Question

这是我用来向SQL发送查询的函数

function Invoke-SQL
{
param (
    [string]$server,
    [string]$database,
    [string]$Query
)

$connectionString = "Data Source=$server; " +
"Integrated Security=SSPI; " +
"Initial Catalog=$database"

$connection = new-object 
system.data.SqlClient.SQLConnection($connectionString)
$command = new-object system.data.sqlclient.sqlcommand($Query, $connection)
$connection.Open()

$adapter = New-Object System.Data.sqlclient.sqlDataAdapter $command

$dataset = New-Object System.Data.DataSet
$adapter.Fill($dataSet) | Out-Null

$connection.Close()

$dataSet.Tables
}

当我运行这样的查询时：

Invoke-SQL -server 'ServerName' -database 'DBname' -Query "SELECT * FROM [DBname].[dbo].[TableName] WHERE UserID = '$userid' AND ComputerName = '$computername'"

我收到以下错误：

ERROR: Exception calling "Fill" with "1" argument(s): "Conversion failed when converting from a character string to uniqueidentifier."
PSDesk_Client.ps1 (358, 2): ERROR: At Line: 358 char: 2
ERROR: +     $adapter.Fill($dataSet) | Out-Null
ERROR: +     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
ERROR:     + CategoryInfo          : NotSpecified: (:) [], 
MethodInvocationException
ERROR:     + FullyQualifiedErrorId : SqlException

似乎有两次这个错误，因为：

首先，它运行查询以从数据库中获取信息
其次，它运行查询以根据需要在数据库上创建/更新信息

我是否让它返回数据或只是发送命令，它对$adapter.Fill($dataSet) | Out-Null不满意。为什么我的两个uniqueidentifiers导致此错误，我该怎么做才能解决此问题？

尝试手动输入记录时，会抛出错误：

错误消息：Guid应包含32个数字，包含4个破折号。

uniqueidentifier是否是错误的数据类型？它必须是一个字符串，但不应该要求采用该格式或任何格式

从PowerShell更新/创建数据库中的记录时出现SQL Server错误
