I need to check if the date is Null then use today's date and if not do something else.
If RowModifiedOn IS NULL Then
GETUTCDATE()
ELSE
DATEADD("Hh",@[User::TimeZone],RowModifiedOn)
End If
What do I do wrong here? Can I do something like it?
RowModifiedOn == NULL ? GETUTCDATE() : DATEADD("Hh",@[User::TimeZone],RowModifiedOn)
Thanks.
I am trying to put the following as an expression in the SSIS Derived Column Transformation Editor.
DATEADD(DAY, DATEDIFF(DAY, 0, GETDATE()), 0)
It is not allowing it. This works fine in a regular SQL statement.
Does anyone know how I can get this to work?
Greetings, I am attempting to create a flat file delimited by |. I am using (ISNULL(LIN1_OPT_ADDR) ? "" : LIN1_OPT_ADDR + "| ") to replace the blank address column with the pipe delimiter. So that a row that would consist of:
Customer Number,Name,Address Line1,City,State
12345,ACE HARDWARE INC. ,801 Rockefeller St.,New York, New York
56789,BUILDING SUPPLY INC., ,Wichita, Kansas
Should end up as:
12345|ACE HARDWARE INC.|801 Rockefeller St.|NEW YORK|NEW YORK
56789|BUILDING SUPPLY INC.||Wichita|Kansas
When I run the data flow to create the flat file the file contains the following:
12345|ACE HARDWARE INC.|801 Rockefeller St.|NEW YORK|NEW YORK
56789|BUILDING SUPPLY INC.| | |Wichita|Kansas
Can anyone tell me what I am doing wrong?
Thanks.
The "window" if you call it that to enter in complex derived column logic is painful (at best). At a minimum, the entry line should (just like in the cases where SQL is entered into a ole db command, sql exec etc) open a editor window to allow you to work in something other than a single long line.
In addition, allowing for cr/lf in the text would then allow the text to be formated/indented in meaninful ways. The issue now, once you nest a few statements together, it get VERY confusing and not easy to read since the whole thing is required to be on a single line.
(This same issue exists with line in which you need to enter the text in a conditional split).
THANKS!

I'm having trouble coming up with a valid expression in my derived column transformation editor that tests the input column for NULL and responds something like this:
if[message] isNull then "NA" else [message]
where [message] is the input column.

Hi
I'm a relative SQL Server newbee and have developed a function that converts mm/dd/yyyy to yyy/mm/dd for use as in a DT_DBDATE format for insert into a column with smalldatatime.

Two questions regarding Derived Columns in SSIS
1. In a if else expression if condition is false how do you keep the value of the source column eg: Name == "" ? "Unknown" : Name
Above will change all the non blank values to Name and not the actual value
in the Name Column eg. John
2. I have a column (unicode string)that stores date and time (The source is flat file) Is it possible to write expression to select the 1st day of month based on that date, and use this derived column as input to a table with a datetime field.
Hi,
I apologize if this question has already asked (I already looked in this forum but do not find the answer), I need to have this done as soon as possible. I've following data:
column1 column2 begin_date active
------------- ------------ ---------------- -----------
1253 1057 1/1/2006 0
1253 1057 1/1/2007 0
1253 1057 4/1/2007 0
1253 1057 7/1/2007 1
I need to have the final result as following: (the new end_date column is the value of the begin_date in the next row -1)
column1 column2 begin_date active end_date
------------- ------------ ---------------- -------- ------------------
1253 1057 1/1/2006 0 12/31/2006
1253 1057 1/1/2007 0 3/31/2007
1253 1057 4/1/2007 0 6/30/2007
1253 1057 7/1/2007 1 null
Any ideas?
Thank you!
Hi,
In a nut shell I want to be able to instruction some Data Analysts on how to modify SSIS packages using the simpliest solutions possible. This is because there are many different data sources and some of these data sources have a huge number of fields, and yes you guessed it these data sources are subject to change on a regular basis.
A very common task they will need to do is to modify an SSIS package to do a to transform of a source date string format of "YYYYMMDD" into a date data type field within a table.
Similar threads have advised the use of the Data Flow Transformations->Derived Column for this sort of thing.
So within the Expression Text box I have inserted the following SSIS compatible SQL to convert the above string into a british format date data type; -
Code Snippet
(SUBSTRING(DOB_SRC,8,2) + "/" + SUBSTRING(DOB_SRC,5,2) + "/" + SUBSTRING(DOB_SRC,1,4))
But really what I want to be able to do is to instruct the Data Analysts to do is something like; -
ConvertTextToDate(DOB_SRC)
Where I previously defined that behaviour of ConvertTextToDate as a public VB.NET function.
Can someone please help. I'm pretty certain I'm not the only one with this type of requirement.
Thanks in advance,
Kieran.
Hello All,
Can someone help me out in providing the STEPS to solve this problem. My scneario is, I've a table which has got 2 fields and 5 default row values have been filled in. Now, using the above, duirng package runtime, it need to dynamically create additional field and has to store values like for.e.g (0001 America). I'm getting the following error while executing the ssis package.
1. [DTS.Pipeline] Warning: Component "Derived Column" (1170) has been removed from the Data Flow task because its output is not used and its inputs have no side effects. If the component is required, then the HasSideEffects property on at least one of its inputs should be set to true, or its output should be connected to something.
2. [DTS.Pipeline] Warning: Source "OLE DB Source Output" (87) will not be read because none of its data ever becomes visible outside the Data Flow Task.
Please suggest with your valuable solution at the earliest.
Thanks

How would one add this as a derived column
CASE
WHEN Data IS NULL
THEN NULL
WHEN SUBSTRING(REPLICATE('0', 9 - LEN(Data)) + CAST(CYCLE_YYYYMM AS VARCHAR(9)), 4, 6) IS NULL
THEN 0
ELSE RTRIM(SUBSTRING(REPLICATE('0', 9 - LEN(Data)) + CAST(Data AS VARCHAR(9)), 4, 6))
END
From what I have seen the first option is not really required

Hi,
I am trying to upload a csv file into a destination SQL Server table using Data FLow objects in MS SQL Server 2005 SSIS. My destination table X has a date column while my source data file (for which i have a flat file connection) does not have a date column. I created a Derived column for date using the system date function in my Source data object and ran the package but it returned errors. I changed the data type of the derived column but I still get errors.
is there any other way i can get the date on the fly i.e generate a date for the incoming source file and map that (insert into) to the destination table ?
Thanks.
I am trying to figure out my expression here with derived column
source
Unavailable/Planned
output
Planned(which is after "/".
I achieved this in sql but not finding solution in SSIS Derived column transformation.
i have too many DTS packages to migrate to SSIS, and while examining a DTS package in BIDS (converted with the migration utility) i tried to edit the resulting migrated package, which opened the DTS interface with the two connection icons joined by the big fat arrow with a gear on it...not exactly what i had in mind, iow, it looks like SSIS on the outside, but its still DTS on the inside.
So I stripped out a series of components from a more complex package hoping that simplifying it would reveal the contents of old DTS Transformations tab at least partially set up in a Derived Column transformation.
Can i get there from here, or must i recreate every stinking definition in a derived column manually from the ground up?
thanks very much for your help

Hi,
I have dates in "mmddyy" format coming from the sources and they are older dates of mid 80s like 082580 for instance.
When I cast it this way (DT_DBTIMESTAMP) Source_Date , It says ok but throws a runtime error.
When I hardcode a date in same format, (DT_DBTIMESTAMP) "082580" , It becomes red (an indication of syntax error) . Please note that we use double quotes in expressions in Derived Column Transformation; So an anticipation that using double quotes over single ones would be the syntax problem would be wrong.
Any help in this will sincerely be appreciated.
Thanks

Hey all - got a problem that seems like it would be simple (and probably is : )
I'm importing a csv file into a SQL 2005 table and would like to add 2 columns that exist in the table but not in the csv file. I need these 2 columns to contain the current month and year (columns are named CM and CY respectively). How do I go about adding this data to each row during the transformation? A derived column task? Script task? None of these seem to be able to do this for me.
Here's a portion of the transformation script I was using to accomplish this when we were using SQL 2000 DTS jobs:
'**********************************************************************
' Visual Basic Transformation Script
'************************************************************************
' Copy each source column to the destination column
Function Main()
DTSDestination("CM") = Month(Now)
DTSDestination("CY") = Year(Now)
DTSDestination("Comments") = DTSSource("Col031")
DTSDestination("Manufacturer") = DTSSource("Col030")
DTSDestination("Model") = DTSSource("Col029")
DTSDestination("Last Check-in Date") = DTSSource("Col028")
Main = DTSTransformStat_OK
End Function
***********************************************************
Hopefully this question isnt answered somewhere else, but I did a quick search and came up with nothing. I've actually tried to utilize the script component and the "Row" object, but the only properties I'm given with that are the ones from the source data.
thanks in advance!

Can anyone show how to alter the value in a column using DerivedColumn component when creating an SSIS package programatically.
View 4 Replies View Related
Table structure as follows
Employee
Empno empname salary
commission
I want to have an other employee table named employee_modified
Empno empname salary
commission derived_column1(salary+commission)
derived_column2(derived_column1 + xxxx) and so on derive other
columns based on the earlier derived columns)
Is that possible to do it.. or am I doing something wrong.
something like
Select empno , empname , salary , commission,
(salary + commission) as derived_colum1 ,
(derived_colum1 + xxxxx) as derived_colum2 ,
(derived_colum2 + xxxxx) as derived_colum3
into employee_modified from employee
Hi All,
I'm pretty new with SSIS. I have written some custom component which will read from flat file and write it into database. Between those processes, there are other processes which will analyse and transform the data being transfered. Everytime, I remove a column from upstream component, I have to go through each component to fix up column reference mapping using Invalid Column References Editor. There are lots of clicking involves just to remove a column from upstream component. My package has about 15 components. I am just wondering, is there anyway for us to prevent that editor to pop up, instead fixing invalid column reference programatically in ReInitializeMetadata?
Thanks,
Will

Dear Friends,
In my controlFlow I have 2 sequence container... Sequence1 goes to Sequence2 if an expression valuate to TRUE.
If the expression value is true, than there isn's any problem and sequence2 runs, but if the expression is FALSE the sequence2 container doesn't run.
OK?
In the case of expression valueate to FALSE I need to generate an error or an information in order to get it in the eventhandler automatic...
I can add a script task to make the package failure... but what I insert in the precedence constraint editor from Sequence1 to the scripttask?
Imagine... the expression from Sequence1 to Sequence2 is a>=b
The expression from Sequence1 to ScriotTask os a<b? (How can I define this only to run when the expression (seq1 to Seq2) is false??
Someone know how?

Hi, how are you?
I'm having a problem and I don't know if it can be solved with a derived column expression. This is the problem:
We are looking data in a a sql database.
We are writting the SQL result in a flat file.
We need to transform data in one of the columns.
For example: we can have 3 digits as value in a column but that column must be 10 digit length. So we have to complete all the missing digits with a zero. So, that column will have the original 3 digits and 7 zeros. How we can do that tranformation? We must do it from de the flat file or it can be a previous step?
Thanks for any help you can give me.
