I'm trying to load data from my database into an excel file of a standard template. The package is ready and it's running, throwing a couple of validation warnings stating that truncation may occur because my template has fields of a slightly smaller size than the DB columns i've matched them to.
However, no data is getting populated to my excel sheet.
No errors are reported, and when I click preview for my OLE DB source, it's showing me rows of results. None of these are getting populated into my excel sheet though.
You should first make sure that you have data coming through the pipeline. In the arrow connecting your Source task to Destination task (I'm assuming you don't have any steps between), double click and you'll open the Data Flow Path Editor. Click on Data Viewer, then Add and click OK. That will allow you to see what is moving through the pipeline.
Something to consider with Excel is that is prefers Unicode data types to Non-Unicode. Chances are you have a database collation that is Non-Unicode, so you might have to convert the values in a Data Conversion task.
ALSO, you may need to force the package to execute in 32bit runtime. The VS application develops in a 32bit environment, so the drivers you have visibility to are 32bit. If there is no 64bit equivalent, it will break when you try and run the package. Right click on your project and click Properties and under the Debug menu you'll need to change the setting Run64BitRuntime to FALSE.
you dont provide much informatiom. Add a Data View between your source and your excel destination to see if data is passing through. Do do it, just double click the data flow path, select data view and then add a grid.
Run your app. If you see data, provide more details so we can help you
Couple of questions that may lead to an answer:
Have you checked that data is actually passed through the SSIS package at run time?
Have you double checked your mapping?
Try converting within the package so you don't have the truncation issue
If you add some more details about what you're running, I may be able do give a better answer.
EDIT: Considering what you wrote in your comment, I'd defiantly try the third option. Let us know if this doesn't solve the problem.
Just as an assist for anyone else running into this - I had a similar issue and beat my head against the wall for a long time before I found out what was going on. My export WAS writing data to the file, but because I was using a template file as the destination, and that template file had previous data that had been deleted, the process was appending the data BELOW the previously used rows. So, I was writing out three lines of data, for example, but the data did not start until row 344!!!
The solution was to select the entire spreadsheet in my template file, and delete every bit of it so that I had a completely clean sheet to begin with. I then added my header lines to the clean sheet and saved it. Then I ran the data flow task and...ta-daa!!! Perfect export!
Hopefully this will help some poor soul who runs into this same issue in the future!

When trying to add external data in excel, the data connection wizard does not load properly for some reason.
I select Data,> From Other sources, >From Data Connection Wizard>My Data source>table i want...
Then I have no options to set parameters, can only click "Finish" without any query set up.
Just Defaults to "Select * FROM XXXXX"..
Anyone have any ideas as to why this would be the case?
I have done this exact same process before, on multiple occasions, with to issue.
Something has changed to make this process not work properly.
There are big changes going on in the excel data input environment recently and all the process are being remodeled and reworked. I checked my excel 16 and it doesn't even list the option you mention (Data connection Wizard) anymore. I feel a strong push towards Data model which may not suit me or other, but all other connection methods are gradually ceasing to work.
I would guess you perhaps do not have a latest Excel version and so it just happens.
I have been working on building a new database. I began by building the structure within the database it is replacing and populating this as I created each set of tables. Once I had made additions I would drop what had been created and execute the code to build the structure again and a separate file to insert the data. I repeated this until the structure and content was complete to ensure each stage was as I intended.
The insert file is approximately 30mb with 500,000 lines of code (I appreciate this is not the best way to do this but for various reasons I cannot use alternative options). The final insert completed and took approximately 30 minutes.
A new database was created for me, the structure executed successfully but the data would not insert. I received the first error message shown below. I have looked into this and it appears I need to use the sqlcmd utility to get around this, although I find it odd as it worked in the other database which is on the same sever and has the same autogrow settings.
However, when I attempted to save the file after this error I received the second error message seen below. When I selected OK it took me to my file directory as it would if I selected Save As, I tried saving in a variety of places but received the same error.
I attempted to copy the code into notepad to save my changes but the code would not copy to the clipboard. I accepted I would lose my changes and rebooted my system. If I reopen this file and attempt to save it I receive the second error message again.
Does anyone have an explanation for this behaviour?
Hm. This looks more like an issue with SSMS and not the SQL Server DB/engine.
If you've been doing few times, possibly Management Studio ran out of RAM?
Have you tried breaking INSERT into batches/smaller files?
I struggled with this issue for too long before finally tracking down how to avoid/fix it. It seems like something that should be on StackOverflow for the benefit of others.
I had an SSRS report where the query worked fine and displayed the string results I expected. However, when I tried to add that field to the report, it kept showing "ERROR#". I was eventually able to find a little bit more info:
The Value expression used in [textbox] returned a data type that is
not valid.
But, I knew my data was valid.
Found the answer here.
Basically, it's a problem with caching and you need to delete the ".data" file that is created in the same directory as your report. Some also suggested copying the query/report to a new report, but that appears to be the hard way to achieve the same thing. I deleted the .data file for the report I was having trouble with and it immediately started working as-expected.
After you preview the report, click the refresh button on the report and it will pull the data again creating an updated rdl.data file.
Another solution to this issue is to click Refresh Fields in the Dataset Properties menu.
This will update the list of fields, and force SSRS to get new data, rather than relying on a cached version.
I have a data set with multiple tables. In one of these tables I have included some scalar queries that take various fields of the table and spit out a single result (for instance average of fields X, Y, and Z), etc. Up to now, I have had great success with this, but now I am getting a very odd issue cropping up.
When I try to add a new scalar query, I am putting my SQL in the screen and naming my query, just like I normally do. However, whenever I do this now, it creates a duplicate of the DataSet.Designer file (now DataSet*1*.Designer), and I start to get compiler errors since all functions within the partial classes are duplicated. I am only able to back out of this by deleting the new designer file, in which case my new SQL query is now unavailable (but I still see it in the original designer view).
I am not sure why this is happening. Can anyone shed any light on why the IDE is creating a new DataSet.Designer file instead of modifying the original?
Discovered the answer. It looks like this may happen if some process is using the original designer file, and the IDE tries to generate a new one. Unfortunately, it doesn't reconcile that the old one is still there. This will correct the issue.
Delete the newest (offending) designer file from your project
Close the project.
Open the vbproj file using a text editor.
Search for the following..
<LastGenOutput>myDataSet1.Designer.cs<LastGenOutput>
Take the 1 off of the dataset name
save the file and reopen your project.
Text was truncated or one or more characters had no match in the target code page.
how to avoid this error practically while import data from excel
In general, this could be caused by the fact that you have data that is too long in your source file compared to the field it is going into, the data is in different formats (source to destination), or something else in general like this. However, since you mentioned that it is coming from Excel, you might want to try this solution too, which works only for Excel:
Set your package to run in 32-bit mode. Click on Project on the top menu and select Data Imports Properties. Click on Configuration Properties -> Debugging and set the Run64BitRuntime to false.
This solution sometimes works for Excel projects, but it is an outside shot. If it doesn't work, try look at the data formats and fields in the source (and what they are being imported as).
