Error In ForEach Loop - User::FullResultSet Does Not Contain A Valid Data Object
Nov 23, 2007
Greetings!
I come before you seeking assistance on a package that basically flows very much like the "Table Driven foreach Loops" example provided by Kirk Haselden at http://sqljunkies.com/WebLog/knight_reign/archive/2005/03/25/9588.aspx
I am presently encountering the following exception:
Error: 0x3 at Shred the contents of the variable: Variable "User::FullResultSet" does not contain a valid data object
Warning: 0x80019002 at Shred the contents of the variable: The Execution method succeeded, but the number of errors raised (1) reached the maximum allowed (1); resulting in failure. This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors.
Warning: 0x80019002 at DW CUST_CNCL_ORDhardcodedate: The Execution method succeeded, but the number of errors raised (1) reached the maximum allowed (1); resulting in failure. This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors.
I have a package that starts by loading a recordset into an object variable. The recordset is then enumerated with a ForEach loop. The loop sets some string variables. Within the loop container I have a Script task that uses a MsgBox to show the results for testing purposes. The package uses checkpoint restart (if that matters?).
The first time I run the package the 1st record is displayed in the MsgBox, then the 2nd, but then the loop is stuck on the 2nd record forever. I break the run, and when I rerun it the 1st record is displayed followed by each subsequent record correctly and the package completes successfully. Now, if I were to run again the same problem would occur on rec 2 and I would have to break the run, and then the next run everything would work fine.
Why does the script get caught in an infinite loop the first time it's run, but works fine when restarting from the checkpoint?
Here's my relevant code:
ForEach: Enumerator=ADO Enumerator, Enumeration Mode=Rows in first table
Public Sub Main() Dts.Variables("User::SQL1").Value = "SELECT src.* FROM " & Trim(Dts.Variables("User::Src1Tbl").Value.ToString) MsgBox("sql=" & Dts.Variables("User::SQL1").Value.ToString) Dts.TaskResult = Dts.Results.Success End Sub
I am trying to execute a UDF in an Execute SQL Task within a Foreach loop.
I have an Execute SQL task to get the dataset (Firstname, Lastname, CompanyID) which is going into a full result set called @PendingPar. The Foreach Loop is set to a Foreach ADO Enumerator against @PendingPar and I have created 3 variables at the Foreach Loop scope level called @Firstname (String), @Lastname (String) and @CompanyID (Int32). These are mapped in the Foreach Loop as index 0,1 and 2.
Within the Foreach Loop I have an Execute SQL Task with the sql command
select dbo.udf_GetParTitle (?,?,?)
In the parameter mapping I have Variable Name = User::Firstname Direction = Input Data Type = VARCHAR and Parameter Name = 0, User::Lastname, Input, VARCHAR, 1 and User::CompanyID, Input, VARCHAR,2
Finally the UDF returns a @NewPar value so i have the result set in the execute sql task to Single Row which goes into variable @NewPar. This @newPar will be used later but I cannot get the first bit to work yet.
the error message i get back is
Error: 0xC002F210 at Execute SQL Task 1, Execute SQL Task: Executing the query "select dbo.udf_GetParTitle (?,?,?)
" failed with the following error: "Syntax error, permission violation, or other nonspecific error". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
Task failed: Execute SQL Task 1
the initial execute sql task where the dataset is selected works fine but it is within the foreach loop that it fails.
In my Control Flow, I execute a data flow that opens a flat file and populates the file into a recordset.
Back to my Control Flow, I have a ForEach container that uses a ForEach ADO Enumerator. Inside the ForEach, I execute an "Execute SQL Task" that updates a table.
This is where I'm confused, while in the ForEach, I also want to call a Data Flow and use the current record (record in my ForEach) and perform several lookup tasks. Unfortunately, I'm now sure how to use the ForEach record as a source in my Data Flow....What am I missing?
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!
I am trying to build a Package that selects a list of Uniqueidentifiers by "Execute SQL-Task" and then loops through the ResultSet of the query using ADO.Net Enumerator to do something with this GUID Value, namely deleting all entrys with this PK in a different DataBase.
The main Problem I am facing is that you can“t select the type "GUID" for a user Variable in "Execute SQL-Task". All the Datatypes are there except for GUID!
This leads to the following error:
Error: 0xC001F009 at Package: The type of the value being assigned to variable "User::ImagicID" differs from the current variable type. Variables may not change type during execution. Variable types are strict, except for variables of type Object.
Is this a bug? Or am I doing something terribly wrong?
Hi, I am attempting to create SSIS packages to extract data from our AS/400 DB2 databases and populate tables for analysis and reporting in SQLServer. We have recently installed a new 2005 SQL Server to replace our existing 2000 databases. I have several DTS packages setup to connect to the 400s and copy the needed data to SQL2000 and these work great but do not transition to SSIS very well. I can get my SSIS packages to work if I create a seperate data flow task for each table but that does not seem appropriate for a tool like SSIS. I would think that what I am attempting is a very common thing to do. Maybe other enumerators could be used but I have not been able to get it to work.
I am trying to use a foreach loop, currently with a forech item enumerator, to first truncate the table on the SQL Server database using an Execute SQL task, and the to use a Data Flow task to refresh the data using an ole db source and destination. I have the truncate portion working, but when I try to setup the Ole db source using a variable it tells me I have no input columns. I have a variable from the forech loop that loops through the table names, this variable is used in a second variable which is set to EvaluateAsExpression with the expression set to the follwoing: "select * from " + @table_name
I have set delayvalidation to true and validateexternalmetadata to false. What do I do in order to get around this issue? Also, how should the old db destination be set so that it load the data into the table specified in the variable?
I have created a very simple report that works correctly when in Report Designer Preview mode. When I deploy to the report server it reports that deployment was successful. When I log into Report Manager the report is visible, but when I click on it I end up at an error page.
The error that I get is: Operation is not valid due to the current state of the object.
INPUT: A table contains 2 columns with data i need. column A=Filename and column B=FileContent
PROCESS: I need to loop through ea record in the table and retrieve columns A and B. Then for ea column i need to write the Content hold in column B into File hold in column A.
I so far found out, that i need a Execute SQL Task in Control Flow querying the table and get columns A and B into 2 variables, plus a 3rd var holding the object. Then the output goes into a Foreach Loop Container. From this point i don't know how to continue. I tried to put a Data Flow Task inside the Foreach Loop, but couldn't find out how i now get the 2 variables to the Data Flow Task and use them to for the file to be written and the content to be placed in the file.
Is there any example similiar to that so i could learn how to start on that?
I have a package that runs fine by itself. But when I run it inside a Foreach Loop container on a parent package, I got a buffer error after a few loops. Here are a couple of the error lines:
A buffer failed while allocating 49085616 bytes.
The attempt to add a row to the Data Flow task buffer failed with error code 0x8007000E.
I already played around with the Data Flow tasks DefaultBufferMaxRows and DefaultBufferSize properties, and I am still getting the error. Just wondering if there is a memory leak or something with the Foreach Loop task. I havent install SP1. Maybe SP1 fixes this issue?
Getting Access Denied To FileName Error When Using the Execute Sql Task (With File Connection) into a Foreach Loop Container.
Please Note :
I have a folder containing .sql files. I have to dynamically loop through the files and send them as a File connection Folder to the Execute Sql Task.
When I run this Package I am getting the follwoing error :
[Execute SQL Task] Error: An error occurred with the following error message: "Access to the path 'C:ProjectsFuzzy Lookup DataFlow ExampleScripts' is denied.".
Also I have logged in to the machine as Administrator and to Sql Server with sa.
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 didnt 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
Ive tried putting Execute SQL Task #3 inside of the ForEachLoop, connecting it to the output of the ForEachLoop. Ive 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!
I'm having a problem where I'm using a Execute SQL Task to retrieve a dataset and storing that in an object variable. Then on success of that execute sql task I use a foreach loop task to go through the dataset and do 2 tasks inside the foreach loop. When I execute this package I have ~12 records in the dataset however when I get to the foreach loop in the 2nd iteration it keeps repeating it. It acts like it is stuck on the second record (tuple) and never goes on. I'm using an ForEach ADO Enumerator in the foreach. I've even set a breakpoint on each iteration and no task fails in side the foreach loop. I'm completely perplexed why it will iterate to the 2nd record but get stuck there in an endless loop. I've tried this on 2 different computers (with different data values) and the same thing happens. Does anyone have any suggestions?
I defined Foreach File Enumerator,there are more than 2 files needed to deal with,it donesn't work if i don't specify filename in flat file connection manager editor,however if i specify filename then doesn't foreach files
Trying to through a process together and using the "ForEach Loop" task. When configuring the task and using the ForEach Loop Editor I do not have the "ForEach File Enumerator" in the drop down. Anyone know whats going on or what I need to do to make this appear. I only see 5 selections: ADO, ADO.Net Schema Rowset, Variable, NodeList, and SMO Enumerators. I am also using the SQL 2005 eval with SP1.
Here is what I am attempting to get accomplished. I have an SSIS package that contains a Foreach loop container. This container executes a number of SQL tasks in order: SQL Task 1, SQL Task 2, SQL Task 3.
if the SQL task 1 succeeds it should flow on to SQL Task 2 and 3. This works fine when the SQL tasks do not fail...
In the event of any SQL Task failing control should flow to a send mail task to alert about the failure. Next the Foreach loop container should go to the next enumeration in the Foreach loop container and start the next new SQL task 1. So far I have been able to get the control to flow to the send mail task when a SQL Task fails. What does not work is when one SQL Task fails the entire Foreach loop fails and does not move to the next enumeration. It should only fail the package and move on.
I need to put a FTP task inside a Foreach Loop Container to upload data files to many different FTP servers. The container holds a variable with object data type that includes necessory FTP info (FTP server address, login, password and remote path). How do I configure FTP task so that I can pass the variables to it?
Im new to SSIS and have a question about foreach loop container. Basically, I have 4 data flows and each of them has a variable that need be pass on to the next step, each of the variables will call a same stored procedure. What should I use here? I guess I can use foreach loop container with the stored procedure inside of it, is that right? I tried all day yesterday and cannot make it work. The foreach loop container did not call the procedure at all. Could someone kindly tell me how to do it?
We discovered that the Foreach loop isn't recalculating the number of files found upon each new loop iteration, so if any new files are placed into the receive directory during the looping, they are not detected/processed. is this a bug or product intention?
Can anyone point me to an example of using a ForEach Loop Container to step through the rows in a recordset. I cannot seem to see how this is done from the help files.
I have a foreach loop that is processing files in a directory. One of the tasks is the execute sql task that calls a stored proc. If this stored proc returns a certain value then I need to exit the loop and not process any more files. But I have been unable to figure out how to make this happen.
