Hi,
In my data flow taks, The Source data is coming from AS400 has 4 columns,
I need to achieve the followings and require your help.
1. Generate a new column which will be combination of concating these 4 columns.
2. Need to add an extra row for Header & Footer.
Please Help.
I have a table like so
code remarks
1234 abcd
4567 efgh
I need to concatenate the values in the remarks column into one row like below
abcd, efgh....how is it possible
Hi all,
I have a scenario which I am not able to figure out how to do it better for quite some time.
Assume I have a few rows of data :
RunningID Date WOid
1234 1/23/2007 23
1236 1/24/2007 23
1239 1/2/2007 24
1222 1/4/2007 23
1321 2/4/2007 22
My objective is to merge all RunningID into a single cell when WOid is the same (this will most probably use a "group by" to get the different WOid out). Maybe some aggregate function that can do it as:
select ReturnConca(RunningID, "#") as RunningID_str, max(Date) as MaxDate, max(WOid) as WO from tableXXX
group by WOid
Results:
RunningID_str MaxDate WO
1234#1236#1222 1/24/2007 23
1239 1/2/2007 24
1321 2/4/2007 22
Any advise would be much appreciated.

I have three input columns from my flat file, defined as follows:

Now, what I want to do is pick the one that is populated, and put it into my table, in the column called

We are trying to use the Import/export wizard to load a text file to a SQL Server 2005 database. The input file has a variable number of columns per row. For example, the first row has 3 columns, the second has 7, the third has 3, etc. The number of columns varies from 2 to 9 in the input file. The columns are separated by an uptick (`) and the rows are terminated by {CR}{LF}. We are using code page 1252. On processing, the wizard reads the first row (with 3 columns) ok, but then assumes all the other rows have 3 columns and parses the rows accordingly, ignoring the field and row terminators.
The process worked fine with SQL Server 2000. Is there some setting that we are missing, or some configuration on the database that we should be checking?
Thank You
I'm using a Row Count Task to count the number of records passing thru a particular path in my data flow. I created a package variable and referenced this variable in the Components Properties tab in the Row Count Task. I believe this is the minimum I need to do to get the row count.
However, as I explore the other tabs in the editor, I see there is something called Input Columns tab. What is this for? I didn't select anything in there and things are working fine. At first I thought that I had to choose the columns that I want to have available to me for further processing after the Row Count Task, but this isn't the case. I am able to see all my columns coming out of the Row Count Task even tho I didn't do anything in the Input Columns tab.
So, what is this setting for?
Can anyone please help

Hi,
I have an SSIS Package. I am using script component to loop through input columns and their values. I am not able to do Null checking. The code is as below. In place of dashes , I want to do null checking but am not able to do. I tried vbNull, IsNull, TypeOf, System.dbNull but nothing is working. I guess am missing something here. Can anyone help me with this.
For Each column In Me.ComponentMetaData.InputCollection(0).InputColumnCollection
columnValue = rowType.GetProperty(column.Name)
If Not --------------- Then
RowData += ((FormatElement(column.Name) + ReplaceSpecialChars(columnValue.GetValue(Row, Nothing).ToString()) + FormatElement(column.Name, True)))
End If
Next
Thanks in Advance.
Is there by chance a cunning way to make the input columns automatically populate the output of an asynchronous script transformation?
My transformation writes several rows for each input row read. I'm creating some new columns along the way but I'd like all of the input columns to get output each time also. However I can't see any obvious way to achieve this, short of manually defining each column to the output and populating it in the script.
I have set up a script task in one of my packages that I have set up to modify another package right before running it. This package is nothing more than a data flow task that transfers rows via an sql command from one table into another. The strange thing is I have gotten it to work with some tables but not with others. T
he script bombs out in the loop where i map all of the columns found below, where i use MapInputColumn with the error HRESULT: 0xC0010009 On Microsoft.SqlServer.Dts.Pipeline.Wrapper.IDTSExternalMetadataColumnCollection90.get_Item(Object Index)
The thing is this happens after looping roughly 55 times but there are still about 100 columns that it needs to loop through still.
Code Block
Dim input As IDTSInput90 = data_destination.InputCollection(0)
Dim virtual_input As IDTSVirtualInput90 = input.GetVirtualInput
Dim input_column As IDTSInputColumn90
Dim virtual_column As IDTSVirtualInputColumn90
' Iterate through the virtual input column collection and map field names
For Each virtual_column In virtual_input.VirtualInputColumnCollection
input_column = inst_data_destination.SetUsageType(input.ID, virtual_input, virtual_column.LineageID, DTSUsageType.UT_READONLY)
inst_data_destination.MapInputColumn(input.ID, input_column.ID, input.ExternalMetadataColumnCollection.FindObjectByID(virtual_column.Name).ID)
Next
Just for kicks i removed the mapping portion of the code and left in the SetUsageType to see if it would update the available input columns in the destination. The script will then finish successfully but still only the 55 or so fields out of 155 are available in the input. So i then stepped through the script with the mapping portion still disabled and after it loops successfully, i call reinitialize meta data and it produces an error in the input_column variable: HRESULT: 0xC0047041.
I find it odd that this still reports to me that the script finished successfully and I also find it odd that this works fine on two other tables I've tested but not this one. Any insight would be greatly appreciated.
Hi, all experts here,
Thank you very much for your kind attention.
I got a strange problem with SQL Server 2005 data mining models though. I have selected the input columns for my mining model (which are different from the input columns for its mining structure, since I ignored some of the columns for the selected model). But the mining model still used all input columns from the mining structure rather than those I chose for the mining model.
Would please any one here give me any guidance and advices for that. Really need help for that.
Thanks a lot in advance for any help.
With best regards,
Yours sincerely,
Hi,
In a SSIS Data flow task, whatever you are doing with the input columns that come from a Data source like a Flat File Source, these columns are always visible and available as input columns for all Transformation and Destination components in the Data flow.
Our Custom Component is a column mapping component that transforms many input columns into many oputput columns and we would like that the used input columns are not available anymore to the downstream components...
Is that possible?
I saw that with the Unpivot component it is possible to make some input columns unavailable to downstream components...So I think there is a way to do the same in a custom component...
Thanks for any help,
David
I am building an SSIS package that loops through a table in SQL Server and dynamically builds a select statement that i would like to use as an ole db source. I have been having a difficult time with this as the select statement that i am generating is over 200,000 characters long so using an sql variable is out of the question.
I ended up placing the select statement into a table where each row of the table represents a piece of the select. I then use an execute_sql task that selects the entire rowset from this table into a variable object. I then use a for each loop to shred the variable and concatenate it into on big string variable called user:: sql_statement that is my select.
After setting up the loop and testing to see if the user:: sql_statement variable populates correctly i then added a data flow transfer with an ole db source and destination. I then go into the advanced editor for the source and set it to accept an sql statement from a variable and use my user:: sql_statement variable. I was forced to set validate external metadata option to false to avoid an error since there is no way to validate the columns until the for each loop runs during run time.
Now thats all fine and good but what is causing my problem is that during run time, when the package gets to the data flow task, the select statement doesn't seem to be populating the input columns of the data source. I have been searching to no avail on a way to tell the data source to update the input columns but every time it gets there, the package bombs out telling me the ole db source has no available output columns.
Specifically the error i get is :
[DTS.Pipeline] Error: "output "OLE DB Source Output" (6616)" contains no output columns. An asynchronous output must contain output columns.
Any help with this would be much appreciated.
Hi,
i have a table like below

5 6 9 5 5 9
i want to write a stored procedure where i pass column names a parameters and i want to get result based on that
For ex:-
if i pass the parameters as
col3 and col5 where id =1 then i should the result as
id col3 col4 col5
1 3 4 5
and if i pass input as col2and col6 where id =3, the result should be
id col2 col3 col4 col5 col6
3 4 8 2 6 9
can anyone help on this??
I'm trying write a reusable script component that takes data from rows that were rejected from a SQL Destination operation and put them into a common SQL error table.
This script would basically function to take the input columns selected in the script, and build a delimited string, (similar to the 'Flat File Source Error Output' that is contains redirected rows from reading a flat file) and insert this string into a SQL table called 'SourceData' to store errors.
I'm trying to script the component to iterate through all input columns (as selected in the input columns screen) and build a simple string.
Code Block
Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)
'Use the incoming error number as a parameter to GetErrorDescription
Row.ErrorDescription = ComponentMetaData.GetErrorDescription(Row.ErrorCode)
Try
Row.ErrorColumnName = ComponentMetaData.InputCollection(0).InputColumnCollection(Row.ErrorColumn).Name
Catch ex As Exception
Row.ErrorColumnName = String.Concat("Column Name retrieval failure. Details", ex.Message)
End Try
'
'Build input data
'
Dim inData As String
For Each inputCol As IDTSInputColumn90 In ComponentMetaData.InputCollection(0).InputColumnCollection
inData = String.Concat(inData, "~", inputCol.Name) 'I don't want the name, but the value.
Next
Row.SourceData = inData
'
End Sub
I've only got as far as iterating the names of columns in the input buffer, but how do i get the values?
The result i'm trying to achieve is :
Selected columns in 'Input Column' screen : Name, Address, Phone
OutPut column 'SourceData' value : Harry~Melbourne~None
I don't want to write the code as:
Code Block
inData = Row.Name
indata = String.Concat(inData,"~",Row.Address)
indata = string.concat(inData,"~",Row.Phone)
as this make my code not very reusable. I've got some tables which are 100+ columns long and I don't wish modify the code too much
I have also tried overriding the ProcessInput() function of the script component to iterate through the buffer columns :
Code Block
Public Overrides Sub ProcessInput(ByVal InputID As Integer, ByVal Buffer As Microsoft.SqlServer.Dts.Pipeline.PipelineBuffer)
MyBase.ProcessInput(InputID, Buffer)
Dim iCnt As Integer = 0
Dim inData As String
If Buffer.ColumnCount > 0 Then
For iCnt = 0 To Buffer.ColumnCount - 1
inData = String.Concat(Buffer.Item(iCnt)) 'Error thrown here: PipelineBuffer has encountered an invalid row index value.
Next
End If
End Sub
but i get an error when i run it.
Please help.
Hi All,
I want to run a loop for all the input columns in the script component. My requirement is, I have nearly 50 columns in the input columns list. For each row and for each column I need to do some operation. How Can I run a loop for each column. Please note in the script component I need to get the column names in the middle for some operations. Please see below.
Process Each Input Row
For each column in Input column list
....
....
If column.Name Starts with "Test" then set NULL to the column value
....
....
End Loop
End Loop for each input row
Can anybody tell me how can I do that.
Regards
Venkat.
In SSIS I use the DQS Cleansing transformation component. I've got a knowledge base (KB) in place and this KB holds various domains and my data source has more input columns than would like to use for a particular clean up operation. I want to use some of the input columns to map against some domains in the KB. It is my understanding that it should be possible to select only the required input columns, but all i can do is select all input columns.

I'm trying to create a fairly simple custom transform component (because I've read that's the easiest one to create) which will take one column from a flat file source and based on the first row create the output columns.
I'm actually trying to write a component that will solve the now well known problem with parsing CSV files in SSIS. I have a lot of source files and all have many columns so a component that can read in the first line from the CSV file and create the output columns automatically will save me lots of time when migrating the old DTS packages.
I have the basic component set up but I'm stuck when trying to override the OnInputPathAttached method because I don't know how to use the inputID to get the first line from the input (the buffer).
Are there any good examples for creating output columns dynamically based on the input buffer?
Should I just give up on on the transform and create a custom source component instead?
I concatenate multiple rows from one table in multiple columns like this:
--Create Table
CREATE TABLE [Person].[Person_1](
[BusinessEntityID] [int] NOT NULL,
[PersonType] [nchar](2) NOT NULL,
[FirstName] [varchar](100) NOT NULL,
CONSTRAINT [PK_Person_BusinessEntityID_1] PRIMARY KEY CLUSTERED
[Code] ....
This works very well, but I want to concatenate more rows with different [PersonType]-Values in different columns and I don't like the overhead, of using the same table in every subquery ([Person_1]). Is there a more elegant way to do this, without using a temp table or something else?

I have a table with 10 rows with a varbinary column
I wish to concatenate all the binary column into a single binary column and then write that to another table within the database. This application splits a binary file (Word or PDF document) into multiple segments (this is Column2 as below)
example as follows
TableA
Column1 Column2 Column3
aaa 001 <some binary value>
aaa 002 <some binary value>
aaa 003 <some binary value>
aaa 004 <some binary value>
aaa 005 <some binary value>
desired results in TableB
Column1 Column2
aaa <concatenated value of above binary columns>
While recently working with several mining models, I came across something that struck me as pretty odd - and I'm hoping to find an explanation for the behavior.
Consider the following setup:
A single table in the relational database represents the only case table
A single, continuous column is the predictable
A mining structure has been created
The mining structure contains a single model, based on the MS Decision Trees algorithm
Input columns were selected for the model via the BI Studio wizard (i.e., those provided via the "Suggest" button)
The structure has been fully processed
Now, the interesting parts:
I view the scatterplot for the mining model, under the Mining Accuracy Chart tab
Back on the Mining Structure tab, I delete one of the input columns
I add the same column back into the structure
The structure is fully processed again
When I view the scatterplot for the mining model, under the Mining Accuracy Chart tab, a different set of data points are presented for the model predictions
A different set of decision trees under the Mining Model Viewer tab confirms thisHow could different patterns have been found this second time around, even though all of the input columns were the same (as well as the training cases)?
(Note: I encountered this situation while creating a new mining model that was identical to an existing one. Even though the models received the exact same inputs and training cases, they yielded different results. I was able to reproduce the behavior by using steps 1-6 above, though.)
Can someone provide some insight on this behavior, or some kind of explanation of what may be happening?
Thanks,

I need to loop the recordset returned from a ExecuteSQL task and transform each row using a Data Conversion task (or a Script Task).
I know how to loop the recordset returned by an ExecuteSQL task:
http://www.sqlis.com/59.aspx
I loop the returned recordset (which is mapped to a User variable of type System.Object) and assign the Variable Mappings in the ForEach Loop to different user variables which map to the Exec proc resultset (with names and data types).
I assume to now use these as the Available Input columns for the Data Conversion task, I drag a Data Flow task inside the For Each Loop container and double-click it, then add a Data Conversion task.
But the Input columns (which I entered in the Variable Mappings in the ForEach Loop containers) dont show up in the Available Input columns of the Data Conversion task.
How do I link the Variable Mappings in the ForEach Loop containers from the recordset returned by the Execute SQL Task to the Available Input columns of the Data Conversion task?
.......................
If this is not possible, and the advice is to use the OLEDB data flow as the input for the Data Conversion task (which is something I tried too), then the results from an OLEDB Command (using EXEC sp_myproc) are not mapped to the Available Input columns of the Data Conversion task either (as its not an explicit SQL Statement and the runtime results from a stored proc exection)
I would like to use the ExecuteSQL task to do this as the Package is clean and comprehensible. Which is the easiest best way to map the returned results from a Stored proc execution to the Available Input columns of any Data Flow transformation task for the transform operations I need to execute on each row of data?
[ Could not find any useful advice on this anywhere ]
thanks in advance!
Hello:
I am running into an issue with RS2k PDF export.
Case: Exporting Report to PDF/Printing/TIFF
Report: Contains 1 table with 19 Columns. 1 column is static, the other 18 are visible at the users descretion. Report when printed/exported to pdf spans 2 pages naturally, 16 on the first page, 3 on the second, and the column widths have been adjusted to provide a perfect page span .
User A elects to hide two of the columns, and show the rest. The report complies and the viewable version is perfect, the excel export is perfect.. the PDF export on the first page causes every fith column, starting with the last column that was hidden to be expanded to take up additional width. On the spanned page, it renders the first column on that page correctly, then there is a white space gap equal to the width of the hidden columns and then the rest of the cells show with the last column expanded to take up the same width that the original 2 columns were going to take up, plus its width.
We have tried several different settings to see if it helps this issue or makes it worse. So far cangrow/canshrink/keep together have made no impact. It is not possible to increase the page size due to limited page size selection availablility for the client. There are far too many combinations of what the user can elect to show or hide to put together different tables to show and hide on the same report to remove this effect.
Any help or suggestion on this issue would be appreciated
