-- SQL to calculate a block's diffacc (difficulty accepted)
-- This should match the block's confirmed diffacc
--  i.e. when a block has statsconfirmed='Y'
-- If the block has any unaged sharesummaries,
--  the script will abort and report the count
-- Sharesummaries are aged at ~10 minutes after the next workinfo,
--  after the sharesummary's workinfo, was first generated
-- You need to set the block number at line 21 - hi := blockheight;
