i hav a table, Test1, with a clustered index and two non clustered index defined on it.
When i use sp_help Test1, the CI and non clustered index are listed along with the column names.
when i query the sysindex table (for id = object_id(Test1))
i can see entries like _WA_Sys_<<ColumnName>>_3D5EEB29.
what are these entries? are they indexes? if yes, how these entries are created and what is the significance of these entries.
Pl discuss.
Thanks.
hi all,i was using the system tables namely sysindexes and sysobjects in sql server 2000. But now sql server 2005 is using instead of sql server 2000. Since am using sysindexes and sysobjects, too much time is taking for the execution in sql server 2005. So I need to change the query suitable for sql server 2005.I have read in msdn that the system tables are replaced with corresponding catalog views in sql server 2005. The catelog view for sysobjects is sys.objects. plz check the link http://technet.microsoft.com/en-us/library/ms187997.aspxCould anyone please tell me how to replace the sysindexes and sysobjects in the query without rewriting the query too much. If I can replacesysobjects with just sys.objects, then it will be very helpful. Is it possible? And what about sysindexes. Any help anyone could give would be greatly appreciated!
View 8 Replies View RelatedWhen you have a table with no indexes you can see the table name in sysindexes and the relevant data in the rest of the fields with an indid of 0. I understand this bit.....but when you have created an index and then you delete it again.... the row in sysindexes just has the tablename and no other data?
Weird or by design?
Cheers timmers
I have read at this location--
http://www.swynk.com/friends/achigrik/RowCount.asp
that it is better to use sysindexes to get a rowcount.
Can I be assured that this is always up-to-date?
How can I use sysindexes table to determine the indexes, tables being indexed, and the columns to which the indexes belong.
Thanks
It seems my sysindexes table is inaccurate on a nonclustered index. In my case the rowcount (rows and rowcnt) do not match the actual rowcount of the table. The command UPDATE STATISTICS doesn't change the rows or rowcount, adding 'FULSLCAN' won't budge rowcount either.
After I did a dbcc reindex, the number of rows matched, however, upon adding rows in the table both rows and rowcount are out of sync again.
It's a fairly straightforward table, no triggers, no computed fields, only integer, datetime, varchar and bigint columns. There's a clustered index on a bigint column and a nonclustered index on a integer column.
dbcc show_statistics show that the nonclustered index is updated and it's rows and rows sampled match the number of rows in the table (not in the sysindexes-table).
I'd like to know if I'm chasing ghosts here or if there's something very wrong here. What could be causing the counts being inaccurate? Anyone who could shed some light?

I am trying to attach a database that was created on another server. I believe the database was created using SQL Server Management Studio Express 2005. Now, I have successfully attached the database in my development environment, which is using SQL Server Management Studio Express 2005.
However, when I tried to attach the database onto our production server, which is SQL Server 2000 I received the error:
Error 602:Could not find row in sysindexes for database ID 18, object ID 1, index ID 1. Run DBCC CheckTable on sysindexes.
In my development environment, I ran DBCC CheckDB on the source database and no errors are returned.
I aslo checked the compatibility level under the database properties and it shows: Sql Server 2000 (80)
So, this should not be a version incompatibility issue. What is causing the attach to fail on SQL Server 2000?
Thanks for any help.
Does nayone know how to identify the tables fields from the keys col. in the

Does anyone know what status 8388704 represents? The table in question is a heap. There are two of these on the table, and they don't show up in EM but are listed in sp_help. They also have weird names associated with their entries in sysindexes "_WA_Sys_CUST_PO_NBR_0F975522" and "_WA_Sys_ORD_STUS_CODE_0F975522"... I've searched everywhere... HELP!

Can anyone explain why when I look at table using enterprise manager, highlight a table, all tasks, maanage indexes why only 1 index appears and when I look at the same table in sysindexes is says that there are 8 indexes.
This is the sql code I executed:

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

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]
I have some errors in my DB, we do have a backup plan in place, but the person who put it in place is no longer here. It's all automated and running, the problem is , we do A LOT of transactions a day, and the error has been in the db since 9/20(2.5 weeks) when someone shut the power off accidentally. So i'm reluctant to do a backup, mainly since i have NO idea how to do one, we do full and incremental, full on weekend, incremental weeknights.
below is the biggest problem SYSINDEXES :(. a few other tables had problems but DBCC with repair_allow_data_loss has fixed those with 'hardly' any data loss. What can I do here?
THanks in advance

I 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.
Ken

WHen researching an index name problem, I found duplicate index names in sysindexes, referencing the same table. I notice that one of the indexes has a status = 2097154 and a indid of 2 while the other has a status of 0 and a indid of 0. I believe these are duplicates. Anybody have an idea if these really are and what the status and indid fields mean?

SQL Server 2005 9.0.3161 on Win 2k3 R2
I receive the following error:
"Error: 8624, Severity: 16, State: 1 Internal Query Processor Error: The query processor could not produce a query plan. For more information, contact Customer Support Services."
I have traced this to an insert statement that executes as part of a stored procedure.
INSERT INTO ledger (journal__id, account__id,account_recv_info__id,amount)
VALUES (@journal_id, @acct_id, @acct_recv_id, @amount)
There is also an auto-increment column called id. There are FK contraints on all of the columns ending in "__id". I have found that if I remove the contraint on account__id the procedure will execute without error. None of the other constraints seem to make a difference. Of course I don't want to remove this key because it is important to the database integrity and should not be causing problems, but apparently it confuses the optimizer.
Also, the strange thing is that I can get the procedure to execute without error when I run it directly through management studio, but I receive the error when executing from .NET code or anything using ODBC (Access).

how do I get the variables in the cursor, set statement, to NOT update the temp table with the value of the variable ? I want it to pull a date, not the column name stored in the variable...
create table #temptable (columname varchar(150), columnheader varchar(150), earliestdate varchar(120), mostrecentdate varchar(120))
insert into #temptable
SELECT ColumnName, headername, '', '' FROM eddsdbo.[ArtifactViewField] WHERE ItemListType = 'DateTime' AND ArtifactTypeID = 10
--column name
declare @cname varchar(30)

-- The 3rd query uses an incorrect column name in a sub-query and succeeds but rows are incorrectly qualified. This is very DANGEROUS!!!
-- The issue exists is in 2008 R2, 2012 and 2014 and is "By Design"
set nocount on
go
if object_id('tempdb.dbo.#t1') IS NOT NULL drop table #t1
if object_id('tempdb.dbo
[code]....
This succeeds when the invalid column name is a valid column name in the outer query. So in this situation the sub-query would fail when run by itself but succeed with an incorrectly applied filter when run as a sub-query. The danger here is that if a SQL Server user runs DML in a production database with such a sub-query which then the results are likely not the expected results with potentially unintended actions applied against the data. how many SQL Server users have had incorrectly applied DML or incorrect query results and don't even know it....?

I run it in query analyser and works fine, but when I try to run in Reporting Services, Visual studio stops responding and the cpu reaches 100 %.
I realize that when I cut off the if clauses, then it works at Reporting services.

Why the query works in query analyser and doesn't work in Reporting Service ?
