You'll have to use a log reader tool from Lumigent or LogPi. Otherwise,
you need to restore from a backup. If the table is static, you may be
able to restore the database to another (test) server and use DTS to
copy the table.
Some backup/recovery tools like our LiteSpeed product offer object level
recovery.

Too late now but it's a good idea to bracket your ad-hoc DML statements
with BEGIN TRAN ... ROLLBACK TRAN until you are sure that the
modification is correct. Also a good idea to have a current backup of

Hi Robert,
You can't rollback after committing the transaction.
Besides the options posted by David and David, the might be one more
option for you: If your database is in full recovery mode, you can use
point in time recovery to restore yoour database to the point in time just
before you ran the unintended deletes. This will of course destroy ALL
modifications since that time, so it may or may not be usefull.

Recovery deleted row
Dear all,
if i delete a row in a table accidently , how can i recover that rows
in case 1: just delete it a few second before
in case 2: delete it and add several rows after deleted rowsSQL Server doesn't provided a 'undelete' method. You will have to read the
transaction log using commands like DBCC LOG, or fn_dblog. But there isn't
much official documentation available about these commands. Another
alternative is to use a tool like Lumigent Log Explorer that can recover
data from the transaction log, as long as that transaction is in the
transaction log.

Accidents can ONLY be prevented with precautions.
You can write a trigger to avoid deletion using @.@.rowcount, if you dont have
regular deletions. You can use this to specific user also.
If you find that official regular deletions are inevitable(practically true)
use triggers to add to to history tables so that you can easily retrieve the
row you want.

Recovery database
I have a database, but It's delete. I only file .LDF of database, Please, help recovery database
Thanks,Without the data file (mdf, ndf), you're pretty much stuck. It would help
if you've made backups. Alternatively, you could try using one of the many
disk recovery apps and hope for the best (OnTrack (commercial), Handy
Recovery (freeware)). Try not to store anything onto the disk that used to
contain the data files.

You cant recover a database with an LDF file. LDF file only contains the
active transactions information. All the data / objects will be kept in MDF
file.
Note:
A database can be recovered only if you have the MDF/NDF file for that
database. It is always recommended to take a backup of
database daily.

Recover delete the row from a table?
In SQL server 2000, one of co-work delete the row in a table. How can I
recover the row.
Thanks,Do you have transactional log backup and you know the time he deleted the
record, if so ,create a dump database
restore full data base to the dump
restore differential log to the dump
restore log with stopat option to the dump
and then copy the record from dump database to the real
other wise.. use a a tool called Lumigent log explorer

> Thanks,|||Hi,
You can recover the deleted rows by doing a POINT_IN_TIME recovery on to a
new database.
The POINT-IN-TIME recovery will work only if the source database's Recovery
model is set to "FULL" and you should
have a full database backup + subsequent transaction log backups.
Steps:
1. Perform a transaction log backup of the original database (If you have
not performed one)
2. RESTORE DATABASE TEST1 FROM BBA (Give the correct backup file / device
name) WITH NORECOVERY
3. Restore the subsequent transaction log files in order of backup WITH
NORECOVERY option till the final transaction log file
4. In the the final transaction log restore mention WITH RECOVERY and
STOPAT='date and time'
Thanks

If the recovery model is other that simple you could recover your data by
using an utility called Log Analyzer (google it). If you have some backup
strategy which imply log backup than do a restore process with stop at clause.

There are several possible reasons:
o The row you are trying to delete is locked by another process.
o There is a foreign-key constraint from a referencing table, and that
table is large, but the referencing column is not indexed, so
checking whether the row is deletable takes a very long time.
o A variation of the above, but the foreign-key relationship uses
cascading updates.
o The table has a DELETE trigger which takes a very long time to
execute.
To check for locking, issue an sp_who from another connection. If you see
a non-zero value in the Blk column, the process on that row is blocked by
the process in the Blk column.
To check the other, use sp_helpconstraint and sp_helptrigger to look
for constraints and triggers.
The above list is not necessarily exhaustive.

Records dont get deleted from the database!
I am using this code to delete records from a table in the database that has two fields (both are primary keys) I am not getting any error, but nothing gets deleted. Thanks for the help.
Code:
protectedvoid btnRemove_Click(object sender,EventArgs e){
Remove();
Response.Redirect("RegisteredCompanies.aspx");
}
protectedvoid Remove(){
//update database with filename
//Save Changes
connection.Open();
using (SqlTransaction trans = connection.BeginTransaction()){
try
{
SqlHelper.ExecuteNonQuery(trans,CommandType.StoredProcedure,"spRemoveCompany",newSqlParameter("@.Userid",getGdUserID(Profile.UserName)),newSqlParameter("@.BusinessID",getBusinessID());}
catch (Exception err){
// throw exception
trans.Rollback();
lblStatus.Text ="An error has occurred in the delete process. Please try again.";
}
}
Here is the stored procedure:
ALTERPROCEDURE[dbo].[spRemoveCompany]
@.Useriduniqueidentifier OUTPUT,
@.BusinessID uniqueidentifier OUTPUT
AS
DELETEFROMAssociations2WHEREUserid = @.Userid AND BusinessID = @.BusinessID
RETURN
You must commit the transaction in your code.
|||Also, why are you using OUTPUT on your parameters?
|||yes, I used output in the stored procedure. How do i commit the transaction? Thanks!
|||Got it working now!! Thanks a lot!!
