OLEDB Destination Task Hanging
Oct 5, 2007
Hi,
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.
Thanks

Hi
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.

Hi all,
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.
But i got the below error:
Error at Data Flow Task [OLE DB Destination [245]]: the column firstname cannot be processed because more than one code page (936 and 1252) are specified for it.
Error at Data Flow Task [DTS.Pipeline]: "component "OLE DB destination" (245)" failed validation and returned validation status "VS_ISBROKEN".
Error at Data Flow Task [DTS.Pipeline]: One or more component failed validation.
Error at Data Flow TaSK: There were errors during task validation.

OK. I give up and need help. Hopefully it's something minor ...
I have a dataflow which returns email addresses to a recordset.
I pass this recordset into a ForEachLoop configuring the enumerator as (Foreach ADO Enumerator). I also map the email address as a variable with index 0.
I then have a Execute SQL task which receives this email address as a varchar variable (parameter 0) which I then use in my SQL command to limit the rows returned. I have commented out the where clause and returned all rows regardless of email address to try to troubleshoot this problem. In either event, I then use a resultset to store the query result of type object and result name 0.
I then pass this resultset into a script variable to start parsing the sql rows returned as type object. ( I assume this is the correct way to do this from other prior posts ...).
The script appears to throw an exception at the following line. I assume it's because I'm either not passing in the values properly or the query doesn't return anything. However, I am certain the query works as it executes just fine at the command prompt.
Try
ds = CType(Dts.Variables("VP_EMAIL_RESULTS_RS").Value, DataSet)
My intent is to email the query results to each email address with the following type of data by passing the parsed data from the script to a send mail task. Email works fine and sends out messages but the content is empty. I pass the parsed data as string values to the messagesource and define the messagesourcetype as a variable in the mail task.
part number leadtime
x 5
y 9
....
Does anyone have any idea what I might be doing wrong?
thanks

Hi,
On production server, I have two tasks in status "performing completion action" for last couple hours. Ususally these tasks take seconds to finish.
Do you know how can I kill or cancel these tasks? I tried to stop both the jobs couple times but nothing is happening.
There are no locks/blocks on current activity window.
Please give your suggestion.
Thanks.

In my control flow, I have a container which contains an Execute SQL Task, and then upon success, a Data Flow Task. The SQL Task truncates my datamart table. In the data flow task, I execute a stored procedure (through a variable) that populates that same datamart table. I can execute the stored procedure's select statement in Management Studio with no problems in about ten seconds. However, in the SSIS package, the SQL task completes successfully, and then it hangs indefinitely on the data flow step. In the Data Flow tab, none of the boxes are even turning yellow. Why won't it complete? When I move the Exec SQL Task to another container, the package executes fine, but it should be in the Load Phase container.

Hi All,
We want to take advantage of the performance benefit provided by SQL server destination in our packages. We are using a configuration variable to specify whether the SQL Server is remote or local to the packages. We are using a conditional split to redirect the process to either SQL Server destination or OLEDB destination based on the value of the variable. Is there any performance benefit in doing such a thing as it seems that the connection is made in both the paths during the runtime instead of in one particular path alone.
Thanks in advance

Good day,
I'm working with SSIS on SQL Server 2005 and trying to update a table with a OLEDB Destination.
The table I'm updating does not accept Null values. I've tried to update the table in several ways.
Using a "Table or view - Fast Load " Data Access Mode. I get the can't load data due to "Null values are not accepted in field xyz"
Using SQL Command text. Used the isnull function on all null fields and the "Failure inserting into the Read Only Column xyz"
I've check the properties of the table I'm writing to. I've check my user credentials.
Can any of you shed some light on what I'm missing.
thanks

Hello,
I am a beginner for the SSIS and would like to know how to modify the OLDEB Destination connectionString property at run time like using "for each loop container".
My requirement is that I have a single source which would be Sql Server 2005 and my destination is in MS-Access database residing in 100 places. I do not want to manually design in the data flow to these 100 destinations.
I have all the destinations stored in a table and would like to pick these destinations from the table and loop through the same at run time by modifying destination connection string.
I have planned using dts but the for each loop container does not work through as it works with flat file connection manager , but does not go well with OLDEB connection.
Highly appreciate any help in this regard.
Regards
Sameer

Situation
I have a package with an execute SQL task that truncates the destination table as the first step in the control flow and a data flow task that reads data from a flat file and loads a sql server table.
Once in a while the package bombs because it cannot get access to the flat file. The end result is that the table is empty because the truncate runs first. Obviously, I need to address the file contention, but I was wondering how to address this issue in general since anything that causes the data flow to blow up would leave the table empty.
I would rather have the table with day old data than empty, since it is not mission critical and the users can at least look at yesterday's data as opposed to nothing.
Question
Is there a way to specify a "load replace" on the OLEDB destination? I haven't seen one and I guess it makes sense because the data flow task transformations run row by row.
The only solution that I have come up with is to have the following on the control flow:
1) data flow task which reads flat file and loads a temp table
2) execute sql task to truncate the "real" destination
3) data flow task to move data from temp table to real table.
Anyone else come up with a better way to handle this?
Thanks!!

Hi
How can commit interval for OLE DB destination be set when the data access mode is not "fast load".
What happens in oledb destination in case of a failure in package? How does the roll back happens. I mean how is the commit point set in oledb destination? I know about the transaction options which are at the package level.
Thanks,

Overview of my scenario: i have an SQL table with 10 columns. I read data off a csv flat file source and insert / update them into the sql. No problems there.
Now, after the 10th column, the columns are variable from site to site. Ie, for any customer, the first 10 columns are the same but the following 'n' number of columns can be different.
I'm already able to detect what are the 'custom' columns from the source db and can programmatically add / modify the columns to the destination sql tables when SSIS runs.
My problem now is, i have the flat file source with 'fixed' and 'custom' columns together, and my sql table is ready to receive them, but i don't have the proper column mappings in my SSIS package. I only have mappings for the 'fixed' columns.
How can i programmatically 'add' these mappings to my data source and subsequently my oledb destination?
What strategy should i use? Open for anyone's suggestions or ideas.
Thanks.

Hi,
I have a simple loading to excel destination. It has 900,000 records. In 66,000+ records, i has an error

I assume that this is caused by the no. of records im loading since the .xls file can only contain 65,000 records.... i tried using the .xlsx file but i guess it only accepts .xls.
What's the alternative to load to excel 2005 with this numbers of records?
thanks.

I have a dataflow in my SSIS Package that is supposed to transfer over all the rows from a SQL server table. I am selecting columns from the SQL table and there is a total of 1603 rows. I am only getting 354 rows in the DB2 destination table. I have turned on SQL logging and specifically the BufferSizeTuning option for this dataflow. in the Sysdtslog90 table I see messages about the "Rows in buffer type 0 would cause a buffer size greater than the configured maximum. There will only be 1249 rows in buffers of this type" and "Rows in buffer type 3 would cause a buffer size greater than the configured maximum. There will only be 1251 rows in buffers of this type"
I have the following set in the Dataflow properties.
DefaultMaxBufferRows = 5000
DefaultBufferSize = 10485760
The server is windows server 2003 x64, SQL Server 2005 sp1 resides on this server where the SSIS packages are running also. 12gb of ram.
Any suggestions how i can get all the rows transferred, what is Buffer Type 0 and 3? this doesnt seem like a lot of rows (1603 total) to hit a DB2 destination with.
Any settings I would need to check in the Connection Manager? I am using Native OLE DBMicrosoft OLE DB Provider for DB2.

I have a Dataflow task with oledb source that is using SqlCommand to retrieve data and oledb destination to write the source output to a table. I have access to both the source and destination databases.
The problem is the destination component is not writing any rows to the destination table eventhough the Source component is returning rows (I can see them in the Preview and the source database table as well).
I'm using "Table/View Name from Variable" for destination.
The Package executes without any errors but there is no output.
Any ideas?
Thanks.

Hi ,
I have a Package Consisting of the following (tried to portray the flow below)
1) OLE DB Source (Which I set the sql command for in code)
|
/
2) Rowcount Transform (Counts the Source Records)
|
/
3) Derived Column (Adds An AuditJobID ,ExecutionStartDate)
|
/
4) Conditional Split (Splits New and Updated Record - My Implementation of SCD)
/
/ /
5) Rowcount Transform (Counts the New Records) Rowcount Transform (Counts Update Records)
/
/ /
6) OLEDB Destination OLEDB Update Command
I am trying to map the columns in the "OLEDB Destination" with c# ,with the following
IDTSInput90 input = oledbDestination.InputCollection[0];
IDTSVirtualInput90 vInput = input.GetVirtualInput();
As soon as I call the input.GetVirtualInput(); method I get a com exception ,Seem that I am missing a
VirtualInputColumnCollection on the component ,but can't seem to figure out why.
When I drop the all the other components and only keep the OLEDb Source and OLEDB Destination with a flow between them , the call to input.GetVirtualInput() doe not fail with a com exception and I can mapping normally
I really need some guidance on the above.
Regards
Cedric

Hi
I have a made a simple mapping connecting source and destination on SQL server on local box. I am getting ~36K rows/min as the thru put. I only want to use ole db destination data access mode as SQL query (dnt want to use fast load).
I am doing this test in order to set a bench mark for a custom component which i have developed. With this result i can figure out how much time my custom component is taking.
Experts, please let me know your views on the thru put which i am getting is it good bad or ok with the scenario i am testing and also if there are some ways to improve it.
Thanks,

Hello,
I've searched around and can't find any references to the problem I'm having. I'd appreciate any ideas or input.
I'm trying to use the OLEDB Destination for an insert at the end of a long data flow. I need to parameterize the input, and for some of the columns I need to use literal values instead of parameters. It seems like this should be the most common thing in the world, but I'm at a loss to get it to work.
I type in the SQL statement just like I would with an OLEDB Command transformation, with the ? character for the appropriate columns in the VALUES clause. However, when I try to use Parse Query I get this error:
"Parameter Information cannot be derived from SQL statements. Set parameter information before preparing command."
OK, so I start searching around for ways to set the parameter information. Nada. On the Mappings tab the parameter list is empty. I check MSDN and it says this:
"If you have entered a parameterized query by using ? as a parameter placeholder in the query text, use the Set Query Parameters dialog box to map query input parameters to package variables."
Set Query Parameters dialog box? I don't see this anywhere. What am I missing?
The options with the SQL Server Destination seem even more limited, as I don't see any way to use a SQL statement or stored procedure.
For the moment I'm going to stub this off with an OLEDB Command transformation with a downstream Trash desintation, but hopefully that's only going to be temporary.
Thanks,
Dan

Hello,
My OLE DB Source is getting data from the following column types:
ID varchar(50), Name varchar(100), Date datetime, Currency char(3), Cost numeric(30,10)
My OLE DB Source outputs my information in the following order when I click Preview:
ID Name Date Currency Cost
When I connect the OLE DB Sorce to a Flat File Destination, it comes out in the wrong order.When I examine the "line" between them (Data Flow Path Editor) I get:
Currency DT_STR Length: 3
ID DT_STR Lenght: 50
Name DT_STR Lenght: 100
Date DT_DBTIMESTAMP
Cost DT_NUMERIC
What is the easiest way for me to change this so the Flat File Destination will output my data in the same order as the OLE DB Source:
ID Name Date Currency Cost
Thank you very much!

I have an OLE-DB Command transformation that inserts a row. If the insert SQL command fails for some reason, I use the "Redirect Row" option to send the row to a script component. Inthere, I get the error description into a string variable in order to log the error into an error table.
For example, if a primary key violation arises, I would like the error description to be "The data value violates integrity constraints". I get it using the ComponentMetadata.GetErrorDescription. When I use the "table or view mode", I get the error description above without any problem. But If I use the "table or view fast load", the description is something like "No status available". But, If I use the error output to fail the component, in the OnError, I get the right error description. Is there a way to have both behaviour, I mean, to be able to redirect error rows to an output and have the cotrrect error description (like the one in OnError event handler) using fast load mode?
Thank you!

I have requirement to update/insert the DPID based on the address which are passed as an input values.There are more than one address at the same time and I configured to get the address from the query which are correct and output of the address values will be stored as system object variable.I am then passing the system object variable to for each loop container and I have configured the collection and variable mappings as a variable for each input value.
when I pass the value manually to the web service task it works correctly.When I pass it as a variable to web service task it doesn't return any value.I have a data flow task which converts the ouput from web service task using the xml source converts it to oledb destination.I don't see any rows being written to the target table.

I have to combine data from DB2 and SQL server and do some manipuation. I wanted to do union all and put in temp table for further manipulation. I created a temp table in control flow,Â
CREATE TABLE ##SiteTemp

   LEVEL2 VARCHAR(20),
   LEVEL3  VARCHAR(25)
Then I was trying to use that temp table for destination but I can do see that in destination. I have to automate the package and do that everyday. I read some blogs but did not understand how they did it. I did set retainsameconnection to true. I did find this thread but i did not understand how it was done. URL....
I have two OBL DB sources, Then I have Union ALL and then OLE Destination in data flow.I have the temp table code in Execute sql task.

For both OLEDB destiantions (and hopefully for the forthcoming ADO.NET destination adapter) it would be useful to have the following two output columns: NativeErrorCode and NativeErrorMessage.
For SQL Server, this would allow you distiguish between multiple errors which all roll up to the SSIS error "the value violated the integrity constraints of the column", which is way too generic for proper decision making (via conditional split).
For example, like SQL Server replication, you should be able to ignore duplicate key errors (error number 2627) indicating the record existed, but error out on nullability constraint errors (number 515) in which the record could not be inserted. If you had a native error code, you could make this decision, while the SSIS error for two different native errors is precisely the same.
There is a known and accepted race condition between a lookup transform and subsequent OLEDB dest insert attempt (assuming a non-transacted container and a common component target table), which is why the 2627 can be safely ignored in certain instances, while a 515 should not be.

Hello, I wanted to do the following.
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.
Any ideas please

Hi,
We are processing 60,00, 000 rows(2 GB file) available in a flat file and loading them in to a database tables using OLEDB Destination components. In the data pipeline of an SSIS package we have 1 flat file source reader, 7 look up components(full cache mode), 1 multicast component and 2 OLE DB destinations with fast load option.
We have observed that first 10,00, 000 rows are processed and loaded in to target tables in just 4 minutes time. The second set of 10,00, 000 rows are processed in 15 minutes time. After this for processing each 1,00,000 rows SSIS is taking approximately 8 - 10 minutes time. We are not able to identify the reasons for the unexpected behaviour of SSIS.
We thought that as the input file size is 2 GB SSIS is not able to manage and slowing down over time of execution. We did split the big input file in to 60 small 37 MB (approx) size files. Then we modified the package by adding For-Each loop task to process all the 60 small files and load them in to database server sequentially. Even in this approach also we have identified data loading has slowed down drastically after processing 13 files.
In order to verify is there any problem with reading source file or transformation, we have replaced OLEDB destinations component with Flat File destinations. With Flat file destination the time taken for processing rows is very constant. For every 8 minutes package is able to process 10,00,000 rows and write them in to the destination files. So, there is no problem with the with either Look up components or flat file source reader.
We are sure that target database server is in same state/condition from the starting to the end of package execution. The client box in which we are running the package is having 1 GB RAM. During package execution time the CPU usage is at 30 % and PF usage is 580 MB. SP1 is also installed on both Client and Server.
Does any one have clue what is causing slow down of data load over the time of package execution?
