// attach simulation db master.attachDb(simulationFile, "SimDb");

const ecsql = SELECT ts.TimeFromStart [Time From Start (s)], p.UserLabel [Pipe with Max Flow], MAX(ltvrr.Flow) [Max Flow (L/s)] FROM SimDb.simrescore.TimeStep ts INNER JOIN SimDb.stmswrres.BasicFlowResultRecord ltvrr ON ts.ECInstanceId = ltvrr.TimeStep.Id INNER JOIN swrhyd.Pipe p ON p.ECInstanceId = ltvrr.ElementId GROUP BY ts.ECInstanceId HAVING MAX(ltvrr.Flow) > 1 LIMIT 3;

const reader = master.createQueryReader(ecsql); const rows = []; while (await reader.step()) { rows.push(reader.current.toRow()); } const expected = [ { 'Time From Start (s)': 0, 'Pipe with Max Flow': 'CO-4', 'Max Flow (L/s)': 66.14359584163114 }, { 'Time From Start (s)': 3600, 'Pipe with Max Flow': 'CO-4', 'Max Flow (L/s)': 78.33925707748288 }, { 'Time From Start (s)': 7200, 'Pipe with Max Flow': 'CO-3', 'Max Flow (L/s)': 85.32875334207684 }, ]; expect(rows).to.deep.equal(expected);
