In "Data Flow", I am attempting to use "XML Source" to read a XML document into a recordset and in "Control Flow", into a Foreach Loop Container ( foreach ADO enumerator ), where I map the attributes to DTS variables. SSIS allows you to specify the input columns by means of an index number. The problem is you don't know what index value to use for a particular input attribute. It does not seem to be in the same order as the what the XML input is. This is very troublesome. Ideally, you should be allowed to select the value based on attribute name.
Has anyone seen this problem ? Any ideas ?
Is there anyway in XSD to force the parser to return attributes in a specific order ?
I have been using a recordset destination in a data flow where I need to perform some complex manipulation on a dataset, including combining some information from a web service and updating records that already exist, vs. inserting them.
I have a script task that modifies the dataset as needed, and then saves it back to the variable it came from.
However, when it comes time to write the data to the database, I couldn't find an appropriate tool - there's no "recordset source" object in the data flow task, and use of a "for each" loop with a sql call to a stored proc takes 20 minutes for a few thousand rows.
The best way I could find around this was as follows:
Call the .NET ".GetXML" method on the dataset and put the resulting XML data into a string variable Generate an XSD for that XML (it comes out like <NewDataSet><Table1>...) Use an XML source in the data flow task.This works, and the same data insert that took 20 minutes via the loop / stored procs now takes under 10 seconds.
It seems horribly inefficient to have to do this - there should be a way to just dump my dataset back into a table natively without all that extra stuff.
Ever since installing SQL Server 2005 SP1, when using the Foreach Loop container in SSIS the Foreach File Enumerator and Foreach Item Enumerator are missing from the Enumerator drop down box. Anyone else seen this issue? and know how to fix it?
Would like to do a file System task and a data flow for each row in a table.
I use a ForEach container with ADO enumerator set to a rowset variable. The rowset contains all rows from a single table. What I want to do is as in pseudo-code below:
for each row in ADO rowset
varDestination=CurrentRow.col_file_name.value
FileSystemTask.Destination=VarDestination
FilesystemTask.Copy(Source to Destination)(copy excel file from fixed folder to multiple variable folders)
DataFlowtask.Destination=varDestination(Write data to an excel destination Next My problem is that I dont know how to access the values of fileds from my current row in the rowset. Request help and pointers to samples. TIA Kar
Can someone help me in using the "For each from variable enumerator".
The work around that I have made so far is
1) Generating a Enumerated Value of File collection using Script Control
2) A For each Collection container that processes a given set of files.
the above two conditions works for me when executed independently. But I am not able to relate these two, so as to give a enumerator input to the "For each from Variable Enumerator"
I have been trying to find a way to add the File Enumerator Collection option to my version of BIS. Newer versions have a FileEnumerator and I can't seem to find that option. Can anyone help?
I have built a Table Valued SqlFunction which streams out filtered results from a table. The way that I have implemented this is by using a custom class which implements the IEnumerator interface.
The class internally stores a SqlDataReader and a SqlConnection as private member variables. The Class initializer (ie: the New function) creates a SqlCommand which is executed with ExecuteReader into the SqlDataReader and returns.
The IEnumerator.MoveNext method loops through the SqlDataReader until it finds a result which matches the heuristic filter, and the IEnumerator.Current method returns the current result from the SqlDataReader.
Unfortunately as soon as the initializer returns the SqlDataReader is automatically closed, and I can't figure out why. I've debugged through this and at the end of the Initializer the SqlDataReader is definately open, and as soon as first call to MoveNext is run it is closed.
Can anyone offer any suggestions on how I can fix this.
In the interim i've had to load all of the filtered results into a temporary ArrayList in the Initializer, which defeats the purpose of streaming out the results.
I set up a basic ForEach enumerator loop and specified files of type *.sql.
In the directory, I had some files I needed to keep but didn't want the package to touch, so I changed the extension to *.sqlo. Much to my dismay, the ForEach loop picked up those files. (Though it did skip the *.xml and *.bat and a few other types...)
im using a Foreach ADO Enumerator in my SSIS Package, which iterate on a DataSet from a SQL Task.
I use the "Variable Mappings" on my Foreach Loop to retrieve the values into User-variables. But what i need is a way to combine a value from the DataSet with a User-variable and assign this new value to a new User-variable.
I have a client application that creates a COM object using the program ID 'SQLOLEDB enumerator' to get an ISourcesRowset. Once I retrieve the ISourcesRowset, I call ISourcesRowset.GetSourcesRowset to obtain a list of available servers.
This works if the client computer (the one running the application) also has SQL Server (or SQL Express) installed. But on a clean computer after installing SQLNCLI.MSI, the call to GetSourcesRowset returns an error 80004005.
My question is, what do I need to install on my client's machines so I can retrieve available servers using this method? Is there another MSI that needs to be installed? Do I need to install SQL Express Client_Components? Or is there something else?
Thanks in advance for any information you can provide.
I used the SSIS tutorial just fine with no problems. But then I installed SP1 for SQL2005 and now in the Collection screen for a Foreach Loop Container I no longer have an option for Foreach File Enumerator in the drop down for enumerators. Any suggestions or fixes?
I have a simple ForEach SMO Enumerator that returns the names of all the databases in the server identified by the SMO connection manager. I would like to populate the ForEach collection with just a subset of the names, based on some simple pattern matching. In his helpful book Integration Services, Kirk Haselden indicates that this can be done directly in the Enumerate field by adding qualifiers. However, I'm at a loss in regards to syntax.
What I have is: SMOEnumObj[@Name='Databases']/SMOEnumType[@Name='Names'] which returns the database names
What I want is to limit the names returned to those where Left(DBName,5) == "abcdb" (for example).
I have tried adding some test expressions to the Enumerate field, however, the URN is constructed based on the properties of a combination of the Connection Manager and Enumerate fields, and I'm just created invalid URNs.
Hi: I a SSIS beginner and am hoping this is an easy one. I am using a Foreach loop container with an in-memory ADO recordset as the enumerator. The recordset has 3 columns and one of them I wish to fixup data in by calling a web service task that returns an integer. I see how to call the web service and return the integer into a variable but am unsure how to approach putting that variable back into the in-memory ADO recordset? Should I even be trying to do it this way? thanks! Henry
Is there a way to register a new ForEach Enumerator within SSIS, for example ForEach Email in Exchange Inbox?
Or is the solution to create an SSIS variable and use the ForEach From Variable Enumerator? I take it the variable has to implement IEnumerable, or IEnumerable<T>.
My preference out of the two would be to register a new foreach enumerator which would take some implementation away from the developers and reduce time spent on the tasks at hand.
I am using Sql server 2012. In my project whenever I run the Package individually, it run successfully. But while executing the package through SSIS task, I get the following warning and not able to transfer the data from flat file to DB.
Foreach Loop Container:Warning: The For Each File enumerator is empty. The For Each File enumerator did not find any files that matched the file pattern, or the specified directory was empty.
I have a SSIS package this set to run at a specific time each day. If there are no files for the ForEach tool to work upon...while it doesn't 'fail'...I would like to test for the condition that the enumerator was empty...so that I could send an email message reminding someone to followup and investigate.
What would be the best way to test for that condition?
I have a Foreeach loop container that is looking for all the files in a specified directory. For each file in the directory I need to open the file, extract the contents, and pass the contents as a variable for a stored procedure call.
I was able to loop thru the files in the directory and see each file and store the name to a variable.
I was able to use an XML task to open one file via a file connection that connects to a specified file and store the contents in a variable and then execute the SQL task using the variable.
What I am unable to figure out is how to put the two processes together and get the XML task to open the file by using the variable that contains the filename. If anyone could help I would really appreciate it.
I have a ForEach file enumerator that executes a data flow for every source file in a specified directory. If there are no files in the directory, the package executes with a result code of 0.
I need the package to fail if there aren't any files found in the specified load directory. Is there a simple way to do this with the SSIS component, or will I have to script the entire file enumeration process inside script tasks to handle this requirement?
Thanks in advance for any assistance with this question. Please post replies to this forum.
I will attempt to explain my situation more clearly.
I need to get data from a data source using a DataFlow Task (which pushes the DataSet into a Variable) and process the data row by row in a ForNext (ADO Enumerated) Container. I don't want to map the columns into variables because the number of columns and the data types vary considerably and I want to make my package as "generic" as possible.
Is there a way, in Script, to read the current row of the ForEach Container from into an ADO DataRow so that thie names and values of each column can be accessed?
I know how to read the entire DataSet object from a Variable into an ADO DataSet and iterate through the rows in the normal way but this doesn't suit my purpose. It would be really useful if there was a way to do somehing similar with the current DataRow in the ForEach Container.
To explain what I am doing, the idea is to use the Column Names and Values for each row to construct an xml fragement, store it in a string Variable and (in the next step) use the Web Services Task to call a Web Method with the xml fragment (from the Variable) as one of the inputs.
A less attarctive alernative would be to use a Scipt outside a ForEach Container and loop through the rows of teh DataTable as descibed above and perhaps call the Web Service Task from teh Script. The proble is that I don't know how to do this either and it woudl be much "neater" anyway to use the ForEach Container.
I have a package which contains a foreach container. Can anyone help me in setting the properties for the enumerators programmatically??? I am trying to set the properties for the enumerator "ForEach File Enumerator"
in a my SSIS 2012 pkg I'm using a Foreach ADO Enumerator container that reads an object variable in order to get an id value.This identifier is passed as an input parameter to an Execute SQL task to update an Oracle table: if this task fails the id is written on a SQL Server table. After the Execute SQL task execution, with success or failure, the flow go to another task in the container.
When an error occurs for the update on Oracle table, each tasks inside the container are executed but the container fails and the loop ends.I'd like to complete the entire loop respect to the identifiers present in the object variable also if the update operation on Oracle table goes in error.
How is foreach loop container - foreach ADO enumerator performace in SSIS package compares to use of cursors in stored procedures
Is there any articles comparing them
I understand a lot of factors can affect the performance, however what is expected performance for the foreach ADO enumerator loop for large dataset. What is Microsoft recommendation for that - recommended - not recommended (using large datasets - over million records)
I have no "Foreach File Enumerator" oprtion in the Enumerator Property of the Foreach Loop Component.
I have this enumerator in the c:Program FilesMicrosoft SQL Server90DTSForEachEnumerators folder.
Also I check it in the GAC - it does not here. I try to execute gacutil.exe -iF ForEachFileEnumerator.dll, but it is failed with "Failure adding assembly to the cache: The module was expected to contain an assembly manifest." Seems it is not managed enumerator.
Please help me.
Also information on how to regeister unmanaged enumerators are welcome!
Hi, I'm struck with a small issue.. would be great if somebody can help me out. Here is te scenario
1. There would be more than one CSV files in INPUT folder. 2. I'm using a Foreach Loop file enumerator to loop thru the files and load the data into database. 3. If loading is successful the file need to be moved to ARCHIVE folder and next file needs to be picked up for loading 4. In case if there is an error in loading the file has to be moved into ERROR folder, Error description should be logged to error log text file and next file needs to be picked up for loading.
I don't think increasing max error count is an option as I don't know how many no. of input files are available as it depends upon the feed.
I have a got a package with source as sql table which has got 50 columns. We are using only 10 columns out of this. Recently one column name has changed and thus throws error invalid mapping. When I open the source to do the changes noticed that all the colums are prselected now and also the datatypes got changed to default ( I had changed the datatypes as per my requirement while i developed). So now I had to select required columns from source and redo the datatype changes in advanced editor.Is there any option which doesnt disturb this settings and we just need to correct the mapping alone.
