How To Fail When ForEach File Enumerator Doesn't See Files
Aug 28, 2006
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.
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?
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!
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...)
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.
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.
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)
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
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 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 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 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.
I am using an XML task for validating the XML data against the Schema XSD. I have more XML Files with same the schema. I have to used a for loop container which has an XML task for validate XML. The loop container gets the XML File into variables name "XMLFileName" which the loop current file, in turn, used by XML Task for validation.
XML task is configured in the option "Validate". I have provided the XML Data in variable name "XMLFileName" also get the name from the loop container and XSD file content File Connection. XML Task stored the result in the another variable name "OKFormat". FailOnValidationFail property set to false.
It had the error when I run the package, the error msg as below:
Error: 0xC002F304 at XML Task, XML Task: An error occurred with the following error message: "Data at the root level is invalid. Line 1, position 1.".
Error: 0xC002928F at XML Task, XML Task: Property "New Source" has no source Xml text; Xml Text is either invalid, null or empty string.
Task failed: XML Task
After that, I had to change the source type from Variable to File Connection, and had to test fixed to some xml file it had ok for validate the XML file againt XSD.
I don't know this is the wrong setting or bug of SSIS, anyone can guide me through.
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 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 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.
Is it that I have a syntax error in the nested OPENQUERY or is there another issue? Do I need to specify a different provider in the Server Link such as OLEDB? Non-nested OPENQUERYs work fine.
I'm generally following theTips and Tricks article.
"Executing predictions from the SQL Server relational engine". One problem is the sample doesn't actually complete the example query after the second nested OPENQUERY call.
e.g.
SELECT * FROM OPENQUERY(DMServer, 'select €¦ FROM Modell PREDICTION JOIN OPENQUERY€¦')
The SQL Server server link's provider is configured to allow adhoc access. I appears that the inner OPENQUERY cannot be prepared by Analysis Server or the Server link provider? but I need to return a key value t.[CardTransactionID] for joining to SQL Server data elements.
OLE DB provider "MSOLAP" for linked server "DMServer" returned message "Errors in the back-end database access module. The data provider does not support preparing queries.".
Msg 7321, Level 16, State 2, Line 2 An error occurred while preparing the query SELECT * FROM OPENQUERY(DMServer, 'SELECT t.[CardTransactionID], t.[PostingDate], [Misuse Abuse Profile].[Even Dollar Purchase], PredictProbability([Misuse Abuse Profile].[Even Dollar Purchase]) AS Score, PredictSupport([Misuse Abuse Profile].[Even Dollar Purchase]) AS Suppt, t.[BillingAmount] FROM [Misuse Abuse Profile] PREDICTION JOIN OPENQUERY([Athena Dev], ''SELECT [CardTransactionID], [PostingDate], [BillingAmount], [AccountNumber], [SupplierStateProvinceCode], [MerchantCategoryCode], [PurchaseIDFormat], [TransactionTime], [TaxAmountIncludedCode], [Tax2AmountIncludedCode], [OrderTypeCode], [MemoPostFlag], [EvenDollarPurchase] FROM [dbo].[vMisuseAbuseProfile] '') AS t ON [Misuse Abuse Profile].[Account Number] = t.[AccountNumber] AND [Misuse Abuse Profile].[Supplier State Province Code] = t.[SupplierStateProvinceCode] AND [Misuse Abuse Profile].[Merchant Category Code] = t.[MerchantCategoryCode] AND [Misuse Abuse Profile].[Purchase ID Format] = t.[PurchaseIDFormat] AND [Misuse Abuse Profile].[Transaction Time] = t.[TransactionTime] AND [Misuse Abuse Profile].[Tax Amount Included Code] = t.[TaxAmountIncludedCode] AND [Misuse Abuse Profile].[Tax2 Amount Included Code] = t.[Tax2AmountIncludedCode] AND [Misuse Abuse Profile].[Order Type Code] = t.[OrderTypeCode] AND [Misuse Abuse Profile].[Memo Post Flag] = t.[MemoPostFlag] AND [Misuse Abuse Profile].[Even Dollar Purchase] = t.[EvenDollarPurchase] ')
In desparation I tried returning the case key (CardTransactionID) and the predictive column elements but I get an error when I try that. I assume this is a no-no? OLE DB provider "MSOLAP" for linked server "DMServer" returned message "Error (Data mining): Only a predictable column (or a column that is related to a predictable column) can be referenced from the mining model in the context at line 2, column 15.".
Hi - I'm new to SSIS and am having problems figuring out how to do the following.
I need to load data from flat files into SQLserver 2005 and have created the data flows ok, but my data files are *not* located in a single directory so I cannot use the foreach file enumerator option in the foreach loop container collection. Please correct me if I'm wrong?
My approach has been to execute a SQLcommand to get the filenames from another database table and to use the foreach ADO enumerator option and mapping the returned filenames to a project scoped variable (data type object since it is a rowset).
My problem comes when I edit the properties of the connection manager to try to use that variable for the connectionstring property in the expression editor. I get an error because the datatype of the variable is not supported in an expression.
Can anyone tell me how to correct this or outline another way to solve my problem?
I have a package that loops over ~60 Excel files in a directory. Each file has three named ranges in it, which I import into different tables. Sometimes the package runs without a hitch, sometimes it chokes. But it is intermittent.
If I pull the control flow components out of the foreach loop and point the Excel connection manager to the specific Excel file that has caused the package to choke, I get a message in the dataflow component pointing to the named range that "the metadata of the following output columns does not match the metadata of the external columns......Do you want to replace the metadata of the output columns with the metadata of the external columns?" When I choose 'yes', then the file will be loaded. then I can put the control flow components back into the foreach loop and the file will run again, successfully, along with some more, until it chokes again....
So, first of all, does anyone have any insight into this? Sometimes, somedays, these files will load with no problems. These exact files; I am having to reload constantly... Other times, like today, it is a battle.
Otherwise, is there a way to get Integration Svcs to handle the metadata issue on the fly???
Any ideas, resources, references, war stories, or good clean jokes would be appreciated, Kathryn
My requirement is I have to read 2 sets of files from a folder. For example, I have to read all files starting with either 'a' or 'b' only. In 'Foreach Loop', if I say 'a*,b*', it is not working. Instead of comma (,), I tried colon, semi-colon and pipeline characters also. It is not working. So I am using 2 loops now. But I would like to know is there any way to do it using a single loop?
