Hi
I definite a source OLEDB MS Access and my fields of the type €œText€? are seen in type of field DT_WSTR (Unicode) instead of DT_STR.
I do not include/understand why? and like then, I must integrate them in fields varchar and not nVarchar, I do not find the solution?
thank for your solution
I have a WinForms C#.net application in which I export data to MDB files. To create the initial database I use this code:
public static bool CreateDatabase(string fullFilename) { bool succeeded = false; try { string newDB = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fullFilename; Type objClassType = Type.GetTypeFromProgID("ADOX.Catalog"); if (objClassType != null) { object obj = Activator.CreateInstance(objClassType); // Create MDB file obj.GetType().InvokeMember("Create", System.Reflection.BindingFlags.InvokeMethod, null, obj, new object[]{"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + newDB + ";" }); succeeded = true; // Clean up System.Runtime.InteropServices.Marshal.ReleaseComObject(obj); obj = null; } } catch (Exception ex) { Tools.ShowMessage("Could not create database file: " + fullFilename + "" + ex.Message, "Database Creation Error"); } return succeeded; }
This works perfectly fine on my system. But I've learned from one client that such MDB files cannot be opened using MS Access '97. Why they're still using this old version is a great question but the customer is always right, right?!
Anyhow, I thought that I could just alter the number "4.0" to "3.5" or "3.0" but it doesn't work on my machine. I got to wondering though if it might work on a client's machine if they had that version of OLEDB data access components installed.
So I'm wondering how I can programmatically test for which version(s) of OLEDB are available to use?

Hello, Code below returns the following error:
Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done

Const adLockBatchOptimistic = 4
Const adUseClient = 3
strDataBase = "somedb.mdb"

cnTraining.Open cnnstr
set rsSearch = Server.CreateObject("ADODB.Recordset")
rsSearch.CursorLocation = adUseClient

sSql = "some sql stmt" 'this works fine on its own
rsSearch.Open sSql, cnTraining
set rsSearch.ActiveConnection = nothing
cnTraining.Close
set cnTraining = nothing
%>
My goal is to get a disconnected recordset. The problem here occurs when i try to use the adUseClient value (3) for the CursorLocation. If I don't use a 3 in the CursorLocation it works fine. Hoewever i'm almost certain i have to use the 3 in order to disconnect the recordset. Any ideas? Is my connection string not set up properly to get a disconnected recordset?
Hi all,
I am currently working on a stored procedure in SQL 2000 where I use OPENROWSET function to read data from an Excel file into a temporary table.

"Ad hoc access to OLE DB provider 'Microsoft.Jet.OLEDB.40' has been denied.
You must access this provider through a linked server."
I am using VB 6.0 as front end. Is there anyway i can overcome this error?
Please help.

I have a stored proc that runs and produces an Excel 2007 file. I can run it fine within SQL Server Management Studio.
Basically, this is a partial code in the stored proc:
-- export sql server table data to excel 2007
insert into OPENROWSET('microsoft.ace.oledb.12.0',
'Excel 12.0;Database=D: emp est2007.xlsx;',
'SELECT * FROM LicensesrRegion') select * from Licenses
BUT when I have an execute SQL task to run that stored proc in an SSIS package, I received the following error:
Ad hoc access to OLE DB provider 'microsoft.ace.oledb.12.0' has been denied. You must access this provider through a linked server.
Please advise.
PS: I have to run that stored proc in an SSIS package because the SSIS package does some prereq stuff ( create folder, copy template to new Excel output file) then finally calls the aforementioned stored proc.
Thank you in advance.
Thanks!
We are experiencing failures when accessing a datatype="Attachments" field in a query in an MS Access 2007 database using ACE ODBC or OLEDB drivers.
We are using an MS Access 2007 database
ACE ODBC/OLEDB drivers installed (i.e. Office 2007, which installs these drivers)
DB contains a table with a field of type "Attachments" (which is new in MS Access 2007)
DB contains a query that selects the fields of the above table
Using ACE ODBC or ACE OLEDB drivers to display the table works fine. The "Attachments" field is displayed as the file name of the attachment(s).
However, using either ACE ODBC or ACE OLEDB to display the query (i.e. NOT the table) results in either incorrect results or unexpected failures of the ODBC/OLEDB drivers.
Error using ODBC (using "ODBC Test"):
=============================
select * from Query1 does not give an error, but displays a "1" for the Attachment field.
select Attachments from Query1 gives the following error:
stmt: szSqlState = "HY000", *pfNativeError = -3087, *pcbErrorMsg = 97,
*ColumnNumber = -2, *RowNumber = -2
MessageText = "[Microsoft][ODBC Microsoft Access Driver] Reserved error (|);
there is no message for this error."

If it would help to analyze the problem, I have a folder containing all pertinent files (bare-bone database, tools, instructions) to reproduce this. I could attach it as a ZIP file, if requested.

I have a linked server defined on a SQL Server 2005 SP2 standard edition server using the IBMDASQL OLEDB driver. The linked server has been defined and working for months when used from a SQL Server authenticated session. I started converting our developers to Windows Authentication and access to the linked server is denied when used from a Windows Authenticated session. Here are the error messages:
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "IBMDASQL" for linked server "DB2ARUBA" reported an error. Access denied.
Msg 7350, Level 16, State 2, Line 1
Cannot get the column information from OLE DB provider "IBMDASQL" for linked server "DB2ARUBA".
The linked server security is defined to login to the IBM iSeries using a fixed user and password regardless of the login using the linked server.
In order to analyze the problem, I created one sysadmin SQL Server authenticated login and one sysadmin Windows Authenticated login. The Windows Authenticated login refers to a domain login having administrator priviledges on the local SQL Server box.
So, when I connect to SQL Server using the SQL Authenticated login, a query against the linked server works. When I connect to SQL Server using the Windows Authenticated login, the exact same query against the linked server fails with the messages above.
Does anyone know why?
Thanks for any one can give me a help.
I am try to transfer some tables data from one database server into another database server. I create a package in SSIS, and I use a variable to pass each table name. In Data flow, I use a OLEDB Source, but I cannot set the Data access mode to Table name or view name variable. Ever time, I will get this following error info "===================================
Error at Data Flow Task [OLE DB Source [31]]: A destination table name has not been provided.

Some one can tell me what is the reason, or give me some examples.

Is anyone using OLEDB instead of ODBC? If so why did you choose to use OLEDB vs ODBC? Our application is written in VB and we have a developer that believes switching to OLEDB from ODBC would be beneficial to us. Please give any information that you have! Thanks.

View 1 Replies View RelatedI am working on a large ASP application(s) which uses SQL Server 2K on the back end, ADO 2.7 for Data Access. The current connection strings are setup to use older ODBC drivers. I wanted to change them to OLEDB for performance gains and better support in the future.
The problem encountered is that once the driver is changed the pages become riddled with errors. There are many piece of ADO code that are supported using the new driver. Many are cursor issues or code dealing with identity columns.
Has anyone else gone through this process?
Is there a comprehensive listing of those methods that are not compliant between these two drivers?
Any input would be appreciated....Thanks
Dear gurus,
My problem: I have developed an application based on sqloledb to access a SQLserver application.
One of the operations is to update certain column of a certain table. This works fine. But with a specific catalog (database) of a specific customer the update hangs for ever on the execution of that sql sentence. Size of the mdb file is around 1 Gb.
The funny thing is that if I execute the same sql sentence (same record and same catalog) from the Query Analyzer ( that I belive it uses odbc ) the operation is done.
The update sql sentence does an update on a non-indexed column with the criteria ( where ...) using a index column (non-clustered)
I have tried the sqlmaint to rebuild indexes and check integrity and no special error report is given.
Also another funny behaviour is that if I stop and I restart sqlserver, the update of that specific record fails, but it continues of the following records to be updated.
This is not executed inside a transaction. Candidate records to be updated are stored in memory (maximum 1000), and one by one are updated.
Does anyone know an specific tool to integrity or to monitor what is going on?
I have tried the profiler , what can I monitor to detect this lock?
Best regards,
Jose

I am pursuing a course on Data Warehousing & Data Mining as part of my Post-Graduation degree. I got an introduction to Microsoft's OLEDB for DM as part of the course, which got me interested for experiencing it hands-on.
I developed a traditional Database application for my college's library using the .NET 2.0 framework, which is running fine.
Now, I want to see the power of Data Mining in general & OLEDB for DM in particular, to help me mine information & patterns from the mostly transactional data generated by the library daily, like the rush hours, the average issue duration for a book, books that are issued more frequently, books that are issued to students from multiple streams etc. etc.
Now, I have heard MSOLAP provider, ADOMD data provider, SQL Server Analytical Services, OLEDB for DM libraries etc. are required for Data Mining.
Now, what exactly is each of these tools? Are they independent servers for DW & DM like SQL Server for DBs, or they are libraries for extending SQL Server itself?
Moreover, are separate libraries required for OLAP & Mining?
I have SQL Server Express Edition. I believe that they are extensions for SQL Server. So, will they work with Express Edition? If not, are their Express Editions available (like OLEDB for DM Express!!!!) that are compatible with SQL Server Express.
Thanx in advance if you take time to answer so many questions...
I want to use SQL 2005 to import data from Visual Foxpro 6.0 free table / database into SQL 2005. Whethter I should install the latest Microsoft OLE DB Provider for Visual FoxPro 9.0 SP1 or previous mdac ???
Please advice and many thanks.
I generated an ATL OLEDB Consumer with the VS 2005 wizard. The table is very simple and is located on my local SQL Server. It has two varchar columns and no keys or constraints. I can modify, insert and delete rows with no problem.
Now I want to use bookmarks. I added the following to the accessor class:
1. CBookmark<4> m_bookmark; // member variable
2. pPropSet->AddProperty(DBPROP_IRowsetLocate, true); // rowset property
3. BOOKMARK_ENTRY(m_bookmark) // column map entry
Now I can delete but I can no longer modify or insert. The error is DB_E_ERRORSOCCURED and the status of the two columns after a setdata or insert is DBSTATUS_E_UNAVAILABLE. This is the only error information available.
When I comment out the bookmark entry from the column map, I can modify, insert and delete again. The problem appears to be in how IRowsetChange handles bookmarks. I tried adding bookmarks to other tables using the above 3 steps and they also refuse to modify or insert with bookmarks enabled.
The bookmarks appear to be correct, as I can do a successful MoveToBookmark for any row in the table.
My environment: Windows XP SP2, VC++ 2005, SQL Server 2005 Express, WTL 8.0
Any ideas?

I am porting a VB.NET application using Access as its backend to use SQL Express as its new backend.
The application uses .NET 2.0 OleDbProvider to connect to the database.
The porting of the database itself to Sql Express is nearly complete, now I need to modify the application.
So, does it really make sense to modify it to use Native Sql Client instead of OleDb in terms of effort & benefits???
Moreover, if I continue using OleDb, would I need to make such small changes to embedded Sql statements like using single quotes around strings or dates instead of double quotes or pound symbols that are currently being used for String or date data respectively???
