Advanced Editor For DataReader Source / SQLServer 2005
May 11, 2007
I want to import data from a remote MySql Database
So, I created an New Connection (ADO.Net), connection Test is successful but when I try to set the sql string in the advanced editor i get the following error:
Error at Data Flow Task [DataReader Source [2182]]: System.Data.Odbc.OdbcExeption: ERROR [HY010][MySQL][ODBC 3.51 Driver][mysqld-4.1.10a]

bei Microsoft.SqlServer.Dts.Pipeline.ManagedComponentHost.ReinitializeMetaData(IDTSManagedComponentWrapper90 wrapper)
the sql string is very simple, this should not be the problem:
SELECT Objektnr FROM m02a_tblObjektstamm
Thank you very much for your support

HI!
as far as I know from docs and forum datareader is for .NET data in memory. So if a use a complex dataflow to build up some data and want to use this in other dataflow componens - could i use data datareader source in the fist dataflow and then use a datareader souce in the second dataflow do read the inmemoty data from fist transform to do fursther cals ?
how to pass in memory data from one dataflow to the next one (i do not want to rebuild the logic in each dataflow to build up data data ?
Is there a way to do this ? and is the datareader the proper component ? (because its the one and only inmemory i guess, utherwise i need to write to temp table and read from temp table in next step) (I have only found examples fro .NET VB or C# programms to read a datareader, but how to do this in SSIS directly in the next dataflow?
THANKS, HANNES

Hi,
I've developed a couple of components now and I know I've seen this problem before but I can't remember how to solve it. My component is built, it has it's own (blank at the moment) UI and it seems to work fine except that there is no right click option to look at the advanced editor. The code is almost identical to another component I wrote that works just fine.
Any ideas anyone?
Thanks
Charlie.

Hello,
I'm working on a custom dataflow destination component. It makes use of the External Metadata Collection. I also use Custom Properties with the external metadata collection.
When I open the destination component using the Advanced Editor, and select an External Metadata Collection and change the Custom Property it always changes back to the original value.
Additionally the method SetExternalMetadataColumnProperty never gets called.
Here is a little Test Component that surfaces the problem:
[DtsPipelineComponent(ComponentType=ComponentType.DestinationAdapter, DisplayName="Test Destination")]
public class Class1 : PipelineComponent
{
public override void ProvideComponentProperties()
{
base.ProvideComponentProperties();
ComponentMetaData.InputCollection.RemoveAll();
IDTSInput90 input = ComponentMetaData.InputCollection.New();
input.Name = "Name";
input.ExternalMetadataColumnCollection.IsUsed = true;
IDTSExternalMetadataColumn90 ext = input.ExternalMetadataColumnCollection.New();
ext.Name = "ExtName";
IDTSCustomProperty90 customProp = ext.CustomPropertyCollection.New();
customProp.Name = "Custom Property";
customProp.Value = "Hallo";
}
public override IDTSCustomProperty90 SetExternalMetadataColumnProperty(int iID, int iExternalMetadataColumnID, string strPropertyName, object oValue)
{
return base.SetExternalMetadataColumnProperty(iID, iExternalMetadataColumnID, strPropertyName, oValue);
}
}
Any ideas how to make that work?

This one has set me back many, many hours on this project; it's about got me ready to dump SSIS & just roll a custom .NET solution in C#.
I need to create import packages for quite a few very wide flat files (130 - 180+ columns, not my design). Many of these columns have data > 50 characters long.
I change column widths on the data flow source using the Advanced Editor, via Input and Output Properties ==> Flat File Source Output ==> External Columns.
About 50% of the time, the changes vanish after clicking OK to dismiss the Advanced Editor. There is no warning message or output announcing that the editor failed to persist its changes, or that it set some columns' properties back to the defaults, or why. The column's widths just silently revert back to 50.
If the cause and resolution aren't known, does anyone know of a way to accomplish any of the following workarounds?
Create a data source connection by importing an external text schema defining the flat file's column names, data types and sizes, or
Change a property on multiple source columns en-masse, or...
Get at a text version of the file containing the Data Flow Component's definition, so we can edit wide import schemas without racking up thousands of mouse-clicks?Thanks! A virtual cheeseburger to anyone with answers.

hi,
I am using SSIS to extract data from sql server and import into MDB file. In
the process, under data flow task, I have used OLE DB Source Editor as source. Here
i have choosen SQL Command as mode of data population. In the box below i
have typed the following statements.
"Exec Site_Address"
I have used many temperory tables in this procedure.
When i run this procedure in the query analyzer window i get the desired data which has to be imported to an MDB. After typing the above statements and when i
click the button preview i can see the data. But when i click the
Columns.... i dont see anything there. I am unable to see any columns there.
This is getting to my nerves because, when i use OLE DB as Destination i am
unable to map the columns and i get an error.
I dont know how to solve this problem. cannot we map columns in temp tables .... or wat is it ??
Please help me to find a solution.
I will also paste the procedure code that i have used.
Create procedure Site_Address
as
begin
create table #Data_For_Site_Address_Table
(
unitid varchar(20),
city varchar(50),
cust_num varchar(40),

Hi All,
I want to connect to SQLExpress database on the network. I can do so using code but I want to use the Data Source Configuration Wizard. It seems this only works for local instances of SQL server. Is this true?
I can connect just fine to the database on the network using Microsoft SQL Server Management Studio Express...for what this is worth.
I have tried to map a drive to the SQL server machine and pick the mdf file but I get the error msg of network path is not supported for database files....I have turned on allow remote connections, allow tcp/ip, named pipes, added sqlserv.exe and sqlbrowser.exe to my firewall exceptions ect..
I want to be able to use Table Adapters, SqlDataAdapters ect. After reading numerous forum questions/ kb articles this seems to be a common problem. I am on the verge of just saying forget it and use MS Access instead.
Thanks in advance!

Hello,
I have a DataReader souce configured to an ADO.NET connection manager that uses a .NET ODBC Data Provider. The DSN configured in the connection manager uses the IBM DB2 ODBC Driver.
I have a package variable, the value of which I want to use in the WHERE clause of the query contained in the Data Reader source. The query is as follows:
SELECT
T1."IRK_ACCT_CD",
T1."IRK_COMPANY_NBR",
T1."IRK_ACCT_NAME",
T1."IRK_ADDRESS_1",
T1."IRK_ADDRESS_2",
T1."IRK_ADDRESS_3",
T1."IRK_STATE_CD",
T1."IRK_POSTAL_CD",
T1."IRK_AR_TYPE",
T2."RK502_ITEM_RE_NO",
T2."RK502_TRANS_CD",
T2."RK502_TRANS_TYPE",
T2."RK502_ITEM_AMT",
T2."RK502_ITEM_DT",
T2."RK502_PURCH_ORD_NO",
T2."RK502_GL_EFF"
FROM "CBDBOW"."IRK_RECORD" T1, "CBDBOW"."RK502_OPEN_ITEMS" T2
WHERE
T1."IRK_COMPANY_NBR" = T2."RK502_COMP_NO"
AND
T1."IRK_ACCT_NUMBER" = T2."RK502_ACCT_NO"
AND
T2."RK502_ITEM_DT" < ?
I'm not very sure as to how to map the package variable this way. I think for ODBC parameters, I need to represent the parameter with a question mark.
What else do I need to do to set this up?
Thank you for your help!

I have configured my DataReader to use an ADO.net (ODBC) connectivity (entered Select * from AMPFM) in Sqlcommand and can see my database columns listed in the Advanced Editor / Column mappings window. My process needs to perform a straight column to column population from AMPFM table into my dbo.visitfinancials table. How do I point the output to the above table?

I have a problem with DataReaderSource.
I'm trying to get data from Notes table. I created a Connection manager
and the connection was successful. The SQLCommand in "Component properties"
tab is a simple "select * from <table_name>". When I switch to the
"Column mappings" tab, only the first column from the table is displayed.
Pressing the "Reftesh" button resulst in the following error:
Error at Data Flow Task {DTS.Pipeline]: The "output column <column_name> has a length that is not valid.
The length must be between 0 and 4000.
When I go to the "Input and Output Properties" tab, the DataType for the output column is not populated
and the error message "Error in Data Flow Task [DTS.Pipeline]: The output column <column_name> had an
invalid datatype (0) set."
The DataType property is not populated at all. Changing the data type to DT_STR results in error:
"Property value is not valid". Details: Error at Data Flow Task [DataReader Source]:
The data type of output columns on the component "DataReader Source" cannot be changed".
I read on a previous post to explicitly convert field , and tried to explicitly covnert the dataype on the field
in my query (ex. select convert(varchar(50) from fieldname)
It then gives foll err:
ERROR [42000] [Lotus][ODBC Lotus Notes]Incorect syntax near ','
[Lotus][ODBC Lotus Notes]Name, constant or expression expected.
Any idea on how to resolve this?

Hi all,
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.

Hi,
I am running an MDX query in SSIS but I don't know what is the best way of doing this, performance wise.
I know I can run the MDX query through an openquery in the OLEDB, and also run it through a Datareader, no openquery needed.
I know the datareader is slower in a normal basis due to .Net, but in this case the OLEDB is running an open query to a linked server which won't be fast like running a regular SQL.
If anyone knows which of this two run faster in this scenario I'll appretiate if you let me know.

Greetings my SSIS friends,
Apologies for asking a similar question again but I am still non the wiser with this problem!
Let me explain to you my situation and the method I've adopted to try and solve it.
I have some source data residing in a SQL Server 6.5 database. The source data consists of a single table. For this example I will assume that my table contains only 2 columns, an ID column called result_ID and a Result_Name.
The idea is to retrieve new data each time the package is run. We will know this because the result_IDs in the source table will be greater than the maximum result_ID in my destination table . The way the package should work is like this :
1) Retrieve maximum result_ID from destination table
2) retrieve data from source table where result_ID > maximum result_ID from destination table.
My package consists of a
1) SQL Query Task which retrieves the maximum result_ID and places it in a user variable (type Int32).
2) A Data flow task with a Datareader source adapter which uses an expression to retrieve the data. My expression looks like this : "select * from result where result_id > " + (dt_str, 10, 1252) @[User::max_result_id]
When I run my package the first time all the rows are retrieved (as my destination table is empty to begin with). BUT when I run it the second time the same thing happens again!! All rows are retrieved.
I placed a breakpoint at the point where the variable gets populated with the maximum result_ID and true enough, the variable gets populated with the correct result_ID BUT then that variable gets reset to 0 in my expression!
This problem is driving me crazy! Has anybody out there experienced this kind of problem before?! What are the ways to solve it?!
Thanks for your help in advance.

I get an error at the end of a 47 million row job when I use the datareader source. It goes through all the records and then the package fails. The error (DataReader Source [1]] Error: System.NullReferenceException: Object reference not set to an instance of an object. ) occurs at the datareader source. I suspect it's because my record set returns a null value at some point. Any ideas?

Is there a way to control the types for output columns of a DataReader Source? It appears that any System.String will always come out as DT_WSTR. As I have my own managed provider, and I know what went in, I can say that really it should be DT_STR. The GetSchemaTable call from my provider will always say System.String as it does not have much choice, but GetSchemaTable does contain a ProviderType which is different for my DT_STR vs DT_WSTR, or rather when I want each. I think something like MappingFiles as used by the Wizard would work, but can I do anything today?

Dear All,
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.

i have a data flow configured to use a ole db source. the ole db source uses an ole db connection manager pointing to the adventureworks db which suceeded when i tested its connection. the data access mode of the ole db source is "sql command". below is the sql command text:
SELECT SpecialOfferID, Description
DiscountPct, Type, Category, StartDate,
EndDate, MinQty, MaxQty, ModifiedDate
FROM Sales.SpecialOffer
WHERE ModifiedDate >= ? AND ModifiedDate < ?
this query uses 2 paramaters, each of which is mapped to a datetime variable which falls with the range of the ModifiedDate column as follows:
Parameter0: User::ExtractStartDate
Parameter1: User::ExtractStopDate
ExtractStartDate is set to 7/1/2001 and ExtractStopDate is set to 3/31/2004. however, i get the following error when i press the preview button in the ole db source editor: "there was an error displaying the preview. additional information: no value given for one or more required parameters (microsoft sql native client)".
as far as i can tell, i have the ole db source configured correctly. thus, i can't figure out why this error is being generated. has anyone else experienced this issue? if so, were you able to resolve it? is this a bug?
thanks in advance.

I am trying to migrate data from MySQL 5.0 to SQL Server 2005. The MySQL database has a table which stores the profile description in different languages like (Arabic, Spanish etc). I use MySQL ODBC 5.1 driver for creating the ODBC connection and creating a ADO connection in SSIS using that ODBC. The datareader source connection is set to this ADO connection.
When I view the properties of columns in Datareader source it shows as Unicode, which is good. But when I migrtae to SQL Server 2005 I get junk data instead of the data in Arabic, Spanish etc.
Am I missing something or is there any other alternative to do the data transfer correctly?

Hi,
I am trying to use the DataReader Source to import a table from a PostgresSQL database into a new table in SQL 2005 database. It works for all tables except one, which has over 80,000 records with long text columns. When I limit the import to fraction of records (3,000 to 4,000 records) it works fine but when I try to get all it generates the following errors:

I'm attempting to iterate package components of a package created in the SSIS designer, but have run into a problem identifying the DataReader Source managed component.
For instance, if iterating the dataflow task components like so:
Application app = new Application();
MainPipe pipe = taskHost.InnerObject as MainPipe;
foreach (IDTSComponentMetaData90 component in pipe.ComponentMetaDataCollection)
{
if (component.ComponentClassID == app.PiplineComponentInfos["DataReader Source"].ID)
{
// THIS IS NEVER REACHED
}
}
The ComponentClassID of the component is a GUID, but the PipelineComponentInfo.ID AND PipelineComponentInfo.CreationName are both the fully qualified assembly name of the data reader source adapter, which is:
"Microsoft.SqlServer.Dts.Pipeline.DataReaderSourceAdapter, Microsoft.SqlServer.ADONETSrc, Version=9.0.242.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"
From reading another post i attempted to get the ProgID of the component from the class ID (ole32 ProgIDfromCLSID) but that only yields a ProgID of DTS.ManagedComponentWrapper.1
How can I properly identify this type of dataflow component?
I am running SQL Server SP2 (Developer Edition) on XP Pro SP2.

Hi,
I am trying to import data from Oracle RDB into SQL Server 2005 using SSIS. Created a ODBC data source to connect to Oracle and used DataReader Source component and ADO.net to connect to the ODBC data source.
Under the Component properties tab, the SQL Command looks something like this.
Select ID, ADDRESS, REVISED from ADDRESS
The data type for the source columns are Integer, Varchar(30) and DATE VMS.
Now when I look at the Input and Output properties window,
The External columns has the following data types.
ID - four-byte signed integer [DT_I4]
ADDRESS - Unicode string [DT_WSTR], length = 0
REVISED - database timestamp [DT_DBTIMESTAMP]
The Output columns has the following data types
ID - four-byte signed integer [DT_I4]
ADDRESS - Unicode string [DT_WSTR], length = 0
REVISED - database timestamp [DT_DBTIMESTAMP]
When I tried to change the length of the ADDRESS on the output column, I get the following error.
Error at Data Flow Task [DataReader Source [1]]: The data type of output columns on the component "DataReader Source" (1) cannot be changed.
Error at Data Flow Task [DataReader Source [1]]: System.Runtime.InteropServices.COMException (0xC020837D)
at Microsoft.SqlServer.Dts.Pipeline.DataReaderSourceAdapter.SetOutputColumnDataTypeProperties(Int32 iOutputID, Int32 iOutputColumnID, DataType eDataType, Int32 iLength, Int32 iPrecision, Int32 iScale, Int32 iCodePage)
at Microsoft.SqlServer.Dts.Pipeline.ManagedComponentHost.HostSetOutputColumnDataTypeProperties(IDTSManagedComponentWrapper90 wrapper, Int32 iOutputID, Int32 iOutputColumnID, DataType eDataType, Int32 iLength, Int32 iPrecision, Int32 iScale, Int32 iCodePage)
Is this the default length for the Unicode string type. I was not able to load the ADDRESS column as it gets truncated before I load it into destination. Even if I use Derived or Data Conversion transformation, the ADDRESS is getting truncated before it reaches this transformation.
Any thoughts.
Thanks,

Synopsis:
Attempting to create a data flow task to copy data from AS/400 (DB2) to SQL2005, using an existing System DSN ODBC connection defined on the SQL2005 host.
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:
Name=IDbConnection
Connection Manager=blank
Description=Managed connection manager
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
Test Connection operation succeeds
Any help would be appreciated.

I am storing a date value in a user variable(Date) I fill with a SQL Task and then want to use the value in the sqlcommand I use in the Datareader Source. It won't let me use the @variablename in the sql command.
Can anyone help with some advice on how I can make this work?
Appreciate any help I can get.
Thank you

Hi
I have an integration services script that was working ok until a recent database upgrade. When I run the script in gui debug mode it behaves as follows. The data flow reads in data from an oracle server table VALNREQ & then uses it to populate a sqlserver table (with a little manipulation of the fields in between). For some reason although it populates the destination table with the correct number of rows (& the data looks ok) it errors out with the messages listed below. The DataReader Source dataflow source box turns red & all the other boxes turn green including the destination one. I have run out of ideas ... any suggestions? Have I inadvertently changed a property without noticing? I can't see anything obvious & the input data itself looks clean enough.
Any pointers in the right direction would be great, thanks. I've been thrown in at the deep end with this s/w so I imagine there are a number of large gaps in my knowledge so apologies if there is a simple solution to this.
