Write To Excel Destination Component With Specified Range

Apr 24, 2008

I have an SSIS package that produces an Excel output file say File1
The Excel output file is created from a previous script task by copying a standard excel template to File1
after the copy, File1 has the disclaimer, legend etc... and a header row at row 10.
So data rows should only start at row 11.

I was googling and found that people who read Excel file using an Excel source component have been successful reading
from a range by the use of the OPENROWSET property. It is said to set this property to Sheet1$A5-B999
to start reading from row 5.

I tried to set the OPENROWSET property to be Sheet1$A11-B999 but am getting an error "Check that object exists"
(Sheet1 does exist) So I guess it is the range that has an improper syntax or something else is wrong.

Please advise. Thanks

How To Set Sheetname On An Excel Destination Component ?

Sep 21, 2007

Hello, I am trying to create a simple package programmatically. I am following the examples in the BOL, and from some advice here. I am getting stuck at creating an Excel Destination and setting its sheetname. Everything works fine, including setting the output Excel filename. I get a runtime exception when I try to set the sheetname via SetComponentProperty. Is there another way, or am I doing something wrong? Thanks for any info you may have.

' Create and configure an OLE DB destination.

Dim conDest As ConnectionManager = package.Connections.Add("Excel")

conDest.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & _

Excel Destination: Write Over Existing Data

Jan 26, 2007

I have a daily package that extracts some data and writes it into an excel file. I want to write over the existing data, but the excel destination only appends the next free location in the worksheet. I tried using a SQL task to grab the file, set all the cells = NULL and then run the rest of the package, thinking it would see the null cells as empty and write in them, but somehow it knows where the previous data ended and keeps appending further down in the workbook.

Does anyone know of a workaround so I do not have to delete and re-create the file everytime?

TIA,
Sabrina

Excel Destination Data Flow Component Shows No Sheet Name Or Output Column Names For Mappings

Mar 8, 2008



I have a data flow that consists of

OLE DB source which calls a stored proc that returns a result set

data conversion

Excel destination
I am in design mode in Business Intelligence studio. My excel destination (with an Excel Connection) shows no sheet name though I have an execute SQL task before the data flow to create the excel table called SHEET1. Needless to say, there are no output columns visible to do any mappings. I did go to the ExcelConnection to set the OpenRowset Property to SHEET1 but it seems to have no effect.

I can do the export in SQL Server Management studio and that works fine, but it is basic and does not meet my requirements. I have to customize the package to allow dynamic Excel filenames based on account names and have to split my result set into multiple excel sheets because excel 2003 has a max of 65536 rows per sheet. Also when I use the export wizard, I have the source as a table and eventually the source has to be a stored proc with input parms.

What am I missing or doing wrong? Thanks in advance

OLE DB Destination Component

Feb 6, 2007

when loading the transformed data into OLE DB destination, there is no options to truncate destination table first. Have to insert a middle step to run script to truncate the destination table first.

I'm very confused. We even has the options of keeping or deleting the data in destination table in SQL2000 DTS package. Why we don't have this option in SQL2005??

Excel Destination Appends The Excel File Everytime A Package Is Executed

Dec 18, 2006

i have an SSIS package that exports to an excel file. This works fine. the problem is that it appends the data instead of overwriting the file. Is there any way to overwrite the file like you can with a flat file? I have to email the file everyweek and don't want to have to clear it out manually. Any help would be appreciated

Help With Invalid Destination Component.

I have the source component set up fine, and the destination component seems good, but when the package is run, it gets the error message: "Excel destination failed validation and returned validation status "VS_NEEDSNEWMETADATA" ".

Problem With Retreving A Excel Data Through Excel Source Component.

Sep 18, 2007



Hello,

I have a problem with retreving a excel data through excel source component.

I have source component as Excel Source which will connect to my .xls sheet.
To retrieve the values from the sheet i am using a query as,
"SELECT F14,F3 FROM [Charac Defn & Assgnment$]"

The column F14 is not formatted so that the format of the cell is "General" I have a different type of values in the F14 column such as "PE","PES",15,20,20.00,8888.9999 etc..
While i click on preview button of Excel source it shows only the text values and not the int or decimal values, its returning NULL for those cells. I tried to use convert function, its throwing an error as

TITLE: Microsoft Visual Studio
------------------------------
There was an error displaying the preview.
------------------------------
ADDITIONAL INFORMATION:
Undefined function 'Convert' in expression. (Microsoft JET Database Engine)


Is there any other function to change the format of the cell or i need to some thing else
Please help me how to solve this issue.

How To Write Date Range On Case Statement

Oct 30, 2012

I have a case statement as follows which I am using in the where clause to get today's data

(Case when (A.ID is null or B.ID = '' or C.ID= ' ') Then convert(varchar,(Case when A.Time is null then B.Time else A.Time end),103)

else convert(varchar,(Case when A.Time is null then ''" else B.Time end),103) end)

=convert(varchar,getDATE(),103)

However I want to know whether I can use a date range on a case statement

I.e. I want to be able to use BETWEEN statement to get a date range

BETWEEN convert(varchar,getDATE(),103) AND convert(varchar,getDATE()-1,103)

How do I achieve this on a CASE WHEN statement?

Create A Table And Then Using It As OLE DB Destination Component

Apr 12, 2007

I want to do the following in a package:



Create a table at the beginning of a package (using a ExecuteSQLTask component) and then use the created table as a OLE DB destination component, later on the package.



Is this possible in SSIS?



The problem I run into is that I have to point the OLE DB destination component to a table and set up mappings, however as the table does not exist until the package is running, it does not seem to be possible.



I've looked at:

http://blogs.conchango.com/jamiethomson/archive/2006/11/19/SSIS_3A00_-Using-temporary-tables.aspx



Which is slightly similar to what I want, but the table I create would not be a temp tables, and I need to set up mappings and I don't see how this is possible.



Thanks

How Do I Programatically Fail My Custom Destination Component?

Nov 8, 2006

I am writing a custom dataflow destination that writes data to a named pipe server running in an external process. At runtime, in PreExecute, I check to see if the pipe exists. If it does not exist I want to be able to fail the component and gracefully complete execution of my package.

Question is, how do I do this? If I make a call to ComponentMetaData.FireError() that will only create an OnError event and not actually stop the execution. So, how to I halt the execution of my component and return the error message?

Thanks,

The Data Flow's Default Destination Component

Dec 10, 2007

Is there a default destination component used when a new data flow is created? The reason I ask is simply curiosity. I have an xml file with 2 pieces of data: item A and item B. A should simply get copied out of the file. B should undergo a quick transform. I set up an XML source such that two columns are mapped correctly to the XML source data of A and B. I set up my data transform task as well. So, if I leave those two components on the .dtsx page with no other components, then will there be a default data flow destination already created? ...OR, do you always have to have a destination component?

Thanks for the input. I am just curious.

How Do I Order Columns In My Custom Destination Component?

Nov 17, 2006

Here is the situation. I have created a package that takes 50 columns from a comma delimited flat file. I then validate and clean the data. Next I add two columns that were not in the original source file. These two columns need to be in the 5th and 9th column position when the file is then re-written to a text file. How do i get those two columns to write out in the desired order? Any ideas?

Selecting Connection In Custom Destination Component UI

Feb 24, 2006

Hi there,

I am writing a Custom Destination component with a custom UI. The UI contains a combo box which contains the connection names of type €œFLATFILE€?. I also have provided a button which would create a new connection of type €œFLATFILE€? by making a call to CreateConnection method of IDtsConnectionService.
The combo box gets properly updated showing the connections of type €œFLATFILE€? but on clicking on the new Connection button the application hangs up.
Am I missing something or is there some other way to do it?

The function are the events handlers which are called by the UI.





void form_GetConnections(object sender, AvailableColumnsArgs args)
{
Debug.Assert(this.ServiceProvider != null, "Service Provider not valid.");

this.ClearErrors();

try
{
IDtsConnectionService connectionService = (IDtsConnectionService)this.ServiceProvider.GetService(typeof(IDtsConnectionService));

if (connectionService != null)
{
ArrayList temp_Connections =
connectionService.GetConnectionsOfType("FLATFILE");

args.AvailableColumns = new AvailableColumnElement[temp_Connections.Count];
for (int i = 0; i < temp_Connections.Count; i++)
{
ConnectionManager runtimeConnection = (ConnectionManager)temp_Connections;
args.AvailableColumns.AvailableColumn = new DataFlowElement(runtimeConnection.Name, runtimeConnection);
}

}
}
catch (Exception ex)
{
this.ReportErrors(ex);
}
}

void form_GetNewConnection(object sender, AvailableColumnsArgs args)
{
Debug.Assert(this.ServiceProvider != null, "Service Provider not valid.");

this.ClearErrors();

try
{
IDtsConnectionService connectionService = (IDtsConnectionService)this.ServiceProvider.GetService(typeof(IDtsConnectionService));

if (connectionService != null)
{
connectionService.CreateConnection("FLATFILE");

ArrayList temp_Connections =
connectionService.GetConnectionsOfType("FLATFILE");

args.AvailableColumns = new AvailableColumnElement[temp_Connections.Count];
for (int i = 0; i < temp_Connections.Count; i++)
{
ConnectionManager runtimeConnection = (ConnectionManager)temp_Connections;
args.AvailableColumns.AvailableColumn = new DataFlowElement(runtimeConnection.Name, runtimeConnection);
}

}
}
catch (Exception ex)
{
this.ReportErrors(ex);
}
}

Has anyone else run into this?

I am running
SQL 2005 9.0.1399 and VS 2005 8.0.50727.42 (RTM.50727.4200) on Windows Server 2003 Enterprise Edition SP1.
Any suggestions would be welcome.

The code sample is an extension to the RemoveDuplicates sample (Dec 2005) which comes along with the SQL Server.

Performance Issue With Custom Data Destination Component

Feb 12, 2008

Hi,
All the examples I've seen for creating custom data destinations (scripts or components) show that in the ProcessInput method you need to iterate through each record and execute a commit for each row. Here's a sample from http://forums.microsoft.com/msdn/showpost.aspx?siteid=1&postid=70469



Public Overrides Sub MyAddressInput_ProcessInputRow(ByVal Row As MyAddressInputBuffer)
With sqlCmd
.Parameters("@addressid").Value = Row.AddressID
.Parameters("@city").Value = Row.City
.ExecuteNonQuery()
End With
End Sub

This works for me but is extremely slow when processing lots of rows. Has anyone come across a better/faster example for committing rows to a database when creating a custom data destination component? I was thinking about using the ADO.NET batch update. Any thoughts on this or other approaches?

Thanks,

Mike Fulkerson

Custom Destination Component Logging - Wrote 0 Rows

Mar 17, 2006

I wrote a custom destination component. Everything works fine, except there is a logging message that is displayed that I cannot get rid of or correct. Here is the end of the output of a package containing my component:

Information: 0x40043009 at Data Flow Task, DTS.Pipeline: Cleanup phase is beginning.
Information: 0x0 at Data Flow Task, MyDestination: Inserted 40315 rows into C: empfile.txt
Information: 0x4004300B at Data Flow Task, DTS.Pipeline: "component "MyDestination" (9)" wrote 0 rows.
SSIS package "Package.dtsx" finished: Success.

I inserted a custom information message that contains the correct number of rows written by the component. I would like to either get rid of the last message "... wrote 0 rows", or figure out what to set to put the correct number of rows into that message.

This message seems to happen in the Cleanup phase. It appears whether I override the Cleanup method of the Pipeline component and do nothing, or not. Any ideas?

public override void Cleanup()

{

ComponentMetaData.FireInformation(0, ComponentMetaData.Name,

"Inserted " + m_rowCount.ToString() + " rows into " + m_fileName,

"", 0, ref m_cancel);

base.Cleanup(); // or not

Write Value From Script Component To Variable (Datatype Object)

May 8, 2008

Hi,

I have a script component that contains a script similar to that shown below;


Public Sub Main()

Dim sqlConn As New SqlConnection("Server=myserver;Database=mydb;Trusted_Connection=True;")

Dim SQLStmt As String

SQLStmt = "select top 10 CountID from mytable"


Dim sqlComm As New SqlCommand(SQLStmt, sqlConn)


sqlConn.Open()



Dim r As SqlDataReader = sqlComm.ExecuteReader()
While r.Read()


Dim MyValue As Integer

If r("CountID") IsNot DBNull.Value Then

MyValue = CInt(r("CountID "))



' HERE I WANT TO WRITE MyValue TO A PACKAGE VARIABLE AS A ROW

End If


End While

r.Close()
sqlConn.Close()

Dts.TaskResult = Dts.Results.Success

End Sub


Once i have a value assigned to MyValue, I want to write this as a row to a variable (DATATYPE Object Value VALUE System.Object) in the package which will be an ADO Recordset Destination that i can then loop through later.

Many thanks for any help

Script Destination Component Code Sample Here That Creates A Csv Or Xml File

Jul 11, 2006

After much work and thanks to all of you who helped on this here is a code sample that can be adapted. From the dataflow task add an OLEDB source component, a row count component and finally a Script Destination Component.

On the Script Destination Component rename the Input node of the imports and outputs tree view to "ParsedInput"

The readonly User: variables that start with gs can be read in the PreExecute method

The readwrite User: variable giSuccessCount can only be used in the post execute task because it is populated by the Row Count Component which is the previous object in the Dataflow

The xml code is adapted from an idea in Donald Farmers book

enjoy

Using Script Destination Object To Create And Write To New Text File

Jul 31, 2007

Is there a better way to do this?

We've all seen this, where it uses an individual .write statement for each column.





Code Snippet

Public Overrides Sub AWCCogent_ProcessInputRow(ByVal Row As AWCCogentBuffer)


With textWriter

Dim item As Object

If Not Row.AddressID_IsNull Then
.Write(Row.AddressID)
End If
.Write(columnDelimiter)
If Not Row.City_IsNull Then
.Write(Row.City)
End If

.WriteLine()


End With

End Sub


But hard coding this seems not the smartest way. Especially since in my text file, there needs to be close to 100 columns. This could be a nightmare to update down the road. But I can't seem to find the object collection to loop through, like row.items which would seem to be logical.

There's gotta be a better way, right Microsoft?

Integration Services :: Don't Write Flat File Destination If Conditional Split Is Not True

May 8, 2015

I have a Problem with my destinations. I have a split condition with two ways the flow can use.

In this case: all and Date.

All and Date can be set by using a variable. Its working good.

When a user fills the variable with a date value (cast to string) the conditional split executes the correct flow with all the needed rows... The same time the all flow will be executed with 0 rows. In the end the destionation file for the all values will be overwritten with nothing. The same on the other hand when a user fills the variable with the all value, the date file is empty. What can i do to make sure that the files are not empty?

Export To Excel Range

Sep 12, 2007

I have an SSIS package that exports data to a named range in Excel, except that instead of putting the data in the named range, it adds the first row of data to the first row below the range. The spreadsheet is not protected. Why doesn't the data get put into the named range?

When I'm done testing the SSIS package, I want to protect the spreadsheet and enable edit for the named range so that data can be written using the SSIS package. Will enabling the named range be necessary?

Excel Range Insert

I have a Raw File Source in a Data Flow. The data is manipulated and then defined to insert into a named range within an Excel Worksheet. I have a task prior to the data flow that takes a template and copies it to another location. Within the Template I have defined several named ranges.

The Data Flow inserts the data in the line below the named range. For instance if I have a named range defined as B1:C1
the insert occurs on B2:C2

Does anyone know why this is happening or how I can get it to insert into the Range I have specified?

Thanks in advance!

Excel Destination Question

Mar 17, 2008



Hello-

I'm not able to find this information so I thought I would ask it here. I'm in the process of exporting some data from a OLE source to a excel spreadsheet. My only problem is that in the beginning of the spreadsheet there are some logos and other misc data. So I need to start my data dump on a few cells below all of this information . Is there a way to tell SSIS a certain cell to begin the data pull from a database table? I just want to start for example in cell "A50" instead of "A1". Is this possible ?

Excel Destination Options

Mar 17, 2008

I am looking to generate batch reports in an excel format when data becomes available. I want those files in a shared directory and I want the ability to send them out via email. Formatting is very important. I cannot use SSRS because the spreadsheets need additional formatting that SSRS does not provide (naming of tabs, numbers formatted as numbers without "the number in the cell is formatted as text..." comment, etc.). I also need to get this done quickly.

SoftArtisans OfficeWriter seemed to have a solution that generating excel sheets on the server using datatags in cells. I saw another post on xlsgen (http://www.excelgenerator.com/). I am a little suprised there is no Microsoft solution. Is there one outside of installing Excel on the server?
