How To Capture The Correct Identity Value
Sep 15, 2006
I have a stored procedure which will do 2 insert statements on 2 different tables. In my 2nd insert statement, I need to know how to capture the exact identity primary key value of the newly inserted record from the first insert statement. I am not sure how to get the correct key value of the new record because there may be more than one user inserting at the same time. Therefore, it is tough to capture the key value that belongs to the user doing his transaction at the time. Please help out. Thanks in advance.

We are running MS SQL Server 7.0
Target table has single trigger to maintain update time stamp.
We have many copies of the same database schema running on one server, all with unique database names. Such as Test_DB, Development_DB, etc.
This problem only occurs in one database, that was created using a 'restore' of another database.
Problem only happens in a single stored procedure.
Problem:
delete all rows from table (empty table)
Runn dbcc checkident ( 'T_BATCHES', reseed, 0)
Run procedure which does the following:
- Begin transaction
- Insert row into table
- Look at identity value (@@identity) - its value is 2 (*** THIS IS WRONG **)
- Select identity column from table - its value is 1
- Commit transation
The @@identity value being reported is one greater than the actual value in the database.
This does not occur if I do the same steps outside of the stored procedure.
Also, this same code and DDL run in other databases.
Help!
Thanks.

After SQL server service restart, a column which is set to auto increment jumped 1000. To fix the issue, I had to add T272 trace flag to SQL startup parameters. However, I did not see the column being reseeded after the service restart, it is still showing the 1000 jump. Am I doing something wrong?
Below the log showing the flag being added to the error log:
LogDateProcessorInfoErrorMSG
2015-06-15 22:29:53.850ServerRegistry startup parameters:
-d E:DATAmaster.mdf
-e E:logERRORLOG
-l E:DATAmastlog.ldf

I need help. The security principal is the correct DomainUser, but the error message says I am not authenticated.
So here is my error Message:
Login failed for user 'NT AUTHORITYANONYMOUS LOGON'. Me.User.Identity.Name=CompanyDomainRyan; System.Security.Principal.WindowsIdentity.GetCurrent=CompanyDomainRyan; HttpContext.Current.User.Identity.Name=CompanyRyan
Generated by:

Me.lblError.Text = ex.Message & vbCrLf & vbCrLf & "Me.User.Identity.Name=" & Me.User.Identity.Name & "; System.Security.Principal.WindowsIdentity.GetCurrent=" & secPrinc.Name & "; HttpContext.Current.User.Identity.Name=" & HttpContext.Current.User.Identity.Name
Here is the Connection String:
Private ConnString As String = "Server=10.144.162.111;Database=DNS;Trusted_Connection=True"
IIS has 4 websites hosted on it. The parent level allows anonymous with windows auth off, but the website level has anonymous off with widnows auth and digest.
In IIS, is there a problem with having the parent level anonymous and website level windows auth?

While I have learned a lot from this thread I am still basically confused about the issues involved.
.I wanted to INSERT a record in a parent table, get the Identity back and use it in a child table. Seems simple.
To my knowledge, mine would be the only process running that would update these tables. I was told that there is no guarantee, because the OLEDB provider could write the second destination row before the first, that the proper parent-child relationship would be generated as expected. It was recommended that I create my own variable in memory to hold the Identity value and use that in my SSIS package.
1. A simple example SSIS .dts example illustrating the approach of using a variable for identity would be helpful.
2. Suppose I actually had two processes updating these tables, running at the same time. Then it seems the "variable" method will also have its problems. Is there a final solution other than locking the tables involved prior to updating them or doing something crazy like using a GUID for the primary key!
3. We have done the type of parent-child inserts I originally described from t-sql for years without any apparent problems. (Maybe we were just lucky.) Is the entire issue simply a t-sql one or does SSIS add a layer of complexity beyond t-sql that needs to be addressed?
TIA,

I want to insert a new record into a table with an Identity field and return the new Identify field value back to the data stream (for later insertion as a foreign key in another table).
What is the most direct way to do this in SSIS?
TIA,
barkingdog
P.S. Or should I pass the identity value back in a variable and not make it part of the data stream?

I have table of three column first column is an ID column. However at creation of the table i have not set this column to auto increment. Then i have copied 50 rows in another table to this table then set the ID column values to zero.
Now I have changed the ID column to auto increment seed=1 increment=1 but the problem is i couldn't figure out how to update this ID column with zero value set to each row with this auto increment values so the ID column would have values from 1-50. Is there a away to do this?

Is there a way to capture every change made in a database? I would like to be able to audit and report on all changes made in our corp. database. Is there a system tool or function that can accomodate such a thing? Transaction Log maybe??

I'm working with a third-party database (SQL Server 2005) and the problem here is the following:
- There are a bunch of ETL processes that needs to insert rows on a table (let's call this table T) and at the same time, an ERP (owner of T) is up and running (reading, updating and inserting on T).
- The PK of T is an Integer.
Today all ETL processes uses (select max(ID) + 1 from T) to insert new rows, so just picture the scenario. It is a mess! Everyday they get duplicate key error when 2 or more concurrent processes are trying to insert a row (with the max) at the same time.
Considering that I can't change the PK, what is the best approach to solve this problem?
To sum up:
* I need to have processes in parallel inserting on T
* I can't change anything on T
* The PK is NOT an Identity

Hi,
We would like to capture events in our system. There seem to be
three obvious capture points for us - application, triggers, transaction
log. The latter seems to be the most attractive, since we`re looking
for a solution with minimal performance impact. In general, our
problem is similar to populating data warehouses from on-line databases.
Can anyone proffer some advice? In particular, being quite new to
SQL Server, I am not sure how difficult/possible it is to read the
transaction log in order to cull events. Some direction here would
be greatly appreciated.
Thanks,
Karl

Hi all,
Is there anyway to capture the SQL Server Error and act accordingly?
I donot want sql server to raise an error when a Primary key violation has occured. Instead i want to capture that error(number,description etc) and act
accordingly.
Whats happening is, from the application we are trapping this sql error
and raising it. Instead, if somebody inserts a record which already exists, then we want to trap that error from the sqlprocedure itself and then do an update to that record.
thanks for the help

Hi All.
I have this project that I need help with. There are 9 tables that I need to capture everything that happens to them (update, insert, delete). I was thinking of creating triggers. If someone does any of these actions against them then I need to insert into another table the date, the table name, the command that was run, and the records that are affected by it. Now I know how to do the date and table name, that's easy. My question is how do I capture the command. Once I have the command I can get the records affected.
If anyone knows how to do this, please help.
Thanks,
ODaniels

contacts.AddtblContactsRow(contact); int rowsAffected = Adapter.Update(contact);
return rowsAffected == 1; }
The primary key in this table is a BigInt set as an identity column....How do I capture the value of the primary key that gets created when the new row is added?

Does anybody know of a way to set up a task which will send an email with an attachment other than using sp_sendmail. Sp_SendMail will run a query and send the results as a text file. But I need to run a stored procedure which generates an Excel spreadsheet then have an email sent with the Excel file as an attachment. The sp_sendmail text file just doesn't work with the information I am generating so I need to find another solution.
Thanks for any help.

Using SQL Server 2000
I have to leave a production trace running for a couple of days to track down a little bit of data corruption. I am setting the stop time and maximum file size and I am running it from another machine and writing to a file and not a table and all of that good stuff.
however since I am going to be leaving this running for a while I do not want to deal with a gigantic file to sift through I am trying to limit my trace to all of the stored procs, which can be coming from other databases, to those inserting and and updating a particular table.
I have been goofing around with the Objects:Closed and Objects:Open and the SP:Starting And SP:Completed events, but I can not seem to make this work. I skimmed through the first 5 pages of my google search and my BOL search, but came up empty.
Is this possible? I thought I had done this before.

One of my co-worker told me I can do this to capture errors and insert into error table but when I test it, it doesn't work. Here is what I try to accomplish. SQL 2012. In reality, I have more complicate queries than below.
1. Insert data FROM SourceEmployee INTO Employee table and capture emp_id and error msg insert into dbo.##temperror table
2. Continue on the process until no more record. Basically, skip the error records and do a while loop until end of record.
--DROP TABLE dbo.Employee;
CREATE TABLE [dbo].[Employee]
(
[emp_id] [int] NOT NULL,
[last_name] [varchar](20) NULL,
[first_name] [varchar](15) NOT NULL,

Happy New Year everyone!I would like to capture CPU Utilization % using TSQL. I know this canbe done using PerfMon but I would like to run TSQL command (maybe onceevery 5 minutes) and see what is the CPU Utilization at that instant sothat I can insert the value in a table and run reports based on thedata.I have spent a good amount of time scouring google groups but this isall I have found:SELECT(CAST(@@CPU_BUSY AS float)* @@TIMETICKS/ 10000.00/ CAST(DATEDIFF (s, SP2.Login_Time, GETDATE()) AS float)) ASCPUBusyPctFROMmaster..SysProcesses AS SP2WHERESP2.Cmd = 'LAZY WRITER'Problem is this gives me total amount of time CPU in %) has been busysince the server last started. What I want is the % for the instant -the same number we see in Task Manager and PerfMon.Any help would be appreciated.Thanks
