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
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 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?
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?
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 developed an SSIS package doing a nightly load into a data warehouse. We have an 8 hour loading window - currently the package takes 16 hours to complete.
I isolated the problem to a Data Flow task where +-35% of the time is spent. This task is pretty straight forward:
- OLE DB source, reading +- 800,000 rows from a SQL server database
- 13 Lookups in sequence, to get surrogate keys from dimension tables. Lookups are all on GUIDS.
- An aggregation
- OLEDB target, fact table in a SQL server database.
It seems unreasonable for the this task to take over 5 hours. It spends the majority of time on the lookups - not so much at target, source and aggregation.
Any comments and advice will be greatly appreciated.
Thanks.

A little background first. I have a header table and a detail table in my staging area/ods. I need to join them together to flatten them out for load. The Detail Table is pretty deep - approx 100 million rows.
If I use the setting (table or view) and set the table name (say, the detail table), the package starts up nicely. But if I switch the OLE DB Source to using a SQL Statement and then join the tables in the SQL, then the Pre-Execute phase of the package takes a VERY long time. I have waited as long as 30 minutes for this phase to complete, but it never finished.
Another twist...If I take the join select statement out of the OLEDB Source and put it in a view on the server, then swith the OLE DB Source to look at the view using the (table or view) mode, then the package gets through the Pre-Execute phase just fine.
Can someone go into detail as to what the Pre-Execute phase does and why a deep table might make it take a long time? I know already that the pre-execute phase caches the lookups, but not much else.
I have developed some packages to load data into "Fact" tables in the data warehouse. Some packages are OK, other ones not. What is the problem?: some packages load fact tables with lots of "Lookup - Data Flow Transformation" into the "data flow task" (lookup against dimension tables) but they are very very slow, too much slow to be choosen as a solution.
Do you have any other solutions to avoid using "Lookup - Data Flow Transformation"? Any other solution (SSIS, TSQL and so on....) is welcome to speed up the Fact table loading process.
I'm importing from a SQL table that has data fields typed as numeric(18,2) and the OLEDB data source component converts the data to integers (as viewed in the data viewer). I've preceeded the column names with (DT_NUMERIC,18,2) with no results. When the data gets saved to a table with the field typed as money, it appends .00. The truncation of pennies (decimal) results in the diminution of the daily results as much as $1,000. How do I pass the pennies through the OLEDB data source component? Is this truncation by default,or is there something I'm missing in the configuration? thanks.
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 been using a recordset destination in a data flow where I need to perform some complex manipulation on a dataset, including combining some information from a web service and updating records that already exist, vs. inserting them.
I have a script task that modifies the dataset as needed, and then saves it back to the variable it came from.
However, when it comes time to write the data to the database, I couldn't find an appropriate tool - there's no "recordset source" object in the data flow task, and use of a "for each" loop with a sql call to a stored proc takes 20 minutes for a few thousand rows.
The best way I could find around this was as follows:
Call the .NET ".GetXML" method on the dataset and put the resulting XML data into a string variable Generate an XSD for that XML (it comes out like <NewDataSet><Table1>...) Use an XML source in the data flow task.This works, and the same data insert that took 20 minutes via the loop / stored procs now takes under 10 seconds.
It seems horribly inefficient to have to do this - there should be a way to just dump my dataset back into a table natively without all that extra stuff.
Another requirement has cropped up with regard to picking up connection settings for data sources from an external File.
My source and target are both in SQL Server. What i need is that if my source or target changes I should just change my external file and same should reflect in my package.
How can I accomplish it? Please suggest some solution.
Hi All, In one of my SSIS Interface I have to Merge data from a Oledb source and a Flat file source.But after I read from the flat file I have do a basic validation of the file for the length of header,detail and trailer records and then process further.The above Validation I am doing within Script Component.If the validation fails the flow should pass out of the DataFlowTask without Initailsing the Oledb source.
But the problem is i am not able to connect anything to the Oledb source,i.e Oledb source is not taking any incoming Pointers. Earlier I had done the same Validation in Control Flow Task,but then the interface was reading the same file twice,once in the Control Flow Task and then again in the DataFlowTask.Which i should avoid now.
I hope many of you could have come across such a problem. Any help on this will be appreciated.
I am new to SSIS programming, so bear with me if my question seems naive to you gurus. I have a situation that needs to set the data source for a data flow from external .NET application ('external' means that the application will run on different process than the SSIS). I am trying to set the data source on which the data flow works from my C# application in a DataSet format. Ideal solution is not to save the DataSet to any file on harddisk (I know that will work, but has the overhead of writing, reading and managing the temp file). What I want to achive is that the business logic of picking data for SSIS Data Flow to process is controlled inside my C# application, the Data Flow just does what it does best - Transformation. Have any of you successfully done this before?. Thanks!
i have a package in ssis that needs to deliver data from outside servers with odbc connection. i have desined the package with dataflow object that includes inside a datareader source. the data reader source connect via ado.net odbc connection to the ouside servers and makes a query like: select * from x where y=? and then i pass the data to my sql server. my question is like the following:
how do i config the datasource reader or the dataflow so it will recognize an input value to my above query? i.e for example:
select * from x where y=5 (5 is a global variable that i have inside the package). i did not see anywhere where can i do it.
Hello, I have 2 table, "table1" is the source one and the other one "table2" is the destination. Columns in Table1 and in Table2 are nvarchar(max). Data loaded from table1 is performed by SSIS OLEDB data flow source, I have found out that opening "Data flow Path Editor" in the Metadata, columns are as: DT_WSTR with lenght 4000.
First question: Why SSIS limit the column to 4000.
Then I get some error for this issue, with the error: input column "col1" (xxxx) and reference column named (coln) have incompatible data type.
As written before both columns are string, the problem is that SSIS limit the lenght of the string to 4000.
We're trying to read DBASE IV files as a source, but can't find any providers for that format. Will these be included in the final release? Is there another way? DBASE has always been supported, so it's kinda stranged.
I'm wondering if it is possible to create a flat file source on the fly while bypassing the following step:
On the Connection Managers page, add or create the Flat File connection manager, using a descriptive name such as MyFlatFileSrcConnectionManager. Then close the Script Transformation Editor.
I want to create the connection totally in script, yet i'm having a hard time proving this out...does anybody have any experience with this?
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.

I'm creating a SSIS in the designer view of SQL Server BI Dev. Studio (SQL Server 2005)

I am able to use a custom script task to receive a MSMQ package and save the package contents to a flat file.
I can also use the bulk load task to push the flat file contents into a SQL table.
However, I would like to save the package contents to a variable (done, it works), and then pass that string variable to a data flow task for SQL upload. In other words, I don't see any reason to persist the msmq package contents to disk.
My question is: Which data flow source can I use that will accept a string variable? The string variable will then need to be processed with bulk load or an execute sql task.
Btw, the content of the string variable is a csv style string:
In DTS 2000 I had a situation where I had a text file as input source and text file as output source. On migrating the package to 2005 it puts a wrapper around it which executes it as a 2000 package, the rest of the tasks are neatly converted to 2005 style tasks. I presume this to mean that this will not be supported through to the next version, and there is no direct equivalent in 2005.
My question is how do I import a non-flat file source which has different numbers of columns per line. I did ,somehow, manage to do this with 2000 but cannot seem to get anywhere with 2005.
The flat file source seems to be expecting a common number of columns and just can't seem to cope with no column delimiters on some lines. If anybody knows different I would be glad to hear about it.
Raw data is not helpful to me as only works with a specific raw type (apparently)
Went onto Bulk Insert Task but got this message
[Bulk Insert Task] Error: An error occurred with the following error message: "Cannot fetch a row from OLE DB provider "BULK" for linked server "(null)".The OLE DB provider "BULK" for linked server "(null)" reported an error. The provider did not give any information about the error.Bulk load: An unexpected end of file was encountered in the data file.".
Have already browsed with this on web but only find comments about changing timeout setting.
Can find timeout settings in DataFlow source and DataFlow destinations but not in Bulk Insert Task.
As you can see this is a long and protracted question.
If the answer is simple I apologise if not blame Microsoft. Other than that have found SSIS has some nice improvements, apart from the odd vague error message I keep coming across.
Okay, this should be really simple but I don't get it. How do I use an ODBC data source in an SSIS data flow task? When I look at Data Flow Sources I see the following options:
Pointer
DataReader Source
Excel Source
Flat File Source
OLE DB Source
Raw File Source
XML Source
Which one do I use if I need to get the data from a connection manager that is ODBC based? The IBM OLEDB driver for the AS400 doesn't work correctly so I HAVE to use an ODBC driver to connect to an AS400 data source.
I am working to archive some old data from a data warehouse using SQL server and SSIS. The data will be read and denormalized, then shipped out to a delimited text file.
The rowcount of the incoming data is significant, call it 10M+ rows per unit of work (one text file).
There are development advantages of using a stored proc for the data source - mainly ease of changing the denormalization logic as required. Wondering if there are performance advantages of an embeded query for the data source instead?
It was mentioned by one developer that when using a stored procedure, the output stream from the proc and subsequent SSIS steps cannot start until the full procedure processing is complete; i.e. the proc churns out its' result set in one big chunk.
He hinted that an embedded query does not have this same effect, but I am not sure that is accurate.
I am try to transfer some tables data from one database server into another database server. I create a package in SSIS, and I use a variable to pass each table name. In Data flow, I use a OLEDB Source, but I cannot set the Data access mode to Table name or view name variable. Ever time, I will get this following error info "===================================
Error at Data Flow Task [OLE DB Source [31]]: A destination table name has not been provided.

Some one can tell me what is the reason, or give me some examples.
At our business we are getting a lot of PDF documents that are being hand keyed into a database. Has anyone heard ior know of a SSIS Data Flow Source component that I coud use to read thos documents into a data stream (?) and process?
Hi, Quick question on how SSIS handles queries from Data Source in a Data Flow. I noticed that when I run a particular query from Query Analyzer it takes forever. But, when I run the same query in SSIS data source in a data flow. The query results are immediate.
The query plan is already cached in SQL.
Is this just something which I am seeing incorrect or is there some bit of optimization in there in SSIS. As per my understanding SSIS does not optimize the source query.
