Script PowerShell update SQL Server with csv - powershell

Question

I am trying to make a script that allows to update my SQL Server database from several CSV files with different names, example:
LOHNSJSHM_details.csv
ZULTNQNIW_details.csv
...
Once the data is updated, the file must be deleted automatically.
Here's what I started doing:
If ((Get-PSSnapin | where {$_.Name -match "SqlServerCmdletSnapin100"}) -eq $null)
{
Add-PSSnapin SqlServerCmdletSnapin100
}
If ((Get-PSSnapin | where {$_.Name -match "SqlServerProviderSnapin100"}) -eq $null)
{
Add-PSSnapin SqlServerProviderSnapin100
}
$sql_instance_name = 'ServerSQL01\LAB'
$db_name = 'testdb'
$impcsv = ".\Example.csv"
$data = import-csv $impcsv
$count = 1
foreach($i in $data){
$reference = $i.reference
$quantity = $i.quantite
$query = "UPDATE dbo.F_ARTSTOCK (reference,quantity)
SET quantity = '$quantity'
WHERE reference = '$reference'"
$impcsv = invoke-sqlcmd -Database $db_name -Query $query -serverinstance $sql_instance_name
write-host "Processing row ..........$count" -foregroundcolor green
$count = $count + 1
}
My file has 2 columns (Reference, Quantity) and I have to update a SAGE table based on the reference withdraw quantities from each line of my CSV
Thank you for help.

$sql_instance_name = 'ServerSQL01\LAB'
$db_name = 'testdb'
$csv_folder = 'C:\temp'
$csv_completed_folder = 'C:\done'
# assuming only csv-files you want to import are located in $csv_folder
$csv_files = Get-Childitem -Path $csv_folder -Filter '*.csv'
foreach($file in $csv_files) {
$impcsv = $file.FullName
write-host "Processing file ..........$impcsv" -foregroundcolor green
$data = import-csv $impcsv
$count = 1
foreach($i in $data) {
$reference = $i.reference
$quantity = $i.quantite

$impcsv = invoke-sqlcmd -Database $db_name -Query $query -serverinstance $sql_instance_name
write-host "Processing row ..........$count" -foregroundcolor green
$count = $count + 1
