Sql 运行以下查询时出现“被零除错误”错误

我无法确定错误，因为我正在尝试运行此查询。它给了我除以零的误差。此错误发生在第1行

Msg 8134, Level 16, State 1, Line 1
Divide by zero error encountered.

有人能帮忙吗

据我所知，只有一个分母可以是零。其他的似乎是一个常数4

一种简单的捕捉可怕的被零除的技术是NullIf

例如，如果分母=0，则返回NULL

因此，在你的情况下：

NullIf(cast(sum(t.Total_tickets) as decimal(38,2)),0)

请不要使用不适用于您的问题的标签。如果没有实际数据，这是不可能回答的。但是，你会遇到很多分歧，所以这就是问题所在。尝试做一个案例陈述，如果分母为0，则输出为空。请不要使用不适用于您的问题的标记。如果没有实际数据，这是不可能回答的。但是，你会遇到很多分歧，所以这就是问题所在。尝试制作一个CASE语句，其中如果分母为0，则输出为空。这给了我以下错误：Msg 102，级别15，状态1，第30行“temp2”附近的语法不正确。@SankW-抱歉，还有一个编辑错误。。。底部有几行被切掉了。这给了我以下错误：Msg 102，级别15，状态1，第30行“temp2”附近的语法不正确。@SankW-对不起，还有一个编辑。。。底部有几行字被砍掉了。@SankW高兴吗helped@SankW很高兴它有帮助
