Built In Limit Or Setting That Limits The Number Of Rows From An OLE DB Source Table In A Data Flow Task?
Feb 16, 2007
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 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?
Is there a limit of how many rows a table can have in SQL compact Edition? I didn't find anything in the documentation, but I get regularly a funny error message "Expression evaluation caused an overflow. [ Name of function (if known) = ]" when I try to create record number 32768 (is equal to 2 to the power of 15).
I am facing an issue that Data flow task failing after loading 29000 rows out of 2lakhs rows.
I am loading data from .csv file to OLE DB Destination.
This data flow task is placed inside For each loop container.
is this issue because of any performance issue in SSIS packages such as buffer size.
find the error below:
DFT Load Data from FlatFile:Error: The conditional operation failed. DFT Load Data from FlatFile:Error: SSIS Error Code DTS_E_INDUCEDTRANSFORMFAILUREONERROR.Â
The "DER Add Calc Columns" failed because error code 0xC0049063 occurred, and the error row disposition on "DER Add Calc Columns.Outputs[Derived Column Output].Columns[M_VALUE_NUM]" specifies failure on error. An error occurred on the specified object of the specified component. There may be error messages posted before this with more information about the failure.

The identified component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running. There may be error messages posted before this with more information about the failure.
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 executed a packege so that it loads data from from the excel file to the SQL Server Server database. When I execute it, it prompts the following error message and 1 warning The excel file has three colums, Week, Item and Value

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.
All, I'm having an issue with the Flat File Data Flow Source returning only a limited set of the rows that are in the flat file. Basically, I connect to the flat file fine, it goes to retrieve the data (tab delimited file) and only returns 190 of 392 rows. Is there a limitation on the # of rows this data flow source can retrieve or something? I've look all through the settings and properties of the task as well as the connection manager and nothing is obvious as to what is causing this. Hopefully someone ou tthere has run into this before and can help me retrieve all rows. Thanks in advance!
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.

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'm using the Data Flow Task to load data from a flat file into a SQL table and I'm missing rows. And there doesn't see to be any consistent or obvious reason why.
When I use the Bulk Insert Task I import the correct number of rows from the flat file. But when I use the Data Flow task and use a Flat File Source connected to a OLE DB Destination I get about 1/3 the right number of rows. So looking at these loaded tables at the same time I notice that the Data Flow Task method just skips rows sometimes.
I built a package to transform data from flatfile into temp table. Then execute a stored procedure to tranform from the temp table into the real table. Since the real table have primary keys so it goes failed when there're duplicate rows from temp table. I let the temp table has no primary key. If I had to check the temp table for duplicate rows it would be using cursor through the data and the package will get slow. Is there task in SSIS to identify the duplicate data and eliminate it without using cursor ? Thanks in advance,
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 Staging30Â 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?
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 database hosted by GoDaddy. Recently they made some changes to the interface and upgraded to SQL Server 2008. One or the other has made it impossible to access my data in one table.
The table is quite large in terms of the numbers of elements. Each row describes a dog and all the elements are components of the description. There are (I would guess) more than 50 elements all together.
When I try to search the database, the query form goes beyond the top and bottom of the page. I can scroll the database but the search tool (which lies atop the data) does not scroll. The result is that I can't activate the search.
I've tried about 10 machines. All with IE6 display this fault. Machines with IE7 do not. I've tried various screen resolutions on the machines with IE6. That doesn't help.
I've checked other tables in the database. No problem.
In short, there's nothing I can do. I can't edit my data and GoDaddy says, "Tough."
Is there a limit on the number of columns (elements) in a table in SQL Server 2008?
I guess this should be rather simple to answer but i just don't get how to do this. I just want to import some data from an Access mdb file into a SQL Server 2005 Database.
As I dont want to create all tables in Sql Server 2005 beforehand i'd like to create them out of my SSIS Package. Therefore i use the 'Execute SQL Task' in the control flow before stepping into the dataflow where only a oledb-source and an oledb-destination exist...
VERY simple... My problem is, that i can't select the table from the selectionlist in the oledb-destination because it does not exist before executing the package...
If i create the table by hand just to be able to select it, that does not help. because if everything is set up and then i delete the table (because it will be created by the package anyway) an error occurs before executing the package - in the validation phase:
Package Validation Error: "Invalid object name 'myToBeCreatedTable'".
Can't i create tables on the fly which i use then in my dataflow tasks?
Kind regards,
Wolfgang

Hi, Here's my problem. I have an Area Chart, and I need to plot more than 300,000 records. Problem is RS cannot seem to handle this huge dataset. It would retrieve for 20mins, then after that it will just have an error "Internet Explorer cannot display the webpage". I am not encountering this if I just have a few records to plot. Please help
I have designed a datawarehouse and I have tremendous doubt about SQL 7.0 capabilities. I expect to receive more than 20.000.000 into a single table and to be honest I do not know if I will get a reasonable query-response time. My Server is a Toshiba Lince with a 500 Mhz processor and 256 Mb of RAM memory. My hard disks are IBM ones. Can anybody say me something? Thank you in advance.

I have a data transform from a flat-file to a SQL server database. Some of the flat-file fields have NULL values. The SQL table I'm importing into does not allow NULL values in any field, but each field has a Default value specified.
I need to have it so that if a null value comes across in a field using the data transform, it takes the table default on import. I could of sworn I had this working a few days ago, but I get errors now that state I'm violating table constraints. Has anyone done this before?
I have a data flow task in which there is a OLEDB source, derived column item, and a oledb destination. My source is a SQL command, that returns some values. I have some values, that I define in the derived columns, and set default values under the expression column. My question is, I also have some destination columns which in my OLEDB destination need another SQL command. How would I do that? Can I attach two or more OLEDB sources to one destination? How would I accomplish that? Thanks
Kindly i need support in this issue, i create task flow import from flat file and store in database but i need to save all result for task into specific table
Using SSIS 2012 (within Visual Studio) on Windows 7.
Before allowing my Data Flow task to fire, I'd like to check the target table (OLE DB Destination) for a specific date value in a specific field. I've seen how the Lookup Task is commonly used to check for dupes before inserting, but I'm not able to use that method because the data value I want to search the table for is contained in a Global Variable (let's say "MyVariableDate").Â
Is there any way to check for any records in a target table where Date1 = MyVariableDate (i.e. scanning the entire table for any occurrence of MyVariableDate in the Date1 field)?
Hello everyone, I'm having an issue with dynamically setting the Send Mail task's to field to decent sized recipient list(approx 15 email addys). The strange thing is that this same package works fine if I'm using a list of say 4 email addys. I have double checked everything I can think of....list is seperated by semicolons, each address looks good....and have ran script tasks to check my variables along the path of the package but so far have not found the reason. The error I get is below:
"The specified string is not in the form required for an e-mail address"
Also of note, these addresses are being populated from a table, that is then setting the To string of the send mail task via a seperate variable...that variable being populated from a foreach loop. Again, all of this works fine with a smaller recipient list. Any ideas?
The only thing I can think of right now is to run the send mail task within the foreach loop...but then I'll be sending a seperate email for each address and would like to avoid that if possible.
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 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'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.
