Powershell and SQL parameters. If empty string, pass DBNull

Question

I got this parameter:

$objDbCmd.Parameters.Add(\"@telephone\", [System.Data.SqlDbType]::VarChar, 18) | Out-Null;
$objDbCmd.Parameters[\"@telephone\"].Value =         


        

Answer 1

I don't know about powershell, but in C# I would do something like this:

if ([string]::IsNullOrEmpty($objUser.Telephone))
{
 $objDbCmd.Parameters["@telephone"].Value = [DBNull]::Value;
}
else
{
 $objDbCmd.Parameters["@telephone"].Value = $objUser.Telephone;
}
