Precedence Constraint In SSIS Didn't Work
Aug 27, 2007
Dear all,
I've been searching the article for error handling in SSIS but seems no article have same problem exactly as mine. In my package there's container, it contains Data Flow task and some of Script tasks. I put an error precedence from Data Flow task into Script task that contains script for log an error that might be occured. The Data Flow task imports data from flat file into SQL Server 2005 and I've set a semicolon as the column delimiter. Unfortunately there is a data in flat file that had one column contain semicolon as its value.
This would trigger an error and I hope the error would be logged into a table as I wrote inside Script task. But it didn't work. The error precedence won't work, the package stop in flat file source instead. I've been trying the event handler but it didn't work either. Maybe I got wrong implementation, anybody can help me explain the error handler and solve the problem ?
Here is the capture of my package, since I didn't know how to attach the picture in this forum.
Thanks in advance.
Best regards,
Hery

Greetings,
I have an expression in a precedence constraint that is returning false when it should return true. This is the expression that returns false:
((5500 / 9990) * 100) > 10
The following expression returns true. I did the division (5500 / 9990) myself and substituted the resulting value:
((0.55055055055055055055055055055055) * 100) > 10
Why is the first expression returning false? I'm stuck in the mud up to my axles on this and I know I'll probably feel like a fool when I learn the answer...
Thanks,
BCB

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!

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.

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?
thanks,
J

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

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"?

SQL Server 2005 now provides the ability to use expressions in the plans instead of just the Failed/Success/Completed constraints.
Can anyone tell me what language is used for these expressions. Where can I find a guide on this?
Thanks

Hi,
Whenever I open my package, the Precedence Constraint lines get distorted. This makes my package look messy. Is there any way to stop this from happening?

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 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?

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 created a SSIS package that imports a file then moves the file to a folder called processed.
I created a job that runs the package. The pack works fine when I run it from the SQL Storage Area. When I run the job I get the following message:
Started: 9:58:15 AM DTExec: The package execution returned DTSER_SUCCESS (0). Started: 9:58:15 AM Finished: 9:58:21 AM Elapsed: 6.047 seconds. The package executed successfully. The step succeeded.
showing that the job supposedly completed successfully.
I know that the package the not run because the data did not get imported and the file did not move.
Can anyone explain the package may not run but we still get a job completion status of success?

I have DTSX package where all the Control Flow Boxes are connected by precedence constraints (the Green Lines).
However, only half of them visible!
If I try and add another it says:
Cannot create connector.
Only one workflow can exist between the same two executables.
I don't want to have to drop and create them all the constraints (because there are a lot of them!)
But I can't even do that - since I can't see them, I can't select them; and I don't think I can delete them without being able to select them. Am I missing something? Zooming in makes everything larger, but it doesn't make my Green Lines reappear.
Help!
And yes, I'm using the latest version of everything:-
Microsoft Visual Studio 2005
Version 8.9.50727.762 (SP.050727-7600)
SQL SERVER 2005
9.00.3054.00 SP2 Developer Edition

This is more a medium level annoyance than a problem. When I save a package, close it and later re-open it, the precendence constraints end up all over the place making my neatly layed out diagram a shambles.
Call me anally retentive if you like (you wont be the first ), but I find this extremely annoying. Does anybody else have this problem? Does anyone have a solution?

Hi,
I'm building a package wherein I perform a SQL task(A) if the error log is not empty. This same SQL task(A) is also being used by another data flow task(B). The precedence points from B to A bottom to top. When I execute, all the tasks in the downward direction (precedence pointing downward/sideways) execute but this one doesnt as it points updwards. I can copy and paste task A and make B point to A downward, but I dont want to duplicate A in the same package.
Is there any other approach?
If you dont understand the above, see the flow:
X (SQL task) ----on success-------------> A (SQL task)
| ^
| |
...(sequence of steps) |
| |
| |
B(Data Flow Task) ---------failure --------|
Execution flow doesnt move from B to A, even though its a failure condition. Hope this explains the problem.
Thanks and Regards,
Subha Fernando

Hi!I have a table with a check constraint. But unfortunately it does notwork like I wanted.CREATE TABLE MAP([R_ID] [T_D_ID] NOT NULL,[R_ID1] [T_D_ID] NULL,CONSTRAINT CHECK_ID1 CHECK (R_ID1 = R_ID OR R_ID1 = NULL),CONSTRAINT [PK_MAP] PRIMARY KEY ([R_ID]))R_ID1 should always have the value of R_ID or NullThe following statements should cause errors:insert into map (R_ID, R_ID1)values(1,2);update map set R_ID1=3 where R_ID=1;But there occur no errors. Does anyone have an idea? It is an SQL Server2000.TIASusanne

Note: I'm running a bottom up design on this project as I won't know what data I'm really working with until I can get it imported and analyze it. Also, I'm not a DBA or developer, so please be gentle...
I am importing 30k+ rows using SSIS (OLEDB -DB2- source to OleDB -2k5- destination). The import works fine, but I just realized that I need to set up a pk on the row emp_ids. The problem is that in the DB2 source, the emp_ids were removed (set to whitespace, but not null). So, I can't just uncheck the 'keep nulls' option and import the data.
Any suggestions or links (using SSIS) on how to identify the rows where emp_id = "whitespaces" and 1) either keep them from being imported, or 2) remove them afterwards?
(I suppose this could be done using sql statement to identify the whitespace rows, but that would present difficulties of its own due to the random spacing nature of the updates. Also, I'm hoping for a checkbox wonder solution.)
Please advise. Thanks!

the book "microsoft sql server 2005 integration services" by kirk haselden claims you can download examples and source code at www.samspublishing.com
er no
what happens is this
go to the site
look for the 'downloads' link
see there isn't one
search for authors
h etc.... lose a few minutes of your life
find the book
yay
it forces you to sign up for an account in order to get the samples - outrageous
prepare for endless spam from sams
sign up
click on download samples
find the configedit folder
load into vs
run it
it doesn't work!!
thanks

Hello,
I have configured Kerberos delegation for several web services. One of the web service calls SSIS packages, but the packages don't run with the expected impersonate user : the package starts with the imporsonate user, but continue with ASPNET user (which is not allowed to execute SSIS and connect to DB).
If the web service is called directly (no delegation), SSIS packages run with the correct user. It looks like than there is an autenthicate issue, but kerberos is configured and web services can run from one to another with the impersonate user. The issue occured only when I call SSIS packages.
Here is a extract of the SSIS log file :
