    - Query Timeout Expired Using SELECT/WHERE All, I am using C# to a SQL Server 2005 database using an SqlDataAdapter, SqlCommand and SqlDataReader. When running the query I receive the following exception: "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding." Does anyone know how to increase the timeout value for a query? Thanks in advance, Scott Tag: Error: Pending Requests working on this transaction Tag: 128392

    - DataReader .HasRows but returns 'Invalid attempt to read when no data is present' error Hi, I am using a stored procedure to extract data from an SQL server database using a datareader. The datareader .HasRows returns true, i have also checked this with query analyser, but when i attempt to use a returned value to SelectValue in a combobox I get the error 'Invalid attempt to read when no data is present'. How can this be when .HasRows is true? Here's the relevant code: SqlCommand cmdLesion = new SqlCommand ("proc_SelectLesion", conn); cmdLesion.CommandType = CommandType.StoredProcedure; cmdLesion.Parameters.Add(new SqlParameter("@patientNo", strPatientNo)); cmdLesion.Parameters.Add(new SqlParameter("@lesLocation", strLesionLocation)); conn.Open(); SqlDataReader dr; dr = cmdLesion.ExecuteReader(CommandBehavior.SingleRow); if(dr.HasRows) { lesionLocationCboBx.SelectedValue = dr["lesNo"].ToString(); } else { lesionLocationCboBx.SelectedIndex = 0; } dr.Close(); And the stored procedure "proc_SelectLesion": CREATE PROCEDURE proc_SelectLesion (@patientNo int, @lesLocation varchar(50) ) AS SELECT lesNo FROM tbllesion WHERE lesLocation = @lesLocation AND patientNo = @patientNo GO Any ideas?

    - DataSet ReadXmlSchema doesn't support <xs:any> If someone could please confirm this is a problem or notify me of a work-around I'd really appreciate the help. I've pulled some hair out on this one. I need to support an Element in the Xml schema that can support any XHTML element as defined in the namespace "http://www.w3.org/1999/xhtml". I've used the <xs:any> element as you see in the sample schema below. When using ReadXmlSchema() to load this .XSD file I see the DataSet has two tables. One for Person with firstName and lastName columns. The second table is titled htmlstuff with a column to link to the parent Person record ("person_Id"). I need to either get the ReadXmlSchema() to add a column such that I can push xhtml content into the Dataset or add it manually so it complies with this schema. Any suggestions? Here's a schema: <xs:element name="Person"> <xs:complexType> <xs:sequence> <xs:element name="firstName" type="xs:string" /> <xs:element name="lastName" type="xs:string" /> <xs:element name="htmlstuff"> <xs:complexType> <xs:sequence> <xs:any namespace="http://www.w3.org/1999/xhtml" maxOccurs="unbounded" minOccurs="0" /> </xs:sequence> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> Tag: Error: Pending Requests working on this transaction Tag: 128371

    - Shot in the Dark Is it possible to populate a datatable with the contents of a string variable? It's not in xml format, but instead it is the contents of a csv. I realize I'm grasping, and I did several searches online and found nothing, but I'm thinking there must be some way to combine things like streamreaders with data adapters, or some such thing.

    - Comparing DefaultValue to DataRow column values The code below should it seems to me work but doesnt: bool rowChanged = false; foreach (DataColumn col in row.Columns) if (col != row.Table.PrimaryKey[0]) if (col.DefaultValue != row[col]) rowChanged = true; When debugging it I found that for a bool type column whose DefaultValue is true and whose row[col] value is true, the code goes into the last if statement and sets rowChanged to true. When I get VS.Net Command window to print out the value of (col.DefaultValue != row[col]) it even says false. However somewhat suspiciously the full dump of the variables col.DefaultValue and row[col] are different although they imply their values are the same. I seem to remember something about DataRow column values being held in types which allow for a DBNull.Value value. So I may be trying to compare two different types here I suspect. However I can't find any way of cooercing an object into another type where that type is held in a variable something like this: System.Type tp; object x = (tp)row[col]; I've had to write some hideous code which deals with all the different possible types on a case by case basis. Anyone got a better idea? PS anyone who writes a reply asking why I want to do this without suggesting any solution will get flamed Tag: Error: Pending Requests working on this transaction Tag: 128363

    - .Net Reporting against Oracle Here's my issue. We've decided to replace a very critical (without it the business would lose lots of money) departmental reporting system with a built from scratch system based on .NET. The key component is a datagrid (it really turned the CIO's head). The issue is that the data source is Oracle. We've got a very complex reporting system that produces dynamic sql and sends it to oracle and takes back the result set and displays it. Each report has at least 3 filters and some more than a dozen. Each filter can either be a single item, a list of 1 to N items or left blank. The idea is to push this into Oracle stored procedures and get back a refcursor. The filters/parameters effect not only the where clause, but can effect the select clause, the from clause (what tables are queried) and when either the from clause or select clause are effected the group by clause is effected. This is a complex database (not large by data wharehouse standards) with indexes and structure that are not friendly to reporting. Speed of the reports is a critical issue. It's something we've fought pretty sucessfully in the old system. We've also got to have a batch component. That is a number of reports need to run overnight and be available first thing in the morning. This can't be just a single job that runs a bunch of reports. We need each report to run separately. Oh and it needs to not start before certain jobs are finished on the Oracle database. Oh we've got a schedule of six months - nine months max and the clock is ticking. For the first issue. Has anyone done something similar. If so any key problems with this (forget buy crystal, cognos etc. It's not cost they are rounding error in our bottom line, but that decision is pretty set also forget a data wharehouse - no time) Second issue - does anyone know a good scheduler that will integrate well with a .NET solution. Thanks in advance. Tag: Error: Pending Requests working on this transaction Tag: 128354

    - Run SQL comand with String from SQL Script Using SQL 2005 I generated a SQL Script to create a DB Table and columns. in VB.NET i use the StreamReader to read this file to a string, and I want to execute the script in my application, so the app can create an identical table at runtime. Obvously if i simply run the SQL Script from the file, it works, and if I copy the StreamReader String while debugging into a SQL query, it also works (creates the table) fine. However, when the program steps to the SqlCmd.ExecuteNonQuery( ), I get a SQL Exception, "Syntax error near....". The sql script (and command string) are very long, (Many tables, many properties... many "Syntax error near"). I've tried to Replace single (apostrophe) ' with '' and even single (quote) " with "", but the same result. How come if I paste the string directly from the app to the query analizer it works, but errors out in the app? Any suggestions?

    - Updating multiple records Hello, I want to know an efficient of updating multiple records in a .NET datatable into a Oracle 9i databse without making multiple trips to the database. That is, i want to know if Oarcle 9i can take the whole set of records in the datatable in a stored procedure(in the form of XML or arrays) and update records internally by looping through the records. I want to acheive this using the OarcleClient that come with .NET 1.1. I am currently experiencing huge delays(30 minutes) when i try to update around 15000 records through the DataAdapters.Update method (I think the delay is due to the fact the stored procedure is invoked for every record). The database is in our intranet and is properly indexed on the update table. Any thoughts on this? I apperciate your help!

    - OracleConnection passing different application name I'm writing a web service that is executing a stored procedure on an Oracle data server. One of the things that this stored procedure does is to keep track of 'who' is using it by storing some information from the V$SESSION view. One of the columns being tracked is the client program name. But, what I'm getting is the name of the web service, but what I really want is the name of the program calling the web service. Part of the framework that we have developped passes the calling program name, so, I have that. What I don't know is how to pass that program name instead of the web service program name. Does anyone have any ideas on how to do this? For instance is there an undocumented keyword/value pair that can be passed as part of the connection string. Or can I change the program name attribute of the service? Thanks -- Jim Noeth Tag: Error: Pending Requests working on this transaction Tag: 128323

    - Joins on many tables Hello I have one central table in my db, with a lot of related tables (many to many relations). I need to do some searches, on the central table and it related tables. Previously it has been done by pulling everything up in a dataset and adding a rowfilter. This could be done because previously the app worked offline by pulling everything into a dataset, and working on that dataset and in the end submitting it to the database. I have now been working on making the app being "more connected" meaning that searches are being done directly on the db, and the data being submitted instantly instead of waiting till the app shuts down. Now as I mentioned i have to do the search in sql somehow. But I have to do a lot of JOINs, and I am rather new in this area. So could someone please point me in the right direction, do I need stored procedures, views or something else? Thank you in advance.

    - SqlBulkCopy and column mappings Hey, I'm replacing an old C++ DLL in our application that used BCP with an SqlBulkCopy alternative. The problem Iâ??m having is that the column mappings seem to compare the destination column with that of the actual table and fails when there is a difference in case. This comparison seems to be performed based on the current thread culture rather than the database collation. The old BCP implementation on the other hand was either case insensitive all the time or obeyed the database collation. Is there a way to either take into account database collation or temporarily change the CompareInfo on the threads current culture to perform case insensitive string comparisons? Thanks. Steve.

    - ado.net and sql 2005 We have been testing a migration of our application from 2000 to 2005. All seemed well until last week. Our framework generates a set of business objects and maps them through a DAL to a specific table/column. In Sql Server (we also support Oracle) our columns definined by the developer as currency (internal type name) map to a .Net 1.1 decimal type and a sql server table column of money. From my understanding these columns have a default scale of 4. In Sql 2000 (and oracle) when we perform a data adapter fill (sp_execute), the decimal type is truncated down to 4 decimal places. Thus 34.3456432 gets truncated down to 34.3456. This is fine with us because the excess precision is a result of cost calculations and we have no interest in keeping the info. The money type is stored correctly and our clients are happy. YET... now in 2005 we get an exception passing the value. It complains about exceeding the precision but I was under the assumption for a money type that the precision was thirty something... ------------------------------------------------------- Unable to apply changes to the DataSet (SqlException):The incoming tabular data stream (TDS) remote procedure call (RPC) protocol stream is incorrect. Parameter 5 ("@AREAAVGCST"): The supplied value is not a valid instance of data type numeric. Check the source data for invalid values. An example of an invalid value is data of numeric type with scale greater than precision Here is the value: 5.9232811750188790881984289485 --------------------- What is going on? We have a client going live on 2005 and this makes no sense. Are we supposed to check every decimal to see if it exceeds the column precision?

    - Transactions with generated DataAdapters Hello, I have generated a DataSet with Visual Studio 2005 by selecting Data -> Add New Data Source ... -> Database etc. from the menu and selected 2 objects (tables) in the Data Source Configuration Wizard. As a result I get an .XSD DataSet file that automatically generated a DataAdapter. I have added an insert statement to both tables. Question 1: One table has an autonumber id field that automatically generates a primary key when inserting a new row into the database. How do I get that automatically primary key which I need for the insert statement in the second table? Question 2: Both insert statements should be performed in one transaction. How do I set up a business method for inserting values into both tables that executes both insert statements in one transaction, i.e. public void insertValues() { MyFirstDataSet.MyFirstDataAdapter a1 = new MyFirstDataSet.MyFirstDataAdapter (); MySecondDataSet.MySecondDataAdapter a2 = new MySecondDataSet.MySecondDataAdapter (); // start transaction a1.InsertValues("mike", "miller"); // a value is inserted into a table with autogenerated primary key int key = ... a2.InsertValues(key, "test"); // end transaction or rollback } Any help would be much appreciated.

    - Table name's in Dataset Hello Guys, I have a proc which returns variable number of tables. I want to do some validations on these tables and dont want to use the index (e.g Dataset.Tables(0)) to refer to the table, I want to use the tablenames instead. I cant do a tablemapping either caus I dont know which table will be returned at which position. Is there a way to get the table names returned by the proc in the dataset instead of the default names like Table1, Table2 ... Thanks in advance...

    - Help! Something adds 1 hour to my datetimes! :-S Hi, For some reason, somewhere in my application 1 hour is added to my dates, depending in which time zone the application is run... Because I don't have a clue where this happens, I posted this to the three relevant newsgroups (vb/ado, sql and xml): my aplogize for this. I'm doing a Synchronisation between two SQL Servers (2000): All the Data is read into a DataSet, and exported to an XML-file: SQL Server -> DataSet (VB.NET 2003) -> XML -> DataSet -> SQL Server When I run everything in the West Central Africa Timezone (GMT+1, no summer-time): everything works fine. But I notice that all my dates in my XML-file are written like this "<DATE_DEB_APP>2006-02-01T00:00:00.0000000+01:00</DATE_DEB_APP> ": with the "+01:00" at the end. But not that big of a problem, because the application writes the date with 00:00 hours to the database. I (well, my pc) is in the Brussels Timezone (GMT+1: but because of the summer-hour we actuallt have GTM+2 now). Everything goes fine also when I put the databse on my local SQL Server, make the XML-file, read it again, and write it to the other database (also local). All the dates are also presented with the "+01:00"-suffix. Except one: a date that the application writes to the database when filling the DataSet, and select it at the end to put it in the XML-file also: this one gets the suffix "+02:00": <SyncSend>2006-05-03T09:58:19.6070000+02:00</SyncSend> So far so good: some not-really wanted things, but everything goes fine. Problems start when I'm doing a synchronisation between an SQL server in Central African TimeZone, and a local one in Brussels Timezone. What hapens is that all my dates are having 1 hour added to them! So instead of the "2006-02-01T00:00:00" they have as value "2006-02-01T01:00:00"!! I somehow can understand why this happens; because 00:00h in Central Africa is 01:00h in Brussels on this moment. But I don't want it to happen! I want the exact time to be transfered! Does anybody has a clue where this exactly happens? And how to prevent this? Is there a way to say that it has to use the actual value? and not one that calculates the time? On this moment it's really nice to be able to use tha capbilities of the DataSet with the XML-files and SqlDataAdapter with commandbuilder to do my insert and updates. I won't really like to loose this :-S Thanks a lot in advance! Any help our hints would be really appreciated! Pieter Tag: Error: Pending Requests working on this transaction Tag: 128225

    - update tabledefinition using dataadapter and datacolumn Hi everybody! I'm trying use the datacolumn class to create new columns in a datatable object and submit the new created column to the database (Access 2000). Here's the code: Sub Main() Dim oconn As New OleDbConnection("Provider=Microsoft.Jet.OleDb.4.0; Data Source=C:\test.mdb") Dim adapter As New OleDbDataAdapter("SELECT * FROM Cities", oconn) Dim mydt As New DataTable Dim nCol As New DataColumn adapter.Fill(mydt) With nCol .Caption = "Newcolumn" .DataType = OleDbType.Boolean.GetType End With 'Add column to Datatable mydt.Columns.Add(nCol) 'Write changes to database adapter.Update(mydt) ReadLine() End Sub I know I could use "ALTER TABLE ALTER COLUMN" commands as well, but is there any way to create/update columns to a table in a database using ADO.NET (without using DAO or ADOX) Thanks for your efforts! wkr binder Tag: Error: Pending Requests working on this transaction Tag: 128224

    - VS2005: Bug in Rowchanged event during cascade update? New 'behaviour' in ADO.NET 2.0? In a DataSet, I create a ParentTable with a Primary Key (ParentID). I then create a ChildTable with a Primary Key (ChildID) an a ParentID column. I create a Relation from ChildTable.ParentID to ParentTable.ParentID with both Relation and Foreign Key Constraint and Cascade Update rule. I then write at little program: 1. Add a row to the ParentTable (ParentID = 1). 2. Add a row to the ChildTable, referencing the row in the ParentTable. 3. Add RowChanged handlers to both tables. 4. Update ParentID in the parentRow (parentRow.ParentID = 100); - The ParentRow is updated and the update is cascade to the ChildTable. ChildTable.RowChanged is fired. The problem: In the ChildTable.RowChanged handler I can see the childRow has been updated: ((ChildTableRow)e.Row).ParentID is 100. BUT ((ChildTableRow)e.Row).ParentTableRow returns null !!! If I output ds.ParentTable.Rows[0].ParentID (I only have one row in the table) it is 100. The field has been updated in both tables - but ChildTableRow.ParentTableRow cannot find it. If I call ds.ParentTable.FindByParentID(100), null is returned. When the ParentTable.RowChanged event is fired subsequently, there is no problem with ChildTableRow.ParentTableRow. What is going on? Can anybody help me? Regards, Zach Tag: Error: Pending Requests working on this transaction Tag: 128223

    - Connection string is class module Hello, I put the connection string to the Web.config file, then in Global.asax I'm assigning this string to the application variable: cn = New OracleConnection cn.ConnectionString = AppCrypto.decrypt(ConfigurationSettings.AppSettings("ConnectionString")) Then I use this to variable to connect to the server: cn = New OracleConnection(Application("ConnectionString")) Everything works great with the webforms. However, to keep my connection code in one place, I put all my connection code in the class module. But in the class module this doesn't work! I have to use exactly the same code as in the Global.asax: cn = New OracleConnection cn.ConnectionString = AppCrypto.decrypt(ConfigurationSettings.AppSettings("ConnectionString")) This is not acceptable, because the connection is encripted, and if it gets decripted every time my application connects to the database, it slows things down badly. Why the application variable doesn't work in the class module? Probably I'm doing something incorrectly. The only solution I see now is to drop my connection class and connect to db in the webforms, which is not a smart application design. Is there a better solution? I would appreciate your advice very much. Thank you, -- Peter Afonin Tag: Error: Pending Requests working on this transaction Tag: 128217

    - DataTable.Select - There is no Row at position X -- Exception Hello, I'm facing this problem for a long time from now... I have a datatable that after a set number of rows gets all rows deleted (and archived into a xml) but to not have a clash with id's I set the start index from the datatable to the last id written in the xml plus 1, no problem... BUT... after a lot of deletes and inserts, when I run a .Select statement into a DataTable I get this error "There is no row at position X" where X is a number that really doesn't exist... but I simply run a select statement, not a foreach nor nothing... it's nonsense to look for a data that doesn't exist... e.g.: if my table is limited to 200 entries, after a few selects, deletes and inserts, it starts to return an error at some random position (not sure if is random but absolutely is not the same row) for example, BUT, sometimes, it says that there's no row in a position that has a row... I already debugged and in a few situations, this exception was thrown on the row 10, for example, but looking at position 10 of the datatable I could find data AND ACCESS IT... Does anyone knows something about it? Is some kind of bug...? Am I missing something?! Thanks in advance Tag: Error: Pending Requests working on this transaction Tag: 128215

Exception: System.Data.SqlClient.SqlException: The transaction operation
cannot be performed because there are pending requests working on this
transaction.

ASP.NET 2.0 running on Windows Server 2003 with MS SQL Server 2005

I have a web page that very simply takes a query string and inserts data
into my database.

On the insert there is a transaction. It has been in operation for quite
some time and has never had a problem. It executes two or three SQL
statements and if there are no errors it commits, othewise it rollsback.

For some reason, after the page runs for a while and takes a couple hundred
submissions, it starts giving me the error above. I can't find anything
about this error. I can't see how there could be pending requests working
on this transaction since there is only one call to the database.

How can I diagnose this problem?

Thanks,

James Vitale

Hi James,

This problem might be caused by several insert requests sharing the same
connection. Please check if it is true. If so, try to create a connection
each time you're doing an insert and close it immediately after use. This
might resolved the problem.

I've got this error recently when I forgot to close the IDataReader
while Commiting the transaction. The connection was still opened
however.
