Deskripsi

Cmdlet Get-AzStorageBlobQueryResult menerapkan pernyataan Bahasa Permintaan Terstruktur sederhana (SQL) pada konten blob dan menyimpan subset data yang dikueri ke file lokal.

Contoh

Contoh 1: Mengkueri blob

$inputconfig = New-AzStorageBlobQueryConfig -AsCsv -HasHeader

$outputconfig = New-AzStorageBlobQueryConfig -AsJson

$queryString = "SELECT * FROM BlobStorage WHERE Name = 'a'"

$result = Get-AzStorageBlobQueryResult -Container $containerName -Blob $blobName -QueryString $queryString -ResultFile "c:\resultfile.json" -InputTextConfiguration $inputconfig -OutputTextConfiguration $outputconfig -Context $ctx

$result

BytesScanned FailureCount BlobQueryError
------------ ------------ --------------
         449            0

Perintah ini mengkueri blob secara succsssful dengan konfigurasi input sebagai csv, dan konfigurasi output sebagai json, dan menyimpan output ke file lokal "c:\resultfile.json".

Contoh 2: Mengkueri rekam jepret blob

$blob = Get-AzStorageBlob -Container $containerName -Blob $blobName -SnapshotTime "2020-07-29T11:08:21.1097874Z" -Context $ctx

$inputconfig = New-AzStorageBlobQueryConfig -AsCsv -ColumnSeparator "," -QuotationCharacter """" -EscapeCharacter "\" -RecordSeparator "`n" -HasHeader

$outputconfig = New-AzStorageBlobQueryConfig -AsJson -RecordSeparator "`n" 

$queryString = "SELECT * FROM BlobStorage WHERE _1 LIKE '1%%'"

$result = $blob | Get-AzStorageBlobQueryResult -QueryString $queryString -ResultFile $localFilePath -InputTextConfiguration $inputconfig -OutputTextConfiguration $outputconfig

$result

BytesScanned FailureCount BlobQueryError
------------ ------------ --------------
   187064971            1 {ParseError}  



$result.BlobQueryError

Name       Description                                                   IsFatal Position
----       -----------                                                   ------- --------
ParseError Unexpected token '1' at [byte: 3077737]. Expecting token ','.    True  7270632

Perintah ini pertama-tama mendapatkan objek blob untuk rekam jepret blob, lalu mengkueri rekam jepret blob dan memperlihatkan hasilnya termasuk kesalahan kueri.
