While trying to code in VS 2019 (making utility to select data from Oracle DB) I got stuck.
I created DataSet with TableAdapter to it Pic0
In a query I must enter value for APPLICATION_NUMBER field, and when I "Execute Query" everything works fine and I get result (see Pic1)Pic1
But when I try to "Preview Data", I got error "ORA-01008: not all variables bound"
(see Pic2)
Just for info: it is Oracle 9i I am trying to connect to, I am using .NET Framework Data Provider for OLE DB because if I use .NET Framework Data Provider for Oracle it says "Connections to this server version are no longer supported".
Would appreciate much any useful info.
I tried to replace :PARAM2 with '&PARAM2' but with no luck.

I created an SSIS package to copy data from one Oracle table to another Oracle table. Each table is in a different database.
I'm getting this error for every single column of the source table:
ERROR [HY010] [Oracle][ODBC]Function sequence error
This is the screenshot.
I have no idea what this means. I've also researched but I haven't seen anything that has helped me.
How can I fix this? I did read that an alternative is to create a linked server.
I wanted to add that the ODBC driver was created with a relatively recent Oracle 12 driver, so I'm not sure why VARCHAR2 columns would not be supported.
Also wanted to point out that the Windows server where the Oracle DB is 64-bit (Windows Server 2008) and Visual Studio 2008 (where the SSIS package is created) is 32-bit. That's why the driver has "_32" at the end.
Based on the following documentation:
The error occurs when ODBC functions are called out of the order required by the ODBC Specification.
The error can also occur if an ODBC function call returns an error and the application continues making ODBC calls that require the previous ODBC call to succeed.
I think you should check that all columns data types are supported by the ODBC driver.

You can refer to the following link to learn more about supported data types:

Note that in the link above they mentioned that:
If a table contains a column whose data type is not supported by Oracle Database Gateway for ODBC, the column information is not returned to the Oracle database.
Afternoon Folks,
We are using Visual Studio 2013 and have an SSIS package that we are creating. We have a simple Data Flow Task that essentially takes some data from SQL and Pushes through to an Access Database. It has three DFD flow items:
I have a OLE DB Source (obtains the SQL via a select statement) --> Data Conversion (Convert SQL Data Types to Access) --> OLE DB Destination (Access Database)
The steps selecting the SQL and converting it works fine.
The issue we have is the SQL command that we are using to update the Access 2010 database.
We have tried to run and create a simple UPDATE statement to update a couple of fields with hardcoded data, but this doesn't update. We have also tried creating a stored procedure and then executing this within the SQL Command line in the OLE Destination Editor.
We can see from posts on the net that we can create a procedure in access 2010 and use this. We are also using Native OLE DB\Microsoft Office 12.0 access Database Engine OLE DB Provider. This connection tests successfully.
We can write a SELECT statement within the SQL Command line and this does pull back data. We just seem to have a problem with the UPDATE and or Create Procedure. In turn we are unable to populate the Mappings. the mappings display the destination box but no fields are displayed within here.
We have had a good look around on the internet but we are struggling to find a solution.
Here is a sample of the code in the form of the update statement we are trying to get working.
UPDATE ReferenceFields
INNER JOIN Addresses
ON ReferenceFields.ID = Addresses.ID
SET ReferenceFields.Reference2 =CustomerName,
ReferenceFields.Reference3 = telephone
WHERE Addresses.UPRN = 12345678910
If I Parse the query it is successful but when I select Mappings a warning is displayed....
Error at Data Flow Task [OLE DB Destination [136]]: No column
information was returned by the SQL command

SSIS OLEDB destination with SQL command (Insert if not exists)
After some time I have managed to answer this question myself.
I have added unique parameters to each field I need to update and used the # char to set this.
UPDATE ReferenceFields
INNER JOIN Addresses
ON ReferenceFields.ID = Addresses.ID
SET ReferenceFields.Reference2 = #CustomerName,
ReferenceFields.Reference3 = #telephone
WHERE UPRN = #UPRN
This runs through the code and updates the MS Access database.
I'm running into a problem while linking some tables and views present on a Oracle 11g database to a Access 2007 file.
I'm using the Oracle Client (SQORA32.DLL) version 11.02.00.03.
If the view/table returns a small amount of data, there's no problem. The problem happens when the view or the table returns a "large" amount of data. I've tried to increase the buffer size on the driver (default is 64000) to see if that happens. I've also removed the "Enable query timeout" option - otherwise I would get a "Query cancelled by user" or a "ODBC - Call Failed" error.
In order to link the tables/views, I've used the "native tool" (External Data -> ODBC Database -> Link to data source by creating a linked table).
I was wondering if I could retrieve the data from the tables/views using vba. Sometimes, I (you should read "I" as "the users") may need to update data on some tables (control tables).
Please let me know your thoughts.
EDIT: Our goal with this project was to migrate from SQL Server 2005 to Oracle 11gR2. After analyzing the behaviour of the Access files regarding the SQL Server, I've concluded that the results are showing like a "cursor" - if you scroll down on the result window, it will load more.
I think that this may be the issue because, AFAIK, Oracle (driver, maybe?) pulls everything from the DB and, only then, populates MS Access.
It's a long time after this so here goes the solution. MS access has a flag for the ODBC connection as "Treat Float as Numeric". This have made the trick.
When adding a new data connection in Server Explorer in VS 2010 (with Azure SDK),
I can successfully "Test Connection" but when adding it I get this alert box:
Unable to add data connection.
Failed to retrieve data for this request.
unknown property PrimaryFilePath
(Azure SQL server, i.e. xxxxxxxx.database.windows.net)
Anyone experienced this before?
Thanks!
Edit: It seems to have to do with collation...
...When using SQL_Latin1_General_CP1_CI_AS it works fine but the following does not work:
Finnish_Swedish_CS_AS
Finnish_Swedish_100_CI_AS
Finnish_Swedish_CI_AS
Any suggestions?
I came across the same issue using SSDT for VS 2015. I changed the data provider to ".NET Framework Data Provider for OLE DB" on the Change data Source window and it worked.
The default collation for character data in SQL Azure databases is SQL_Latin1_General_CP1_CI_AS. The server and database level collations are not configurable in SQL Azure. However, you can use a collation of your choice at the column and expression level.
I believe your problem is described here in this blog: Working With Collations In SQL Azure.
This blog article will show you how.
I've got the error "unknown property PrimaryFilePath" when tried to connect to Azure DB from VS 2015, but succeeded when connected from VS 2019.
I have a WCF service that uses Microsoft Enterprise Library Logging to log some messages to the Event Log. That works just fine.
The problem is that i want to log some messages to a table in an Oracle database. I am using the Entity Framework to communicate with that Oracle database.
The next step is a right click on the 'web.config' and choose the option 'Edit Enterprise Configuration'. I get the 'Enterprise Library Configuration' editor. In there i am trying to set the Logging Settings so that it also logs to the database, but when i add a database trace listener it´s asking me to fill in a procedure name. Do i have to add a procedure name to fill the table in Oracle? The msdn tells me to run the script that create an MSSQL database 'Logging' and some tables. But i don't have an MSSQL server, i have an Oracle server. And i don't want to use a seperate logging database, but save the logs to a single table.
Can anybody help me with this?
Kind regards
The Enterprise Library Database Trace Listener uses 2 stored procedures to write to the database: Add Category Procedure and Write To Log Procedure.
There is a SQL Server script to create the tables and stored procedures. This would have to be ported to Oracle.
Unfortunately, it looks like this does not work as easily as you would hope. See the blog post, Enterprise Library Logging to Oracle Database (this is based on EntLib 3, I believe) and the work item Cannot log to oracle Database using logging blocks for a description of some of the issues as well as some downloads to help.
