如何检查混合日期格式的月和日顺序？

Question

There's column which contains date in different formats (ie. YYYY-MM-DD or YYYY-DD-MM ).

When I query it with format time:date, it throw an error: date/time field value out of range: "2022-23-02"

How can i solve it?

How can I check if it's YYYY-MM-DD or YYYY-DD-MM or another?

Answer 1

If you have no field that tells you whether it's YYYY-DD-MM or YYYY-MM-DD, you are kinda out of luck because it's possible that a value could be valid in both formats.

If you are able to redesign, and you must store the date as a string then use YYYY-MM-DD as it's easier for sorting. Optimally, just pass a JavaScript Date object to field of type date , timestamp , or timestampz to the database driver or orm and let it handle the conversion for you. Here's an example with node-postgres: https://node-postgres.com/features/types (the section labeled "date / timestamp / timestamptz")
