SQL2k Profiler - Tracking Inserts And Deletes
Nov 16, 2006
SQL 2K - SP3a - Development Box
The environment is a piece of garbage ... triggers firing triggers firing triggers. Application is a piece of garbage that a developer want to make better (yea!) I need to put together a profile template to capture inserts and deletes into two tables.
Not asking for the fish (but will accept it if necessary). Looking thru BOL, cannot find find an event class to capture insert and / or delete. Looking at TSQL event class gives SQLStmtCompleted event, and maybe I can filter on the two object IDs (object name not available because dbname not available as data column for this event.) Or if exists, but not documented, the event class for insert and delete.
Any ideas?

I need to create a table that only allows records to be inserted or deleted. Once the record has been created it can only be deleted. Is there anyway to configure a table in this manner?
Table Definition

GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].[TBL_PCL_LENS_DATA](

I have transactional replication set up between two SQL Server 2000 databases. In some cases when I perform an UPDATE on a published table on the the publisher, SQL Server attempts to perform a DELETE followed by an INSERT on the subscriber using the stored procedures created during the initial snapshot.
Why does it do this?
How can I stop it doing this and force an UPDATE on the publisher to call the UPDATE procedure on the subscriber?
Thanks

Ok, I think this may have a simple answer. Basically I have no problems in setting up QueryString/Control/etc parameters when I use SELECT in the Configure Data Source Wizard as it prompts me for the necessary parameters. But when I try to use the Configure Data Source Wizard with an UPDATE, INSERT or DELETE it does NOT prompt me for the required parameters.Is this a bug or am I just missing something? Do I have to put them in manually or something?Thanks!

I have a 14GB database whose data content is legacy and is described as static. The log file is significantly large and continues to change size mostly increasing by 2-5GB a day (~60GB now) I have observed over the past two days; it shrank once unexpectly by a few GB. The instance is hosting other databases such as: EnterpriseVaultDirectory, EnterpriseVaultMonitoring, EnterpriseVaultStore, and NetPerfMon - might these seemingly unrelated data sources be involved?
I am trying to a trace to find traffic against the tables, no such luck.
Web applications are playing against it for queries but there should be no UPDATEs beign applied. I can only suspect that other unknown applications are performing operations but have yet to find unexplained connections.
Are there any other reasons why this type of log file activity would happen merely due to queries or stored procedure calls?
Lets also state, "mirroring, indexing, replication" are not at play. I know logging "Full" is not necessary as "Simple" should suffice but I am still hunting down why UPDATEs might be getting through. I realize I might adjust the migrated SQL 2000 security model to deny updates to find what breaks but would rather not take that iniative yet.
The installation is a fresh SQL 2005 Standard setup with SP2 applied; the databases were upgraded.

The company for which I work did not have a DBA until I started a few weeks ago. Whoever installed SQL2K used the wrong CD so they have been running Personal Edition on their servers. I have installed a new SQL2K standard instance and have restored everything except the jobs and DTS packages. Can the msdb from the Personal edition be restored to the standard instance?

Is it possible to downgrade SQL from Enterprise to Standard Edition, or do you have to remove the previous installation (uninstall) and reinstall. Meaning you would also have to restore all user databases? Thanks.

Hi,
We are developing a new oltp application using SQL Server 2000 and are debating whether to use "cascade delets" or not. In earlier apps, we had issues using cascade deletes like someone deleted parent by mistake and all child records got deleted OR SQL Server crashed in middle of cascade delete and records were lost or performance became an issue when there were huge # of child records to be deleted,etc.
Are there any recommendations for/against using Cascade deletes and when to use and when NOT to use cascade deletes ?
Thanks

I need some suggestions concerning the issue cascading deletes in a self-referencing table, i.e. a table with a foreign key pointing at the primary key in itself. Although SQL Server still does not support cascading deletes the declarative way there are some other ways to handle this situation. One common way is to use trigger coding with the simple structure
CREATE TRIGGER DelCascadeTrig
ON self_ref_tab
FOR DELETE
AS
DECLARE @C_FK xxxxxx
SELECT @C_FK = C_FK FROM DELETED
BEGIN
DELETE self_ref_tab
FROM self_ref_tab, deleted
WHERE self-_ref_tabC_FK = deleted.C_PK
END
where C_PK is the primary key column and C_FK the foreign key column. The problem is that this simple pattern does not work with self-referencing tables, because the removal of dependent rows deeper layer (n-2, n-3 etc. if the originating delete request is level n and the first level of dependant deletes handled by the trigger code is n-1) would require the delete trigger to fire more than once for the same delete operation. As far as I know, in ver. 6.x triggers are executed only once per SQL statement and in this case the n-2, n-3 etc. level rows would have been left as "orphans".
In ver. 7.0 I suppose this should work fine because of the new recursive trigger execution possibility (trigger will fire up to 32 recursive times per SQL statement), but in the meanwhile (i.e. my case util we have upgraded all our servers) the delete logic for a cascading, self-referencing relationship must be handled completely within one execution of the trigger.
My question is now: does anyone know anything about any common algorithm or trigger code example solving this problem.
Thanks in advance

When I setup a relationship in Access I can specify that Primary Key deletes cascade down to the Forgien Key. So when I delete an Order Header it cleans up all the items in the Order Details table for me automatically.
Can I get this same functionality in SQL Server 7 without having to write triggers or are triggers the only way?
thanks

I'm wondering if anyone has compared the speed of different kinds of deletes.
Assuming super large tables, I wonder, what is the speed ordering for the following operations:
* Remove a column
* Remove a row
* Remove a table
I'll experiment to see if I can get numbers comparing the speeds, but, if someone's already done the work, I'd love to know
thanks

I haven't used cascading deletes in the past but we're starting a new database and it seems like a good way to go to keep data clean. Or at least it did seem like a good way until I ran some tests. I have 3 tables.
People PeopleEmails Email
(pk)peopleid (pk)peopleid (pk)emailid
fname (pk)emailid address
lname emailtype
password
In this structure, the peopleemails table is simply an association table between the email and people table. I have setup up relationships in a diagram so that when a person is deleted, it cascades to peopleemails and removes the entry there. I also had a cascade set up hoping that when an entry was deleted from peopleemails, it would remove it from the email table but this is not happening. The relationship between email and peopleemail is primary key table email.emailid and foreign key table peopleemail.emailid. Is there a way to get this to work to remove the email address if a peopleemail entry is removed? Thanks.

Hello,
I have three tables:
CREATE TABLE TASKS
(
SEQNO INTEGER NOT NULL IDENTITY (10000,1),
NAME VARCHAR(20) DEFAULT '' NOT NULL UNIQUE,
PRIMARY KEY (SEQNO)
);
CREATE TABLE JOBS
(
SEQNO INTEGER NOT NULL IDENTITY (10000,1),
NAME VARCHAR(20) DEFAULT '' NOT NULL UNIQUE,
PRIMARY KEY (SEQNO)
);
CREATE TABLE JOBTASKS
(
SEQNO INTEGER NOT NULL IDENTITY (10000,1),
JOBID INTEGER DEFAULT 0 NOT NULL REFERENCES JOBS(SEQNO),
TASKID INTEGER DEFAULT 0 NOT NULL REFERENCES TASKS(SEQNO),
PRIMARY KEY (SEQNO)
);
When I delete a record in JOBS I would like to create a trigger that would delete the related records in JOBTASKS.
This is my attempt; but it does not work.
CREATE TRIGGER JOBS_BEFORE_DELETE
ON JOBS
FOR DELETE
AS BEGIN
DELETE FROM JOBTASKS
WHERE JOBID = (SELECT SEQNO FROM DELETED);
END;
Thanks,
Steve

I'm hoping someone has seen this before because I have no idea what could be causing it.
I have an SQL 2005 database with multiple tables and several triggers on the various tables all set to run after insert and update.
My program inserts a record into the "items" via a SP that returns the index of the newly added row. The program then inserts a row into another table that is related to items. When the row is inserted into the second table it gets an error that it cannot insert the record because of a foreign key restraint. Checking the items table shows the record that was just inserted in there is now deleted.
The items record is only deleted when I have my trigger on that table enabled. Here is the text of the trigger:
GOSET ANSI_NULLS ONGOSET QUOTED_IDENTIFIER ONGOALTER TRIGGER [dbo].[TestTrigger]ON [dbo].[items]AFTER INSERT
AS BEGIN
SET NOCOUNT ON;
INSERT INTO tblHistory(table_name, record_id, is_insert) VALUES ('items', 123, 1)
END
tblHistory's field types are (varchar(50), BigInt, bit).
As you can see there is nothing in the trigger to cause the items record to be deleted, so I have no idea what it could be? Anyone ever see this before?
Thanks in advance!

Hi
I keep data in four seperate locations, each with different data retention.
the problem is, i keep the publisher "thin" - only 24 hrs of data) the data in the relevant tables is about 250000 a day) and these deletes are blocked at the subscribers by commenting out the body of the repl proc.
this does however cause a burst in bandwith & locks the subscribers, even though no actual delete takes place.
does anyone know if you can actuaklly NOT REPLICATE delete commands for specified tables at all - so that the message of the delete wont even be SENT to the subscriber?

Hello everybody,
We have a Master table in the Db who's PK is referenced in at least 60 tables as FK.
We want to delete all the dependent records in 1 go without using multiple delete statements or any cursor or loop.
Is it possible? Please advice.
Thanks in advance.

Hello all.
Please help me shed light on the following problem:
I am deleting from 2 tables in a transaction. I experience a deadlock occasionally when deleting.
Here are the tables:
create table TABLE_1 (
ID integer not null,
TYPE_CD varchar(50) not null,
STATUS_ID integer not null,
NAME varchar(500) not null,
COMMENT varchar(500) null,
CREATED_DATE datetime not null,
CREATED_BY varchar(15) not null,
LASTMOD_DATE datetime null,
LASTMOD_BY varchar(15) null,
constraint PK_TABLE_1 primary key nonclustered (ID)
)
create table TABLE_2 (
TASK_ID integer not null,
TABLE_1_ID integer not null,
COMMENT varchar(500) null,
constraint PK_TABLE_2 primary key nonclustered (TASK_ID, TABLE_1_ID)
)
Table table_2 is an intersection table between table_1 and another lookup table (called task).
Whenever I delete from table_1 I need to delete from table_2 to maintain integrity.
The reason I do not have clustered indexes on the tables is b/c they start out empty (every day a housekeeping task deletes from them. Unfortunately I cannot change this...).
In my (web/jsp) application before I delete, I select from table_1 to get data I need to remember after the delete.
In order to avoid the "select for update problem", I use the "UPDLOCK" hint in the select like this:
select *
from table_1 WITH (UPDLOCK),
table_2 WITH (UPDLOCK)
where table_1.id = table_2.table_1_id "
and table_1.id = ?
and table_2.task_id = ?
I then issue my deletes in the following order:
delete from table_1
where task_id = ?
and table_1_id = ?
and then,
delete from table_1 where id = ?
The application sets the isolation level to READ COMMITTED.
The above 3 sql statements are executed as part of a transaction. Occasionally, when I drive the application, I get a deadlock. This happens intermittently. I have been able to reproduce the problem by attempting to delete records really fast, one after the other from the (web) front end.
When the deadlock occurs these are the locks that are held by the running processes:
Blocked SPID (10):
============
Object Lock Type Mode Status Owner Index Resource
app DB S GRANT Sess TABLE_2
app.dbo.TABLE_1 TAB IX GRANT Xact TABLE_2

app.dbo.TABLE_2 PAG IX GRANT Xact TABLE_2 1:176
I could not figure out what the problem is. Please help me with this.
Any help will be much appreciated.
Thanks in advance

Microsoft article Q142480 states "Triggers cannot be used to perform cascading updates and deletes if ForeignKey-to-PrimaryKey relationships have been extablished using SQL Server's DRI."
Does this mean that I cannot declare FK's in my scripts if I want to have triggers in the table? Do I just add a column in my table that will have a foreign key in it, but just not reference it in my script? Can someone clarify for me?
Thanks,

I was testing how the WITH CHECK OPTION works. I though that it prevents row from dissappearing from the view implementing this option but I found that I was able to DELETE all rows through the view - Why is this???
Please note that I only have the base version of sql server 2000 - No patches applied
Thanks for your help

Create table T100 (A int)
GO
Create view VT100 AS (SELECT * FROM T100 WHERE A < 2) with check option
GO
INSERT INTO T100 VALUES (1) -- Part of the view's result
INSERT INTO T100 VALUES (2)
GO
SELECT * FROM VT100 -- SHOWS 1

INSERT INTO VT100 VALUES (-2) -- Works

UPDATE VT100 SET A=5 -- Update fails because of WITH CHECK OPTION - GOOD

Hi,
I've been having problems with my tempdb filling up, and causing all databases on the server to stop functioning properly. I've been removing alot of data lately (millions of rows), and I think this is the reason why my tempdb log is going thru an unusual load.
Whats the best way to make sure the tempdb doesnt fill up causing me major problems? I had temporarily turned off backups while I was having a new HD put in. Am I right in thinking that when a DB is backed up, the tempdb log is reduced in size? Should maintaining a daily backup solution help keep things under control ?
Thanks very much for any tips!

I can switch off replication deletes be running the following:
EXEC sp_changearticle @publication = 'PUBNAME', @article = 'ARTICLE1', @property = 'del_cmd', @value = 'NONE'
I believe I can the effectively then remove the delete stored procedure from the replicated database.
And all this wroks no problem. However, when I come to add a new article, "Article2" to my publication it also snapshots and reinitialised the "Article1". How can I prevent the snapshot agent from re-initialising "Article1".
Thanks.
