我正在尝试通过 Azure 自动化为多个 AzureSQL 数据库循环调用 SQLcmd。循环中的第一项执行,但所有其余的都失败了:
Invoke-Sqlcmd:建立与 SQL Server 的连接时发生与网络相关或特定于实例的错误。服务器未找到或无法访问。验证实例名称是否正确以及 SQL Server 是否配置为允许远程连接。(提供者:命名管道提供者,错误:40 - 无法打开与 SQL Server 的连接)
我猜我需要在执行下一个之前关闭第一个 invoke-sqlcmd 的连接,但还没有找到直接的方法来使用 invoke-sqlcmd 完成此操作。这是我的循环:
param(
# Parameters to Pass to PowerShell Scripts
[parameter(Mandatory=$true)][String] $azureSQLServerName = "myazuresql",
[parameter(Mandatory=$true)][String] $azureSQLCred = "myazureautosqlcred"
)
# DB Name Array
$dbnamearray = @("database1","database2","database3")
$dbnamearray
# Datatable Name
$tabName = "RunbookTable"
#Create Table object
$table = New-Object system.Data.DataTable "$tabName"
#Define Columns
$col1 = New-Object system.Data.DataColumn dbname,([string])
#Add the Columns
$table.columns.add($col1)
# Add Row and Values for dname Column
ForEach ($db in $dbnamearray)
{
$row = $table.NewRow()
$row.dbname = $db
#Add the row to the table
$table.Rows.Add($row)
}
#Display the table
$table | format-table -AutoSize
# Loop through the datatable using the values per column
$table | ForEach-Object {
# Set loop variables as these are easier to pass then $_.
$azureSQLDatabaseName = $_.dbname
# Execute SQL Query Against Azure SQL
$azureSQLServerName = $azureSQLServerName + ".database.windows.net"
$Cred = Get-AutomationPSCredential -Name $azureSQLCred
$SQLOutput = $(Invoke-Sqlcmd -ServerInstance $azureSQLServerName -Username $Cred.UserName -Password $Cred.GetNetworkCredential().Password -Database $azureSQLDatabaseName -Query "SELECT * FROM INFORMATION_SCHEMA.TABLES " -QueryTimeout 65535 -ConnectionTimeout 60 -Verbose) 4>&1
Write-Output $SQLOutput
}
