Question

我正在处理一个分析两条记录的查询，并检查一条记录是否与第二条记录匹配。如果记录1列匹配记录2列，则没有错误。如果记录1列与记录2列不匹配则存在错误。我希望能够计算每个YPID的错误。对于我的生活......我无法弄明白。救命啊！

这是我的疑问：

Answer 1

我猜你需要使用LEAD，LAG功能。

点击此链接http://oracle-base.com/articles/misc/lag-lead-analytic-functions.php

LAG功能用于访问前一行的数据 LEAD函数用于从下一行返回数据。

通过这个你可以比较第一行和第二行

计算case语句生成的结果
