Could Not Find Row In Sysindexes With Index ID
Dec 19, 2005Please help
1. my database can not truncate log and I use this command
BACKUP LOG IMVDB2 WITH NO_LOG
and after that I received result as below
->The log was not truncated because records at the beginning of the log are pending replication. Ensure the Log Reader Agent is running or use sp_repldone to mark transactions as distributed.
2. so I drop all replicate but it's still return same error
so I try to run
DBCC CHECKDB --> but no error meesage
DBCC CHECKALLOC --> but no error meesage
DBCC CHECKTABLE ('sysindexes') --> but no error meesage
but I tried to run
3. DBCC PAGE (IMVDB2, 1, 13015, 3) i recieved
-->Server: Msg 2591, Level 16, State 14, Line 1
Could not find row in sysindexes with index ID 2 for table 'object ID (334220541)'.
DBCC execution completed. If DBCC printed error messages, contact your system administrator.
so what can I do the next to fix this problem, please help[/b]
How Do You Determine An Index Is Unique From Sysindexes?
Mar 17, 2002I need to write a script which will respond differently if a table's index forces uniqueness.
I am using SQL 7.0 and I am using the [sysindexes] table of my database to examine those indexes. I am using the [id] field from the [sysobjects] table for the table I am examining and I am using that [id] field to find like-valued [id] fields in the [sysindexes] table.
My problem is that I can't seem to determine, from an examination of the [sysindexes] table, whether, or not, an index is unique.
When adding an index, and checking the unique property of that index, the values that I get in the [status] field of [sysindexes] are different from the values which are supposed to show, at least according to the sysindexes (T-SQL) entry in SQL Server Books Online.
For instance, I have a table which combines two text fields which comprise the only key on a table. The unique and clustered boxes are checked in the index setup screen. When I look in the [sysindexes] table, the value in the [status] field is 2113554, which is not a value I see in the books online page. According to my books online page, a unique index should have a value of 2 in the [status] field and a clustered index should have a value of 16 in the [status] field. My assumption is that I should see a value of 18 in that [status] field, not 2113554.
I looks like the books online entry might be out-of-date because the field that is labeled [reserved1] in my books online page, is labeled [StatVersion] in my actual [sysindexes] table. That [StatVersion] field looks suspiciously like a Status Version field, possibly indicating that the Status field has undergone some sort of version revision?
Is anyone familiar with this stuff?
Thanks.

SYSINDEXES Index Fail, Error 644
Jan 16, 2006A few days ago a sproc stopped working, only noticed it this morning, when checking information to see what's up I get this:
Server: Msg 644, Level 21, State 1, Procedure uspV2InventoryFetch, Line 83
Could not find the index entry for RID '45574f44523738313834202020202020202020202020202020202020202020' in index page (1:11690152), index ID 2, database 'ASOS'.
Connection Broken
I've treid DBCC CHECKDBing all related tables and everything else. Even tried dbreindexing a couple of them too, everything reports as correct. When I looked further at the problem I spotted "index ID 2" in there, on checking this out in sysindexes it seems that the name field of sysindexes where id = 2 is SYSINDEXES and TSYSINDEXES.
I can't seem to do a DBB DBRECINDEX against a system table.
Any help appreciated.

Index And Primary Key
Dec 9, 2004By defining a numeric field in table as primary key, will the table be indexed on that particular field?
View 14 Replies View RelatedPrimary Key Index
Apr 1, 2004Hi,
I have a table in my SQL 2000 database called utContact, this has a primary called ContactID (int, idenitity), by default this should have a clustered index on it, but when I go to view the indexes on the table it shows the primary key index as non clustered.
How can this be?
SQL server also will not let me change the index to clustered, but I need to as this is causing a lot of table scans in query execution plans.
Any help or advice on this matter would be greatly appreciated.

View 10 Replies View RelatedPrimary Key With Cluster Index
Oct 9, 2007Hi All,
One of my client having 1 million(nearly) records in a table.
I defined the table as below
1) Created table with one col(we can name it as "ID") having IDENTITY
2) Using "alter table", I created CLUSTERED PRIMARY KEY Constraint on Same field (ID)
3) The Primary key having 2 ref with another 2 tables
Now the issue is when we create or define a primary key (With Clustered Option) automatically cluster Index will be created on defined table
As such table having huge data whenever any updation or insertion against that particular table taking huge amount of time, because the cluster Index trying re-paging whole data. Because of re-paging each and every time "Transaction Log also growing in huge" (database is in full recovery mode and client wants in same mode only)
Data partitioning not posible because whole data related and current live data
I tried following options with vain
1) To Clear transaction log I suggested to take regular log backup's
2) I tried to drop cluster index and tried to implement non clustered index
Drop and re-create index is take taking huge amount of time
Even in this process I have to Re_Index remaining Index's also
Pls give me any other solution or suggestion in this regard
with Thanks & Regards

Primary Key With Non-clustered Index
Dec 11, 2007Dear all,
I want to keep certain archive data in certain tables. One such table is currently about 190 GB in size. It has a primary key with clustered index and three non-clustered indexes. The type of queries fired are strictly selects (daily) and inserts (only monthly).
Question: Is it advisable to have a non-clustered index on the primary key column?.....I am finding that the insert performance is getting hurt due to presence of clustered index on such a large table (190 GB).
Let me know your views.

Index Statistics And A Primary Key
Sep 5, 2007Hi
I have a question regarding updating statistics for a primary key.
Background: An update statistics with fullscan is sometimes taking 30 minutes - the table is 80 million rows, with only 4 columns. The table is truncated, and then 80 million rows inserted all in one go.
Now why the update stats is taking that long is another question (I have no idea - any thoughts?), but my question is; Since you can't disable the "not automatically recompute statistics" option for a primary key, and you would think it would be imperitive for the stats to be kept up to date for a PK for inserts.... does this mean the stats would be kept up to date? and an update stat with fullscan isn't required?
Hope someone can help
Thanks

Question On Primary Key, Unique Index

[addr] [varchar](50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,

)WITH (PAD_INDEX = OFF, IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]
But when I tried to input my data like
'abc', '123 abc'
'abc ','123 abc'
SQL server won't recognize 'abc' and 'abc ' is a different value if the last character is a space. Is there a way to make it as a different value? I tried to drop the primary and input the data. When I ran a group by the name column, 'abc' show 2 instead of 1. Seems SQL server is trying to ignore the space at the end too.
I also noticed unique index have the same problem too. Please help.

View 14 Replies View RelatedDistinguish Between The Publisher And The Subscribers
Nov 10, 2006I have a database on SQL Sever 2005 SP1 against which a Publication has been defined and to which many servers (both Workgroup and Express editions - SP1) Subscribe to.
I would like to be able to distinguish between the Publisher and the Subscribers programmatically via T-SQL.
From reading BoL and various forums it appears that the IsPublished, IsMergePublished and IsSubscribed options of the DatabasePropertyEx function should give me this information.
However within all our tested environments, whilst the IsMergePublished option returns expected values. IsPublished and IsSubscribed both return 0 on all servers (the Publisher and Subscribers).
Is this a know issue and how can I rectify the problem or alternatively does anyone know of another method to distinguishing between the Publishers and Subscribers.

How To Keep DataTable's Primary Index In Sync With Database?
May 12, 2008I'm working with a legacy database whose structure I cannot change. I'm building a web-based editor for one of the DB's tables. This table has a Primary Key called "Master_Idx" that is an Identity (autonumber) field.To start, I query the DB and populate a data table which is cached. This is used to "feed" the web form. Any additions, changes, and deletions are reflected in this cached table.The user then has the flexibility to press Save at any time, which ensures that the database is modified accordingly.Here's my question:When new records are added, I assign them a Master_Idx value, the first of which was calculated to be 1 + the Max(Master_Idx) value when the editing session started. But when I insert these records back into the database it's possible that another user might have also been doing similar editing (of different records from the same table), so there's no guarantee that the Master_Idx values in the data table will be identical to those in the DB. When I insert a record from the cached table back into the DB, what technique can I use to check what value was assigned to the Master_Idx? If it's not the same as in the cached table then I need to update it locally in a few places.I hope all of this makes sense but if it doesn't then let me know and I'll explain it in another way.Robert W.
