WHERE condition examples

Everything I have seen on thwack regarding example queries have been pretty plain vanilla, so I thought I would provide a couple WHERE clauses I have found to be fairly helpful. Please feel free to add.

SELECT ServiceTag FROM Orion.HardwareHealth.HardwareInfo WHERE NodeID = 238 OR NodeID = 239

SELECT NodeID,SysName,Vendor,MachineType,IOSImage,IOSVersion,IP FROM Orion.Nodes WHERE Vendor LIKE '%Cisco%'
