How To Specify Datatypes For Excel Columns?
Oct 11, 2006
So I have Excel Source in my dataflow - so I do a simple transform and try to save it to db and guess what - a freaking error message: Columns blahblah and BlahBlah cannot convert between unicode and non-unicode datatype. I cant figure this MS stuff out - why the heck is this data from excel unicode to begin with & I just dont feel it is right to always use the derived columns to convert datatypes when dealing with Excel data. Am I missing something again or is it another one of those MS gotchas?

I am trying to figure out how the Excel source component determines that a column in an Excel sheet is a datatype of float when there is no data in the sheet, only column headers.
I created a package and dragged an 'Execute Sql task' from the toolbox onto the control flow. I made the ConnectionType = 'Excel' and then Connection = 'New Connection' and used the dialog to specify a path and also checked the 'First row has column names' box. In the SqlStatement I put the following:
create table `Tab1`
(Id integer
,Description nvarchar(255)
)
Then I ran the package and it sucessfully created the workbook and the 'Tab1' worksheet.
Now I create a new package and I drag a 'Data Flow Task' from the toolbox onto the control flow. I edit the Data flow task and drag an 'Excel Source' onto the 'Data Flow'. I edit the 'Excel Source' component and click the 'New Connection' button and I browse to the workbook file I created above. In the 'Name of excel sheet' drop down, I select 'Tab1' and click OK. Now when I open the Advanced Editor for the 'Excel Source' and then click on the 'Input and Output Properties' tab, I expand the 'Excel Source Output' node. Then I select the 'External columns' and I select the 'Id' column and I see that the datatype is 'double-precision float'.
I am wondering how SSIS knows that it is a float even though there is as yet no data in the table only the column headers. There does not appear to be any numeric formatting either. Interestingly, if I close the Advanced Editor and then open the workbook and I merely click the 'Save' button without having made any change, then if I again look in the Advanced Editor, it now prompts me that the datatype of the 'Id' column has changed. It seems that the datatype has changed to Unicode string. Can anyone explain why this happens? Why did simply clicking the 'Save' button in the excel sheet cause the datatype to change from float to string. What actually changed in the worksheet? I am using Excel 2003, SQL Server 2005 SP2 and Visual Studio 2003 Pro SP1. Thanks for any insight into this.

Hello.
I'm importing some data from an excel file to sql server 2005.
I created an Excel Data Source inside my Data Flow Task but it is assuming that the source columns DataType is double-precision float [DT_R8]. It isn't, even though some rows may containg numeric string in the column's cell.
If I go to the Data Sources advanded editor, and modify the data type property of the column, SSIS complains the the error output and the source output are not of the same DataType. If I try to change the error output's data type in the advanced editor I get this error: "Property Value". The deailed error states:
Error at MOVIM 04 [MOVIM 04 [1]]: The data type for "output "Excel Source Error Output" (10)" cannot be modified in the error "output column "Agente Protector" (7662)".
Error at MOVIM 04 [MOVIM 04 [1]]: Failed to set property "DataType" on "output column "Agente Protector" (7662)".
If i let SSIS correct the error by itself, it changed the dource column back to double-precision float [DT_R8].
Is there any way to get arround this?
Thanks in advance,
Hugo Oliveira

Is it possible to get data-type,default-value, etc. (basically schema information) of columns in a particular query.This is something similar to what we get when we execute the following
SELECT *
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'Employees'
But instead of TABLE_NAME i would like to give a query like
SELECT [EmployeeID],[LastName],[FirstName] from [dbo].[Employees] order by [EmployeeID].

I am using a Excel Source to get the data from an excel file to sql server 2005 table. A couple columns are coming in a double precision float, but some values have characters in them, but those values are coming out as null, even though I changed the datatype from float to unicode string. Any inputs on resolving this will be much appreciated.
Thanks,
Manisha

I have two spreadsheets in excell. There are 3000 numbers on one sheet, and there are 900 numbers on the other sheet. I want to know which numbers overlap and either somehow flag the overlaping numbers on both sheets or create a third sheet that just contains the numbers that exist in both. Is there some straightforward set of function comands in excel to do this?
Thanks for any help.

Hi guys,
i have a client who is dissatisfied with the merged columns and rows produced when SSRS renders to Excel, it prevents them from easily copying and pasting data into another workbook.
Is there going to be any work done in this area of the product in the near future? My understanding is that this 'issue' has been around for quite some time, and shortly after the SSRS2005 RTM release the team were going to look at tidying up the Excel rendering. Can anyone from MS make an official comment on this?
Thanks,
sluggy

Hi:
I use a SSIS package to loop thro a folder and load data from multiple excel files to a SQL2005 table. Works fine except when an excel has a missing col.
Col names in xls are always a subset of col names in the table. The missing cols are random, else I would just have made another package:-)
Once a missing column is found, I get runtime and design time errors, and metadata problems. How can a get SSIS to ignore missing columns?
TIA

I created an Excel Source and used a query to get the data,i.e
SELECT F1,F2,F3,F4,F5,F6,F7 FROM [Fut Days$A20:G1480]
The query works fine, the preview returns the rows, but SSIS will not generate output Columns nor will it let me manually add them? Am I missing something?

Is there a way to control the way Reporting Services exports the report to Excel? The actual report being exported is filling all the columns and lines with blank into the sheet. The report has only 600 lines and 5 columns and the final Excel file is about 3 MB in size because is filling the 65,XXX lines allowed by Excel.

I am trying to update a SQL table using an excel file which has 2 columns FMStyle and FMHSNum.
FMStyle is my link to the SQL table.
Here is what I have for code....
--------------------------------------------------
Update DataTEST.dbo.zzxstylr
SET hs_num = (select FMHSNum FROM OPENROWSET('Microsoft.ACE.OLEDB.12.0', 'Excel 12.0;Database=c: empStyleHSCodesLoad.xls;HDR=YES ', [Sheet1$]))
Where FMStyle = zzxstylr.style
--------------------------------------------------
Everything seems to be ok except for the "Where FMStyle" is giving me a message Invalid Column name on FMStyle. Do I need to qualify FMStyle and if so how.

Hi
I have an excel source which is a 41 column sheet. The excel filepath is stored in a table and captured into a variable. The excel source import is contained within a foreach loop and will loop through each file and continue until all the excel files are processed. It works fine until it gets to the last file. The import then fails with the following error:
The column "F42" needs to be added to the external metadata column collection.
The column "F43" needs to be added to the external metadata column collection.
The column "F44" needs to be added to the external metadata column collection.
The column "F45" needs to be added to the external metadata column collection.
The column "F46" needs to be added to the external metadata column collection.
The column "F47" needs to be added to the external metadata column collection.
Now when i open the excel sheet and hit CTRL+END the cursor goes to a column 6 to the right of the last column with data in it, effectively column 47 where column 41 is the end of my data.
I guess that the jet engine is trying to import these additional columns but because i am not expecting them there is no destination set up for them in the OLEDB destination and susequently the metadata needs to be added. I do not want to do this as these are excel files originating from the client and i cannot control how many additional columns they are going to "add".
Does anyone have any ideas as to how i can solve this? Is there a way of identifying the last column with data and only importing those columns?
Thanks in advance for any help or experience of this issue

Hi,
I have a package that uses an Excel file source. There appears to be no place to modify the column data types as you can with a flat file manager. As such, the source columns do not match the columns in the database.
I believe I must be overlooking something here.
Can someone please tell me how I can modify the Excel column datatypes?
Thanks

I have one issue left to solve before releasing my drilldown report to production. The report displays fine in report manager; however, when it is exported to excel, the color (Coral) in the last column on the right is bleeding into the next three columns in excel. I have looked at properties, sizing and searched the archives. Anyone have an idea how I can fix this to render properly?

Can you separate a domain attribute into two columns in the Excel Add-In?
We are using the Excel Add-In as the UI for business users and they want to see one of the domain attributes as 2 different columns.
The attribute is Store, currently it is displayed like this:
"123 {STORENAME }".
They want it displayed in two columns in the Excel document for easier filtering/sorting: Store Number and Store Name.
Is this possible? If one column is changed the other would change right along with it.

I have a data table which has list of bills with date and outstanding total.
If the bills dates between 0 and 30 I like to insert the Outstanding total into Colum K ,
If the bills dates between 31 and 60 I like to insert the Outstanding total into Colum L ,
If the bills dates between 61 and 90 I like to insert the Outstanding total into Colum M and so on ..
I tried below formula but it is not working
CASE DATEDIFF(day, Ac_Billbook.BillDate, getdate()) Between 0 and 30 THEN Insert into (Ac_Billbook.OutstandingTotal) Value ('K')
CASE DATEDIFF(day, Ac_Billbook.BillDate, getdate()) Between 31 and 60 THEN Insert into (Ac_Billbook.OutstandingTotal) Value ('L')

We have a requirement to produce adhoc Excel reports with a standardized header page with a disclaimer attached. We want to be able to feed in a SQL Statement, or a table with the resultset from a SQL Statement and have SSIS populate an existing blank Excel workbook, which the disclaimer attached. The use of xp_cmdshell is not an option.I've spent a lot of time looking for solutions on the web and it seems though its not possible - although many articles are 3-5 years old. Before I throw in the towel, I just wanted to get feedback from this group if it still is not possible in the latest versions of SQLServer and SSIS, or to ask if there are any other 3rd party solutions that can do this today.

Nice topic, Hidden columns!!
I read several threads about this topic.
This is what I understood:
when you hide a COLUMN based on an Expression when you render the report all the hidden columns takes space at the end of the report because the body doesn't rezise.
It seems that there is no workaround, this is how RS works (any correction is appreciated) and I can leave with it because I don't have so much hidden columns.
My problem is that the background color of the columns of the table is RED and when I export the report to PDF, at the end of the table with the visible columns I have some columns red..
If these extra columns would be white it could be acceptable, but these red columns are really annoyng!
Someone can advice me how to solve this issue?
Thank you

(Applies to SQLServer 2005 SP1)
We have found that using the SSIS "Import and Export Wizard" using the "Microsoft Excel" data source that there appears to be a maximum column length of 255 characters for any row.
Even when defining the destination table columns as nvarchar(4000), the wizard fails with the errors shown below.
We have found no workaround except manually changing the imput data. There doesn't appear to be any "Advanced" options for the Excel importer as there are for the flat-text importer. So, no question here, just posting the bug so that *next* time someone searches the web for an answer, this post comes up
MessagesError 0xc020901c: Data Flow Task: There was an error with output column "English String" (18) on output "Excel Source Output" (9). The column status returned was: "Text was truncated or one or more characters had no match in the target code page.". (SQL Server Import and Export Wizard) Error 0xc020902a: Data Flow Task: The "output column "English String" (18)" failed because truncation occurred, and the truncation row disposition on "output column "English String" (18)" specifies failure on truncation. A truncation error occurred on the specified object of the specified component. (SQL Server Import and Export Wizard) Error 0xc0047038: Data Flow Task: The PrimeOutput method on component "Source - Sheet1$" (1) returned error code 0xC020902A. The component returned a failure code when the pipeline engine called PrimeOutput(). The meaning of the failure code is defined by the component, but the error is fatal and the pipeline stopped executing. (SQL Server Import and Export Wizard) Error 0xc0047021: Data Flow Task: Thread "SourceThread0" has exited with error code 0xC0047038.

(SQL Server Import and Export Wizard) Error 0xc0047021: Data Flow Task: Thread "WorkThread0" has exited with error code 0xC0047039. (SQL Server Import and Export Wizard)
edit: After searching further this is documented under "Excel Source"
in BOL which provides a registry-based workaround. I guess the issue
is that the wizard considers truncation to be a 'fail' case and
there's no easy way to override this behaviour, specify the column
types nor determine which line is in error)
Truncated text. When the driver determines that an Excel column contains
text data, the driver selects the data type (string or memo) based on the
longest value that it samples. If the driver does not discover any values longer
than 255 characters in the rows that it samples, it treats the column as a
255-character string column instead of a memo column. Therefore, values longer
than 255 characters may be truncated. To import data from a memo column without
truncation, you must make sure that the memo column in at least one of the
sampled rows contains a value longer than 255 characters, or you must increase
the number of rows sampled by the driver to include such a row. You can increase
the number of rows sampled by increasing the value of TypeGuessRows under
the HKEY_LOCAL_MACHINESOFTWAREMicrosoftJet4.0EnginesExcel registry
key.

Hi all,
Currently, I am using the SSRS 2005 and try to toggle the report columns similar to Excel's column grouping function. Users can expand "+" / collapse "-" the columns in the render excel report. It works fine when I excute the tabular report in the web yet the toggle function is missing when I render the report to an Excel report. I am not sure the toggle function will only work for the row items or both as the excel report can keep the toggle function for the row items. Please help.

Hi,
I'm reading values from a named range within an Excel spreadsheet using the Excel ODBC driver. If I ask for all columns within a range, using e.g. select * from 'named range', does the driver ensure that the returned rowset has the same column and row ordering as in the spreadsheet? In other words, if a named range on a spreadsheet is the block of cells:
name age
richard 54
jemima 27
I want to make sure that my returned rowset is not going to be:
age name
jemima 27
richard 54
I know that proper databases do not guarantee the order of returned values (unless you specify it) but since Excel is a fixed view of data I was hoping that a returned rowset of values would retain their spreadsheet ordering.
Thanks,
aionaut

I have a task where I need to process roughly 60000 excel spreadsheets and bring them into a SQL Server 2014 database. All excel files have the same format and same number of identical columns. I have set up an SSIS package that is using Foreach Loop Container to look into a folder and process these files one at a time and load them to a table. The mappings are straight-forward, no problems there.
I am attaching a sample spreadsheet with two tabs - current structure and desired structure.
Basically what I need to do is to repeat the first 7 columns based on the number of lines in a transaction.
The number of lines is variable per patient.
