Group by 'other', where groups with small contribution are included in 'other' field - MySQL -


I would like to group through an item in my table, which has an affiliate monetary value. I can work as a percentage of this, although there are a lot of things in the list (many are useful, for example in a graph) As a result, I would like to keep those items which are 5% in an 'other' group Have less ideas in lesser stories, any ideas?

It seems as if a union can help, like (dependent) How to organize your table, definitely): 

  item item is itemized as item number, SUM (percentage), item by item item type (percent) > = 0.05 Select the union from the 'Other' items in the item group (*) (*) (*) from SAM (*) SIM (percent) HIPIT item typing Sam (percent) <0.045)  < / Pre> 
 if you There is no percentage area but only (say to say) a value field (so% is dynamically calculated as equivalent to 100 times the value of an item) You can get a grand total from another nested SELECT But, at some point it may be worth the change in procedural approaches, as the other responder signs.
