甲骨文 - 增值
Oracle - Increment value
我有一个 table 持有客户发票数据。我试图通过创建结转计数器来查找客户发票上特定交易类型的相应月数。如果交易不再存在，计数器应重置为零。

它使用与原始解决方案非常相似的概念，除了将零或非零检查 transaction_count 添加到最终 sum() 分析函数的 partition by 子句中，我们不再需要输出 0 或总和的 case 语句。
希望您能告诉我我必须进行哪些调整 - 基本上，transaction_id 的检查是 null/not null 必须更改为 transaction_count = 0/!= 0，加上 row_number() 到 sum(transaction_count) 的更改，加上上述对 partition by 子句的更改。我敢肯定，如果您再考虑一下，就会得出相同的结论，如果您还没有的话！ *{:-)
