I am using SQL Server 2008 and I have two columns in date format:
Column_1: [2014-12-19]
Column_2: [2015-08-31]
I want to merge them and change the the data type to NVARCHAR.
I tried this code
CONVERT(NVARCHAR,[ Column_1])+CONVERT(NVARCHAR,[Column_2])AS TEST
but I get this result:
2014-12-192015-08-31
instead of 2014121920150831 without the hyphens.
Could you please help?
Thanks
Although you can fiddle around with conversion codes, just use replace:
REPLACE(CONVERT(NVARCHAR(255), Column_1) + CONVERT(NVARCHAR(255), Column_2), '-', '') AS TEST
Or, if you don't want to be dependent on the local date format:
CONVERT(NVARCHAR(255), Column_1, 112) + CONVERT(NVARCHAR(255), Column_2, 112) AS TEST
CONVERT has a third parameter which determines the format of the date/time. See here for definition. Code 112 will give you what you want.
You can also use REPLACE to remove the hyphens.
Try this
DECLARE #date1 date = '2014-12-19',
#date2 date = '2015-08-31'
SELECT CONVERT(VARCHAR(8), #date1, 112)+CONVERT(VARCHAR(8), #date2, 112)

This is my query:
declare #date char(10)
set #date = '11.08.1982'
select substring(#date,1,2)+ '/'+
SUBSTRING(#date,3,1)+ '/'+ SUBSTRING(#date,4,4) as resultat
I want to use CONVERT function to convert the result to datetime. How can I do this?
You can't convert this to date and time, however you can use replace function :
select replace(#data, '.', '/')
SQL Server is pretty good about picking up the format of a date with no conversion format. So, this works on db<>fiddle, assuming you intend MM.DD.YYYY for the format:
select convert(date, '11.08.1982')
If you want DD.MM.YYYY, then you can explicitly use the "104" format:
select convert(date, '11.08.1982', 104)
You don't have a time component, so I converted these to date. The same works for datetime.
I need to change the date format from 'yyyy-mm-dd' to 'dd.mm.yyyy'.
I have data in my table like this '2018-08-08', I need convert it to '08.08.2018'.
I have tried:
UPDATE daily_tasks
SET date = REPLACE(date, date, CONVERT(VARCHAR(255), daily_tasks.date, 102))
WHERE 1;
But, it doesn't work.
Ideally you should be storing your dates as bona-fide date columns, not as text. That being said, the date text '2018-08-08' is in fact in an ISO format, and would still allow you to do things like sort and compare against other date literals, so it is not so bad.
But converting this text to a '08.08.2018' format is the wrong thing to do. If a anything, you might want to consider adding a new date column new_date to store this date information. Do that, and then populate it with:
UPDATE daily_tasks
SET new_date = TRY_CONVERT(datetime, date);
Store your date as DATE datatype and when you read data from database use
DECLARE #myDate DATE = '2018-08-08'
SELECT FORMAT(#myDate, 'dd.MM.yyyy')
SELECT CONVERT(VARCHAR(10), #myDate, 104)
Your syntax looks like SQL Sever, so i would do :
UPDATE daily_tasks
SET Col = REPLACE(CONVERT(VARCHAR(10), daily_tasks.date, 103), '/', '.')
WHERE . . . ;
However, i would not recommend to do this, just use CONVERT() with SELECT statement whenever necessary :
SELECT REPLACE(CONVERT(VARCHAR(10), daily_tasks.date, 103), '/', '.')
Regardless of the database, dates are stored in an internal format. This is the correct way to store dates. Do not store dates as strings.
You can specify the format when you query:
CONVERT(VARCHAR(255), daily_tasks.date, 102)
Or, you can even add a computed column to provide this information:
alter table daily_tasks
add date_display as ( CONVERT(VARCHAR(255), daily_tasks.date, 102) ) ;
You could convert the date column to a varchar to store the date in your specified format. However I strongly recommend against this. You should leave it stored as a date.
If you want to do a SELECT to get the data out then you can convert it to your specified format like this:
SELECT CONVERT(VARCHAR, daily_tasks.date, 4)
I have a table in SQL Server with a column RGSTR_DATE that is of varchar(10) data type, and it has values like 2016-01-23, 1998-08-12, etc...
I want to select and convert those values to 20160123, 19980812, etc...
I tried running these queries:
SELECT CONVERT(DATE, CAST(RGSTR_DATE AS DATE), 112)
FROM [project].[dbo].[my_table];
SELECT CONVERT(VARCHAR(10), RGSTR_DATE, 112)
FROM [project].[dbo].[my_table];
But the results that came back were still 2016-01-23, 1998-08-12 etc...
What am I doing wrong?
Did you try
SELECT CONVERT(VARCHAR(10),cast(RGSTR_DATE as date),112)
You're converting a varchar to a date, but all you need to do is remove the hyphens.
SELECT REPLACE(RGSTR_DATE, '-', '')
FROM [project].[dbo].[my_table]
I have date in column of nchar(255) datatype in this format
mm/dd/yyyy
Now I want to change it into
dd/mm/yyyy
I don't think that CONVERT help me in this as I have tried different queries like below
SELECT CONVERT(NCHAR(20), col1, 103) from table1
SELECT CONVERT(VARCHAR(20), col1, 103) from table1
select Convert(varchar(10),CONVERT(date,col1,101),103) from table1
In my view 103 which is in UK format converts only from yyyy-mm-dd
So I tried to CAST my col1 but I get an error.
Am I missing something? Is there any easy way to do this?
Do this in two expiicit steps. First, convert the string to a date using the 101 format (which is mm/dd/yyyy). Then explicitly convert the date back to a string using 103 (which is dd/mm/yyyy):
select convert(varchar(255), convert(date, datecol, 101), 103)
Two points. First, I don't think the result needs to be nvarchar() (the string only consists of numbers and a slash). Second, always include a length when using varchar() in SQL Server.
Here is a little SQL Fiddle.
You can try this:
SELECT CONVERT(VARCHAR, CONVERT(DATETIME, col1, 101), 103)
Check this:
Select convert(varchar(15), cast('01/26/2015' as datetime), 103) as FormattedDate
Where, '01/26/2015' is your col1
Edited Answer:
Select convert(nchar(255), cast(col1 as datetime), 103) as FormattedDate From table1
Where table1 is your table.
I am answering my own question.(Just in case anyone wants to know what is the solution)
There was no such problem with the query i was using. i.e.
select Convert(varchar(10),CONVERT(date,col1,101),103) from table1
The problem was with my nchar field.
It was having a special character (in my case a space) in every entry which was giving "out-of-range" error when tried to convert or cast.
So removing Special character(a space) solved my problem.
In SQL Server how do I format getdate() output into YYYYMMDDHHmmSS where HH is 24 hour format?
I've got the YYYYMMDD done with
select CONVERT(varchar,GETDATE(),112)
but that is as far as I got.
Thanks.
Just for anyone searching for this functionality that has SQL Server 2012 you can use the FORMAT function:
SELECT FORMAT ( GETDATE(), 'yyyyMMddHHmmss') AS 'Custom DateTime'
This allows any .NET format strings making it a useful new addition.
select replace(
replace(
replace(convert(varchar(19), getdate(), 126),
'-',''),
'T',''),
':','')
Close but not exactly what you are asking for:
select CONVERT(varchar, GETDATE(), 126)
e.g.
2011-09-23T12:18:24.837
(yyyy-mm-ddThh:mi:ss.mmm (no spaces), ISO8601 without timezone)
Ref: CAST and CONVERT
There is no way to specify a custom format with CONVERT(). The other option is to perform string manipulation to create in the format you desire.
Try this:
select CONVERT(varchar, GETDATE(), 120)
e.g.
2011-09-23 12:18:24
(yyyy-mm-dd hh:mi:ss (24h) ,ODBC canonical).
Hth.
Another option!
SELECT CONVERT(nvarchar(8), GETDATE(),112) +
CONVERT(nvarchar(2),DATEPART(HH,GETDATE())) +
CONVERT(nvarchar(2),DATEPART(MI,GETDATE())) +
CONVERT(nvarchar(2),DATEPART(SS,GETDATE()));
converting datetime that way requires more than one call to convert. Best use for this is in a function that returns a varchar.
select CONVERT(varchar,GETDATE(),112) --YYYYMMDD
select CONVERT(varchar,GETDATE(),108) --HH:MM:SS
Put them together like so inside the function
DECLARE #result as varchar(20)
set #result = CONVERT(varchar,GETDATE(),112) + ' ' + CONVERT(varchar,GETDATE(),108)
print #result
20131220 13:15:50
As Thinhbk posted you can use select CONVERT(varchar,getdate(),20) or select CONVERT(varchar,getdate(),120) to get quite close to what you want.
select CONVERT(nvarchar(8),getdate(),112) +
case when Len(CONVERT(nvarchar(2),DATEPART(HH,getdate()))) =1 then '0' + CONVERT(nvarchar(2),DATEPART(HH,getdate())) else CONVERT(nvarchar(2),DATEPART(HH,getdate())) end +
case when Len( CONVERT(nvarchar(2),DATEPART(MI,getdate())) ) =1 then '0' + CONVERT(nvarchar(2),DATEPART(MI,getdate())) else CONVERT(nvarchar(2),DATEPART(MI,getdate())) end
