Integration Services :: Precedence Constraint For Sequence Container
May 16, 2015
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 have a sequence container in my Package and this sequence has more than one control flow tasks.
Can I create the checkpoints such that only the failed component inside the sequence container runs again and not the other successful components/tasks in the sequence container?

I have an SSIS package that is pretty simple.
An Execute SQL task returns one row with two values that are correctly stored into variables.
Based off those two variables, a sequence container is chosen to execute.
That sequence container then does magic. The last step of the container has an execute SQL task that runs and stores the result in a variable - let's call this[User::result] with type Int32.
Based off the value in [User::result] one of two final tasks run. A non zero value executes one task; a zero value executes another. Basically,SOMETHING runs after this.
Simple? I thought so... except Step 4 doesn't work. If I set a post-execute breakpoint on the sequence container, the variables are populated as expected, but nothing else runs. If I add another task to run (without a conditional expression) to run after the sequence container completes, the pre-execute breakpoint shows the data looking exactly as I expect.
Those script tasks are just MessageBox.Show calls and the expression, as you can see, doesn't use variables at all.

I have a sequence container with 2 task into. If one of the tasks alert a failure then the sequence container should alert a failure too, but it doesn't. For testing I forced the error with setting the attribute ForceExecutionResult to Failure for one of the tasks. The task fails, but the sequence container succeeds.
I tried:
- changed the Precedence Constraints from AND to OR between the 2 tasks into the sequence container
- changed the attribute FailPackageOnFailure setting True
- changed the attribute FailParentOnFailure setting True
but nothing happened.

I am creating one SSIS package where my source is oracle. I have transferred the data from Oracle to flat file as per client requirement.I have to create single package for 2 country 1 is US and another is CANADA Columns are below
ZONE_ID,
ZONE_NAME
Zone Id having data like 10001,10002,10003,20001,2002,2003
Where zone_id start with 1000 is US Zone and Zone_Id start with 2000 is Canada Zone.
For US:
1. Load geography data from DB tables into flat files
2. Load geography data from flat files to Spectrum DB tables
For Canada:
1. Load geography data from DB tables into flat files
2. Load geography data from flat files to Spectrum DB tables
Now I want to look from flat file if Zone_id start with 1000 then it must go to US_DFT and if Zone_id start with 2000 then it must go to CANADA_DFT.

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.

I am working with SSIS and use Sequence Conatiners extensively. I have become frustrated enought to stop what I am doing and create this thread in the MSDN SSIS forum.
When working with expanded container objects, constraint objects connecting control objects not in the container can be seen. The control object is hidden (sent ot back) but the constraint objects remain visible (sent to front.)
This is extremely frustrating as the unwanted constraint object can be interacted with and not only interfers with the visual presentation during design, it also allows for unintended changes.
I have implemented SSIS upgrades from MDSN but either haven't implemented the appropriate upgrade or an upgrade doesn't exist for this.
Are there any suggestins or comments that can help me get my sanity back?
Yours,

Has anyone ever seen this issue?
If i place a loop container inside a sequence container the connectors within the loop container disappear.... is this a bug - will the loop tasks still run in the correct order?? or will they fire off willy nilly??

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.

I am having a sql query task to fetch a maximun number. Example output : 102. After that I have a for each container to return files from a particular location. Files in the location are for example KAS.JN.101, KAS.JN:102, KAS.JN.103, KAS.JN.104. I want to lpop over only the files which have the ending greater than the maximum number returned from the sql query. In this case, the for each container must only loop over 103, 104. Chow to pass this condition to the container ?

My package is having .csv file as a source and I kept OLEDB destination to load it.
Stored the .csv file in a shared folder and the exact path is given in Enumerator configuration of the foreach loop container. When I execute my package, it is giving the warning as below:
It is saying that file is not there in the specified path and directory is empty. I am running the SSIS package from TFS. I am sure that I have read and write access for the shared folder for my userID. Is there any access there to pick up this file from path.

I use a ForEach Loop Container in a ssis Package. The package has to look up in the directory 'f:ackups' for backupfiles and copy them into another folder.In my development environment it works fine. But if I run it on the SQL-Server with the SQL-Server Agent, the package logs always that the folder ist empty.Unfortunately the message is always 'empty folder' even if I define 'f:labla' as folder that actually not exists!
As filespecification I tried both *.* and *.bak .My assumption is, that the SQL-Server agent has not enough rights for that folder. But on the other side the agent is able to create backup-files in this folder.The SQL-Server Agent works under netservice control.

I have a requirement to load multiple flat files in target table .
I have created the package which used to load files into target table using For each loop container.
But now requirement has been changed now I have to take only those files from table where status="Success" and max JobId. By the query I am to get those records which need to load into table.
Below query I am using to get the files which need to load.
select [JobLogKey],[SrcNm],[DestNm]
FROM [ConfigRep].[dbo].[JobLog]
Where [JobId]=
(Select Max(cast([JobId] as Int)) Jobid
FROM [ConfigRep].[dbo].[JobLog]
Where [JobStat]='Success')
Output:-
JobLogKey SrcNm DestNm
268 H:Data PlatformSource FileClient2LocHGSSpecLocation.txt Location.txt
269 H:Data PlatformSource FileClient1LocHGSSpecLocation.txt Location.txt
I have to load using above 2 files which are under SrcNm. I have created one variable called FileToLoad as Object and mapping to result set of above query. I have create JobId,SrcNm and DestNm variable to catch the record at every loop. I have created 2 For each Loop container
Below screen shot of outer Foreach loop. Till here Its working fine. Inner for each loop container not executing any task under that. How to get it done.

I have a for each loop(ADO Enumerator) container which executes for each Advertiserid which is coming from database. In for each loop I have to create a new excel file with the advertiser name. So if the loop executes 7 times there should be seven excel spreadsheets with seven advertiser names.
How can i create an excel dynamically in the foreach loop container.

Suppose if I have a “Foreach Loop Container” that iterates over a list. Is it possible to execute different data flow tasks based on the input?
Example : List contains elements L1, L2 & L3.
ForEach Loop Container checks the input. If its L1 then it should execute DF Task1, If L2 then execute
DF Task2 and similarly for L3.
Is it possible to achieve this?

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.

For each row coming out of my data source, I would like to add the result of an Oracle query to it (select sequence.nextval from dual).
I need to acquire the sequence number before all my processes in my data flow, so I don't want to have a trigger in Oracle call nextval and do it automatically for me.
I also think getting the value of nextval inside of a variable at the beginning of the process would not work because it only increments the value once.

We have Sequence generator (Next Value) enabled for surrogate keys (SQL Server 2012). When we use the new SCD task, we get the following error:
[Insert Destination [42]] Error: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005.An OLE DB record is available. Source: "Microsoft SQL Server Native Client 11.0" Hresult: 0x80004005 Description: "NEXT VALUE FOR function cannot be used if ROWCOUNT option has been set, or the query contains TOP or OFFSET. ".
Is there any know issue that these two features [SCD task and Next Value] cannot be used together?

I have a SSIS package that needs to run before another SSIS package.
At the moment I have deployed it to the SSISDB, and have set up parameters to enable it run on the right server.
I have not yet experimented with SQL Agent yet, but based on what I have read, it is not possible to do so.
What is the best way to schedule these 2 jobs to run one after the other on a periodic basis using the correct environment and variables set up?
I thought about importing one package into the other, but this creates a copy and any changes to the original will not be replicated.

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.

I am having a challenge to pass the filename variable from SSIS Foreach Loop Container to SQL store procedure. I have an "Execute SQL Task" inside "Foreach Loop Container" which will receive the input filename parameter passed by the Foreach Loop Container. The store procedure command line is defined as "EXEC sp_mySQLStoreProcedure ?" within the "Execute SQL Task". The Foreach loop container will gather the filenames from File System then put it in the filename variable one by one. I would like to pass the filename variable as the input parameter to the sp_mySQLStoreProcedure in the "Execute SQL Task". How can I connect the variable and the store procedure so that it will process all the input files gathered by the Foreach Loop Container?

In order to update an Oracle table target from a SQL Server table source I need to use a Foreach Loop Container, so I can loop on the rows of the SQL Server table source. This source table has two columns: the old identifier to update and the new identifier to apply. I must use the value of the old identifier to filter the Oracle rows to update, while the new identifier is the new value to assign to the filtered old identifier.
I already know how to use the Foreach Loop Container when it is necessary to loop on an unique column of a table/view (using an object variable, using a Foreach ADO enumerator, etc.), but I need to loop on two columns.

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 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.

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

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.
