SQL 查询以从日期获取季度和 month/year

Question

在一列中我有日期 - 01-02-2022, 01-03-2022

我怎样才能得到下面格式的这个

ABS_DATE                    Quarter            Month 
01-02-2022                  Q1 2022             02/2022
30-03-2021                  Q1 2021             03/2021
29-12-2020                  Q4 2020             12/2020

Answer 1

您可以使用the to_char() function to convert your dates to whatever format您需要的，包括宿舍：

to_char(abs_date, 'DD-MM-YYYY') as abs_date
to_char(abs_date, '"Q"Q YYYY') as quarter
to_char(abs_date, 'MM/YYYY') as month

带引号的 "Q" 是 a character literal，不要与未带引号的 Q 混淆，后者是“Quarter of year”的元素。

使用 CTE 获取示例数据的演示：

with your_table (abs_date) as (
  select date '2022-02-01' from dual
  union all
  select date '2021-03-30' from dual
  union all
  select date '2020-12-29' from dual
)
select abs_date as raw_date,
  to_char(abs_date, 'DD-MM-YYYY') as abs_date,
  to_char(abs_date, '"Q"Q YYYY') as quarter,
  to_char(abs_date, 'MM/YYYY') as month
from your_table

RAW_DATE	ABS_DATE	QUARTER	MONTH
01-FEB-22	01-02-2022	Q1 2022	02/2022
30-MAR-21	30-03-2021	Q1 2021	03/2021
29-DEC-20	29-12-2020	Q4 2020	12/2020
