Getting data from SQL Server 2008 with Powershell - sql-server

Question

I'm having some difficulties getting data from a simple stored procedure in SQL Server working. I have a Powershell script that needs to get variables filled from 3 columns (the procedure just returns 1 row)
Here's what I have that isn't working. Somehow I'm not referencing the column value correctly. I've tried various methods, but usually get the error "Cannot index into a null array". I don't want to iterate through the resultset, I just want to directly set some values from the one row returned into variables
$conn = new-object Microsoft.SqlServer.Management.Common.ServerConnection
$conn.ConnectionString = `
"Server=ServerName;Database=ShopDB;Integrated Security=True"
$sqlQuery = new-object System.Collections.Specialized.StringCollection
$sqlQuery.Add("JobSettingsGet")
$Resultset = $conn.ExecuteWithResults($sqlQuery)
# $UserName = $table.Rows(0).Columns(0)
# error - Method invocation failed because [System.Data.DataTable] doesn't
# contain a method named 'Rows'.
# $UserName = $table.Rows[0].Columns[0]
# error - cannot index null array
# $UserName = $table.Row(0).Column(0)
# error - Cannot index into a null array, also Method invocation failed
# because [System.Data.DataTable] doesn't contain a method named 'Row'.
# $UserName = $table.Rows[0].Columns[1].Value
# error - cannot index null array
I'd like to use the column name if possible, too.
Any pointers?
thanks,
Sylvia

You could use System.Data.SqlClient.SqlConnection instead of SqlServer.Management class
$conn = New-Object Data.Sqlclient.Sqlconnection`
("Data Source=DATABASE;Initial Catalog=master;Integrated Security=SSPI;")
$adapter = New-Object Data.Sqlclient.Sqldataadapter("exec sp_who2", $conn)
$set = new-object data.dataset
$adapter.fill($set)
$table = new-object data.datatable
$table = $set.tables[0]
In order to print the whole table, just use format-table
$table | ft -AutoSize
To get a column by name, use the foreach iterator and access note properties by name
$table | % {$_.login}
Ed: Here is the same query by using SqlServer.Management.
[void][Reflection.Assembly]::LoadWithPartialName`
("Microsoft.SqlServer.ConnectionInfo")
$conn = new-object Microsoft.SqlServer.Management.Common.ServerConnection
$conn.ConnectionString = `
"Server=ServerName;Database=ShopDB;Integrated Security=True"
$sqlQuery = new-object System.Collections.Specialized.StringCollection
$sqlQuery.Add("exec sp_who2")
$resultset = $conn.ExecuteWithResults($sqlQuery)
Access the results by picking the zeroeth resultset, zeroeth table, zeroeth row and item by name
$resultset[0].tables.Item(0).Rows[0].Item("Login")
