How to convert date time format in SQL Server 2014 - sql-server

I'm using this query
SELECT convert(nvarchar(MAX), GETDATE(), 22) AS Date
Result: 08/05/16 12:23:08 PM
But I want result like this 8/5/2016 12:23:08 PM
dd/mm/yyyy hh:mm:ss a

As of SQL Server 2012 the FORMAT function is available allowing you to specify the format of data types and is locale-aware so it will consider date formatting in relation to the session's language or optional culture parameter.
You can achieve your custom formatting like so: FORMAT(GETDATE(), 'd/M/yyyy hh:mm:ss tt')
Note your requested format dd/mm/yyyy hh:mm:ss a is incorrect as in the case of single digits you want to remove zero padding i.e. 10/8/2016 not 10/08/2016. That's why in the format string I use only d and M.
Also, pay attention to #GarethD comment about the cost on larger datasets.

You could use the FORMAT function in T-SQL : https://msdn.microsoft.com/en-us/library/hh213505(v=sql.120).aspx
Here is the code :
SELECT FORMAT(GETDATE(), 'd/M/yyyy hh:mm:ss tt')

How to create query with format date DD-MM-YYYY

I have query database like this:
SELECT * FROM TABLE WHERE start_date = '01-10-2016' //DD-MM-YYYY
But above code error and actually in database date format is YYYY-MM-DD.
So how to create query with format date DD-MM-YYYY?
A proper date column (data type date !) has no format. Then it's enough to get your data input for a date column right, use to_date() for non-standard input format like #Shiva posted. Or better yet, always provide date literals in ISO 8601 format 'YYYY-MM-DD' to begin with, which works with any locale setting.
If you are running a broken design with dates stored as text, then combine to_date() and to_char() to transform any valid date format into any other text format:
SELECT * FROM tbl
WHERE start_date = to_char(to_date('01-10-2016', 'DD-MM-YYYY'), 'YYYY-MM-DD');
May be you can use to_date function to convert the above format into the standard format.
For instance,
SELECT to_date('01-10-2016', 'DD-MM-YYYY');

How to extract datetime string SQL Server?

I want a datetime string till minute from Datetime in sql server. Means I want to extract string after minute from Datetime from sql server.
Like: 2011-11-02 13:35:14.613
and I want this from above datetime string -
2011-11-02 13:35
Try this, will give you the date in format yyyy-mm-dd hh:mm as a string.
SELECT CONVERT(CHAR(16),'2011-11-02 13:35:14.613',120)
You can use your column name instead of the static date.
Your problem is a bit tricky, because the default formats which CONVERT() offers do not match your expected output. However, format style 120 has the following format:
yyyy-mm-dd hh:mm:ss
This is almost what you want, minus the :ss at the end. To get rid of that, you can just SUBSTRING() it off after calling CONVERT():
SELECT SUBSTRING(CONVERT(VARCHAR, yourDateColumn, 120), 1, 16)

T-SQL filtering by date in dd/mm/yyy format

In T-SQL is there a way to filter by greater than a date given in dd/mm/yyyy format?
so for example:
SELECT BIRTHDAY FROM ATABLE WHERE BIRTHDAY > 12/12/1990
Since many date formats are dependent on language & regional settings, I recommend to always use the ISO-8601 format of YYYYMMDD - and of course, also put your date literal into single quotes:
SELECT Birthday
FROM dbo.ATable
WHERE Birtday > '19901212'
This works on all SQL Servers - regardless of what language, date and regional settings you have

SQL Server date Format user dependent?

I have a query with hard coded dates, in this format
startdate >= '2012-11-03' AND enddate <= '2012-11-30 23:59'
My database date format is 'mdy', however I'm sure it will accept yyyy-mm-dd as its the universal date structure.
When I try run this query in SSMS on my target DB connected with a specific database user (userX) I get an error about the date formats
Msg 242, Level 16, State 3, Line 1
The conversion of a varchar data type to a datetime data type resulted in an out-of-range value.
However, when I run the exact query connected as the SA user, the query executes..
Why is this? I have given userX full dbo permissions (sysadmin etc) and still get the error?
If you need to specify datetimes using strings, you should use a safe, language-independent format.
In SQL Server, that's the ISO-8601 format (slightly adapted), and it supports basically two safe formats for DATETIME that always work - regardless of your language, regional and dateformat settings:
YYYYMMDD (e.g. 20121231 for 31st of December 2012) if you need date only
YYYY-MM-DDTHH:mm:ss (e.g. 2012-12-31T21:05:00 for 31st of December 2012, 9:05pm)
Note:
the first date-only format has no dashes or delimiters!
the second format has dashes for the date (can be omitted, too), and there's a fixed T as delimiter between the date and the time portion of the string
Update: as per your last comment (on the different default languages for the two users) - try this:
-- this is how your `SA` interprets the string as datetime....
SET LANGUAGE english
SELECT CAST('2012-11-30 23:59' AS DATETIME)
Works just fine...
-- this is how your British user interprets teh string as datetime
SET LANGUAGE british
SELECT CAST('2012-11-30 23:59' AS DATETIME)
Msg 242, Level 16, State 3, Line 7
The conversion of a varchar data type to a datetime data type resulted in an out-of-range value.
This tries to interpret the string as 11th of the 30th month of 2012 and obviously, that fails....
consider using
startdate >= '2012-11-03' AND enddate < '2012-12-01'
instead

How to make SQL Server to save datetime with AM/PM format?

I'm trying to make my SQL Server table datetime columns save datetime with AM/PM. How to make SQL Server to save datetime with AM/PM format?
Right now it saves date like this: 2012-01-23 14:47:00.000
Is it possible to save it 2012-01-23 02:47:00.000 PM ??
Or does SQL Server save the date and time in this format (2012-01-23 14:47:00.000) all the time and I need to convert it just on output and input?
Is it even possible to save it in this format (2012-01-23 02:47:00.000 PM)? Or does SQL Server save datetime in 24 hour format?
thanks indeed for any help. sorry for language. ;)
Internally the date and time are stored as a number.
Whether it's displayed in a 12 or 24 hour clock is up to the program formatting it for display.
As Andrew said, Datetime format is stored not as string. so, you can use CONVERT function to get the datetime value in approprate format. for example,
SELECT CONVERT(VARCHAR(20), GETDATE(), 100)
to learn more about datetime formatting, see this article
AM/PM serves only for visualization, if you need to display them, use CONVERT keyword:
SELECT CONVERT(varchar, YourDateTimeField, 109)
FROM YourTable
If you need to store AM/PM - it is makes no sense for datetime type, use varchar type instead.
You can simply use CONVERT function as following:
select CONVERT(VARCHAR,GETDATE(),108)
http://www.fmsinc.com/free/NewTips/SQL/AM_PM_time_format_in_SQL.asp

http://blogs.msdn.com/b/kathykam/archive/2006/09/29/773041.aspx
Depending on the accuracy of the datetime you are storing you might be able to clean it up with
REPLACE(CONVERT (varchar, YourDateTimeField, 109), ':00.0000000', ' ')
This will not work if your date field is populated with GETDATE() as that means it will contain seconds and milliseconds but it will work if the field is populated by a user and seconds and milliseconds are all zeros
