Question

有没有办法可以更好地写出来？它当前编写的方式需要很长时间来提取数据。数据的结果也重复数据具有相同信息的多行。有什么建议？我尝试更改了join子句，但这并没有多大帮助。我不知道还能用什么来缩短查询，使其运行更顺畅，并获得更好的结果。

Answer 1

如果不了解您的表格和数据，很难说。

它可能更好（如果仅为了可读性）不混合你的连接方法，所以我将内连接转换为

inner join cr_workupproc on cr_workupproc.FK_SOCRD_ID=patient.SOCRD_ID

和CR_DISEASE_HISTORY.FK_SOCRD_ID

查询中唯一的过滤器是

and PT_STUDY=3

但是pt_study似乎是一个表，或者这也是某个表上的一列？如果是这样的话，最好明确表明它与表限定符的位置。

如果这不是cr_imaging表上的列，那么您可能需要检查表顺序，因为您可能正在进行多次全表扫描。

此外，您应该获得查询的解释计划，以查看它正在做什么，这可以帮助您优化查询。

可以简化此Oracle SQL查询吗？
