I want to display the time stamp in following format '2011-04-22 10:41:57.000' to date as '04/22/2011' but when it convert it to following form TO_DATE(TO_CHAR(Date), 'MM/DD/YYYY HH24:MI:SS') it is displaying as null.
I am planning to use substring after the conversion
Can someone please tell me where i am going wrong?
You can simply do TO_CHAR(Date, 'MM/DD/YYYY')
i used 'TO_DATE(TO_CHAR(Date), 'MM/DD/YYYY HH24:MI:SS')' and later 'SUBSTR(Date_V,1,11)' and i got required output

I had a problem with my code. It returns the below error:
DAX comparison operates do not support comparing values of type date with values of type text.
Basically, I want to count rows based on some conditions. And I know there is a need to convert the data type, but I am not sure how to do it.
Total Open Issues =
--------------------
--basic info
VAR SELECTEDDATE =
DATEVALUE(SELECTEDVALUE(Calender[FullDateAlternateKey].[Date]))
--------------------
--FIND the relvent data
VAR rlvttable =
calculatetable(
Tracker,
Tracker[Catagory]="ISSUE",
DATEVALUE(Tracker[ClosedDate])>SELECTEDDATE
||Tracker[ClosedDate]=""
)
--------------------
--Results
Return
countrows(rlvttable)
Anyone could advise me how to correct it? Thanks~
Check the data type of columns Tracker[ClosedDate] and Calender[FullDateAlternateKey] - one of them is Text, rather than Date.
To fix, you could:
choose a different field which is already a Date format
change the format of the offending column
use DATEVALUE in your measure, to convert the text date to a real date.
It also looks like you need to edit this statement, as these conditions conflict:
Tracker[ClosedDate]>SELECTEDDATE
&&Tracker[ClosedDate]=""
I am trying to compare the closedDate with "". I should use blank() instead.
I am trying to validate date which is coming from an excel sheet , the format should be in dd/mm/yyyy
i tried with regex pattern [0-9]{2}/[0-9]{2}/[0-9]{4}
but this won't work with single digit date and we since we cannot add 0 at start in excel sheet this pattern ain't working. (this is for blueprism tool which have a action for regex matching]
To build in the resiliency you require, you'll have to accept either 1 or 2 digits for both dd and mm:
[0-9]{1,2}/[0-9]{1,2}/[0-9]{4}
Since you are mentioning that you are working with BluePrism, are you sure that you really need Regex for validating dates? Because BP has built-in feature for that callable directly inside a Calc stage - checkout following example (you can see Expression of selected Calc stage in top Expression bar).
The function used for validating dates is IsDate([Some date as string]), result is saved into a Flag data-item.
After the check you can use that Flag data-item in a Decision block and do whatever you consider appropriate if a date is not an actual date.
Note: of course, if you are working with lists/datatables in a Code stage instead of iterating over a collection in process layout, then you need something else, but this might be still helpful.
In Code stage I would probably simply use DateTime.Parse(String) method which is able to automatically convert a date in a form of a String into a DateTime object instance; example:
' DateTime.Parse throws an Exception if parsing failed.
Dim valid As Boolean = False
Try
Dim d = DateTime.Parse(First_Date)
valid = True
Catch e As Exception
valid = False
End Try
See more about parsing dates using DateTime.Parse at MSDN: https://msdn.microsoft.com/en-us/library/1k1skd40(v=vs.110).aspx
There is also a nice post about parsing dates here: https://stackoverflow.com/a/18465222/7439802
In blue prism you can use
FormatDate(Now(), FormatOfDate)
For comparing two dates, initially Convert(" FormatDate ") in same format and then you can compare.
For " FormatDate " option you can refer Help of Blue prism and search for dateadd --> select the Calculation and decision
I want to convert the string 20160101000000 into datetime format using expression. I have used below date function
TO_DATE(PERIOD_END_DATE),'MM/DD/YYYY HH24:MI:SS')
But my table file is not loading. My session and workflow gets succeed. My target and source is also flatfile.
I want to change the string 20160101000000 into MM/DD/YYYY HH24:MI:SS for loading data into my target table.
You need to give exact format that looks so that to_date function can understand that format and converts it into date.
TO_DATE(PERIOD_END_DATE,'YYYYMMDDHH24MISS')
So here your date looks like YYYYMMDDHH24MISS (20160101000000).
There is often confusion with the TO_DATE function... it is in fact for converting a string into a date and the function itself is to describe the pattern of the incoming date. Now if you want to convert a date field to a specified date format you must use TO_CHAR
We have a staging table that's used to load raw data from our suppliers.
One column is used to capture a time-stamp but its data-type is varchar(265). Data's dirty: about 40% of the time, there is garbage data, otherwise time-stamp data like this
2011/11/15 20:58:48.041
I have to create a report that filters some dates/timestamps out that column but where I try to cast it, I get an error:
db2 => select cast(loadedon as timestamp) from automation
1
--------------------------
SQL0180N The syntax of the string representation of a datetime value is incorrect. SQLSTATE=22007
What do I need to do in order to parse/cast the timestamp string?
The string format for a DB2 timestamp is either:
'2002-10-20-12.00.00.000000'
or
'2002-10-20 12:00:00'
You have to get your date string in either of these formats.
Also DB2 runs on a 24 hour clock even though the output sometimes uses a 12 hour clock (AM / PM)
So '2002-10-20 14:49:50' For 2:49:50 PM
Or '2002-10-20 00:00:00' For midnight. Output would be 12:00:00 AM
It seems you have a lot of garbage data, so firt of all you should check if the data is a valid timestamp in the format you expect ('2011/11/15 20:58:48.041'). We could use a simple solution - just replace all digits with '0' and check the result format:
TRANSLATE(timestamp_column,'0','0123456789','0') = '0000/00/00 00:00:00.000'
If the format is the expected one, you should convert to DB2 timestamp. In DB2 for iSeries there is a build-in function since V6R1 TIMESTAMP_FORMAT. In your case it will look like that:
TIMESTAMP_FORMAT('2011/11/15 20:58:48.041','YYYY/MM/DD HH24:MI:SS.NNNNNN')
So the solution query combined should look something like that:
SELECT
CASE
WHEN TRANSLATE(timestamp_column,'0','0123456789','0') = '0000/00/00 00:00:00.000'
THEN TIMESTAMP_FORMAT(timestamp_column,'YYYY/MM/DD HH24:MI:SS.NNNNNN')
ELSE NULL
END
FROM
your_table_with_bad_data
EDIT
I just saw your comment that provider agreed to clean the data. You could use the solution provided to speed up the process and clean the data by yourself:
ALTER your_table_with_bad_data ADD COLUMN clean_timestamp TIMESTAMP DEFAULT NULL;
UPDATE your_table_with_bad_data
SET clean_timestamp =
CASE
WHEN TRANSLATE(timestamp_column,'0','0123456789','0') = '0000/00/00 00:00:00.000'
THEN TIMESTAMP_FORMAT(timestamp_column,'YYYY/MM/DD HH24:MI:SS.NNNNNN')
ELSE NULL
END;
Below is the two lines of code that throws error:
<#assign test2="20:56:20"?time("HH:mm:ss")>
${test2?date}
The second line ends up with error:
freemarker.template.TemplateException: Cannot convert TIME into DATE
I know this is expected. But how can I check, if a date variable has got the 'date' value before displaying it on screen? For ex: In above example, i would like to check if 'test2' contains a date part before diplaying it on screen.
This is how i usually do it:
dateIssued?datetime("MM/dd/yyyy hh:mm a")
or
dateIssued?datetime("hh:mm a")
or
dateIssued?datetime("MM/dd/yyyy")
Just make sure you passing into your model java.util.Date
So I just use the datetime all the time. Hope this will help you.
