我在更新某些记录时犯了一个错误，需要一些帮助来“恢复”它们。我以下数据，我需要EC和INVOICE_NUM KEYWORDs来获得一个迭代器后缀，如下面所示的所需结果。
如何遍历所有记录并为每个具有＆gt;的RID执行此操作EC和INVOICE_NUM KEYWORD的值是1吗？如果只有一个EC或INVOICE_NUM，则不需要更新，它可以保留为EC或INVOICE_NUM。

[edit]根据以下内容进行了更新。并更好地匹配预期结果[/ edit]
WITH子句只是创建您的数据......您可以将其保留并将“从w_data”更改为您的表格。
内部查询只是抓取数据并计算不同关键字的每个“组”中出现的次数。
外部查询使用CASE仅在计数器上添加EVENT_CODE和INVOICE_NUMBER。 那里的新列为每个组使用row_number并将它们全部切片。
您可以将该查询返回到MERGE语句中以获得最简单的更新方式：
