I would like to convert varchar data to datetime format. So, can anyone let me know the way. this is the sample data available in column.
I tried following things
SELECT
CASE WHEN [EntryTime] = ''
THEN NULL
ELSE CONVERT(datetime2, [EntryTime])
END [EntryTime]
FROM
table
I get this result:
But, I don't need additional milliseconds.
So, can anyone let me know how should I convert it to a datetime format?
For all other tries, I am getting error as
Conversion failed when converting date and/or time from character string
So, can anyone please help me? Thanks.
specify the sub-second width as datetime2(7)
select
try_cast(EntryTime as datetime2(7)) by_try_cast
, try_convert(datetime2(7), EntryTime ) by_try_covert
I also suggest you use try_cast() or try_convert() if they are available, if not just remove "try_", The advantage of these is that if a string is an invalid date they return NULL and don't crash the query.
If you really don't want datetime2:
select cast(try_cast(EntryTime as datetime2(7)) as datetime)
see it: http://rextester.com/YWBB31287
LEFT and Concat (SQL2012+)/ or use standard concatenation
then Cast or Convert (for formatting)
declare #mytable as table (
entrytime varchar(100)
)
insert into #mytable
values ('2017-08-31 08:23:23'),
('2017-11-10 08:28:37.75000000'),
('2017-10-30 08:23:37.32000000')
select cast(left(concat(entrytime,'.000'),23) as datetime) from #mytable
Result
2017-08-31 08:23:23.000
2017-11-10 08:28:37.750
2017-10-30 08:23:37.320

I have a date stored as nvarchar which I cannot seem to convert to a date.
I have tried the following but get the error message
Conversion failed when converting date and/or time from character string
select cast([month-year] as date) from [Reporting].[AIM].[Hires_PBI]
select convert(date, [month-year], 103)from [Reporting].[AIM].[Hires_PBI]
Any ideas here?
Find the values that are causing the problem using try_convert():
select [month-year]
from [Reporting].[AIM].[Hires_PBI]
where try_convert(date, [month-year], 103) is null and
[month-year] is not null;
Once you see what values are causing the problem, you can adjust the conversion logic to convert all values. Or just use try_convert() to get NULL for the non-convertible values.
I have imported csv file to sql server manager. one of column is date but his data type is vachar(50).
I used the basic (cast, convert, try_parse) but still get message:
(Conversion failed when converting date and/or time from character
string.)
could you please help me :)
select cast(
replace(
case
when [factuur_datum] in ('null','')
then null
else [factuur_datum]
end, '-','') as date) as [factuur_datum]
from [dbo].[verkoop]
Please use below query to convert it into date
convert(date,'20-12-2018',105)
This should do what you intend:
select try_cast(replace(factuur_datum, '-', '') as date) as factuur_datum
from [dbo].[verkoop]
Non-dates will result in NULL.
I take it factuur_datum is the date column:
select
cast(factuur_datum as date) as [Alias]
from [dbo].[verkoop]
Not sure what the data looks like so can you include an example?
EDIT
convert(datetime,'factuur_datum',1)
possibly will error out if there are null values so you may need to case out the nulls then convert.
I have the following datetime format ( as varchar ) in my database 13-04-2018 1:05:00.
I need to convert it to the following format: 2018-04-13 01:05:00. As datetime.
Normal convert functions can't do this because they try to take the 13th month, and that month doesn't exist. This error:
The conversion of a varchar data type to a datetime data type resulted
in an out-of-range value.
Does someone know how to convert this date issue?
Using datetimes is always a pain regardless of the language because of all the different formats across the world.
To sort your issue out currently, you need to use a format style which is a third parameter to CONVERT. Personally what I would suggest here is to store as a datetime, because storing datetimes as strings is never a good idea. It just gets too messy later on, but if saved in the format you would like, it would be saved as yyyy-MM-dd hh:mm:ss
SELECT CONVERT(DATETIME, '13-04-2018 1:05:00',103)
You can create your own function to format it in your desired output string.
CREATE FUNCTION FormatMyDate
(#Date DATETIME) RETURNS VARCHAR(20)
AS
BEGIN
RETURN FORMAT(#Date,'yyyy-dd-MM hh:mm:ss')
END
And then you can call it in SELECT statements like this:
SELECT dbo.FormatMyDate(yourDateCol)
FROM yourTable
this takes the date from the format where month comes before day and reverses the 2 values (month and day)
SELECT CONVERT(DATETIME, '2018-13-04 01:05:00', 103);
Results:
2018-04-13 01:05:00.000
This should work for you requirement...
SELECT FORMAT(yourdate, 'yyyy-dd-MM')
Your Solution Bro...
DECLARE #d DATETIME = GETDATE()
SELECT FORMAT ( #d, 'MM-dd-yyyy hh:mm:ss', 'de-de' ) AS 'Hoping your result'
I have VARCHAR column (MyValue) in my table. It has date value in two different format.
MyValue
----------
25-10-2016
2016-10-13
I would like to show them in DATE format.
I wrote query like below:
SELECT CONVERT(date, MyValue, 105) FROM MyTable
SELECT CAST(MyValue as date) FROM MyTable
Both are giving me this error. Conversion failed when converting date and/or time from character string.
Is there anyway convert to DATE datatype format even the value stored in different formats like above?
Expecting your answers. Thanks in advance.
Does this help?
declare #varchardates table
(
vcdate varchar(20)
)
INSERT INTO #varchardates VALUES
('25-10-2016'),
('2016-10-13')
SELECT CONVERT(date,vcdate, case when SUBSTRING(vcdate, 3, 1) = '-'
THEN 105 ELSE 126 END) as mydate
FROM #varchardates
Depending on how many different formats you have in your data, you may need to extend the case statement!
See here for list of the different format numbers
You can use TRY_CONVERT and COALESCE. TRY_CONVERT returns NULL if the conversion fails, COALESCE returns the first NOT NULL value:
SELECT COALESCE(TRY_CONVERT(DATETIME, x, 105), TRY_CONVERT(DATETIME, x, 120))
FROM (VALUES('25-10-2016'), ('2016-10-13')) a(x)
I assumed the value 2016-10-13 is in format yyyy-MM-dd.
You mention in a comment you may have other formats as well. In that case it gets very tricky. If you get a value 01-12-2017 and you have no idea about the format, there is no way to tell whether this is a date in januari or in december.
I have below sample data:
03202012 as date but the column datatype is Varchar.
I want to convert it to 2012-03-20 00:00:00.000 as Datetime.
I tried using
CAST(CONVERT(CHAR(10), Column, 101) AS DATETIME)
But I get an error:
The conversion of a varchar data type to a datetime data type resulted in an out-of-range value.
Complete code snippet to test:
DECLARE #Column VARCHAR(MAX) = '03202012'
SELECT CAST(CONVERT(CHAR(10), #Column, 101) AS DATETIME)
Use yyyyMMdd format, that always works:
DECLARE #myDateString varchar(10) = '03202012';
SELECT cast( substring(#myDateString, 5, 4)+
substring(#myDateString, 1, 2)+
substring(#myDateString, 3, 2) AS datetime);
I found below script help me solved my concern.
SELECT convert(datetime, STUFF(STUFF('31012016',3,0,'-'),6,0,'-'), 105)
Result: 2016-01-31 00:00:00.000
Thanks all for the effort. :D
In MySQL, you can use the STR_TO_DATE function to convert a string to a date. For your example, it would look like this
STR_TO_DATE("03-02-2012", "%m-%d-%Y");
Note that the format part of the string must match the format part of the date.
Edit: Just found out this is for SQL Server, but I assume this will work there as well.
