    - InvalidOperationException when changing value in XmlDataDocument I'm using a XmlDataDocument to interface a DataSet. When trying to change the value of a node (I'm actually using InnerXML) I get an InvalidOperationException saying "Please set DataSet.EnforceConstraints == false before trying to edit XmlDataDocument using XML operations.". Is it not possible to make changes in the DataSet without setting EnforceConstrains to false? If I set the EnforceConstraints to false, all values that are constrained may be overrided. I only want to be able to set values that are not constrained. Tag: xmltype oracleclient Tag: 133375

    - Remove association between DataSet and XmlDataDocument I have a DataSet that is not cleared untill the application is closed. But I want to associate a XmlDataDocument to the DataSet several times. If I try this I get an ArgumentException saying that a XmlDataDocument cannot be associated with a DataSet that already has an association. How do I remove this association without clearing the DataSet? Another possibility would be to retrieve the reference to the XmlDataDocument from the DataSet, but such a reference doesn't seem to exist? Tag: xmltype oracleclient Tag: 133374

    - What happened to SqlConnection.BeginOpen? We're building some very high performance database applications, and are trying to use all of the new Async ADO.Net 2.0 features. The problem we're having is that we can't find a SqlConnection.BeginOpen/EndOpen method. We can execute everything using the BeginExecuteCommand, but without the BeginOpen on the connection we end up with lots of deadlocked threads, all waiting for SqlConnection.Open. We looked briefly into MARS for doing this, as that might be an option, but we really prefer the more standard Async stuff as it maps much easier into working with other database provides such as Oracle. To do this with MARS, we would still need this BeginEnd methodology. What's frustrating is that early Whidbey builds, and many old ADO.Net 2.0 articles, refer to these methods so they existed at one point. These methods were obviously removed during the .NET 2.0 RTM process, which seems really strange. Any ideas how to work around this and actually do highly scalable I/O using the Async infrastructure in ADO.NET 2.0? -- Chris Mullins MCSD.Net, MCPD Enterprise http://www.coversant.net/blogs/cmullins Tag: xmltype oracleclient Tag: 133370

    - Oracle connection error when called from web service Hi, I'm having a web service which connects to a Oracle database and gets the results. When running the web service individually the database gets connected and the results are downloaded. I'm calling the same web service from another web service, the Oracle connection is not made, it provides me a exception "ORA-12154: TNS:could not resolve service name". The web services used to work perfectly until for some other purpose i changed the tnsnames.ora file, after that i reverted back with the changes earlier (which was working). But still if there is any problem in tnsnames.ora file, then the first web service should also not get connected to database. I don' t know how it gets connected. Following is the code used, string query = GetQuery( ID ); // Create a Oracle connection. OracleConnection dBConn = new OracleConnection(); // Provide the connection string details. dBConn.ConnectionString = "User Id=XXXX;Password=XXX;Data Source = XXX"; // Frame a Oracle command. OracleCommand cmd = new OracleCommand( query ); // Connect the command to connection for the Oracle database. cmd.Connection = dBConn; try { // Open the connection. dBConn.Open(); } catch( Exception ex ) { } Can anyone provide me a pointer about what is happening and how to solve the same??

    - Executing an sql script on a remote database from Visual Studio .NET 2005 I am connecting to a remote SQL Server database from Visual Studio .NET 2005. I have an sql script located on my machine containing the sql code I want to use to create several tables, and want to execute it. How can I do this from Visual Studio .NET 2005? I do not like designing the database using the designer because sometimes the designer uses different words, phrases things differently, and causes me to be unsure exactly what the properties of the fields in my database are. If anybody know how to do this, please let me know. Thanks. -- Nathan Sokalski njsokalski@hotmail.com http://www.nathansokalski.com/ Tag: xmltype oracleclient Tag: 133367

    - Query works in Query Analizer but not as part of a table adapter I'm trying to run a query to return all of the customers who have not placed an order. This query runs fine in Query Analizer but when I try to run it as part of a table adapter it returns all rows (customers with orders AND customers without orders).

    - DataBindings : wrong data displayed Hello, I'm using databindings to display data from a datatable. When I first fill my datatable, it works perfectly, and displays the current data. If I remove the datatable, and recreate it with new data, it's not working anymore : the displayed data are from the first fill of the Datatable ! (I checked, it's not the same DataTable anymore). Here's my code : SqlDataAdapter sqlda = new SqlDataAdapter("SELECT * From Data",Cnx); if (GlobalDS.Tables.Contains("Data")) { GlobalDS.Tables.Remove("Data"); } sqlda.Fill(GlobalDS, "Data"); txtName.DataBindings.Clear(); txtName.DataBindings.Add("Text", GlobalDS,"Data.Name"); Thanks, Tag: xmltype oracleclient Tag: 133354

    - Creating dataset.xsd file programmatically as dragging table from Server explorer fails Visual studio 2003, MySQL database, MySQL odbc 3.51 driver Is it possible to create the file dataset.xsd programmatically? I'm trying to create my dataset1.xsd file for using with crystal reports. The database is mySQL and the data connection is sat in my server exporer bar. The tables and fields are enumerated correctly in the server explorer, but when i try to drag and drop any item onto the dataset1.xsd designer surface I receive a sql error - "The wizard detected the following problems when configuring the data adapter for "users". Details: Error in SELECT clause: exression near "" Error in FROM clause: near "" Unable to parse query text." If I press OK, then i receive the message - "The following unexpected error has occurred: There were errors dropping "users" onto the designer. The XML schema could not be interpreted from this object. " Im stuck and relatively inexperienced so I don't know where to go from here.

    - SQL Question Hello: I have a SQL question. If this is the improper board to post this question on, please let me know where you would suggest I post it. I have a SALES table with the following schema and structure. ID Status Date -- ------ ---- 1 Open 1-1-2000 2 Open 1-1-2001 3 Closed 1-1-2002 4 Open 1-1-2003 5 Closed 1-1-2004 I want to write a query that returns all the records where it first does a count of all the statuses, identifies where the count status is > 2, then display each record where the status = the status which has been identified as having a count of > 2. So the results I want back are: ID Status Date -- ------ ---- 1 Open 1-1-2000 2 Open 1-1-2001 4 Open 1-1-2003 So I write a query something like this: SELECT count(status), id, date FROM sales GROUP BY status HAVING count(status) > 2 I get a SQL error saying that I have to add "id" and "date" have to be in the GROUP BY clause. But when I put those fields in the GROUP BY, then the count does not calculate right and I get no results back. Could anyone enlighten me as to what I could do to fix this?

    - Using crystal reports with MySQL ADO connector I am a developer with limited database and zero crystal report experience. I am very confused. We wanted the ability to switch database providers easily, so I selected to use ADO components with our application. The database we're developing with is MySQL. I downloaded their MySQL Connector/NET components which are ADO compliant. Using .NET connectors, if we want to switch to another provider, there should be minimal code changes necessary to make it run. It all works fine so far. I connect to the remote database at run time using a connection string read from stored configuration information. Now I need to add reporting capabilities to the application, using Crystal reports, and this is where Im confused. http://support.businessobjects.com/communitycs/technicalpapers/rtm_reportingoffadonetdatasets.pdf This example shows preparing data for use in a web project. Ours is a desktop application. So far I've tried to keep all of this as generic and configurable from config files as possible. The example in the above link uses a wizard to link to OLE DB provider registered on the local pc. This immediately ruins the portability as it's done through a wizard. Is OLE DB the "same" as ADO? Do I need to download and install OLE DB drivers from mySQL's site? I wondered if once you've used this wizard, at later dates you can programmatically change server information. Is that possible? thanks :-) Tag: xmltype oracleclient Tag: 133313

    - Non English Characters Hi, We are developing a small web interface to a local ERP software, which uses SQL Server 2000 as database. The database uses SQL_Latin1_CP1 collation, and the fields are varchar (not nvarchar), however, the main program inserts and reads non-English (Turkish) characters into these columns. However, when we connect to database with ADO.NET, these characters are not read correctly. (The situation is same when I check tables with Enterprise Manager and Query Analyzer) In a past situation (which was about a Win32 application), I have heard about character conversion behaviour of ADO (and many other DB libraries) and solved that problem using BDE instead of ADO, so that the connection is made via DB-Library instead of OLEDB. But this way cannot be applied to my ASP.NET situation, and there is NO way to change database collation. Must I use a ADO.NET property, or use another provider, or maybe another library? Any advices? Thanks... Tag: xmltype oracleclient Tag: 133310

    - Corrupted TableAdapter I have this a Data Set. In that data set I have three table adapters, each has there own queries. For some unknown reason, after I added two new fields to the database and mofified the store procedure to retrieve the new fields, in addition too the other fields it already retrieves, and finally modified the tableadapter "GetAssetsById" to retrieve the new fields the TableAdapter Wizard insists on putting a "GetData" as a Return a DataTable Method even though I have uncheck the box. Now my applications fails to execute. I am getting errors everywhere that uses this tableadapter. Sorry I tried but could not supply the code for the tableadapter.

I find this in both the cases of stopping the service and killing the exe. What can i do to kill the process, because killing SQLPLUS is critical; and because of this problem, two SQLPLUS processes are overlapping with each other, when the next time i start the exe/service.

    - CommandBuilder ConflictOption usage I'd like to use the command builder to create update queries but my database schema uses datetime columns for the last time modified instead of a timestamp. Unfortunately ConflictOption.CompareRowVersion seems to only work if a timestamp exists. The update command seems to be rewritten by the dataadapter update method. I added an event handler for the RowUpdating event and the update command is different inside the handler. I'm guessing the update command is created dynamically for each row. Looks like I'll need to fire up reflector. Tag: xmltype oracleclient Tag: 133285

    - Possible to Select * Into #temp From tblx and read #temp with ado. Hello, I have a complex query on sqlsrv2000 that runs better if I use an intermediate #temp table. I have tried using a dataAdapter, Command Object to da.SelectCommand.CommandText = "Select * Into #temp From tblx" da.SelectCommand.ExecuteNonQuery But I get an error. The goal is to then use that same #temp table in a subsquent query. I am thinking that since I am still on the same connection - the #temp table would persist. But that does not seem to be the case.

    - Calling Oracle proc from C# - must I pass in a cursor? I want to create a simple procedure in Oracle that returns a resultset (a select query). In all the examples I've seen, you have to pass in a "ref cursor" OUT param into the proc from C#. Is there a simpler way to do this? IWO can I not pass anything in, and just declare the cursor in the proc? Or have no cursor, like with SQL Server? Seems pointless to pass in an empty cursor param each time.

    - OleDbConnection + MySQL hanging. Hi, I'm trying to use a web service on my webhotel that has support for ASP.NET 2.0 and MySQL 4.0.18-nt. However, whenever I try to use OleDbConnection, my SOAP call just hangs for a while, then returns with "WebException unhandled - Operation timed out.". I've pinpointed it all the way to happening when I call conn.Open() on my OleDbConnection object. Now I tried to make an ODBC driver for my db too, but it gave the same result. Everything else seems work fine with my web service, but it's not much fun without the database support.. Web Service Code: [WebMethod] public string CheckDb() { OleDbConnection conn = new OleDbConnection(strConn); try { conn.Open(); OleDbCommand command = new OleDbCommand("SELECT * FROM test", conn); command.ExecuteNonQuery(); conn.Close(); return "okay"; } catch (Exception x) { return x.ToString(); } } Just to add, I've tried with both valid and invalid connection strings, tried excluding my username / password to get it to fail, but the result is always the same.

    - DataTable Add Row is slow (especially with empty table) After several frustrating hours, I found a solution to a problem that I've been having with DataTable.Add running very slow when trying to add a bunch of records. I found similar questions posted but no good answers, so I thought I'd post this in hopes of helping someone else. Problem: DataTable.Add is very slow. It may be relatively fast when the DataTable already has some rows in it, but is terribly slow when the DataTable is empty. First, unbind any controls that are bound to the DataTable or dependent DataViews. For example: myDataGrid.SetDataBinding(Nothing, Nothing). Next, before you start your batch Add process, call myDataTable.BeginLoadData(). This turns off notifications that the DataTable normally does automatically when you Add. After you are done adding rows, call myDataTable.EndLoadData(). This turns them back on. myDataGrid.SetDataBinding(Nothing, Nothing) myDataTable.BeginLoadData() ' Add a bunch of rows here... myDataTable.EndLoadData() Good luck.

    - Compare datasets with hash values or possibly another method? I have two datasets with the same exact structure that I would like to compare. I would like to know if there is any difference in the data between them. I don't need to know what the differences are, only that there is a difference. From what I have read about hash values, I thought that I could obtain the hash values of the datasets and compare those. If the hash values were different, I would know that there is a difference in the data in the datasets. I tried this approach, but I found that even when I changed a string in one of the fields in one dataset, the hash values calculated were the same. I am not sure if I am missing something here??? This is the code I performed on both datasets to get the hash values... ' Create a new instance of memory stream Dim ms1 As New MemoryStream Dim formatter As New BinaryFormatter 'Serialize dataset to memory stream formatter.Serialize(ms1, dsCurrent) 'Compute hash value for stream Dim hashvalue1 As Byte() = CType(CryptoConfig.CreateFromName("MD5"), HashAlgorithm).ComputeHash(ms1) Then I changed the hash byte array to a hex string... Dim i As Integer Dim sOutput1 As New StringBuilder(hashvalue1.Length) For i = 0 To hashvalue1.Length - 1 sOutput1.Append(hashvalue1(i).ToString("X2")) Next Dim strHashValue1 As String = sOutput1.ToString I then compared the hex strings. Is there another way other than hash values that I could use to compare the data in the datasets? I tried dataset.merge and found that when merging the second dataset into the first, the rowstate of the rows that were different between the two datasets did not change to 'modified', but remained at 'unchanged'. Any help would be greatly appreciated!! Thanks!

    - 2.0 Auto Id in typed datasets Hi, I'm still strugling with the following situation. I've got two table which are related by a foreign key contraint. These table reside in a typed dataset. I working on a webbased app, so a disconnected environment. Now, when I add a row to the parent table and add rows to the childtable (think of customer and orders). This means that I have to use the autogen. id of the parenttable and use this Id as de FK for the childtable. Then when updating the database, I have to retrieve the new Id from de customer table from de db and use this id to update the FK in the childtable before I can add the rows to the db. In 1.1 for this I used the RowUpdating and RowUpdated event. The above example is very basic, in my situation I had to update multiple depending tables. This forced me to use the RowUpdating and RowUpdated methods. I als used the dataadapter.update to update the typed dataset. I can not rely on the Id generated by the typed dataset, because an other person can also add a customer and orders at the same time. To uniquely create an Id, I set the prim.key in the parent to a seed of -1 starting from -1. The neg. numbers are replaced with the new db Id as described in the example above. Now, do I have to use the same construction in 2.0 or is it better to use tableadapters instead? If yes, how can I use them in such a way the same functionality is there as in my 1.1 app?

Kind of like how we get the connection string from web.config into a datasource object, like: <asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:spg_portalsConnectionString %>" Can I do: <SelectParameters> <asp:Parameter Name="dept_id" DefaultValue="<%$ AppSettings:dept %> </SelectParameters> Tag: xmltype oracleclient Tag: 133252

    - TableAdapter specifing 'IN' in the where clause for list of id's Hi, I have a table that contains an interger primary key. I want to query the table for rows that have values equal to a list of ID's that I specify. The sql that I would use would be something like the following: SELECT FunctionalGroupId, ReportId FROM FunctionalGroupReportXRef WHERE (FunctionalGroupId IN (@Ids)) When I specify this query in the TableAdapter wizard the wizard typecasts @id to an interger. Thus I can only specify one id in my query rather then a list of values. I would have expected @Ids to be a string thus allowing me to specify a list of id's. How can I get around this issue? Any help would be appreciated. Thanks!!! Tag: xmltype oracleclient Tag: 133249

    - DataGridView or something else from what I read & tried, DataGridView was meant for Window Forms, not for ASP/Web pages... correct? While I can use it to display data, I can't seem to figure out how to edit the cells... I'm not looking to put edit buttons on each row... I'll go back to regular window forms before I create such an interface.. So is it true, in ASP.Net using the DataGridView, I'm not going to be able to use that control to edit data? Is there such a control I can use in ASP.Net? Tag: xmltype oracleclient Tag: 133244

    - how useful DbCommon namespace? I am working on an application where the end user will select the type of datastorage to use (SQL, Oracle, Access, even Excel for some readonly data, and maybe more providers ) The application reads/writes data and even must be able to create tables in databases (or even create databases) as needed. I am trying to use the new DbCommon namespace in ADO 2.0 to keep the database code as generic as possible. However, as we all know, there are many nuances between the common data providers that make this difficult. For example date formats in queries are different (JET, at least before Access 2003, requires '#' delimiters), cultural settings can work differently with Access/Excel JET (m/d/y or d/m/y). Syntax for creating tables are also different (nvarchar(1000) crashes in JET because text fields in JET are limited to 255 characters so you must use MEMO). So, while I can write a lot of DB independent code, I need specifics in many cases. While working to this end, I can't even find a simple way to query a connection to see who it's driver is!! I've used if (conn is System.Data.SqlClient.SqlConnection) ,is there a better way? I've also written query formatters for date parameters. Who out there has a little more experience to share? Some tricks, pitfalls, links to good provider comparision imformation, anything would be helpful! Tag: xmltype oracleclient Tag: 133240

    - multidimensional array and data table help In vb6, I used getrows to load data into a multi-dimensional array. Since ADO.NET doesn't have getrows, I've succesfully loaded the same data into a datatable. How do I reference the data in the data table as a multi-dimensional array for (row and column), or load the data into an array from the data table? Or is there a better way to do this?

    - SQL Server 2005 Express connection error? When I run the code below in Visual Web Developer 2005 Express, I'm getting an "Unable to find the requested .Net Framework Data Provider. It may not be installed." error. I've been researching a fix for the past two days without any luck. I've tried completely uninstalling both VWD and SQL Server 2005 Express and reinstalling. I've checked for capitalization and typos (code compiles fine). I've also looked at the machine.config file, although I really don't know what I'm looking for to be honest. There are lines in there for "System.Data.SQLClient," although they don't use the same capitalization. Anyone out there seen this issue before and have a fix? If not, can someone enlighten me as to how to troubleshoot it? I'm just beginning in C# and SQL Server, so any info would be greatly appreciated. Anyway, here's the code that's throwing the error. It's the "DbProviderFactory factory = DbProviderFactories.GetFactory(dataProviderName);" line. public static DbCommand CreateCommand() { //Obtain the database provider name string dataProviderName = MyProjectConfiguration.DbProviderName; //Obtain the database connection string string connectionString = MyProjectConfiguration.DbConnectionString; //Create a new data provider factory DbProviderFactory factory = DbProviderFactories.GetFactory(dataProviderName); //Obtain a database specific connection object DbConnection conn = factory.CreateConnection(); //Set the connection string conn.ConnectionString = connectionString; //Create a database specific command object DbCommand comm = conn.CreateCommand(); //Set the command type to stored procedure comm.CommandType = CommandType.StoredProcedure; //Return the initialized command object return comm; } -Josh Nikle Tag: xmltype oracleclient Tag: 133219

    - Using a DataTable instead of a DataReader I've gotten quite comfortable using a DataReader to grab a single value from a table as in the following: Public Shared Function IsUserAdmin(ByVal strNUID As String) As Long Dim dr As SqlDataReader Dim conMembers As SqlConnection = MembershipDB.GetMembershipConnection() Dim cmd As New SqlCommand("SELECT [Level] FROM dbo.user_settings WHERE [Address] = @NUID", conMembers) cmd.CommandType = CommandType.Text cmd.Parameters.Add("@NUID", SqlDbType.NVarChar, 50).Value = strNUID conMembers.Open() dr = cmd.ExecuteReader(CommandBehavior.SingleRow) 'check if the clinical value is 1 If dr.Read Then 'if it is then the user admin privileges 'find out the level Return dr("Level") Else 'if no user is found - it means the user doesn't have any admin rights Return 0 End If conMembers.Close() conMembers.Dispose() conMembers = Nothing End Function I would like to practice using DataTables but I need a little help getting started- could someone tranlate this same functionality (above) for a DataTable?

Definitely not in Visual Studio 2003 (Framework 1.1). I have not tried in
.NET 2.0, however. The ODP.NET download, from Oracle, should have the bits
necessary, however. You can join Oracle technet (otn.oracle.com) and
download it for free.
