I was trying to pull data from Oracle to MSSqlserver database using Linked server.
select * from [LINK_NAME]..SCHEMA.TABLE;
But it was failing with the below error:
The OLE DB provider "OraOLEDB.Oracle" for linked server "LINK_NAME"
supplied inconsistent metadata for a column. The column "COLUMN_NAME"
(compile-time ordinal 6) of object ""SCHEMA"."TABLE"" was reported to
have a "LENGTH" of 100 at compile time and 200 at run time.
I also need to pass argument at run time in where condition. I found OPENQUERY as a solution but it does not support arguments at runtime.
Try using the OPENQUERY Syntax to see whether that helps..
SELECT * FROM OPENQUERY(LINK_NAME, 'SELECT * FROM db.Schema.Table')
More about OPENQUERY ...
I found solution:
The error was coming due to database column type mismatch.
ORACLE was using NVARCHAR for datatype but in case of SQLSERVER it was VARCHAR.
As NVARCHAR is double the size of VARCHAR that is why it was showing size mismatch error.
Changing the data type to same worked for me.
I have found a solution posted by this blogger. Try it out!
This tool from Sysinternals/Mark Russinovich is the best, and my only regret that day was not launching it earlier instead of scouring Google and going insane. I’ve limited Procmon to just sqlservr.exe, as it’s the SQL Service itself that loads/handles the providers and not the ssms.exe. Also of note is that the sqlservr.exe is a 64bit process while the management studio is still just 32bit. As the server service is loading the provider, and the service process is 64bit, the provider must also be available in 64 bit format.
The ODAC112021Xcopy_x64.zip was installed to C:\Oracle. What Procmon showed me however is that sqlservr is attempting to find the oci.dll in any folder but his! (It iterates through the %Path% sysvariable). When it finally gives up on find the dll, the SQL Service is in a unstable shape and the only way to stop the service was to kill it via taskmgr/procexp. Clearly I can see that the “xcopy” deployment – while not giving me any error messages – it also did not set the PATH variable! And this is what this post is really about… adding C:\Oracle and C:\Oracle\Bin to the Path variable or maybe it’s about employing investigative tools earlier in the process instead of relying on your search engine skills.
sqlservr.exe can now find the relevant DLL’s. The OCI.DLL in the root and the OraOLEDB11.DLL in the Bin subfolder. At this point I could query the database! If you did my steps as above and you still get the same error, I strongly suggest using Procmon.exe as I have instead of jumping to the next search result.

I'm trying to use SSIS to load some data from Oracle database to MSSQL database.
I created the project and used the ADO.Net source and was able to create a connection to Oracle and run queries and view results.
However when I actually run the package I get the following error:
Error: 0xC0208449 at Data Flow Task, ADO NET Source 2: ADO NET Source has failed to acquire the connection {EECB236A-59EA-475E-AE82-52871D15952D} with the following error message: "Could not create a managed connection manager.".
It seems similar to the issue here
And I did find that I have two oracle clients version installed "11.1" and "12.2".
One is used by PL/SQL and the other by other entity framework project.
If this is the issue I just wanted a way to tell the SSIS to pick-up the correct one.
I tried adding Entry in machine.config for "oracle.manageddataaccess.client" section with the desired version.
I also tried using other types of data sources but couldn't even create a successful connection
I tried changing the Run64bitRuntime property in the project to False
Note: I don't have SSIS installed on my machine.
Eventually, I just had to remove the entries related to 11.1 in path variable then restarted my machine.
Also I switched to "dotConnectForOracle" for connection and now it seems to be working fine.
I'm expecting issues related to other applications that might still be using the 11.1 version, but that will be a problem for another day.
Always make sure to write the user (oracle schema) in uppercase and some special characters [in my case it was $] in the password needs escape character even if you're using the wizard not the cmd
I still don't understand the whole issue but I hope this helps someone some day.
I've an SSIS package which works perfectly on various server but doesn't on 2 newly added server.
It uses OLEDB (64bit, I've certified that) to get data from an ORACLE DB from a table with 3 VARCHAR2 columns and upsert the rows to a SQL 2012 table with 3 nvarchar columns, with the same size.
The package was working flawlessly in all the servers we deployed it. We recently added 2 new servers, with hopefully (I personally checked the possible major culprit: ODAC, dtexec version, tns names ) the same software with the same versions but the package is not working anymore. It gives us the famous error:
Description: Column "C_CODE" cannot convert between unicode and non-unicode s
tring data types.
End Error
Error: 2016-08-26 08:33:26.20
Code: 0xC02020F6

Description: Column "S_DESC" cannot convert between unicode and non-unicode s

End Error

Description: The external columns for OLE DB Source are out of synchronizatio
n with the data source columns. The external column "C_CODE" needs to be updated
.
The external column "S_DESC" needs to be updated.
End Warning
The first warning I got was the "Cannot read the code page from Oracle server" so I tried to put the "use the default one every time" in combination with ANSI or UTF-8 code pages ( used this website to get the codepages: https://msdn.microsoft.com/en-us/library/windows/desktop/dd317756%28v=vs.85%29.aspx ).
The only way I made it work was to manually modify the OLE DB Source block into the package by changing the external columns to ansi strings, making it not compilable in the dev environment, then put a data transform that would change the exernal columns to utf-8 string again.
This way it doesn't work in the other servers but does flawlessly in the "faulty" servers.
I was thinking that the fact the package cannot read the code page from Oracle server is the culprit but I couldn't figure out how to fix it.
The problem is not like the million of questions about this issue you can find anywhere. The error being given is from the OLE DB Source block. I know about the data conversion.
Thanks in advance
The issue was the NLS_LANG registry key's value, it was set to an incorrect value.
I solved by deleting the said key, all worked fine.
Just come across this post (and many others about this issue) and believe I have found the underlying cause. On my servers at least, the 64bit version of the Windows Oracle drivers has a bug in the install process. I have checked the 32bit version and this bug is not there which explains the behaviour.
It appears that the 64bit version creates the NLS_LANG registry key in the wrong location. By default the 64bit driver create it here - "HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE"
I manually created it here - "HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_OraClient12Home1" which cured my issue. For reference my NLS_LANG key is set to "ENGLISH_UNITED KINGDOM.WE8MSWIN1252". I just created it as a copy of the string in the branch above.
I hope this helps others.
We use 32 bit SSIS with Oracle instant client, I need to add entry in this registration location
"Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\ORACLE\KEY_OraClient12Home1_32bit"
The “NLS_LANG” value is “AMERICAN_AMERICA.WE8MSWIN1252”. This solved my problem.
I tried to run this procedure "sp_oledb_getcolumnprivileges" for oledb connection which i got from here, i have ran "sp_configure 'enable java', 1" and restarted Sybase and my result is
- Default -0, Memory Used -0, Config Value-1, Run Value -0,
Unit-switch, Type -static.
but when i try to run the procedure the error is still the same
I'm afraid you're barking up the wrong tree here.
The stored proc you picked up from that web site was not for ASE. As the comments in its header show, it comes from MS SQL Server. It seems quite dumb from whomever runs that web site to execute this on ASE, since it is pretty obvious this won't work -- these are two different brands of databases.
Also, this has nothing to do with Java. The reason you may see error messages in ASE mentioning Java is that this MSSQL Server code seems to call functions that apparently exist in MSSQL but not in ASE. What follows is a standard error message mentioning Java (since you could have written function in Java which you're calling from SQL -- but 99.9% of the time that error message just means you're calling an unknown function).
Bottom line: don't expect the procedure from that web site ever to work in ASE.
I am using SSIS with VS2010 (shell) and databases going from SQL Server 2005 (32 bit)to SQL Server 2012 (64 bit). I am developing directly on the destination server (not optimal, but it works).
When I try to use the Transfer database task, it gives me an error message as follows:
"Error: The Execute method on the task returned error code 0x80131500 (An error occurred while transferring data. See the inner exception for details.). The Execute method must succeed, and indicate the result using an "out" parameter."
Here is the problem... how do I view an "inner exception"?? it is a GUI interface with no way to step through the code! I even tried setting up logging - it just logs the same useless error message.
Microsoft has no information for this error code in their reference docs (that I could find).
After googleing the error code, I saw others have this error code along with messages having to do with users, roles, and creating them.
I double checked that I have sysadmin rights on both servers, and
logins on both.
I tried the same Transfer Database task from each
server to itself (with changeing database name) and that worked
fine for both by themselves.
I tried both DatabaseOnline and DatabaseOffline options. (same error both ways)
I tried doing a "Transfer Logins" task before doing the transfer database task, that task worked, but not the Transfer databases task. Then it started throwing errors saying that the databases don't exist - which implies that I need to transfer logins AFTER I transfer databases.
Here are my settings:
What am I doing wrong? OR how can I get the "inner exception" message?
Also, follow my post to Microsoft's forums here:

This answer makes me sick to my stomach... I hope I save someone else this hassle. The problem was this:
First and foremost: the error message was not descriptive enough. The error should be handed to the interface.
Under "edit" on a "Transfer Database" task, the destination file paths are "auto-populated" with the file paths of the source database. They look right at first (and second, and third...) cursory glance. Upon further inspection the file paths were wrong. This makes sense if you are going from version to version - the folders are named with subtle differences according to version (MSSQL.1 vs. MSSQL11.<instanceName>).
In summary, the error was caused by the folder not existing because the path was set wrong. I imagine other low-level exceptions like this are also eaten by the interface with the same cryptic error message.
This is old but I bumped in the same cryptic message with SSMS 17.2. I tried and checked all the suggestions above to no avail.
In my case the issue was related to the TargetServerVersion property of the SSIS project in Visual studio 2017. By default this was set to SQL Server 2017, while my local server was SQL Server 2014 - once changed to the same version everything went smooth.
We ran into this where someone told us a valid date would always exist in the column in a MySQL database and we found out later that there were dates like '0000-00-00 00:00:00' and '0001-01-01 00:00:00'.
We handled it in the query that pulls in the data using a case statement to convert the bad date into a date SSIS can use :
CASE WHEN Product.PurchaseDate < '1900-01-01 00:00:00' THEN '1900-01-01 00:00:00' ELSE Product.PurchaseDate END AS PurchaseDate
Of course, you can set it to null also, your choice.
I have also had this same issue and it turned out to be an access issues. Try giving these access to the folder where the mdf and ldf files will be landing: NT Service\MSSQLSERVER, Owner Creator, System
"which implies that I need to transfer logins AFTER I transfer
databases."
not really, logins are on a server (instance) level so you can transfer logins and then the database. You would need to worry about users later, of course
a point here, I dont think SSIS would be prepared to transfer 2005 -> 2012. I mean, It wouldn't make sense to "skip" a version. You said you are using VS 2012, so it would be SSIS 2012. It think it can read only 2008 databases. The fact that you tested on the same server and it worked also makes this point stronger.
I'm fairly new to SQL Server. I have done basic admin, backups etc. I have also spent 2 years doing MySQL for a software company offering software support for their MySQL bespoke program. I'm mainly a tech guy (desktop, Networking) but getting my head round this DB stuff!
I have started with a company that run SQL Server 2005 and need some stuff doing, and I am struggling with the syntax more than anything. The company have 4 SQL Servers running the same db's (program wise) for 4 differing locations.
What I am trying to do is copy the updated cost price list from table 1 to the other tables with * criteria. Basically copy table.parts from server1.parts to server2.parts * currencyconvertion field * markup (%)
That bit seems to be quite easy except I cannot get the db's to link. I enter the server name which contains - and the syntax says wrong eg uk-server1 'can't find 'uk'? Also I am unsure in the 4 part address is correct servername, dbname, schema, table?
Right ok. Previously when tried I was unable to link the two servers. I have now resolved this and the server is now linked. I have been told that maybe there is a need for [] to quote'' server name. I have tried this with no success. The problem seems to be the name of the server having a - uk-efacs. as soon as I type this and remember it is now linked the herror is can't find server efacs an uk is wrong?? It's not ready the full server name? WHY?
Figured this out by trial and error just needs [] by server name ie [uk-efacs].db.table.field. This now is ok just need to work on my syntax as the query shows errors.
Try creating a Linked Server record on the server you're running this from. In Object Explorer (in SSMS) expand Server Objects, right click Linked Servers and select new. Select SQL Server and type the name of your remote server and then try your query again. Bit puzzled as the snippet you provided
update partmaster
set partmaster.fsunit = uk-efacs.efacsdb.partmaster.fsunit * uk-efacs.efacsdb.currency.currate * 1.32
Seems to parse just fine.
