SQL Several Selected Tree Nodes?

I'm loading a Listview based on SQL query of more than one TreeView SelectedNode(s), but unsure how to procede. I have checkboxes in the Treeview to allow multiple selections. I can easily build a query based on just one TreeView Node like so:  "Select Distinct * From WinLogs Where ComputerName = '" + treeView1.SelectedNode.Text + "'";
