问题 The issue is that using to_char will turn order by date into order by ascii. Example: SELECT foo, bar FROM baz ORDER BY foo; I would like to format foo using to_char, but doing this will affect the order: SELECT to_char(foo,'dd/MM/yyyy') as foo, bar FROM baz ORDER BY foo; Because foo now is of type text. There is a way to correctly do this? Or only in the code? 回答1: You can use a different alias for the formatted column: SELECT to_char(foo,'dd/MM/yyyy') as formatted_foo, bar FROM baz ORDER BY

The problem is, the condition works in react native development mode and not working in react native production release. I am using firebase for the database, also using redux. Here is my code: var d = new Date(); const fromDate = extract.validFrom.split("-").reverse(); //"01-02-2019" const tillDate = extract.validTill.split("-").reverse(); //"10-03-2019" var k = new Date
