I export data in csv format from sql server database. It contain 5 column. one column have date and time value. When i checked the date -time value i found date time value is in wrong format. I add the filter but filter not applied on some data. I try to format the data in same format but formatting did not applied on the data. I tried everything to fix the issue but it is not getting fix.
I have attached the sample data please check it from your end.
7/12/2013 14:50
8/12/2013 20:14
9/12/2013 11:38
10/12/2013 15:31
13/12/2013 12:45:50
13/12/2013 14:35:42
13/12/2013 14:37:40

18/12/2013 14:57:35
Data started from 13/12/2013 12:45:50 are not getting change in date time format.
The trouble is that your dates are in french format dd/mm/yyyy you can force them to datetime with the following line :
[datetime]::ParseExact("7/12/2013 14:50", "d/MM/yyyy HH:mm", $null)
[datetime]::ParseExact("13/12/2013 12:45:50", "d/MM/yyyy HH:mm:ss", $null)
Be carefull in you case sometime you've got seconds and a double space between day and time.

My Google Sheets is currently set to UK London GMT
I have some data that is needed in UK format and other data that is needed in US format within the same sheet.
I'm using date time as dd-mm-yyyy hh:mm:ss and have been trying to convert this to US yyyy-mm-dd hh:mm:ss
When formatting the UK date time to as text and using this formula
=ARRAYFORMULA(REGEXREPLACE(A2:A, "(\d{4})-(\d+)-(\d+)", "$3/$2/$1"))
It should be converting for me however is stays the same.
I have also tried simply copying and pasting in a new column with the intention of changing format from within formatting settings but when pasting it seems to randomly select different formats in some rows using / instead of - and in other rows returning a number instead of date time.
How can I get this to work correctly?
try:
=TEXT(A2, "e-m-d h:mm:ss")
I have a column which contians date as string but in many formats like - dd/MM/yy, dd/MMM/yyy .. etc etc. And I am using the following code to convert all strings to one specific date format (yyyy-MM-dd) in hive :
select
from_unixtime(unix_timestamp('31/02/2021','dd/MM/yyyy'),'yyyy-MM-dd')
but this gives me 2021-03-03 in HIVE.
Is there any other way to identify such invalid dates and give null.
Assume, you recognized format correctly and it is exactly 'dd/MM/yyyy' and date is invalid one '31/02/2021'.
unix_timestamp function in such case will move date to the next month and there is no way to change it's behavior. But you can check if the date double-converted from original string to timestamp and back to original format is the same. In case it is not the same, then the date is invalid one.
case
-- check double-converted date is the same as original string
when from_unixtime(unix_timestamp(date_col,'dd/MM/yyyy'),'dd/MM/yyyy') = date_col
--convert to yyyy-MM-dd if the date is valid
then from_unixtime(unix_timestamp('31/02/2021','dd/MM/yyyy'),'yyyy-MM-dd')
else null -- null if invalid date
end as date_converted
I uploaded and parsed through an excel sheet using cfspreadsheet and inserted all the values into database and the problem is that [my excel sheet has a date range from 1/2/2016 to 29/02/2016,from 1/2/16 to 12/2/2016 it is right aligned in excelsheet and remaining is left aligned...]. The value is being inserted into the db but I cannot able to fetch the values from 1-12 using where condition in db. I tried manually changing the date format in my excel sheet..what happened is
..02 January 2016
02 February 2016
.
.
02 December 2016
13/02/2016
14/02/2016
.
.
up to 02/12/2016[mm/dd/yy] it is displaying dd as month notation and from 13/02/2016[dd/mm/yyy] it is displaying properly, I tried with all formatting options, and I need to implement it in code. I think while downloading the data itself the date is not getting formatted properly, I tried with different excel sheet but of no use...and I tried converting these dates into specific format using coldfusion code and but it doesn't works for me..
<cfset sheet = spreadSheetRead("D:\file123\final1231.xls")>
<cfset SpreadSheetFormatColumn(sheet,{dataFormat="yyyy-mm-dd"},3)>
<cfset SpreadSheetWrite(sheet,"D:\file123\final1232",true)>
can any one help me in this?
What looks to me is that locale is set to 'English (United States)' in your excel and that is why for first 12 rows your excel is treating values as valid date but starting 13th row the data is invalid and hence excel is treating it as string (hence left aligned). Try manually changing excel locale to 'English (India)' or similar and you will see data aligned properly.
Also Cold Fusion internal date-time format is American (mm/dd/yyyy) and by default will interpret date and time into American format. I think while inserting data you can create date with something like below to make sure what data gets inserted:
#createDate(listLast(dt,"/"),listFirst(listRest(dt,"/"),"/"),listFirst(dt,"/"))#
Here dt is the data column that you want to insert. You may need to put some checks, based on the data, to avoid any run time errors.
So I have one big file (13 million rows) and date formatted as:
2009-04-08T01:57:47Z. Now I would like to split it into 2 columns now,
one with just date as dd-MM-yyyy and other with time only hh:MM.
How do I do it?
You can simply use tMap and parseDate/formatDate to do what you want. It is neither necessary nor recommended to implement your own date parsing logic with regexes.
First of all, parse the timestamp using the format yyyy-MM-dd'T'HH:mm:ss'Z'. Then you can use the parsed Date to output the formatted date and time information you want:
dd-MM-yyyy for the date
HH:mm for the time (Note: you mixed up the case in your question, MM stands for the month)
If you put that logic into a tMap:
you will get the following:
Input:
timestamp 2009-04-08T01:57:47Z
Output:
date 08-04-2009
time 01:57
NOTE
Note that when you parse the timestamp with the mentioned format string (yyyy-MM-dd'T'HH:mm:ss'Z'), the time zone information is not parsed (having 'Z' as a literal). Since many applications do not properly set the time zone information anyway but always use 'Z' instead, so this can be safely ignored in most cases.
If you need proper time zone handling and by any chance are able to use Java 7, you may use yyyy-MM-dd'T'HH:mm:ssXXX instead to parse your timestamp.
I'm guessing Talend is falling over on the T and Z part of your date time stamp but this is easily resolved.
As your date time stamp is in a regular pattern we can easily extract the date and time from it with a tExtractRegexFields component.
You'll want to use "^([0-9]{4}-[0-9]{2}-[0-9]{2})T([0-9]{2}:[0-9]{2}):[0-9]{2}Z" as your regex which will capture the date in yyyy-MM-dd format and the time as mm:HH (you'll want to replace the date time field with a date field and a time field in the schema).
Then to format your date to your required format you'll want to use a tMap and use TalendDate.formatDate("dd-MM-yyyy",TalendDate.parseDate("yyyy-MM-dd",row7.date)) to return a string in the dd-MM-yyyy format.
When I am using date in a .csv file it creats a problem as like I have used 01/01/2011 it takes 1st jan 2011,that's right but when I use 01/10/2011 it takes it as 10th jan 2011. I mean to say it always takes in mm-dd-yyyy format. I have some gb of files are there to be converted into csv. When I am converting these files dates in the files are in dd-mm-yyyy format. And after conversion the value changes completely.Hence How to resolve this issue? Hope I made my requirement clear.
Try the following:
DateTime.ParseExact("01/10/2011","dd/mm/yyyy",CultureInfo.CurrentCulture);
This specifies the format of the date in the string and should convert your dates correctly.
