PowerShell中的值不能为空错误

Question

我正在尝试使用这样的方法将我的 csv 文件导入我的 sql 数据库，但我不知道为什么会这样说

Exception calling "ExecuteWithResults" with "1" argument(s): "Value cannot be null.
Parameter name: sqlCommands"

即使我的 csv 文件中没有 Null 值，并且我也确保我的表列接受 null 值。

$s =  New-Object Microsoft.SqlServer.Management.Smo.Server "server name"
$db = $s.Databases.Item("LitHold")
$csvfile = import-csv -delimiter ";" -path "C:\scripts\LitHold-OneDrive\output\Return\2022-01-12-Return.csv"
$csvfile |foreach-object{
    $query = "insert into DailyReport VALUES ('$($_.MIN)','$($_.MID)','$($_.UPN)','$($_.Change)','$($_.Type)','$($_.HoldValue)','$($_.OneDrive)','$($_.Mailbox)','$($_.Created)','$($_.Modified)','$($_.MultMID)','$($_.Account)','$($_.ExistOD)')"
}

$result = $db.ExecuteWithResults($query)

# Show output
$result.Tables[0]

我的 csv 文件

//The top one is my columns name and it's already inside my table 
"MIN","MID","UPN","Change","Type","Hold Value","OneDrive","Mailbox","Created","Modified","Mult MID","Account","Exist OD"

"338780228","lzlcdg","lzlcdg@NAMQA.COM","Hold Created","OneDrive and Mailbox","Y","https://devf-my.sharepoint.com/personal/lzlcdg_namqa_corpqa_geuc_corp_com","lzlcdg@NAMQA.CORPQA.GEUC.CORP.COM","1/11/2022 11:38:57 AM","1/11/2022 11:38:57 AM","N","",""

不要删除列标题，但要仔细检查它们是如何编写的。使用空格

你的代码忽略了这里的那些

$($_.HoldValue) --> $($_.'Hold Value')
$($_.MultMID) --> $($_.'Mult MID')
$($_.ExistOD) --> $($_.'Exist OD')

要么保留代码并重写标题（去掉空格），要么确保根据标题使用属性名称。

^{通过删除列标题，csv 文件中的第一行将用作列标题，除非您提供带有参数-Header 的新标题。如果多次遇到相同的字段值，删除标题将导致问题，因为列标题必须是唯一的}

然后就是这一行：

$result = $db.ExecuteWithResults($csvfile)

应该是

$result = $db.ExecuteWithResults($query)

并且循环遍历 csv 文件的记录并在该循环内覆盖您的查询字符串在每次迭代中都没有意义，因此只会保留最后一条记录...
