Rock Lapsed Giver SQL

lapsed_giver_rock.sql

-- Version 2.3.0

-- This SQL searches your Rock database for "recent lapsed givers". The definition of a recent lapsed giver is 
-- someone who gives $3,000 / yr, who has given less than $100 in the past 8 weeks, __who was giving normally this same 8-week period last year__.
-- That last clause is key, because many people give a lot, but can have 8 week non-giving periods. Maybe they take the summer off. Maybe the winter off.
-- Maybe they give a large amount in December, then don't start again til March. Without comparing their giving to the same 8-week period last year
-- it's hard to know.

-- You can tweak the varibles for your church below. Just change the 3000, 100, and 8

-- To turn this into a DataToolKit Plug SQL statement (see Rock Shop, you can use this plugin to turn the People you find on this list into a Dataview),
-- delete all the SELECT fields at the top except for p.[Id] (p.Nickname, p.Email, etc.)
