Oracle sql 开发人员日期/月份数据提取查询和语法

Question

I Want to extract data from a table for monthwise in oracle sql. I tried it as follow, SELECT * From customer ct Where ct. Application_signed _date in (Date '31-12-2020, Date '01-10-2020')

But i am unable to Fetch the data for this range, whereas data is available for this months.

Answer 1

The correct format for a date in Oracle -- and almost everywhere else -- is YYYY-MM-DD:

select *
From customer ct 
where ct.Application_signed_date in (Date '2020-12-31, Date '2020-10-01')

Note that Oracle dates can have time components. If that is possible in your data, then one fix is:

where trunc(ct.Application_signed_date) in (Date '2020-12-31, Date '2020-10-01')
