Anybody had experience dropping the system generated index?
I tried to drop some auto-generated index which usually have name like _WA_Sys_[column name}_07F6335A. Then I follow the table.index name rule. It always show no such index exists in the database. But I can query these indexes in sysindexes and verify they are there. What went wrong?
Help appreciated very much.

Hi,
I get the following error message while droping unique index.
Server: Msg 3723, Level 16, State 5, Line 1
An explicit DROP INDEX is not allowed on index 'dbo.ALEG.IX_ALEG'. It is being used for UNIQUE KEY constraint enforcement.
Could you please how the index can be droped.
Thanks
I ran a SP that lists fragmented tables in our DB which listed almost all the tables and indexes in the DB. The list includes index names that start with "_WA_Sys_tablecolumn name_.....". Are these SQL Server generated indexes or are these statitics on the tables? What are they? If these are system generated indexes as I thought they were, how are they generated? Can these indexes be dropped or should one want to? IF so, how? Any effect on the DB performance if dropped?
Thanks for your advise.

Why are two log files generated when using a Text Log Provider with a Connection String property set to the following expression?
"c:\" + @[System::ExecutionInstanceGUID] + ".log"
I've set up package logging with a view to getting a unique, and linkable log. However, two files are always generated, no matter what the DelayValidation settings may be on the connection manager, file, and package tasks.
Hi.
Is there a way to supress a system generated error messages?
I have a stored procedure that I'm executing from Query Analyzer that updates a table and potentially generates a foreign key violation. I am trapping and handling the error, but the system generated message still displays. Is there a way to supress these messages (other than pre-checking for the condition prior to updating)?
Thanks,

I need to be able to verify that SSMS recognizes ONLY system generated session identifiers.
Where in the configuration of the DBMS can i see evidence of this setting, and / or change it if necessary?
We have implemented a very small reporting database which has a main table that started off small and has now grown to around half a million rows. Initially, there were no indexes on the table apart from a clustered index, but as the data has grown, performance has dropped and so we have added a number of indexes. This has resolved the performance issues.
Before creating the indexes SQL Server had auto created a number of statistic objects (_WA_Sys_000... etc). After creating the indexes, new statistic objects where created for the new indexes. In some cases, there are duplicate statistics (auto and index) for the same columns.Should I go through and drop the duplicate auto statistics? Will having duplicates cause issues at all?
I have been searching for a means to change the System Failure Error Check policy that comes as part of the Best Practice policies. I want to look back 24 hours. The WQL query shipped with the policy doesn't have a WHERE clause component that looks at TimeGenerated. That query looks like:
IsNull(ExecuteWql('Numeric', 'rootCIMV2', 'select EventCode from Win32_NTLogEvent where EventCode=6008 and Logfile="System"'), 0)
After searching for an example of how to do this and not finding any that are specific to PBM, I decided to fall back to a very basic approach - use wbemtest.exe to try out where clause additions and see how they work, then plug the result into the policy and see if it works. As a start, I tried the following query using wbemtest.exe:
select Event Code
from Win32_NTLogEvent
where EventCode = 6008
and Logfile = 'System'
and TimeGenerated > '20130101010000.000000–000'
This works great in wbemtest.exe. My next step was to plug this into the policy condition expression as follows: IsNull(ExecuteWql ('Numeric', 'rootCIMV2', 'select EventCode from Win32_NTLogEvent where EventCode=6008 and Logfile="System" and TimeGenerated > "20130101010000.000000–000"'), 0)
When I try to manually evaluate this policy in SSMS, I receive an "Invalid Query" error message.I assume that SWbemDateTime isn't available to use inside Policy Based Management policies. All the examples of how to handle the kind of dynamic date creation I have seen are for use in PowerShell, VBScript, or SSIS. I've played with using DateDiff, DateAdd, and GetDate inside the query string, with no success.
Why does the ExecuteWql above fail?Is it at all possible to dynamically generate a datetime (say, 24 hours ago) as part of the query string parameter of the ExecuteWql call?What might that look like?
I am having problem to find the right syntax to DROP a column with contrainst and recrate it
I get an error

GO
ALTER TABLE [dbo].[myTable] WITH NOCHECK ADD
myDate datetime CONSTRAINT [DF_myDate] DEFAULT (GetDate())
GO
Query Analyser says :
Server: Msg 5074, Level 16, State 1, Line 5
The object 'DF_myDate' is dependent on column 'myDate'.
Server: Msg 4922, Level 16, State 1, Line 5
ALTER TABLE DROP COLUMN myDate failed because one or more objects access this column.
Server: Msg 2705, Level 16, State 4, Line 2
Column names in each table must be unique. Column name 'myDate' in table 'dbo.myTable' is specified more than once.

I have two transaction log files, one on C drive and other on D drive. I want to drop the file from that database that is on C drive. Can anyone help me out on this with complete syntax.
I have taken a down time of one and half hour to accomplish this task
Here is what think
Take a full database backup
Take transaction log backup
Shrinkfile using DBCC with truncateonly option
emptyfile using dbcc or drop file using alter database remove

Help.
There is a index: CustomerInfo_1
with keys: customerId, EnteryDate DESC
I could not find where the order of index key (i.e. whether the key is ascending or descending) is stored?
I tried system tables such as sysindexes and sysindexkeys tables. But could not find it.
Any help in this regard will be truly appreciated.
Thank you.

Hi,
SQL Server 2005 has a new very useful feature for creating non-clustered indexes called INCLUDE <columns> which are very helpful when trying to create covering indexes.
Does anyone know of a way to retrieve these INCLUDE columns through any of the system metadata tables? The sp_helpIndex stored procedure is what I currently use but that only returns the (sorted) index columns and not the include columns.
Thanks in advance,

How can I add entities to my Sqlce- database?

I'm familiar with how to check for the existence of a table before dropping it using the following command:
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[xxx]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[xxx]
How does one check for the existence of a temp table (using # syntax) before dropping it? I've tried various flavors of this command and none work. One flavor is
use tempdb
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[#xxx]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[#xxx]
CREATE TABLE #xxx (
NumID INTEGER IDENTITY(1,1),
Exhibitor_Id INTEGER NOT NULL,
Company_Id INTEGER NOT NULL
)
Thanks.

I have a database that is about 300 gig. I am setting up replication to a reporting server. We are doing a series or mock loads and I will need drop the tables and reload the main database a few times before we go live. To do that I plan to stop replication and drop all the articles, drop the subscription, then load the new data, then reinitialize and restart replication.
The first time I tried to do this, when I drop the articles, it seems to be trying to "clean up" the distribution database on the reporting server and that is taking a couple of hours to do. The disruption database is about 40 gig.
Is this correct behavior in SQL2005 replication? Is there a way to avoid this? I have all the replication pieces scripted out and would like to just drop replication, reload, and then run my scripts to recreate replication. But this "clean up" is going to cause me a lot of headache if I don't figure out what is going on.
Am I going down the wrong road here? Is there an easier way to do this? Any comments would be great!!!!
Thanks in advance for any help.

Ok guys, I am trying to install Sql server 2005 on Vista but I am still stuck with this warning message in the System Configuration Check during Sql server 2K5 installation :
SQL Server Edition Operating System Compatibility (Warning)
Messages
* SQL Server Edition Operating System Compatibility
* Some components of this edition of SQL Server are not supported on this operating system. For details, see 'Hardware and Software Requirements for Installing SQL Server 2005' in Microsoft SQL Server Books Online.
Now, I know I need to install SP2 but how the hell I am going to install SP2 if Sql server 2005 doesn't install any of the components including Sql server Database services, Analysus services, Reporting integration services( only the workstation component is available for installation)?
Any work around for this issue?
P.S.: I didn't install VS.NET 2005 yet, can this solve the problem?

I am using Full Text Index to index emails stored in BLOB column in a table. Index process parses stored emails, and, if there is one or more files attached to the email these documents get indexed too. In result when I'm querying the full text index for a word or phrase I am getting reference to the email containing the word of phrase if interest if the word was used in the email body OR if it was used in any document attached to the email.
How to distinguish in a Full Text query that the result came from an embedded document rather than from "main" document? Or if that's not possible how to disable indexing of embedded documents?
My goal is either to give a user an option if he or she wants to search emails (email bodies only) OR emails AND documents attached to them, or at least clearly indicate in the returned result the real source where the word or phrase has been found.
Hi,I have a few things on my databases which seem to be neither true systemobjects or user objects - notably a table called 'dtproperties' (createdby Enterprise manager as I understand, relating to relationship graphingor something) and some stored procs begining with "dt_" (some kind ofsource control stuff, possible visual studio related). These show up whenI use"exec sp_help 'databaseName'"but not in Ent. Mgr. or in Query Analyzer's object browser, and also notin a third party tool I use called AdeptSQL. I am wondering how thosetools know to differentiate between these types of quasi-system objects,and my real user data. (This is for the purpose of a customized schemagenerator I am writing). I'd prefer to determine this info with systemstored procs (ie sp_help, sp_helptex, sp_...etc) but will dip into thesystem tables if needed.Thanks,Dave
