ExecuteNonQuery error inserting WMI data into sql server db

  • I am attempting to learn/use PowerShell. The following script should be a simple insert of wmi computer system data into a table, but it fails with an error of:

    Exception calling "ExecuteNonQuery" with "0" argument(s): "The parameter data type of UInt32 is invalid."

    At :line:40 char:37

    + $RowsInserted = $cmd.ExecuteNonQuery <<<< ()[System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.SMO') | out-null

    [System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.SMOExtended') | out-null

    # . for the local computer

    # If you want to connect to a remote machine, specify the machine name here.

    $ComputerName = "."

    $CompSys = get-wmiobject -class "Win32_ComputerSystem" -namespace "root\CIMV2" -computername $ComputerName

    # Create SqlConnection object, define connection string, and open connection

    $con = New-Object System.Data.SqlClient.SqlConnection

    $con.ConnectionString = "Server=MySQLServer; Database=MyDatabase; Integrated Security=true"


    foreach ($property in $CompSys) {

    # Create SqlCommand object, define command text, and set the connection

    $cmd = New-Object System.Data.SqlClient.SqlCommand

    $cmd.CommandText = "INSERT INTO ComputerInformation(FullComputerName, ComputerDescription, ComputerSystemType, ComputerManufacturer, ComputerModel, NumberProcessors, TotalPhysicalMemory)

    VALUES (@Name, @ComputerDescription, @ComputerSystemType, @ComputerManufacturer, @ComputerModel, @NumberProcessors, @TotalPhysicalMemory)"

    $cmd.Connection = $con

    # Add parameters to pass values to the INSERT statement

    $cmd.Parameters.AddWithValue("@Name", $property.Name) | Out-Null

    $cmd.Parameters.AddWithValue("@ComputerDescription", $property.Description) | Out-Null

    $cmd.Parameters.AddWithValue("@ComputerSystemType", $property.SystemType) | Out-Null

    $cmd.Parameters.AddWithValue("@ComputerManufacturer", $property.Manufacturer) | Out-Null

    $cmd.Parameters.AddWithValue("@ComputerModel", $property.Model) | Out-Null

    $cmd.Parameters.AddWithValue("@NumberProcessors", $property.NumberOfProcessors) | Out-Null

    $cmd.Parameters.AddWithValue("@TotalPhysicalMemory", $property.TotalPhysicalMemory) | Out-Null

    # Execute INSERT statement

    $RowsInserted = $cmd.ExecuteNonQuery() <<<<**ERROR OCCURS HERE**

    Could someone point me in the correct direction please?

    Thank you.

  • Thanks, but nevermind. I figured it out last night. I had to cast $property.NumberOfProcessors and $property.TotalPhysicalMemory into [Int32]$property.NumberOfProcessors and [Int64]$property.TotalPhysicalMemory. Silly datatypes anyway.
