I have a simple data flow where I am trying to import data from an xml file into a SQL Server table. I have an xsd that seems to work because the XML Source can pick up all the elements in the xml file. The problem is that the process executes successfully without any rows being imported. The xml file has lots of data. But no messages or warnings are given to suggest why no rows are being written to the table.
I am new to SSIS and I am trying to do following thing using WMI Reader Task.
I have developed SSIS package which import data from flat files. Now I have to add following functionality to SSIS package
Before SSIS package load data I would like to check If there are all files in source folder and check the files are with current date. If both condition true then only load data.
After some research i found that WMI uses specialized query language known as WQL, which is similar to SQL, to obtain information on files and directories.
Also i found that Under WMI Reader Task editor properties you can write WQL query to receive file information from source folder.
Can Anyone suggest me What WQL query i have to write to retrive file information from Source folder?
Or
Any Other suggesion i should approach?
Please advise me!...Any help would really appriciated...
At our business we are getting a lot of PDF documents that are being hand keyed into a database. Has anyone heard ior know of a SSIS Data Flow Source component that I coud use to read thos documents into a data stream (?) and process?
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.

This is my first time trying to import data from an XML file. It seems wonderfully straightforward. I currently have my Data Flow set up correctly. However, when I try to run my package I get a series of errors. One error is a 0x80131500 which is a very generic error. It say's it's haveing a hard time with a 'Url' field in the XML. The size of the field is set to 255 which should take care of any issues with Truncating. The only issue that I can see with that field is that it contains a query string which of course contains a special '&' XML character (&). When I set the Error Handling to Ignore that Error on that column, it imports just fine, however, NONE of the URL's get inserted. So there must be a problem with every URL in the XML. Here are the error messages I recieved from the Progress section:
[XML Source [1]] Error: The "component "XML Source" (1)" failed because error code 0x80131500 occurred, and the error row disposition on "output column "Url" (59)" specifies failure on error. An error occurred on the specified object of the specified component. [XML Source [1]] Error: The component "XML Source" (1) was unable to process the XML data. Pipeline component has returned HRESULT error code 0xC0209029 from a method call.
----And then alot of DTS.Pipeline errors.
I have done alot of searching for this error in regards to SSIS, but the information is scarce. Any and all help would be greatly appreciated. Thank you for your time in this matter.
P.S. Just started using SSIS last week and I love it! The team did an excellent job!
I wonder if anyone can tell me how we can run select queries in an OLE DB data flow task and tell the target SQL 2000 server it should allow reads at all time. Currently when a lock is on the source table our SSIS package will sit and wait untill the lock on the source table is gone.
I have read only permission in the source (OLTP) database. The source database is running in SQL Server 2000 and the size is more than 200 GB. I need to pull data from source and load target which is running in SQL server 2005.
Following are the objectives I want to achieve.
Data should be loaded on incremental basis.
Whatever changes take place (Update/Delete) in source, that should be replicated to already uploaded data.
Here I want to mention that, the source database does not have any identification key or timestamp column like Updated_Date by which I can filter the data which are recently inserted or updated into the source and upload the same. The source does not maintain any history data also. So I do not have any track of deleted record also.
I don€™t have any scope to change the schema in the source. In this scenario can anybody suggest me the best approach to achieve the above mentioned objectives?
Can I retrieve only the recent updated or inserted date form transaction log back up. Can log shipping solve the give the solution?
One more question. Say I have a table and I am exporting/importing all the data from/to my target table using SSIS or DTS. In this scenario does using query or using directly the table affects the performance?
I have a problem with reading data from an Excel file in SSIS. I'm trying to read a column that mostly consists of decimal values, but there are couple places where column entry is 2 numbers separated by a slash (e.g. "100/6.0"). SSIS tries to be smart and identifies the column data type as decimal and when it reads the cell with the slash in it, it reads as NULL. I tried to make my excel source reader component to read that cell as a string, but it gives me an error. If anybody has come across something like this, I would highly appreciate some help
Hello Experts, I am createing one task (user control) in SSIS. I have property grid in my GUI and 2 buttons (OK & Cancle). PropertyGrid has Properties like SourceConnection, OutputConnection etc....right now I am able to populate Connections in list box next to Source and Output Property.
Now my question to you guys is depending on Source Connection it should read that text file associated with connection manager. After validation it should pick header (first line of text file bases on record type) and write it into new file when task is executed. I have following code for your reference. Please let me know I am going in right direction or not.. What should go here ? ->Under Class A
I have a filetable that contains a binary file. I need to do a selective read of the file stored in the file table. I can write a C# CLR function that will open the file, read n bytes the from a starting byte. Or I can write a SQL statement that reads the stream in the filetable into a VARBINARY variable using SUBSTRING beginning at the starting byte (offset from 1) for the same n bytes.
Both give me the same result. However, the SQL statement takes considerably longer to read. I know there is overhead in reading through SQL (interpreted language), but the difference in performance is substantial, and I can only attribute this performance degradation if SQL first tries to "load" the entire stream before it identifies the portion of the stream that it needs to read beginning at the starting byte offset.
I wonder if this is the case or if there is another option to read a stream from a filetable directly through SQL queries that is more efficient.
Hello, I am trying to configure a Script Component as a data source. Although this should be a simple exercise, I am running into a problem.
My control flow contains a Foreach Loop with a file iterator. The Directory Expression of the Foreach Loop Editor is supplied by an expression mapped to a package level variable called inputdirectory. The FileNameRetrieval Expression is mapped to a package scoped variable called filename.
My data flow is encapsulated by the Foreach Loop, and contains a Script Component as Source for the Data Flow Source, and a Flat File for the Data Flow Destination. The contents of the Script Designer are as follows:
Code Block Imports System Imports System.Data Imports System.Math Imports Microsoft.SqlServer.Dts.Pipeline.Wrapper Imports Microsoft.SqlServer.Dts.Runtime.Wrapper Imports System.IO Public Class ScriptMain
Inherits UserComponent Dim thisFileDate As Date Dim thisFileName As String Dim thisFilePath As String Public Overrides Sub CreateNewOutputRows()
thisFileName = ReadOnlyVariables("filename").Value.ToString() thisFilePath = ReadOnlyVariables("inputdirectory").Value.ToString() thisFileDate = File.GetCreationTime(thisFilePath & "" & thisFileName) FileSpecBuffer.AddRow() FileSpecBuffer.FileName = thisFileName FileSpecBuffer.FullPath = thisFilePath & "" & thisFileName FileSpecBuffer.CreateDate = thisFileDate End Sub End Class
When I debug the package, I get the following error:
The collection of variables locked for read access is not available at this point.
at Microsoft.SqlServer.Dts.Pipeline.ScriptComponent.get_ReadOnlyVariables()
at ScriptComponent_67311120e6eb4162a3ea1f70847f04de.ScriptMain.CreateNewOutputRows()
at ScriptComponent_67311120e6eb4162a3ea1f70847f04de.UserComponent.PrimeOutput(Int32 Outputs, Int32[] OutputIDs, PipelineBuffer[] Buffers)
at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.PrimeOutput(Int32 outputs, Int32[] outputIDs, PipelineBuffer[] buffers)
My googlefu fails me at reconciling this. I have read various posts about changing the line ReadOnlyVariables("filename").Value to ReadWriteVariables("filename").Value, and handling the buffer assignment in PostExecute. The problem is that all examples shown are either for Script Component as Destination or Script Component as Transformation. I have tried playing with the Custom Properties in the Script Commponent set the ReadOnlyVariables and ReadWriteVariables, using a PreExecute method, a PostExecute method, all with different errors returning. I'm at a loss here. Could anybody provide me with a simple working example so that I can correctly populate my output buffer in the context of Script Component as Source?
I fully understand that I could just run a Script Task Using System.IO.Directory, and System.IO.File, but I really want to make this package work in the manner I've described. Any help would be appreciated.
All examples I found refer to classes under Microsoft.SharePoint namespace. However, I have the SharePoint CSOM that only gives me the Microsoft.Sharepoint.Client namespace.
I need to read the selected values of a multichoice field, but not sure how to do it with classes in the namespace above.
everthing works, exept the TSQL_x0020_Reference_x0020_Numbe field.
I am trying to create a program that transfers tables to flat files. At this point in time, I have suceeded in created one that creates delimited files.
However, I am now trying to create fixed-width files as you can do with the SSIS designer, but programatically.
Is there a way to programatically determine the width of a column from the source table? I can not seem to find any kind of function or member that stores this information or allows me to retrieve it.
I know what I need to change in order to set a width for a column, but I just don't know how to find the width without just asking the user to provide one.
I then use the XML source connection to connect to it. It sees all of the columns correctly, but when i run and put a watch on it, or try to output the results to a .csv file, no records come through.
Any ideas on why there aren't any rows comming through? i'm using SQL2005 with no SP1
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 created a File System task which is contained in a Foreach Loop Container. I have .bak files that are populating a directory from a maintenance backup plan.
There is a point where I need to delete the .bak file's after I've zipped them all up.
How do I set the SourceVariable to read through the directory and pick up just the .bak file's in the directory to delete.
I am having a brain-fart or something. I need help!!!
I'm developing a transform that selects data from a SQL script, then transforms that data, and then needs to update the data back into the same source table. The transform is working great, but I can't figure out the update table part. I've got it adding the transformed records to the table, but that's not what I need to do. I need to update the table with the changed data.
Any sample code or blog links would be greatly appreciated!
I have created a data warehouse that pulls information from an ODBC source into a SQL database. The schema in the destination matches the source, and the packages clear the destination tables, then append all the records from the source. This is simpler than updating, appending new, and deleting on each table to get them in sync since there is no modify timestamp in the source.
There are cases where I just want to append records from the source table that do not already exist in the destination table, without clearing the destination table first.
How can this be done with a SSIS job? Also, how can the job be run from a Windows Forms application?
It would be a stored procedure that would read the XML attributes into 2 tables, the number of attributes could be 1-N, so I thought XML would be a good choice. Also, one of the attributes could be up to 4000 characters. I think this may limit our options, can 100-150 4000 character strings be passed in a standard call to a query/proc in SQL?
Currently the client application makes round-trip network calls to save upwards of 100 pairs of data. 1 header row, and many detail rows. All within a transaction.
I think If we move an XML file to the SQL box, then do all the import/save work on the "Server" side it would be much better. Cutting the transaction time down a lot by not doing so many round-trips at network speed...
I have a source files folder where the files generated everyday. My goal is pick the latest file and copy this single file to another folder. I used the Foreach loop container and got the latest file and stored the file name to a varible i.e. LatestFile Then i want to use the File System Task to copy this to the destination. On the beginning, I could not setup the Latestfile since I don't its name then, so when I setup the Source Connection property of the File system task, it is not allowed to leave the SourceVarible as blank!
I have a XL source file which contains the 1st column value is some of Numeric and alpha numeric (ex. 1,1A,1B,2,2A,2B), i have fired the select statement (select * from [sch 1 a$A9155] where f1 is not null ) in XL source editor, its not showing the numeric records means 1 and 2 were excluding from the above select statement i think it was due to combining numeric and alpha numeric.
I need both records should select , please anyone can help me to sort out the issue.
Hi, I have an SSIS package that runs each day from a live data source to create a data mart, which is then used for various things including SSAS and SSRS.
The problem is that certain records that will eventually go on to form fact tables are deleted from the live system (not a very robost database in the first place, hence the SSIS!) but these are not reflected in the SSIS transformation, creating plus figures when compared to the live system.
I currently use type 1 slowly changing dimension processes in each data flow (of which there are about 35) but I realise that this only updates records and does not delete.
The solution I have in place is to truncate the fact tables in the mart before the run starts using an Execute SQL task. This solves the problem though to me seems a little heavy-handed and renders the slowly changing dimension processes redundant (as it is currently only run once a day).
My question is, is there a better method of dealing with the above scenario? If there isn't, it would be a nice feature to add to future versions (*nudge nudge*).
I am using a XML source and an oldedb destination to load an XML file into a database, the XML and corresponding XSD are provided by a different system and I dont have any control on them.
In the data flow I can see all the tables in the schema and I can map the columns, however when I run the package it validates fine, and then completes without going into the execution mode, its all green but doesnt load any data. Its weird and I cannot figure out if it is an XML or XSD problem, any idea?
[DTS.Pipeline] Error: "component "Excel Source" (1)" failed validation and returned validation status "VS_NEEDSNEWMETADATA".
and also this:
[Excel Source [1]] Warning: The external metadata column collection is out of synchronization with the data source columns. The column "Fiscal Week" needs to be updated in the external metadata column collection. The column "Fiscal Year" needs to be updated in the external metadata column collection. The column "1st level" needs to be added to the external metadata column collection. The column "2nd level" needs to be added to the external metadata column collection. The column "3rd level" needs to be added to the external metadata column collection. The "external metadata column "1st Level" (16745)" needs to be removed from the external metadata column collection. The "external metadata column "3rd Level" (16609)" needs to be removed from the external metadata column collection. The "external metadata column "2nd Level" (16272)" needs to be removed from the external metadata column collection.
I tried going data flow->excel connection->advanced editor for excel source-> input and output properties and tried to refresh the columns affected. It seems that somehow the 3 columns are not read in from the source file? ans alslo fiscal year, fiscal week is not set up up properly in my data destination? anyone faced such errors before?
