sql - Getting Table Results based on a Start and End Date using a single date

Question

Currently I am having trouble trying to query a data set that contains multiple records for unique customers. Each row has a start date and end date and the most recent record marked as Most Current and end date as 12/31/9999. I am trying to write a query so that I can return all records that fall on a specific date such as months end (10/31/2018). My goal in Oracle SQL Developer is to type in all records/data on the day 10/31/2017 so the rows with the * are the only ones Id want back. The final outcome is to do this with a much larger file and see the entire year at months end where each person was at based on the month end date for 1 year.

Answer 1

我认为您想列出截至指定日期的所有最新记录。为此，我只需使用 BETWEEN 条件：

select * from mytable
where date'2017-31-10' between start and end

Answer 2

你能详细说明你期望的输出吗？我可以看到您正在尝试在这里实现时间功能。如果这符合您的目的，请检查此链接 Oracle temporal 。至于突出显示的记录，您可以像这样在 where 子句中使用简单的条件，并根据需要格式化日期部分：

select * from emp where  endd=to_date('9999/12/31','yyyy/mm/dd')
