om高余额低付款的租户，而低余额的租户由于某种原因支付了很高的付款。但您的系统可能有其他检查来防止这种情况。我有500-1200个租户，这些租户将保持不变，大约有140K笔交易，这些交易将随着时间的推移而增长。此查询每月只执行一次，因此n^2的增长率是可以接受的。ABS块只是将负变为正。它也保证为负数，因为该选项适用于0以下的所有金额。原始选项是。。。我只是在想，这些中间计算中的一些可能更加模糊，比如

ABS（CumulativeBalance-currentpayed）

（正如我所命名的那样）。你会从一个高余额和低付款的租户那里得到相同的数字，而一个低余额的租户由于某种原因支付了非常高的付款。但您的系统可能有其他检查来防止这种情况。
