I need some help determining the best way to accomplish my task. The workflow starts by generating a list of unique ID's from a local table. Then take that list of unique ID's and query an Oracle table for all matching records.
My thought was to first use an Execute SQL task with the following SQL:
select projectid from projectlist group by projectid
with Result Set configured as follows:
Result Name = projectid
Variable Name = varProjectIDList
Then in the Data Flow Task add a DataReader Source to pull the matching data. Here's where I'm getting hung up. I'd like to pass the result set from the Execute SQL task. I tried the following SQL but it doesn't work.
select * from masterlist where projectid = @[User::varProjectIDList]
I'm open to any suggestion on the best way to take my unique list and use it as input for a query against my Oracle DB.
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.
The SQL computed is complex enough that I can't see a way to make it a parameterized query. The obvious approach seems to be to compute the SQL in a CONTROL FLOW SCRIPT TASK and then use it to load a variable to set the VARIABLE SOURCE of a CONTROL FLOW EXECUTE SQL TASK.
I see that I can return a resultset to a variable.
But getting the rows of the results into a dataflow is not obvious. I have heard mentione that a Derived Column can do this. I can see using a dummy SCRIPT COMPONENT as DATA SOURCE with nothing in it to then drop into DERIVED COLUMN. But when setting up DERIVED COLUMN I don't see how to pull the columns out of the RESULTSET variable.
If it makes a difference I think the columns of the resultset will always be the same in this scenario.
Maybe this is totally the wrong approach? Any clues would be appreciated.
I'm just starting off in SSIS and have a question that I can't find an answer to...
I'm loading in a number of files (in separate Data Flows) and performing some transformations on them before merging them back together. What I'm not sure about is what I should be doing with the data at the end of each of my "Import Data From XXXX Flat File" Data Flows. Am I better off using OLE DB Destinations (or SQL Server Destinations) and saving this intermediate data to temporary tables, or am I better off using a Raw File Destinations and saving this intermediate data to files? Or is there, perhaps, a better option that I'm currently unaware of?
If the Raw File Destination is the way to go, then isn't there a maintenance issue with cleaning up all the files created? And will there not be a management issue to ensure that there is sufficient disc space available on the drive you are saving to?
I'm a bit confused and overwhelmed by SSIS at the moment, so any help would be much appreciated!
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:
hi, like, if i need to do delete some items with the id = 10000 then also need to update on the remaining items on the with the same idthen i will need to go through all the records to fetch the items with the same id right? so, is there something that i can use to hold those records so that i can do the delete and update just on those records and don't need to query twice? or is there a way to do that in one go ?thanks in advance!
Hi, I want to insert line feed. I have used char(10) and char(13) function. But I could not insert line feed. Ex: set error1= 'error description' + char(10)+ 'Employee' Output must be: error description Employee Any suggestions are welcome.
I would like to know what Data Feed means while working as an Administrator on Ms SQL Server 2000? Also what do you mean by integrating feed of data? I would appreciate it if anyone could help me out with this queries... Also I was wondering which would be best book to refer while learning about ms sql server 2000.
Hello,I have an XML data feed that I would like to use to create tables inSQL Server. The xml data feed consists of a large amount ofinformation that changes on a regualar basis. Is there a way toautomatically create SQL Server tables using the data feed?ThanksBilly
I am using SSIS in SQL Server 2005 and want to have a query like this in my data flow task
Select a.* from abc as a inner join (Select max(b.id) as ID from xyz as b inner join pqr as c on b.id = c.id and b.id > ?) as t1 on t1.id = a.id
SSIS fails to detect the parameter (?) for the inner query and gives message.
" Parameters cannot be extracted from the SQL command. The provider might not help to parse parameter information from the command. In that case, use the "SQL command from variable" access mode, in which the entire SQL command is stored in a variable.", so assuming this is your problem, then you can workaround.
"
The idea is to parameterize the inner query ,,, (so if the above query doesnt make sense ignore it )
In the data flow task, i have thosands of rows flowing, now just before inserting these rows into a table, i want to delete some rows in the destination table. For this, if i use the oledb command, then it will run several times. I think a script can do it but I want to avoid it because it would be an inefficient affair.
I need to have an automated process to read data from DB2/AS400 and feed it to SQL Server 2000. Has anyone done this before? Any suggestions how it may be done? I know my company doesn't want to spend a lot to do this.
Does anyone know where to start if I want an exported copy of homeappliances, cars, cell phones etc.I just need to populate my database and I want to get some data feedfrom all the different types of manufactures.I think there are services out there. But I have not seen one.I want a CSV file that has all the make/models for lets say: TVs
I need to pass a parameter from control flow to data flow. The data flow will use this parameter to get data from a Oracle source.
I have an Execute SQL task in control flow to assign value to the Parameter, next step is a data flow which will need take a parameter in the SQL statement to query the Oracle source,
The SQL Looks like this:
select * from ccst_acctsys_account
where to_char(LAST_MODIFIED_DATE, 'YYYYMMDD') >?
THe problem is the OLE DB source Edit doesn€™t have anything for mapping parameter.
I have an Execute SQL Task that returns a Full Rowset from a SQL Server table and assigns it to a variable objRecs. I connect that to a foreach container with an ADO enumerator using objRecs variable and Rows in first table mode. I defined variables and mapped them to the columns.
I tested this by placing a Script task inside the foreach container and displaying the variables in a messagebox.
Now, for each row, I want to write a record to an MS Access table and then update a column back in the original SQL Server table where I retreived data in the Execute SQL task (i have the primary key). If I drop a Data Flow Task inside my foreach container, how do I pass the variables as input to an OLE DB Destination on the Data Flow?
Also, how would I update the original source table where source.id = objRects.id?
Thank you for your assistance. I have spent the day trying to figure this out (and thought it would be simple), but I am just not getting SSIS. Sorry if this has been covered.
Dear All! My package has a Data Flow Task. In Data Flow Task, I use a Script Component and a OLE BD Destination to transform data from txt file to database. Within Data Flow Task, I want to call File System Task to move file to a folder or any Task of "Control Flow" Tab. So, Does SSIS support this task? Please show me if any Thanks
I'm currently setting variables at the package level with an ExecuteSQL task. This works fine. However, I'm now starting to think about restartability midway through a package. It would be nice to have the variable(s) needed in a data flow set within the data flow so that I only have to restart that task.
Is there a way to do that using an SQL statement as the source of the value in a data flow?
OR, when using checkpoints will it save variable settings so that they are available when the package is restarted? This would make my issue a moot point.
I have 1 table that is just a list of feeds. A, B, C, D etc (15 rows in total) and each feed has other information attached to it such as Full name, location etc etc. I am only interested in the Feed column.
Each feed then has a corresponding data table which contains a list of records. Eg Feed A data is contained in TableA, Feed B data is contains in TableB and so on.
Basically what I need is a combined table that shows the list of Feeds in the 1st Column ( So A, B, C, D…..) and then a second column which counts the records from each separate data table corresponding to that feed.
So the end result would look something like this:
Feed------No of Records A----------4 (from TableA) B----------7 (from TableB) C----------8 (from TableC) D----------1 (from TableD)
I'm trying to find a way to import data from this data xml feed to get daily exchange rate. I' tried:
select * from openrowset(bulk 'http://www.bankofcanada.ca/stats/assets/xml/fx-noon.xml',single_blob) as x
Which is a feeble attempt at a start; however, am getting this error message:
Cannot bulk load because the file "http://www.bankofcanada.ca/stats/assets/xml/fx-noon.xml" could not be opened. Operating system error code 123(The filename, directory name, or volume label syntax is incorrect.).
Hi all! I recently started working with SSIS and one of the things that is puzzling me the most is what's the best way to go:
A small control flow, with large data flow tasks A control flow with more, but smaller, data flow tasksAny help will be greatly appreciated. Thanks, Ricardo
I am trying to use FOR XML under SQL Server 2014 to write out a large XML data set. I want it to look like

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.
My first post here. I have an Analysis Services Cube and I need to export some of its data into a flat file (a semicolon separated value file) with fixed length columns.
What I have in Integration Services now is:
DataReader Source (ADO.Net conection) Data Transformation (NTEXT -> WSTR) Derived Column (WSTR -> STR, and some ISNULL validation) Flat File Destination (Delimited by ";")
the thing is I have all the measures and calculated measures in the cube formated with format strings and they work fine when I do a query through the SQL server Managment Studio, but in Integration Services before the columns are written into the file they lose its format.
for example, I have a calculated member called "Deuda Total Nacional" that returns something like this +0001234,00 and I need to take off the decimal separator so it is written into the file like this +000123400 , I'm doing it this way
(ISNULL([Deuda Total Nacional]) ? "+00000000000" : REPLACE([Deuda Total Nacional],",",""))
I am wondering if it is possible to use SSIS to sample data set to training set and test set directly to my data mining models without saving them somewhere as occupying too much space? Really need guidance for that.
Hello. I currently have a website that has a table on one webpage. When a record is clicked, the primary key of that record is transfered in the query string to another page and fed into an sql statement. In this case its selecting a project on the first page, and displaying all the scripts for that project on another page. I also have an additional dropdownlist on the second page that i use to filter the scripts by an attribute called 'testdomain'. At present this works to an extent. When i click a project, i am navigated to the scripts page which is empty except for the dropdownlist. i then select a 'testdomain' from the dropdownlist and the page populates with scripts (formview) for the particular test domain. what i would like is for all the scripts to be displayed using the formview in the first instance when the user arrives at the second page. from there, they can then filter the scripts using the dropdownlist. My current SQL statement is as follows. SelectCommand="SELECT * FROM [TestScript] WHERE (([ProjectID] = @ProjectID) AND ([TestDomain] = @TestDomain))" So what is happening is when testdomain = a null value, it does not select any scripts. Is there a way i can achieve the behaivour of the page as i outlined above? Any help would be appreciated. Thanks, James.
I am working on importing an Excel workbook, saved as multiple CSV flat files, that has both group level data and related detail row on the same sheet. I have been able to import the group data into a table. As part of the Data Flow task, I want to be able to save the key value for the group, which I will use when I insert the detail rows.
My Data Flow has the following components: The flat file with the data, which goes to a derived column transformation to strip out extraneous dashes, which leads to the OLEDB Destination component.
I want to save the value as a package level variable, so that I can reference it in another dataflow.
Is this possible, and if so, at what point do I save the value?
I have to extract, dayly a list of contacts on a exchange server in a table on our EDW on sql server 2005. Is it possible to get the information directly from a dataflow or i will have to developpe a script task ?
I want to export data from SQL Server2005 to an Excel spreadsheet thru "Data Flow Task". I am using OLE DB for SQL Server for the source connection and a Connection To Excel as my destination source. The Excel spreadsheet (2003) exists and has the first row with column names. I don't have any warnings before trying to execute.
While executing the tasks, I got the error Error: 0xC0202025 at Data Flow Task, Excel Destination [427]: Cannot create an OLE DB accessor. Verify that the column metadata is valid. Error: 0xC004701A at Data Flow Task, DTS.Pipeline: component "Excel Destination" (427) failed the pre-execute phase and returned error code 0xC0202025.
After analysing I found in the DataFlow --> Excel destination --> Advanced Editor for Excel Destination, the default data type for txtRemarks shows as "Unicode string [DT_WSTR]". But this is supposed to be "Unicode text stream [DT_NTEXT]". Even if I change the data type in the design time, It doesn't accept.
