Pengembang Amazon *DynamoDB*.  
**Contoh 3: Untuk menyaring hasil tertentu**  
Contoh berikut query `MusicCollection` tetapi mengecualikan hasil dengan nilai-nilai tertentu dalam atribut. `AlbumTitle` Perhatikan bahwa ini tidak mempengaruhi `ScannedCount` atau`ConsumedCapacity`, karena filter diterapkan setelah item telah dibaca.  

```
aws dynamodb query \
    --table-name MusicCollection \
    --key-condition-expression "#n1 = :v1" \
    --filter-expression "NOT (#n2 IN (:v2, :v3))" \
    --expression-attribute-names file://names.json \
    --expression-attribute-values file://values.json \
    --return-consumed-capacity TOTAL
```
Isi dari `values.json`:  

```
{
    ":v1": {"S": "No One You Know"},
    ":v2": {"S": "Blue Sky Blues"},
    ":v3": {"S": "Greatest Hits"}
}
```
Isi dari `names.json`:  

```
{
    "#n1": "Artist",
    "#n2": "AlbumTitle"
}
```
Output:  

```
{
    "Items": [
        {
            "AlbumTitle": {
                "S": "Somewhat Famous"
            },
            "Artist": {
                "S": "No One You Know"
            },
            "SongTitle": {
                "S": "Call Me Today"
            }
        }
    ],
    "Count": 1,
    "ScannedCount": 2,
    "ConsumedCapacity": {
        "TableName": "MusicCollection",
        "CapacityUnits": 0.5
    }
}
```
Untuk informasi selengkapnya, lihat [Bekerja dengan Kueri di DynamoDB di](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Query.html) Panduan Pengembang Amazon *DynamoDB*.  
**Contoh 4: Untuk mengambil hanya jumlah item**  
Contoh berikut mengambil hitungan item yang cocok dengan query, tetapi tidak mengambil salah satu item itu sendiri.  

```
aws dynamodb query \
    --table-name MusicCollection \
    --select COUNT \
    --key-condition-expression "Artist = :v1" \
    --expression-attribute-values file://expression-attributes.json
```
Isi dari `expression-attributes.json`:  

```
{
    ":v1": {"S": "No One You Know"}
}
```
Output:  

```
{
    "Count": 2,
    "ScannedCount": 2,
    "ConsumedCapacity": null
}
```
Untuk informasi selengkapnya, lihat [Bekerja dengan Kueri di DynamoDB di](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Query.html) Panduan Pengembang Amazon *DynamoDB*.  
**Contoh 5: Untuk menanyakan indeks**  
Contoh berikut query indeks `AlbumTitleIndex` sekunder lokal. Query mengembalikan semua atribut dari tabel dasar yang telah diproyeksikan ke indeks sekunder lokal. Perhatikan bahwa saat menanyakan indeks sekunder lokal atau indeks sekunder global, Anda juga harus memberikan nama tabel dasar menggunakan `table-name` parameter.  

```
aws dynamodb query \
    --table-name MusicCollection \
    --index-name AlbumTitleIndex \
    --key-condition-expression "Artist = :v1" \
    --expression-attribute-values file://expression-attributes.json \
    --select ALL_PROJECTED_ATTRIBUTES \
    --return-consumed-capacity INDEXES
```
Isi dari `expression-attributes.json`:  

```
{
    ":v1": {"S": "No One You Know"}
}
```
Output:  

```
{
    "Items": [
        {
            "AlbumTitle": {
                "S": "Blue Sky Blues"
            },
            "Artist": {
                "S": "No One You Know"
            },
