Assuming sql server, here is the convert documentation:

Looking through that, it looks like you want style 103:

仔细看看,看起来你想要样式 103:

 SELECT CONVERT(nvarchar(10), getdate(), 103)

回答by AlexCuse

This should help. It contains all (or most anyway) the different date formats

这应该有帮助。它包含所有(或大部分)不同的日期格式

I think you'd be better off handling the string conversion in client if possible.

如果可能的话,我认为你最好在客户端处理字符串转换。

回答by Ema.H

You can convert a date in many formats, in your case :

您可以将日期转换为多种格式,在您的情况下:

CONVERT(NVARCHAR(10), YOUR_DATE_TIME, 103) => 15/09/2016
CONVERT(NVARCHAR(10), YOUR_DATE_TIME, 3) => 15/09/16

Syntaxe :

语法:

CONVERT('TheDataTypeYouWant', 'TheDateToConvert', 'TheCodeForFormating' * )

The code is an integer, here 3 is the third formating without century, if you want the century just change the code to 103.

代码是一个整数,这里的 3 是没有世纪的第三个格式,如果你想要世纪,只需将代码更改为 103。
