An Execute SQL task takes 1 min to run a statement "insert into Mytable select * from view_using_joins"
Output: 10,225 rows affected.
But a Dataflow task configured to fetch data from the same view_using_joins into MyTable takes hours to do the same.
Could you please explain why is it so ?
Thanks

Hi,
I have a 'Execute SQL Task' in my 'control flow', my 'Execute SQL Task' will return a value which I am assigning to a variable. Based on the value of the variable, I need to control my other flows. If the variable's value is 1 then I should invoke a dataflow, else I should write a failure error message in event viewer. Please could someone provide some inputs on how this can be done.
'Execute SQL Task' ----->value 1 ------>data flow to be executed
'Execute SQL Task' ----->value !=1 ------> write some error message in the event viewer and no tasks should be executed after that.
Thanks

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.

Does anyone have any idea what I might be doing wrong?

1 :Control Flow Excute SQL task: Truncate Table
2: Dataflow Task: Datareader--Script componant--OLE DB Destination (SQL Server 2005--a single table --always around 600,000 rows)
How do I set up a transaction where if there is a failure the Truncate Table command will roll back---and the OLE Destination (A single SQL Server table) will be left the same as before the load started.
Another question with that volume of data --600,000 rows will a truncate table be pratical in a transaction
Any ides welcome
thanks in advance

I'm using SSIS in Visual Studio 2012. My Execute SQL Task calls a Stored Procedure where I have a TRY-CATCH. Last week there was a problem and the CATCH was executed and logged an error to my error table, but for some reason the Execute SQL Task didn't fail. Is there a setting to make the Execute SQL Task fail when an SP encounters a failure?

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?
Thanks.
I have a SQL Task that calls a stored procedure and returns an output parameter. The task fails with error "Value does not fall within the expected range." The Stored Procedure is defined as follows: Create Procedure [dbo].[TestOutputParms] @InParm INT , @OutParm INT OUTPUT as Set @OutParm = @InParm + 5 The task uses an OLEDB connection and has a source type of Direct Input. The SQL Statement is Exec TestOutputParms 7, ? output The parameter mapping is: Variable Name Direction Data Type Parameter Name User::OutParm Output LONG @OutParm

Hi everyone,
For first time I'm testing this task and surprisingly, when I try "Edit Package" option:
1)The DTS host failed to load or save the package properly
2)The selected package cannot be opened
3)Error HRESULT E_FAIL has been returned from a call to a COM component
But after these messages you can see all the tasks but they haven't name!!
It seem as if RCW mechanism has failed between managed and unmanaged coded-partially.
I don't dare to follow doing more stuff, I don't know if that package is well-loaded or not from there. ?¿
Any guidance or idea about this?
"Database in use. The system administrator must have exclusive use of the database to run the restore operation." I created a script in the 7.0 database to reconfig the db to 'dbo use only' and identify and then kill all but the 'SA' and 'NT AUTHORITYSYSTEM' processes but that still is not enough. Can anyone please tell me what I'm missing here?
Thanx.

Hi Pals,
Here is my scenario in my ETL process, I have one DataFlow task.
Assuming that i have 10 clean records in my source database and i need to load all the 10 recs into my target table.
IS there any means of cross checking the no of rows from source table and number of rows loaded into my target table.
Any suggestions are greatly appreciated.
Thanks & Regards.
Hi:
I am getting the following error when I start debugging my Package, I am not sure what this is related to, but basically, input (datatype is a int, and its mapped to a column which is also int), so I am not sure whats happening here. The input column is actually a derived column, and its set as a 4 byte un-signed int, please advice on where should I start looking to troubleshoot this issue. This loanapplicationid is actually a user variable that is utilized by other tasks in my control flow as well:
Error: 0xC020901C at InsertApplicationCL5, OLE DB Destination [16]: There was an error with input column "LoanApplicationID" (1161) on input "OLE DB Destination Input" (29). The column status returned was: "The value violated the integrity constraints for the column.".
Hello all,
I got a text file with two columns. and I need to generate a integer key automatically with the row number (or any distinct number, I thought row number will be OK). and when I make the data flow task to import this text file into a raw file I need to get the unique rownumber as Id.
How can I make this in the data flow tak??
regards,
I written a SSIS package to import a table from one database to another database. I used dataflow task with oledb source and oledb destination with fastload. For 2 million records its taking 5 min . The same import using DTS I am getting in 2 mins. DTS package is more faster than SSIS package ?. any reasons why SSIS is taking more time?
View 4 Replies View RelatedNeed help regarding ssis dataflow task
I need to create a ssis package. I want to import the data from a flat file to a table.
Lets say, the table has 5 columns -- col1, col2, col3, col4 , col5.(Assume that all columns can be NULLABLE) The datafile contains the data related to only three columns say col1, col2, col3. So when I use dataflow task to import the data from the file to the table, I will only get three columns, col1, col2, col3. Columns col4, col5 will be NULL.
However, I want to populate columns col4, col5 with some values which are stored in the variable.
IS there any way to do this??
Any help would be appreciated.

I want to be able to loop through a view and execute a dataflow task for each record. I would like to pass the value of a column to the dataflow task to be used as a parameter in a data reader.
How can I do this?
Hi,
I am getting data from an external source. External data has a column called "Type". I have a variable in my package which contains the list of types as shown below:
Filtered_type_List = 2,4,8,10,11
If this variable(Filtered_type_List) is blank, then I need all the data from the external source and if it is not blank then I only need the records matching to his list. How can I implement this in DataFlow Task?
Thanks
In the control flow I have an "Execute SQL Task" that executes a stored procedure. The stored procedure returns a result set of about 2000 rows of data into a package variable that has been typed as Object to contain the data.
What I have not been able to figure out is how to access the rows of data (in the package variable) from within a data flow task. There does not seem to be a data flow source task to perform that operation.
What am I missing that would make this easy?

Hi,
In terms of data flow tasks, when say we load text files into databases.
Is it possible to have it in a way so that if a certain record (line in the text file) fails to load due to watever reason, it gets written to another table, but the rest of the records still get loaded?
I try to do so and end up with the whole data flow task failing and it stalls at the record that had the error and doesn't seem to continue forward.
I just used the red arrow (on failure) and put that to another SQL destination object. But yeah that didnt work.
If someone has a better way of doing so, would be awesome if you can share that.
Cheers
Hello, to give you a background on where I'm coming from:
I have an SSIS Package with a global String variable that has an sql statement. so it says something like: "Select * from MyTable "
I than have a SQL Script Task where I append a WHERE Statement to my string.
Than in the Dataflow Task when I select the source database, I run command from Variable.
When I run the package I get an error that my string is too long. My string is about 750 characters that I'm trying to pass through.
Is there some limitation to this?
I have ran the raw SQL Command in the SQL manager and it runs fine. I have built a million of these packages, just not one with such a large string.
If it is the case that it is just too long, is there a work around to that?
Thanks,
Rusty.
I have a problem whit loading XML-files into SQL server.
I iterate over the XML-files with the "for each file" component and use the XML source within a Data flow task. This works great until the file count got bigger. After say 1000 files the XML source returns error 0x8007000E. I think this means out of memory. Does anyone have an idea how to solv this. The load must be able to handle up to 5000 files in one batch.
Does anyone know how to create an eventhandler for a dataflow task specific events (OnPipelinePostEndOfRowset, OnPipelineRowsSent, etc.)? These events are available for logging via the standard logging infrastructure, but there seems to no eventhandler for them.
The reason I'm interested is that parsing information logged by these events using builtin log providers is not easy (eg., the number of rows sent gets burried somewhere in the message column (i'm using sql provider). I'd like to capture this information and record it cleanly in a custom ssis metadata database i'm building. Any ideas are welcome. Thanks.

Maybe I am mistaken ( most likely ). But I am missing a dataflow task, which would do something similar like Throw Execption.
The project I am currently working on needs to validate a lot of different data. And sometimes incorrect data ( corrupted, incomplete or unexepected ) is coming from the source system. In case of this I need to trigger an error and discard the complete row or batch depending on the situation.
For example:
In our source system we have some flag fields. And certain combinations of flags are not logical (business rules) but the system allows data to be inputted in this unlogical ways. And because we are creating the system I am expecting some combinations flags which are allowed but not properly defined in the specification.
So when I use a conditional split, I want the default output to trigger an error instead of an output.
How can I pass a variable to a DataReader in a DataFlow task?
My SqlCommand for the DataReader is:
SELECT CustName, CustCode FROM Customers WHERE CustCode = '?'
The DataFlow task is nested in a ForEach loop. I confirmed that the variable is changing with each loop by using a ScriptTaks and a message box. However, the DataReader SqlCommand does not seem to be updating.
I am trying to use an XML Source on xml data from an XML webservice, I am putting the document into a variable the trying to import the data from there with the XML Source, but I am getting an error telling me that truncation occured

The linking column mensioned in the error is sometime quite a long string but there is nowhere in the XML Source editor to change the size.

HI, I have to copy tables (approx. 60) content from one database to another using SSIS. I know that I can call an execute SQL task to execute an INSERT INTO <target table> SELECT * FROM <source table>.
I was wondering if I could use a single dataflow and change its source and target transform data source to do the same as above. In a script component, is it possible to load a package and modify its dataflow to simulate the INSERT INTO <target table> SELECT * FROM <source table>?
Thank you,
Ccote
I was using the code in this thread (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1371094&SiteID=1) to create a console application which can build the SSIS package dynamically and run the package.
If the source column and destination column names are of different cases then the application was failing during the mapping. So I modified the for each loop like below. Still this is not a fool proof method, this will work as long as all characters in the column names are upper or lower.
for eg., Source column = empl_id, Destination column = EMPL_ID, in this case the below code will work. if the source column or destination column is Empl_Id, then the below mapping will fail.
Code Block
foreach (IDTSVirtualInputColumn90 vColumn in vInput.VirtualInputColumnCollection)
{
IDTSInputColumn90 vCol = destnDesignTime.SetUsageType(input.ID, vInput, vColumn.LineageID, DTSUsageType.UT_READWRITE);
try
{
destnDesignTime.MapInputColumn(input.ID, vCol.ID, input.ExternalMetadataColumnCollection[vColumn.Name.ToLower()].ID);
}
catch
{
destnDesignTime.MapInputColumn(input.ID, vCol.ID, input.ExternalMetadataColumnCollection[vColumn.Name.ToUpper()].ID);
}
}
So how can I map the columns irrespective of the cases?
Thanks

Hi All,
I am using a Data Flow task which copies data from an Excel Source to a SQL Database Table Destination. From 15 columns I require only 10 columns to be imported to the DB Table. So I have mapped those colums. In SQL DB there is a colum called say X, whose value should be the "Remedy" for all the columns which are imported. Is there any task that can achieve it.
Please Help.
