Question

I use powershell to invoke a sql stored procedure, now I want to redirect the complete set of the output into a .ps1 file, because the the output line is executable in powershell.

I’m trying to use >output.ps1, it works, but I’m checking the output file, it contains a lot of ‘…’ to replace real output.

How to export the complete output? also stripe the header off?

Thanks.

It depends how you invoke the stored procedure. If you’re invoking it within PowerShell, you should be able to collect the output, so I assume you’re starting it as a separate task its own window. Without your actual example, here’s a way to collect the output from the tasklist.exe command. You may find it applicable.

cls
$exe = 'c:\Windows\System32\tasklist.exe'
$processArgs = '/NH'
try {
    Write-Host ("Launching '$exe $processArgs'")
    $info = New-Object System.Diagnostics.ProcessStartInfo
    $info.UseShellExecute = $false 
    $info.RedirectStandardError = $true 
    $info.RedirectStandardOutput = $true 
    $info.RedirectStandardInput = $true 
    $info.WindowStyle = [System.Diagnostics.ProcessWindowStyle]::Hidden
    $info.CreateNoWindow = $true
    $info.ErrorDialog = $false
    $info.WorkingDirectory = $workingDir
    $info.Filename = $exe
    $info.Arguments = $processArgs

    $process = [System.Diagnostics.Process]::Start($info)
    Write-Host ("Launched $($process.Id) at $(Get-Date)")
    <# 
    $process.StandardOutput.ReadToEnd() is a synchronous read. You cannot sync read both output and error streams. 
    $process.BeginOutputReadLine() is an async read. You can do as many of these as you'd like. 
    Either way, you must finish reading before calling $process.WaitForExit()

    $output = $process.StandardOutput.ReadToEnd()

    $process.WaitForExit() | Out-Null 

    Write-Host ("Exited at $(Get-Date)`n$output")

} catch {
    Write-Host ("Failed to launch '$exe $processArgs'")
    Write-Host ("Failure due to $_")
}
$output
