Hello,
Has anyone attempted to use the MBSA 1.2.1 tool in a clustered SQL Server 2000 SP3 environment? Is this possible?
The tool connects, sees the services, verifies the sa password vulnerability, but when it gets to the "sysadmin" issue, it returns the following error: [Microsoft][ODBC SQL Server Driver][Shared Memory]SQL Server does not exist or access denied.
I am logging on with the domain user with admin rights locally to the virtual SQL Server.
My Windows login is a domain administrator. I run MBSA and ask it to scan only my computer. I have removed Builtinadministrators from the sysadmin role in my SQL Server 2000 installation. The login is still there. MBSA is still able to get into my SQL Server and report that there is a guest user in Northwind and Pubs. It does not, however, report on the logins with weak passwords, which it did when BuiltinAdministrators was a member of sysadmins. This leads me to believe that it does use the BuiltInAdminstrators login to access the SQL Server. Is this correct?
We have a table, which has one clustered index and one non clustered index(primary key). I want to drop the existing clustered index and make the primary key as clustered. Is there any easy way to do that. Will Drop_Existing support on this matter?
I 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.
We are going to use SQL Sever change tracking. The problem is that some of our tables, which are to be tracked, have no primary keys. There are only unique clustered indexes. The question is what is the best way to turn on change tracking for these tables in our circumstances.
I desire to have a clustered index on a column other than the Primary Key. I have a few junction tables that I may want to alter, create table, or ...
I have practiced with an example table that is not really a junction table. It is just a table I decided to use for practice. When I execute the script, it seems to do everything I expect. For instance, there are not any constraints but there are indexes. The PK is the correct column.
CREATE TABLE [dbo].[tblNotificationMgr]( [NotificationMgrKey] [int] IDENTITY(1,1) NOT NULL, [ContactKey] [int] NOT NULL, [EventTypeEnum] [tinyint] NOT NULL,
I have created two tables. table one has the following fields,
Id -> unique clustered index. table two has the following fields, Tid -> unique clustered index Id -> foreign key of table one(id).
Now I have created primary key for the table one column 'id'. It's created as "nonclustered, unique, primary key located on PRIMARY". Primary key create clustered index default. since unique clustered index existed in table one, it has created "Nonclustered primary key".
My Question is, What is the difference between "clustered, unique, primary key" and "nonclustered, unique, primary key"? Is there any performance impact between these?
Hi there, I have a table that has an IDENTITY column and it is the PK of this table. By default SQL Server creates a unique clustered index on the PK, but this isn't what I wanted. I want to make a regular unique index on the column so I can make a clustered index on a different column.
If I try to uncheck the Clustered index option in EM I get a dialog that says "Cannot convert a clustered index to a nonclustered index using the DROP_EXISTING option.". If I simply try to delete the index I get the following "An explicit DROP INDEX is not allowed on index 'index name'. It is being used for PRIMARY KEY constraint enforcement.
So do I have to drop the PK constraint now? How does that affect all the tables that have FK relationships to this table?
I have a really super slow stored proc that does something simple. it updates a table if certain values are received.
In looking at this the matching is done on the Primary Key, which is set as a Clustered index, looking further I have another constraint, that sets the same column to a Unique, Non-Clustered.
I am not sure why this was done, but it seems to be counter productive. I have read only references to Which one is better on a primary key, but not can their be both and if it is "Smart".
I've a table with primary key defined as non-clusterd, now without dropping it can I modify the existing index to clustered through tsql as I had to write some migration script and in that script I wanna do this.
I would like to find information on Clustered and Non-clustered indexes and how B-trees are used. I know a clustered index is placed into a b-tree which makes sense for fast ordered searching. What data structure does a non-clustered index use and how? I tried to find info. on the web but couldn't get much detail...
I have a table<table1> with 804668 records primary on table1(col1,col2,col3,col4)
Have created non-clustered index on <table1>(col2,col3,col4),to solve a performance issue.(which is a join involving another table with 1.2 million records).Seems to be working great.
I want to know whether this will slow down,insert and update on the <table1>?
SELECT a.AssetGuid, a.Name, a.LocationGuid FROM Asset a WHERE a.AssociationGuid IN ( SELECT ada.DataAssociationGuid FROM AssociationDataAssociation ada WHERE ada.AssociationGuid = '568B40AD-5133-4237-9F3C-F8EA9D472662')
takes 30-60 seconds to run on my machine, due to a clustered index scan on our an index on asset [about half a million rows]. For this particular association less than 50 rows are returned.
expanding the inner select into a list of guids the query runs instantly:
SELECT a.AssetGuid, a.Name, a.LocationGuid FROM Asset a WHERE a.AssociationGuid IN ( '0F9C1654-9FAC-45FC-9997-5EBDAD21A4B4', '52C616C0-C4C5-45F4-B691-7FA83462CA34', 'C95A6669-D6D1-460A-BC2F-C0F6756A234D')
It runs instantly because of doing a clustered index seek [on the same index as the previous query] instead of a scan. The index in question IX_Asset_AssociationGuid is a nonclustered index on Asset.AssociationGuid.
The tables involved:
Asset, represents an asset. Primary key is AssetGuid, there is an index/FK on Asset.AssociationGuid. The asset table has 28 columns or so... Association, kind of like a place, associations exist in a tree where one association can contain any number of child associations. Each association has a ParentAssociationGuid pointing to its parent. Only leaf associations contain assets. AssociationDataAssociation, a table consisting of two columns, AssociationGuid, DataAssociationGuid. This is a table used to quickly find leaf associations [DataAssociationGuid] beneath a particular association [AssociationGuid]. In the above case the inner select () returns 3 rows.
I'd include .sqlplan files or screenshots, but I don't see a way to attach them.
I understand I can specify to use the index manually [and this also runs instantly], but for such a simple query it is peculiar it is necesscary. This is the query with the index specified manually:
SELECT a.AssetGuid, a.Name, a.LocationGuid FROM Asset a WITH (INDEX (IX_Asset_AssociationGuid)) WHERE a.AssociationGuid IN ( SELECT ada.DataAssociationGuid FROM AssociationDataAssociation ada WHERE ada.AssociationGuid = '568B40AD-5133-4237-9F3C-F8EA9D472662')
To repeat/clarify my question, why might this not be doing a clustered index seek with the first query?
I have an environment of SQL Server 2K5 and 2000 servers. The environment is mostly data warehouse than transactional. There are some applications working continiously to provid reports. The servers must be up and running.
I have to provide high availability, monitor performance, and minimize down time. Is there any "really good" tool for a DBA for this environment? I would like to hear your experience with the tool you are using. Any practical suggestion is highly appreciated.
Thanks,
[1/29/07] It's first time on this forume for me that I had no reply for about 4 days! Any idea? Any experience to share?
Quest Software has released a SQL Server version of its highly popularOracle tool - TOAD. It is freeware! You can see more about it athttp://www.toadsoft.com/toadss.html and download it athttp://www.toadsoft.com/toad_ss.zip.
So 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?
I've run into a problem after upgrading production servers running under Microsoft Cluster Server, Windows Enterprise Server 2003 SP1, and SQL Server 2005 SP1 Enterprise Edition.
Once I completed the upgrade and applied the patch, I needed to examine the values set in the Features component of the Surface Area Configuration tool. The tool attempts to connect to localhostinstancename, but reports the following error:
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error:26 - Error Locating Server/Instance Specified)(Microsoft SQL Server)
I'm logged into the virtual server via Remote Desktop, but the SAC tool thinks I'm logged into the physical server supporting the virtual server. I seem to be caught between a rock and a hard place here, as I can't enable remote connections without first gaining access on the server itself.
Back in July I released the (then) latest version of SsbAdmin. For you who don'r know what it is; it's a tool which allows you to graphically administer SQL Server Service Broker.
I have now uploaded a new version which is compiled against the released versions of SQL Server 2005 and .NET 2.0.
You can download it from here: [0].
After download, un-zip to some directory and read the README.doc file.
We get the following error when we try to run the program:
SQL Server does not exist or access denied. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Data.SqlClient.SqlException: SQL Server does not exist or access denied.
We have the SQL Profiler running and we don't see any connection being made. Any help would be appreciated!
Hi I am facing problem with installing SQL Server CE Server Tool,

I am sure that i have running SQL Server 2000 SP 4 (MSDE also SP 4) , IIS (Version 5.1) is also working fine , and one more thing i am trying to install SQL Server CE Server Tool setup is "sqlce20sql2ksp4.exe" (Which i downloaded from microsoft site.).Here all the requirement is fulfill but i dont know what is going to wrong.
I wasted my 2 days behind solving this issue , now i am tiered ,So please any one have solution for this issue. Help me please.
I have installed "SQL Server 2000 SP 4" to SQL server and it is running fine.
But when i install the "SQL Server CE version 2.0 Update for use with IIS and SQL Server 2000 SP4", i get below error: "SQL Server CE Tool is compatible only with SQL Server 2000 Service pack 1 and higher.

I have go thougth few articles in the forum, try to open the sqlce20sql2ksp4.exe file and then run only the MSI, but still fail.
By the way, i found that the sqlce20sql2ksp4.exe does not include any MSI, it is a direct executable file.

Can anyone recommend a good tool for administering my database ? It is located on a hosting service, however, they donot allow the use of the SLQ server admin tool since there are security concerns..
I am looking for an ASP.NET tool that allows me to access a SQL Server remotly. We have created a database and would like to begin populating the tables before development of our site. The main funtionality I am looking for is to be able to view all tables within a database in the SQL Server. Also, I would like to be able to insert data into these tables. Is anyone aware of a tool like this?
HI Everyone, I need to ask you a question about T-Sql Debugger. I have installed the sqldbreg.exe and sqldbg.dll in the program filesmicrosoft sharedsql debuggin directory.
