Description
The Get-AzStorageBlobQueryResult cmdlet applies a simple Structured Query Language (SQL) statement on a blob's contents and save the queried subset of the data to a local file.
Examples
Example 1: Query a 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
This command querys a blob succsssfully with input config as csv, and output config as json, and save the output to local file "c:\resultfile.json".
Example 2: Query a blob snapshot
$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
This command first gets a blob object for blob snapshot, then queries the blob snapshot and show the result include query error.
