Question

我实现了导入几个Excel文件以更新数据库SQL Server中的表的脚本，但是运行脚本时出现错误：

invoke-sqlcmd：语法不正确，而不是'（'。 AucaractèreC：\ Users \ WEBadmin \ Desktop \ updateDb.ps1：38：15 + ... $ impcsv = invoke-sqlcmd-数据库$ db_name-查询$ query -serverin ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~ + CategoryInfo：InvalidOperation：（:) [Invoke-Sqlcmd]，SqlPowerShellSqlExecutionException + FullyQualifiedErrorId：SqlError，Microsoft.SqlServer.Management.PowerShell.GetScriptCommand

这是我的PS脚本：

$sql_instance_name = 'SERVER\SERV100'
$db_name = 'TOTO'
$table = 'dbo.F_ARTSTOCK'

$csv_folder = 'C:\IMPORTS'
$csv_completed_folder = 'C:\done'
$batchsize = 50000 

# assuming only csv-files you want to import are located in $csv_folder
$csv_files = Get-Childitem -Path $csv_folder -Filter '*.csv'

# Build the sqlbulkcopy connection, and set the timeout to infinite 
$connectionstring = "Data Source=$sql_instance_name;Integrated Security=true;Initial Catalog=$db_name;" 
$bulkcopy = New-Object Data.SqlClient.SqlBulkCopy($connectionstring, [System.Data.SqlClient.SqlBulkCopyOptions]::TableLock) 
$bulkcopy.DestinationTableName = $table 
$bulkcopy.bulkcopyTimeout = 0 
$bulkcopy.batchsize = $batchsize 

foreach($file in $csv_files) {
    $impcsv = $file.FullName

    write-host "Processing file ..........$impcsv" -foregroundcolor green
    $data = import-csv $impcsv

    $count = 1

    foreach($i in $data) {

    Write-Host ($data | Format-Table | Out-String)

    $reference = $i.Reference
    $quantity = $i.Quantity

    $query = "UPDATE dbo.F_ARTSTOCK (AR_Ref,AS_QteSto)
              SET dbo.F_ARTSTOCK.AS_QteSto = dbo.F_ARTSTOCK.AS_QteSto - '$quantity'
              WHERE dbo.F_ARTSTOCK.AR_Ref = '$reference'"

    $impcsv = invoke-sqlcmd -Database $db_name -Query $query  -serverinstance $sql_instance_name 

    write-host "Processing row ..........$count" -foregroundcolor green

    $count  = $count + 1

    }
}

感谢您的帮助。
