Failure Precedence On Nested Sequence Containers
Mar 5, 2007
I have a Sequence containser(named One) and 2 Sequence containers( named two and three) nested inside container One. In Container two and three I have execute SQL tasks to execute Stored Procedure. Then I have send email task linked to my sequence containter One on failure constraint.
Failure contrainst to send email is not working. I want each sequence containters(two and three) to execute SQL tasks and if one fails wait for other to execute and then failure task should execute.
Any help is appreciated.

I have about 12 sequence containers mapped out to execute separately based on a precedence contraint and an expression. These lie at the same level and order in my sequence. Only one of these will execute based on an expression. After any of these executes, I have a consecutive sequence container that I'm attempting to execute. I've set the precedence contraint from all twelve of the prior sequence containers to this single sequence container that I would like to run after any of the 12. My problem is that the package will only allow one of these twelve sequence containers to become a precedence of this second single sequence container at a time. The package will let me graphically attach the precedence constraint from all 12 to this single sequence container, but when the package runs, it fails to follow through to this single sequence container. I'm trying to figure out why this is the case and how I can get what I would like to work -- work. Thanks.

There is a bug in SSIS2005 concerning the way that checkpoint files behave in concert with Sequence containers. It is documented (at length) here:
Is it possible to execute a container regardless of the checkpoint file?
(http://forums.microsoft.com/msdn/showpost.aspx?postid=1574262&siteid=1&sb=0&d=1&at=7&ft=11&tf=0&pageid=0)
Is anyone from Microsoft yet able to give a definitive answer to whether this will be fixed or not in Katmai? A yes or no answer would be very very much appreciated.

I have multiple sequence containers in my package. I only want to have one sendmail task for the failure/completion of the package. If I put the sendmail task in the last sequence container and the first seqence fails, the sendmail task will not be reached and therefore, no email will be sent out.Is there a way to have one sendmail task for all the sequence containers and allow it to send mail regardless of what sequence fails/completes?

I have (6) sequence containers, each with a data flow task and script task. The script task renames the file and the data flow uses an OLE DB Source connection to export to a flat file using the Flat File Destination connection.For sI have been unable to move from the 1st sequence container to the 2nd (and the next and so on...). I am trying to do this "on success" (on failure I generate an email notification within each container), but am apparently missing a piece to this because after the sequence container executes, which it does successfully, nothing happens.

I had a Send email task linked to my Sequence Containers in my package and it was working fine. Everytime the container fails it would send an email to myself.
At some point all Failure constraints stopped working. Failure constraints work if I add brand new tasks, but with the existing tasks, they don't work. The Task which fails, turns red and execution stops. Next failure task is not executed.
I am not sure what triggered it to stop working. I cannot get anything on the log
Any help is appreciated.

I have designed an SSIS package that :
(1) contains a for loop task (in which all the logic is contained) that loops through a particular folder for excel files
WITHIN THE FOR LOOP:
(2) pulls data from an excel file into SQL Tables(Data Transformation Task)
(3) run stored proc to validate data (Execute SQL TASK)
(4)ON SUCCESS of executing the SQL Task (Script Task - move file to success or reject folder based on value returned from sproc)
(5)ON FAILURE of executing the stored proc (Script Task - move file to bad format failure)
NOTE:
I have modified the MaximumErrorcount property of (1 FOR LOOP) and (3 EXECUTE SQL TASK) and the package itself to 0.
In order to deal with badly formatted excel files...I do not want the package to stop for every missing tab in excel file or data entry error. I simply want the badly formatted file to be moved to a special folder
PROBLEM:
on failure logic is never executed (I have 2 options after step (3)) on success do step (4) on failure do step (5)
step (3) fails...then it simply iterates to the next file
step 5 is never executed
Is this because I changed the maximumerrorcount property?
What am I doing wrong witht he Precendence Logic?

Is there any differene between on-error event handler and precedence constrain failure? I have created a package and if a data flow task(flat file to DB) fails, the file has to be moved to archive folder. How I have accomplished this is Dataflow task->precedence constrain failed(red arrow)->execute process task to move the file to error folder and it worked,The same execute process task( to move the file to error folder) doesnot work when I move this to on-error event handler. Also, for the same file the on-error event is getting triggered multiple times.

Send Mail task not working properly when it configured in Precedence Constraint (Failure)...
Scenario:
I'm using multiple containers in my ssis package. Also I have configured mail task for capturing error.
I'm getting mail only when error occurs in foreach loop container. If error occurs in other containers it doesn't works.
Actually I would like to receive mail notification on error when it occurs in any of the containers or DFT.

Hi There
I have a package that has many containers that execute in sequence.
If any container fails the package does not fail as the subsequent containers must run.
However if containers fail i do not want to rerun the entire package. Checkpoint restartibility only allows you to start from where your package failed, however my package will not fail and i do not want to start from where it failed but only rerun the containers that failed.
Is this possible ? Can one maybe run only certain containers in a package through dtsexec or another command line tool?
Thanx

Hi All
I am trying to get a list of all the dependencies for objects in a database.
I know about sp_depends however many of the objects are not in the catalogue that the object is in and therefore are not shown.
Any help would be useful

So I have a few data flow tasks that I need to all execute successfully before I commit the changes. So I use a few nested sequence containers with the parent set to Required and all of the children set to Supported. This should work right? Instead I get "The AcquireConnection method call to the connection manager "Databasenamehere" failed with error code 0xC0202009. If I switch the parent back to Supported or NotSupported it will execute fine.
HELP!
Thanks in advance!

Hi all,
I have run into a problem! Im developing a SSIS package programmatically using C#. But when i create and add a container (foreachloop and sequence) the container is not becommming visible in design time in my intergration services designer (when i open the .dtsx package afterwards). Does anyone have a solution to this problem? It is only a problem with containers i create myself (it is working when im adding e.g. dataflow tasks to existing containers).
Sincerely
Bryan

How is the column precedence determined when more then one column is included in the group by clause? I am using T-SQL.
for example:
SELECT VendorName, VendorState, SUM(Invoices.InvoiceTotal) AS InvoiceSum
FROM Vendors JOIN Invoices ON
Vendors.VendorID = Invoices.InvoiceID
GROUP BY VendorState, VendorName
I would expect this statement to group by VendorState first but my result set is grouping by VendorName and then VendorState.
Am I missing something?

Hi there!
I've a few tasks in my dataflow. Some of them are executed depending on an precedence constrain. Works fine.
The problem is following: I want to write a success message (execute SQL task), when all the tasks who have been executed have done this with success. For example, i ve ten tasks, and 2 of them are executed (successfully). This is good, i want to execute my task to write the success message.
I tried to set these precedence constraints with EvalOP = ExpressionOrConstraint, Values = Success and an expression, what returns TRUE, when the task above is not executed (the condition from a precedence constraint above). But the task to write my message will never be executed, because it seems the task does'nt give any result (neither success nor failure) when they ar not executed, and so my AND-Constraint for the success message task will only get TRUE, when ALL task are executed (and successful).
Is there any chance to get somethink like "isSuccess OR IsNotExecuted" into a precedence constraint?
Thanks, Torsten

hi all - this is the first time i've worked with SSIS / Business Intelligence, and I'm having an issue with a piece of basic functinoality.
I'm working with some dtsx jobs which were all conversions from Sql Server 2000 DTS jobs. The conversion process "seemed" to go smoothly. I used the Migration Wizard, and it successfully converted my outputted DTS job files into DTSX files.
In the Business Intelligence design environment (Control Flow) for a specific dtsx package, I have two tasks that are linked together by a Precedence Constraint.
* Task A Truncates all data in Database B --> Table A
* the precedence constraint says that if Task A is successful, then go on to Task B (or at least i think it does)
* Task B copies the newest data from Database A --> Table A over to Database B --> Table A
Everything appears to be correct, but if i right-click Task A and perform an "Execute Task" command, Task A will run successfully, but then stops short without running Task B.
Are there any common "gotchas" or issues that I might be missing which would cause this behavior? I deleted the existing precedence constraint, and added back a new one with the same settings, but Task B still will not run.
thanks for any help on this

Hello folks,
I have probably a dumb newbie question but I can't find the answer anywhere.
On my Control Flow design pane I have two objects: a SQL task object and a Data flow task object. The first 'points' to the second. From my digging I believed that by indicating with the arrow from 1 to 2 that 1 would execute to finish before 2 was started.
My SQL taks is to truncate a table to receive the new data coming from the data flow task object. Instead 2 executes first and then 1. You can imagine producing an empty table was not my goal for this package.
Can anybody give me a clue?
Thanks....
Jim

Hello,
I've recently begun exploring Integration Services and have a question regarding a Control Flow element.
I'm trying to understand precedence constraints. Specificially, the logical AND and logic OR components. If I have two constaints A and B where A is using a logical AND and B is using a logical OR, how are the constraints evaluated? The Evaluation Operation is set to "Expression and Constraint" for both constraints.
If my understanding is correct, path A would be followed if both A AND B are true. Path B would be followed if A OR B is true. Is this correct?
Regards,
Orlanzo

I'm having problems with the query below. It works fine until the "NOT IN" part and I'm not sure why. Basically, I'm getting records where their educ_audio field is set to "no". I've messed with the parens to try to force SQL to process the NOT IN part before the other clauses without avail. Can someone shed some light?
TIA

I have two packages - one works, the other doesn't. Both have two tasks: an Execute SQL Task and a dependent Send Mail Task. I am using a precedence constraint where the evaluation operation is an expression evaluating a variable created by a select count(*) as variable in the query. Both variables are defined as int32, initial value of 0 with a scope for the entire package.
The expression that works tests for an error_counts > 0 condition; the one that doesn't tests for load_counts < 24. The > 0 sends mail when the error_count is greater than 0 but doesn't send mail when it is 0, which is as I intended. The less than 24 package always sends mail even though the variable resultset_singlerow is usually 24. When I look at both properties for the Execute SQL Task steps side by side, they have no differences. When I look at the properties for the constraint, the only difference is in the EvaluatesTrue, which is set to False for the one that works and True for the one that doesn't. Unfortunately, that property is grayed out (not modifiable) and doesn't seem to be an option when I edit via the Precedence Constraint Editor.
I've looked a Books Online & Google with no references to a similar situation. Does anyone have a solution? Is the EvaluatesTrue the problem? And if it is, how can I change the setting? If not, what is the problem?
Thanks in advance for any help.

An application filters records based on names found in them. Forexample, looking through property buyer names, looking for banks andrelocation companies.I have a table of names and patterns:CREATE TABLE #Filters (Pattern varchar(100), IfWildCard int, Categoryint)INSERT #Filters SELECT 'Bank Of America', 0, 1INSERT #Filters SELECT '% Bank %', 1, 2INSERT #Filters SELECT 'Bank %', 1, 2INSERT #Filters SELECT '% Bank', 1, 2INSERT #Filters SELECT 'Credant Reloc%', 1, 3INSERT #Filters SELECT '%Relocation%, 1, 3The filtering matches the table of candidate names against the filters,and returns Category, where the where clause or join is(Candidate = Pattern AND IfWildCard = 0)OR (Candidate LIKE Pattern AND IfWildCard = 1)"Bank of America" matches an exact pattern, and also a wildcardpattern, and the two different matches give different values forCategory. Is there a way to control which match takes precedence, oris necessary to do it multiple times in the desired order, removingthose that hae already matched from consideration?Thanks,Jim Geissman

Has anyone seen precedence constraints disappear in a package after closing and opening again? In this case, it's not package-wide. Only constraints inside one Foreach Loop container disappeared. Any idea what causes this to happen?
p.s: Yes, I did Save All. Most of these contraints were saved in the package for more than a week anyway.

Hello,
I have a SQL Task the executes the following statement;
SELECT COUNT(SettleDate) AS CountResult
FROM SettleDateCount
I have the SQL Task Editor configured for a Single Row result set. The Result Name is CountResult, and the variable it populates is RowCountRes. RowCountRes is Int32 with EvaluateAsExpression set to False.
I have a boolean variable called RowCountStatus. It evaluates as the following expression;
@[User::RowCountRes] > 1
From the SQL Task, I have two different constraints, both of which evaluate with an expression. One constraint evaluates this way; @[User::RowCountStatus] = True
The other evaluates this way; @[User::RowCountStatus] = False
The idea is that if the count comes back from the sql statement greater than 1 then execution continues down one path, else it goes down the other path. Currently, the result comes back = 1. I expect that the 'False' path will execute, but the 'True' path executes instead.
What am I doing wrong?
Thank you for your help!

I have three sequence containers setup to run in parallel. I have a final step that parses the log file and displays results, and I want to this to occur when all three containers have completed, success or failure. I therefore have a constraint from each container that feeds into my final step, and all three constraint types are set to "completion".
When I run the package and one of the tasks within a container fails (and fails its parent, but not the package) the final step is not executed.
If I take off all the constraints except one, the final step is executed as expected.
I am using checkpointing if that has any impact. Disabling it makes no difference.
Any thoughts/alternatives I might try?
thanks

Hi,
I have 3 data flows connected sequentially on my workflow before processing dimensions and facts which checks data from different databases and if conditions does not meet then writes to log table. So if it writes to log table , I have to quit and finish the workflow.
How can I do that?

Hello,
I have a package that executes 2 sql tasks then another SSIS package. My precedence constraints between sql task 1 and sql task 2, and sql task 2 and the SSIS package check that @ErrorValue == 0.
@ErrorValue is set after each sql task (both of which execute stored procs) with the value of the output parameter for the stored proc. I have run both stored procs on the server and both return 0 in the output parameter.
When I run the package the two sql tasks execute as expected (tasks turn green indicating success) but the package stops at that point and the SSIS package task never executes.
If I remove the second sql task and connect the first sql task to the package task with the @ErrorValue == 0 precendence constraint the package task still does not execute (even though the constraint worked to get the sql task 2 to execute).
The package only runs if I remove the expression in the second precedence constraint (between sql task 2 and the package) thus changing it to simply 'on success'.
Please help!

Hi all
I've got a package that checks the length of chars in a flatfile and if it's correct it executes the dataflow task.
How can i write an expression in the precedense constraint editor to skip the dataflow task if there is an error in the script task?
Thank you

Is it possible to use objects in precedence constraints? For example, I have a collection object that may or may not be populated in a script at some point and want to be able to execute different paths depending upon whether the Count property equals zero or not.
I realize I could very easily just create another int variable and populate it accordingly, but I am just curious about this. I couldn't get it to work, but then I am really just starting out here and just not sure if I am doing it wrong.
Thanks!

I am struggling here with precendece constraints and variables.
I have the following scenario:
Task A
Task B
Task C
@var1!=0
@var1==0
Task A, Task B and TaskC
Task A (Execute SQL Task which assigns a value to a variable say, var1) determines if TaskB will execute i.e.
IF var1 !=0 Execute Task B and then Execute Task C
IF var1== Execute Task C
Is this possible in SSIS?
Problem:
Each time I try to do this, the package never executes Task C. It always either Executes Task A or Task A and Task B.
For example if var1 !=0 it executes Task A and Task B
but if var1 == 0 it executes only Task A.

I am confused with Precedence constraint editor regarding Evaluation Operation and Multiple Constraints options. In the Evaluation Operation dropdown list, there are: Expression and Constraint and Expression OR Constraint. Why it still needs LOGICAL AND and LOGICAL OR in the multiple constraints options? Is it clear that Expression and Constraint is "LOGICAL AND" and "Expression OR Constraint" is "LOGICAL OR"?

hi all,
i have a package here which updates a DB from a flat file source.now the problem is i may get multiple files.i have used a for each loop to handle this. it takes files based on the files name9(file names has a timestamp in it).but i want to give files in order of its Creation time.
Please help me on this.i have written a script task before the for each loop and i have got the minimum creation date from all the files,i am not able to going forward from here.

Dear Friends,
In my controlFlow I have 2 sequence container... Sequence1 goes to Sequence2 if an expression valuate to TRUE.
If the expression value is true, than there isn's any problem and sequence2 runs, but if the expression is FALSE the sequence2 container doesn't run.
OK?
In the case of expression valueate to FALSE I need to generate an error or an information in order to get it in the eventhandler automatic...
I can add a script task to make the package failure... but what I insert in the precedence constraint editor from Sequence1 to the scripttask?
Imagine... the expression from Sequence1 to Sequence2 is a>=b
The expression from Sequence1 to ScriotTask os a<b? (How can I define this only to run when the expression (seq1 to Seq2) is false??
Someone know how?
Regards!
