Question

我正在尝试使用Get-AzTableRow来检索Azure表行，然后对其进行更新。但是该cmdlet引发以下错误：

  PS C:\WINDOWS\system32> Get-AzTableRow -ColumnName "NsgName" -Value "subnet1invnet4-nsg" -Operator "Equal"
  You cannot call a method on a null-valued expression.
  At C:\Users\sayghosh\Documents\WindowsPowerShell\Modules\AzTable\2.0.2\AzureRmStorageTableCoreHelper.psm1:52 char:4
   +             $Results = $Table.ExecuteQuerySegmentedAsync($TableQuery, ...
   +             ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
   + CategoryInfo          : InvalidOperation: (:) [], RuntimeException
   + FullyQualifiedErrorId : InvokeMethodOnNull

PS C:\WINDOWS\system32> Get-AzTableRow -table $storageCloudTable
Cannot find an overload for "ExecuteQuerySegmentedAsync" and the argument count: "2".
At C:\Users\sayghosh\Documents\WindowsPowerShell\Modules\AzTable\2.0.2\AzureRmStorageTableCoreHelper.psm1:52 char:4
 +             $Results = $Table.ExecuteQuerySegmentedAsync($TableQuery, ...
 +             ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 + CategoryInfo          : NotSpecified: (:) [], MethodException
 + FullyQualifiedErrorId : MethodCountCouldNotFindBest

这里的任何线索都会有所帮助。

签出以下脚本来设置存储上下文，并使用cloudtable读取并更新表行。

#To install the AzTable module if not already installed
#Install-Module AzTable
#set the subscription contenxt if not already set
#Set-AzContext -Subscription "Subscription Name"

$storageAccountName = "storageaccountName"
$tableName = "storagetableName"
$partitionKey1 = "partitionKey"
$resourceGroup = "ResourceGroup Name"


$storageAccount = Get-AzStorageAccount -ResourceGroupName $resourceGroup -Name  $storageAccountName

# Get the Storage Contenxt
$ctx = $storageAccount.Context

# Usage of CloudTable is mandatory when working with AzTable PowerShell module.
$cloudTable = (Get-AzStorageTable -Name $tableName -Context $ctx ).CloudTable

# different ways to get the table row
#Get-AzTableRow -table $cloudTable -customFilter "(username eq 'bob2')"
#Get-AzTableRow -Table $cloudTable -ColumnName "username" -Value "bob2" -Operator Equal

#Create a filter and get the entity to be updated.
[string]$filter =    [Microsoft.Azure.Cosmos.Table.TableQuery]::GenerateFilterCondition("username",       
[Microsoft.Azure.Cosmos.Table.QueryComparisons]::Equal,"bob2")

$user = Get-AzTableRow  -table $cloudTable -customFilter $filter

# Change the entity.
$user.username = "james"

# To commit the change, pipe the updated record into the update cmdlet.
$user | Update-AzTableRow -table $cloudTable

# To see the new record, query the table.
Get-AzTableRow -table $cloudTable -customFilter "(username eq 'james')"`

希望这会有所帮助。

在Get-AzTableRow中找不到“ ExecuteQuerySegmentedAsync”的重载和参数计数：“ 2”
