PowerShell and SQL server - sql

Question

Currently I'm working on a PowerShell script which is extracting info about OS, hotfix and installed software.
Well, everything is working well if I want to export to txt file - everything.
But my new task is to upload this information to sql server.
So I'm creating a foreach loop to print installed software and put everything in server. PowerShell isn't showing any errors but I can't get this data into sql server.
$conn = New-Object System.Data.SqlClient.SqlConnection
$conn.ConnectionString = "Data Source=myserver; Initial Catalog=table; Integrated Security=SSPI;"
$conn.Open()
$soft = Get-WmiObject Win32_Product
$cmd = New-Object System.Data.SqlClient.SqlCommand
$cmd.Connection = $conn
$cmd = $conn.CreateCommand()
foreach ($Software in $soft){
$query = "INSERT INTO dbo.mytable (SoftName, SoftVersion) VALUES ('$($Software.Name)', $($Software.Version))" }
$cmd.CommandText = $query
$result = $cmd.ExecuteNonQuery
$conn.close()
So the idea is that when I run this script, I get all software installed on pc listed in sql server.
SoftName: SoftVersion:
Office 14.202
Sql 15
Thanks!

Answer 1

What do you get in $result variable when you run your script?
I believe, that you get signatures of overloaded methods with the name ExecuteNonQuery. The proper method call looks like this:
$result = $cmd.ExecuteNonQuery()
If you see errors I would recommend you to use code below to get full information about them:
$ErrorActionPreference = "Stop"
$Error.Clear()
try {
# Your code
}
catch {
$Error | Format-List * -Force
}

You are overwriting the insert command instead of appending into it. In addition, as levgen points out, you are missing method call syntax:
foreach ($Software in $soft){
$query = "INSERT INTO dbo.mytable (SoftName, SoftVersion) VALUES ('$($Software.Name)', $($Software.Version))"
} # Oops!
# Now $query contains only the last insert statement.
$cmd.CommandText = $query
$result = $cmd.ExecuteNonQuery # Should be .ExecuteNonQuery()
$conn.close()
Try something like so,
foreach ($Software in $soft){
$query += "INSERT INTO dbo.mytable (SoftName, SoftVersion) VALUES ('$($Software.Name)', $($Software.Version));"
} # Appending insert staements
# Now $query should contain lots of insert staements
$cmd.CommandText = $query
$result = $cmd.ExecuteNonQuery()
$conn.close()
