PowerShell 中的值不能为空错误

Question

我正在尝试将我的 csv 文件导入到我的 sql 数据库中，但我不确定为什么它说

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

尽管我的 csv 文件中没有 Null 值，而且我确保我的 table 列接受空值。


$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\Return22-01-12-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 headers 列，但要仔细检查它们的书写方式.. 使用空格

你的代码忽略了这里的代码

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

要么保留代码并重写 headers（去掉空格），要么确保根据 headers.

使用属性名称

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

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没有意义，因此只保留最后一条记录...
