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 greyed 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?
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.

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?
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"?
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??
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?
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.
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 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...
(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.
I am trying to create table with following SQL script:
Code Snippet
create table Projects( ID smallint identity (0, 1) constraint PK_Projects primary key, Name nvarchar (255) constraint NN_Prj_Name not null, Creator nvarchar (255), CreateDate datetime );
When I execute this script I get following error message:
Error source: SQL Server Compact ADO.NET Data Provider Error message: Named Constraint is not supported for this type of constraint. [ Constraint Name = NN_Prj_Name ]
I looked in the SQL Server Books Online and saw following:
CREATE TABLE (SQL Server Compact) ... < column_constraint > ::= [ CONSTRAINT constraint_name ] { [ NULL | NOT NULL ] | [ PRIMARY KEY | UNIQUE ] | REFERENCES ref_table [ ( ref_column ) ] [ ON DELETE { CASCADE | NO ACTION } ] [ ON UPDATE { CASCADE | NO ACTION } ]
As I understand according to documentation named constraints should be supported, however error message says opposite. I can rephrase SQL script by removing named constraint.
Code Snippet
create table Projects( ID smallint identity (0, 1) constraint PK_Projects primary key, Name nvarchar (255) not null, Creator nvarchar (255), CreateDate datetime ); This script executes correctly, however I want named constraints and this does not satisfy me.
We are using SQL CE 3.5 on tablet PCs, that synchs with our host SQL 2005 Server using Microsoft Synchronization Services. On the tablets, when inserting a record, we get the following error: A duplicate value cannot be inserted into a unique index. [ Table name = refRegTitle,Constraint name = PK_refRegTitle But the only PK on this table is RegTitleID.
The table structure is: [RegTitleID] [int] IDENTITY(1,1) NOT NULL, [RegTitleNumber] [int] NOT NULL, [RegTitleDescription] [varchar](200) NOT NULL, [FacilityTypeID] [int] NOT NULL, [Active] [bit] NOT NULL,
The problem occurs when a Title Number is inserted and a record with that number already exists. There is no unique constraint on Title Number. Has anyone else experienced this?
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.
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.
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?
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

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.
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.
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 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 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
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 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?
