Inserting And Updating Unicode Strings Via Oracle Provider For OLE DB
Mar 8, 2007
We've installed the Oracle provider for OLE DB on SQL Server 2005, which has the default collation (SQL_Latin1_General_CP1_CI_AS), and we've created a linked server for the Oracle 9.2.0.5 database, which has AL32UTF8 as the database character set. We can successfully insert strings into VARCHAR2 columns on Oracle from SQL Server via EXEC SP_EXECUTESQL('INSERT OPENQUERY(...) VALUES(...)') -- as long as the strings (whether selected from NVARCHAR columns on SQL Server or specified as literals with the N prefix during testing) only contain Windows-1252 characters.
If the SQL statement contains a character above U+00FF, the string on the Oracle side is incorrectly/doubly encoded; there are nearly (but not exactly) 4 bytes per character instead of the 1 or 2 you'd expect from ASCII/Latin-1 characters encoded as UTF-8.
We've tried reconfiguring the linked server: collation compatible = false, use remote collation = true, and collation name = Latin1_General_BIN2. But that had no effect.
What is the correct way to do this?
Thanks!

Since my foxpro OLE driver has been rendered useless by service pack 1 for sql server 2005 I am forced to use the .net data provider for odbc.
I am importing a number of tables.. each time I add the DataReader Source to the dataflow and connected it to the OLE DB Destination I get a load of the good old "cannot convert between unicode and non-unicode string data types" errors...
So I'm having to do derived column transforms, for each and every column that it coughs up on.
Using expressions like (DT_STR,30,1252)receivedby to convert the "recievedby" column to a DT_STR,
Some of these tables have 100 string columns.. so I'm getting a bit sick of the drudgery of adding all these derivations...
Is there any way to tell this provider to stop deciding that the strings in the foxpro tables are unicode?
Thanks
PJ

SELECT * from tableeMass where Name=N'???'
In the above select statement in microsoft SQL server 2005 ,I only want to select all the rows whose name is '???' a Gee'z string(Gee'z is set of Ethiopian characters) it is a unicode string(???=gebru in english,the reason why it is question mark is the characters are gee'z).When we execute the select statement, it brings all the rows instead of the rows whose name is '???'.
why? the data type of column Name is nvarchar(50).would you please
help me in tackling the problem.
please reply me soon,I really need it badly soon for my project of Localized database development.

Here is the situation, please let me know if you have any tips:..TXT files in a share at \fooSPROCS run daily parses of many things, including data on that share. Theother day, we encountered rows in the TXT files which looked like:column1Row1data,column2Row1datacolumn1Row2data,column2Row2data...etc..However, column2 was about 6000 bytes of unicode. We are bulk insertinginto a table specifying nvarchar(4000). When it encounters high unicoderows, it throws a truncation error (16).We really need information contained in the first 200 bytes of the string incolumn2. However, the errors are causing the calling SPROC to abort.Please let me know if you have any suggestions on workarounds for thissituation. Ideally, we would only Bulk Insert a sub-section of column2 ifpossible.Thanks!/Ty

I have an ODBC connection setup for Oralce RDB. This works fine in say MSAccess. Now I would like to add a SQL Server Linked Server to this ODBC driver (it is for RDB not regular Oracle), but I am not able to get this to work. What is the Provider String and Location / Catalog for using this type of ODBC? I setup DSN as 'name', Provider String as 'UID=user;PWD=pass;' and it seems it tries to connect but gives an error. "%SQL-F-SCHNOTDEF, Schema USER is not defined"
Any help is greatly appreciated.

I am building a data warehouse. Some of the data comes from an AS 400 EPR system. I used the OLEDB connector when first pulling the data into SQL Server doing simple import data from table option. That worked great for getting the initial data load into SQL Server and creating the base SQL Server tables although it was excruciatingly slow (that was probably due to the transport from the AS 400).
Now, I need to get new records that are added to the AS400 side of things on a daily basis. For that, I was trying to use the OLEDB AS400 connector. However, I found that the OLEDB connector wouldn't work when I was trying to specify an SQL Statement for what to get; i.e., a simple query like Select * from TWLDAT.STKT where BYSDAT >= '2005-01-27' would simply not work. Found articles here explaining that it is probably a problem on the AS400 side of things and where people recommended using an ADO ODBC data reader source for this type of thing. So, I'm trying to implement that. However, I have a huge problem with it.
The original tables that got created were mapped to use NVARCHAR fields for character data. When the ADO ODBC data reader source accesses the AS400 data, it insists on interpreting the string type fields as being unicode strings and giving it a data type of DT_WSTR when what I need it to have is a plain old DT_STR data type. When the strings are interpreted as unicode strings, they cannot be converted in a way that allows the NVARCHAR fields to be filled with the data. The exact error message I get for all the fields that should wind up being nvarchar fields is as follows:
Column "BYStOK" cannot convert between unicode and non-unicode string data types.
Okay, so I try to change the data types in the ADO ODBC data reader to be plain DT_STR data types and I cannot do so.
Does anyone have any idea why the ADO ODBC data reader source insists on interpreting the string data coming from the AS 400 as unicode string data or why it refuses to allow that to be changed to DT_STR data type?
Thanks in advance for any info. By the way, if there is a better way than the ADO ODBC data source to get at this data when I need to specify an SQL command, I would love to hear about it. Not wild about using ODBC in the OLEDB age.

I have an issue using parameterised reports connecting to Oracle using "ODBC" and "Microsoft OLE DB Provider for Oracle" using parameteried reports. The following error is generated "ORA-01008 not all variables bound (Microsoft OLE DB Provider for Oracle)" and a similiar one for ODBC. It works fine for simple reports. Do these 2 drivers have issues passing parameters for a remote Oracle query?
Thanks.

Hello,
On my dev server I have working ssis packages that use connections Microsoft OLEDB provider for Oracle MSDAORA.1 and Oracle provider for oledb and OracleClient data provider.
I use one or the other according to my needs.
In anticipation and to prepare for the build of a new production server, I have build a test server from scratch and deployed to it the entire dev.
Almost everything works except Microsoft OLEDB provider for Oracle.
ssis packages on the test machine will return an error
Error at Pull Calendar from One [OLE DB Source [1]]: The AcquireConnection method call to the connection manager "one.oledb" failed with error code 0xC0202009.
Error at Pull Calendar from One [DTS.Pipeline]: component "OLE DB Source" (1) failed validation and returned error code 0xC020801C.
[Connection manager "one.oledb"]: An OLE DB error has occurred. Error code: 0x80004005.
An OLE DB record is available. Source: "Microsoft OLE DB Provider for Oracle" Hresult: 0x80004005 Description: "Oracle error occurred, but error message could not be retrieved from Oracle.".
I have used the same installers for OS, SQL and Oracle SQL*Net on both dev and test machines. The install and then the restore/deployment on Test went fine.
Does anyone could point me to the right direction to solve this issue?
Thanks,
Philippe

Hi everybody,
I have designed a DTS package which will migrate a view from Sqlserver 2000 to Oracle.My package is using Microsoft OLEDB provider for Oracle driver for connecting to oracle.Im able to execute this package on the my system ie on the system where sqlclient is installed(Oracle client is also installed on my machine) .But when im doing it on the server im not able to do it.The Connection to Oracle Fails.
I wanted to know in order to connect to Oracle from the server,is it necessary that Oracle has to be installed on the server?.If yes, is it enough if i install oracle client on the server or Oracle Server version has to be installed on Server.
Please suggest me wht should i do know?
Thanks in advance

Hi--
I am running SQL Server 2005 on Win2k3:
Microsoft SQL Server Management Studio 9.00.2047.00
Microsoft Analysis Services Client Tools 2005.090.2047.00
Microsoft Data Access Components (MDAC) 2000.086.1830.00 (srv03_sp1_rtm.050324-1447)
Microsoft MSXML 2.6 3.0 4.0 6.0
Microsoft Internet Explorer 6.0.3790.1830
Microsoft .NET Framework 2.0.50727.42
Operating System 5.2.3790
I have the OraOLEDB.Oracle provider installed to the (C:oraclexe) directory.
I am having problems querying from linked oracle server. When i setup oracle as a linked server and purposely enter an incorrect password the query i run tells me i have an incorrect password. So it at least knows that. when i set the correct password and run a query I get this error:
(i replaced the real server name with "someServer".)
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "OraOLEDB.Oracle" for linked server "SomeServer" reported an error. The provider did not give any information about the error.
Msg 7303, Level 16, State 1, Line 1
Cannot initialize the data source object of OLE DB provider "OraOLEDB.Oracle" for linked server "SomeServer".
This is how I set up my Linked server:
Provider: "Oracle Provider for OLE DB"
Product Name: SomeServer
Data Source: SomeServer
Provider String: "Provider=OraOLEDB.Oracle;Data Source=SomeServer;User Id=MyLogin;Password=MyPassword"
The query I run is:
Select * from [Someserver].[schema or database]..[tbl_name]
Any help??? What am i missing?

I am very new to SQL Server 2005. I have created a package to load data from a flat delimited file to a database table. The initial load has worked. However, in the future, I will have flat files used to update the table. Some of the records will need to be inserted and some will need to update existing rows. I am trying to do this from SSIS. However, I am very lost as to how to do this.
Any suggestions?

Hi,
Could someone please tell me how to update data in a column that contains unicode data in SQL 2000?
I know how to write update scripts on my own, but when it comes to Unicode character updates I canÂ?ft manage. In the script that I have pasted below I can update the customerÂ?fs details, but this only works if I update with Romaji characters (non-unicode).
The data that I need to update is in Japanese Kanji, but when I use the 'Update' script below, the data is updated as all question marks (???????????).
Is it very much harder to get the script to where it will handle Unicode characters and insert the correct data?
UPDATE CUSTOMER_LANGUAGE_DETAILS
SET FIRST_NAME = '‰h�s'
WHERE CUSTOMER_ID = 1592

Hi.
We have a sql server db that we need to store Unicode text in. The fields are of the type nvarchar, ntext and nchar. Our solution uses both Oracle and SqlServer as a backing database. In Oracle there is a connection string switch "Unicode=True" that fixes the problem. Is there something similar in SqlServer? Since the db layer is generic we'ed like to avoid using a N' prefix on text strings in query statements.

Hi Everyone,
I've been searching for a solution for this for a week-ish, so I thought I would post my quesiton directly. Here is my scenario..
Source: MS SQL Server
Destination: Oracle 10g
The destination table has a partition set on a column called "DATE_HIGH". How do I populate this date high column in my package? Currently I just have a source object, and a destination object, but I'm unclear how to populate this field in the destination. I've read one blog that states "use OLE DB Command" - but that isn't enough information for me to implement - Can someone be more specific in these steps? Here is an example of what my newb-ness needs to understand
OLE DB Source (Select * from Table) ---> OLE DB Command (What query goes here?) --> OLE DB Destination.
Second part of my question: There is a second column called "ROW_NUM" and there is an Oracle Sequence provided to me... What objects do I need (Source, Destination, OLE DB Command etc...) and how do I call this sequence to populate on the fly as I'm loading data from my source?
If these are simple questions - my appologies, I am new to the product.
Best Regards,
Steve Collins

Since the .net oracle providers are the only ones that work in x64 it is extremely annoying that it insists on mapping ALL varchar columns in oracle to wstring. Is there a way to fix this? The oledb providers don't have this problem but I don't like being forced to use the 32 bit runtime as a workaround.

I have to write a query to update the table to remove dots .... from the string value.
so i could write.
UPDATE tbaddress
SET Title='New address'
WHERE Title='New address....'
but, there could be more than this specific record in the table, so i have to find each single record to do this. Is there a way to update the table so I can just remove the .... but rest of the text remain.
thanks

Hi: Got a newbie question that's been giving me fits! Basically I'm replicating what's going on here on this board...creating a "posting" interface that takes the "message" and inserts it into a table using an ADODB connection (using INSERT INTO table name,tablecells and VALUES)
However, if someone types in a single or double quote in the body of the message, I get an error similar to this:
Microsoft OLE DB Provider for ODBC Drivers error '80040e14'
[Microsoft][ODBC SQL Server Driver][SQL Server]Line 1: Incorrect syntax near 's'.
/test.asp, line 29
I think I understand why it's happening (SQL is interpreting the quote mark as a string-end), but what am I supposed to do to get around it?

Hi all,
If have faced the following problem when connecting to Oracle server from MS SQL Server 7.0 using OLE DB Provider for Oracle.
The problem is that I am trying to insert a record in a table in Oralce database, when I connect using OLE DB, and execute the INSERT, I have found that before the INSERT takes place, a TABLE SCAN is performed on the target table for the insert statement.
This realy affects the performance I am looking for.
I guiss there is a way to provide the connection with some parameters to overcome this problem of TABLE SCAN.
Thanks for your help in advance.
Regards.

english:
Hello,
I have got a problem with the a linked server in SQL server 2005 (64 bit) to Oracle 8.0.5. (32 bit).
Further details:
The old existing SQL server 2000 (32 bit) has a linked server to Oracle 8.0.5. The works with the OLE DB provider from Microsoft. The new SQL server 2005 (64 bit) should also have a linked server to this Oralce database. I have installed the Oracle 8.0 clients on the new server. The connection to oracle works with the client tools from Oracle.
But the SQL server 2005 couldn't connect to the oracle database.
The error message from the SQL server sounds (translated form a german error message):
A instance of the OLE DB provider "OraOLEDB.Oracle" for the linked server "xxxxxx" can't create.
Is the Oracle client software / OLE DB provider the problem?
Exist an other OLE DB provider for Oracle, may be from Microsoft, which works?
Thanks for your help

Hallo Zusammen,
Ãch habe ein Problem bei der Migration von SQL Server 2005 auf ein x64 Windows System.
Problem ist folgendes:
Auf dem alten Server Windows x32 lief SQL Server 2000 mit einem Verbindungsserver zum Oracle Server 8.05. Das funktionierte mit dem OLE DB treiber von Microsoft hervoragend. Nun haben wir aber eine neue Windows x64 Maschine und ich möchte die Verbindung zum Oracle Server wieder nutzen. Hatte die Oracle Client Software installiert und bekomme eine Fehlermeldung:
Eine Instanz des OLE DB Anbieters "ORAOLEDB.ORACLE" für den Verbindungsserver "xxxxx" kann nicht erstellt werden.
Ist das ein Problem mit der Oracle Client Software bzw. dem zugrunde liegenden OLE DB Treiber?
Gibt es einen anderen OLE DB Treiber für Oracle, z.B. von Microsoft, der funktionieren könnte?
Bin schon länger damit beschäftigt, das zum Laufen zu bekommen. Die Oracle Version ist nicht die neueste, ich weiß.
Was kann ich tun, damit das endlich läuft.
Für Hilfen wäre ich sehr dankbar.

Hi,
I issued the following set of statements against an Oracle 8.0.6 table linked to Microsoft SQL Server 7.0 (SP2):
BEGIN TRANSACTION
DELETE FROM ORACLE_DATABASE..SCHEMA1.TABLE1 WHERE COLUMN2=123.45
ROLLBACK TRANSACTION
and received the following message:
Server: Msg 7391, Level 16, State 1, Line 1
The operation could not be performed because the OLE DB provider 'MSDAORA' does not support distributed transactions.
I searched BOL and found this sentence:
To perform distributed transactions between SQL Server and Oracle, you must use Oracle version 8.0.4.1 or later.
What am I missing? Is there a higher version of Microsoft OLE DB Provider for Oracle that supports distributed transactions (we are using the one that comes with Microsoft SQL Server 7.0 installation)?

Hi,I created a linked server for MS SQL Server 2005 Express to an Oracledatabase using the OLE DB Provider for ODBC. My ODBC Source uses theMicrosoft ODBC for Oracle driver.I'm using the OLE DB Provider for ODBC instead of the Oracle OLE DBproviders because those don't handle Oracle's Numeric Data Type well.When I set this up yesterday it worked fine. However I log in today andattempt to run sp_tables_exec against my linked server and get thefollowingOLE DB provider "MSDASQL" for linked server "WHATEVER" returned message"[Microsoft][ODBC Driver Manager] Driver's SQLSetConnectAttr failed".OLE DB provider "MSDASQL" for linked server "WHATEVER" returned message"[Microsoft][ODBC Driver Manager] Driver's SQLSetConnectAttr failed".OLE DB provider "MSDASQL" for linked server "WHATEVER" returned message"[Microsoft][ODBC driver for Oracle][Oracle]".Msg 7303, Level 16, State 1, Procedure sp_tables_ex, Line 41Cannot initialize the data source object of OLE DB provider "MSDASQL"for linked server "WHATEVER".I can tnsping the server, and I have no trouble connecting with theOracle OLE DB providerI try to set up ODBC logging but the log file is blank -- same withattempting to set up logging for Oracle's network client.

I have been using the Microsoft Oracle Provider (MSDAORA) up until I needed to work with CLOB data types in Oracle. As much as I hate to switch providers at this phase in the project, I can't use MSDAORA due to the CLOB limitation.
So, what other providers are available?
I know that there is a native Oracle provider (OraOLEDB.Oracle.1) that is supported in SSIS. Does anyone have any comments on this?
Are there other options for Oracle?
Any comments, feedback, etc appreciated.
Thanks,
Rick

Hi. I am trying to establish a connection from ssis to oracle using oracle provider for ole db on a 64 bit windows box using the 64 bit oracle provider.
Steps done
1) installed the oracle 10g 64 client
2) installed the odac 64 bit
I am able to connect to oracle using sqlplus fine. i can also see oraOLEDB.oracle listed as a provider in the linked server providers in sql server management studio.
when i try to set up a new data connection in ssis I don't see the oracle ole db provider listed. Since then I have registered the OraOLEDB10.dll but I still don't see the oracle provider listed.
Can some one through me a line ? Thanks.
