Question

我想根据某些条件从azure存储表中删除记录。我在天蓝色存储表中有像datemodified这样的列。我的查询看起来像

datemodifed < (Get-Date).ToUniversalTime().AddDays(-10)

任何人都可以告诉我如何使用powershell脚本根据上述条件逐个删除记录。提前致谢

Working with Azure Storage Tables from PowerShell

Windows Azure Storage Cmdlets

TableOperation.Delete接受表实体。见这里：https://msdn.microsoft.com/en-us/library/microsoft.windowsazure.storage.table.tableoperation.delete.aspx

在这里查看TableQuery类https://msdn.microsoft.com/en-us/library/microsoft.windowsazure.storage.table.tablequery_methods.aspx

使用这个命令：

$entityToDelete | Remove-AzTableRow -table $cloudTable

要获取 $cloudTable，您需要先获取存储帐户和实体的上下文。例如你可以使用这个脚本：

$storageAccountName = "MyStorage"
$resourceGroup = "MyRG"
$tableName = "MyTable"
$columnName = "MyColum"
$value = "EntityValueToSearch"

$storageAccount = Get-AzStorageAccount `
  -ResourceGroupName $resourceGroup `
  -Name $storageAccountName
$ctx = $storageAccount.Context 

$storageTable = Get-AzStorageTable –Name $tableName –Context $ctx
$cloudTable = ($storageTable).CloudTable

[string]$filter = `
  [Microsoft.Azure.Cosmos.Table.TableQuery]::GenerateFilterCondition($columnName,`
  [Microsoft.Azure.Cosmos.Table.QueryComparisons]::Equal,$value)

# Get entity
$entityToDelete = Get-AzTableRow `
    -table $cloudTable `
    -customFilter $filter

$entityToDelete | Remove-AzTableRow -table $cloudTable
