I'm trying to convert getdate to a string in YYYYMMDDHHmmss format without much luck. I need to do this in SSIS as a derived column.
I've tried using Datepart, but it's not working.
Datepart("YYYY",(GETDATE())) & datepart("MM",MONTH(GETDATE())) & DATEPART("DD",(GETDATE())) & DATEPART("HH",(GETDATE()) & DATEPART("MM",(GETDATE())) & DATEPART("SS",(GETDATE()))
Any clues what I'm doing wrong?
Try this:
(DT_STR,4,1252)DATEPART( "yyyy" , getdate() ) +
RIGHT("0" + (DT_STR,4,1252)DATEPART( "mm" , getdate() ), 2) +
RIGHT("0" + (DT_STR,4,1252)DATEPART( "dd" , getdate() ), 2) +
RIGHT("0" + (DT_STR,4,1252)DATEPART( "Hh" , getdate() ), 2) +
RIGHT("0" + (DT_STR,4,1252)DATEPART( "mi" , getdate() ), 2) +
RIGHT("0" + (DT_STR,4,1252)DATEPART( "ss" , getdate() ), 2)
This should do it, it simply casts GETDATE() as a string and replaces unnecessary characters.
LEFT(REPLACE(REPLACE(REPLACE((DT_STR,30,1252)GETDATE(),"-",""),":","")," ",""),14)
DATEPART
Returns an integer representing a datepart of a date.
The operation you would like to do is string concatenation for those values. The operator for string concatenation in the SSIS Expression language is +. However, + is also the addition operator for the integer data type so if you use
Datepart("YYYY",(GETDATE())) + datepart("MM",MONTH(GETDATE()))
You would not get 201410. Instead, you'd have a value of 2024. Now, you can use addition to get you were you want to be, you'll just need multiplication as well. (2014 * 100) + 10 will equal 201410 and returns the value as integer so perhaps that fits with what you want. However, once you build out to YYYYMMDDHHMMSS you're probably outside the bounds of Int32 and I'm too lazy to look it up, possibly Int64.
The better approach will be to cast the results of the DatePart to a string and use concatenation. But, there's still a problem there. 05 as an integer is just 5. That leading zero is an artifact of presentation so if you want it in your value, you'll need to explicitly put it there. The preferred method of doing so is to concatenate a leading 0 and then shave off the last 2 characters. For October-December, you'll have a 3 character string 010/011/012 that then gets turned back into 10/11/12. The remaining months will become 01/02/../09 and taking the right two most characters yields the correct values.
RIGHT(("0" +(DT_WSTR, 2) MONTH(GETDATE())), 2)
The & isn't a concatenation operator in this languages so that is problem #1 with your formula.
Here's what worked for me.
(DT_STR, 4, 1252)DATEPART("YYYY", GETDATE())+(DT_STR,2,1252)DATEPART("MM", GETDATE())+(DT_STR,2,1252)DATEPART("DD", GETDATE())+(DT_STR,2,1252)DATEPART("HH", GETDATE())+(DT_STR,2,1252)DATEPART("MI", GETDATE())+(DT_STR,2,1252)DATEPART("SS", GETDATE())
This should give you what you want:
REPLACE(REPLACE(REPLACE(CONVERT(varchar, GETDATE(), 20), '-', ''), ':', ''), ' ', '')

Hi I have one doubt in ssis
I want change date format M/d/yyy hh:mm:ss to yyyy-MM-dd using ssis expression and DateFormat variable datatype is string and getting format like 5/28/2019 12:00:00 AM. Data comes like below:
5/28/2019 12:00:00 AM
Based on above values i want output in other variable
2019-05-28
I tried like expression
(DT_STR, 4, 1252) DATEPART("yy" , #[User::DateFormat]) + "-" +
RIGHT("0" + (DT_STR, 2, 1252) DATEPART("mm" , #[User::DateFormat]), 2) +
"-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("dd" , #[User::DateFormat]), 2)
but getting error like below :
ADDITIONAL INFORMATION:
The function "YEAR" does not support the data type "DT_WSTR" for
parameter number 1. The type of the parameter could not be implicitly
cast into a compatible type for the function. To perform this
operation, the operand needs to be explicitly cast with a cast
operator.
Evaluating function "YEAR" failed with error code 0xC0047089.

can you please tell me how to write expression to achive this task in ssis
The main error is that #[User::DateFormat] variable is a string variable while DATEPART() function can be only applied to a date time value. (Even if the string variable stores a date time value)
You can benefit from TOKEN() function to achieve that:
TOKEN(TOKEN( #[User::DateFormat],"/",3)," ",1) + "-" +
RIGHT("0" + TOKEN( #[User::DateFormat],"/",2),2) + "-" +
RIGHT("0" + TOKEN( #[User::DateFormat],"/",1) ,2)
I have added type casts for date.
This would help
(DT_WSTR, 4) YEAR( (DT_DATE) #[User::Variable] ) + "-" + RIGHT("0"+(DT_WSTR,2) MONTH( (DT_DATE) #[User::Variable] ),2) + "-" + RIGHT("0"+(DT_WSTR, 2) DAY( (DT_DATE) #[User::Variable] ),2)
Create a new variable in your SSIS package with data type String and use the datetime field(here as #[User::Variable]) coming in your input in that variable as in below expression:
(DT_WSTR, 4) YEAR( #[User::Variable] ) + "-" +
RIGHT("0"+(DT_WSTR,2) MONTH( #[User::Variable] ),2) + "-" +
RIGHT("0"+(DT_WSTR, 2) DAY( #[User::Variable] ),2)
You can convert this string variable into date type later on if required.
I'm trying to convert an input of DT_WSTR to DT_TIMESTAMP on SSIS Derived column and when I do it the values do not match up, on one ocasion it recognizes the year correctly but on the other it think the day is the year
I tried to do
(DT_TIMESTAMP)((DT_WSTR,4)YEAR([Data Hora]) + RIGHT("0" + (DT_WSTR,2)MONTH([Data Hora]),2) + RIGHT("0" + (DT_WSTR,2)DAY([Data Hora]),2) + (DT_WSTR,10) Time_Column)
with no success
08-04-19 15:31:27 this is what I input and sometimes it recognizes the 19 as 2019 correctly but other times it thinks the 08 is the year so it puts 19/04/2008, I want the first one.
I expect to get the date correctly in dd/mm/yyyy hh:MM:ss.
Your question is not clear. In this answer I will try to fix the provided expression. Try using the following expression:
(DT_DBTIMESTAMP)((DT_WSTR,4)YEAR([Data Hora]) + "-" +
RIGHT("0" + (DT_WSTR,2)MONTH([Data Hora]),2) + "-" +
RIGHT("0" + (DT_WSTR,2)DAY([Data Hora]),2) + " " +
(DT_WSTR,10) [Time_Column])
Another suggestion is that, in cases where the date format is tricky (2 digit year part), it is better to use a script component to parse the date value since it provides more options using Date.ParseExact() function, as example:
Row.outDateColumn = DateTime.ParseExact(Row.inStringDate,"dd-MM-yy HH:mm:ss",System.Globalization.CultureInfo.InvariantCulture);
I am trying to concatenate 'week' with an integer value column from flat file resource on SSIS derived column. this is what I did
(("week" + " " + (DT_WSTR, 20) RIGHT( [CalendarWeek] ,2 ))
but I am getting error, please explain with this example or how to use 'right' function with DT_WSTR
Let's look at the expression you are using
(("week" + " " + (DT_WSTR, 20) RIGHT( [CalendarWeek] ,2 ))
Reading left to right: using the literal string week, append a space, concatenate to that the result of casting to a unicode string of length 20, the rightmost two characters of CalendarWeek.
Where could the errors be?
CalendarWeek could be numeric field. RIGHT works against a string data type so this would be incorrect. You'd need to cast your data to a string type before performing string manipulation on it.
Logically, you have an error with your concatenation. You are asking for 2 characters from CalendarWeek and then stuffing it into a 20 character wide string.
"week" + " " + RIGHT(((DT_WSTR, 20) [CalendarWeek]),2)
Assuming I've counted my parenthesis correctly, I believe the expression you are looking for is above.
I'm trying to format a datestamp to have leading zeros in an expression using SSIS 2008 R2.
My desired result would be Exceptions - YYYYMMDDHHMMSS.xls so as an example, now would be:
\\SomePath\Exceptions - 20150211155745.xls
I am having an issue adding the leading zeros to the day and month though.
I've tried the following expressions by trying to convert to DT_WSTR with the length set as well as picking the date apart usg SUBSTRING:
#[User::XLFileRootDir] + "Exceptions - " + (DT_WSTR, 4) DATEPART("YYYY", GETDATE()) + (DT_WSTR, 2) DATEPART("MM", GETDATE()) + (DT_WSTR, 2) DATEPART("DD", GETDATE()) + ".xls"
This results in \\SomePath\Exceptions - 2015211155745.xls (notice the missing leading zero on the month).
#[User::XLFileRootDir] + "Exceptions - " + (DT_WSTR, 4) SUBSTRING(GETDATE(), 1, 4) + ".xls"
This results in an error as the data type DT_DBTIMESTAMP isn't supported by the function SUBSTRING. I'm aware that some sort of conversion needs to take place but can't find a function within SSIS to complete this.
Could anyone help me with how to format the expression with leading zeros?
The problem you're running into is that the YEAR/MONTH/DAY functions return an integer. An integer won't present leading zeros. Therefore, the "trick" is to convert it to a string. Prepend a leading zero to that string. Then, shear off the last 2 characters using the RIGHT function. The trimming is only required for October, November, and December but the logic is cleaner to unconditionally apply RIGHT.
This builds your YYYYMMDD string.
(DT_WSTR, 4)YEAR(#[System::StartTime])
+ RIGHT("0" + (DT_WSTR, 2) MONTH(#[System::StartTime]), 2)
+ RIGHT("0" + (DT_WSTR, 2) DAY(#[System::StartTime]), 2)
I find it better to use the variable System::StartTime rather than GETDATE(), especially when time is involved. GETDATE will be evaluated each time it is inspected. Over long running packages, there can be a sizable drift in the values returned. System::StartTime is the time the package itself began. It is constant for the run itself but obviously resets per run.
For my application, I needed the exact current time, and I needed it down to the second, which yielded this:
(DT_WSTR, 4)DATEPART("yyyy",GETDATE())
+ RIGHT("0" + (DT_WSTR, 2) DATEPART("mm",GETDATE()),2)
+ RIGHT("0" + (DT_WSTR, 2) DATEPART("dd",GETDATE()),2)
+ RIGHT("0" + (DT_WSTR, 2) DATEPART("Hh",GETDATE()),2)
+ RIGHT("0" + (DT_WSTR, 2) DATEPART("mi",GETDATE()),2)
+ RIGHT("0" + (DT_WSTR, 2) DATEPART("s",GETDATE()),2)
SUBSTRING((DT_WSTR, 29) GETDATE(), 6, 2)
I have this string which is a combination of date and time but in string format meaning that it has no space. I parsed it from a very long string but I now have or need to convert it to a standard date and time.
This is my string for date and time:
141007024755
This is how I parsed it from a very long string of data
[date&time] = SUBSTRING(#ProductCode, 27, 12)
This is the format I'm expecting but can't do it.
2014-10-07 02:47:55.000
Can anyone give me a hint on how to do this? An advice perhaps.
Thanks.
If the string is always 12 characters long you could try this:
select cast(stuff(stuff(stuff('141007024755', 7,0,' '), 10,0,':'), 13,0,':') as datetime)
Basically it uses the stuff function to insert a space between the date and time parts and colons between the different time parts producing a string like141007 02:47:55that can be converted todatetimeusingcast.
Assuming the dates are formatted exactly as your sample string, you can just keep chopping up the string and appending it back together and cast the result to date. Simple function like this may help:
CREATE FUNCTION dbo.udf_ReturnDateFromString(#DateString AS VARCHAR(14))
RETURNS DATETIME
AS
BEGIN
SET #DateString = '20' + #DateString
RETURN CAST(LEFT(#DateString, 4) + '-' +
SUBSTRING(#DateString, 5, 2) + '-' +
SUBSTRING(#DateString, 7, 2) + ' ' +
SUBSTRING(#DateString, 9, 2) + ':' +
SUBSTRING(#DateString, 11, 2) + ':' +
SUBSTRING(#DateString, 13, 2) AS DATETIME)
END;
GO
SELECT dbo.udf_ReturnDateFromString('141007024755');
The result is:
2014-10-07 02:47:55.000
You get the idea. This was done on SS 2008 R2.
