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?
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.
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'.
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.
I have three control flow tasks that are executing in consecutive order. Tasks 1 and 3 will always execute, but sometimes (based on an expression) task 2 will not. I would like to use precedence constraints in such a way that task 3 will execute regardless of whether task 2 executes, but in the event task 2 does execute, task 3 will only execute AFTER task 2 completes. Is there a way to accomplish this without setting the disabled property of task 2 at runtime?
I have created a task that uses a ForEachFile Loop. Within that loop I load 5 files. Once those 5 files have loaded successfully I want to run a stored procedure. I placed this stored procedure into a script task. The script task has 5 precedence constraints,. They are a success on the load of the files. When I run the task, the 5 files load, but the script task will not start. I have gone so far as to check each load individually to see if it would start the script task, which they do. It's only when I add more than 1 precedence constraint that the script task will not run. The precedence constraints are set to AND, so they all are required. They all succeed. What am I doing wrong?
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.
Hey everyone, I have used the set values option of the execute package utility many times to change values on variables in the package with no problem before, however have run into a stumbling block when coupling this with precedence constraints. I have a package that goes down a different path based on a precedence constraint that works perfectly if the default value of a variable is used....however when I pass in a new value via Set Values in the execute package utility the package will error out with this:
The expression "@[User::IVR_FLAG] == 1" must evaluate to True or False. Change the expression to evaluate to a Boolean value.
IVR_FLAG is an int with a default value of 1, and if left that way(or changing it to another value in the package, as long as the default is used) this error will not occur....it will go down the proper path. But when Set Values is used to run the package to change IVR_FLAG, the above error occurs, which doesn't make sense since the above expression should still evaluate to either true or false. Anyone have any thoughts or suggetions? Thanks, Adrian
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?
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
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.
I have to create an expression that makes bold the text for some possibilities, otherwise the font will keep same, is there any staff for creating an expression like "IF ID_Name IN (x,y,z...) THEN bla-bla" like querying in SQL? Cuz I have to use multiple possibilites for same condition
I am having a problem setting multiple constraints over a table from other table. To be more clear, I have the following code:
ALTER TABLE Solicitud_Servicio DROP CONSTRAINT FK_Solicitud_Servicio_Domicilio;
ALTER TABLE Solicitud_Servicio DROP CONSTRAINT FK_Solicitud_Servicio_Domicilio1;
ALTER TABLE Solicitud_Servicio ADD CONSTRAINT FK_Solicitud_Servicio_Domicilio1 FOREIGN KEY ( ID_Domicilio_Envio ) REFERENCES Domicilio ( ID_Domicilio ) ON UPDATE CASCADE;
ALTER TABLE Solicitud_Servicio ADD CONSTRAINT FK_Solicitud_Servicio_Domicilio FOREIGN KEY ( ID_Domicilio_Facturacion ) REFERENCES Domicilio ( ID_Domicilio ) ON UPDATE CASCADE;
As you see, I want an update on the field Domicilio.ID_Domicilio to change the fields Solicitud_Servicio.ID_Domicilio_Envio and Solicitud_Servicio.ID_Domicilio_Facturacion from my point of view there should be no problem and the weird part is that if I try this with only one constraint (either one) it works, as soon as I try to apply the other constraint I get a very annoying
€œThe referential relationship will result in a cyclical reference that is not allowed€?
Maybe Sql Server Mobile 2005 does not support multiple constraints on a table from the same other table?

Hi, I am getting the above error when trying to load a report into my Web Application, I have tracked the error down to one specific field in my database. Even though this field is a NVarChar field and is of size 30 it would seem that there is an issue returning the value from the field. I can write it into the database no problems but when I try to get it out of the database it returns the above error. e.g MOB 401.908.804 - Fails 0401.907.324 - okay 8239 9082 (pager) - fails Anyone got an idea on how to fix this???? Regards.. Peter.
I know this is probably a flick of a switch but I cannot figure out which switch. Setup is SQL Server / Stored Procedures / DAL / BLL(skipped for testing) / PL. The stored procedure queries from only one table and two columns are ignored because they are being phased out. I can run the stored procedure and preview the data in the DAL but when I create a page with an ODS linked to the DAL and a GridView I get this error. I checked every column that does not allow nulls and they all have values. I checked unique columns (ID is the only unique and is Identity=Yes in the table definition). I checked foreign-key columns for values that are not in the foreign table and there are none. Any ideas why do I get this? Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.
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?
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.
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.
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
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?
SELECT distinct contacts.fname, contacts.lname, contacts.company, contacts.contact_id, contacts.business_phone, contacts.emailAddress, contacts.dateLastContact FROM journal INNER JOIN contacts ON journal.contact_id = contacts.contact_id INNER JOIN products ON journal.product_code = products.product_code WHERE ( journal.product_code IN ('ABLE') ) OR (( journal.product_code IN ('JOBS') ) AND ( journal.product_status IN ('12','14','15') )) OR (( products.prod_design IN ('audio') ) AND ( products.library_code IN ('hrss') )) AND (journal.journal_id NOT IN (SELECT journal.journal_id FROM journal INNER JOIN contacts ON journal.contact_id = contacts.contact_id INNER JOIN products ON products.product_code = journal.product_code where ( contacts.educ_audio IN ('no') ) )) ORDER BY contacts.lname asc, contacts.fname
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?
