In nutshell, there is DataTable within DataSet. One of DataTable's columns is expression-based. Afer I tried to update database (via use DataAdapter.Update(DataTable)), following exception occured:
An unhandled exception of type 'System.Data.VersionNotFoundException' occurred in system.data.dll
Additional information: There is no Original data to access.
HELP!

Try writing yourself the Update command for the DataAdapter, omitting the calculated column...

Hi,
Environment of web application is: Windows 2000/VB.NET/ASP.NET/SQL 2000
I am passing an XML to the sproc and reading it using OPENXML. There is a date value coming as one of the parameters. Sometimes, the date can be blank.
Now how can I use CASE..END in WITH section to decide, if its a blank then use NULL else pass the incoming date? See the following scenario.
Select *
from OPENXML (@idoc,'/TaskDetail',1)
with
(
ClosedDate smalldatetime 'ClosedDate',
)
Please advice.
Thanks

I have a c# application that does frequent checks to the database to see if a status flag in a table has changed.
After the query, I close the connection and command objects with
connection.Close() and
command.Dispose()
If I look at the current activity in SQL Server, I see each of these queries as sleeping processes that just continue to accumulate. What am I missing that keeps these processes around after the query completes?
If it makes a difference, I am using MSDE.
Thanks in advance,
Bruce

Hi!
I am using sql server 2000. How do I make my DB case sensitive without reinstalling sql server 2k?
Please help me on this.

Reinstalling won't help. You bought the wrong product. You should have purchased SQL Server 2K.

If you just want to change a single database, you need to run an ALTER DATABASE query, e.g.
ALTER DATABASE mydb
COLLATE SQL_Latin1_General_CS_AS This only alters the new default and how object names are interpreted; you'll need to alter any existing tables as well.
If you need to change the default collation of the database server (including the tempdb database), you should run the rebuildm tool. See also KB article 273572[^] about a problem with this tool when the source files are read-only. rebuildm lives in the 80\Tools\binn directory under the SQL Server install directory.
Note that rebuildm and setup use 'friendly' names for the collations, whereas Enterprise Manager and queries use a different naming convention. The names used in setup are listed in Selecting a SQL Collation[^], while the names used in queries may be found under SQL Collation Names[^].
There are two types of collations: those implemented using the Windows national language support functions (Windows collations) and those implemented independently by SQL Server (SQL collations). SQL collations have names beginning SQL.

I have an update string like this:
<br />
UPDATE pms_tools_tasks SET Status='ToDo',Assigned='kluch',Priority='2',Title='Anything',Descript='No',Notes='Just Work',CreateDate=NULL,CompleteDate=NULL,Project='',TicketBased='0',TicketID='0',UserUpdate='',Private='0' WHERE ID=7<br />
Which works fine, But if a user enters any text with an apostrophe like for instance "doesn't work" in the title field. The update no longer executes successfully. What can I do about this?
|
|
|
|
|
Don't know 100% true for mySQL but in most databases, doubling the character tells the database to use the apostrophe as a character rather than the string terminator.
You might explore escape characters as well. Take a look at the docs because you'll want to take into account any of the characters the database treats as "special". Some are treated by doubling the occurrence of the character but others may require an escape character.

How can I cancel the addnew record process when i filled some columns in the last row of the datagrid, and I change my mind and don't want to save the new row to the database? If I cancel the beforeupdate event I am still in the last row, but I want to quit from the last row and clear its columns. How can I do that?
Thanks for any advice!

How to get the current selected row in DataGrid without having to use DataGrid method?
Is there any way by using the DataSet method or properties?
Thank you!

Can anybody suggest a couple good books for ADO.Net? I've found, bought and looked through several but they all tell you how to connect to a database, download the info and then Console.WriteLine() the results.
But what about real world where the data needs to be manipulated, moved, handed off, etc? Getting into the detail of evaluating data within the tables/datasets to determine what changes have been made? Taking a subset of one of the tables and creating a new table and returning only that (no, the situation does not allow the user to do their own filtering). Patience and money is starting to build constraints and unfortunately, I don't have a lot of people here to talk to for C# and .Net.
Just wondering if anybody can suggest a couple good books. I appreciate the help.

Does anyone know of any third party SQL tools for .Net that aid in the development of database applications?
|
|
|
|
|
I can't remember off hand, however, I do remember seeing something on www.asp.net and also on the MSDN website under the DotNET section, not SQL.
|

In the .NET Framework there are two Base Class Libraries OLEDB and SQLCLient. Both of them can connect to a SQL server but OLEDB has togo through a COM Component which takes a performance hit. I was just wondering whether this performance hit is big enough to make me not want to use OLEDB and strictly use SQLCLient.
|
|
|
|
|
SQLClient is strictly for Microsoft's SQL Server. If your using MSSQL Server and you don't need your code to be portable(.NET isn't exactly portable yet), then I would use SQLClient.
|
|
|
|
|
Yes I know that but does OLEDB and SQLClient have a major performance difference?
TIA
