早上的人，
我在使用COALESCE时遇到了一个问题，导致存储过程将数据写入表中而过度运行。 （没有COALESCE需要4分钟，需要1小时30分钟才能完成。）
我需要这个临时表的f_列清除NULL，因为这些将在稍后的仓库中用于演算，然后显示给Cognos报表工作室。
有161列需要这个，而且我也尝试过“当X X为0，而不是X ELSE时的情况”，这显然影响较小但仍需要一个半小时。
还为没有欢乐的表格添加了“DEFAULT 0”。
存储过程如下（事先告知它的大小）

首先，您可以尝试 ISNULL ，它具有更好的性能（但不是您需要的更多），但它更快。
以下是旧StackOverlow线程的参考：Which is quicker COALESCE OR ISNULL?
更新：
这意味着性能的巨大差异：
“Marcus Culver：在ISNULL的行列中，共有730,000行，其中有一列是00:02:34 反对在01:32:43聚结“
