Logging Batch Updates Without Using A Trigger Or A Cursor
May 5, 2008Hi,
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,

Batch Updates With SQL CLR
Jul 31, 2007Unfortunately batch updates (i.e. setting SqlDataAdapter.UpdateBatchSize to >1) are not possible with ADO.NET using a context connection. Does anyone know why it's not possible? Will it be implemented or allowed in a future version of .NET?
Here's what I'm currently doing:
I have a C# stored procedure, using a context connection, that updates all the records in a table (typically a million records) by repeatedly:
- sequentially reading a group of records (1000 at a time) into a SqlDataAdapter (using a 'select top row_number' -type statement that prevents re-querying processed records);
- performing complex processing on each record and writing the results back to the adapter (several fields of each record are updated);
- updating the table when each group has been processed.
This works, but it's not quite as fast as I'd have hoped for and is only slightly slower if using a non-context connection from an external application. I'd like to enable batch updating to increase performance (I actually get much faster performance from an external application that batch updates using a non-context connection, say 20% faster!)... but of course I can't with SQL CLR.
Any ideas on how I can improve performance of my updating?
Thanks in advance,
Graham
Batch Updates And Triggers
Nov 14, 2007Hello All
I am running a statment that updates 248 records in a table. That table has a trigger on update.
The First thing that the trigger does is to declare a number of variables and then set them using the values from the inserted and deleted temp tables.
This works fine when you are updating one row at a time but when you run a batch update it errors.
I believe this is because i am assuming that in a batch update a single row will be updated and then the trigger fired, then the next row and so on.
I now know that this is not the case. Is there a way of linking the 3 variables (see Below) so they all return information form a single row.
Declare@ApplicantId Int,
@NewStatus Int,
@OldStatus Int
Set @ApplicantId = (Select ApplicantID from Inserted)
Set @NewStatus = (Select StatusID from Inserted)
Set @OldStatus = (Select StatusID from Deleted)
Hope that makes sense
Thanks for any help.

How To Switch Off Transaction Logging For Inserts/updates?

View 1 Replies View RelatedFiring A Trigger When A User Updates Data But Not When A Stored Procedure Updates Data
Dec 19, 2007I have a project that consists of a SQL db with an Access front end as the user interface. Here is the structure of the table on which this question is based:
Code Block
create table #IncomeAndExpenseData (
recordID nvarchar(5)NOT NULL,
itemID int NOT NULL,
itemvalue decimal(18, 2) NULL,
monthitemvalue decimal(18, 2) NULL
)
The itemvalue field is where the user enters his/her numbers via Access. There is an IncomeAndExpenseCodes table as well which holds item information, including the itemID and entry unit of measure. Some itemIDs have an entry unit of measure of $/mo, while others are entered in terms of $/yr, others in %/yr.
For itemvalues of itemIDs with entry units of measure that are not $/mo a stored procedure performs calculations which converts them into numbers that has a unit of measure of $/mo and updates IncomeAndExpenseData putting these numbers in the monthitemvalue field. This stored procedure is written to only calculate values for monthitemvalue fields which are null in order to avoid recalculating every single row in the table.
If the user edits the itemvalue field there is a trigger on IncomeAndExpenseData which sets the monthitemvalue to null so the stored procedure recalculates the monthitemvalue for the changed rows. However, it appears this trigger is also setting monthitemvalue to null after the stored procedure updates the IncomeAndExpenseData table with the recalculated monthitemvalues, thus wiping out the answers.
How do I write a trigger that sets the monthitemvalue to null only when the user edits the itemvalue field, not when the stored procedure puts the recalculated monthitemvalue into the IncomeAndExpenseData table?
Partial Updates By Cursor
Sep 18, 1998I am are running SQLSERVER SP4 on WINNT SP3.
I am serious problem of partial update my query is
something like
bEGIN tRAN
declare cursor...
SElect * from tableA where flag = null
open cursor
fetch first...
while @@FETCH_STATUS = 0
BEGIN
UPDATE TABLE tableB ..
.
.
.
fetch next
END
CLOSE ...
DEALLOCATE..
COMMIT TRAN
The problem is the cursor select retrieves
says about 10000 rows, goes thru the
loop for 1000 rows and just terminates without
giving an error message,or rolling back
in case of errors, but comes out as successfully
completed.
I am at loss as what could be the problems..
any suggestions welcome..
Thanks in advance,
Balajee.
Trigger And Any Number Of Updates
Jan 12, 2004I've a system of users and let's call em subusers. Every User becomes an automatic generated login when entered into the database. Every subuser has a reference to his user and no login, cause only thr root in the chain is able to login. But when the user gets deleted, all subusers become a new user. I've done this with a trigger changing the superUser Value=0:
create trigger abc on Users AFTER DELETE
as
declare @h int
SELECT @h = id FOM inserted
UPDATE Users SET superUser=0 WHERE superUser=@h
Furthermore the trigger deletes all additionally data of the user.
Since every subuser of the deleted user becomes a user himself for every subuser a new Login must be created. I'm using an update triger for this task:
1: create trigger userUpdate on Users After Update
2: AS
3: DECLARE @superold int
4: @supernew int
5: @name nvarchar(55)
6: @date smalldatetime
7: if UPDATE(superUser)
8: begin
9: SELECT @superold= superUser FROM deleted
10: SELECT @supernew=superUser FROM inserted
11:
12: if @superold <> @supernew
13: begin
14: if @superold = 0
15: begin
16: DELETE FROM UserLogin WHERE id=@superold
17: end
18: else if @supernew=0
19: begin
20: SELECT @name=Name,@date=Date from inserted
21: execute createLogin @supernew,@name,@date
21: end
22: end
23: end
The problem is in line 20 and 21, cause the values @name and @date containing only the last updated user(the last entry in the inserted table) thus only for the last user a new Login is created whereas the others become the state user but no login was created. What i need is a method to loop over all entrys in the tables inserted btw. deleted.
Does anybody know how to achieve this, looping the tables and executing a stored procedure for every entry?

Instead Of Trigger And In-Place Updates
Sep 18, 2007
Converting an existing application, I have a table:
create table problem
(
building char(3),
function char(4),
sqft int,
pct dec(5,2)
)
[pct] is a problem because it depends on it's own row and the sum of all other rows for the same building:
pct = sqft / sum(sqft) over building
I want to create a trigger to update the pct column in the database instead of any business layer. But, because it's updating itself I will use an Instead Of trigger that is separate from the table's Insert & Delete triggers.
The table has a primary key defined such that 'In-Place' updates will be used, that was a technique for reducing disk activity way back when and I can find no reference to it in SQL2005 BOL.
My question is, does the 'Inserted' table still exist for 'In-Place' updates? Or more basically, does the In-Place update still exist?
Thanks.
Trigger To Handle Multirow Updates
Mar 2, 2006I am trying to implement trigger which can handle multirow updates and which is running on replicated table. So I want it never fails as trigger failure brakes replication.
So:
CREATE TRIGGER on_person_update
BEGIN
-- create temp table
-- populate temp table with Inserted values (I do not need Deleted as PK never change)
COMMIT TRAN
-- Am I right that this insures updates on replicated table will never be rollback after this commit?
BEGIN TRAN A
-- Make a checkpoint here to be able to rollback at any time to this point if something wrong inside loop.
SAVE TRAN MyTran
-- Start looping in temp table
-- RUN DML statement to make neccesary changes for each record in temp table
-- Does it make any sense to do this (IF @ERR below)? When I am trying in DML insert string value into integer column it never gets to IF statement - terminates straight away.
-- Reason why I think I need it as this trigger might be called by another trigger and top level trigger will get an error and can make a decision based on this.
IF @ERR <> 0
BEGIN
ROLLBACK TRAN MyTran
RAISERROR('Insert or Update failed in on_person_sls_update trigger with error: %s', 16, 1, @ERR)
RETURN
END
-- End looping temp
-- Do I need here COMMIT TRAN A or trigger will make commit anyway?
END
Why all of this?
Data changed on distributor and arrive to subscriber as a transaction.
We have a trigger on replicated table which will update replicated table in any way but after that it will update another database on subscriber.
This trigger should be able to handle multirow updates.
When this trigger updates another database it runs DML which fires other triggers so they become nested, if I am right. Our trigger should always accept changes from distributor as if it fails replication brakes but after data saved in temp table none or all changes have to be made.
May be I am copmpletely wrong with this template - hope somebody will help.
Thank you,
Igor

How To Catch Multiple Updates Done To A Table With A Trigger?

SQL Server 2012 :: Trigger For Updates On A Row Using Previous Record Value?
Mar 9, 2015I am looking to update a record from a previous row. So if there is a value of total goods in week 1, i want that value to carry forward to the value of goods in week 2. Is there any SQL as an example of the best way to accomplish this? I can query it using lag() which works great but i need the source data itself to update as the end-users are accessing the data via lightswitch, so when they save a change, i want the trigger (or whatever you recommend) to update the source table.

Oct 13, 2015I would like to have a dynamic trigger on INSERT, UPDATE and DELETE. (each their own trigger).
What i want, is the trigger to log what has happened with the record. For the insert trigger, i would like to select all columns and put them in 1 column to my logging table. For the update trigger, i need the same, however for both of the old and new items.
For example:
CREATE TABLE [dbo].[TRIGGER_TEST](

INSERT INTO [dbo].[TRIGGER_TEST]
([COLUMNB]
,[COLUMNC]
,[COLUMND]
,[COLUME])

Logging To Event Viewer Fails But SQL Server Logging Works OK - Why?
Jun 18, 2007Greetings,
I am developing a package on my local workstation. I have defined two logging service providers. One is for SQL Server and the other is for the Windows Event Log. I am using the Dts.Log method in a script task to write log entries.
Logging is working properly with the SQL Server provider and rows are being inserted into the sysdtslog90 table. However, the only events that are being logged in the Windows Event Log are the package start and end events which I believe SSIS is doing automatically anyway.
Is there something I need to do to enable WIndows Event Log logging other than defining a log provider and making sure it is checked active? Won't SSIS write to two different logs with one Dts.Log call? Any ideas on what might be going wrong with my approach?
Thanks,
BCB
Logging Package Name For Any Event In Sysdtslog90 Logging Table
Oct 17, 2007
Hi,
I decided to use the SQL Server log provider to store logging data of all my Integration Services packages. I also created some reports about this data for operating purposes.
I have a problem occurs the name of the executing package is not always written to the log,but the name of the single task which failed. But that is not very useful information for operating, because I do not see any chance to get the name of the package by the information which is logged in the sysdtslog90 table in the database which I defined for SSIS Logging.
How do I configure the package to always log the package information into the table, too?
Best regards,
Stefoon

How Can I Do A Multiple Insert Or Multiple Updates Or Inserts And Updates To The Same Table..

I have data that i am getting through a dbf file. and i am dumping that data to a sql server... and then taking the data from the sql server after scrubing it i put it into the production database.. right my stored procedure handles a single plan only... but now there may be two or more plans together in the same sql server database which i need to scrub and then update that particular plan already exists or inserts if they dont...

Transact SQL :: STATIC Defines A Cursor That Makes Temporary Copy Of Data To Be Used By Cursor
Aug 12, 2015 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.
Dynamic Cursor Versus Forward Only Cursor Gives Poor Performance
Jul 20, 2005Hello,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

This works fine, but I'm wondering if there's an easy way to put the script in the batch file, so users don't have to worry about putting the script in the C drive. I tried getting rid of the i parameter and pasting the script from the sql file into the batch file, but it didn't work.

Jul 20, 2005I 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

Nov 14, 2006Hey,
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.
Trouble With Update Trigger Modifying Table Which Fired Trigger

Dec 5, 2006This Audit Trigger is Generic (i.e. non-"Table Specific") attach it to any tabel and it should work. Be sure and create the 'Audit' table first though.

The trick was getting the Table Name and the Primary Key Columns.
I hope this code is found useful.

I want to be able to create a trigger that updates table 2 when a row is inserted into table 1. However I€™m not sure how to increment the ID in table 2 or to update only the row that has been inserted.

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
1 To Many Updates
Feb 5, 2004I have a web form that collects details on books (as an example), and in that form is a checkboxlist that displays an entry for each potential author in the database (as an example).
The user can obviously tick as many authors as they want to represent Authors of the book. The ticked entries form the entries in the BooksToAuthors table which only has BookID and AuthorID columns.
I have a number of questions:
How do I take what is in the CheckBoxList to the database and how does this relate to Stored Procedures?
Do I fill the checkbox selections into an Array? How do I get these 'many items' to a Stored Procedure that runs a transaction to put the book in and then the many rows in AuthorsToBooks.
What is being passed? Can you pass an array or something to a stored procedure?
