Date Problem : Dynamic SQL In An OLE DB Source Component
Feb 21, 2006
Hello,
I have an OLEDB Source component with a Oracle OLEDB connection manager.
In my SQL statement I must do something like this ...
SELECT * FROM OracleTable
WHERE convert(datetime, OracleDate) = parameter
I've dynamicaly build the statement like this : http://blogs.conchango.com/jamiethomson/archive/2005/12/09/2480.aspx
Unfortunately this doesn't work because the variable is a datetime value and not a string.
Maybe another way is to store the date in a table in my SQL database and include it in my Oracle SQL statement ? This would mean that there are multiple connection managers being used in one SQL statement ... I have no idea if this would be possible ...
I have a package that has a data lfow task. this task imports data from a db2 database (using the IBM Ole DB provider fro db2) and adds it to sql server database table. This package was created on the server. then though version control (using TFS source control) I check out the package on my local machine. and when I open the package I get the foll 3 errors.
Error 1 Validation error. Import Account Num from BMGP_BDR: DTS.Pipeline: The component metadata for "component "DataReader Source" (1113)" could not be upgraded to the newer version of the component. The PerformUpgrade method failed.
Error 2 Error loading BMAG Download Xref Tables - bmag.dtsx: Microsoft.SqlServer.Dts.Pipeline.ComponentVersionMismatchException: The version of component "DataReader Source" (1113) is not compatible with this version of the DataFlow. [[The version or pipeline version or both for the specified component is higher than the current version. This package was probably created on a new version of DTS or the component than is installed on the current PC.]] at Microsoft.SqlServer.Dts.Pipeline.ManagedComponentHost.HostCheckAndPerformUpgrade(IDTSManagedComponentWrapper90 wrapper, Int32 lPipelineVersion)
Error 3 Error loading BMAG Download Xref Tables - bmag.dtsx: The component metadata for "component "DataReader Source" (1113)" could not be upgraded to the newer version of the component. The PerformUpgrade method failed.
I have a package which reads an Access file from a folder. My connection manager to this file is .NET providers for OledbMicrosoft Jet 4.0 OLE DB Provider.
Package works from my computer. But when I execute it on the server as a SQL Agent job, I get
The component metadata for "component "DataReader Source" (1) could not be upgraded to the newer version of the component. The PerformUpgrade method failed.
I copied the mdb file to a folder on the server which my packages have no problem reading data from.
My packages run under the same domain account as defined in proxies.
I have a requirment which i have partly accomplished , but could not get through completely
i have a file which comes in a standard format ending with date and seq number ,
suppose , the file name is abc_yyyymmdd_01 , for first copy , if it is copied more then once the sequence number changes to 02 and 03 and keep going on .
then i need to transform those in to new file comma delimited destination file with a name abc_yyyymmdd,txt and others counting file counting record abc_count_yyyymmdd.txt. and move it to a designated folder. and the source file is then moved to archived folder
what i have taken apprach is
script task select source file --------------------> data flow task------------------------------------------> script task to destination file
dataflow task -------------------------> does count and copy in delimited format
what is happening here is i can accomlish a regular source file convert it to delimited destination file --------> and move it to destination folder with script task .
but cannot work the dynamic pick of a source file.
please advise with your comments or solution you have
I have an XML data file and an associated XSD file with properly defined datatypes. However, the datatype of all the data elements are always "string" datatype. For example, in my current xml file, all the data elements are of Decimal datatype which is properly defined in XSD file. However, datatype of all the output columns are of string datatype.
I have a problem of performance with my XML source component. In my XSD file, I have over 300 outputs, for each output of the XML component I generate a Row file (so I generate 300 Row File in the same Data Flow) that I integrate into a table in another Data Flow. When I debug just the data flow of the XML source, it takes much time over 10 hours and the XML source component keeps a yellow color, and it generate empty Row Files, but when I interrupt the debug process it generates the right row files. For information I use a machine with 8 microprocessor and 4GO of Ram, and my XML file has 850KO. So my question is, how can I increase the performance of my package without splitting the XML file. Thank you in advance
Any knowledge of an SSIS source pipeline component which reads the JSON, a data interchage format.
JSON looks pretty tempting for heavy data interchange (somewhat human read-able, name/value pairs + arrays, nesting, lighter weight than most xml serializiers), and if its gaining momentum, I should think a source component would follow on (most likely third party)
I want to use Script Component as Source, but I don't know how to code the output rows. Someone can give me some clue or some sample codes? Thanks in advance.
I need to iterate through a bunch of packages and replace the source component in all data flows with a different source component type. That much I've got figured out, but I'm wondering the best way to fix all the LineageID references downstream.
In figured there would be some helper classes to do that for you or something, but the best I could come up with so far is build a dictionary... the key being the LineageIDs from the source component I just deleted... the dictionary value being the corresponding new column's LineageID. Then I run the following code. Is there a better way?
Also, derived column transforms end up broken because the expression is still referencing the old LineageIDs, so I had to write a RefreshExpression function and run it on each input and output column downstream. That function replaces the Expression (which uses the LineageID) with the FriendlyExpression (which uses the column name). Also, I had to name the new source component the same name as the old so that two-part names (i.e. [My Source].[My Col]) in the derived column expressions would still be valid. There's got to be a better way! And I'm worried that derived column transform isn't going to be the only special case.
While working on a recent project, I needed to import a number of old mainframe generated text reports. Since they didn't work on the one-record/one-row construct, the Flat File Source won't work.
So, I created a custom component that allows you to specify a Regular Expression pattern, and it will parse a text file and return columns. Each capture in the RegEx pattern is returned as a column, and you can also specify column names in the regex with the standard (?<colname>) syntax. The code is fairly basic really, but if you are comfortable with regular expression syntax, it can handle a huge variety of unusual text file formats. It also includes a UI editor for the RegEx pattern property that will allow you to test the pattern against a sample text file; it will highlight each row in blue and each column in green (see screenshot)
Since this might have applications for other folks, I added it to SourceForge under GPL. So if you might find that functionality useful, please check out http://sourceforge.net/projects/textregexsource/ and send me some feedback. There isn't much there yet, so check out the screenshots/news/release notes for the basics.
If there is demand, I'll create a more robust install package and documentation. Also looking for feature suggestions.
I am using XML source component to integrate an xml file into an sql server data base. So for this I have tried to test only this XML component with a small XML file (43 KO) and its XSD (434KO) (not generated using XML component), so my package contain a dataflow with only the XML source component. When I execute the package, in the progress window I get:
1- Validation step 100%, (generate warning, because the outputs are not used)
2-Preparation of execution step 100%
3-Excution step
But when the "Execution step" starts it does not stop and it does not fail, so the XML component keeps the yellow color indifinely and it generate temporary file in "Temp" repository.
I run this package in a box with SQL server 2005 SP2 with, 8 Processor and 4GO of RAM.
So is there any solution or explication for this problem. Is it a limit of SSIS? , and how can I increase the SSIS RAM.
I also generated an XSD file using the XML component, but I get the same problem.
A colleague of mine has discovered some behaviour in the XML Source component that I am having trouble understanding or explaining. Here is the (obfuscated) XML document that we are looking to parse:
I'd like to draw your attention to the bit I've highlighted in red. SSIS has incorrectly defined this attribute as an unsignedLong. if you look at the data above you'll see that it has leading zeros therefore we need it to be interpreted as a string. Unfortunately (and here's the problem) there doesn't seem to be a way for us to change the generated xsd and thus refresh the external column metadata. The only way to change it is to go into the Advanced Editor and manually change the external column and output column metadata.
Is this by design? It seems very limiting if you ask me to not let us have control of what the metadata should be.
I am debugging a Data Flow task in my SSIS package. When I run the package in debug mode, one of the OLEDB Data Sources turns red. I have rerouted all Error Output to a flat file, and put a Data Viewer on that path: no rows get sent. When I click the Preview button on this component in Design mode, I see the expected data and get no error messages. The connection does a simple table access...no SQL command. I don't see anything different between this component and other OLEDB sources in the same package that don't trigger any errors. I've tried dropping and re-creating the component with the same results.
in the acquireconnection method Using the below statment I can get a connection Object
oledbConnection = cmado.AcquireConnection(transaction) as OleDbConnection;
from the connection object I can get the connectionstring from the object by calling
oledbConnection.connectionstring() property which will have all the details like DataBase, UserName & other Inofrmation but there is no password Info.
How to get the password Information, I need that information since I will use that info to make OCI calls to fetch the data from the Oracle database in m,y custome source component.
Hi,I have developed a custom source component to get data from a generic odbc connection with some special caracteristics.
The component works fine by getting and mapping the output fields etc...
The only two problems existing are that when i run the task it says that the data flow has no components inside... how is this possible since i have my source mapped to a flat file inside that data flow?
This is the error:
SSIS package "BVEIT000D.dtsx" starting.
Warning: 0x80047034 at BVEIT000D_<EMPRESA> TXT, DTS.Pipeline: The DataFlow task has no components. Add components or remove the task.
Information: 0x4004300C at BVEIT000D_<EMPRESA> TXT, DTS.Pipeline: Execute phase is beginning.
SSIS package "BVEIT000D.dtsx" finished: Success.
The other problem is that if i want to <ignore> a certain source column the component already shows me an error saying that the no column with ID 0 was found...
Any one with experience in creating custom components?
I need to create an ODBC source script component that outputs into SQL Server. When I debug I get the following error message:

I'm wondering if it is possible to create a flat file source on the fly while bypassing the following step:
On the Connection Managers page, add or create the Flat File connection manager, using a descriptive name such as MyFlatFileSrcConnectionManager. Then close the Script Transformation Editor.
I want to create the connection totally in script, yet i'm having a hard time proving this out...does anybody have any experience with this?
I am trying to figure out how the Excel source component determines that a column in an Excel sheet is a datatype of float when there is no data in the sheet, only column headers.
I created a package and dragged an 'Execute Sql task' from the toolbox onto the control flow. I made the ConnectionType = 'Excel' and then Connection = 'New Connection' and used the dialog to specify a path and also checked the 'First row has column names' box. In the SqlStatement I put the following:
create table `Tab1` (Id integer ,Description nvarchar(255) )
Then I ran the package and it sucessfully created the workbook and the 'Tab1' worksheet.
Now I create a new package and I drag a 'Data Flow Task' from the toolbox onto the control flow. I edit the Data flow task and drag an 'Excel Source' onto the 'Data Flow'. I edit the 'Excel Source' component and click the 'New Connection' button and I browse to the workbook file I created above. In the 'Name of excel sheet' drop down, I select 'Tab1' and click OK. Now when I open the Advanced Editor for the 'Excel Source' and then click on the 'Input and Output Properties' tab, I expand the 'Excel Source Output' node. Then I select the 'External columns' and I select the 'Id' column and I see that the datatype is 'double-precision float'.
I am wondering how SSIS knows that it is a float even though there is as yet no data in the table only the column headers. There does not appear to be any numeric formatting either. Interestingly, if I close the Advanced Editor and then open the workbook and I merely click the 'Save' button without having made any change, then if I again look in the Advanced Editor, it now prompts me that the datatype of the 'Id' column has changed. It seems that the datatype has changed to Unicode string. Can anyone explain why this happens? Why did simply clicking the 'Save' button in the excel sheet cause the datatype to change from float to string. What actually changed in the worksheet? I am using Excel 2003, SQL Server 2005 SP2 and Visual Studio 2003 Pro SP1. Thanks for any insight into this.
Can someone please point me to one or more examples of a Source component that has two or more outputs?
I wrote a source, which works with a single output, but after adding a second output, I see no rows there. I've single-stepped the code in the debugger, and it looks like it should be adding rows to the second output, but the downstream component never sees any.
Does anyone know how to create a Source Script Component programmatically. I can only seem to create a Transformation Script Component. I have this:
PipeLineWrapper.IDTSComponentMetaData90 sourceComponent = ((dataflowTask as TaskHost).InnerObject as PipeLineWrapper.MainPipe).ComponentMetaDataCollection.New();
I have a Data Flow Task. I have one "OLE DB Source" which gets my data from a SQL Server Database. I have a second "OLE DB Source" which uses DATEADD to derive a date qualifier that I would like to use as a date qualifier in my subsequent Excel spreadsheet...opting to use SQL Server and DATEADD rather than messing around with VB syntax to get the previous week date qualifier.I am trying to connect the flow from one OLE DB Source to the next OLE DB Source and get the error..Component OLE DB Source has no inputs, or all of its inputs are already connected to other outputs. You may be able to edit the component to add new inputs to it.Can't I connect two completely different and independent SQL Server queries using "OLE DB Source" within my Data Flow?
Is there any way to store my derived date from my second "OLE DB Source" to a variable so that I cana then use that as my date qualifier within my Excel destination?

Problem:
When adding the DataReader Source component to the package, I cannot assign the Connection Manager. Designer issues the error message:
"The runtime connection manager with the ID "" cannot be found. Verify that the connection manager collection has a connection manager with that ID."
Editing the DataReaderSrc component shows only one row under the Connection Managers tab:
The datareadersrc component editor displays the warning message: "Not all connection managers have been set. Set all connection managers.". Clicking the Refresh button causes the error message to be displayed "The runtime connection manager with the ID "" cannot be found. Verify that the connection manager collection has a connection manager with that ID."
I am prevented from assigning my Connection Manager object the DataReaderSrc.
The package already contains one Connect Manager object:
Provider: .Net Providers/Odbc Data Provider System DSN
Hi all, I saw a couple of other posts here on this topic, but none quite got to my issue. I'm trying to add error output to a custom source component (not a script, a custom component). The samples all seem to deal with transform components, and my issues seem to be unique to source components.
I have the following code related to error handling ...
Public Overloads Overrides Sub ProvideComponentProperties()
...
Dim output As IDTSOutput90 = ComponentMetaData.OutputCollection.New
Dim errorOutput As IDTSOutput90 = ComponentMetaData.OutputCollection(ERRORCOLUMNNAME)
Dim errorColumn As IDTSOutputColumn90 = errorOutput.OutputColumnCollection.New
errorColumn.Name = outColumn.Name
errorColumn.SetDataTypeProperties(DataType.DT_I4, 0, 0, 0, 0) ... End Sub
The confusions I have are: a) the stock advanced properties editor (I haven't provided a custom one) doesn't seem to "realize" that I have an error output, so provides no method to configure. I am believing it would need to know which Output columns can have their error/truncation redirected. I'd have thought setting ErrorRowDisposition on my output column would have been enough to trigger this ?? b) since I don't have any means of configuring, not surprisingly, when I try to connect my error output, designer complains that, "Ths error output cannot receive any error rows. This occurs for several reasons: Input columns or output columns are not yet defined. Error handling is not supported by the component. Error handling is not configured for the component." c) UsesDispoistions would seem to be appropriate only for a transform component
Thanks for reading, and appreciate any help or pointers. Bill
after we've upgraded to SP2 my flat-file-source component hangs in the validation phase. normally at 50% or 66%. i see no activity what-so-ever cpu-wise/memory-wise. have no idea how to fix it.
(sorry if i am posting this twice, couldn't see my previous post)
Hello, I have a 'ForEach Loop Container' that does a select from a table and I use Variable Mappings to map each row set result to Package Variables in SSIS. This works fine. However, in the Data Flow, I have a Script component in which I need to access the values of those variables that have been set in the ForEach Loop Container. How do I do this?
Perhaps I'm on the wrong track but I guess I need to access the ADO Object Source variable set in the ForEach Loop Container? Through my own experimentation, I know that accessing the VariableDispenser collection only returns whatever default values that happen to be assigned to the variables in the SSIS GUI (not the values assigned during each iteration of the ForEach Loop).
I have created an SSIS On my PC, That extracts data out of Lotusnotes. When I run it manaully from Visual studion-execute package, it works just fine. However, when I go tO Management studio, chose the servername, then go to Stored Package-MSDB- And chose Packagename, and hit Run PKG from there, it gives me the error below. Server has 2005 AND IS WINDOWS 2003 OS.
The product level is insufficient for component "datareader source"
Can you tell me why the same pkg will work fine when executed from Visual studio-But when I go the run it from Storedpackages-MSDB-it fails.
I have a data flow that uses an OLEDB Source Component to read data from a table. The data access mode is SQL Command. The SQL Command is:
select lpartid, iCallNum, sql_uid_stamp from call where sql_uid_stamp not in (select sql_uid_stamp from import_callcompare)
I wanted to add additional clauses to the where clause.
The problem is that I want to add to this SQL Command the ability to have it use a package variable that at the time of the package execution uses the variable value.
The package variable is called [User::Date_BeginningYesterday]
select lpartid, iCallNum, sql_uid_stamp from call where sql_uid_stamp not in (select sql_uid_stamp from import_callcompare) and record_modified < [User::Date_BeginningYesterday]
I have looked at various forum message and been through the BOL but seem to missing something to make this work properly.
The article, is the closest I have (what I belive) come to finding a solution. I am sure the solution is so easy that it is staring me in the face and I just don't see it. Thank you for your assistance.
At our business we are getting a lot of PDF documents that are being hand keyed into a database. Has anyone heard ior know of a SSIS Data Flow Source component that I coud use to read thos documents into a data stream (?) and process?
I have created a dts (.dtsx file). which gets the data from my log file and insert into my sql 2005 table. In dts i am using 'Flat File Source' and 'OLE DB Destination' (becoz i need to acess my db remotely). When i execute this through 'SQL Server Business Intelligence Development Studio' it's working fine but when i execute this through my c# code, it throws me an error 'The product level is insufficient for component Flat File Source (1)'.
I have a flat file source in my data flow that is suppose to feed through a couple of columns to a script component. All of the columns have data but when I debug in my script component (with the aid of messageboxes) I can see that one of then is empty.
This is wrong because when I preview that data in the flat file source, I can see that the columns are all populated.
Has anyone ever encountered that a flat file source doesn't communicate with a script component properly? I mean it does pass through the data of all other columns except for one.
I have replaced the components in case it had become corrupt and I even rebuild the package but the problem still persists.
