Hi,
I have stored proc in which an SQL query is being executed which may timeout some times. I got that error using the code it is showing one number but when I searched in google for the same, but google is showing another number for query time out.
Now my question is how can I get that the query is timed out. Will that error number be in some limit from this number to this number is for query time out or it changes from OS to OS or does it depends in SQL server version.
Please give me hints about it sot that I can show the appropriate message to the user in exception. I would be very much thankfull to all of you.
Thanks,
Aleem Mohammad.

What was the error number you got and from which SQL Server version?

Hi,
The error number that I am getting from the program is : 2147184992 and in google I am getting another number.
Which should I take. And how should I resolve this issue.

That number sounds more like the HRESULT.
When the exception occurs, have a look at Number and Message properties of the SqlException.

Yes I understood that, but the question is from what property of a SQLException did you take the number? If you took it from ErrorCode, it is not the number for the error, but only a handle to the result which will change every time.
Is the number you posted taken from Number property of a SQLException? Refer to: SqlException Members[^]

I would have thought this is a client issue, the error and the text of the error is available in VS and can be reported through normal error trapping. I know this as we get timeout errors every day, they are reported and someone gets slapped for running parallel processes.

You cannot have a case statement for the sort. You can either have multiple selects, create dynamic sql, or let your application sort the data.

I'd do this in 2 steps, the first being to put the results into a temp table with an additional column named 'sort_by' in the Select list. This column will be the value to sort by, but you'll have to cast to a common denominator, so to speak (looks like it cold be numeric, character, or datetime). So, you'll have the following new field for your query:
select *,
CASE @Sort_by
WHEN 'Order No' THEN cast(ORDER_NO as varchar)
WHEN 'Vendor' THEN cast(v.Vendor_Name as varchar)
WHEN 'Date' THEN cast(p.order_date as varchar)
END [sort_by]
into #temp
from ....
So the results of the query will then be in a temp table, let's just call it #temp. Then all you would need is an IF to select all the records from #temp to apply the ASC or DESC sort:
IF @Sort_order = 'Ascending' THEN
BEGIN
select * from #temp order by [sort_by] asc
END
ELSE
BEGIN
select * from #temp order by [sort_by] desc
END
If you don't want the [sort_by] field in the result set, replace 'select *' with a field list of each field except the [sort_by] field. Don't forget to drop the temp table, or use a table variable instead.

But is this method fast because on every click on search button in asp.net, it will generate a temp table.

The performance of my previous suggestion would depend on how large you anticipate the dataset to be. If you really wanted to shy away from using a temp table, you could wrap the first query inside another query that will do the sorting with no temp table. The idea would be kind of like this:
IF sort_ascending THEN
BEGIN
select t.*
from (select ..., case when ... [sort_by] from ...) t <--- this is the main query
order by t.[sort_by] asc
END
ELSE
BEGIN
select t.*
from (select ..., case when ... [sort_by] from ...) t <--- this is the main query
order by t.[sort_by] desc
END
The 'select t.* ...' query just selects all the fields of the main result set and then applies the ordering to it.

Presumably you have passport number, name etc in specific fields, so a satndard select should do it for you.
As for the rest, you either write the code yourself and ask specific questions or hire someone to do it. This is not a free code shop.

hi i have a dataset which consists of one tables. i need to filter this data set and store it in another table. how can i do this?

Easy
Select * into newtable from oldtable where 1 = 2 -- create empty table
insert into newtable select * from oldtable where ....
Although you can do select * into newtable from oldtable where.. this is bad practice as it locks the system tables for the duration of the query.

Hello all,
Is there an easy way to copy a record from one database to another database (that have the exact structure) in sql server 2000 using c# ?
The record have some Foreign keys with the other tables in the DB.
The only I could think of is to export the record to a xml file, and then import that xml file to the destination db.
thank,

I am using SQL server 2008 in one comp and if i want to bakup the database and use it in sql 2005 it is showing some errors like format not compatable.

Restoring a backup to SQL Server 2005 which is taken from SQL Server 2008 isn't possible. The format is simply different.
One way to overcome this is to build an extra SQL Server 2008 instance, restore the backup there and then for using for example Export/Import you transfer the schema and the data from 2008 to 2005. There are several tools and options which you can use for the transfer (SSIS, scripting the database, bcp etc)
The need to optimize rises from a bad design.

Restore a SQL Server 2008 Database into SQL Server 2005
If you've tried to back up a database in SQL Server 2008 and then restore it into SQL Server 2005, you know that the database backups are not backward compatible. However, with SQL Server 2008 Management Studio, you can script data and schemas in SQL Server 2005 mode. This 10-Minute Solution takes you through the steps to back up the Northwind database on SQL Server 2008 and restore it to SQL Server 2005.
The Problem:
Transferring databases from SQL Server 2008 to SQL Server 2005 is not possible with standard backup and restore facilities.
The Solution:
Leverage the scripting wizard in SQL Server 2008 to script data as well as schemas in SQL Server 2005 compatibility mode.
Using the "Generate SQL Server Scripts" Wizard
The Northwind database is no longer shipped as part of the SQL Server installation, but you can download it from go.microsoft.com. The data is scripted as INSERT statements.
To create the scripts, you have to run the "Generate SQL Server Scripts" wizard, which you can run within SQL Server Management Studio (once Object Explorer is connected to the appropriate instance) by right clicking on the database and selecting "Tasks –> Generate Scripts."
Figure 1 shows the initial dialog to the wizard. Click "Next" and complete the following steps in the wizard to back up the Northwind database on SQL Server 2008 and restore it to SQL Server 2005
Figure 1. Initial Dialog to Generate SQL Server Scripts Wizard: To create your scripts, you have to run the "Generate scripts" wizard.
Click "Script all objects in the selected database" (see Figure 2), and then click "Next."
Figure 2. Select Database Dialog: Click the "Script all objects in the selected database" option.
Amend the script options: Specifically, set "Script for Server Version" to "SQL Server 2005" and set "Script Data" to "True" (see Figure 3). (SQL Server 2000 is also supported.) If you are putting the database on a new instance for the first time, make sure the "Script Database Create" option is set to "True." Click "Next" when you are happy with the options.
Figure 3. Choose Script Options Dialog: Set the "Script Data" option to "True."
Select "Script to file," select the file name, and choose "Single file" (see Figure 4). Click "Next" for a summary (see Figure 5).
Figure 4. Output Option Dialog: Select "Script to file," select the file name, and choose "Single file."
Figure 5. Script Wizard Summary: Review your selections for the wizard.
Now click on "Finish" to get progress messages while the script runs and completes (see Figure 6)
Figure 6. Generate Script Progress Dialog: Click "Finish" and you will get progress messages.
If the generation process fails, then you can use the "Report" option to see why.
When the scripting is completed, look for the following lines:
CREATE DATABASE [Northwind] ON PRIMARY
(NAME = N'Northwind', FILENAME =
N'C:\Program Files\Microsoft SQL Server\MSSQL10.SQL2008\MSSQL\DATA\northwnd.mdf' ,
SIZE = 3328KB , MAXSIZE = UNLIMITED, FILEGROWTH = 1024KB )
LOG ON
(NAME = N'Northwind_log', FILENAME =
N'C:\Program Files\Microsoft SQL Server\MSSQL10.SQL2008\MSSQL\DATA\northwnd.ldf' ,
SIZE = 1024KB , MAXSIZE = 2048GB , FILEGROWTH = 10%)
GO
You will need to amend the paths to a valid path for the computer on which you are running. You also will need to comment out the following lines like this:
--EXEC sys.sp_db_vardecimal_storage_format N'Northwind', N'ON'
--GO
Once you have made these changes, you can run the script in SQL Server 2005 Management Studio to recreate the database in your development environment. You can now test data against SQL Server 2008 and SQL Server 2005.
The Inevitable Limitations
Of course, this technique is not without its limitations. Here are a few to bear in mind:
The data is insecure, as it is in clear readable text. So if you are using real data, you should delete the file created once you have loaded it into SQL Server 2005. You can regenerate the file from the SQL 2008 backup, if necessary.
If you have a database with a large amount of data, the script file, of course, will be huge.
SQL Server 2008 specifics in the source database will not be migrated.
