How to convert string dd.mm.yyyy to date in SQL - sql

I have column field of varchar type in format dd.mm.yyyy. I am trying to convert this varchar field to date time in SQL server using
CONVERT(Datetime, LTRIM(RTRIM([Completion Date])), 102)
but it gives me error 'Conversion of varchar type to date type results in out of range value'
How to convert this field to datetime format?

use style 104 (dd.mm.yyyy) instead of 102 (yyyy.mm.dd)
CONVERT(Datetime, LTRIM(RTRIM([Completion Date])), 104)
Also the field of type varchar so there could be some bad dates which needs to be eliminated before the conversion .
If you are using SQL SERVER 2012+ then use TRY_CONVERT, for bad dates it will result NULL
TRY_CONVERT(Datetime, LTRIM(RTRIM([Completion Date])), 104)

You can always use this:
SELECT convert(datetime, '23/07/2009', 102)

You can also use this:
SELECT convert(date, '21.12.2016', 104)

You can use convert with date and datetime as below:
SELECT convert(datetime, '27-09-2013', 104)
SELECT convert(date, '27-09-2013', 104)

Out-of-range value when converting dates separated by dots

How can I convert the following VARCHAR(50) data:
01.01.2020 06:10:15
to a DateTime?
Assuming that the dates are in dd.mm.yyyy format, you can use the date and time style #104 (German) that uses this exact format:
SELECT CONVERT(DATETIME, '13.01.2020 06:10:15')
-- The conversion of a varchar data type to a datetime data type resulted in an out-of-range value.
SELECT CONVERT(DATETIME, '13.01.2020 06:10:15', 104)
-- 2020-01-13 06:10:15.000
You can try the below method:
SELECT CONVERT(datetime, '2017-08-25')
in place of the date under singled quotes you can place the variable name.
Try Below Code :
select convert(datetime, '01.01.2020 06:10:15', 104)

You can achieve by this way
Declare #Str VARCHAR(50) = '01.01.2020 06:10:15'
Select CONVERT(date, REPLACE(#Str, '.', '/'), 103)

Convert datetime to specific format in SQL Server

How to convert datetime to this format : 2019/06/17 18:00:00.123
I use select convert(varchar, getdate(), 111) and select convert(varchar, getdate(), 108) together but I get only 2019/06/17 18:00:00
I can't find a combination to get format I need. Is there any way to get it?
You could use FORMAT to return the DATETIME in a specified format (assuming you use SQL-Server and want to return a string type).
DECLARE #example DATETIME = GETDATE();
SELECT FORMAT(#example, 'yyyy/MM/dd HH:mm:ss.fff');
use datetime2 data type and cast getdate to datetime2(3) for 3 digit precesion
select cast( getdate() as DATETIME2(3))

Conversion failed when converting date and/or time from character string when select date

I want date to be displayed as yyyy-mm-dd. The value in the table for date is dd/mm/yyyy. I have run the query
select CONVERT(DATE, FORMDATE, 103) from UPDATELOG
and i got error "Conversion failed when converting date and/or time from character string". Anyone can help me with this?
This certainly looks like SQL Server. So, use try_convert() instead:
select TRY_CONVERT(DATE, FORMDATE, 103)
from UPDATELOG ;
To get the values that fail, use:
select FORMDATE
from UPDATELOG
where TRY_CONVERT(DATE, FORMDATE, 103) is null

How to convert string date into valid date format in SQL Server 2008?

I have string date in yymmdd format, for example 150202
I want to convert this string into a valid date in format yyyymmdd, e.g. 20150202.
Thanks in advance.
convert your string to datetime and then do that you want with it
declare #dt varchar(6) = '150213'
select CONVERT(datetime, #dt, 112)
Do another CONVERT to transform it to yyyymmdd format.
SELECT CONVERT(VARCHAR(10), CONVERT(DATETIME, #dt, 112), 112)
may this will work
select CONVERT(datetime, '150202', 112)
for all date conversions
http://www.sqlusa.com/bestpractices/datetimeconversion/
instead of select CONVERT(datetime, '150202', 112)
its better to use "select TRY_CONVERT(datetime, '150202', 112)"
while using try_convert if there is any error it will returns null,if we are using convert it will returns error when conversion fails.

Sql Server datetime conversion

I am trying to convert varchar date value to datetime format. Showing error
select CONVERT(DATETIME, Convert(varchar, 20/12/2009, 103 ),103)
error: Conversion failed when converting datetime from character string.
Geetha
This should work:
select CONVERT(DATETIME, '20/12/2009', 103)
Not sure what your conversion TO varchar is for...
You need quotes around the string otherwise it treats it as an expression and tries to do the divisions:
select CONVERT(DATETIME, Convert(varchar, '20/12/2009', 103 ),103)
Although having said that only one Convert is really necessary so you can use
select CONVERT(DATETIME, '20/12/2009',103)
I would say you at least have to add quotes arround the string representing the date :
select CONVERT(DATETIME, Convert(varchar, '20/12/2009', 103 ),103)
(Maybe there's another problem too : I don't have an SQL Server instance available, so I cannot test)
You need to quote the date string:
select CONVERT(DATETIME, Convert(varchar, '20/12/2009', 103 ),103)
And you don't need two converts. This is should be enough:
select Convert(varchar, '20/12/2009', 103 )
