Display results of a SQL query with PowerShell - powershell

Question

I have been provided a PS script which calls a simple SQL query, displays the results and plays a voice... supposedly. This is designed to go into a BI gadget which just displays a number from the PS script.
The correct count from the query is not displaying and is for some reason stuck on 2.
$sql = "<simple COUNT query>"
$items = invoke-sql -server "<server name>" -database "<db name>" -user "<uname>" -password "<password>" -sql $sql -timeout 180
$day = (get-date).DayOfWeek.Value__
# $items[0] = 10
if ($day -ge 1 -and $day -le 5)
{
$date = Get-Date
if ($date.Hour -ge 8 -and $date.Hour -lt 17)
{
if ($items[0] -gt 0)
{
$voice = New-Object -Com sapi.spvoice
$voice.Rate = 1
$voice.volume = 100
Do {
Start-Sleep -s 1
$Counter = Get-Date
}
Until ($Counter.Second/15 -is [int])
if ($items[0] -gt 1)
{
[void]$voice.Speak("New Ticket.")
}
else
{
[void]$voice.Speak("New Ticket.")
}
}
}
}
Write-Output $items.Count
The SQL component I have no issues with and definitely works correctly when run, but I have no experience with PowerShell scripting so can someone please assist?

Answer 1

$Items.count is going to give you the number of records in your result set. Technically these are DataRow objects and $Items is a DataTable. If you are getting multiple rows back, you need to determine WHICH row you want to show.
Basically the way to would query the returned DataTable is:
($Items[x]).Column
Where x is the 0-indexed row you want to return and Column is the name of the column you want to return. So if you want the ItemCount column from the second row you would use:
($Items[1]).ItemCount
