Nov 19, 1998hi, if exists (select * from sysobjects where id = object_id('dbo.MRDD_FINAL') and sysstat & 0xf = 3)
drop table dbo.MRDD_FINAL
This code was generated when I used the create a script to build a table from an existing table.
is there a way to check if a a table contains data or not,
The whole idea is to check if table A contains data, I need to truncate the table,otherwise I do nothing...

Pros And Cons Of Placing Indexes On Separate File Groups
Apr 20, 2001We are in the process of replacing our primary production server. In the process of determining how SQL server is going to be structured, it has been suggested that I place all current and new indexes on a separate file group. These filegroups would then reside on a separate shelf on the server. What are the pros and cons of doing this?

Placing Joined Tables On Separate Disks
Apr 7, 2008I've read that if particular tables are frequently queried together through a join then these tables should be placed on different devices on different physical disks.
What does this mean exactly and how would you configure this?
Is this a common practice in high-performance real-world environments (or should it be)?
System Generated Indexes Or Not?
Jun 21, 2001I 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.

Jul 15, 1998I have come across a user that has error 2525 errors on sysobjects tables throughout their SQL 6.5 system. The ids match and I can identify the index. But as they are system tables I cannot drop or rebuild the indexes.
Any ideas please?
The errors have been occuring for some time, so it is not an option to restore. I would like to avoid having to transfer data to and from another SQL Server.
Many Thanks

Rebuilding The System Merge Repl Indexes
Jan 17, 2007Hi,
We have a client that has a large (5Gb) database replicated to 13 subscribers, the publisher is Sql 2005, the subscribers are Sql Express. The publication has as few filtered articles too. I have found that after several months of continuous running Replication Monitor is taking a long time to report history on each subscriber.
Do people tend to rebuild the indexes on the system merge replication tables on production servers, or should the standard replication jobs take care of this?
Thanks for your help

Determining What Are System Objects In Sp_help Or System Tables
Jul 20, 2005Hi,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

Indexes On Related Tables...
Jun 17, 2007Hi,
I have 2 tables with this design: one has ArticleID as primary key and multiple other fields and one has GroupID as primary key and multiple other fields. Each article can belong in multiple groups so I created a new table called articleGroups with only 2 fields: ArticleID and GroupID to show the groups associated with each article. There is a relation between this table and each of the main 2 tables. My question is, in the articleGroup table, does it make any sense to create an Index on ArticleID, GroupID or both? Since the group is needed for each article the Groups will always be queried everytime the article is queried. So, I am not sure if an index is needed?
Thank you,
Regards,
Iulian

How Much Space In A Db Is Available For Allocation To Tables And Indexes?
Nov 19, 2007I was trying to find out how much space is available in a 2000 db for allocation to tables and indexes. I am trying to find the amount of space that has to be used-up before another allocation is automatically made to the database. I looked at sp_spaceused but BOL is rather sketchy at defining what the numbers it returns really mean. Is the "unallocated space" the value I am looking for?
Thanks,
Michael
Should I Create Indexes On Views Or Tables
May 22, 2007I have a pretty large database that has tables that will contain millions of rows of records. I will predominantly be using Views just to select the data. (I will not be performing any updates or inserts). I propose creating indexes on the views. My question is - if I create indexes on my views, do I have to create them on the tables as well? Is it good practice to create indexes on tables by default even if I am not going to be performing select statements directly on my tables but via my indexed views? Any advice is appreciated.
Thanks

Alter Index For All Tables/indexes In A DB
Oct 22, 2007
In SQL Server 2000 one could DBReindex every index that exists in a given database. You can do the same in SQL Server 2005. But how can this be done with the new Alter Index command? It does not allow me to pass in a variable for the object. Any ideas on how to get this done in with Alter Index in 2005? Thanks!
This I can't get to work:
DECLARE
@TableName nvarchar(100)
SET @TableName = 'Account'
USE database;
GO
ALTER INDEX ALL ON @TableName
REBUILD
GO
USE RZTQ5OL02
DECLARE @TableName varchar(255)
DECLARE TableCursor CURSOR FOR
SELECT Name from sys.sysobjects where type = 'U'
OPEN TableCursor
FETCH NEXT FROM TableCursor INTO @TableName
WHILE @@FETCH_STATUS = 0
BEGIN
DBCC DBREINDEX(@TableName,' ',90)
FETCH NEXT FROM TableCursor INTO @TableName
END
CLOSE TableCursor
DEALLOCATE TableCursor
Rebuilding Large Database Tables And Indexes
Jul 7, 2015I have come across a database system which isn't designed to work optimally. It is fairly large (~400GB) and performance of loading and querying is degrading (improper data types, fragmented indexes, non unique clustering key and other problems). So, I have quite a task in front of me, but I am up for the challenge. I figure this is not a unique situation, many of us would have come across this before. I have done this before too, but only for smaller databases, some of the operations here I expect to take a couple of hours or more to complete (depending on load/infrastructure speed etc, I know).
My plan is thus:
+ Take a full backup of the database
+ Set the recovery model of the DB to simple
+ Drop non clustered indexes
+ Drop clustered indexes
+ Remove PKs (wrong data types, too large!)
+ Narrow data types (add new column, update column in batches to old value, rename new column to old column)
+ Add PKs, which will create clustered indexes automatically based on PK ID
+ Create non clustered indexes
+ Run a SHRINKDB (normal operations I would never do this, but this is a special case, ensure log file is truncated to a logical size especially after all those table modifications...)
+ Set the recovery model of the DB to Full
+ Ensure everything works OK or better
Fastest Way To Copy Tables And Their Indexes Between Servers?
Nov 13, 2006The DTS Task Copy Server Objects is PAINFULLY slow.
The Copy Table Wizard is fast but generates an unmanagable DTS and does not bring over the indexes.
Any tips or tricks to copy tables, data and indexes and a reasonable speed?

SQL Server 2014 :: Memory Optimized Tables And Indexes
Feb 18, 2015I'm just beginning to experiment with memory optimised tables.
I have two sets of near identical tables - one set normal, the other set memory optimised with DURABILITY=SCHEMA_ONLY - and am running test queries against these. When I say that the two sets are "near identical", I mean that they are the same except for the primary keys: for the normal tables these are defined as PRIMARY KEY CLUSTERED whereas for the memory-optimed ones they are defined as PRIMARY KEY NONCLUSTERED HASH WITH (BUCKET_COUNT=nnnn) as per the requirements for such tables.
I then run a pair of test queries, again identical but one referencing the normal tables and the other referencing the memory optimised ones.
(The query uses an inner join on three tables with row counts of approx 3m rows, 100000 rows and 5000 rows.)
The query against the normal tables runs noticeably faster than that against the memory optimised ones. To try to find out why, I examined the execution plans. the plan for the memory optimised query suggests that I have a missing index: but of course I can't create this againsty a memory optimised table. Is this a bug or am I missing something? Why the performance between the two should be so different?

Sliding Window Scenario For Shifting Partitions...do All Indexes Need To Be Built On The Staging Tables?
Oct 31, 2007Kimberly Tripp describes a recipe for switching partitions in and out, thru the use of staging tables, when it comes time to "slide the window" on a partitioned table. She says that the clustered index (on staging) must be the same as that chosen for the partitioned table itself but she doesnt discuss whether or not all of the non clustered indexes need to be the same too once the
ALTER TABLE Orders
SWITCH PARTITION 1
TO OrdersOctober2002
and
ALTER TABLE OrdersOctober2004
SWITCH TO Orders PARTITION 24
run. For the data being switched out, I wouldnt want to do anything extra. For the data being switched in, I'd like to understand if she is implying that all other indexes would be built automatically as a result of the 2nd ALTER statement?
