在OLTP数据库事务的主要触发代码中找到:

-- This line negates the @inverseqty, which is the
-- negative of the @insertedquantity.  This works through the
-- magic of the trigger.  In fact, this code is a lot like
-- the bermuda triangle!
@negquantity = -1 * @inverseqty

来自Apache Xalan源代码:

/**
 * As Gregor Samsa awoke one morning from uneasy dreams he found himself
 * transformed in his bed into a gigantic insect. He was lying on his hard,
 * as it were armour plated, back, and if he lifted his head a little he
 * could see his big, brown belly divided into stiff, arched segments, on
 * top of which the bed quilt could hardly keep in position and was about
 * to slide off completely. His numerous legs, which were pitifully thin
 * compared to the rest of his bulk, waved helplessly before his eyes.
 * "What has happened to me?", he thought. It was no dream....
