Hi, i have problem as subject says.
Db has table with 3 columns, ID, Key and Val. ID is primary key, Key has unique index and Val simple holds value in text format.
I have created DAL layer using .netTiers and CodeSmith. Generated procedures.sql has before every procedure set ANSI_NULLS to OFF.
When i read rows from table i print them on screen. When user changes value, that should also be updated in database.
When i select entity, its value is changed.
Here is code snipper.
Code Blockentity.Key = key;
entity.Value = value;
TransactionManager transactionManager = DataRepository.Provider.CreateTransaction();
try
{
transactionManager.BeginTransaction();
retVal = DataRepository.TestTableProvider.Update(entity);
transactionManager.Commit();
}
catch
{
transactionManager.Rollback();
throw;
}
I got an exception with message below:
UPDATE failed because the following SET options have incorrect settings: 'ANSI_NULLS'. Verify that SET options are correct for use with indexed views and/or indexes on computed columns and/or query notifications and/or xml data type methods.
Also, class which hold previous code snipper supports caching, by using some kind of SqlCacheManager, which is above SqlCacheDependecy class. Database service broker is started by
Code Block
ALTER DATABASE <DB_NAME> SET ENABLE_BROKER
Server is SqlExpress 2005.
Application is in ASP.NET 2.0.
I also noticed next.
On first run, previous code passes without errors. On second run, update error appears.
This is log from sql server.
Code BlockQuery notification delivery could not send message on dialog '{822C7891-736E-DC11-836B-005056C00008}.'. Delivery failed for notification '<qn:QueryNotification xmlns:qn="http://schemas.microsoft.com/SQL/Notifications/QueryNotificationhttp://schemas.microsoft.com/SQL/Notifications/QueryNotification">http://schemas.microsoft.com/SQL/Notifications/QueryNotification</A< A>>" id="1" type="change" source="database" info="restart" database_id="13" sid="0xE7C0751C9F7F6C4D9423096BBCC7FB69"><qn:Message>edd3e2dd-11ed-4d92-a0f4-5c674a90aecf;8b2095663cc6a9c297120e4c94d488555e97e54d</qn:Message></qn:QueryNotification>' because of the following error in service broker: 'The conversation handle "822C7891-736E-DC11-836B-005056C00008" is not found.'

I am getting the following error message:
[-E-19:42] Message: SELECT failed because the following SET options have incorrect settings: 'CONCAT_NULL_YIELDS_NULL, ANSI_WARNINGS, ANSI_PADDING'. Verify that SET options are correct for use with indexed views and/or indexes on computed columns and/or query notifications and/or xml data type methods.
I am using the following set options before the sp is created:
SET ARITHABORT ON
SET CONCAT_NULL_YIELDS_NULL ON
SET QUOTED_IDENTIFIER ON
SET ANSI_NULLS ON
SET ANSI_PADDING ON
SET ANSI_WARNINGS ON
SET NUMERIC_ROUNDABORT OFF
I looked on the internet and most of solutions were related to indexed views or computed columns. But I am neither using any indexed views nor computed columns. Also the same sp is working fine in one environment but giving the above error in another SQL server. I am using SQL Server 2005 with SP1.
Please help me in finding the cause & the resolution for this issue.

Hi
I am currently running the following query from Query Analyser, I am connected to Server_A and inserting records into
Server_B.Database_B.dbo.MyTable from Server_A .Database_A.dbo.TableRef
Insert into Server_B.Database_B.dbo.MyTable(Field1,Field2,Field3)
Select Field1_Ref,
Field2_Ref,
Field3_Ref
from Server_A .Database_A.dbo.TableRef
However Server_B.Database_B.dbo.MyTable is referenced within an Indexed View and whenever I run this query I get the following error:
Msg 1934, Level 16, State 1, Line 1
INSERT failed because the following SET options have incorrect settings: 'ARITHABORT'. Verify that SET options are correct for use with indexed views and/or indexes on computed columns and/or query notifications and/or xml data type methods.
I have tried setting ARITHABORT to ON & OFF within the Query and within the database properties but still recieve the same error.
Does anyone have any ideas on why this would not work?
Thanks

Hi,I am getting the following error when I run a stored procedure inwhich I am inserting/deleting data from a view that selects from aremote table.INSERT failed because the following SET options have incorrectsettings: 'ARITHABORT'The first statement in the stored procedure is 'set arithabort on'. Ialso ran 'set arithabort on' before creating the view.I read many articles ragarding the setting of arithabort. I set it forthe connection, for the database (alter database) and above all forthe server (sp_configure) but could not get around the above error.However, when I had made the setting using "sp_configure 'useroptions', 64" I was able to run the stored procedure successfully acouple of times. But, later when I had resest 'user options' to 0 andthen back to 64 just to reproduce the earlier error and confirm thatthe error does not come with the 'user options' to 64 setting I wasgetting the same error.Is there any way by which I can overcome the problem?Thanks,Iqbal

Hi,
I am contemplating creating a job to execute every 5 mins which will update index statisics if they are more than say 8% out. I would like to know what thoughts people have on this? i.e. pros and cons.
I like forward to what you have to say.
I have auto stats on. Our stats are often more than 10% out. At what level do you reckon the query plan might be effected by out of data stats?
Thanks
Jamie.

Hi,
It seems to me there are many ways to update statistics for a table. i.e. "sp_updatestats", "sp_recompile", "dbcc updateusage"
Can somebody tell me the difference between those commands and what's the best way for updating your statistics? Does reindexing update the statistics?
thx,
Wilfred van Dijk

Hi,
I am planning to change our current UPDATE STATISTICS strategy, which is auto stats ON. Our database is terrabytes sizes and some tables with millions of rows with over 200 indexes in one table. Some of these indexes are not really used. Most of the tables are very small.
Droping and creating new indexes are quite often used in our environment. So static script may not help.
How can I identify most frequently used indexes in a table?
With the Microsft recommended auto stats ON, what are the best other practices I can include to improve the effeciency?
Any help would be apprecited. It would be realy great if any of you can share some scripts to generates dynamic scripts.
best regards
Priw

On a SQL 7 sp 2 server, I have a database with about about 77,000 records, with automatic update statistics on inserting 1000 records took 43 minutes. With automatic update off, it took 23 minutes to insert the same 1000 records. On the same machine, I inserted 1000 records into 2 other databases with the same database structure and automatic update statistics on. On the second database, there are about 174000 records and it took 35 minutes to insert 1000 records. On the third database, there are about 93000 records and it took 19 minutes to insert 1000 records.
Why is the time so high on the first database?
What can be done to fix the problem?
Thank you.

I have a query that retrieves a single record from searching on two tables.
The statement goes like this...
select sum(amount) from Table1 A union Table2 B on a.id = b.id
where date < ### and date > #### and account = ###
As people are running a particular report, this statement is executed time and
time again to pull up the numbers necesarry for the report. When the report gets slow, I can speed it up by updating the statistics. My concern is that I'm having to update the statistcs every hour; otherwise, the query becomes slow. I have noticed that users are inserting data while users are running the report on one of the tables listed above. I'm sure that's making it become more fragmented and ultimately slowing down the query.
Do you have any suggestion on how I can make the union of these two tables faster? Or is there anything I could do to speed the query besides creating clusted indexes?
Any help would be appreciated....thank you

I am maintaining a large table with millions of rows that has two non clustered indexes and data changing frequently, I need to keep the indexes fresh. Update Statistics runs much quicker than Reindex. What is the appropriate situation for each and why?

Hi
We are upgrading from sql 7 to 2000.During the upgrade process do we have to do a reindexing of all tables or will update statistics take care of that.
Or do we have to do both?
What is the difference between reindexing and update statistics.

I am looking to run UPDATE STATISTICS for the first time, don't ask why it wasn't done prior please :(, on a set of large tables in our 346gb database whcih has been being populated with transactional data for the past 4 years. The tables contain 1.2, 35, 64, and 92 million rows. I have used the STAT_DATE function to determine that none of these tables have ever had update statistics run for them.
My question is how should I go about this process and what options should I be selecting when issuing the command? I assume that I must first run with the FULLSCAN paramater in order to initially generate statistics for the table then would assume that following this initial population I could run without any paramaters nightly against the tables in the database to keep statistics up to date. Any guideance you all could provide to a newb would be greatly appreciated.
Thanks! Scott Clark

Hi all,
We are using SQL Server 2005. The auto update statistics and auto create statistics for a database is set to ON. This database has a very heavy work load. When I checked the individual statitics , still the last updated statistics is in a old date value (few months ago).
Is it necessary to manually update the statistics for the same database? Or can we rely upon "auto update statistics" itself ?
Usually in what frequency the manual UPDATE STATISTICS should be run on production system which has heavy transactions ?
Thanks & Regards,
Hariarul

Hi all ,
We had a SQL server (2005) that was performing very bad . We thought of doing an UPDATE STATISTICS thinking that the response times would increase.
BUT , UNFORTUNATELY THE SERVER PERFORMANCE BECAME WORSE FROM BAD.
Ex : Stored procedures that took 2 minutes are running for 22 minutes now. Queris that ran for 17 seconds are running for 14 minutes now.
Anybody faced this kind of issue earlier ? Any help would be appreciated.

Dear Sql Server experts:First off, I am no sql server expert :)A few months ago I put a database into a production environment.Recently, It was brought to my attention that a particular query thatexecuted quite quickly in our dev environment was painfully slow inproduction. I analyzed the the plan on the production server (itlooked good), and then tried quite a few tips that I'd gleaned fromreading newsgroups. Nothing worked. Then on a whim I performed anUPDATE STATISTICS on a few of the tables that were being queried. Thequery immediately went from executing in 61 seconds to under 1 second.I checked to make sure that statistics were being "auto updated" andthey were.Why did I need to run UPDATE STATISTICS? Will I need to again?A little more background info:The database started empty, and has grown quite rapidly in the lastfew months. One particular table grows at a rate of about 300,000records per month. I get fast query times due to a few well placedindexes.A quick question:If I add an index, do statistics get automatically updated for thisnew index immediately?Thanks in advance for any help,Felix
