Description

O cmdlet Get-AzStorageBlobQueryResult aplica uma instrução SQL (Structured Query Language) simples no conteúdo de um blob e salva o subconjunto consultado dos dados em um arquivo local.

Exemplos

Exemplo 1: Consultar um 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

Este comando consulta um blob com configuração de entrada como csv e configuração de saída como json, e salva a saída no arquivo local "c:\resultfile.json".

Exemplo 2: Consultar um instantâneo de 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

Esse comando primeiro obtém um objeto de blob para instantâneo de blob, depois consulta o instantâneo de blob e mostra o erro de consulta de inclusão de resultado.
