Are there any ways to store the datetime type that goes outside of the type range? I mean if i try to do smth likeINSERT INTO [tbl](..., [IndependenceDate],....) VALUES(...,'1650-01-01',...) i will get an error.(cause datetime type range is: January 1, 1753, through December 31, 9999). I am using SQL Server Management Studio.
You can use Date if you don't care about the time and have a newer version of SQL. Alternatively you can use DateTime2 (but this will use more space)...

I created a small script that works in SQL Server Management Studio, then I created a SQL Server Agent job with that same script; but after I run it, I get an error:
The conversation of a varchar data type to a datetime data type resulted in an out-of-range
I fixed the problem by change the format of date to ISO 8601, but I don't release how my first script works on SSMS and not in SQL Server Agent.
First script:
declare #teste datetime
set #teste = '31/12/2099 00:00:00'
select #teste
Fix error:
declare #teste datetime
set #teste = '20991231 00:00:00'
select #teste
This is one reason why using unambiguous formats are so important when using date(time) datatypes. The only formats that an unambgious in SQL Server, regardless of language and datatype are the formats yyyyMMdd and yyyy-MM-ddThh:mm:ss.
For the date '31/12/2099 00:00:00' and the language your Login is using it appears that SQL Server is interpreting the value as the 12th day, of the 31st month, of the year 2099. There aren't 31 months in the year, and hence the error. (DB<>Fiddle). It's worth noting that date (and the other "new" datetime data types) behave differently and also can unambiguously understand the format yyyy-MM-dd; notice in this DB<>fiddle the difference in the values for the datetime values simply due to the language setting.
As you can see, the solution is to use a unambiguous format. So, as you're using a date and time, I would suggest the string '2099-12-31T00:00:00'.
In my aplication I use a DateEdit control and show the date using this format dd/MM/yyyy so the date is save correctly when I use mssql-server 2014 (spanish) but whe I use mssql-server 2008 (english) the date is stored with this fomat MM/dd/yyyy so what I need to know is if there is a way to store the date with the format dd/MM/yyyy no matter the versión of mssql-server I use or the lenguage I use?
EDIT: to explain better this is the problem, this text 03/07/2017 is stored in the sqlserver 2014 as july 3 of 2017 and in the sqlserver 2008 is stored as march 7 of 2017.
Convert.ToDateTime(String).ToString("dd-MM-yyyy")
Check the defualt language on your MS SQL Server 2008, and if its possible, you can change to Spanish: How to change Date Format after installing SQL Server
Also, you can format your query output with the CONVERT function (#ZLK post the link) using the format 103: CONVERT (DATETIME,[YOURDATE],103)
Following solution has two options. You can use one as per your requirements.
DECLARE #Date AS TABLE(val VARCHAR(30));
INSERT INTO #Date VALUES('12/04/2016');
INSERT INTO #Date VALUES('10/01/2015');
INSERT INTO #Date VALUES('17/03/2017');
--Option 1
SELECT TRY_PARSE(val AS DATE USING 'en-gb') 'Option 1' FROM #Date;
--Option 2
SELECT CONVERT(VARCHAR(10),TRY_PARSE(val AS DATE USING 'en-gb'),103) 'Option 2' FROM #Date;
And the outputs are:
As others said: SQL doe not store dates as we humans do. But thats another matter.
I think what you need is to inform SQL the format your date has.
The best option is to use ISO 8601 format: yyyy-mm-ddThh:mi:ss.mmm.
So, if before saving the date you just format it with this format, SQL (no matter the version or the language) will recognize it as begining with a year, followed by a month and so on. The key of this subject is using first 4 digits.
This way, 2017-01-03 will always be January 03, 2017 and never March 01, 2017. Hope this help you.
Using this you can change the date Format
select FORMAT(GETDATE(), 'dd/MMM/yyyy', 'en-us')
if any date time value provided to sql server can i get it's midnight value with some function in sql server.. for example if i provide 2013/07/03 01:34AM , i want to get it to 2013/07/03 12:00 AM.Is there a way to do it?
SQL Server 2008+
SELECT CAST(CAST('2013/07/03 01:34AM' AS date) AS datetime)
For older versions, see this Best approach to remove time part of datetime in SQL Server Never use anything that requires float or int or varchar conversions
This should give you what you need:
SELECT DATEADD(DAY, DATEDIFF(DAY, 0, InputDateField), 0)
Should be slightly quicker than cast:
Most efficient way in SQL Server to get date from date+time?
I'm currently using
Convert(varchar, Getdate(), 101)
to insert only date part of system date into one of my sql server database tables.
my question is: is it the right way to do that or is there any other better method to do it?
I don't understand why you're converting the GETDATE() output (which is DATETIME already) to a VARCHAR and then SQL Server would convert it back to DATETIME upon inserting it again.
Just use:
INSERT INTO dbo.YourTable(SomeDateTimeColumn)
VALUES(GETDATE())
If you're doing that conversion to get rid of the time portion of the DATETIME, you should better:
use the DATE datatype (available in SQL Server 2008 and newer) to store only the DATE (no time)
if you're using SQL Server 2005 or earlier, use this conversion instead - should be much more efficient than two conversions!
INSERT INTO dbo.YourTable(SomeDateTimeColumn)
VALUES(DATEADD(dd, DATEDIFF(dd, 0, GETDATE()), 0))
Update: did some performance testing, and in this particular case, it seems the amount of work that SQL Server needs to do is really the same - regardless of whether you're using the convert to varchar stripping the time and back to datetime approach that you already have, or whether you're using my get the number of days since date 0 approach. Doesn't seem to make a difference in the end.
The BEST solution however would still be: if you only need the date anyway - use a column of type DATE (in SQL Server 2008 and newer) and save yourself any conversions or manipulations of the GETDATE() output altogether.
Surely there is a way to store a date value prior than 1-1-1900 in a column other than varchar? Or do I really have to break this out, and perform my own datetime library for date differences, sorting, and such?
Yes, I understand how datetime's are actually stored (an integer value from a specific date), but I remember there being another workaround from years ago. It's just slipping me now.

Yes the SQL Server DateTime type can store dates from 1 January 1753.
SQL Server 2008 has the DATE data type which can range from 0001-01-01 through 9999-12-31.
With previous versions, your SOL if you need a date prior to 1753-01-01 (Minimum value for DATETIME).
