[Vtigercrm-developers] Query issue

[Joe Bordes]

This join is for the "member of" field. So if you don't use this field 
you should be ok.
It is possible that other parts of the code that use this query be affected.
I would suggest you try adding an index on parentid instead of 
eliminating the join
Let us know how it goes.
