Thanks all.

SQL Server 2012 :: Rule Of Thumb When To Disable Indexes?
Jun 19, 2014It's often said or done that when inserting or updating into a 'large' table that disabling the non-clustered indexes can is needed for performance.
Now I know the obvious way to find out if this is best or not is by testing the different options. I was wondering if there was a rule of thumb to this?
Say you have a table with half a billion rows and 4 non-clustered indexes and are only updating half a million rows then sometimes disabling every night and re-enabling can take way more time than the actual update. Haven't found an articles advising to disable them when a table is over X rows and you are updating Y% of them...
Removal Of Selected Indexes / Script Index Create For List Of Indexes
Jul 1, 2014I'm working to improve performance on a database I've inherited, and there are several thousand indexes. I've got a list of ones which should definitely exist within the database, and I'm looking to strip out all the others and start fresh, though this list is still quite large (1000 or so).
Is there a way I can remove all the indexes that are not in my list without too much trouble? I.e. without having to manually go through them all individually. The list is currently in a csv file.
I'm looking to either automate the removal of indexes not in the list, or possibly to generate the Create statements for the indexes on the list and simply remove all indexes and then run these statements.
As an aside, when trying to list all indexes in the database, I've found various scripts to do this, but found they all seem to produce differing results. What is the best script to list all indexes?
A Question About Clustered Indexes Forcing Rebuild Of Non-clustered Indexes.
Sep 18, 2007So I'm reading http://www.sql-server-performance.com/tips/clustered_indexes_p2.aspx and I come across this:
When selecting a column to base your clustered index on, try to avoid columns that are frequently updated. Every time that a column used for a clustered index is modified, all of the non-clustered indexes must also be updated, creating additional overhead. [6.5, 7.0, 2000, 2005] Updated 3-5-2004
Does this mean if I have say a table called Item with a clustered index on a column in it called itemaddeddate, and several non-clustered indexes associated with that table, that if a record gets modified and it's itemaddeddate value changes, that ALL my indexes on that table will get rebuilt? Or is it referring to the table structure changing?
If so does this "pseudocode" example also cause this to occur:
sqlstring="select * from item where itemid=12345"
rs.open sqlstring, etc, etc, etc
rs.Fields("ItemName")="My New Item Name"
rs.Fields("ItemPrice")=1.00
rs.Update
Note I didn't explicitly change the value of rs.fields("ItemAddedDate")...does rs.Fields("ItemAddedDate")=rs.Fields("ItemAddedDate") occur implicitly, which would force the rebuild of all the non-clustered indexes?
SQL Server 2008 :: Logic To Rebuild Only Clustered Indexes / Skipping To Rebuild Non Clustered Indexes In Same Table
Jun 25, 2015I have a requirement to only rebuild the Clustered Indexes in the table ignoring the non clustered indexes as those are taken care of by the Clustered indexes.
In order to do that, I have taken the records based on the fragmentation %.
But unable to come up with a logic to only consider rebuilding the clustered indexes in the table.
create table #fragmentation
(
FragIndexId BigInt Identity(1,1),
--IDENTITY(int, 1, 1) AS FragIndexId,
DBNAME nvarchar(4000),
TableName nvarchar(4000),
[Code] ....

At first, I thought the solution was sysmail_stop_sp... but if I use this... calls to sp_send_DBMail fail with the following message:
Mail not queued. Database Mail is stopped. Use sysmail_start_sp to start Database Mail.
I'd like the emails to be queued... I just want to postpone sending them. Anyone know how to do this?

I read somewhere that it had to do with the SQL Server service account and that if you change it to a Domain Administrator it would and it does, but I can not believe the solution. I would say that this even started happening after we applied SQL 2005 Service Pack 2.
Has anyone else seen this problem. Do I really need to make it a Domain Administrator?

View 4 Replies View RelatedTrigger Disable
Aug 9, 2007Sorry to reopen a post, but I'm having the same problem. Worse, I can't change the trigger code right now.
My concerns with disabling triggers are:
1) DISABLE TRIGGER affects all sessions, not just the session doing the mass load
2) DISABLE TRIGGER is permanant until re-enabled, so if the mass load process fails (and if our TRY/CATCH blocks aren't perfect), then the triggers would remain disabled for normal OLTP use.
Any ideas on ways around this? I can identify all the work the triggers would have done and do it on my own. The problem is getting them not to do it!
Disable Grouping
Aug 20, 2007I would like to be able to disable grouping depending on the value of parameter. At the moment I have the following expression for grouping:
=IIf(Parameters!Group2.Value.equals(""), false, Fields(Parameters!Group2.Value).Value)
What I am trying to do is if the value of the Group2 parameter = "" turn off grouping. Group2 is assigned a value from the following custom code:
Function Group2Value() As String
Dim Group As String
Group = ""
Select Case Report.Parameters!ReportType.Value
Case "1"
Group = ""
Case "2"
Group = "CategoryID"
Case "3"
Group = "StockFamilyID"
Case "4"
Group = "GroupID"
Case "5"
Group = ""
Case "6"
Group = "SaleableGLCodeID"
End Select
Return Group
End Function
However this is not working.
Can grouping be disabled and if so what am I doing wrong?
Thanks in advance.

SQL Server (7.0) is showing the connection as runnable but it seems as if nothing is being removed. Am I missing something? Should I have done something else before running the wizard? I can't even kill the SPID.
Can anyone help or offer some advice?

Can Not Disable Replication In SQL7
Oct 24, 2000Hi, guys
I have an urgent problem in replication.
Yesterday I set up a Transaction replication with 1 publication
Server A (publisher)(push)(SQL 7)
Server B (distributor and subscriber)(SQL 7)
The replication was succesful and the suscriber can get correct data.
This morning I found the Red sigh in replication mornitor/miscellaneous agents.The error message is:
"The job failed. Unable to determine if the owner (domain nameuser ID) of job Agent history clean up: distribution has server access (reason: Could not obtain information about Windows NT group/user 'domain name'. [SQLSTATE 42000] (Error 8198))."
I tried to use the 'disable publishing and distribution wizard' to disable this replication, but it did not finish and the screen jusr freeze. I used the task manager to end the task.
then I check the replication monitor, the publication was gone but the RED sigh still there.
I tried to use sp_dropdistpublisher to drop a Publisher
but it said "the server A is not a distributor"
I tried to use sp_dropdistributiondb to delete the distribution database.
but it said "Could not drop the distribution database 'distribution'.
This distributor database is associated with a Publisher."
I tried to use sp_dropdistributor to remove the Distributor .
but it said "Could not drop the Distributor 'Server B'.
This Distributor has associated distribution databases."
Any suggestion? Thank you in advance.

Disable Specific Trigger
Jul 26, 2004I have a dilema, I need to have a delete trigger enabled to track user deletes to update an external history table. However, when the posting process runs for the table for which the delete trigger runs, all the records from that table are deleted. Th end result is that instead of capturing the specific deletes, it shows all recods being deleted. I know you can disable foreign keys and triggers as a whole, can you do it for specific triggers?
