Without knowing what it is you're trying to accomplish I can only speculate. The query below will return the historical values for component ID #76. I would recommend using either the Win32 Report Writer available under [Start -> Programs -> SolarWinds Orion -> Alerting, Reporting, and Mapping -> Report Writer] or the new Web Report Writer introduced in SAM 6.0 available under [Settings -> Manage Reports]
SELECT TOP 10000 APM_StatisticsUsage.AvgStatisticData AS Statistic_Data FROM APM_AlertsAndReportsData INNER JOIN APM_StatisticsUsage ON (APM_AlertsAndReportsData.ComponentId = APM_StatisticsUsage.ComponentID) WHERE ( DateTime BETWEEN 41579 AND 41610 ) AND ( (APM_AlertsAndReportsData.ComponentId = 76) )
