如何在PostgreSQL中两次显示今天的日期

Question

SELECT TO_CHAR(now() :: DATE, 'dd/mm/yyyy');

The above query displays only once.

I want to display the above date twice or more.

Answer 1

If you want to display the same date twice side to side, just query it twice:

SELECT TO_CHAR(now()::DATE, 'dd/mm/yyyy'), TO_CHAR(now()::DATE, 'dd/mm/yyyy');

If you want to display multiple rows, you can use a set-generating function, such as generate_series :

SELECT TO_CHAR(now()::DATE, 'dd/mm/yyyy')
FROM   GENERATE_SERIES(1, 2)
