how do I convert this:
DECLARE #FromDate varchar = 'Feb 2020'
to a Date like this
DD/MM/YYYY or DDMMYYYY
I need to sort some dates and from the combobox you can just choose those three : Dez 2019, Jan 2020 or Feb 2020.
So I thought I could do something like that:
DECLARE #FromDate varchar = 'Feb 2020';
SELECT RIGHT(convert(varchar, CONVERT(date, CONVERT(varchar, PIN_DATE)), 106),8)
FROM PIN
WHERE RIGHT(CONVERT(varchar, CONVERT(date, CONVERT(varchar, PIN_DATE)), 106),8)
= CONVERT(datetime, #FromDate,106)
The date in PIN_DATE looks like this : YYYYMMDD aka. 20201231
This is an ERROR:
DECLARE #FromDate varchar = 'Feb 2020'
This assigns #FromDate as a SINGLE character, so the value is 'F'.
When using the character types in SQL Server, always use a length:
DECLARE #FromDate varchar(255) = 'Feb 2020'

I have data where a date is stored as text, for example:
Jan 01, 2001
I see a number of examples showing how to format a datetime to this format but I'm looking for a function to change it back to a date.
What is even more confusing is what I tried gives me "2020-01-01." Any suggestions?
DECLARE #d varchar(10) = 'Jan 01, 2001'
SELECT TRY_CONVERT(date, #d)
I'm using SQL Server 2014.
Your string is not long enough. Declare it with a long-enough length:
DECLARE #d varchar(255) = 'Jan 01, 2001';
SELECT TRY_CONVERT(date, #d);
If you show the value of #d, you will see what this code returns:
DECLARE #d varchar(10) = 'Jan 01, 2001';
SELECT #d, TRY_CONVERT(date, #d);
which is 'Jan 01, 20'. SQL Server interprets that as 2020.
I have a varchar column which has values like "Aug 07 2017, 04:14 AM,EDT".
I need to convert this to a date column so that its possible to take the maximum value of the date.
I tried this:
select CONVERT(datetime, #dateField, 108)
from table
But I am getting the following error:
Conversion failed when converting date and/or time from character string.
You can just use left() and convert():
select convert(date, left('Aug 07 2017, 04:14 AM,EDT', 11))
If you want a datetime then convert the date and time separately, then:
select ( convert(datetime,
left('Aug 07 2017, 04:14 AM,EDT', 11)
) +
convert(datetime,
convert(time,
substring('Aug 07 2017, 04:14 AM,EDT', 14, 8)
)
)
)
Note: This is not taking the time zone into account.
Better Datetime solution
DECLARE #dateField AS NVARCHAR(50) = 'Aug 07 2017, 04:14,EDT'
-- Get index of last comma
DECLARE #validDateField AS NVARCHAR(20) = REPLACE(LEFT(#dateField, LEN(#dateField)- CHARINDEX(',', reverse(#dateField))), ',','')
SELECT CONVERT(DATETIME, #validDateField, 108)
Here is a solution:
select CONVERT(datetime, REPLACE(LEFT(#dateField, LEN(#dateField) - 3),',','') ,108 )
I'm passing a start date and end date parameter to my stored procedure. I'm doing a simple test here:
DECLARE #StartDate DATE = '10/06/2013' --dd/mm/yyyy
SELECT #StartDate -- this statement running successfully
DECLARE #EndDate DATE = '30/06/2013' --dd/mm/yyyy
SELECT #EndDate -- this statement giving error
This statement returns the following error
Msg 241, Level 16, State 1, Line 2
Conversion failed when converting date and/or time from character string.
Does anybody have idea what's going wrong with EndDate?
I'm pretty sure the error is on this line:
DECLARE #EndDate DATE = '30/06/2013' --dd/mm/yyyy
Not on the SELECT. It wouldn't make sense that it would be on the SELECT, because processing a variable should be fine.
I would recommend that you use YYYYMMDD formats. The following is my preference:
DECLARE #EndDate DATE = '2013-30-06' ;
However, it can fail for certain internationalization settings. The following is documented to always work:
DECLARE #EndDate DATE = '20133006' ;
'10/06/2013' means 06-Oct-2013 not 10-Jun-2013. There is nothing exists with month 30 as in your #EndDate '30/06/2013'.
DECLARE #StartDate DATE='10/06/2013'
DECLARE #DummyDate DATE = '2013-Oct-06'
IF #StartDate = #DummyDate
BEGIN
SELECT 1
END
By default sql server takes date value in 'yyyy-mm-dd' format,
So you need to follow that format or you need to convert date format accordingly.
T-SQL convert string to datetime - SQL Server convert string to date

I have a table which has a datetime column. I want to show date in date-month-year forma.I am using SQL Server 2008.
You need to convert datetime column
select convert(varchar,datecolumn,103) from yourtable
Some datetime convertions:
SELECT convert(datetime, '10/23/2016', 101) -- mm/dd/yyyy
SELECT convert(datetime, '2016.10.23', 102) -- yyyy.mm.dd
SELECT convert(datetime, '23/10/2016', 103) -- dd/mm/yyyy
SELECT convert(datetime, '23.10.2016', 104) -- dd.mm.yyyy
SELECT convert(datetime, '23-10-2016', 105) -- dd-mm-yyyy
SELECT CONVERT(VARCHAR(10), GETDATE(), 111) AS [YYYY/MM/DD]
/* YYYY/MM/DD
2015/07/11 */
SELECT CONVERT(VARCHAR(10), GETDATE(), 112) AS [YYYYMMDD]
/* YYYYMMDD
20150711 */
-- SQL convert date string to datetime - time set to 00:00:00.000 or 12:00AM
PRINT CONVERT(datetime,'07-10-2012',110) -- Jul 10 2012 12:00AM
PRINT CONVERT(datetime,'2012/07/10',111) -- Jul 10 2012 12:00AM
PRINT CONVERT(datetime,'20120710', 112) -- Jul 10 2012
You can learn all DateTime convertion from here
FORMAT can be used for this;
SELECT FORMAT(GETDATE(), 'dd-MM-yyyy') --20-09-2021
in your case;
SELECT FORMAT(datetime, 'dd-MM-yyyy') AS datetime --20-09-2021
Edit;
Sorry to inform that I've just seen you mentioned SQL Server 2008 this code works for SQL Server 2012 for those who use 2012 and ends up in here!
MySQL has a function called STR_TO_DATE, that converts a string to date.
Question:
Is there a similar function in SQL Server?
If you need to parse a particular format, use CONVERT(datetime, #mystring, #format). Use this as a reference: https://web.archive.org/web/20200729210252/http://www.sqlusa.com/bestpractices/datetimeconversion/
Some examples:
SELECT convert(datetime, '10/23/2016', 101) -- mm/dd/yyyy
SELECT convert(datetime, '2016.10.23', 102) -- yyyy.mm.dd ANSI date with century
SELECT convert(datetime, '23/10/2016', 103) -- dd/mm/yyyy
SELECT convert(datetime, '23.10.2016', 104) -- dd.mm.yyyy
SELECT convert(datetime, '23-10-2016', 105) -- dd-mm-yyyy
-- mon types are nondeterministic conversions, dependent on language setting
SELECT convert(datetime, '23 OCT 2016', 106) -- dd mon yyyy
SELECT convert(datetime, 'Oct 23, 2016', 107) -- mon dd, yyyy
-- 2016-10-23 00:00:00.000
SELECT convert(datetime, '20:10:44', 108) -- hh:mm:ss
-- 1900-01-01 20:10:44.000
What if the string is 7/7/2010?
Then use CONVERT with either 101 (mm/dd/yy) or 103 (dd/mm/yy) depending on what you want:
SELECT CONVERT(DATE, '7/7/2010', 103)
Result:
2010-07-07
CAST(<string> AS DATETIME)
Use CAST.
declare #MyString varchar(10)
declare #MyDate datetime
set #MyString = '2010-08-19'
set #MyDate = cast(#MyString as datetime)
select #MyDate
Here is a good example:
declare #myDate datetime
set #myDate = '06/09/2017'
select concat(convert(varchar(20), #myDate,101), ' -- ',
convert(varchar(20), #myDate,103), ' -- ',
convert(varchar(20), #myDate,6))
This is what you get, depending on 101 or 103 or 6:
09/06/2017 -- 06/09/2017 -- 06 Sep 17
A good summary of types of dates is here - https://www.w3schools.com/sql/func_convert.asp
On MSSQL:
select cast('2012/06/12 10:32AM' as datetime);
You will get it:
2012-06-12 10:32:00.000
