Urgent. Output Columns Are Not Appearing When I Use OLEDB Data Source With An Oracle Stored Procedure In Dataflow Task

Nov 12, 2007

I am using execute sql task to run a stored procedure in oracle database which returns a resultset. This works. Now I need to send the ouput to a destination table in a sql database. Should I use for each loop to pick the resultset and insert it into the destination one by one (which I dont think is a great idea) or is there a better way to accomplish this task (in data flow task) ?

When I use dataflow task instead of execute sql task, the main issue is I am not able to see the output columns when I execute an oracle stored procedure, but when I see the preview I can see the resultset . But I can see the output columns for a sql server stored procedure.

Ho To Make Data Source Web Method Execute Once Per A Report?

Jan 11, 2007

My report works with XMLDP data provider and obtains source data as a
result of a web method call. This memthod returns all data necessary
for the report. Thus, all of about 20 report datasets query the same
web method with the same parameters and then select appropriate data
with different ElementPath expressions. It's so inefficient and
time-consuming! I cant have respective web method for every dataset.
How can I configure SSRS to call web method only once while the report
is executing? Or how can I leverage the performance at all?

Using A Sproc As A Source Within Dataflow

Dec 8, 2005

I was wondering what has worked for all of you in regards to using a sproc as a source within a dataflow.  I have had limited success doing this, but maybe there is a workaround I'm unaware of.  Basically, using a SQL command in an OLE DB Source, I run an EXEC statement that returns a resultset from a stored procedure.  I've noticed that depending on how the sproc is structured, I will either get metadata info in the columns tab of the OLE DB Source or not.  Without this metadata of course I can not link it with a destination, since the destination believes that no data is being returned, even if this is not the case.  This all seems to depend on the "final" select statement in the sproc being at the very top of the sproc.  If it is not at the top, the columns tab will not be populated.  Has anyone else had similar issues?  Is there a workaround other than populating a temp table outside of the dataflow?

ActiveDirectory As A Dataflow Source

Feb 27, 2008

Has anyone in here had luck using AD as a datasource? Big picture, we have an input file with unique identifiers (employee clock numbers) and I need to associate a clock number with an email address. The only place we have those two together is in Active Directory.

Currently, we have a lookup task with an OLE DB connection to our AD and a query that looks like



Code Snippet
SELECT mail, clockNumber
FROM 'LDAP://DC=company,DC=com'





I've mapped my input to the clockNumber in AD and all is well and good. I then go to thinking, perhaps it'd be better if I used that query as a source in an OLE DB component and used a Merge Join to make the link between the two. I paste that same query into a source component and boom




Code Snippet
TITLE: Microsoft Visual Studio
------------------------------
Error at Create extracts [OLE DB Source [1226]]: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x00000000.

------------------------------
ADDITIONAL INFORMATION:
Exception from HRESULT: 0xC0202009 (Microsoft.SqlServer.DTSPipelineWrap)




Is this just not something that a person can do or is there something I've set up incorrectly? I'd be lucky to be considered a novice with AD so I'm fine if someone has a better suggestion for retrieving this data, this was just something I'd cobbled together out of some forum postings.

Dataflow Tab:There Is No ODBC Source Option In The Toolbox

Feb 27, 2007

I need to extract data from tables in a database that I can only access via ODBC.

I have successfully created a connection in Connection Manager (ConnectionManagerType = ODBC) for this database.

However I€™m unable to add this connection as a Data Flow Source. There is no ODBC Source option in the Toolbox.

This is a major because we have been using the system dsn Microsoft Visual Foxpro Driver to access free table directory .dbf files under ODBC with DTS for years. To install a new Microsoft OLEDB driver for foxpro is out of the question on a production system as it would cost many thousands of dollars to go through our BAT testing process



How do I extract data from tables in a database via ODBC?

Thanks in advance

Hello All,





I am trying to convert an application created using DTS classes to SSIS object model. I have found following code in the application.



For x As Integer = 1 To mTask.Properties.Count




If mTask.Properties.Item(x).Name = "SourceConnectionID" Then




CnID = mTask.Properties.Item(x).Value

Exit For

End If

Next



For x As Integer = 1 To mPkg.DTSPackage.Connections.Count


If mPkg.DTSPackage.Connections.Item(x).ID = CnID Then

Next



Return mTask.Properties.Item("SourceObjectName").Value



How can I retrieve or Set "SourceConnectinId", "SourceObjectName" of a data flow task in SSIS



Please help me to solve this problem.

SSIS Dataflow OLEDB Source Issue With DB2 Connection.

Jun 23, 2006

Hi,

I have problem to extract data from DB2 table using SSIS dataflow task with OLEDB source selecting the data access mode with command. Here is the scenario.(Note:If I select the data access mode as a table then it works fine.)

If I use the data access mode as SQL Command then it is not working. i.e. the flow stays yellow in controlflow nothing happens in dataflow and I noticed the SQL dumper and proc completes. I couldn't find any log to verify the issue including the package execution results.Any of your thoughts will help me to resolve this issue.

Thanks..Mako

How Should I Change The Source File Name Every Time During Dataflow Task Using Ssis

Apr 4, 2008

Hi,
I am using SQL Server2005 for SSIS. I want to change the source connection dynamicaly evertime.
Let me clear, I have to extract some column from excel to MS-Access. I am using Data Flow Task and able to successfully complete the job. But problem is that, whenever a new file comes , i must have to reconfigure my Excel Source.
All the time column in file are same, so no need to worry about mapping but how can my package select a file automatically.
I have a directory, suppose "C:dpak". I should able to pick the filename and sheet name from this directory every time when my package will execute.

Enabling Expression Builder For Custom SSIS DataFlow Source Component

Mar 13, 2007

Hi,

I have implemented a custom source component that can be used as the data source in the Data Flow task.

I have also created a custom UI for this component by using the IDtsComponentUI .

But my component does not have the capability of setting the custom properties via the DTS Variables using the Expression Builder.

I have looked around for samples on how to do this, but I can only find samples of how to do this for custom Control Tasks, i.e. IDtsTaskUI.

My question is, How can implement the Expression Builder in my custom Source component + custom Source UI. Or do you know of any samples which I can look at.

Thank you,

Jameel.

Integration Services :: How To Change Dataflow Source Connection Based On File Extension

May 6, 2015

I have implemented a package to load multiple files to a destination. Since the source was a txt file, i have created as flat file source. However now we are getting files in excel format as well.

Is there anyway the source gets changed dynamically based on the file extension, output of the foreach file enumerator? I can think one solution to have 2 dataflow tasks based on precedence constraining and expression one is for .txt and other one is for .xls.

SSIS XML Source Adapter Can't Make XSD Location An Expression

Nov 21, 2007

I am using the "XML Source Adapter" in an SSIS package.
I notice that although you can specify the XML filename as an expression, the XSD appears to have to be a fixed file path.
This is a problem for me since the path for the XSD is different in my development than it will be in production (in production it's on drive E:, which I don't have).

I'd like to have the file location specified in the config file, but since I can't make it an expression how can I do that?

Also, since they don't have Connection Managers I can't switch DelayValidation on.

Thanks.

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

Cannot Create A Connection To Data Source 'data Source Name'

Dec 11, 2007

Today I was making a few reports.
When I tested the reports in Visual Studio, they worked great: I got the expected result.
But when I deployed the reports to our reportserver the problem started.
When I click on the directory in which my reports are deployed, I got my 4 reports.
Till now everything worked correct.
But when I click on a report to view the results it went wrong.
I got an error:
"Cannot create a connection to data source 'Live'"
(Live is the name of our data source).

We are using the Windows Logons and I am sure that I have all the rights on the server, I gave myself 'sysadmin' rights, so it should work.
I also have tried it with all the roles assigned on my account, but then it still won't work.

When I modify the data source, and set it to another server en database it works.
The datasource 'Live' exists on a x64 MsSQL server, en the other datasource is on a x86 MsSQL server.
Maybe that is the problem?

Can someone tell me what is wrong?

Loading Data Using Ole Db Source With Input Source Being A View

Dec 13, 2007

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?

DataFlow Problem Moving Data From SQLServer To Oracle

Feb 26, 2008

Hi pals,

I have a small problem in Datflow task.

Basically i am having two tables(similar to my current requirement). One in sql server 2005 and another in ORacle

SQL Table
create table t1
( c1 numeric(6),
c2 numeric(6),
c3 varchar(50),
year numeric(4),
district varchar(10)
)


Oracle Table
create table app_t1
( c1 number(6),
c2 number(6),
c3 varchar2(50),
year number(4),
district varchar2(10),
constraint cpk primary key (c1,year,district)
)

I am using 2 global variable for passing values to c4 and c5 columns in oracle table.
The variable names are g_year and g_district.
i am using a dataflow task to move data from sql server 2005 to oracle 9i database
I am able to load the data from sql server to oracle.
Till here it is fine.
But the requirement is if i get same data i.e same dist and same year then we need to delete the data
in oracle table as
"delete from app_t1 where year = ? and district = ?"

Immediately i need to issue a commit statement.

and thereafter i need to load data for that particular district and year.


To accomplish this requirement i am using ,

An Execute SQL Task to Delete the data from ORacle
An Execute SQL Task to COMMIT the transaction
Finally i am loading data from sqlserver to oracle using a dataflow task.

But i am getting an error as
"Value violated the integrity constraints for a column or table.".

I think the deletion operation is not getting committed.

So what i did was i connected to oracle and deleted the data using above DELETE statement
and again come back to SSIS package and ran the package once again, this time it is successfull.

Why is it so. Any thoughts on this?

Any help would be greatly appreciated.
Thanks!

Dynamic Excel Destination Depend On Dataflow Data

Jul 10, 2007

I created a data flow with complaicated SQL. There is "type" field in the output column.

I would like to created excel files for each "type" value

E.g. If there is 3 "type" values (A, B, C), I would like to create 3 excel files to store type A, type B, and type C data respectively.



Since the number of possibe value of "type" field is various, how can I create the xls destination dynamic and move the correct type to the corresponding excel file?



The conditional split has fixed conditions, it is not suitable for by dynamic number of value

For Loop condition is not a good choice because I need to run the complicated SQL for many time.



Thanks.

Adding Numeric Data To A Dataflow In A Scriptcomponent-&&> Invalid Number In OLE Db Command Transformation

Jun 9, 2006

Hi there,

This seems a bug to me. Or does anyone has a logical explanation that escapes me?

When in SSIS Designer Version 9.00.1399.00 I add output columns (numeric 4,0 ) to a scriptcomponent and fill them with valid numeric data in thescript I get a database error 'invalid number' when I use these columns in an OLE db Command-transformation . This errormessage disappears when I replaces those columns by a dataconversion to the datatype they originally have.

Derived Column Name Derived Column Expression

STATUS_DEF Replace 'STATUS_DEF' (DT_NUMERIC,4,0)STATUS_DEF

Maybethis info is usefull for somebody else who can't figure out wathever he's doing wrong.

Integration Services :: Dataflow Task Read CSV File And Insert Data To Table

Apr 29, 2015

I've a dataflow task on For Each Loop container at control flow of SSIS package. This For Each Loop container reads the CSV files from the specified location one by one, and populates a variable with current file name. Note, the tables where I would like to push the data from each CSV file are also having the same names as CSV file names.On the dataflow task, I've Flat File component as a source, this component uses the above variable to read the data of a particular file.

Now, here my question comes, how can I move the data to destination, SQL table, using the same variable name?I've tried to setup the OLE DB destination component dynamically but it executes well only for first time. It does not change the mappings as per the columns of the second CSV file. There're around 50 CSV files, each has different set off columns in it. These files needs to be migrated to SQL tables using the optimum way.

Which is the best way to setup the Dataflow task for this requirement?Also, I cannot use Bulk insert task here as we would like to keep a log of corrupted rows.
