It happened accidently that we deleted records from a table in SQL server 2005 DB. We never took a full backup of the DB till then. Is there any way that we can recover the deleted records. Logs files are still present. ( *mdf and *ldf ).

A mistake was made and "old" transaction logs (and old backups) weredeleted. It appears that a long living transaction was living in one ofthose logs. Now the EP shows (no items). The DBs themselves are stillfunctioning OK, just the EP shell that's not working.What's the proper resolution?Thank you in advance,FBCK

View 7 Replies View RelatedGreetings,
I got severe data corruption issue today when I copied a SQLServer2000 database from our remote server to my local PC through enterprise manager. The new copy on my local PC did not have any records in the user tables, and when I looked at the remote server, the records gone either with only table skeletons and procedures there. The mdf file on the remote server is emptied at all, but that on my local PC still has 50MB. I think there are data in this file, but the ldf log was also emptied, but I cannot recover it -- I do not have backup and the ldf file was also emptied.
I ran checkdb, and it did not tell any error but show that all the user defines tables has zero records.
I wonder whether there is now any way to recover the data. They are important and I really dont want to lose them.
Thanks in advance!
Hi,
The standby file (.tuf file) got deleted accidentally on the secondary. How can I recover the database without the standby file?
SQL 7 SP2
Are the tables inserted and deleted available from within a sp which is called from a trigger ?

I was wondering if there is a way to schedule the deletion of temporary tables that are over a certain age. Right now, temporary tables are being created, but unless I delete them manually, they end up building up and just taking up a lot of space.
View 5 Replies View RelatedI am reading the WROX "Professional SQL Server 7 Programming" book.
The following code appears on page 424:
CREATE TRIGGER ProductIsRationed
ON Products
FOR UPDATE
AS
IF EXISTS
(
SELECT 'True'
FROM Inserted i
JOIN Deleted d
ON i.ProductID = d.ProductID
WHERE (d.UnitsInStock - i.UnitsInStock) > d.UnitsInStock / 2
AND d.UnitsInStock - i.UnitsInStock > 0
)
BEGIN
RAISERROR('Cannot reduce stock by more than 50%% at once.',16,1)
ROLLBACK TRAN
END
The trigger fires when an UPDATE is made to Products table. The author states that the Inserted and Deleted tables only exist for the life of the trigger, not before, and not after the trigger runs. If this is true, then why would there be any rows in the Deleted table in this case? No rows were
deleted within the trigger. As far as I can see, no rows have been updated
either. If the condition does exist, no rows will be updated, and an error will be displayed. Otherwise, the row will be updated. Then there would be a row in the inserted table. But then the trigger is finished and the inserted table for that trigger disappears. I think my logic is flawed, which is why I am writing. I don't think I fully understand the Inserted and Deleted tables.
Any help would be greatly appreciated.

I want to know how inserted and deleted temp tables in SQL server work. My question is more regarding how they work when multiple users accessing the same database. Suppose two users update the database at the same time. In that case what are the values stored in the inserted and deleted tables.
I have a trigger that records changes to the database as in an audit trail. Like any other audit trail I insert data into my audit table from the inserted and deleted temp tables in MS SQL Server. I however am not clear as to how these inserted and deleted tables store values when two users update the database at the same time. Are there separate inserted and deleted tables for each session. The users access the database thru ASP pages.
The audit trail I am trying to use is http://www.nigelrivett.net/AuditTrailTrigger.html
I actually would like to store the inserted and deleted temp tables into other temporary tables so that I can access these tables thru a stored procedure. This is when the problem of same users updating the temporary tables is more pronounced.
Thanks in advance.
Hi all,
I just ran across an issue on a SQL 2000 sp4 db where RI was being maintained solely with triggers. I am attempting to change the primary key of a parent table and cascade the results to all its children without using the vendor-supplied trigger code (long story...) using an INSTEAD OF trigger.
My question is: does SQL Server create any kind of relationship between the inserted and deleted tables that I could exploit since the key field is unavailable?
I am trying to avoid having to add a surrogate key to each of the children just for this activity (as there are many M rows in each and no other suitable unique column combinations that span all the child tables).

I'm know the above tables are system generated, am I right in assuming the following.
1) The tables are unique to the current user.
2) The tables only last as long as the transaction that caused their creation
Thanks in advance

Hi, eveyone..
I have a problem.
One of developer deleted Merge Replication Job.
However there is no doc for that replication.
What I want to know is like this:
which tables are in that replication?
Is there any system or user tables track down these replication as well as configuration in that replication?
Thanks in advance:-))

Hello,
I have a stored procedure that's running a little slower than I would like. I've executed the stored proc in QA and looked at the execution plan and it looks like the problem is in a trigger on one of the updated tables. The update on this table is affecting one row (I've specified the entire unique primary key, so I know this to be the case). Within my trigger there is some code to save an audit trail of the data. One of these statements does an update of the history table based on the inserted and deleted tables. For some reason this is taking 11.89% of the batch cost (MUCH more than any other statement) and within this statement 50% of the cost is for a table scan on inserted and 50% is for a table scan on deleted. These pseudo-tables should only contain one record each though.
Any ideas why this would be causing such a problem? I've included a simplified version of the update below. The "or" statements actually continue for all columns in the table. The same trigger template is used for all tables in the database and none of the others seem to exhibit this behavior as far as I can tell.
Thanks for any help!

UPDATE H_MyTable
SET HIST_END_DT = @tran_date
FROM H_MyTable his
INNER JOIN deleted del ON (his.PrimaryKey1 = del.PrimaryKey1) and
(his.PrimaryKey2 = del.PrimaryKey2)
INNER JOIN inserted ins ON (his.PrimaryKey1 = ins.PrimaryKey1) and
(his.PrimaryKey2 = ins.PrimaryKey2)
WHERE (his.HIST_END_DT is null)
and ((IsNull(del.PrimaryKey1, -918273645) <>
IsNull(ins.PrimaryKey1, -918273645)) or
(IsNull(del.PrimaryKey2, -918273645) <>
IsNull(ins.PrimaryKey2, -918273645)) or

I want to compare the before and after values of an UPDATEd column using a trigger. I want to know if the value in the column has changed. Simple? No!
As you know, SqlServer puts the before image of the UPDATEd rows into the DELETED virtual table and the after image of the UPDATEd rows in the INSERTED virtual table.
So you would get the before and after data by doing a SELECT on these tables.
But here is the problem - how do you join the tables? What if there are >1 rows in these 2 tables (because the UPDATE affected >1 rows) - how do i know which "old"/DELETED rows correspond to which "new"/INSERTED?"
Ok - I could join the 2 tables on the primary key, but what if the primary key was updated? In that case the join would not work - the DELETED table would contain the old primary key value and the INSERTED table would contain the new (different) primary key value. In fact, ALL of the columns may have been changed by the UPDATE.
Now, there is another thing to try with triggers - the
IF UPDATE ( <columname> )
test. This is designed to tell you if a specified column was UPDATEd by the last UPDATE. However, this will return TRUE for any UPDATE that mentions the column - even if the UPDATE does not change any data! So I cannot determine whether a certain column has had its value changed with this either.
So then you can try another test mentioned in the docs for CREATE TRIGGER - the
IF COLUMNS_UPDATED()
test. However, this will report that a column has been updated, NOT whether the data has changed as aresult of that UPDATE.
So if you UPDATE the value in the column to the same value as it was beforehand (admittedly, a pointless thing to do, but it could happen in some apps), this fuction will say, yes, this column was updated.
So my question remains - how do I know if the data has changed in a column after an UPDATE, using a trigger?
Any ideas?
I dont know what I am doing wrong. The trigger (see below) is doing what I want it to do when I do this:
INSERT INTO dbo.personal
(personal_id, chef_id,fornamn, efternamn)
VALUES
(40, 100, 'Malin', 'Markusson' , 'Boss')
but when I remove one value, the result in the logtable is NULL:
INSERT INTO dbo.personal
(personal_id, chef_id,fornamn, efternamn)
VALUES
(40, 100, 'Malin', 'Markusson' )
How can I change the trigger so that it will give me the information of the values that have been updated, inserted or deleted when I dontchange all values (just a couple of them)?
My trigger:
CREATE Trigger trigex
ON dbo.personal
FOR insert, update,delete
AS
INSERT INTO logtable (Innan_värde, Ny_värde)
SELECT
rtrim(cast(d.personal_id as varchar)+', '+cast(d.chef_id as varchar)+', '+rtrim(d.efternamn)+', '+ rtrim(d.fornamn)+ ', '+ rtrim(d.titel)),
(cast(i.personal_id as varchar)+', '+cast(i.chef_id as varchar)+', '+rtrim(i.efternamn)+', '+ rtrim(i.fornamn)+ ' '+ rtrim(i.titel))
FROM inserted i full join deleted d on i.personal_id = d.personal_id
My table:
CREATE Table logtable
(Innan_värde varbinary(max),
Ny_värde varbinary(max))
Thank you !
can anybody tell me with an example how to use Inserted and Deleted in Sql Server 2005
View 7 Replies View RelatedPlease i have a question,
I want to use temporary tables to handle my forms child tables data.
My question is after i load the data from #temporary table to my dataset then i will close my database connection.
Does my temporary tables gets dropped off as soon as i do the connection.close.
or do i need to drop the #temporary table by code.
Which one is right.
I know #temporary tables are specific to the users(session)
Thank you very much in advance.
We have an app that uses triggers for auditing. Is there a way to know the order that the records were inserted or deleted? Or maybe a clearer question is.... Can the trigger figure out if it was invoked for a transaction that "inserted and then deleted" a record versus "deleted and then inserted" a record? The order of these is important to our auding.
Thanks!

I have a table that sometimes has modifications to column(s) comprising the primary key [usually "end_date"]. I need to audit changes on this table, and naturally, turned to after triggers.
The problem is that for updates, when the primary key composition changes, I'm not able to relate/join using the primary key - obviously, it no longer matches across INSERTED and DELETED. Now, for a single row update, it's easy to check for updates on PK columns and then deduce what changes were made...
So the real question is: are rows in INSERTED and DELETED always in matching order (1st row in INSERTED corresponds to the 1st row in DELETED...)?
I don't want to put a surrogate key (GUID nor IDENTITY) on the base table if at all possible. INSERT... SELECT from the inserted/deleted tables into a temp table with identity column is fine, and is what I'm currently doing; I would like MVP or product engineer level confirmation that my ordering assumption is correct.
Testing using an identity surrogate key on base table, and selecting from the Ins/del tables, and the temp tables without an order by clause seems to always return in proper order (proper for my purposes). I've tested under SQL 2005 RTM, SP1, SP2, and SP2 "3152".
FYI, I've lost the debate that such auditing is better handled by the application, not the database server...
Aside: why doesn't the ROW_NUMBER() function allow an empty OVER( ORDER BY() ) clause? Will SQL ever expose an internal row_id, at least in the pseudo tables, so we can work around this situation?
Thanks
Mike
