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.
(Microsoft Visual Studio)
===================================
Exception from HRESULT: 0xC0202042 (Microsoft.SqlServer.DTSPipelineWrap)
------------------------------ Program Location:

Some one can tell me what is the reason, or give me some examples.
Hi, I want to transform an xml flow to an html flow. For this, I create an XmlDataDocument, I add on it, all that I want, and I store it in a file (in a dataflow task). After that, in an xml task, I set the input properties like that: Operation type: xslt SourceType: File connection Source: ras.xml
All works fine. But now, I want to use a variable to store my xml data. So, instead of storing my data in ras.xml, I store it in a variable like that:
Dim v As Microsoft.SqlServer.Dts.Runtime.Wrapper.IDTSVariables90 Me.VariableDispenser.LockOneForWrite("RAS", v) v("RAS").Value = doc.OuterXml v.Unlock()
and in the xml task, I set configuration like that:
But when I execute, I got this following exception:
Error: 0xC002F304 at Format HTML Mail, XML Task: An error occurred with the following error message: "Root element is missing.". Error: 0xC002928F at Format HTML Mail, XML Task: Property "New Source" has no source Xml text; Xml Text is either invalid, null or empty string.
Furthermore, when I want to debug it, in replacing the xml task, by a script task, I can see that in my RAS variable, I get the xml data which is well formed.
I was trying to load data using SSIS, Data Flow Task, OLE DB Source, source was a view to a OLE DB Destination (SQL Server). This view returns 420,591 rows from Query Analyzer in 21 seconds. Row length is 925. When I try to executed the Data Flow Task from SSIS, I had to stop the process after 30 minutes, because only 2,000 rows had been retrieved. I modified the view to retun top 440, 000 and reran. This time all 420, 591 rows were retrieved and written in 22 seconds. Next, I tried to use a TOP 100 Percent. Again, only 2,000 rows were return after 30 minutes. TempDB is on a separate SAN Raid group with 200 gig free, Databases on a separate drive with 200 gig free. Server has 13 gig of memory and no other processes were executing.
The only way I could populate the table was by using an Execute SQL Task and hard code an Insert into table selecting data from the view (35 seconds) from SSIS.
Have anyone else experience this or a similar issue? Anyone have a solutionexplanation?
, Hi In this code how can I create a new data source and new data source view and model and structure that it run dynamic. In this code I have a lot of errors, that they are about server and database don€™t have in current code, In this code, first I should definition server or no?
How can I create data source and data source view and model and structure? Please say code of that, and guide me. databasename and srv is unknown. Do I add other reference with analysis services? Please explain about these codes: ************************************************************************ 1) RelationalDataSource dsNew = new RelationalDataSource( datasourceName, Utils.GetSyntacticallyValidID( datasourceName, typeof(RelationalDataSource)));
I am trying to get source code of a view (SELECT part) into an TSQL variable, but I have no idea, where to find this source code and how to proceede the assignment ? Any idea ? thanks
hi everybody, i want to create data source and data source view for data mining, with using C Sharp. i have create data source and data source view and export to XML file, but when i change to another computer, run those XML file, it return error, when i run statement to create and biuld mining model, what can i change on xml or how to run XML on another computer sucessfully, and have i build data source and data source view, how to do it.?
I have a SP that outputs a valid XML record set. Using a Execute SQL Task, I can put the XML results into a string variable. When I try to use the variable in an XML Source nothing happens and I get no error.. If I access the same XML from a file, I get the desired results.
I am trying to have a DataReader Source that can run a variable which I used to store the SQL statement. For example, I have:
Variable #1
Variable name: tablename
Data Type: string
Value: "name_of_table"
Variable #2
Variable name: sql_stmt
Data Type: string
Value: "SELECT * FROM " + @tablename
I want to use DataReader Source to run Variable #2 in the SqlCommand that connects to an ODBC connection. If it is possible by any way, please let me know. Thanks in advance.
I am using a table variable as a source in my OLE DB Source task ( I declare and populate this table variable from TSQL script) to load data in my destination table however the data gets lost after the task, ie I can preview the data from the OLEDB Source task but when I go to the next task which is multicast tranformation the data is lost, I have used data viewers to see the data but they dont have any rows, any help is appreciated.
I read several posts on this topic and I would like to confirm my understanding.
This question has to do with parameterizing the select statement in the OLE DB Source editor. Initially, I thought I could use Data access mode: SQL command, and somehow use a user variable in there to build my Select statement.
But in researching further, it looks like I need to store the entire SQL command in a one long string variable (let's call it A), where A is built off of another variable that has my parameter. I then use A in Data access mode: SQL command from variable.
Am I correct? And is there not a way to accomplish the samething with only one variable that is your parameter value?
It seems a bit clumsy to store the entire SQL expression in a string variable.
I have a package-level variable [User::viewName], type = string, containing a view name. I want to setup an OLE DB source to use this variable value as the source, so Data access mode = "Table name or view name variable". The Variable name dropdown contains [User:viewName], so I select it. When I click OK to leave the edit dialog I get the error:
The variable User::viewName is required to be of type "VT_BSTR".
Only variables of type String occur in the Variable name dropdown; if I try changing it to a type other than string it doesn't occur in the dropdown. What is VT_BSTR and how can I change the variable type to it?
Using Jamie's, John's and Rafae post i have got this far. My scenario demands me to do an incremental load. So i have followed your article and have created a one variable 'vDate' (Dataflow Task, Datetime, 3/3/2008) and another variable SourceSQL (Dataflow Task, String). I have set this SourceSQL evaluation to True and have added this; "select * from stagingperfdata where startdatetime = "+ (DT_WSTR,10) @[vDate].
I want to call this within a OLE DB source, so i select the data access method to SQL command from variable. My variable name is visible and i am able to select it and then save and debug. I also have a derived column transformation to increment the variable vDate by one day. The flow is successful but there is no records written to the target. I tried the same query (available in the variable's value column) in SSMS and it is retrieving 12 records. I went back to the Ole Db source and wanted to preview the data, but i get "Query timeout expired (Microsoft SQL Native Client)" error. Am i missing something fundamental?
We can pass XML to the XML Source in a variable, but I haven't seen anywhere how much data can be passed this way? Is there a limit beyond the limits of system memory?
Also, what data types are valid for the variable? Just String?
We are storing incoming flatfiles into a text field in a table and then we are processing this table on a regular basis. What I would like to do is to get this flatfile from the textfield and populate a flatfile source with it, but so far I have only been able to do that with XML files as there are no option for doing that with the flatfile source. Using the disk as a temporary storage for the flatfile is prohibited.
Does anyone have any suggestions on how to solve this?
Hello. I€™m new to SSIS. This forum and Kirk Haselden€™s book are my teachers. I€™m having a hard time grasping something basic to get started defining a set of packages to automate the ETL process, however, and perhaps I€™m simply misunderstanding the best practices of SSIS.
I have source data in two different transactional databases, and use OleDb connection managers (and OleDb Source components in the Data Flow) to extract the data. I use a Script Task and several Lookup widgets in the Data Flow to transform the data, and output each to two different package-scope DataSet variables.
How do I join these two datasets in a third Data Flow task for loading into my data warehouse? It seems I can iterate through them in the Control Flow, but I can€™t write a query against them in the Data Flow, since there is no connection manager that allows me to €śconnect€? to a package-level variable. Should I instead be storing my extracted, transformed data in temporary database tables, and then joining these to do the final load?
Any advice greatly appreciated. Thanks in advance.
I have created a DTS Package in Integration Services 2005. Within the DTS Package declared a variable named xxx and passed a value 1234.
In the control flow i dropped a Data flow task and in the Property Expression Editor of DataFlow Task i defined Property = [DataReader Source].[sqlCommand] Expression = Variable name.
Now in the DataFlow Task Canvas dropped DataReaderSource.
How can i pass variable value to the SQLCommand ="Select * from table where name = Variable value.
Is there a way to configure the XML source component to use a schema file whose filename is in a variable? Now I know it doesn't make any sense to have an XML source whose schema can vary, however, I have a parent package with a ton of child packages, all of which process the same XML input using the same schema. What I would like to do is for the parent to load the filename of the XML input file into a variable, and the filename of the XML schema file into another. Each child would have its XML source configured to pickup these variables from the parent, so that if the location or name of the schema changes, I don't have to edit each package one-by-one. However, it doesn't seem possible to specify anything but a filename for the schema. Any suggestions?
I am trying to make a SSIS package that will loop trough all files in a directory and load information from them.
I can do this with Raw File Sources since they allow me to use a variable name as the file path, but I cant seem to do the same with Flat File Sources. Is there a way to change the connection to a Flat File Source on each iteration of a loop? Actually, if this is possible with all types of file sources (like excel files) I would love to know about it too.
I was thinking about renaming the file through a script task but that does not seem like the most elegant solution so decided to see if some one here knows of a more proper way before I go that direction.
Can I design data flows with an XML Source pointing to file system xml files, and but run them against variables? I can see the properties at design time (Accessmode=0,1,2; XMLDataVar="User::XMLData), but the XMLSource object doesn't appear to have expressions enabled to change this at runtime, nor do these properties seem to be exposed to configurations.
The scenario:
I have a package that reads through (potentially thousands) of XML files, and having identified the embedded message "type", transforms them via XSLT to an easier XML format (XML Datasource can't cope well with multiple namespaces etc). Then send this the new file off to a type specific dataflow task to send contents to database.
For performance (and other) reasons I'd rather XSLT to a single shared variable and use this variable as the XML source in the data flows (Rather than writing out to the filesystem [via xslt] and immediately reading it back in each time [via datasource]).
But designing the data flow task using a variable as xml source is frustrating for a bunch of reasons - not the least being:
(a) The variable needs to be populated with sample xml data at design time. But this could only ever match one dataflow at a time (fine at run time, but painful at designtime - leading to validation errors popping up all around the place.)
Yes I could have a seperate variable for each xmlsource - but that just makes things more complicated up front and also leaves me with 20+ large, type specific, xml variables floating around at runtime of which only one is ever being used per import - which just doesn't feel right to me.
(b) populating the variable with sample xml at design time is painful due to it being a string - and not accepting hard returns etc that are in text files, design time changes etc)
Using a file XML source at design time is infinitely easier, when I get a design time change - I can just amend the XSLT and run the appropriate task to produce a sample XML file to design against.
I have a fact table which is a custim query in the data source view, I process and work with the data, after somewhile I make some changes in the data source view query but all my changes does not reflect in the cube after processing the same old data returned.
Is it possible to use a stored procedure in a Data Source View? When I use the wizard to create the Datasource View, all it lets me choose is tables and views in the database. Am I missing something, or trying to do something that is impossible?
How does the report model know what data source view to use? I could not find it defined anywhere in the .smdl file.
My problem is this. I have a Report Model project with two data sources, two data source views and multiple report models. When I try and bind a data source to an entity in the report model I do not get to choose which data source view to use to choose what table/view I want to bind the entity too and only the tables in one of my DSV's shows up. When I first created it, it worked fine. It automatically selected the correct view and table and was successfully created but now when I open the project, that correlation is lost.
Is there a limit on the number of fields that can be displayed in a table object in a data source view in SSAS 05? One of the tables (the fact table) in my data source view is displaying only 50 fields. The table actually has many more than that. One of the fields that is not displaying is a foreign key that I need to link to a new dimension table. I have tried refreshing the view, but it doesn't bring in any additional fields.
Hello, We have a need to create a variable within a View. We tried declaring our variable like we would in a stored procedure, but that doesn't seem to work. What is the proper way to do this? Thank you. Kay
We have a job running the SSIS Package. I am working with that SSIS Package. The SSIS package has a script task. In the script task they used the variable of source path. I want to change the value of that variable (Need to modify the source path).
I modified the variable value in that package and in the config file but getting error message
Exception has been thrown by the target of an invocation.
I am wanting to capture the file name I am using to load data from and use it in a SQL statement to insert it along with the data that I load.
I am using a ForEach container to load all my .txt files but cannot figure out how to capture the name of each source file as it loops through the files and then add it to my insert statement that is populating my history table. I would think that the ForEach container has that information, but I do not see how to access it and assign it to a variable that I could use in my SQL statement.
