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!
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 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.
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
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 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
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.
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 need to execute about dozen packages from another package... how do I dynamically pass the dozen package names to the package and execute using foreach loop...?
idea is to store the names of packages in a text file and set the file connection property reading each package names from the text file... in this way I can just configure/edit the text file from time to time, the packages and the units that I want to execute...
The foreach loop below runs fine and it sends emails as expected but the SP does not update the Companies table. Any thoughts? How do I cause the SP to execute? PROCEDURE newdawn.EmailSentDate @CID intAS UPDATE Companies SET Companies.LastEmailDate = (GetDate()) WHERE tblCompanies.C_ID = @CID RETURN foreach (GridViewRow row in GridView3.Rows) { pstrTo = row.Cells[2].Text; CEmail = row.Cells[2].Text; CName = row.Cells[3].Text; CID = row.Cells[1].Text; CState = TextBox1.Text; CCity = row.Cells[5].Text; CCat = row.Cells[4].Text; CCID = row.Cells[0].Text; SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["localhomeexpoConnectionString2"].ConnectionString); SqlCommand cmd = new SqlCommand("EmailSentDate", con); cmd.CommandType = CommandType.StoredProcedure; cmd.Parameters.AddWithValue("@CID", CCID); try { System.String mailServerName = "mail.domain.com"; REST of code sends email to email address found in each row ....it all works find but SP above does not fire.
Sorry that I open a new thread again but I didn€™t found any good tutorials about foreach loop container. I would like to read every row from one table and do something. I red something about sql task€¦ Can someone give a little instruction, please?
I using data flow task to import from flat file to database but i need to use Foreach Loop Container to import multiple files in specific folder and all will be insert in the same table
Help with Looping in a SSIS Package Scenario: We have a web app that lets our existing clients insert new locations into a table (Clients) in a SQL Server DB. This table has an Identity column as the PK. This table also has another ID field HBID that is the PK for another table (HLocation) in another Database system (Sybase). The HBID field is given a Default value of €˜1€™ during an insert operation in our (SQL Server) table, Clients. The Sybase database uses a Sequence table for inserting a PK into the table. Whenever our clients insert a new record in Clients (SQL Server), I need to generate a new HBID from the Sequence table in (Sybase), update the HBID in the Clients table (SQL Server) and then finally insert the record with the new HBID into table HLocation (Sybase). I have devised a SSIS package for this as following: Note all variables are scoped at the Package Level. Execute SQL Task #1 that drives a For Each Loop with the following properties: General: Connection Type: OLE DB Connection: SQL Server DB SQL SourceType: Direct Input SQLStatement: SELECT COID, HBID, Name, DateCreated FROM Client WHERE HBID = '1'
ResultSet: = Full Resultset
Result Set: Result Name = 0 VariableName = USER::rsClient Variable Type = Object
ForEachLoop with the follwing properties:
Collection: Foreach ADO Enumerator ADO Object Source Variable = USER::rsClient Enumeration Mode = Rows in first table Variable Mappings: Variable: Index: COID 0 HBID 1 Name 2 DateCreated 3
Inside of the ForEachLoop I have another Execute SQL Task to generate a new HBID from Sybase set up as following.
Execute SQL Task #2
Connection Type: OLE DB Connection: Sybase SQL SourceType: Direct Input SQLStatement: UPDATE Autoinc SET INC_LAST = (INC_LAST+1) WHERE INC_KEY ='HBID'; SELECT INC_LAST AS NewHBID FROM Autoinc WHERE INC_KEY ='HBID'
ResultSet = SingleRow
Result Set: Result Name = NewHBID VariableName = USER::NewHBID, VariableType = Int32
Also Inside the ForEachLoop is a Script Task that has all of my variables as ReadWrite = COID, HBID, Name, DateCreated and NewHBID. I concatenate the values in a string a pass the string into a Message Box to make sure they are looping correctly and they are.For example the results might look like the following:
12698, 1, John Doe Trucking, 10/1/2007, 14550 13974, 1, Joe Smith Trucking, 10/1/2007, 14551 10542, 1, Dave Jones Trucking, 10/1/2007, 14552 Etc.
The values 14550 -14552 are the new HBID being generated in the loop.
The problem is that when I try to Update the HBID in the Client table (SQL Server) with another Execute SQL Task I keep getting the same NewHBID number. In this case 14550 would be updated for every record instead of the next number in the loop.
I have set up Execute SQL Task #3 as follows:
General: Connection Type: OLE DB Connection: SQL Server DB SQL SourceType: Direct Input SQLStatement: UPDATE Client SET HBID = ? WHERE HBID = '1'(SELECT COID, HBID, Name, DateCreated FROM Client)
ResultSet: = Full ResultSet
Result Set: Result Name = 0 VariableName = USER::rsNewClient, VariableType = Object
Parameter Mapping: VariableName USER::NewHBID, Direction = INPUT, DataType = Long ParameterName = 0
I€™ve tried putting Execute SQL Task #3 inside of the ForEachLoop, connecting it to the output of the ForEachLoop. I€™ve tried setting up a dataflow with a Derived Column using the USER::NewHBID as the Expression.
I still get the same results, 14550 added to every row.
Can any one help or shed some light?
Any and all suggestion will be deeply appreciated!
