Previously i have used sql authentication for my application but due to some reasons sql server 2000 was reinstalled with mixed mode(both windows and sql authentication). when i run my application "Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection." error message is showing
pls help me out

Does the login exist for the user? Logins are held in the master database while the users are held in each individual database. The application will fail if the login does not exist.

Mixed mode is the correct option if you want to use SQL Authentication. You cannot turn off Windows authentication. It's most likely that the server was reinstalled with Mixed Mode disabled, i.e. Windows Authentication only.
You will need the administrator to re-enable Mixed Mode. In Enterprise Manager, connect to the server, then right-click the server in the tree and select Properties. On the Security tab, ensure that Authentication is set to "SQL Server and Windows" rather than "Windows only". Click OK, then you will have to restart SQL Server.

You need to associate a certain user to the database you want to access.
Using Object Explorer, Go to Security -> Login, Right click Login then select New Login, create your user account. Then on the left side, select User Mapping then put a check on the database you want to access with this user account, check everything below except the denyreader and denywriter (It's up to your preference).

I had detached my MSSQL 2005 DB and attached the DB without log file because it is getting too big. After attaching the log, the log seem to be NOT growing anymore. What has happen to my log file? Is there anyway or software that can view the log file?
|

If you attached the database without the log file, SQL Server may have created a new log file, depending on the options you selected. It may well not be in the location you expect. In SQL Server Management Studio, right-click the database and click Properties. Under Files, scroll to see the Path and File Name columns. This will show where the log file is and the name of the file.
The transaction log is used to record all operations that are performed in the database. This is done using slow, reliable I/O in such a way that the log can be used to undo the operations should a power outage or other failure occur, or if a transaction is aborted. In practice the log is also used to defer writing back changes to the database itself - after the log data is written to disk, SQL Server only updates the affected areas in memory, lazy-writing these. It does ensure that the writes to the database file are done in a fairly timely fashion - it tries to ensure that recovery after a failure will take a bounded time, which is configurable (the 'recovery interval' option, which is set per-server, and defaults to 'automatic' which currently means about one minute). When performing a recovery operation, SQL Server may need to actually reperform actions that made it into the log but weren't yet written to the data files.
What happens to log records that represent changes that have been committed, and securely written to disk, depends on whether SQL Server thinks you want to retain the log records. If not, these log records then become available for reuse. When the end of the log file is reached, if the area at the beginning is available for reuse SQL Server will wrap around, otherwise it has to grow.
Whether SQL Server retains the log records depends on the recovery model and whether you've backed up. If the recovery model is set to Simple, SQL Server does not retain the logs. If, however, it is set to Full or Bulk Logged, and you have made at least one full database backup, it assumes that you do want to keep a backup chain and does retain the logs.
Why would you want to do this? Because if you have the log file and log backups available, you can restore not just the last full backup but also roll forward to the point of failure, or to a given point in time. If you are using Full recovery model, you should ensure that you're regularly backing up the transaction logs as well as the database - a full backup does not clear the transaction log chain (unlike Exchange, for example).
If you are using Full or Bulk Logged recovery model but want to reset your log chain, you can issue the command
BACKUP LOG database WITH TRUNCATE_ONLY which marks all committed transaction log records as reusable. It will then not keep a log chain until you next do a full backup. To actually shrink the log file you will need to then use the Shrink Database feature.
There are tools available that can view the log file but they're not cheap.

I am developing an application and i have used the Dataset technology to retrieve data from the Database(SQL server 2000).
The problem is that on loading some Forms that retrieve the data from the Database Via the dataset it takes too much time what could be the problem

Actually it is depend on the your page server controls.
if you use Gridview than it is take time for loading.

There are a million and one things that could be the problem. But without a better description from you it makes it hard to us to diagnose.
Some things to look at:
How long does the query take to run in SQL Server itself?
How much data is being transferred? What are you doing to it before the user gets to see it?
Do you need a DataSet? Would a forward-only read-only view be more efficient?

You can use Threads so the form will not lock up.

create proc sp_temp @columnname varchar(25),@value varchar(25) as
declare @sql nvarchar(400)
set @sql='select *from tblname where '+@columnname+' = '+@value
exec(@sql)
This is the code. This procedures works for integer value when I insert in @value but for a string value; it gives invalid column name. Can anyone help me out

Just check your table detail. It will be because of you have defined the column name as int while creating the table.
|
|
|
|
|
ok, Now i got your problem and your solution is given here.
set @sql='select *from tblname where '+@columnname+' = '+''''+@value+''''
I have tried it and its working.
|

|

Print your SQL query before executing, you will get the problem.
|
|
|
|
|
Try This it's help u
set @sql='select * from jc_student_master where '+@columnname+' = '''+@value+''' '
|
|
|
|
|
If you are using EXEC command to execute a sql String then the parameter has to converted into Character and made as a part of the query before execution.
try this...
set @sql = 'select * from tblname where ' +
@columnname + ' = ' + CAST(@value AS NVARCHAR(50))
EXEC(@sql)
