Excel Data Source SSIS AcquireConnection failed 0x80004005 unspecified error

Posted By:      Posted Date: September 02, 2010    Points: 0   Category :Sql Server
Nuances of using Excel data sources with SSIS Your Development Machine Setup Needs Jet Drivers, available along with the default Office install so if you have Excel working fine locally, this is enough. Installing the "Office Data Connectivity Components" (download file name AccessDatabaseEngine.exe) as well as having Office installed corrupts the Jet Driver stack so that SSIS in VS 2008 cannot create the object to read the XLS file. You will see the title error "Unspecified Error" and "80004005" code. Resolution: Uninstall the Jet Engine pack on your development XP machine if you have Office. It will be listed as something like "Microsoft Access Database Engine (2010)". Run Office 200x setup with the Repair option and reboot. Try configuring the task in SSIS and it should be able to read the Sheet names again and columns.  Live Server (32-bit and 64-bit) Deploying your SSIS package to a server without Office 200x means it will not have the Jet Engine drivers to read XLS, XLSX files. You must install the 32-bit Office Data Connectivity Components - Jet Drivers mentioned above found here  (http://www.microsoft.com/downloads/details.aspx?familyid=7554f536-8c28-4598-9b72-ef94e038c891&displaylang=en). There are no 64-bit drivers; therefore regardless of 32 or 64-bit live environments, this step is the same. You shoul

SSIS: Error in the package when the data in the flat file source is modified


Hi All,

I have a package which loads data from a flat file source to an OLEDB destination, which is executed successfully and data is loaded perfectly.

But later when the data in the flat file source is modified i.e. if an extra column gets added to the text file, the package is throwing an error because it is unable to detect the extra added column.

How can i avoid this error??? I need my package to execute successfully ignoring the changes(added columns) happened in the flat file source.

Please provide me wth your suggestions and solutions....

Thanks in Advance!!

SSIS excel data source numeric values returned as null

Hello everyone, long time no see!, I have a problem and was hoping someone can help me:
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.

I tried the answer posted here: http://devselekta.blogspot.com/2007/09/ssis-excel-data-source-values-returned.html but it only works when the first row of data has a number beginning with zero on this column.
Someone knows how to get the data imported correctly? Thanks in advance.

MDW Disk Usage for Database Report Error - A data source has not been supplied for the data source D

Hello, On the MDW Disk Usage Collection Set report, I get the following error when I click on a database hyperlink. A data source has not been supplied for the data source DS_TraceEvents SQL profiler shows the following SQL statements are executed (I've replaced the database name with databaseX) 1. exec sp_executesql N'SELECT dtb.name AS [Name] FROM master.sys.databases AS dtb WHERE (dtb.name=@_msparam_0)',N'@_msparam_0 nvarchar(4000)',@_msparam_0=N'databaseX' this returns zero rows as databaseX does not exist on my MDW central server, but is a database on a target server (i.e. one that is being monitored and uploaded into the MDW central server). 2. USE [datatbaseX] this produces the following error: Msg 911, Level 16, State 1, Line 1 Database 'databaseX' does not exist. Make sure that the name is entered correctly. why is the report looking for the database on my server? thanks Jag Environment: MDW (Management Data Warehouse) on SQL 2008 R2

SQL ServerDestination error - Unable to prepare the SSIS bulk insert for data insertion.

Having searched the forum, this one clearly has form... However beyond assisting those who have fallen at the first hurdle (i.e. forgetting/not knowing that they cannot execute the package remotely to the instance of SQL Server into which they are inserting), the issues raised by others have not been addressed. Thus I am bringing nothing new to the table here - just providing an executive summary of problems which others have run into, written about, but not received answers for.   First the complete error: Description: Unable to prepare the SSIS bulk insert for data insertion.  End Error  Error: 2008-01-15 04:55:27.58     Code: 0xC004701A     Source: <xxx> DTS.Pipeline     Description: component "<xxx> failed the pre-execute phase and returned error code 0xC0202071.  End Error  DTExec: The package execution returned DTSER_FAILURE (1).  Started:  4:53:34 AM  Finished: 5:00:00 AM  Elapsed:  385.384 seconds.  The package execution failed.  The step failed.   Important points It mostly works - It produces no error more than 9 times out of 10. It fails on random dataflows - My package has several dataflows, (mostly) executing concurrently. Where the error occurs it does not do so on the same dataflow each time: on one run it'll fail on dataflow A whilst B,C,D and E succeed, then A-E will all succeed (and continue doing so for the next ten runs thereafter), and

Microsoft Excel and Sharepoint KPI's (External Data Source)

This is my first post i hope i get a clear answer for my question. I recenty have been working on KPI's drawn from Microsoft Excel documents that i created. However, as we know, external data sources in excel don't work with sharepoint. If that was possible it would have saved the company a lot of time and effort My questions are: Is there any way to have external data sources with some advanced modifications, or any other way that would simulate this process? (External data update) Can i directly update my data by tampering the database where the excel file is saved?   I don't know if the files uploaded in sharepoint are stored in a database, so i want some validation around this. (Name of the database, path etc.)   Hope you can shed some light to my questions Thanks in advance Theo

SSIS Excel Connection Manager Data Type Conversion Issues with SS Agent Job

Hi All! I have an issue I've been trying to fix but can't seem to figure it out. I was hoping a kind person would point me in the right direction. :o) I have an SSIS package that uses an excel connection manager source, and I want to run this package through a job scheduled in the SQL server agent. The data types for the excel file fields are 2 (DT_WSTR) and 5 (DT_R8). When I run the package directly through the SSIS package (VS solution) all of the data fields are properly imported into the database table. But...when I run this package through the SQL server agent job, ONLY the string (DT_WSTR) fields in each row are being imported, all of the float fields are imported as NULL. I set the data types for these float fields as "float" in the SQL server import table (data type). Even though the excel source float fields are indicating a type of DT_R8 in the excel connection manager and I set the data types in the SQL server table to "float", I also used the data conversion component and set the type to "float" as a fail-safe. I guess I should add to that the data access mode in the excel connection manager is using a custom code to select only those columns that I needed and to trim rows that I didn't need. Here's my code that I have in the excel source editor: select f1, f2, f3, f5, f6, f7, f8 from [mdo$] where f2 <> 'Rep Name'

Excel Services no refresh data & no error logs

Hi! I'm trying to publish an Excel workbook which loads data from SQL Server. The result is: no data loaded in the workbook and no error logged on Sharepoint logs. Notice that if I try to refresh the workbook in Office Excel all works fine! I try to set up Windows Authentication, None (to use unattended account) and with .odc file but with no result! The procedure I follow is: 1) create a new Excel file and create new data connection to the database (SQL Server 2008) 2) upload the file in the trusted file location 3) open the file in a web part and click on the "refresh all" button I used the same unattended account which I setup for this purpose with BCS and it works fine! I also try to set with PowerShell the Application ID created ("ES"): "set-spexcelserviceapplication -identity 6d871d92-19dd-4421-b33b-0012f9a5ea18 -unattendedaccountapplicationid ES" with no result. I noticed that the identity of the Excel Service application shown in the Central Administration isn't in the IIS Application Pool list: could it be the problem? I also tried to delete / re-create the application but the two IDs remains disequal! Have someone of you already worked with Excel Services and could give me any help? Thanx in advance, Elena
