HOW TO: Create Dynamic Excel Destinations
Jun 22, 2006
I have a ForEach Loop Container that is running from a Foreach ADO Enumerator with records telling me which companies have records to export. As I loop through I use a data flow task to export the records to Excel, I want to create separate Excel files using some of the parameters from my recordset as parts of the name.
I have DelayValidation=True for my DFT and my Excel Connection Manager, ValidateExternalMetaData=False for my Excel Destination Adapter, and an expression setting the ExcelFilePath and ServerName properties to the dynamic path & file name from variables.
The layout will be the same (i.e. metadata) for each file. The files are just getting broken up by company and service type and I want to use that in naming the files.
I am currently getting the following errors:
[EX_DST New Enrollments File [238]] Error: An OLE DB error has occurred. Error code: 0x80040E37.
[EX_DST New Enrollments File [238]] Error: Opening a rowset for "NewEnrollments$" failed. Check that the object exists in the database.
[DTS.Pipeline] Error: component "EX_DST New Enrollments File" (238) failed the pre-execute phase and returned error code 0xC02020E8.
What do I have to do to create the new Excel File? I thought it would do it when the properties were set. Do I have to create the "table" for the worksheet named "NewEnrollments"? If so, how do I accomplish it.
Thanks in advance.

I have a dynamic flat file I need to import to a table (in the same format as the file). The problem, I'm realizing, is that dynamic column mappings are a pain with SSIS. I have to know the format of the flat file ahead of time, which I won't.
What are my options here? Can package configurations help with this?

Hi Craig/Kamal,
I got your email address from your web cast. I really enjoyed the web cast and found it to be
very informative.
Our company is planning to use SSIS (VS 2005 / SQL Server 2005). I have a quick question
regarding the product. I have looked for the information on the web, but was not able to find
relevant information.
We are getting Source data from two of our client in the form of Excel Sheet. These Excel sheets
Are generated using reporting services. On examining the excel sheet, I found out that the name
Of the columns contain data itself, so the names are not static such as Jan 2007 Sales, Feb 2007 Sales etc etc.
And even the number of columns are not static. It depends upon the range of date selected by the user.
I wanted to know, if there is a way to import Excel sheet using Integration Services by defining the position
Of column, instead of column name and I am not sure if there is a way for me to import excel with dynamic
Number of columns.
Your help in this respect is highly appreciated!
Thanks,
Hi Anthony, I am glad the Web cast was helpful.
Kamal and I have both moved on to other teams in MSFT and I am a little rusty in that area, though in general dynamic numbers of columns in any format is always tricky. I am just assuming its not feasible for you to try and get the source for SSIS a little closer to home, e.g. rather than using Excel output from Reporting Services, use the same/some form of the query/data source that RS is using.
I suggest you post a question on the SSIS forum on MSDN and you should get some good answers.

So my question is, is there any way to create a new table based on the excel file selected including the column name in SSIS? So that l can use the data reader as source to select those columns l am interested on and start the integration.
Thanks.

Please help....
I have different files that are sent from our vendors. Some are TXT and some are XLS. Some will have the same structure. I plan on grouping these together as best as I can.
My main problem is that I would like to go from one source that matches a group of files to a single SQL table. I'm still learning about SSIS and its capabilities. If I can get pointed in the right direction or have an example to work from, that would be great.
I've tried googl'ing to find some step by step, examples, and hints to do this right, but so far I'm at a bit of an impasse.
Thanks,
Dave

Hi All, i've been reading this article http://rafael-salas.blogspot.com/2006/12/import-header-line-tables-_116683388696570741.html
in regards to creating an excel spreadsheet dynamically in SQL Server 2005 SSIS. However, i'm constantly getting an where the tab is created but not being populated. Can somebody post up a clearer example?
The problem I'm trying to solve is to automate the export of a query onto a new dynamic spreadsheet each time I run this SSIS package.
Any help would be greatly appreciated.

Hi,
Trying to dynamically set the connectionstring property of the excel source.
This is what I enter instead of the hardcoded excel file paths:
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + @[User::FileName] + ";Extended Properties=Excel 8.0;HDR=YES"
I get this error, every time I set the delay validation property of the dataflow tab to true.
Cannot detach from one or more processes.
The object invoked has disconnected from its clients
Do you want to terminate them instead?
Thanks

This method has worked beautifully for all my SSIS pkgs thus far.
Basically, I use a Script Task to derive the name of the newest file in a local directory. Then I save the name of the file to user a user variable, e.g. User::File.
Then, in my flat file properties > Expressions, I set "ConnectionString" to reference User::File.
However, when attempting to use this method with an Excel source, I get this error message:
Error at myPkg [Connection manager "Excel Connection Manager"]: The connection string format is not valid. It must consist of one or more components of the form X=Y, separated by semicolons. This error occurs when a connection string with zero components is set on database connection manager.
Error at myPkg: The result of the expression "@[User::Folder]+ @[User::File]" on property "ConnectionString" cannot be written to the property. The expression was evaluated, but cannot be set on the property.
HELP......... I need this to work!
Thanks

I set up a external data connection to a reporting services report via excel but because my report is paginated it will only retrieve data for the first page. Is there a way to make the report render on 1 page only?
or is there an easier way to do what i'm trying to do?

I know that this is an Excel question, but I guess it is much more likely that an SQL person using dynamic pivot tables had stepped on this, rather than any advanced Excel user.
I am exporting a dynamic pivot table to Excel through a Stored Procedure. If the Stored Procedure that executes the dynamic pivot table returns 7 columns in one run, and 4 columns in the following update, then I have 3 orphaned columns that are still displayed in the spreadsheet. There isn't any content related to them, but the empty columns with their headers are bothering enough.
I've been trying to play with the data connection properties, but nothing deletes unused columns from former data executions.

I need to take 5 or 6 select statements to excel. Here are my limitations...
- each of the queries (thankfully) have the same data format
- each of the queries could return more than 65k, so a new worksheet needs to be generated dynamically.
- the names of the excel worksheets need to be custom, but a naming scheme would have to be developed for queries that ran over into multiple worksheets.
What's the smartest way to do this?
I'm having a hard time getting my head around this. I would love any help... I know I'm not breaking any new ground here. I've found pieces of what I'm doing on lots of forums, but never the exact thing. The complexities compound quickly when dealing with dynamic excel worksheets. =)

Hi all,
I did a few searches but did not find this specific scenario. Can anyone state with confidence whether this is possible (and if so, how)? Scenario:
-One table with a couple million rows (one column indicates which Country the record belongs to)
-Need to create an Excel 2007 file dynamically (for each Country) using SSIS 2005. Filename should include the Country Name (Sweden_Affliliated.xlsx). I have a table that contains a distinct list of all the countries. Each worksheet will have the same structure / schema across all files.
What seems to be working:
**I understand how to use an Execute SQL task to get the list of Country Names and bind to an object variable.
**I understand how to set variable mappings for a String variable to contain the "current Country" in a ForEach Loop.
**I understand how to set the OLE DB Data Flow Source to use a SQL command from a String variable that has the CountryName dynamically embedded within it.
**I understand I need to convert my varchar to Unicode using a Data Conversion task in my scenario.
**I understand that in order to write to an Excel 2007 file I need to use an OLE DB Destination with an Extended Property value of "Excel 12.0" and the ServerName property should contain a path to the file with no quotation marks.
Problems I have:
**OLE DB Destination: How do I set up the mappings when the file does not exist yet?
What I want to avoid, is having to create a template source XLSX file and using a File Copy task (I have gone this route before, but it would be best if I did not require a template). Is there a way to configure the SSIS package without using a File Copy Task? Creating the Excel file on the fly?
Thanks for any assistance in advance,
Brian

Hi,
I've seen a number of posts similar to this but i still cannot figure out what i need to do to get it working. So here goes with a couple of newbie questions.
Question 1:
Once created how do i go about executing a SSIS package. I want to be able to call it from a C# application from which i pass in a couple of parameters?
Question 2:
How do i go about setting the file path of my Excel source to a dynamic value passed at runtime. I want to be able to loop through a number of Excel files and do some processing on them. I've set up a variable (which i think i need to do) after that i get stuck however. Some other posts suggest configuration packages but i cannot get my head around how they work?
Any help on this matter would be gratefully recieved.
Thanks in advance,
Grant

Folks,
I am running into an issue while trying to export data to a spreadsheet. I actually don't know how to do it... Considering I only know the column names by the time I execute my procedure, I can't use the Excel Destination to export data.
With DTSs I would create an ActiveX script to execute the procedure which loads the results into a temp table. After that I would select everything from this temp table and load the results into a record set, looping through this record set to create the destination spreadsheet with the dynamic column names.
When it comes to SSIS we are advised to write vb.net scripts instead of ActiveX... These ones do not have records set's but dataset's, which at first glance are only applicable to xml and not xls files (when I try to define a variable as a dataset in my vb.net code, I face a message saying: Missing reference required to assembly System.Xml...).
How I would create this spreadsheet using a vb.net code in SSIS packages? Please, help...
Thank you.

Hi *, is there a way to connect Excel to SQL Server so that Excel serves as a frontend to SQL Server? I heard rumors that this is possible with the 2007 release.
I'm looking for a product that helps me storing massive data outside an Excel file. Right now, I'm using Palo (open source multidimensional database).

Hello, I have a situation in which I need to use a foreach iterator that will perform a transformation on each excel file in a directory. The file names will change, but the structure will stay the same.
I was able to get this working by assigning the file path for each iteration to a variable, and then using that variable to set the excelfilepath in the Excel connection manager. However, for this to work I have to assign the variable to a default file.
Because of this, when I try to deploy the package I need to also add a configuration property for the variable, otherwise the first run will fail. The dummy file doesn't even really need to exist - I just have to put in a valid path, and then use any name that has an .xls extension. After that it runs fine regardless of what is in the directory.
This seems odd that I would need to do this - am I missing something? Apart from creating the Excel Connection Manager programatically (which I'm guessing might solve this), is there a way to avoid having to specify this dummy file?
Thanks

Hi SSIsians,
I have a package with Excel Destination with dynamic connection.
I did ExcelFilePath = [@user::VarSourceFolder]+[@user::VarSourceFileName]
then i changed the Delayvalidation = True.
When i try to run the package in BIDS it gives the error.
ERROR:
[Excel Source [30501]] Error: An OLE DB error has occurred. Error code: 0x80040E37.
[Excel Source [30501]] Error: Opening a rowset for "DailySheet" failed. Check that the object exists in the database.
It saying there is no sheet in the name of "DailySheet" but when i removed the expression in connection manager property it is working fine.
Please let me know what is the problem OR how to configure the dynamic connection in ExcelSource.
Thanks

Is it possible to create a temp table using exec. e.g
exec('create table #temp1 (xyz int, abc int)')
when I run the above statement, I dont get an error but nothing happens.
The reason I need to create it dynamically is that in my stored proc, I am passed a number. This number determines how many columns my temp table should have.
thanks

The following dynamic SQL script works for creating a table on the fly but if I change the select @tmpTblNm = 'tmpABC' to select @tmpTblNm = '#tmpABC'
it will not create the temp table. Can anyone help on creating a temp table dynamiclly?
declare @tmpTblNm varchar(40),
@str varchar(1000)
select @tmpTblNm = 'tmpABC'
select @str = ''
-- Create a temp table to hold the current page of data
-- Add an ID column to track the current row
select @str = 'Create Table '+ @tmpTblNm +
' ( row_id int IDENTITY PRIMARY KEY,

Hi,
I'm trying to import a csv file directly to my database every month. The contents of the file stays the same, however the format of the columns may vary. For example, 1 month I can have the following:
Time, Probe1, Probe2, Probe3, Probe4
Whereas the next month I can have something like this
Time, Probe2, Probe3, Probe1, Probe4
The "Time" column will always be on the left side, but the probes may vary in their placement.
I'm importing this csv to a temp table, where I then run a query to select any new data and enter that in my main tables. The problem is that when i import the csv, if the placement of the columns has changed, the data gets entered in the wrong locations.
Is there any way to create this temp table dynamically, based on what the header columns of the csv file are?
Any help appreciated!

Hi,
I have a project which is need dynamically t-sql clause...I've created interface for the create dynamic t-sql clause.
But the clause should get data from relational database. It needs inner join...so it's very hard to do it..
for example
lkpProduct
id product
1 Mouse
2 Keyboard
3 Modem
4 Monitor
main
id productid
1 4
2 1
3 2
4 3
5 4
You can get this table with 2 ways like this..
1. Select main.id, lkpProduct.product from main,lkpProduct where main.productid = lkpProduct.id
2. Select id, case productid when 1 then 'Mouse'.....end as product from main
mytable
id product
1 Monitor
2 Mouse
3 Keyboard
4 Modem
5 Monitor
My question is; how can i use CASE function dynamically ?? Mouse should get from lkpProduct....I do not want to write long table manually..
I hope it is clear for you..
