I have a user variable , say max_id, which retrieves the max id from a primary key column of a table.
now in Data Flow Task, I have a Derived Column where I am creating a new column which will have the values max_id + 1 for the first record, then max_id + 2 for the second record of the derived column and so on..
and then I am mapping this derived column with that primary key column of the table, so that the new id's are different than the old ones which are already in the table, so there wont be any primary key violation.
I cannot make that primary key column as an Identity column.
my question is how do I increment this max_id user variable everytime ?
In the derived column transformation editor, I have a Derived column name called FileGroupID. I would like to pass in a value for this column from a variable that I have set earlier in the scope. Can someone let me know, how to write the expression that does that and where do I specifiy that expression. I am thinking its the expression field in the derived column transformation editor. My main question is how to actually write the expression, what is the syntax to pull the variable value? Thanks.
In the data flow task, i have done a group by and now i have a single row.... I want to assign the value in this row to a package variable.... Without using the script component .......Any suggestions ??
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.
Please can anyone tell me if or how I have to cross reference to a user defined variable from a script task in the SQL of a Data Reader Source?
The script task creates a variable for the last Sales Ledger Session. The SQL in the data reader source that updates the DW sales invoice lines file based upon those invoice lines where the session number is greater than the value from the script task.
The SQL command in the custom properties doesn't cross reference back to the variable.
If anyone can help or needs further detail to help please post a resonse.
I'm currently setting variables at the package level with an ExecuteSQL task. This works fine. However, I'm now starting to think about restartability midway through a package. It would be nice to have the variable(s) needed in a data flow set within the data flow so that I only have to restart that task.
Is there a way to do that using an SQL statement as the source of the value in a data flow?
OR, when using checkpoints will it save variable settings so that they are available when the package is restarted? This would make my issue a moot point.
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'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 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
Hi all, By using for each loop container and script task, i am able to pick the file name from a specified folder to a user defined variable. Now i am trying to pass this variable to excel source (using data flow), but i am getting this error : -

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.
How to define a Input variable in a Execute Sql Task?? I've defined a User::Inicio variable which contains 4 as value.
In Parameter Mappins it has been defined. Then, I've gone to General->Sql Statement and allocated the following SQL Statement: UPDATE CARGAPROCESOS SET FECHAULTIMACARGA = [Inicio] or UPDATE CARGAPROCESOS SET FECHAULTIMACARGA = [User::Inicio]
Anyway, I'm stuck, both did not work Thanks in advance for your comments
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
Hello There: I am running a data flow within a ForEach loop wherein I am computing a value called QuotaGap. When it is 0 I do not want any further execution of the loop. I am using a Conditional Transform within this dataflow that writes a record to a table only when the QuotaGap is NOT 0. However, I am unable to terminate the execution of the loop as I am still within the dataflow.
Now, the computation of the gap requires a value from another variable called NetPurchases. I tried using an ExecuteSQL task in the control flow but could not figure out how to pass the value of the variable NetPurchases into the select statement to compute the gap. For example, the select statement would read:
select (QuotaUpperLimit - ?) As QuotaGap from <<tablename>>
I tried setting the parameter as an input as well as an output and it did not work.
Then I tried passing the entire SQL as a string within a variable. This does not work either because in order to compute the math QuotaUpperLimit - NetPurchases, both variables need to be integers but then you cannot concatenate integres together, which is what we need to do to create the SQL.
The other reason I am going through these hoops I guess is that I have not figured out a way to set the value of a variable within a data flow. I compute the value for QuotaGap within the dataflow in a ForEach loop but I have no way to pass this result to a variable called QuotaGap without using an ExecuteSQL task or another ForEach Loop.
I have spent hours on this simple issue and so have given up and looking to the good friends in this forum for help.
If what I have stated is not clear please let me know and I will try to clarify things a bit.
My package sets a variable in an ExecSQL task. This variable is then used as a parameter in a DataFlow task that follows. Normally everything works just fine. However, sometimes if the package fails inbetween the step that sets the variable and the DataFlow, the default value of the variable is stored in the checkpoint file. (It is not failing in the step that sets the variable) When the package is restarted I can see that the variable is not set to the data value in the database, but rather it has its default (design time) value.
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!
