SQL query in powershell Errors on IIF

Question

Hello,
I have put together a Powershell script from examples online to run a SQL query.  The query came from Access and it seems Powershell has a problem with the syntax.
I'm pretty new to scripting and adding SQL to the equation isn't helping.
Powershell code
$SQLServer = "ServerName"
$SQLDBName = "DataBase"
$SqlQuery = 'MyQuery'
$SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = "Server = $SQLServer; Database = $SQLDBName; Integrated Security = True"
$SqlCmd = New-Object System.Data.SqlClient.SqlCommand
$SqlCmd.CommandText = $SqlQuery
$SqlCmd.Connection = $SqlConnection
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $SqlCmd
$DataSet = New-Object System.Data.DataSet
$SqlAdapter.Fill($DataSet)
$SqlConnection.Close()
$DataSet.Tables[0] | ft -AutoSize
SQL Query
SELECT swName AS Server, swRack AS Rack, swEnvironment AS Environment, IIf([dbo.SW_SERVICE_LVL].[swMonday]=1,"Mon") AS [RebootSchedule], dbo.SW_SERVICE_LVL.swMonBeginTime AS [RebootTime], 2 AS Expr
FROM dbo.SW_SERVICE_LVL INNER JOIN dbo.SW_SPECIALTY ON dbo.SW_SERVICE_LVL.swDiscount = dbo.SW_SPECIALTY.swSpecialtyId
WHERE (((IIf([dbo.SW_SERVICE_LVL].[swMonday]=1,"Mon")) Is Not Null) AND ((dbo.SW_SERVICE_LVL.swGrpResp)="IT Group Name") AND ((dbo.SW_SERVICE_LVL.swRootObjectType)="Server"));
Error given is
Exception calling "Fill" with "1" argument(s): "Incorrect syntax near ')'.
Incorrect syntax near 'IIf'."At line:16 char:1
+ $SqlAdapter.Fill($DataSet)
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~

This might be considered a new question but now I got the powershell code to return data from the SQL database.
Now I am looking to output the table to a powershell Array then append the LastRebootTime into that Array.  As far as I can tell, this requires a ForEach loop on each servername returned from the SQL query.  And I'm stuck on getting that working.
Stop thinking like you know what that means.
Where are you getting lastreboottime? Why does it have to be appended.  "Reboottime" is one of thefields in or query.  You don't need it.
¯\_(ツ)_/¯
That is a bit strongly worded.  Here's what I've got and this is still a work in progress.  I've said this before, I am not a scripter.  Now I am stuck on adding the LastBootUpTime column into the table returned from the SQL query.
$SQLServer = "ServerName"
$SQLDBName = "DataBase"
$SqlQuery = 'MyQuery'
$SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = "Server = $SQLServer; Database = $SQLDBName; Integrated Security = True"
$SqlCmd = New-Object System.Data.SqlClient.SqlCommand
$SqlCmd.CommandText = $SqlQuery
$SqlCmd.Connection = $SqlConnection
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $SqlCmd
$DataSet = New-Object System.Data.DataSet
$SqlAdapter.Fill($DataSet) | Out-Null
$arraydata = @($DataSet)
$SqlConnection.Close()
$servers = @($DataSet.Tables[0]) | select -ExpandProperty Server
Try{
foreach ($server in $servers)
$arraydata += @(GWMI -ComputerName $server -Class Win32_OperatingSystem -ErrorAction SilentlyContinue | select @{LABEL="Server";Expression={$_."csname"}}, @{LABEL='LastBootUpTime'
;EXPRESSION={$_.ConverttoDateTime($_.lastbootuptime)}})
}#end try
Catch{
"Can't work with $server"
$DataSet.Tables[0] | ft -AutoSize #Export-Csv -NoTypeInformation -Path c:\sunday.csv
$arraydata
