Sql 如何使用下面的代码获取一行中的数据

我想在这里通过保持相应的patient_id iam在1行中获取数据来获取1行中的数据，但如果我通过给出函数的输入参数来执行，则patient_id iam数据将插入ams.ams_trans_integration_events表中，共4行

elsif（\u集成\u类型=34）然后/患者注册/

我在ams.ams\u trans\u integration\u事件表中插入了4行，如下所示，但我只需要插入1行，这是最后一行

你想得到四行中的哪一行？。实际上我是这样得到四行的如果你得到的是相同的四行，在

SELECT

no之后添加

DISTINCT

，我的所有4行数据都不同，但我只希望最后一行数据出现，所以在where？中定义相应的子句。四行中您希望得到哪一行？。实际上，如果得到的是4行相同的数据，我会得到4行，在
