Description

Get-Az 儲存體 BlobQueryResult Cmdlet 會在 Blob 的內容上套用簡單的結構化查詢語言 (SQL) （SQL）語句，並將查詢的數據子集儲存至本機檔案。

範例

範例 1：查詢 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

此命令會以輸入設定為 csv，並將輸出組態儲存為 json，並將輸出儲存至本機檔案「c：\resultfile.json」。。

範例 2：查詢 Blob 快照集

$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

此命令會先取得 Blob 快照集的 Blob 對象，然後查詢 Blob 快照集，並顯示結果包含查詢錯誤。
