I have one Data flow, which trasfer data into two table (Parent & Child) .
My question is : Is there a way, i can load data first into parent and then child table. because child table getting load first after that parent table loading. (Execution should be Source Parent --> Destination Parent) First , (Source Child --> Destination Child) Second.
In my case its executing reverse. So i have foreign key constraints at child table , its giving foreign contraints error while running ssis package
Can any one tell me,
How to define my own sequence execution at the Data flow task (Source - Destination) ?
I am creating a staging database in which I am loading required tables from 2 different sources. I have 30 different tables to load from source 1 and 10 different tables from source 2. This is the way I am doing, in Control flow task I am using Sequence container and in that I included the data flow task, the data flow task has source OLD DB connection from where I select the table and then destination OLE DB connection where I load the data. So for 30 tables I have one Sequence container with 30 different data flow task and each data flow task has OLE DB source and OLD DB destination. I wanted to find out if this is the efficient way to do, or if there is any other way to do this. And for source 2 shall I put in another package or shall I use the same package with different sequence container and follow the same steps as for Source 1 tables. Please advice. Thanks,
I have a package that loads staging tables from an Oracle source DB. In the data flow tab I have 30+ read table/write table task combinations. When I run the package 3-4 of the read/write combos execute at a time. What I'm trying to control is the priority order of the combo execution. My goal is to minimize to total load time by having the larger table transfers run first and the smaller table transfers fill in until they are all complete. Currently, the largest table (16 million) transfers last (because it was the last combo that I created?).
I got a serious problem with an SSIS-Import. My packages import from a foreign source into a kind of temp-table (actually it's not a temporary table, itīs just filled with data and truncated after completion of the package), do some transformations and then I got a data flow task that simply copies all the rows from the "temp" to the final table. I get the following errors (here there are two simultanious copy operations from two different "temps" into the same final table.

Well, it looks like those two processes simply deadlock each other. But there are 11 Simultanious Data Imports which all go fine. The Issue only occurs at those two. The structure of the packages is exactly the same everywhere.
Is it possible that a previous update-sql query hasenīt committed properly and locks the datasets?
Hi, I'm trying to implement an incremental data pull (Oracle to SQL) based on Andy's blog: http://sqlblog.com/blogs/andy_leonard/archive/2007/07/09/ssis-design-pattern-incremental-loads.aspx
My development machine is decent: 1.86 GHz, Intel core 2 CPU, 3 GB of RAM. However it seems the data flow task gets hung whenever I test the package against the ~6 million row source, as can be seen from these screenshots. I have no memory limitations on the lookup transformation. After the rows have been cached nothing happens. Memory for the dtsdebug process hovers around 1.8 GB and it uses 1-6 percent of CPU resources continuously. I am not using fast load to insert new records into my sql target table. (I am right clicking Sequence Container 3 and executing this container NOT the entire package in the screenshots)
The same package works fine against a similar test table with 150k rows. http://i248.photobucket.com/albums/gg168/boston_sql92/7.jpg http://i248.photobucket.com/albums/gg168/boston_sql92/8.jpg
The weird thing is it only takes 24 minutes for a full refresh of the entire source table from Oracle to the SQL target table. Any hints,advice would be appreciated.
I'm trying to conditionally execute a dataflow based on the presence of a data file. If the data file isn't present, I'd like to execute gracefully without error.
Logic is as follows:
If FileExists Then execute dataflow Else exit w/o error End If
I've got the code ready to go, but I'm not sure how to do this conditional branch logic. Right now, the code calls the Dts.Results.Success / Failure. The problem, however, is Failure is exactly that... which doesn't result in the graceful exit I'm looking for.
I would like to know different possible ways in appending extra values like new uniqueidentifiers, sequence numbers, random number. Can you please tell what type of data flow components helps us ?
I am trying to create a simple BI Application for SSIS. In Visual Studio 2005 I just get a Data Flow Task from the toolbar and add it to the project. When I double click it I get the following error:
The task with the name "Data Flow Task" and the creation name "DTS.Pipeline.1" is not registered for use on this computer.
Then when I try to delete it it gives this other error:
Cannot remove the specified item because it was not found in the specified Collection.
I am creating this application in an administrator account in this computer, so I doubt the problem is related to permissions. I am running SQL Server 2005 and Visual Studio 2005 in WinXP Tablet PC Edition.
Any suggestions why this is happening and how to fix it?
I am using SQL 2005 SSIS. I am joining several large tables and then the move result into another table in the same database.
I would like know which method is faster:
Use Execute SQL Task to insert the result set to the target table
Use the Data Flow Task to insert the result set to the target table. (Use OLE DB source to execute SQL command and then use the SQL destination) Could you tell me why then other is slower?
I have a stored procedure that is executed via a sql script task that returns a full result set. I map this result set to a variable or object type. Is there a way to use this variable as a data source in a subsequent data flow task?
I would like to know what happens during the different phases when executing a data flow task. I noticed that there are the validation, prepare for execute, pre-execute, execute, post-execute, and cleanup phases.
We all know that the execute phase is the actual execution of the desired data flow (source to destination) but I was wondering what the other phases do. Knowing what happens during those phases will help me optimize the whole execution. 1 question raised by someone here is "what is the difference between the Prepare for Execute phase and the Pre-Execute phase? and what does the validation phase do?
I'm trying to get a record count out of a databse using OLE DB Source and row count tasks but keep getting an error. I set up a variable as int32 and select the variable name in the row count task and when I go to the Input Columns tab to select a field to count, it gives me this error:
Error at Data Flow Task[Row Count[505]]: The component "Row Count" (505) has forbidden the requested use of the input column with lineage ID 32.
I have a SSIS (CTP June 2005) package with several data flow tasks. One data flow has 2 OLEDB data sources which are then unioned together, followed by a conditional split, then a derived column transformation, which feeds into an OLEDB destination. When I run the package, this particular data flow seems to run fine and then just stops. There are no errors and the records counts don't move. I've used data viewers to look at the data and it seems fine. I've switched the OLEDB destination with a flat file and execution runs fine, then switched back to OLEDB and it hangs again (over and over). There's nothing unusual about the OLEDB destination, and all the other OLEDB destinations work fine. It also seems to hang on the same destination row number count, but again that row has been verified as valid. In fact, I dropped the DB table and recreated it with no constraints and all fields nullable, but the problem persists. Help?
i got a foreach loop that has about 20 data flow tasks(same database connections but different extractions) but i notice that when i execute the project it only runs 4 data flow tasks at a time.
i know that there is an option for each data flow to set the "Engine Threads", but is there a way to set the thereads in a foreach loop or for the whole project so it will execute all data flow tasks in one go for each loop.
Has anyone come up/determined a generic way to capture and log indicative information within a data flow in SSIS - e.g., a number of rows selected from the source, transformed, rejected, loaded, various timestamps around these events, etc.? I am trying to avoid having to build a custom solution for each of the packages that I will have (of which there will be dozens). Ideally, I'd like to have some sort of a generic component (such as a custom transformation) that will hide the implementation details and provide a generic interface to the package.
It is not too difficult to achieve something similar on the control flow level, but once you get into data flows things get complicated.
I created a package with SQL 2005. The package gets the Access DB and then inserts it into SQL Server.
If I open the package in .NET, I can see the SQL Task and Data Flow Task. The SQL Task has a property sqlstatementsource, which has the necxessary SQL code to create the tables.
How can I tell the SQL Task to recompile the SQL code if I give it another DB name, because the tables differ and don't map in the Data Flow Task
I have a table which has been loaded from various source feeds. The SourceId relates to the source name and the SourceCompanyId is the sources primary key for the company. I am basically trying to create one row with all the SourceCompanyIds in my column headers. What data flow tasks would be necessary in SSIS?
I want to export data from SQL Server2005 to an Excel spreadsheet thru "Data Flow Task". I am using OLE DB for SQL Server for the source connection and a Connection To Excel as my destination source. The Excel spreadsheet (2003) exists and has the first row with column names. I don't have any warnings before trying to execute.
While executing the tasks, I got the error Error: 0xC0202025 at Data Flow Task, Excel Destination [427]: Cannot create an OLE DB accessor. Verify that the column metadata is valid. Error: 0xC004701A at Data Flow Task, DTS.Pipeline: component "Excel Destination" (427) failed the pre-execute phase and returned error code 0xC0202025.
After analysing I found in the DataFlow --> Excel destination --> Advanced Editor for Excel Destination, the default data type for txtRemarks shows as "Unicode string [DT_WSTR]". But this is supposed to be "Unicode text stream [DT_NTEXT]". Even if I change the data type in the design time, It doesn't accept.
I need to call a stored procedure to insert data into a table in SQL Server from SSIS data flow task. I am currently trying to use OLe Db Destination, but I am not sure how to map inputs to OLE DB Destination to my stored procedure insert. Thanks
I am new to SSIS. I need some help in designing the below dataflow task.
-- Teacher creates several tasks and each task is assigned to multiple students -- The teacher table contains contains all the tasks created a every teacher use ods go create table teacher ( yr int, tid int, tname varchar(20), taskid int
)
insert into teacher values(2007,101,'suraj','task1') insert into teacher values(2007,101,'suraj','task2') insert into teacher values(2007,102,'bharat','task3')
insert into teacher values(2007,103,'paul','task4') insert into teacher values(2007,103,'paul','task5') insert into teacher values(2007,103,'paul','task6')
-- Teacher "suraj" has created 2 tasks -- Teacher "bharat" has created 1 task
select * from ods..teacher yr tid tname taskid ============================ 2007 101 suraj 1111 2007 101 suraj 1122 2007 102 bharat 2222
-- Students table contains studentid(sid),teacherid(i,e tid ) & taskid drop table students
create table students ( yr int, sid varchar(10), tid int, taskid varchar(10) )
truncate table students
insert into students values(2007,'stud1',101,'task1') insert into students values(2007,'stud1',101,'task2')
insert into students values(2007,'stud2',101,'task1') insert into students values(2007,'stud2',101,'task2')
--Note : stud1,stud2 comes under teacher with tid "101"
insert into students values(2007,'stud3',102,'task3')
-- Note : stud3 and stud4 comes under teacher with tid "102"
insert into students values(2007,'stud4',103,'task4') insert into students values(2007,'stud4',103,'task5') insert into students values(2007,'stud4',103,'task6')
insert into students values(2007,'stud5',103,'task4')
select * from students yr sid tid taskid ---------------------------- 2007 stud1 101 task1 2007 stud1 101 task2
Now in my target table i need to load the data in a such a way that
use targetdb go drop table trg go
create table trg ( yr int, -- data should load from teacher.yr tid int, taskid int(20), cnt int
)
Mapping in target column and value to be loaded ================================================== yr -- teacher.yr tid -- teacher.id taskid -- this need to start a new sequence of numbers starting from 1 for each teacher and dont want the task id to be copied as it is. cntofstudents -- need to count no of students from "students" table for a given teacher and for his assignment
For example for teacherid "101" and taskid "task1" there are 2 students again for the same teacher "101" and taskid "task2" there are 2 students
For teacher "102" and taskid "task3" there is only 1 student
Similary for teacher "103"
Relation ========
Teacher table | Students Table yr | yr tid | tid
After i run the ETL the data should look as follows :
insert into trg values(2007,101,1,2) insert into trg values(2007,101,2,2)
insert into trg values(2007,102,1,1)
insert into trg values(2007,103,1,2) -- task4 is created by teacher "103" and assigned to 2 students stud4 and stud5 insert into trg values(2007,103,2,1) -- task5 is created by teacher "103" and assigned to 1 student i.e stud4 insert into trg values(2007,103,3,1) -- task6 is created by teacher "103" and assigned to 1 student i.e stud5
Note : If u observer the values in 3rd column of the trg table, instead of directly mapping the taskid we need to generate a separate sequence for every teacher.
BottomLine : for each and every task created by each teacher there should be a unique record along with the count of students in "STUDENTS" table
Can anyone help me out in designing the Data Flow task for this Functionality.
Hi there. I'm trying to learn SSIS, please, help me. I have 2 questions:
1) There are 2 databases on 2 different servers. I need to get data from Table1(database1) and put it to Table2(database2). But I have to insert rows, which ID is not exists in Table2. How Can I do necessary filter?
2) In the OLE DB DataSource Component I have used SQL Command(it's simplified):
declare @TmpTable TABLE (WorkCode int not null);
INSERT INTO @TmpTable (WorkCode) select WorkCode from Table1
SELECT WorkCode FROM @TmpTable
SSIS Package works without any exception. But there is no any inserted record in destination table. If I try similar query without temporary table - it works good. Why?
I have SQL Server 2005 Express edition on my machine. On an SSIS project in BIDS, when i drag a "Data Flow Task" to the package it returns the following error:
The designer could not be initialized. (Microsoft.DataTransformationServices.Design)
Does this has anything to do with the fact that i don't have SSIS installed on my machine?
I thought that SSIS was only needed (on my machine) for the runtime, just to run the packages. To create and edit the pachages i need to install SSIS on my machine too? this doesn't makes sense, maybe it's another problem.
I am having problems with the Data Flow task. It does not even show up in the list of items to drop into the SSIS project.
If I go to the Data Flow tab and hit create, I get the follow error. I have tried repairing and reinstalling, but nothing seems to clear up the error. Without rebuilding my machine, is there anyone who knows how to get the Data Flow Task reinstalled properly?
Thanks
Wayne

I have a simple data flow task setup... 2 ADO.NET connection managers, each referencing a DSN pointed to a Unidata database. 2 DataReader sources, each using a single ADO.NET connection managers, running a simple SELECT statement from a table. I have a Union All transform setup to merge the data and write to a OLE DB Destination (SQL05 database)
When I run the package, each source will validate, but only one will execute. The other source will do nothing. The data source will be colored yellow, and will just sit there. The package will just sit, almost like it is waiting for input.
This behavior is not consistent, however. It varies which data source will hang, pretty much 50-50. About 25% of the time, both sources will execute, and all rows will be written to the destination.
I have a Windows XP X64 machine with SQL 2005 Developer and VS 2005 Team Edition for Architects on it. For the most part it appears that all normal VS and SQL functions are working properly with the exception of SSIS. If I open the developer studio and drag a Data Flow Task onto the design surface I get the message below. I have tried doing an unistall and reinstall of Integration Services as well as a repair on VS 2005 with no success. I've searched the web and newsgroups and can't find any mention of the problem I'm having. Any help greatly appreciated.
I wanna know if we can have more than one "OLEDB Destination" within a Data Flow Task, I want to use the same data flow and write to two different tables in a database with some changes. If we cannot do this within the same data flow what is the best way to do this.
How can I debug data flow task. From this article (http://www.databasejournal.com/features/mssql/article.php/3567961) and this video (http://www.jumpstarttv.com/Media.aspx?vid=3) I found that when we are executing the task, the data count will be shown along with color coded task but when I debug the package, no count is shown. I have SQL and source and flat file as destination. There is nothing stored in the destination file but the sql script returns the data.
I was working all day making changes to my 3MB package. I was adding a large number of transforms that were copied-and-pasted from elsewhere in the same data flow task.
All was going well. I even took the time to have SSIS lay out the task again (1/2 hour). Suddenly I started receiving some strange errors:
After the layout, I noticed two stray components 'way off in the upper right corner. I found that one of them had a duplicate name to a component which had been added hours ago. Even after deleting it, I got "duplicate name" errors.
I copied three components in one selection, and when I tried to paste them, got the error "can't initialize component on paste". I tried them one at a time, but got the same error.
I got errors about COM failures due to marshalling to another thread I then exited Visual Studio and started it again. To my great surprise, the data flow task I was working on was still there, but was completely empty.
Comparing what I'm left with to my last version in source control, I find that the entire pipeline element is missing from the DTS: ObjectData element!
I'm developing a real love/hate relationship with SSIS. It varies from one day to the next. Guess what kind of day this is!

I'm creating an SSIS package, a Data Flow Task. I have used OLEDB Source connected to a SQL Server Destination. Now in my OLEDB Source, I have this SQL statement
SELECT FirstName, LastName, Age FROM Employees WHERE (Age > 10) AND (Age < 95)
But what I want is to have the last name and first name concatenated and in proper case(capitalize first letter of the firstname and surname). I also want to TRIM or remove the blank spaces of the field in my SQL statement. How I be able to do this?
I tried using proper(), trim() and ucase() like in MSAccess but no success.
I have a fairly simple data flow task that loads data from one table (OLE DB Source) into another table (OLE DB Destination). The data type for one of the pairs of columns is nVarChar(120) and it contains version information that looks like a decimal. When I run the export, the destination has a trailing zero added after the decimal point as if it were a numeric column which invalidates our comparisons (string 1.0 is not the same as string 1.00). There is no cast or convert done to this column, it is a straight copy. Any ideas what could be causing this or how to fix?
