Re: Optimize Query with SUM() and CASE... statements
What you are trying to accomplish with your CASE statements since they test different columns for a value - not a single column for various values? I'm not quite sure which would be effective in a given situation, likely the first 'true' clause - which may not be what you want.
You can improve performance by having good indexes on all the WHERE columns that are available for a user to select.
