I wrote an update trigger to set a "Last Updated" value in a table.
I think that this may be causing optomistic concurrency errors when a recordset is updated more than once without being refreshed.
1) Does it make sence that this could be the problem
2) Is there a good way around this?
thanks
Jacob
Hi - I am using the following: (.NET 2.0, Oracle 10g, VWD 2005 Express) Here is the problem I am having:I am using Optomistic Concurrency to ensure the validity of my data. Unfortunately, on an update, the data is never being updated and the conflict detection is always occurring. I've finally found the source of the problem I believe.I think that the SqlDataSource control is doing the following (in the case of nulls):where fielda='' and fieldb='' and fieldc=''and it should be doing:where fielda is null and fieldb is null and fieldc is nullThe reason I believe this is the problem is because I tested by doing a select statement. I have yet to figure out how to efficiently debug the SqlDataSourceControl with Oracle. Using XE (web interface) to monitor the SQL statements being sent to the Oracle server, does not yeild the expected results. Statements look like this (where fielda = :fielda and fieldb = :fieldb and fieldc = :fieldc), where I would have thought it would look like (where fielda='possible value' and fieldb = 'possible value' and fieldc = 'possible value')Please help!
View 11 Replies View RelatedI have a table where I count how many emails of a given type are sent out each day. This incrementing is wrapped in a sproc that either inserts a new row, or updates the existing row. The column that counts the value is named Count of type INT.
Below is the sproc, seems like a straightforward thing. However, I'm seeing email counts higher than they should be when there's a high number of concurrent executions of the sproc. I'm pretty sure it's not a problem in the calling code, so I'm wondering about the UPDATE statement, since it updates a column based on the value of the column. I would think this should work since it's wrapped in a SERIALIZABLE transaction, anybody have further insight?
SQL Server 2005 by the way.

Hello,
I'm trying to create a trigger that would reset the database column, A_STATUS from 'True' to 'False' when the appointment date, stored in the column, MY_DATE of the database table has been reached or passed. A_STATUS has a bit datatype.
My code is as below:
Code Snippet
CREATE TRIGGER ACLT_STATUS
ON dbo.MY_CONTACTS
AFTER INSERT, UPDATE, DELETE
AS
UPDATE dbo. MY_CONTACTS
SET A_STATUS = 'False'
WHERE (DATEDIFF(mi, 0, MY_DATE) <= DATEDIFF(mi, 0, GETDATE()))
When I run it, I get the error below:
The data in row 1 was not committed.
Error Source: Microsoft.VisualStudio.DataTools.
Error Message: The row value(s) updated or deleted either do not make the row unique or they alter multiple rows(1 rows).
Thanks.

if there is an error in the trigger then the update to the table does not happen. is there a way to make sql ignore errors in a trigger and still update the table
View 4 Replies View Relatedhi!
I have a big problem. If anyone can help.
I want to retrieve the last update time of database. Whenever any update or delete or insert happend to my database i want to store and retrieve that time.
I know one way is that i have to make a table that will store the datetime field and system trigger / trigger that can update this field record whenever any update insert or deletion occur in database.
But i don't know exactly how to do the coding for this?
Is there any other way to do this?
can DBCC help to retrieve this info?
Please advise me how to do this.
Thanks in advance.

I have a table where table row gets updated multiple times(each column will be filled) based on telephone call in data.
Initially, I have implemented after insert trigger on ROW level thinking that the whole row is inserted into table will all column values at a time. But the issue is all columns are values are not filled at once, but observed that while telephone call in data, there are multiple updates to the row (i.e multiple updates in the sense - column data in row is updated step by step),
I thought to implement after update trigger , but when it comes to the performance will be decreased for each and every hit while row update.
I need to implement after update trigger that should be fired on column level instead of Row level to improve the performance?
Hi,
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,

I've to write an trigger for the following action

statut_tiers to 1
and date_cloture to the same date as entered
the same action has to be done when an update is done and the valeur is set to 1 for the statut_tiers and a date entered in the field date_clture

Is there a way I can stop a form from inserting or updating a record when there is an error. I have an sql 2000 DB. I have noticed that if the db field can handle 50 characters and the form field has no limit on the number of characters no errors are displayed to the user if they try to use more than the 50 characters in the textbox. The record is not saved. None of the fields are saved. I do notice the autonumber generated is skipped by the db. That is, the next autonumber for a successful insert skips the logical next number. How do I capture this error, or any save error and return the user back to the form? Yes, I have limited the number of characters a user can type on the textbox now, but I would really like to catch save or insert errors. I use asp.net 2.0 and VB. I don't know C#. thanksMilton

Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.

hi!
i have a database with about 20 tables. i appended to each table a column "UpdatedOn", and i want to write a trigger to set the date of the update date in that column, using a trigger.
i want to avoid the trigger launching for the last column (UpdatedOn).
how can i detect the rows that changed, and modify only the update date/time?
i read something about TableName_Inserted and TableName_Deleted, but i would prefer to copy as generic as possible the data from there, meaning, not to write column names in my script.
another idea i thought about was to prevent the trigger executing if no other column except for UpdatedOn changed, but... i encounter some trouble, when i try to pass column name (as string) to UPDATE() function.(Error: Expecting ID or QUOTED_ID)
thank you in advance.
Hello all,
Thought I would post here in case anybody can give some information.
Here is the background information:
I have 2 tables (stores and sales) from the Pubs database in Sql Server 2000 copied down to a SQL Server CE database. There is no foreign key/primary key relationship between the 2 tables in the CE database.
Here are the update queries that cause the error:
UPDATE st
SET st.zip = 66668
FROM stores st
INNER JOIN sales sa ON st.stor_id = sa.stor_id
AND st.stor_id = 6380
Update stores SET stores.zip = 55555
FROM sales, stores
WHERE stores.stor_id = 6380
AND stores.stor_id = sales.stor_id
Here is the error message that is generated when I run the query (Param 0 and Param 1 change according to what column and line the FROM clause is in):
Error: 0x80040e14 DB_E_ERRORSINCOMMAND
Native Error: (25501)
Description: There was an error parsing the query. [Token line number,Token line offset,,Token in error,,]
Interface defining error: IID_ICommand
Param. 0: 2
Param. 1: 1
Param. 2: 0
Param. 3: FROM
Param. 4:
Param. 5:
I ran the 2 queries in SQL Query Analyzer in SQL Server 2000 and they worked just fine. I also created 2 new tables (stores1 and sales1) in SQL Server 2000 using the Select Into clause. The new tables were created from the sales table and stores table in the Pubs database. The new tables had no foreign key/primary key relationship.
I ran the queries again in Query Analyzer against the new tables and the queries produced no errors.
Any suggestions?
Thank you,

We are going insane trying to start Report Manager on a SQL Reporting Services 2000 installation. The programmer/admin who originally set this up for us is gone.
We recently upgraded a database/application server to a new server, causing the data source being used by reports in reporting services to no longer be valid. Unfortunately, we do not have access to the original report project to 're-deploy' with the corrected data source.
We desperately need to get the reports that are installed to retrieve their data from the new database location/machine. We understand this can be done by specifying a new data source in Report Manager. (To clarify, we have NOT moved the report servier installation or database, these remain in place - it's just the deployed reports that no longer point to the correct data source.)
For some reason, our Report Manager will no longer run - when we try to launch it, we get a windows login dialog - nothing will work here. We've tried both local and domain admins and constantly get ACCESS IS DENIED 401.3 error messages that we do not have permission/problems with ACL's.
We've gone so far as to allow EVERYONE read/write access to the ReportManager and ReportServer folders and the RS virtual directories, but nothing seems to help.
Can anyone help with this? Ideas on how to change our data source, or how to get back into Report Manager?
Since we are somewhat technical, but not experts, and don't have much more time to waste, we are willing to pay $500 for this project to someone willing to access the server and fix the problem so that the reports point to the correct database and restore access to Report Manager.
Thanks in advance for any help.
Hello All,
I've been adviced without much detail that the best way to handle updates is with an Update Trigger to write to an AuditTable.
I always thought it was better to avoid triggers.
I'm getting confused very fast in reading about triggers.
Could someone please point me in the right direction?
Thank you,
Tina
i am using address table to store the address of employees, agents, students; so can't use cascade update and delete. so i decided to use trigger but i got stuck here as well.
Here employeeid is the PK of employee id. so when it is updated, i want to update that id in corresponding address table as well.
so what i need is to find out the previous value of EmployeeID before updating to use in WHERE clause and new EmployeeID to use in SET clause.
<code>
CREATE TRIGGER [AddressUpdate] ON [dbo].[MCS_Employee]
FOR UPDATE
AS
IF UPDATE(EmployeeID)
BEGIN
UPDATE MCS_Address SET EmployeeID = 'i am stuck here; how to know the previous value?
WHERE EmployeeID = ???
END
</end>
ironically, PK in my table can be updateable as well.

Don't know much how you write them so if someone please could help or point me in right direction.
My plan is to always show the updated STATUS_ID in TOPIC while I have history in the THREAD TBL.

I have an update trigger on a table on my transactional database that inserts a row of data into another database (audit database)for any modification made on the transactional database.
So if i modify a row on tran db it will write the data modified as a new row in the audit db.
This works fine if I am updating only 1 row with each Update statement. However if I update more than 1 row (multiple rows) with the same Update statement, the update trigger only inserts the last row modified in the audit database. So I lose record of any other rows modified with the same update statement.
Is there a way by which i can change my Update trigger or something, so I get all the rows updated by 1 update statement inmy audit database???
Thanks a bunch,
Judy
