CAS Dos and Don’ts
				• Do not submit a query unless you have some idea how long it will take! – It could tie up the server for hours (even days)! – Use “select count(*)” or “select top 10” instead – Or try “quick” first, to see if it can be done quickly • Do use predefined views for commonly-used objects and parameters – PhotoObj, PhotoPrimary for photometry – PhotoTag if you only need popular fields – SpecObj for spectra
