Uploading Text And Numeric Data From An Excel File
Nov 3, 2006
Hi,
I have found a problem with my SSIS package. The package takes a Excel File using the Excel Source/Excel connection manager objects. There's a Data Conversion Object which sets all the fields to be DT_STR and then I import the data into a Holding table using a OLEDB Destination Object.
My Excel file contains a list of Code/Description pairs. The problem I have is that I can have data such as the following
CODE
A101
A102
A103
12
1.2i
What seems to be happening is that when the data is imported into the holding table and the first rows are Alphanumeric then the fields where there's a code such as 12 get converted to NULL for some reason. If all the codes are the same type (either Alphanumeric or numericit doesn't matter, as long as they are all the same) the import works perfectly well.
I need to be able to import all of these codes without SSIS converting some to NULL. Has anyone come across this problem before? If so, is there something I am doing wrong or a workaround?
Many thanks in advance
Rob

I have the Excel Connection Manager and Source to read the contents from an Excel file. For some reason couple of numeric fields from the Excel worksheet are brought over as nulls even though they have a value of 300 and 150. I am not sure why this is happening. I looked into the format of the fields and they are set to General in Excel, I tried setting them to numeric and that did not help.
All the other content from the excel file is coming thru except for the 2 numeric fields.
I tried to bring the contents from the excel source to a text file in csv format and for some reason the 2 numeric fields came out as blank.
Any inputs on getting this addressed will be much appreciated.
Thanks,
Manisha

Hi,
I needed to recreate/publish a DDL and data file(of a database) that was produced using Database Publishing Wizard. The size of the file is 4G. I receive the following error when I try to open it up in the new query window of sql server 2005 (sp2)for execution.
"The operation could not be completed. Not enough storage is available to complete this operation."
I know my server has 829G of free storage space available. i receive no errors when I open up a smaller file also created by database publishing wizard.
What possibly is causing this?
Thanks in advance

i've been reading some problems with excel source data being force as
numeric type when there are string/numeric type in the data, but adding
IMEX=1 to the extended properties will fix this problem...this is true
but not in my case...
say my excel file have about 40 rows..if row 1-39 in column A are all
NULL and row 40 has a string in it, the string in row 40 will not be
converted and the excel source is forcing this column A data type to be
numeric..having IMEX=1 in there does not work..however..if i add a
string anywhere in row 1-8 in column A, the the string in row 40 will
be converted because the external data type now is a string..
anyone know how to solve this problem?

I'm using SSIS 2005 Enterprise edition, I'm creating a package that reads an excel (xls) file using the "excel source" component, and it dumps the data into an OLEDB destination (a sql server). When I drag the excel source component and create the excel connection to my file the component automatically reads the columns and their datatypes.
The problem is that I have a column which has numeric data and the package uploads as NULL every number that starts with a zero. (note: in excel this column is formatted as "text", despite it has only numbers, because it's the only way excel maintains the left sided zeros).
So I checked the data types by right clicking the excel source component -> show advanced editor and my surprise is that this column's data type is detected as double-precision float, and it doesn't let me change it. URL... but it only works when the first row of data has a number beginning with zero on this column. How to get the data imported correctly?

Can somebody please tell me what I am doing wrong or need to do to resolve my issue. I having problems with one of the columns in an excel spreadsheet that I am trying to upload into the system. One of the columns contain values of both text and numbers such as 'ABC123', 'ABC124', '123456' etc. When I try uploading the sheet into SQL Server 2000 using DTS, the system removes all characters from the one column that I am having problems with. So entry 'ABC123' for example would be truncated to '123'. I tried formatting the column that I am having trouble with in excel to 'General' format as well as tried to transform the column to type varchar in SQL Server while using the DTS wizard but still had no luck. The problem is that SQL server thinks that the column is a float type column from the source and therefore truncates any characters.

Hi,
In my Excel file I have one column "Summary" which contains large amounts of data. In ExcelSource I changed the Output Column: Summary datatype to Unicode[DT_Ntext], but I am not able to chnage the External column datatype from [DT_WSTR] to [DT_NTEXT].
Initilly it is string so changed to unicode. Still I am getting this error:
"Failed to retrieve long data for column " Summary".
I tried the BlobTempStoragePath to other directory? Still not working.
How to solve this error?
Thanks in advance

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.

I have an excel file source, that has a column that is a date column, although the group puts in more that just a date sometimes: example (11/1/2007) or (Sold), the problem is I cant get SSIS to ever see anything but the date, for the cells that have Sold shows me null, or blank when doing a view. Any thoughts??? I am starting to hate excel more and more.

Guys
I'm getting the above when trying to populate a variable. The values in question are :
@N = 21
@SumXY = -1303765191530058.2251000000
@SumXSumY = -5338556963168643.7875000000
When I run, SELECT (@N * @SumXY) - (@SumXSumY * @SumXSumY) in QA I get the result OK which is -28500190448996439680147097583285.072256 ie 32 places to left of decimal and 6 to the right
When I try the following ie to populate a variable with that value I get the error -
SELECT R2Top = (@N * @SumXY) - (@SumXSumY * @SumXSumY)@R2Top is NUMERIC (38, 10)
Any ideas ??

Greetings,
Environment:
Server: SQL Server 2005 with service pack 1 running on Windows Server 2003
Clients: Internet Explorer 7, MS Office 2007
Setup:
Our companies reports are a mixture of Reporting Services Reports and Excel workbooks with pivot tables. We want both the reports and the pivot tables to be accessible from the same web page so users have a single entry point into all of the business intelligence tools. We have the Reporting Services Reports working just fine but there is an slight hiccup with the Excel documents. The Excel files upload just fine, but when clients try and download them they are always presented with the following Yes/No dialog:
"The file you are trying to open 'Resource.aspx' is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?"
Clicking Yes opens the file in excel but it is opened as Resource.aspx instead of the actual excel file.
Clicking No opens the file in excel as the actual excel file.
My questions are:
1. Why does the file upload correctly as an excel file type but download as an aspx?
2. Is there a way to let Reporting Services associate the .xlsx extension with Excel.
3. Is this even a Reporting Services problem? (I believe it is, because we also use SharePoint and excel files uploaded in sharepoint download correctly using IE7).
Any help or insight is appreciated.
Regards,
Jplocster

I have an .xlsx file where I need to import the data into a table. If there is not a way to do this, is there a way to import either a tab del file or different type of .csv file into the database?
Do not want to use the SSIS or import feature from SQL2008 as I tried to save the steps and running it wont work either.

hi all;
1. Excel file Source--> monthly Revenue details
2. Derived Colum Transoformations
3. Oledb Destination
its my flow in one of my packates (ETL job)
Excel file contains monthly revenue details, i wanna import the excel data to my database staging table, so i've created the package.
its working fine...
Problem
if we change the new data for the next month and running the package its not running;
the same file, same format, only we delete the contents, of the file except first row of the excel sheet,
and pasting the new data;
new data is coming from Oracle DataBase in the form of excel sheet ( manually they will copy the data and sending to us)
i open that package in design mode and while double clicking the excel file source it says <column name>'s Meta Data needs to be synchronized
Do you want to Fix this issue automatically with the available external column's meta data
Clearly noted that its a data type issue; i have changed the corresponding data types as it is in the previous Excel sheet which is equivalant to the Table its copying to.
now the package is running with validation warnings, External Column "Invoice Amount" needs to be updated...etc. some 2 or three warning messages i can able to see in the package Execution wizard,
ok, i'm ready to accept these warnings, and i want my package running from my server;( packages had been deployed in to the Centeralized server; every time if we want to run the package, we have the asp.net webpage, that is executing the package in an On_click event)
The package is not running from the server, its due to the meta data change in the Excel file( i guess)
please suggest me some guide lines to resolve this meta data issue, i want my excel sheet meta data should not change when we have new updates in it;
otherwise suggest me some solutions that i can validate the excel sheet before running the package and testing whether the data is in correct format or not? its a kind of Data Profiling activity;
i know its some what crazy, but i need to maintain the system with permanent solution, instead of facing this meta data mismatch issue!!!
some what lenthy explanation--> its needed for my dear powerful microsoft responders. i think i 've explained my problem clearly, if i don't let me know your queries, i'll try my level best.

I have yet to create a query string that works and it is beginning to drive me insane. I am trying to allow a user to upload a word document into my SQL 2000 database. However I always seem to get an error when it comes time to insert the file. The table has 5 fields memnumber, papertitle, and file type are all varchar. Length is an integer and actual_file is of type image. Here is my string
command = "INSERT INTO resumes (memnumber, papertitle, length, filetype, actual_file) VALUES ( '" & TextBox1.Text & "', '" & rightname & "', " & length & ", '" & type & "', " & filer & ")"
I can't tell you how many different versions of this string I have tried to run with none of them working, so the errors I have gotten have been varied. Most of them tell me either I can't use the & operator with file type image or that string or binary data would be truncated.

all these values are imported as nulls!!!
i am lost
i tried converting the format of these cells to numbers but then i loose the leading zeros

i then import them and convert them to strings in ssis and then ad dthe zeros.
now althouge this works, this isnt realy a solution.
i canot manualy correct each excel file each time i get a new copy

there must be a better way

I am having a problem importing an Excel spreadsheet. I have a column inan Excel sheet with alphanumeric text and some of the cells are numeric.Some of the cells contain numbers like 12345.6 and when DTS is doneimporting it into a field that is nvarchar the results are"12345.600000000001". I have tried:1. Changing the format of the Excel column to text2. Using the formula =text(a1,0) which only truncates the .63. Using the formula =t(a1) which will remove some numeric representations4. Exporting the sheet to CSV or TXT first which will not enclose the cellcontents with ""5. Beating the computer with a nine ironNone of these options work. Any idea anyone?Don VonderBurg

I'm importing a multi tab spreadsheet using Import wizard, which I understand to use the same internals as SSIS. The total number of columns in the spread sheet will be over 500. The import wizard defaults everything to varchar 255. I understand there is an XML file I can manipulate to change this and they are located
C:Program FilesMicrosoft SQL Server100DTSMappingFiles
Assuming one of these will control Excel defaults, which one is it? None of the names lend themselves to the Excel as a source. SqlClientToMSSql10?

Hello,
I have a table in SQL Server 2005 that has an NVarchar(50) column called AcctCode. I am trying to populate this column from an Excel source. I am doing this from the Import/Export Wizrds in Management Studio. When I attempt the import from the Excel file, all the the AcctCode data that is alpha numeric or just alpha will import, but the all numeric data comes in as NULL.
If I make AcctCode NOT NULL, I get an integrity contraint error from the wizard. The rest of the records import. I've tried to make the column in the Excel file type 'text', and have tried it with no formatting on this column.
Why won't the all numeric Acctcodes import?
Thank you for your help!

The ERP manufacturer used an image data type to store large text data fields. I am trying to move these data types from one database to another database using either Sql Queries or MS Access. I can cast them as an 8000 char varchar to read them directly but have no luck importing into these image data fields.
Access and Crystal are not able to read these fields directly.
Any suggestions? Most information about these fields has to do with loading files but I am just moving data.

Hey All,
I am developing a data acquistion system which monitors the amount of energy that a user consumes in different parts of a house and displays the information in real time on their computer screen. I am collecting the data through tranducers attached to the circuit breakers in the breaker box and sending the data to analog-to-digital converter channels in a MCU. I am retrieving the data from the serial port and storing it to a text file. Each line of data in the text file represents three fields which are separated by commas. I will be reading data from multiple data collection boxes so the first field is the unit number, the second fied represents the analog-to-digital converter channel number from each unit, and the third field is the data that is collected from the ATD channel. I am trying to use SSE to retrieve the data from the text file, and parse each line of data into individual columns in a databse. Then I want to be able to extract the data associated with a particular ATD channel number from the databse and display it in the appropriate text field on a windows form.
I've got the MCU programmed. I have no problem collecting the data from the serial port, and I can do the visual basic programming okay. I have absolutely no clue how to read the data into the database, continuosly read new values into the databse, and then access the stored data to update the text fields on the form. Please help if you can, I've been working on this specific problem for a couple of weeks and I'm not making any progress. Thanks.
