Using An ODBC Data Source In A Data Flow

Oct 2, 2006

Okay, this should be really simple but I don't get it. How do I use an ODBC data source in an SSIS data flow task? When I look at Data Flow Sources I see the following options:

Pointer

DataReader Source

Excel Source

Flat File Source

OLE DB Source

Raw File Source

XML Source

Which one do I use if I need to get the data from a connection manager that is ODBC based? The IBM OLEDB driver for the AS400 doesn't work correctly so I HAVE to use an ODBC driver to connect to an AS400 data source.

Thanks in advance for any info.

How Do I Add An ODBC Connection Data Source As A Data Flow Source

Mar 2, 2007

I have set up a new connection as a connection from data source, but I cannot see how to use this connection to create my Data Flow Source. I have tried using an OLE DB connection, but this is painfully slow! The process of loading 10,000 rows takes 14 - 15 minutes. The same process in Access using SQL on a linked table via DSN takes 45 seconds.

Have I missed something in my set up of the OLE DB source / connection? Will a DSN source be faster?

Thanks in advance

Set The Data Source Of Data Flow From External Application (C#)

Jan 11, 2006

I am new to SSIS programming, so bear with me if my question seems naive to you gurus. I have a situation that needs to set the data source for a data flow from external .NET application ('external' means that the application will run on different process than the SSIS). I am trying to set the data source on which the data flow works from my C# application in a DataSet format. Ideal solution is not to save the DataSet to any file on harddisk (I know that will work, but has the overhead of writing, reading and managing the temp file). What I want to achive is that the business logic of picking data for SSIS Data Flow to process is controlled inside my C# application, the Data Flow just does what it does best - Transformation. Have any of you successfully done this before?. Thanks!

Data Reader Source In Data Flow Problem

Jul 18, 2006

hi all,

i have a package in ssis that needs to deliver data from outside servers with odbc connection. i have desined the package with dataflow object that includes inside a datareader source. the data reader source connect via ado.net odbc connection to the ouside servers and makes a query like: select * from x where y=? and then i pass the data to my sql server. my question is like the following:

how do i config the datasource reader or the dataflow so it will recognize an input value to my above query? i.e for example:

select * from x where y=5 (5 is a global variable that i have inside the package). i did not see anywhere where can i do it.

please help,

Truncation Of String Data With Data Reader Source Connecting To ODBC DSN

Mar 18, 2007

A data reader is using a connection manager to connect to an ODBC System DSN . A query in the SqlCommand property is provided. Data is being truncated in the only string column . The data type in data reader output-->external columns shows as Unicode string [DT_WSTR] Length 7.

The truncated output in a text file is the first 3 characters from left to right . Changing the column order has no effect.



A linked server was created in SQL Server Management Studio to test the ODBC System DSN using the following:

EXEC sp_addlinkedserver
@server = 'server_name',
@srvproduct = '',
@provider = 'MSDASQL',
@datasrc = 'odbc_dsn_name'

Data returned using "OPENQUERY" does not truncate the string column indicating that the ODBC Driver returns data as expected with sql 2005, but not with the Data Reader.

Any assistance would be appreciated.

Thanks,

Using A Recordset Source In A Data Flow

May 17, 2007

I have been using a recordset destination in a data flow where I need to perform some complex manipulation on a dataset, including combining some information from a web service and updating records that already exist, vs. inserting them.

I have a script task that modifies the dataset as needed, and then saves it back to the variable it came from.

However, when it comes time to write the data to the database, I couldn't find an appropriate tool - there's no "recordset source" object in the data flow task, and use of a "for each" loop with a sql call to a stored proc takes 20 minutes for a few thousand rows.

The best way I could find around this was as follows:



Call the .NET ".GetXML" method on the dataset and put the resulting XML data into a string variable
Generate an XSD for that XML (it comes out like <NewDataSet><Table1>...)
Use an XML source in the data flow task.This works, and the same data insert that took 20 minutes via the loop / stored procs now takes under 10 seconds.

It seems horribly inefficient to have to do this - there should be a way to just dump my dataset back into a table natively without all that extra stuff.

Anyone done anything simillar?

Slow OLEDB Source In Data Flow

Slow OLEDB Source in Data Flow

Hi All,

I have a simple data flow task, composed of only an OLEDB Source, a Conditional Split, and two Execute SQL statements (both insert statements, one after the other). When I run my package in Visual Studio for debugging, I noticed that after executing around ~9800 in the first and another ~9800 records in the second insert statements, the OLEDB Source will take around 3 or 4 minutes to fetch another set of ~9800 records. I have set the DefaultBufferMaxRows property of the Data Flow to 10000. My query to retrieve those 700,000 records runs for about 2-3 mins to finish (which I think should be decent enough). Is this an expected behavior of SSIS? The expected number of records to be retrieved is 700,000, and it takes forever to finish the transfer of these records. Please help

Data Flow Source Script Component

Dec 3, 2007

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?

Using A Stored Procedure As A Data Flow Source

Dec 11, 2007



Simple question - can I use an external stored procedure for my data flow source. I assume that I can use the OLEDB connection and go from there?

Can I use SQL command and do exec sp_thisprocedure?

Thanks for the information.

Data Flow Task - OLEDB Source / Destination

Nov 9, 2006

Hi

Inside a data flow task, i have a oledb source and destination. In my situation, I need to pull data from a table in the source, but also hard code some columns myself, which means my source is a blend of data from table, hard coded data, which will then have to be mapped to columns in oledb destination. Does anyone which option to choose in the oledb source dropdown for the data access mode. Keep in mind, i do need to run a a select query, as well as get data from a table. Is it possible to use multiple oledb sources and connect to one destination, because that is really what intend to do here. I am not sure how it will work, or even if its possible. Basically my source access mode needs to be a blend of sql command and table columns, how would that be implemented? Any help or advice is appreciated.

Data Flow Source For MS Access In SSIS Package

Jul 26, 2006

Hi all...

I'm creating a SSIS in the designer view of SQL Server BI Dev. Studio (SQL Server 2005)

I need to import a whole table from MS Access into my local SQL Server.(this task will be performed weekly, so once working I'll schedule a job for it)

I've created a 'FILE' connection to MS Access in the 'Connection Managers'.

When I'm on the 'Data Flow' tab I can't find a Data Flow Item to use as a MS Access connection.
(available on the 'Data Flow Sources' are only: DataReader, Excel, Flat File, OLE DB, Raw File and XML Sources)

What am I doing wrong/missing?

Thanks for your help.

Data Flow Source That Will Take A String Variable With Csv Structure?

Dec 21, 2006

I am able to use a custom script task to receive a MSMQ package and save the package contents to a flat file.

I can also use the bulk load task to push the flat file contents into a SQL table.

However, I would like to save the package contents to a variable (done, it works), and then pass that string variable to a data flow task for SQL upload. In other words, I don't see any reason to persist the msmq package contents to disk.

My question is: Which data flow source can I use that will accept a string variable? The string variable will then need to be processed with bulk load or an execute sql task.

Btw, the content of the string variable is a csv style string:

"01001","11/21/2006",15
"01001","11/21/2006",1
"01001","11/21/2006",25
"01001","11/21/2006",3


Thanks,

Basic Text File Data Flow Source

Jun 7, 2007

In DTS 2000 I had a situation where I had a text file as input source and text file as output source. On migrating the package to 2005 it puts a wrapper around it which executes it as a 2000 package, the rest of the tasks are neatly converted to 2005 style tasks. I presume this to mean that this will not be supported through to the next version, and there is no direct equivalent in 2005.



My question is how do I import a non-flat file source which has different numbers of columns per line. I did ,somehow, manage to do this with 2000 but cannot seem to get anywhere with 2005.



The flat file source seems to be expecting a common number of columns and just can't seem to cope with no column delimiters on some lines. If anybody knows different I would be glad to hear about it.



Raw data is not helpful to me as only works with a specific raw type (apparently)



Went onto Bulk Insert Task but got this message



[Bulk Insert Task] Error: An error occurred with the following error message: "Cannot fetch a row from OLE DB provider "BULK" for linked server "(null)".The OLE DB provider "BULK" for linked server "(null)" reported an error. The provider did not give any information about the error.Bulk load: An unexpected end of file was encountered in the data file.".



Have already browsed with this on web but only find comments about changing timeout setting.



Can find timeout settings in DataFlow source and DataFlow destinations but not in Bulk Insert Task.



As you can see this is a long and protracted question.



If the answer is simple I apologise if not blame Microsoft. Other than that have found SSIS has some nice improvements, apart from the odd vague error message I keep coming across.

Data Source ODBC

Dec 8, 2007

Hi all,

I am new to SQL Server. I have some basic questions.

I have installed SQL Server Developer Edition on a Windows XP Media center edition. The installation is successful. Now I am trying to create an ODBC, but I there are some options which I am not quite sure about.

e.g.

1. How SQL Server verify the authenticity of the login ID?
A. Windows NT....
B. SQL Server....

Client Configuration:
Server alias: ???
Named Pipes: What should be the values of [pipe name]?

or should i choose other options?....


And I when I use Query Analyzer to connect to Server, the authentication fails..

Can some one point me to the right direction, or if there's some documentation on this subject, that would be very much appreciated.

Thanks in advance.

I set up the ODBC DSN, and my SQL Server Data Connection, and can browse the tables in the Server Explorer. However with regards to my SSIS package, I'm not sure whether to use an OLE DB Source or Data Reader Source. I have futzed with both of them but haven't had any luck at seeing the tables. Can someone please give me some tips.

Query Results SSIS Data Flow Source Adapter

Jun 1, 2006

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.

Thanks,
Gaurav

Fail To Execute Store Procedure In OLD DB Source In Data Flow

Jun 20, 2006

Hi. I am trying to extract the data returned from a store procedure to a flat file. However, it fail to execute this package in the OLE DB Source.
I select the SQL Command in the Data Access Mode, then use:

USE [SecurityMaster]
EXEC [dbo].[smf_ListEquity]

It runs ok in the Preview, but not in the Run. Then the system returns during executing the package:

Error: 0xC02092B4 at Load TickerList, OLE DB Source [510]: A rowset based on the SQL command was not returned by the OLE DB provider.
Error: 0xC004701A at Load TickerList, DTS.Pipeline: component "OLE DB Source" (510) failed the pre-execute phase and returned error code 0xC02092B4.

Please give me some helps. Thanks.

Parameters In Data Flow Task With Oracle Database Source

Jul 9, 2006

In many DTS packages I have used parameterised queries for incremental loads from Oracle database sources using the Microsoft ODBC Driver for Oracle.

Now I want to migrate these packages to SSIS, but the OLE DB connection for Oracle does not support parameters.

I cannot use the "SQL command from variable" data access mode because of the 4000 character limitation on the length of string variables and expressions.

Am I missing an obvious workaround?

ODBC Data Source Error

Apr 20, 2006

As other contributors, all I am trying to do is import data from an ODBC source (spelled 'non-Microsoft data source') into a SQL 2005 table. I can easily do this in SQL 2000 with DTS, but when I use the same DSN in VS 2005 it doesn't work.

I created an integration project, and made a connection in Connection Manager to the DSN and clicked Test Connection. It succeeded, or so it claimed.

Click OK and drag a DataReader Source onto the Data Flow surface Doubleclick it and select the connection manager per above. Note the error: Error at Data Flow Task [DataReader Source[50]]: Cannot acquire a managed connection from the run-time connection manager.

What does that mean? More to the point, how to fix it?

Flat File Data Flow Source Returning Limited Rows

Jan 14, 2008



All,
I'm having an issue with the Flat File Data Flow Source returning only a limited set of the rows that are in the flat file. Basically, I connect to the flat file fine, it goes to retrieve the data (tab delimited file) and only returns 190 of 392 rows. Is there a limitation on the # of rows this data flow source can retrieve or something? I've look all through the settings and properties of the task as well as the connection manager and nothing is obvious as to what is causing this. Hopefully someone ou tthere has run into this before and can help me retrieve all rows. Thanks in advance!
