Map One Generic Input Column To Multiple Destination Column
Aug 7, 2007
I have a stored proc I am updating in an OLEDB Command from the results of a Transform Script Component. The Stored Proc has over 65 input parameters, most of them have a NULL passed in. I dont want to create output columns in the Transform Script Component for all of them to map them from the "Available Input Columns" to "Available Destination Columns".
I want to create 3 or 4 generic Output columns for their data type - say IntegerOutput (datatype Int), DateTimeOut (datatype datetime) and so on. The I want to map these generic columns in the OLEDB Command as Available Input Columns" to multiple "Available Destination Columns" - wherever the datatype matches the input column.
But the OLEDB Command Column Mappings let me map One to One only. This will create a huge and unnecessary workload for me to develop and maintain - when I tell you I have 3 such stored procedures, all of whose interfaces are exactly same and for which I can create similar Output columns in the Transform Script Component.
Hi, I was wondering how I can complete a column (which doesnt have an input one) with data. For example:
I have a sql query which bring data of 3 columns
ID | FISRT NAME | LAST NAME 1 MIKE MORGAN 2 SARA JOHANES
So, I will insert that data in a FLAT FILE CONNECTION MANAGER, which I configured with 3 columns and I did the corresponding mapping in the FLAT FILE DESTINTATION.
Now, If I add one more column in the FLAT FILE CONNECTION MANAGER, I will not have it mapped to a input one, obviously. So, what I need is to add one more column to the flat file destination and complete it with zeros values in it.
Probably I can solve this part by introducing a DERIVED COLUMN and there I can configure the zeros that I want to add to the column. But I'm not sure if I can do that without having a input column. So, the question will be, how can I add one column to a flat file which doesnt have a input and introduce any value that I want to it? Hope I was clear Thanks for your help.
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:
' 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.
This is a report I'm trying to build in SQL Reporting Services. I can do it in a hacky way adding two data sets and showing two tables, but I'm sure there is a better way.
TheTable Order# Customer Status
STATUS has valid values of PROCESSED and INPROGRESS
The query I'm trying to build is Count of Processed and INProgress orders for a given Customer.
I can get them one at a time with something like this in two different datasets and showing two tables, but how do I achieve the same in one query?
Select Customer, Count (*) As Status1 FROM TheTable Where (Status = N'Shipped') Group By Customer
I have a SQL Query issue you can find in SQL Fiddle
SQL FIDDLE for Demo
My query was like this
For Insert Insert into Employee values('aa', 'T', 'qqq') Insert into Employee values('aa' , 'F' , 'qqq') Insert into Employee values('bb', 'F' , 'eee') Insert into Employee values('cc' , 'T' , 'rrr') Insert into Employee values('cc' , 'pp' , 'aaa') Insert into Employee values('cc' , 'Zz' , 'bab') Insert into Employee values('cc' , 'ZZ' , 'bac') For select select col1,MAX(col2) as Col2,Max(Col3) as Col3 from Employee group by Col1
I have an OLE DB Command which updates a table. However, the command needs to use the value of an input column more than once.
For example I want to update TableA only if either ColumnA or ColumnB have actually changed: - update tableA set columnA = ?, column B = ? where columnC = ? AND (columnA != ? OR columnB != ?)
I can't map the Input column to more than one parameter so I've been forced to create a copy of columnA and ColumnB as input columns so I can map to the extra paramters that the Command shape expects.
I also attempted to modify the command syntax so it set up variables for the 3 values required and then set the values to parameters - but I get a very unhelpful syntax error message: - declare @ValueA varchar(50), @ValueB varchar(50), @ValueC varchar(50) select @ValueA = ?, @ValueB = ?, @ValueC = ?, update tableA set columnA = @ValueA , column B = @ValueB where columnC = @ValueC AND (columnA != @ValueA OR columnB != @ValueB)
Is it possible to assign to a column a value passed as a parameter?
When I run the proc I get the following error :
Msg 245, Level 16, State 1, Procedure Transfer, Line 17
Conversion failed when converting the varchar value '@ID' to data type int.

how to declare multiple derived columns in SSIS Derived Column Task in one attempt.as i have around 150 columns coming from Flat file. I had created the required Expression in Excel and now i want add those in derived column task but its allowing only 1 expression at a time.
I have worked with straight-forward simplistic SSIS up to now, so I apologize if this is a simple question. I have a SQL table destination that accepts daily data from an AS400 table. We now have a need to datestamp the incoming data so I added a new column to the destination table where I want today's date. Is there a data flow transformation that I need to use to default the destination column to today's date? Time is not a consideration and not needed, just the date.
I have a script component and under input columns, I checked one of the fields I want to use inside the script. It's under the Input 0 in the hierarchical tree inside the inputs and outputs.
I'm bothered by an issue of updating a column in input dataset from a update query. It looks like SSIS has a very poor function on this.
Example, I have an input dataset of name, salary, dept_no, and I have another table called departments which has fields of dept_no, Dept_name, basic_salary
now I want to update salary column in input dataset with basic_salary if it's salary is smaller than the basic_salary.
update #tmp set salary = basic_salary where #tmp.salary <departments.basic_salary and #tmp.dept_no = departments.dept_no
how could I impletement this in SSIS package?
I tried with lookup, modify scripts by enabling memory restriction. It doesn't say any error when I save the package, but I never get pass debug.
I'm developing a Destination Component. I need to create the input columns in my ReinitializeMetadata() method. This is a small code sample of the method:
This piece of code works fine, but now i want to use a UI Type DataFlowDestinationUI with a Destination mapping page added by base.AddDestinationMappingsPageToForm( form, "" );.
When I open the mapping page - ReinitializeMetadata() is called BEFORE opening this page - this error is shown:
Code Snippet =================================== Exception from HRESULT: 0xC0047041 (Microsoft Visual Studio) ------------------------------ Program Location: at Microsoft.SqlServer.Dts.Pipeline.Wrapper.IDTSVirtualInputColumn90.get_UsageType() at Microsoft.DataTransformationServices.DataFlowUI.DataFlowDestinationUI.mappingPage_MapColumns(Object sender, MapColumnsEventArgs args)
I think it's because the mapping page calls GetVirtualInput() itself. Do you know a solution for this problem?
I have been searching for the answer to something I thought would be easy to find. But, no luck.
I need to load a csv file into a SQL Server table. The rub is that I need to also parse the filename for a couple of pieces of data also. Example filename: c:importCustomerX_LocationY_1234.csv
For each record in the csv file I will call a stored procedure the has a parameter for each column in the file plus a parameter for the customer name and a colummn for the location name.
I assume that I will need to use a Script Component to parse the filename fro the information. What is not clear is how I get the filename from the csv connection object and how to get to result of the script component to the inputs of the OLE DB command component that I am using to call the stored procedure.
I have succeeded in using the Derived Column component to put constant values in for the customer and location. But, I cannot figure out how to get to the next step of deriving those two values from the input filename.
I am using Advantage ODBC 6.2 to connect to a Advantage Data Server to push data from a SQL table into this server. I can view the data from the ADS with DTS and I can insert data by using "Insert into TempTable ("Last Name","First Name") values ('test','test)" from a Execute SQL Statement. The issue is when I build up a DTS package to pull from SQL into the Advantage ODBC, I get a "missing closing ")"" error. I have narrowed it down to the column names in the destination table having spaces (Last Name, First Name, and a bunch of others. DBA 101 here). How do I beat this?
I have tried editing the destination column names in disconnected edit by adding the double quotes but get a "Column Name '"Last Name"' not found" error. Wrapping them with [] doesn't work. I think this is a limit on Advantage.
When I try to use Advantage OLE DB, I get an 'Ace32.dll must be newer then the other dll" error. I am afraid of upgrading Ace32.dll and not break other things.
So with this said my two questions:
How do I get the destniation column names wrapped in double quotes when using transformations?
or
Is there a way I can do an Insert into Advantage connection(column names) values (Select Values from SQL Server connection)?
I am loading files with same format from two different locations in to one database. First, my SSIS connects to location 1.
Lets Say Location1 : C:LoadFilesImport Location2 : D:LoadFilesImport
Location one has three different set files starting with
First Set: AP_1, AP_2,AP_3, Second Set: VD_1, VD_2, VD_3, Third Set: BK_1,BK_2,BK_3,
This SSIS set to run every 3 hours, if it finds files of any set load them. While loading it has to insert into a derivedcolumn called CustID. If the file name Starts with AP_ , custiD values should be as 101
AP_1 goes to Table1 AP_2 goes to Table2 AP_3 goes to Table3
If the file name Starts with VD_ , custiD values should be as 201 If the file name Starts with BK_ , custiD values should be as 301
after processing all these files in first location, the SSIS looks for files in second location and does the same?
--How to achieve CustID depending upon file name ?
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
I am having a little problem with a simple package and I do not know if this is a known issue or that I am missing something.
I have a data flow task, a simple one, with an oledb source pulling data, using a select statement, from a sql server 2005 instance, and an ole db destination pointing to a table in a sql server 2000 instance. Both intances are standard edition. The table in the destination has a column which allow null values and has also a default constraint (getdate()), and this column is not present in the source. When I map the columns in the destination, I leave this column as "ignore", not being mapped to any column from the source. The problem is that when I execute the task, SSIS is trying to insert NULL value into this column, so the package fail with the error "can not insert NULL value into column myColumn". I wonder why is it trying to insert NULL value if the column is not mapped to any column from the source.
Is this a known issue or I am nissing something in the settings?
If the destination table has rowversion or identity columns, there is no problem ar all. I ignore those columns in the mapping and SQL Server feeds them as expected.
I have created a package which transfers data from a SQL server source to an Excel Destination. The DataFlow Task works fine , if i pre-define the column names in the Excel Destination... But i run into an error when i give the blank excel sheet as my destination. I am unable to map any columns
A sample example is as shown above .. In the column mappings field only one column in the Excel shows up for mapping and eventually throws the error "[Excel Destination [42]] Error: The number of columns is incorrect. "
How do we proceed in this case , where in we do not want to give pre-defined coulmn names in the Excel Destination sheet.
I have an excel export with numeric values. When the SSIS package writes into the excel it treats all data types as strings and attaches an apostrophe in the beginning. I tried formatting the excel sheet with the number data type and saving it . It doesnt work.
Other strange thing is that when I go into the advanced editor for the excel destination and look into the properties of the external columns all of them have the data type as Unicode String[DT_WSTR] irrespective of what the data type is from the input.The UI allows me to change it to numeric for numeric columns without any error but the value is not saved at all which is very frustrating. I also tried changing it in the xml file of the package, it some how seems to overwrite it after validation. It would be really nice if it threw an error saying that it cannot be changed.
Anyways there seems to be no way of changing the destination data type if it s an existing file and if I create a new excel sheet there is no way of formatting data. Is there any way out?
how do I make the output columns padded with extra space ? I intentionally set my output width larger than the input width, but the generated file is still jamming all the columns next to each other
I have a excel file which has a column called "Code" and their values are A,B,C,D,E,F,G,H. I want to create a new column called "status" based on the values of "Code".
Code:
A B C D E F G H
If A,C,E,G then "status" = "Active" else if B,D,F,H then "Status" = "Inactive". I like to do it using "Derived Column".
I created a ssis package which exports the data from oledb source to flat file (csv format). For this i have OLEDB source and Flat File as destination. I generate the file and filename dynamically with the column names in the first row. So if the dynamically generated file name already exists , then i want to append the data in the same existing file. But I dont want to append the column names again. I just want to append the rows to the existing rows.
so lets say first time i generate a file called File1_3132008.csv.
Col1, Col2 1,2 3,4
After some days if my ssis package generates the same file name i.e. File1_3132008.csv, this time i just want to append the rows to the existing file. So the file should look like this- Col1, Col21,23,45,67,8
But instead my file looks like this if i set Overwrite propery to false
Col1,Col2 1,2 3,4 Col1,Col2 5,6 7,8
Can anyone help me to get the file as shown in the highlighed
I have a simple enough task to complete that I can€™t seem to find the answer to.
The task is this €“
Select table x from the database and write it to a flat file complete with that tables column headings.
Now I€™ve managed to set up an ole db datasource and selected the table and I€™ve also linked it to the flat file output. So now I can generate a flat file from the database. However no column headings appear in the flat file.
I can€™t seem to find anywhere (like a checkbox) that will also output the column headings to the flat file.
Now I can add in Headings manually in the properties of the Flat File Destination object but the columns that appear in the flat file don€™t appear to be in the order that I requested them in the SQL.
So the question is how do I automatically have the column headings appear for flat file output (ideally without me having to manually add them in).
If it can€™t be done and I have to use a vb.net script instead then would anyone have an example script of how to do it?
Thanks in advance for anyone who manages to answer this.
I was trying to get my data from olb table to excel. but i got this error my dataflow is as follows: oledb source-> excel destination
i have got a excel file template at the destination all ready. with the column names+ the sheet all ready. but somehow it got stuck... anybody can help? thanks!
