Ho Do I Get The Details From A DTS Transform Data Task Into An SSIS Derived Column Transformation?

Mar 7, 2008

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

SSIS - Derived Column Transformation

Feb 7, 2008

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

SSIS - Derived Column Transformation Editor Expression

Aug 23, 2007

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?

REPLACE In Derived Column Transform Causing Repeat Data In Rows That Should Be Blank

Jul 25, 2006

W2k3 server, SQL 2005.
@@version = Microsoft SQL Server 2005 - 9.00.1399.06 (Intel X86)
Standard Edition on Windows NT 5.2
(Build 3790: Service Pack 1)

I have my first SSIS package almost working, but I'm having an odd problem and can't find any information to help resolve it.

I'm importing from a flat file (csv) to an existing table (append). I've got a Derived Column transformation in the middle to do some data cleanup. It's all working except for one little problem...

One of the transformations is 'REPLACE([Column 3],"^","; ")', output to a new column. (The input file has a field that uses carets as delimiters between an unknown number of items; I'm changing that to semicolons for easier reading.) Not all rows have data in this column, some will have one item, some will have multiple items.

The REPLACE works except that it fills in repeated data for all the blank rows.

Example:

Incoming data is:

1 Smith,Jane^Jones,Jane

2 Brown,John

3

4 Adams,James^Adams,Jim

5

6 White,Debra

Data inserted into the table is:

1 Smith,Jane; Jones,Jane

2 Brown,John

3 Brown,John

4 Adams,James; Adams,Jim

5 Adams,James; Adams,Jim

6 White,Debra

I've tried to use a Conditional to skip the empty rows, but I can't get that working at all (get syntax errors no matter what I put in).

Any suggestions on how to fix this would be most appreciated!

Thank you.

SSIS Equivalent To DTS Transform Data Task Properties

May 3, 2007

I am trying to read in a flat file, transform the fields and store into a destination database.



In DTS, this works using Transform Data Task Properties. I define the columns and then have a VB script on the Transformations tab that changes any bad data.



Is there a way to do this in SSIS that I can define the column transformations and re-use my VB scripts?

Conditional IF In A Derived Column Transform

Apr 12, 2006

HI, I was wondering if there is a possibility to use a confitional if like this:

IF(ISNULL(mycolumn value, "new value if null", mycolumnvalue)

into a derived column transform to infer a value to a null column value. I do know I can do it using a script component by it would be simpler to do by using an expression.

Thank you,

Need Alternative To PATINDEX In Derived Column Transform

Oct 30, 2007

Hello,
I understand that it is not possible to use PATINDEX in a Derived Column transform. I'm trying to eliminate leading zeros from a column where the string is always 14 characters long, but the first non zero character could occur any number of characters from the left of the string. The following achieves what I need:


substring([Account No w/0s], patindex('%[^0]%', [Account No w/0s]), 14) AS ExtractedAcctNo


Does anyone happen to know how I might express this differently in a Derived Column transform? Should I consider a calling a function through an OLE DB Command transform on each row instead? Maybe I should have a SQL Task that runs an UPDATE statement against the column.

Thank you for your help!

Cast/Convert Mmddyy In String To New DB_DATETIMESTAMP Column In Derived Column Transformation

Mar 5, 2007

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

Extending Derived Column Transform With Custom Function Library

Feb 16, 2007

When data is imported from our legacy system, the same functions need to be applied to several columns on different tables. I want to build a kind of "Function Library", so that the functions I define can be re-used for columns in several packages.



The "Derived Column" transform seems ideal, if only I could add my list of user-defined functions to it. Basically I want to inherit from it, and add my own list of functions for the users to select.

Is this possible ?

What other approaches could I take to building about 30 re-usable functions?

but while transfering record from text file to table i need some logic here

my text file is
"ID"|"Name"
1012|"10AA"
1013|"10BB"

logic is 10 should be replace by variable VID = 98

I defined this veriable as int

My ID column in database is int and Name column is varchar(50)

I try here expression like
ID != 98 ? @[User::VID] : ID
it work fine

but for varchar column I am not able to do
I got error when i write expression
SUBSTRING(Name,1,2) != "98" ? [DT_STR, 50, 1252] "(@[User::VID])" + rest of value of column : [Name]

my final output in table should be like
ID..Name

Help Me With Derived Column Transformation

I have this expression
(Registered_Units == Limited_Units) ? 0 : (Painted_Units / (Registered_Units - Limited_Units)) * 100)

It gives me 0.00, although those 3 columns have values.

if I cast it like this

(Registered_Units == Limited_Units) ? 0 : ((((DT_DECIMAL,2)Painted_Units) / ((DT_DECIMAL,2) (Registered_Units - Limited_Units))) * 100)

It gives me correct answer in whole number but .00 after decimal.

Derived Column Transformation

Sep 20, 2007

Hello.
I am using Derived Column transformation for calculating the age of individual and then adding the column to my final destination. In SQL, the DOB is varchar(50) and the output column I am creating should be Integer.
Here is the expression I am using for calculating the age:
(DATEDIFF("DAY",(DT_DBTIMESTAMP)TRIM(DOB),(DT_DBTIMESTAMP)TRIM([Service Date])) / 365.25)

In SQL, I have no problems getting the age of a person, but I am having difficulties using Derived Column Transformation.
I get the following error when executing my package:

Error: 0xC0049067 at Data Flow Task, Derived Column [2086]: An error occurred while evaluating the function.Error: 0xC0209029 at Data Flow Task, Derived Column [2086]: SSIS Error Code DTS_E_INDUCEDTRANSFORMFAILUREONERROR. The "component "Derived Column" (2086)" failed because error code 0xC0049067 occurred, and the error row disposition on "output column "_AGE" (2877)" specifies failure on error. An error occurred on the specified object of the specified component. There may be error messages posted before this with more information about the failure.

How To Assign User Variable Value To The Derived Column, In Data Flow Task

Dec 19, 2006

Hi:

In the derived column transformation editor, I have a Derived column name called FileGroupID. I would like to pass in a value for this column from a variable that I have set earlier in the scope. Can someone let me know, how to write the expression that does that and where do I specifiy that expression. I am thinking its the expression field in the derived column transformation editor. My main question is how to actually write the expression, what is the syntax to pull the variable value? Thanks.

Moving Files (split From An Existing Thread-SSIS Equivalent To DTS Transform Data Task Properties)

May 7, 2007

Hi JayH (or anyone). Another week...a new set of problems. I obviously need to learn .net syntax, but because of project deadlines in converting from DTS to SSIS it is hard for me to stop and do that. So, if someone could help me some easy syntax, I would really appreciate it.



In DTS, there was a VBScript that copied a set of flat files from one directory to an archive directory after modifying the file name. In SSIS, the directory and archive directory will be specified in the config file. So, I need a .net script that retrieves a file, renames it and copies it to a different directory.

Linda



Here is the old VBScript Code:

Public Sub Main()

Option Explicit

Function Main()

Dim MovementDataDir

Dim MovementArchiveDataDir

Dim MovementDataFile

Dim MovementArchiveDataFile

Dim FileNameRoot

Dim FileNameExtension, DecimalLocation

Dim CurMonth, CurDay

Dim FileApplicationDate

Dim fso ' File System Object

Dim folder

Dim FileCollection

Dim MovementFile

'======================================================================

'Create text strings of today's date to be appended to the archived file.

FileApplicationDate = Now

CurMonth = Month(FileApplicationDate)

CurDay = Day(FileApplicationDate)

If Len(CurMonth) = 1 Then

CurMonth = "0" & CurMonth

End If

If Len(CurDay) = 1 Then

CurDay = "0" & CurDay

End If

FileApplicationDate = CurMonth & CurDay & Year(FileApplicationDate)

'=====================================================================

' Set the movement data directory from the global variable.

MovementDataDir = DTSGlobalVariables("gsMovementDataDir").Value

MovementArchiveDataDir = DTSGlobalVariables("gsMovementDataArchiveDir").Value

fso = CreateObject("Scripting.FileSystemObject")

folder = fso.GetFolder(MovementDataDir)

FileCollection = folder.Files

' Loop through all files in the data directory.

For Each MovementFile In FileCollection

' Get the full path name of the current data file.

MovementDataFile = MovementDataDir & "" & MovementFile.Name

' Get the full path name of the archive data file.

MovementArchiveDataFile = MovementArchiveDataDir & "" & MovementFile.Name

DecimalLocation = InStr(1, MovementArchiveDataFile, ".")

FileNameExtension = Mid(MovementArchiveDataFile, DecimalLocation, Len(MovementArchiveDataFile) - DecimalLocation + 1)

FileNameRoot = Mid(MovementArchiveDataFile, 1, DecimalLocation - 1)

MovementArchiveDataFile = FileNameRoot & "_" & FileApplicationDate & FileNameExtension

If (fso.FileExists(MovementDataFile)) Then

fso.CopyFile(MovementDataFile, MovementArchiveDataFile)

' If the archive file was coppied, then delete the old copy.

If (fso.FileExists(MovementArchiveDataFile)) Then

fso.DeleteFile(MovementDataFile)

End If

End If

Next

fso = Nothing

folder = Nothing

FileCollection = Nothing

Derived Column Transformation Editor

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.

Error On Derived Column Transformation

May 20, 2008


Hi all€”Given a date field called [Reading Date] and a time field called [Reading Time], I am attempting to use the following transformation on the field to test for nulls and combine the data into a single field called [Reading Date/Time]:

(DT_WSTR)([Reading Date]== "") || ISNULL([Reading Date]) || (DT_WSTR)([Reading Time]== "") || ISNULL([Reading Time])? (DT_DBDATE)GETDATE() : (DT_DATE)(SUBSTRING((DT_WSTR,8)[Reading Date],5,2) + "/" + SUBSTRING((DT_WSTR,8)[Reading Date],7,2) + "/" + SUBSTRING((DT_WSTR,8)[Reading Date],1,4) + " " + SUBSTRING((DT_WSTR,8)[Reading Date],1,8))

I get the following error:

Error at Data Flow Task [Derived Column1[177]]: Attempt to parse the expression "(DT_WSTR)([Reading Date]== "") || ISNULL([Reading Date]) || (DT_WSTR)([Reading Time]== "") || ISNULL([Reading Time])? (DT_DBDATE)GETDATE() : (DT_DATE)(SUBSTRING((DT_WSTR,8)[Reading Date],5,2) + "/" + SUBSTRING((DT_WSTR,8)[Reading Date],7,2) + "/" + SUBSTRING((DT_WSTR,8)[Reading Date],1,4) + " " + SUBSTRING((DT_WSTR,8)[Reading Date],1,8))" failed. The expression might contain an invalid token, an incomplete token, or an invalid element. It might not be well-formed or might be missing part of a required element such as a parenthesis.

Here is a sample [Reading Date]:
05/07/08

Here is a sample [Reading Time]:
19:45:48

I need to be able to handle exceptions if one or both contain NULL or no data at all. Any suggestions on how to fix this?

Thanks,
Jon

Derived Column Transformation Expression

Mar 7, 2006

Hi.

I am using the following expression to check if the first charcter of a string is not the letter "E" and if it is, strip it off by selecting the remainder of the string:

SUBSTRING([Derv.comno],1,1) == "E" ? SUBSTRING([Derv.comno],2,10) : [Derv.comno]

This is ok in 99.9% of cases, but ideally I would like to be able to check, and alter the string if the first charcter is anything but numeric

I had something like this in mind:

SUBSTRING([Derv.comno],1,1) != ("1","2","3") ? SUBSTRING([Derv.comno],2,10) : [Derv.comno] 

but the syntax is incorrect.

Could you tell me if what I am attempting is actually possible, and if so, point me in the right direction regarding the syntax!

Thanks

Using User Variables In Derived Column Transformation

Apr 24, 2006

My derived column transformation with a user variable expression displays the user variable's default and not its assignned value.

Background: I built a script component that seems to effectively assign a new value to a user variable. I use local variables within the component, make the assignment in the PostExecute subroutine, and check by writing the user variable to a messagebox there.

In the derived column transformation I create a new column and insert the user variable in its expression field, add a data viewer, and send it to a data destination. The data viewer shows the user variable default and not the assignned value.

I replaced the user variable with a system variable in the expression field and that works fine.

Have folks successfully used this scenario before? Any ideas? Thanks.
