SQL 转换为工作日和 hh:mm

Question

Not sure can we convert datetime field column, for example:

Contactdate
2020-03-12 16:20:34.000
2020-01-01 00:52:34.000

become

contact date
Wednesday 12:52
Thursday  04:20

Answer 1

DECLARE @d table(Contactdate datetime);

INSERT @d VALUES('2020-03-12 16:20:34.000'),('2020-01-01 00:52:34.000');

SELECT contact = DATENAME(WEEKDAY, Contactdate), 
       date    = CONVERT(CHAR(5), Contactdate, 108)
FROM @d;

I tend to stay away from FORMAT() - while convenient and flexible, it does not scale in my testing .

Answer 2

In SQL Server, you can use format() for this:

select format(contactdate, N'dddd hh\:mm') formated_date
from mytable

Demo on DB Fiddle :

select contactdate, format(contactdate, N'dddd hh\:mm') formated_date
from (values 
    (cast('2020-03-12 16:20:34.000' as datetime)), 
    (cast('2020-01-01 00:52:34.000' as datetime))
) as t(contactdate)

contactdate             | formated_date  
:---------------------- | :--------------
2020-03-12 16:20:34.000 | Thursday 04:20 
2020-01-01 00:52:34.000 | Wednesday 12:52
