如何检查日期时间列之间的日期时间

Question

How to check the Datetime between the Datetime columns?

For example:

Column1             Column2         Price
------------------------------------------
01/05/2019          31/06/2019        50
01/07/2019          31/09/2019        49
01/10/2019          31/12/2019        48
01/01/2020          31/01/2020        45

Now, how can I send Price based on dates?

If today date is 01/06/2019 then we will send the price as 50 or today's date is 25/01/2020 then we will send 45 like that.

How can I do this query?

Answer 1

Just use

SELECT Price FROM [TableName] WHERE GETDATE() BETWEEN Column1 AND Column2

As long as the Date columns do not overlap and reflect 1 price for each given period.

In Oracle use CURRENT_DATE instead of GETDATE()
