I have a limitation in using the BULK INSERT or BCP,
It is a text file of unicode characters with txt extension.
Actual file information will start from
fifth line and it will end before the last second line.
Business logic has to be implemented like validating the
format of file and validating the values of the field,
due to these type of requirements I prefered to apply
regular expressions from front end and formatted values
are converted into XML strings.
I 'am using SQL Server 2000, and .NET 2.0
Can you please suggest me with better method to follow.
Thanks
Valan.

How about, instead of converting data to XML, changing the TXT file format (and performing all the necessary validation), so bcp/BULK INSERT can process it?

Mr. Chopeen,
Are you sure by using the BULK INSERT I will be able to reduce the
execution time, then I will try in all the possible ways to use
the BULK INSERT to complete my File Parsing.
Is that only the better and best way for inserting records into the
DataBase?
Please suggest me.
Thanks and Regards
Valan

A completely different idea just came to my mind - you are using some kind of .NET application to generate the XML file, aren't you? Can't you change it and generate INSERT statements? Then you will have to simply execute those INSERT-s.

Ok Fine thanks I will try to do with your suggestion.
But any Idea why it has to take a longer time for XML
execution.
Thanks and Regards
Valan

I don't have much experience with XML so I'm not sure I will be able to help, but if you post your stored procedure I'll take a look.

I have recently been using sql server 2005 and cannot find how you set the default directory to save your sql scripts. This was in the options and called "Query File Directory" in sql 2000.
Thanks, Jared

That would not be nice for your users. Imagine, you are working along and wham database session is killed and you lose work.

I second that, those type of tasks are usually scheduled for when people are not working.

The only way I can think to end all the sessions would be by stopping the SQL service and then restarting it, your users might open their session again by the time you have started restoring though in which case it will still fail.
You could just run the command "NET STOP MSSQLSERVER" and then "NET START MSSQLSERVER" within your application.
There probably is a better way though but like the others said, it's probably not a good idea.

You can put the database into a mode where only a single connection is allowed at a time by using ALTER DATABASE db SET SINGLE_USER. Use the WITH ROLLBACK option to tell SQL Server when to rollback/abort any other existing connections. The connection you run ALTER DATABASE from remains connected.
You may also be able to restore the database if you take it OFFLINE.

I am trying to insert Data in SQL Database using C#, it's not giving any error but at the same time no rows are getting updated in my database.
private void Button1_Click(object sender, System.EventArgs e)
{
SqlConnection myConnection = new SqlConnection("server=sbs;database=bansal;Trusted_Connection=Yes");
SqlCommand myCommand = new SqlCommand("InsertCategory", myConnection);
myCommand.CommandText = "InsertCategory";
myCommand.CommandType = CommandType.StoredProcedure;
myCommand.Parameters.Add(new SqlParameter("@CategoryName",SqlDbType.NChar, 15));
myCommand.Parameters["@CategoryName"].Value = "Ambarish";
myCommand.Connection.Open();
try
{
myCommand.ExecuteNonQuery();
}
catch(SqlException e){}
myCommand.Connection.Close();
}
Following is the Stored Procedure:
CREATE PROCEDURE InsertCategory
(
@CategoryName nchar(15)
)
AS
INSERT INTO Categories (CategoryName) VALUES(@CategoryName)
Table Name is Categories and has two Columns only:
1. CategoryName NChar 15
2. Identity Int 4 (Identity Seed is 1 starting from 1)

You are adding a parameter to the command every single time you press the button. You now have several parameters - which one does the database use? It will use the first one with the correct name and ignore the others. You most likely have a parameters set up by the wizard that created your connection with the database.
This is the big problem with using these wizards - they hide what is really happening. Don't use them. They should never be used. Write your own database code, and write it in a DAL (Data Access Layer) class.

Dear Sir,
Thank you very much for your quick reply. I would like to mention that these lines have been coded by seeing Microsoft Help and I have not used the Wizard for creating this.
The problem that this code doesn't give any error, but at the same time data is not inserting in table.
Please help me in this regard.
Thanks,
Sachin Jain

Okay - it looked a bit like you were using wizard created code, but on looking again it doesn't seem to be the case anymore.
sacheesach wrote: The problem that this code doesn't give any error
It probably does but you are using the anti-pattern known at try-catch-ignore which is summed up by this line in your code:
catch(SqlException e){}
Comment out the try and catch statements to run the code inside on its own. Does the debugger point out an error?

Sir,
Thanks for your suggestions.
It was a silly mistake committed by my new programmer. In fact the Permissions (Select, Insert, Delete, Update etc.) on the Categories Table were unchecked and this was the reason the error was given.
Thank you again for your kind support.

Hi!
Hope every1 is doing fine. I am having an issue with database, i am using SQL Server 2000 and Asp.Net (VS.NET 2003) to develop my application. There is a scenario in my application where i need to compare rows of a table with each other and if they match then store its one copy in another table and delete both copies from first table.
Problem is that the table contains more than 50 fields (columns) and if i try to compare each column through query it will take hell of a time...i was wondering if there is any builtin funtion or some technique through which i can compare two rows without writing lengthy query.
Also i want to keep track of those fields of table which does not match and stotre their information in another table.
Any kind of help is appriciated...thanks in advance!

Affan Ahmad Toor

How it should match ? All columns should match or only some columns. I presume that it should match all cloumns. Writing a single query that does all theses things seems impossible to me. You can do this using cursors.
Declare YourCursor Cursor For
Select Coulumn1,Column2,Column3..... from your table
Open YourCursor
FETCH NEXT FROM YourCursor into @Columnvar1,@Columnvar2...
WHILE @@FETCH_STATUS <> -1
BEGIN
--Select rows from table and insert to new table
Insert into newtable
Select columns fom table where column1=@Columnvar1, column2 = @Columnvar1
FETCH NEXT FROM YourCursor into @Columnvar1,@Columnvar2...
END
Close YourCursor
deallocate YourCursor
select * from newtable
This may insert duplicate rows into newtable. You need to refine the code to make it work for you.

 HI,
Do we have a tool to capture requests made to a Syabse Server, same like SQL Profiler.

Have you looked around at Sybase? I don't know much about Sybase, and I cannot really help you other than recommending looking at Sybase's resources.

hi, what is the difference between SQL 2005 32bit and 64 bit and which one should i install
|
|
|
|
|
The 32-bit edition can only use up to 2GB of virtual address space on 32-bit editions of Windows (3GB if the OS is booted with the /3GB switch but it's not recommended), or 4GB on 64-bit editions of Windows. SQL Server supports the 'address windowing extensions' feature which allows more physical memory to be used, but it's not particularly efficient.
The 64-bit editions (there are separate editions for AMD/Intel 'x64' processors - all new Athlon 64, Opteron, Core 2 and Xeon processors are - and Intel Itanium processors) can use a huge virtual address space - 48 bits' worth.
In general, if you've got a 64-bit computer with the 64-bit OS, you should install the appropriate 64-bit version of SQL Server. If you have an Itanium system, you'd know about it and you wouldn't be asking the question!
