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
