I have varchar column as dataset as:
20110712
20141229
20100222
20140408
20131117
20130912
20140702
20110405
That need to be converted datetime datatypes. I have tried: CONVERT(date, column_name) yet it returns the error:
Msg 241, Level 16, State 1, Line 1
Conversion failed when converting date and/or time from character string.
How can I ensure that this will work?
If your date is a varchar, then you should be able to use CONVERT(DATE,[date_field], 112)
DECLARE #dates TABLE
(
[date] varchar(10)
)
INSERT INTO #dates([date])
VALUES('20110712'),('20141229'),('20100222'),('20140408'),('20131117'),('20130912'),('20140702'),('20110405')
SELECT CONVERT(date,[date],112)
FROM #dates

I have a table that has a column for dateofbirth varchar(10). All the data inside is stored like this '02/01/1990'.
I need to convert it to datetime. I've tried
CAST(DateofBirth AS DATEITME) AS BirthDate
But I keep getting this error when I try importing:
The conversion of a varchar data type to a datetime data type resulted in an out-of-range value"
I need it like this:
1990-02-01 00:00:00:000
SELECT CONVERT(Datetime, '2011-09-28 18:01:00', 120) -- to convert it to Datetime SELECT CONVERT( VARCHAR(30), #date ,105) -- italian format [28-09-2011 18:01:00] + ' ' + SELECT CONVERT( VARCHAR(30), #date ,108 ) -- full date [with time/minutes/sec]
You need to convert a Varchar in format MM/DD/YYYY to a Datetime.
Sql server recognizes a set of predefined date formats that it is able to automatically parse. See this cheat list.
Your input format corresponds to sql server date format 101, hence you can do :
SELECT CONVERT(Datetime, '02/01/1990', 101)
If you try to do it in sql query there is syntax to do it .
Here a link ..
SQL Server Convert Varchar to Datetime
Your cast statement works for me:
Declare #dateofbirth varchar(10) = '02/01/1990'
select cast(#dateofbirth as datetime)AS BirthDate
Result:
BirthDate
1990-02-01 00:00:00.000
Select c1.CDS_Date, c2.CDS_Date, Dateadd(day, -1 , c2.CDS_Date)
from cte as c1 left join
cte as c2
on c1.[Local Patient Identifier] = c2.[Local Patient Identifier] and
c1.JoinKey = c2.JoinKey - 1
Can I get come help please?
I got no issues with c1.CDS_Date and c2.CDS_Date.
I receive the following error message as soon as I include the 3rd column:
(24 rows affected)
Msg 242, Level 16, State 3, Line 50
The conversion of a varchar data type to a datetime data type resulted in an --out-of-range value.
That is because your CDS_Date is not of date/datetime type but is a string.
Here is an example:
declare #t table (CDS_Date varchar(100));
insert into #t values ('28/10/2017');
set language British;
select CDS_Date, dateadd(day, -1, CDS_Date) as dt
from #t;
-------
--CDS_Date dt
--28/10/2017 2017-10-27 00:00:00.000
set language us_english;
select CDS_Date, dateadd(day, -1, CDS_Date) as dt
from #t;
--Msg 242, Level 16, State 3, Line 40
--The conversion of a varchar data type to a datetime data type resulted in an out-of-range value.
This example shows you that not every string can be converted to date EVEN IF it seems to you that it represents a valid data. This is because server expects a date that you pass as a string to be in the certain format that depends on session language.
To be independent of session language you shoud pass your date string using convert function and specifying the format of your date.
In my example I can fix the issue converting to date with style 103:
select CDS_Date, dateadd(day, -1, convert(date, CDS_Date, 103)) as dt
from #t;
----
--CDS_Date dt
--28/10/2017 2017-10-27
Now it gives me the correct result in both languages just because it knows that my input strings are of 103 format, i.e. dd/mm/yyyy
I want to convert the julian date in a date format.
Below, please find an example to create my error. All my dates have 5 digits I need to convert.
create table #test (dateR int)
insert into #test (dateR)
values (39596),(39596),(39595),(39595),(39593),(39592),(39592),(39589),(38104),(38104),(37957)
SELECT * from #test
select *
, dateadd (year, dateR/1000 - 1900, dateR %1000 - 1) as Rd
from #test
Getting the error:
Msg 517, Level 16, State 1, Line 2 Adding a value to a 'datetime'
column caused an overflow.
Also tried:
SELECT DATEADD(dd, CONVERT(int, RIGHT(dateR,3)) - 1, CONVERT(datetime,SUBSTRING(dateR,1,2)+'0101', 212))
This returns:
Msg 8116 level 16 state 1 line 1 nullArgument data type int is invalid for argument of substring function
You can just cast the INT value to a DATETIME.
For example:
SELECT CAST(39596 AS DATETIME); -- Returns 2008-05-30 00:00:00.000
The following SQL
select creationdate as dt
from dbo.Posts2
where dt > '2013-06-31'
gives error when running:
Msg 207, Level 16, State 1, Line 1
Invalid column name 'dt'.
Update
this works:
Declare #date as varchar(30)
set #date='2008-07-31 21:42:52.667'
select convert(datetime,#date, 101) as [DateColumn]
but this failed:
select creationdate from dbo.Posts2
where convert(datetime, creationdate, 101) > '2013-06-31'
The error is:
The conversion of a varchar data type to a datetime data type resulted
in an out-of-range value.
Why??
You can't use aliases in the where clause.
Just write
where convert(datetime, creationdate) > '2013-06-31'
Edit about the datetime/varchar conversion error:
You are trying to compare to a date that doesn't exist: June only has 30 days, so '2013-06-31' is not a date for SQL Server.
How to convert an int column ,Birthdate( sample value 20090301) to a date column in the format(01/03/2009)
Sql Server 2000
I was trying to convert some thing like below
select * from tabl
where
cast(dob as datetime)>='01/03/2009'
which gives an error
Msg 8115, Level 16, State 2, Line 1
Arithmetic overflow error converting expression to data type datetime.
SQL Server doesn't allow you to cast int -> datetime directly, but if you're sure you can cast it to nvarchar first and then cast it to date.
For your question here's an example
declare #test int = 20090301
select CONVERT(datetime, CAST(#test as nvarchar), 112)
112 is the format you mentioned, here's the list of all possible formats for Convert function.
try this !
select * from tabl
where
cast(convert(char(8),dob, 112) as date)>='2009-03-01'
