Is it possible to fire a update trigger from SQL6.5 table to update a SQL2000 server database table field value? (upgrade this 'legacy' to sql2k now is not an option)
If it is not possible, is there a way to accomplish it?
thanks
David
We have setup a replication in SQL2000:
We have DTS package automatically pouring data into the publishing database(source tables). During this process, we want to temporary disable certain triggers. However, the command
Alter table 'tbl' disable trigger 'abc' errored out. The error message said:
''Cannot alter the table 'tbl' because it is being published for replication."
I've digged more into this and found although it's not allowed to disable a triggers,
the SQLServer do allow delete the trigger and recreate them.
Is there any way to disable the trigger directly?
Thanks in advance,
Don
BTW:
I've used the following sql directly, however the trigger still fires.
UPDATE
sysobjects
SET
status = status|2048
WHERE
type = 'TR'
AND
parent_obj = OBJECT_ID (@table_name)
The only other way around now is to create stored procedures that dynamically create the trigger. Because our trigger is normmally larger than 8000 bytes. We have to create one stored procedure per trigger. This option is not acceptable because not only it takes quite a time, but also a maintainance nightmare.
i have sql2000 & sql2005 on the same machine. I am unable to register my localhost in sql2000, get an access denied error. How can I make my localhost use sql2000 database?

i am in the process of Migrating SQL 2000 to my new SQL2000 server i want to know the what would the best way for me to migrate one SQL server to another SQL server on the same network and rename the new server to the old server and bring it up for use in our ecommerce website.
Hey,
I'm new to this whole SQL Server 2005 thing as well as database design and I've read up on various ways I can integrate business constraints into my database. I'm not sure which way applies to me, but I could use a helping hand in the right direction.
A quick explanation of the various tables I'm dealing with:
WBS - the Work Breakdown Structure, for example: A - Widget 1, AA - Widget 1 Subsystem 1, and etc.
Impacts - the Risk or Opportunity impacts for the weights of a part/assembly. (See Assemblies have Impacts below)
Allocations - the review of the product in question, say Widget 1, in terms of various weight totals, including all parts. Example - September allocation, Initial Demo allocation, etc. Mostly used for weight history and trending
Parts - There are hundreds of Parts which will eventually lead to thousands. Each part has a WBS element. [Seems redundant, but parts are managed in-house, and WBS elements are cross-company and issued by the Government]
Parts have Allocations - For weight history and trending (see Allocations). Example, Nut 17 can have a September 1st allocation, a September 5th allocation, etc.
Assemblies - Parts are assemblies by themselves and can belong to multiple assemblies. Now, there can be multiple parts on a product, say, an unmanned ground vehicle (UGV), and so those parts can belong to a higher "assembly" [For example, there can be 3 Nut 17's (lower assembly) on Widget 1 Subsystem 2 (higher assembly) and 4 more on Widget 1 Subsystem 5, etc.]. What I'm concerned about is ensuring that the weight roll-ups are accurate for all of the assemblies.
Assemblies have Impacts - There is a risk and opportunity impact setup modeled into this design to allow for a risk or opportunity to be marked on a per-assembly level. That's all this table represents.
A part is allocated a weight and then assigned to an assembly. The Assemblies table holds this hierarchical information - the lower assembly and the higher one, both of which are Parts entries in the [Parts have Allocations] table.
Therefore, to ensure proper weight roll ups in the [Parts have Allocations] table on a per part-basis, I would like to check for any inserts, updates, deletes on both the [Parts have Allocations] table as well as the [Assemblies] table and then re-calculate the weight roll up for every assembly. Now, I'm not sure if this is a huge performance hog, but I do need to keep all the information as up-to-date and as accurate as possible. As such, I'm not sure which method is even correct, although it seems an AFTER DML trigger is in order (from what I've gathered thus far). Keep in mind, this trigger needs to go through and check every WBS or Part and then go through and check all of it's associated assemblies and then ensure the weights are correct by re-summing the weights listed.
If you need the design or create script (table layout), please let me know.
Thanks.

I want to be able to create a trigger so that when a row is inserted into table A by a specific user then the ID will appear in table B. Is it possible to find out the login id of the user inserting a row?
I believe the trigger should look something like this:
create trigger test_trigger
on a
for insert
as
insert into b(ID)
select i.id
from inserted i
where
--specific USER

View 3 Replies View RelatedWhen a row gets modified and it invokes a trigger, we would like to beable to update the row that was modified inside the trigger. This is(basically) how we are doing it now:CREATE TRIGGER trTBL ON TBLFOR UPDATE, INSERT, DELETEasupdate TBLset fld = 'value'from inserted, TBLwhere inserted.id= TBL.id....This work fine but it seems like it could be optimized. Clearly we arehaving to scan the entire table again to update the row. But shouldn'tthe trigger already know which row invoked it. Do we have to scan thetable again for this row or is their some syntax that allows us toupdate the row that invoked the trigger. If not, why. It seems likethis would be a fairly common task. Thanks.

View 4 Replies View RelatedHi,
I am not sure if this is the right forum to post this question.
I run an update statement like "Update mytable set status='S' " on the SQL 2005 management Studio.
When I run "select * from mytable" for a few seconds all status = "S". After a few seconds all status turn to "H".
This is a behaviour when you have an update trigger for the table. But I don't see any triggers under this table.
What else would cause the database automatically change my update?
Could there be any other place I should look for an update trigger on this table?
Thanks,
Hi all in .net I've created an application that allows creation of triggers, i also want to allow the deletion of triggers.
The trigger name is kept in a table, and apon deleting the record i want to use the field name to delete the trigger
I have the following Trigger
the error is at
DROP TRIGGER @DeleteTrigger
I'm guessing it dosen't like the trigger name being a variable instead of a static name
how do i get around this?
thanks in advance

Hi,I have made a web application using SQL Server 2005
Express with a few admin pages that require login. I used the SQL
Server Managment Studio Express to setup users and groups and it works
fine. But the web server has SQL Server 2000 and all I get is a
user id and password to access the database. It seems I cannot use the
Login control I put on my "login.aspx" page becuase it uses the
integrated authentication which chokes on 2000. I am afraid I wonlt be
able to use some of the 2.0 features such as profiles, ... Is
this the way 2.0 works with SQL Server 2000? Should I ditch the ISP if
they only give me a single access to database with no provisions to
create users. (I was told I had to create a "Users" table and manually
assign ids and passwords and that I can only use the user id and
password they supplied to setup the connection string in the script.)I appreciate your help.
Does anyone know when SP1 will be available for SQL2000??
Thanks,
Steve Bajada

Hi,
I have a trigger set on TABLE1 so that any update to this column should set off trigger to write to the AUDIT log table, it works fine otherwise but not the very first time when table1 has null in the column. if i comment out
and i.req_fname <> d.req_fname from the where clause then it works fine the first time too. Seems like null value of the column is messing things up
Any thoughts?
Here is my t-sql
Insert into dbo.AUDIT (audit_req, audit_new_value, audit_field, audit_user)
select i.req_guid, i.req_fname, 'req_fname', IsNull(i.req_last_update_user,@default_user) as username from inserted i, deleted d
where i.req_guid = d.req_guid
and i.req_fname <> d.req_fname

I am developing a Crystal Reports App in VS2005 (VB). I was originally working on an XP machine with MSDE and stored procedures where it worked fine.
I then transferred the development to a Win2003 machine with SQL2000 and am now getting the following error;
Failed to open a rowset. Description: 'Get_Calls_By_MLO_Date' expects parameter '@DT1' which was not supplied. Plus some other error detail.
Here is the SP.
CREATE PROCEDURE Get_Calls_By_MLO_By_Date @DT1 datetime, @DT2 datetimeASSELECT MLO, CallNo, DT, Type FROM ActionsWHERE dt >= @DT1 AND dt <= @DT2 AND ActionID=1 ORDER BY MLO, DTGO

Any ideas?

Hi all,
We're beginning to migrate our 6.5 DB's to SQL2000. A question came up regarding naming conventions for stored procedures. In BOL it says that for SQL2000:
"Stored procedures with the prefix sp_ are first looked up in master. If a user-defined stored procedure has the same name as a system-supplied stored procedure residing in master, SQL Server always finds the system-supplied stored procedure. "
Behavior in 6.5 was the opposite: SQL Server searched the current database followed by a search in master.
We started several months ago renaming user stored procedures to "usp_XXX", but we still have many non-system sp's that still use "sp_". I'm looking for opinions of whether we should bite the bullet now and rename all our non-system sp's at this time; prior to moving our production environment to SQL2000. Will we see a performance gain since SQL will not have to hit master first before going to the current DB?
Any and all opinions welcome!
Thanks,
Tom Rosebrook

When bcp'ing in data into an sql 6.5 table that is NOT nullable, records in the text file that contain nulls are ommited, but valid records without nulls are inserted.
However, using exactly the same table structure and files on a newly installed sql 2000 server (sp2), as soon as the first invalid record in the text file (i.e. with a null value)is encountered, bcp'ing is terminated and NO records are inserted.
I can't find any option in bcp/sql 2000 to allow me to carry out a load as before.
The help files state that the default no. of invalid records allowed is 10 (both versions sql), and explicitly setting the -m option of bcp to 10 still doesn't work.
Most of the data i receive has at least one duff record
Is there an option in sql 2000 that allows me to have x number of duff records inserted before a full rollsback occurs?
I can't find anything in technet, msdn or books online.
In a replication environment:
Does SQL 2000 standard edition support replication if it would be configured as a subscriber.
Is SQL 2000 Enterprise Edition required for a Publisher and Distributor or can you get away with standard edition.

I need some strong points for the management to convince them to upgrade to sql2000 now than waiting for 6 months.
We are currently in process of developing this new product. All development is on sql7. I want to upgrade our database to sql2000 now rather than waiting after the release which might be in another 3 months.

I noticed that when I installed SQL2000,with "typical install",
the default, the following will be used:
SQL collation (dictionary order, case-insensitive, assent sensitive)
sp_helpsort will give
SQL_Latin1_General_CP1_CI_AI
Is there any difference if I choose the "custom install", then and choose
the windows locale which gives the result of sp_helpsort:
Latin1_General_CI_AI
SQL_Latin1_General_CP1_CI_AI is supposed for backward compatibilty, so are
they actually equivalent ??
Any impact or difference we have to be aware of ??

I will be upgrading my SQL7 Servers (SP1) to SQL2000 and NT4 to WIN2000 this year. Unfortunately, I will not be able to get new boxes to do this, so I will have to do the upgrades on the systems I have. Our network people have not yet developed a plan for the WIN2K upgrade of our entire network. I will have to upgrade the SQL Servers before they have their plan together. If I want, I can upgrade the SQL Servers to WIN2K before the rest of the network. Assuming that the WIN2K upgrade and the SQL Server upgrade can not be done at the same time, which would be the better order (and why), upgrading to WIN2K and staying at SQL7 first or upgrading to SQL2000 and staying at NT4? The primary goal is to get the indexed views to improve performance on reports and queries.
Thanks for your input.
