Inside a data flow task, i have a oledb source and destination. In my situation, I need to pull data from a table in the source, but also hard code some columns myself, which means my source is a blend of data from table, hard coded data, which will then have to be mapped to columns in oledb destination. Does anyone which option to choose in the oledb source dropdown for the data access mode. Keep in mind, i do need to run a a select query, as well as get data from a table. Is it possible to use multiple oledb sources and connect to one destination, because that is really what intend to do here. I am not sure how it will work, or even if its possible. Basically my source access mode needs to be a blend of sql command and table columns, how would that be implemented? Any help or advice is appreciated.
I have a package that does simple exporting from an excel sheet to a table. I used a Dataflow task with Excel Source and OLEDB Destination Components. And i created Package configurations for Source and Destination Components. After than when i execute the package i get the following error.

We have a single generic SSIS package that is used to import several hundred iSeries tables into SQL. I am not looking to rewrite the process. But I am looking for ways to improve performance.
I have tried retain same connection, maximum insert commit size, lock table (tablock), removed some large columns, played with the log file location and size, and now I am working to tweak the defaultbuffermaxrows.
To describe the data flow task - there are six data flows tasks (dft) working at the same time. Each dtf has their own list of iSeries tables and columns and the corresponding generic SQL table names. Each dtf determines their list of tables based on the number of columns to import. So there is dft30 (iSeries table has 1-30 columns to import), dtf60 (iSeries table has 31-60 columns to import), etc. The destination SQL tables are generically called Staging30, Staging60, etc. Each column in the generic Staging tables are varchar(100). The dtfs are comprised of an OLE DB Source and an OLE DB Destination.
The OLE DB Source uses a SQL Command from Variable to build a SELECT statement. The OLE DB Source uses a connection manager that uses an IBM iAccess IBMDA400 provider. The SQL Command ends up looking like this for the dtf30. This specific example is importing from the iSeries table TDACLR and it only has two columns so it will be copied to the Staging30 table.
select TCREAS AS C1,TCDESC AS C2,0 AS C3,0 AS C4,0 AS C5,0 AS C6,0 AS C7,0 AS C8,0 AS C9,0 AS C10,0 AS C11,0 AS C12,0 AS C13,0 AS C14,0 AS C15,0 AS C16,0 AS C17,0 AS C18,0 AS C19,0 AS C20,0 AS C21,0 AS C22,0 AS C23,0 AS C24,0 AS C25,0 AS C26,0 AS C27,0 AS C28,0 AS C29,0 AS C30,''TDACLR'' AS T0 from Store01.TDACLR
The OLD DB Source variable value looks like the following, but I am not showing the full 30 columns
select cast(0 AS varchar(100)) AS C1,cast(0 AS varchar(100)) AS C2,cast(0 AS varchar(100)) AS C3,cast(0 AS varchar(100)) AS C4,cast(0 AS varchar(100)) AS C5, ... cast(0 AS varchar(100)) AS C30.
The OLE DB Destination uses OpenRowSet Using FastLoad From Variable. The insert into Staging30 ends up looking like this.
Of course we then copy and transform the Staging30 data to the SQL table that equals T0.
But back to defaultbuffermaxrows. Previously the dtfs had default values of 10000 for DefaultBufferMaxRows and 10485760 for DefaultBufferSize. I added a SQL task to SUM the iSeries column sizes, TCREAS and TCDESC in this example, and set the DefaultBufferMaxRows by dividing the SUM of the columns max_length into 10485760. But I did not see a performance improvement. Do you think that redefining the columns as varchar(100) for the insert is significant? Should I possibly SUM the actual number of columns (2) as 2x100 or SUM the 30x100?
I have a simple data flow task, composed of only an OLEDB Source, a Conditional Split, and two Execute SQL statements (both insert statements, one after the other). When I run my package in Visual Studio for debugging, I noticed that after executing around ~9800 in the first and another ~9800 records in the second insert statements, the OLEDB Source will take around 3 or 4 minutes to fetch another set of ~9800 records. I have set the DefaultBufferMaxRows property of the Data Flow to 10000. My query to retrieve those 700,000 records runs for about 2-3 mins to finish (which I think should be decent enough). Is this an expected behavior of SSIS? The expected number of records to be retrieved is 700,000, and it takes forever to finish the transfer of these records. Please help
I am trying to execute a SP like below in OLEDB source in data flow... and this statement include the insert stament ( row by row transaction).. I would like to creat an error hadling logic so that if the trasaction fail to insert the row then ignore that particular row then, move to the next row without stopping the whole process.. how can i do this?
I need to see inside a SSIS 2012 project a new SSIS installed component, but in the SSDT 2010 I cannot see the SSIS Data Flow Items tab for adding data source/data destination respect to the choose toolbox items pane.
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 got an error when i do an OLE db Source pointing to an sql 2000 database and executing a sql query inside the OLE Source. The ole source will point to an OLE DB destination which is an sql 2005 database.

How do I retrieve the connections (connection managers) collections from Custom Data Flow destination? ComponentMetadata.RuntimeConnectionCollection is empty. I would like to be able to access all the connections defined in the package from the custom data flow task.
I came across code in which it was possible to access the Connections collection using the IDtsConnectionService for custom task (destination). The custom task has access to serviceProvider, whcih can be used to get access to the IDtsConnectionService interface but not the custom data flow task.

In many DTS packages I have used parameterised queries for incremental loads from Oracle database sources using the Microsoft ODBC Driver for Oracle.
Now I want to migrate these packages to SSIS, but the OLE DB connection for Oracle does not support parameters.
I cannot use the "SQL command from variable" data access mode because of the 4000 character limitation on the length of string variables and expressions.
An SSIS package to transfer data from a DB instance on SQL Server 2005 to SQL Server 2000 is extremely slow. The package uses an OLEDB Source to OLEDB Destination for data transfer which is basically one table from sql server 2005 to sql server 2000. The job takes 5 minutes to transfer about 400 rows at night when there is very little activity on the server. During the day the job almost always times out.
On SQL Server 200 instances the job ran in minutes in the old 2000 package.
Is there an alternative to this. Tranfer Objects task does not work as there is apparently a defect according to Microsoft. Please let me know if there is any other option other than using a Execute 2000 package task or using an ActiveX Script to read records from one source and to insert them into the destination source, which I am not certain how long it might take and how viable will that be?
How do i use the foreach loop container and pass each file found according to a specified pattern to a Flat File Source in a Data Flow Task Object so i can operate on each file found in the foreach loop object instead of having to specify a static file name
I'm importing a large csv file two different ways - one with Bulk Import Task and the other way with the Data Flow Task (flat file source -> OLE DB destination).
With the Bulk Import Task I'm putting all the csv rows in one column. With the Data Flow Task I'm mapping each csv value to it's own column in the SQL table.
I used two different flat file sources and got the following:
I am using execute sql task to run a stored procedure in oracle database which returns a resultset. This works. Now I need to send the ouput to a destination table in a sql database. Should I use for each loop to pick the resultset and insert it into the destination one by one (which I dont think is a great idea) or is there a better way to accomplish this task (in data flow task) ?
When I use dataflow task instead of execute sql task, the main issue is I am not able to see the output columns when I execute an oracle stored procedure, but when I see the preview I can see the resultset . But I can see the output columns for a sql server stored procedure.
I have a table that I'm loading as part of a control flow that in turn is copied to a target table by using a data flow task. I am doing this because a different set of fields may be used from the source entry to create the target entry based on a field in the source table. That same field may indicate that multiple entries need to be created in the target table from one source table entry for which I use a multi-cast transformation.
The problem I'm having is that no matter how many entries there are in the source table, the OLE DB Source during execution only shows 7,532 entries being taken from the source table. If there are less than 7,532 entries in the source table, everything processes fine. More than 7,532 and the data flow task only takes 7,532 and then seems to hang. It also seems as though only one path of the multi-cast transformation is taken when the conditional split directs a source entry down that path.
Seems like a strange problem I know, but any insight anyone could provide is appreciated. Thanks.
I have a strange problem, which I never encountered earlier, I have a data flow which has one source and multiple destinations, I am also using multicast and derived column transformations too, however when I run the package (either from cmd line or designer) the data flow task hangs when it comes to inserting data into the target tables. and it keeps waiting forever. Initialy I thought it was my data set , however if with very few records the problem persists. I have also tried removing the table lock from the destination , increasing the rows per batch to 10000 and commit size to 10000 but to no change. I am using the fast load option within my destination. When I run sp_who2 on my Management Studio I see that the status of all the processes is sleeping and the command is "awaiting command" , any help appreciated.
Copy a full directory from source to destination (Done)
then for each file on the destination directory,it must process that file and insert rows on the table.
So I created a foreach loop, and created a varriable aclled CURRENTFILENAME, and assigned it into the foreachloop to index 0.
Inside the foreachloop I created a dataflow task, in the dataflow task I dragged a flat file source and an oledb destination, but I noticed that the flat file source requires flat file manager, and the flat file manager requires a unique FILE NAME. I cant put this c:copia*.txt.
I took a loot at flat file source properties and it has associated the flat file manager, but I can not assign the filename to the variable from the foreach.
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 have a simple Control Flow setup that checks to see if a particular table exists. If the table does not exists, the table is created in an alternate path, if it does exist, the table is truncated before moving to a file import Data Flow that uses an OLE DB Destination to output the imported data.
My problem is, that I get OLE DB package errors if the table the OLE DB Destination Container references does not exist when I load the package.
How can I over come this issue? I need to be able to dynamically create the table in an earlier step, then use that table to import data into in a later step in the workflow.
Is there a switch I can use to turn off checking in the OLE DB Destination Container so that it will allow me to hook up the table creation step?
Seems like this would be a common task...
Steps:
1. Execute SQL Task to see if the required table exists 2. Use expresions to test a variable to check the results of step 1 3. If table exists, truncate the table and reload it from file in Data Flow using OLE DB Destination 4. If table does not exist, 1st create it, then follow the normal Data Flow
I have set up a new connection as a connection from data source, but I cannot see how to use this connection to create my Data Flow Source. I have tried using an OLE DB connection, but this is painfully slow! The process of loading 10,000 rows takes 14 - 15 minutes. The same process in Access using SQL on a linked table via DSN takes 45 seconds.
Have I missed something in my set up of the OLE DB source / connection? Will a DSN source be faster?
I can't seem to find a way to make the Data Flow Destination in a Business Intelligence Visual Studion Project output an MDB file for Microsoft Access.
i am performing the ETL on the as400 db2 database using ms- dts,ssis.
i have built the connection b/w as400 and source to extract data from as400 to staging means in dataflow . when i have built the oledb connction for loading data to destination as oledb destination.then it will connct successfully to the db2 as destination but when execute the task then it not load data , and give provider error.
I am getting the following error running a data flow that splits the input data into multiple streams and writes the results of each stream to the same destination table:
"This operation conflicts with another pending operation on this transaction. The operation failed."
The flow starts with a single source table with one row per student and multiple scores for that student. It does a few lookups and then splits the stream (using Multicast) in several layers, ultimately generating 25 destinations (one for each score to be recorded), all going to the same table (like a fact table). This all is running under a transaction at the package level, which is distributed to a separate machine.
Apparently, I cannot have all of these streams inserting data into the same table at one time. I don't understand why not. In an OLTP system, many transactions are inserting records into the same table at once. Why can't I do that within the same transaction?
I suppose I can use a UnionAll to join them back together before writing to a single destination, but that seems like an unnecessary waste and clutters the flow. Can anyone offer a different solution or a reason why this fails in the first place?
Is there a default destination component used when a new data flow is created? The reason I ask is simply curiosity. I have an xml file with 2 pieces of data: item A and item B. A should simply get copied out of the file. B should undergo a quick transform. I set up an XML source such that two columns are mapped correctly to the XML source data of A and B. I set up my data transform task as well. So, if I leave those two components on the .dtsx page with no other components, then will there be a default data flow destination already created? ...OR, do you always have to have a destination component?
I have a series of data flow tasks that I want to output to a temp table. I've set the data source for RetainSameConnection and the Data Flows are DelayValidation. The OLE DB data source inside the Data Flow works fine, but the data destinations don't offer a # or ## as a target. I've tried every destination that sounds logical, without success.
I have a data flow that reads multiple rows from a table and then inserts to another table for each row. I use an ole destination for my inserts. However, after that insert I need to do other table inserts and I can't figure out how to continue the data flow with the fields in the pipeline. Out of the destination is only the Error flow - Is there a way to do this ?
I would like to extact data from a source system even if it has errors. Then I can transform it and handle the errors in the appropriate manner. Are there any loosely-typed Data Flow Destinations?
