How to get Time from DateTime format in SQL?

问题

I want to get only Time from DateTime column using SQL query using SQL Server 2005 and 2008 Default output:

AttDate                   
==
2011-02-09 13:09:00    
2011-02-09 14:10:00

I'd like this output:

AttDate                Time 
==
2011-02-09 13:09:00    13:09
2011-02-09 14:10:00    14:10

回答1:

SQL Server 2008:

select cast(AttDate as time) [time]
from yourtable

Earlier versions:

select convert(char(5), AttDate, 108) [time]
from yourtable

回答2:

Assuming Sql server

SELECT CONVERT(VARCHAR(8),GETDATE(),108)

回答3:

SQL Server 2008+ has a "time" datatype

SELECT 
    ..., CAST(MyDateTimeCol AS time)
FROM
   ...

For older versions, without varchar conversions

SELECT 
    ..., DATEADD(dd, DATEDIFF(dd, MyDateTimeCol, 0), MyDateTimeCol)
FROM
   ...

回答4:

The simplest way to get the time from datetime without millisecond stack is:

SELECT convert(time(0),getDate())

回答5:

Try using this

Date to Time
```
select cast(getdate() as time(0))
```
Time to TinyTime
```
select cast(orig_time as time(0))
```

回答6:

Try this:

select  convert(nvarchar,CAST(getdate()as time),100)

回答7:

Try this, it will work:

CONVERT(VARCHAR(8),DATETIME,114)

For your reference.

回答8:

select AttDate,convert(char(5), AttDate, 108) [Time] from yourTableName

回答9:

select cast (as time(0))

would be a good clause. For example:

(select cast(start_date as time(0))) AS 'START TIME'

回答10:

I often use this script to get Time from DateTime:

SELECT CONVERT(VARCHAR(9),RIGHT(YOURCOLUMN_DATETIME,9),108) FROM YOURTABLE

回答11:

To get the time from datetime, we can use

SELECT CONVERT(VARCHAR(20), GETDATE(), 114)

回答12:

If you want date something in this style: Oct 23 2013 10:30AM

Use this

SELECT CONVERT(NVARCHAR(30),getdate(), 100)

convert() method takes 3 parameters

datatype
Column/Value
Style: Available styles are from 100 to 114. You can choose within range from. Choose one by one to change the date format.

回答13:

Get date of server

SELECT LTRIM(RIGHT(CONVERT(VARCHAR(20), GETDATE(), 100), 7)) FROM TABLENAME WHERE ...

If it is stored in the table

SELECT LTRIM(RIGHT(CONVERT(VARCHAR(20), datename, 100), 7)) FROM TABLENAME WHERE ...

Result:

11:41AM

回答14:

select convert(char(5), tbl_CustomerBooking.CheckInTime, 108) AS [time]
from tbl_CustomerBooking

回答15:

select substr(to_char(colUmn_name, 'DD/MM/RRRR HH:MM:SS'),11,19) from table_name;

Output: from

05:11:26
05:11:24
05:11:24
