Question

Good day
Iam looking way how to run sql command only if exist file/s in specific folder ? I read lot of staff but i cant not fit my skript . I do not want do make SSIS I want do to in Powershell.
Then I will put into MSQL Job Agent powershell script wchich will run every hour . If this Job find .csv file /s then will start other Job.
Thank you for opinion.
$SourceFile = "C:\Import\FOLDER\report\Old\test\*.csv"
Action = "Invoke-Sqlcmd -ServerInstance "100.000.000.001" -Query "USE msdb ; EXEC dbo.sp_start_job N'MSSQLJOBNAME' ;"
if(Test-Path -Path $SourceFile)
{
"Invoke-Sqlcmd -ServerInstance "100.000.000.001" -Query "USE msdb ; EXEC dbo.sp_start_job N'MSSQLJOBNAME' ;"
}

specifying the folder and *.csv in a variable is not enough; you have to get the filelist.
for running the sql command in the database msdb I added the parameter -Database
$SourceFilesArray = Get-ChildItem -Path "C:\Import\FOLDER\report\Old\test\" -Filter "*.csv"
if($SourceFilesArray) {
# $SourceFilesArray is not empty/contains list of specified files
Invoke-Sqlcmd -ServerInstance "100.000.000.001" -Database "msdb" -Query "EXEC dbo.sp_start_job 'MSSQLJOBNAME'"
} else {
# run this if $SourceFilesArray is empty/no files found
Invoke-Sqlcmd -ServerInstance "100.000.000.001" -Database "msdb" -Query "EXEC dbo.sp_start_job 'MSSQLJOBNAME'"
}
