I have a cursor running that fails when a trigger gets fired. Is there any way to surpress a trigger from firing during this sp ? Should I be approaching this differently ?
Server: Msg 16934, Level 10, State 1, Procedure spKYLAB_SubmitGrading, Line 182
[Microsoft][ODBC SQL Server Driver][SQL Server]Optimistic concurrency check failed. The row was modified outside of this cursor.
Hi,
Does anyone know if there's a way to log batch updates done using SQL queries without using a trigger or a cursor?
Thanks in advance,

In MSDN file I read about static cursor
STATIC
Defines a cursor that makes a temporary copy of the data to be used by the cursor. All requests to the cursor are answered from this temporary table in
tempdb; therefore, modifications made to base tables are not reflected in the data returned by fetches made to this cursor, and this cursor does not allow modifications
It say's that modifications is not allowed in the static cursor. I have a questions regarding that
Static Cursor
declare ll cursor global static
           for select name, salary from ag
 open ll
            fetch from ll
Â
             while @@FETCH_STATUS=0
              fetch from ll
               update ag set salary=200 where 1=1
Â
  close ll
deallocate ll
In "AG" table, "SALARY" was 100 for all the entries. When I run the Cursor, it showed the salary value as "100" correctly.After the cursor was closed, I run the query select * from AG.But the result had updated to salary 200 as given in the cursor. file says modifications is not allowed in the static cursor.But I am able to update the data using static cursor.
Hello,I have a test database with table A containing 10,000 rows and a tableB containing 100,000 rows. Rows in B are "children" of rows in A -each row in A has 10 related rows in B (ie. B has a foreign key to A).Using ODBC I am executing the following loop 10,000 times, expressedbelow in pseudo-code:"select * from A order by a_pk option (fast 1)""fetch from A result set""select * from B where where fk_to_a = 'xxx' order by b_pk option(fast 1)""fetch from B result set" repeated 10 timesIn the above psueod-code 'xxx' is the primary key of the current Arow. NOTE: it is not a mistake that we are repeatedly doing the Aquery and retrieving only the first row.When the queries use fast-forward-only cursors this takes about 2.5minutes. When the queries use dynamic cursors this takes about 1 hour.Does anyone know why the dynamic cursor is killing performance?Because of the SQL Server ODBC driver it is not possible to havenested/multiple fast-forward-only cursors, hence I need to exploreother alternatives.I can only assume that a different query plan is getting constructedfor the dynamic cursor case versus the fast forward only cursor, but Ihave no way of finding out what that query plan is.All help appreciated.Kevin

I having a difficult time here trying to figure out what to do here.I need a way to scroll through a recordset and display the resultswith both forward and backward movement on a web page(PHP usingADO/COM)..I know that if I use a client side cursor all the records get shovedto the client everytime that stored procedure is executed..if thisdatabase grows big wont that be an issue?..I know that I can set up a server side cursor that will only send therecord I need to the front end but..Ive been reading around and a lot of people have been saying never touse a server side cursor because of peformance issues.So i guess im weighing network performance needs with the client sidecursor vs server performance with the server side cursor..I am reallyconfused..which one should I use?-Jim
View 1 Replies View RelatedHey,
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.

as
insert into b(ID)
select i.id

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 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
Thanks,

I hope this is the appropriate forum for this question, if not then I apologize.
I've got a SQL Server 2000 stored procedure that returns data to be used in a crystal report in Visual Studio 2005. Most of the stored procedure works well, but there is a point where I need to calculate an average number of days been a group of date pairs.
I'm not familiar with cursors, but I think that I will need to use one to achieve the result I am looking for so I came up with the code below which is a snippet from my stored procedure. In this part of the code, the sp looks at the temporary table #lmreport (which holds all of the data that is returned at the end to crystal) and for every row in the table where the terrid is 'T' (the territory is domestic), it selects all of those territories from the territory table and loops through them to determine the date averages (by calling a nested stored procedure, also included below) for each territory and then updates #lmreport with that data.
When I try to run the stored procedure, I get "The column prefix '#lmreport' does not match with a table name or alias name used in the query." on the line indicated.
Does anyone have any idea what might be wrong or if this will even work the way I need it to?
Thank you in advance.

I need to have atleast three records. But if random value starts the cursor at the end, the cursor would not wrap to the beginning.
Is there a way to wrap the cursor to begining if its status is not zero.
Are the cursors declared and opened in stored procedures are always the server cursors?

Something like that:
PROC A
Declare c Cursor For Exec B
PROC B
Select * From Clients
I am sure I am not the first one ask this.
I have got two tables, what I would like to do now is to update the second table using the values in the first table where
T1.id = T2.id, normally I have to use cursor to loop through table two to achieve this. But is it possible to do this without using cursor?
Thanks,

This is what I am trying to do:
Table 1 has numerous resume's for each person. Each resume has a unique id.
ie: Table 1
res_id fname lname userid pwd address city state etc...
100 John Doe jd ok xxxx xxxx xx xxxx
104 Sally May sm sm ccccc cc c cc ccc
643 John Doe jd ok ssss null null
1003 John Doe jd ok 123 elm Nome AK ...
5000 Tom Cat tc tc null null null
I need to insert into Table 2 only the demographic information for each person appearing in Table 1. The catch is that Table 2 doesn't have the same unique id that appears in Table 1. userid and pwd are unique to Table 2 but are numerous in Table 1.
Table 2
new_ident userid pwd address city state etc..
10 jd ok 123 elm Nome AK ....
11 Sally May sm sm ccccc cc c cc ccc
12 Tom Cat tc tc null null null
Basically I need to choose the most current "max(res_id)" occurance for John Doe above to get only one row out of his three rows. Then I need to get all the other unique rows from table 1.
I hope that is clear. I was considering a cursor. Any ideas??

I am trying to build a cursor based on a query that uses a variable and cant seem to make it work..
Here is the query:
declare ob_cursor cursor for
select name
from @dbname.dbo.sysobjects
where xtype = 'U'
How could I pass this cursor declaration the database name?
Any help would be appreciated.
Is using cursor the only way to do update in this case.
I'm updating TableA.ID with TableB.New_id where TableA.ID =
TableB.ID. TableA has 2.5 million records and TableB has 500,000
records. Doing it this way bring the system down to it's knees, and
is taking forever. Any suggestion are welcome.
declare mrn_cur cursor for
select dealer_ident, kealer_id
from dealer
for read only
declare @result int
declare @temp_ident int
declare @temp_id int
declare @temp_var int
open mrn_cur
fetch mrn_cur into @temp_ident, @temp_id
while (@@fetch_status = 0)
begin
begin transaction
update label
set dealer_id = @temp_ident
where dealer_id = @temp_id
commit tran
fetch mrn_cur into @temp_ident, @temp_id
end
close mrn_cur
deallocate mrn_cur
