How To Execute MS Access Query with OLEDB.12

I am looking for the syntax for executing MS Access named query using Microsoft.ACE.OLEDB.12.0 command object.

I see lots of examples using tables but non for queries yet. Swapping out the table name for the query name seems not to work. i.e. select * from 'myquery'

Here is my code snippet:

$OleDbConn = New-Object "System.Data.OleDb.OleDbConnection";
$OleDbCmd = New-Object "System.Data.OleDb.OleDbCommand";
$OleDbAdapter = New-Object "System.Data.OleDb.OleDbDataAdapter";
$DataTable = New-Object "System.Data.DataTable";

$OleDbConn.Open();

$OleDbCmd.Connection = $OleDbConn;
$OleDbCmd.CommandText = "'myQuery'"; # name query in MS Access db
$OleDbCmd.CommandType = [System.Data.CommandType]::StoredProcedure;
$OleDbAdapter.SelectCommand = $OleDbCmd;

$RowsReturned = $OleDbAdapter.Fill($DataTable);
Write-Host $RowsReturned;

Error: Exception calling "Fill" with "1" argument(s): "The Microsoft Access database engine cannot find the input table or query ''Lab Manual''. Make sure it exists and that its name is spelled correctly."

The trick was to append the command 'Execute' before the query name and use square brackets around the query name.

$OleDbConn = New-Object "System.Data.OleDb.OleDbConnection";
$OleDbCmd = New-Object "System.Data.OleDb.OleDbCommand";
$OleDbAdapter = New-Object "System.Data.OleDb.OleDbDataAdapter";
$DataTable = New-Object "System.Data.DataTable";

$OleDbConn.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=c:\temp\labmanual.mdb;";
$OleDbCmd.Connection = $OleDbConn;
$OleDbCmd.CommandText = "Execute [myQuery]";

$OleDbAdapter.SelectCommand = $OleDbCmd;

$OleDbConn.Open();
$RowsReturned = $OleDbAdapter.Fill($DataTable);


Write-Host $RowsReturned;

$OleDbConn.Close();
