I have a metric with a dash in it (power_meter-thing) out of filesingle. I cannot query this metric appropriately as I get these errors:

Error 4: "query_select_1: The 'power_meter' attribute was not found in any schema in the 'from' clause.

or if I put quotes (double or single) around the metric:

Error 8: "query_select_1: Expected 'select', 'from', 'where', or 'order_by', but found 'power_meter-thing'"

We really need some documentation around query capabilities for DSOS. I'm not sure what the 'dash' is used for in the query language but putting logic to accept quotes or some syntax around a metric to prevent this issue seems reasonable.
