 - Problem using OLEDB connector Hi, I am trying to insert data into an Excel sheet using Microsoft Jet OLE DB 4.0 driver. One of the fields is exceeding 255 characters. I get the error: "The field is too small to accept the amount of data you attempted to add. Try inserting or pasting less data" This is surely not a problem with Excel since I put in the data manually. Please let me know if we have a solution/workaround for this. Thanks, Pranav.

 - Correct SP:s not executing I often use ADO.NET and SP:s, but now I'm stuck after spending all yesterday on two issues 1) ARITHABORT A form calls SP to insert a record, but executing it only results in the following message :"Insert failed becase the following SET options have incorrect settings 'ARITHABORT'". I've checked the SQL Server documentation and can't see how it at all applies in this case. Tracing the command in SQL Profiler this is what it looks like exec insertReportPeriodExchangeRates @FromCurrencyID = N'GBP', @ToCurrencyID = N'USD', @ExchangeRate = 1.600000, @ReportPeriodID = N'2004Q3', @ReportPeriodExchangeRateID = @P1 output, @TimeStamp = @P2 output If I execute that command from SQL Analyzer it works just fine. No error message 2) .SP does not execute at all Another form calls a SP to delete a record, but the SP is never executed! How is that possible? Tracing the command in SQL Profiler this is what it looks like exec deleteReportPeriods @Original_ReportPeriodID = N'2003Q5', @Timestamp = 0x00000000000083C1 If I execute that command from SQL Analyzer it works just fine. All in all about 200 SP:s are called in the application, and these are the only one that failing. Again, if I run them from SQL Analyzer they execute correctly, so there is something odd happing in ADO:NET. All the commands are executed from inherited forms. Any ideas where to look?

 - Concurrency violation: the DeleteCommand affected 0 records ----------------------------------------------------------------- The PK in the oledbdeletecommand.parameters collection *appears* to have the appropriate Primary Key to look for to delete, so I'm not sure why it's not able to find the record to delete... After reloading the master form, the datarow deletes and the dataadapter.update(me.ds) goes just fine. ----------------------------------------------------------------- I have two forms in a master/detail relationship, with the master form's dataset shared with the detail form.

 - Why aren't there any interfaces?? I'm working with DataSets in my code and cannot find a suitable Interface to reference. As a work-around, I've written an Interface (IDataSet) that defines all of the public method signatures of a DataSet class. A custom class (DataSetExt) implements that Interface and delegates public method calls to *base*. I know that in taking this approach I've left myself open to a slew of potential problems especially if the signatures of the DataSet class change. However, the System.Data.DataSet class has no primary interface....???? Any thoughts on this? thx Tag: Using OracleType.Clob Parameter ? Tag: 76399

 - Updating and Access table with more than 127 columns Due to an existing limitation of Access, you cannot issue an UPDATE query with more than 127 fields (Access has a limit of 255 fields and during an update query, both the column your are updating and the value your are inserting are treated as fields, which therefore limits you to having 127 columns in your query). ADO didn't have a problem with this if you used a connected recordset (I'm assuming because it uses cursors or something). Since updates are submitted via UPDATE queries in ADO.NET this becomes an issue. Making the table have less than 127 columns is not an option as there are existing implmentations of the database (using old clients that used VB and ADO that worked...). Only updating the 'changed' fields does not solve the problem as the problem still exists when you change more thant 127 fields... There are issues with splitting the UPDATE into 127 field chucks if some of the fields more then one chunk are marked as 'required'. My question is, is there any way to deal with this issue in ADO.NET? I don't want to have to resort to using interop and old ADO recordsets but it appears to me like this is the only way to deal with this issue in a generic way.

 - HELP serious performance degradation compared to QA I have a stored procedure that takes 4 seconds to execute (returning 3840 rows) from Query Analyser, yet when I fill it using the following (assume the variable SQL is the stored procedure) Dim cmd As SqlCommand Dim ds As New DataSet Dim sa As SqlDataAdapter cmd = New SqlCommand(SQL, cn) sa = New SqlDataAdapter(cmd) sa.Fill(ds) it times out or takes much, much longer than 4 seconds - on the order of a minute. This delay has a lot of corresponding server processor activity but absolutely none for the client. I've read some previous posts about timeout issues, but none of them explain this performnace degradation. All I want is the data, and no extra overhead. Is there any way in .Net I can get the *same* performance that I get from QA? The same problem happens in VB6 using recordsets - the 4 second query takes 62 seconds. I already looked at the DataSetSurrogate and it performance is worse. http://support.microsoft.com/?id=829740 DataReader shows the same behavior/problem, only it times out at 30 seconds and reports "system error".

 - ASP.NET Automatic vs. Manual ado.net objects Hello, I'm hoping someone here can help me out with this. I'm programming with asp.net within the VS.NET IDE. I've found two different ways to handle data access, I can program my own ado.net components, or drag and drop from the toolbox connections, adapters, datasets, etc. to the design view of the web form. I like the drag and drop features, but would like to know more about it, I kind of just stumbled on it, and never really found a good document explaining it. Does anyone out there have experience with this, and could offer any insight. Any showstoppers someone has run into from using the automatic stuff versus do-it-yourself. In the long term what will be the best option? Thanks for any help! --Michael Tag: Using OracleType.Clob Parameter ? Tag: 76335

 - Row Cell Hello, Coming from VB, accessing cells is a little different in C#. If I have a datatable, I see the ItemArray propery, which gives you an array of the items in a row (right?), but it does not allow you to access the individual cell. Do I have to get the ItemArray and access the individual cell from that, or is there another way. In VB there was the "item" property. dt.rows[myRow].item[2] = "Fred" If I have a Datarow is there a property that tells me the index of that row in a DataTable? Likewise, if I have a DataRowView Row, is there a property which tells me the index of that row? Thanks in advance for your assistance!!!! Tag: Using OracleType.Clob Parameter ? Tag: 76329

 - optimistic concurrency In the .NET Data Access Architecture Guide, under Performing Database Updates with DataSets | Managing Concurrency, it says there are four main approaches to manage optimistic concurrency when updating through a DataSet: 1. Including only the primary key columns 2. Including all columns in the WHERE clause 3. Including unique key columns and the timestamp columns 4. Including unique key columns and the modified columns Then it goes on to say that 1, 2, and 4 are not recommended -- even though 2 is the default behavior of the Data Adapter Configuration Wizard, and 3 is NOT supported by the Data Adapter Configuration Wizard. I think "ironic" is the applicable word here. What is a good way to implement optimistic concurrency, then? Is everyone putting a timestamp column in the tables, and leaving the Data Adapter Configuration Wizard to RAD hackers? ;-) Brad Williams Tag: Using OracleType.Clob Parameter ? Tag: 76306

 - SQLDataAdapter SP Generation Hi, I have created an SQLDataAdapter component on my vb.net winform project and stepped through the wizard. In my SQL Database I have a table with fields using user defined data types and not the base data types. The problem is that when the stored procedure gets created by the adapter the parameter's data types did not follow the data type of the table I used in the wizard. Is there any solution on how I could use my user defined data types in my SP, autogenerated by the adapter, w/o actually modifying the SP after running the wizard? Appreciate any help. Thanks.

 - Unspecified error when performing operations on OLE DB data adapters I have 7 data adapters connected to MS Access tables. When I try to 1) Preview Data or 2) Generate DataSet or 3) look at the Mapping collection in the DA Properties I get "Unspecified Error". Plus one of the data adaptors generates a bad Update statement that throws an error message when I try to update after a dataset Merge. None of the other adapters throw an Update error. I have tried reconfiguring, recreating and virtually every property parameter without luck. I have recreated the MS Access table from which the bad Update command is created. I have deleted the entire form containing the data adapters and started over again with the same result. Any thoughts? Best regards, Drew Yallop Tag: Using OracleType.Clob Parameter ? Tag: 76286

 - DB data into a custom list... Hi, As I've decided to use my own custom collections to get data from my DB backend, to a web service, and then to my client frontend, I was wondering if there is a way to directly fill the objects of my collection without first having to load into a DataSet. Could I override the SqlDataAdapter.Fill method so instead of dbAdapter.Fill(dataSet, "site"), I have dbAdapter.Fill(myList, "site"), and then the Fill would simply map the fields of each row onto the object fields followed by adding them to the list? What about SqlDataReader, does that give me any more options? Is this a reasonable idea, or should I get my coat? Thanks in advance Colin B Tag: Using OracleType.Clob Parameter ? Tag: 76274

 - Inserting dates into SQL Server DB I'm running the following code in a C#.NET page and it doesn't enter the values into the DB. I'm certain the problem is to do with the txtBirth field. It allows users to enter a DOB as dd/mm/yyyy and I think it's the slashes(/) that are causing the problem. If I don't enter a DOB in this field then all the data enters into the database without a problem. Any ideas?

 - (Search Tool) Alright Already I Fixed It :) This morning I let the group know that I had finished an application that categorizes posts in the vb.net and ado.net newsgroups and eliminates the trash that we hate to wade through on sites like Google and such. Well I would like to thank the multitude of you that have emailed me informing me of the bug in the datagrid (the scrollbars don't show up unless you resize the form after populating the grid). I knew you would be a tough audience but geez :) Actually I appreciate you letting me know. It is the inital release of this so I expected things like this. The bug is now fixed. The corrected version is 1.06. It should automatically remove your previous version but may not because the installer can be buggy.

Hello,

I'm considering the option of using OracleType.Clob Parameter in .net applications.

1. Is it correct that this Parameter type is supported only under Framework 1.1?
2. Are there any performance problems when using Clob with large strings ?

thanks.

The .NET Managed Provider for Oracle was released after version 1.0 of the framework but it should
still work in this version.

I'm not aware of an performance issues with respect to the CLOB.
