Hi,
I am trying to drop an index usiong enterprise manager.The process hangs and Enterprise manager is not responding.When I checked the Current activity the process is in sleeping condition.I appreciate if any one can tell me what could be the reason for the process to be hung.
thanks

Here is my code,
1. create table t1 (id int )
2. create unique index u on t1(id)
3. create table t2 (id int constraint f foreign key references t1(id))
4. ALTER TABLE t2 NOCHECK CONSTRAINT ALL
5. ALTER TABLE t1 NOCHECK CONSTRAINT ALL
6. drop index t1.u
I get a FK voilation exception. on line 6.
I was not expecting this, because I am doing 4 & 5
Is dropping the FK is only option?
Actually I am trying to move the unique index to a different file group.

Hi,
I have a table which I am unable to drop the index.
I tried to drop it via the TSQL and GUI interface (Indexes dialog box),
but when I clicked on table refresh, the index still there.
Below is the result after DBCC commands:
1. DBCC checktable(TB_LOCLoan)
Checking TB_LOCLoan
The total number of data pages in this table is 146542.
Table has 1596232 data rows.
Msg 605, Level 21, State 1
Attempt to fetch logical page 462136 in database 'DM_LOCLoan' belongs to object '1744009244',
not to object 'TB_LOCLoan'.
2. DBCC newalloc(DM_LOCLoan)
TABLE: TB_LOCLoan OBJID = 832005995
INDID=0 FIRST=60168 ROOT=642778 DPAGES=146542 SORT=0

objid in sysindexes=832005995 (name = TB_LOCLoan)
TOTAL # of extents = 18393
3. From Error Msg 2525, I have tried the suggested action
use DM_LOCLoan
go
select indid, name, object_name(id)
from sysindexes
where id=832005995
and distribution=463752
go
This query does not return any row.
I am running out of clue of how to proceed! Anybody come across this problem before?
I am very eager to solve this problem as the table is hanging here, I can't even drop it to recreate
and continue data loading.
Thank you.

According to sysindexes, I have a table with a primary key and an index. I'd like to drop the index. However, when I give the drop command, the message "Cannot drop the index 'eventlog._INDEX', because it does not exist in the system catalog." is returned.
I'm not sure what to look for. How do I remove the index?
Hi, all,
I want to re-create an index on a production table.
I got an error 644 "could not find index entry...".
The DBCC CHECKDB and CHECKTABLE gave me this:
Server: Msg 8928, Level 16, State 1, Line 1
Object ID 37575172, index ID 6: Page (1:939782) could not be processed. See other errors for details.
Server: Msg 8939, Level 16, State 1, Line 1
Table error: Object ID 37575172, index ID 6, page (1:939782). Test (*(((int*) &m_reservedB) + i) == 0) failed. Values are 7 and 36.
DBCC results for 'Mfg_DFSFNSF'.
There are 1142314 rows in 326143 pages for object 'Mfg_DFSFNSF'.
CHECKTABLE found 0 allocation errors and 2 consistency errors in table 'Mfg_DFSFNSF' (object ID 37575172).
The table script for the index is like this:
CREATE UNIQUE INDEX [Mfg_ITMDH_MbrIdx] ON [dbo].[Mfg_DFSFNSF]([_ITMDH_OwnRow], [_ITMDH_MbrKey], [RECTYPE]) WITH FILLFACTOR = 70 ON [PRIMARY]
My question is that can I drop it and run above create it to fix the problem in live mode?
I know the other option will be:
DBCC CHECKTABLE (FSDBMR.dbo.Mfg_DFSFNSF, repair_allow_data_loss)
But that has to put the db under single user mode.
Thanks!
I'm trying to drop indexes if they already exist then recreate them as needed, however, I'm getting an error if the index does not exist and I thought that's what the "IF Exists" statement was for.
syntax:
IF EXISTS (SELECT name FROM sysindexes WHERE name = 'idx_acct_no') DROP INDEX accounts.idx_acct_no
go
create index [idx_acct_no] ON [dbo].[accounts] ([acct_no])
go
Error when index does not exist:
Server: Msg 3703, Level 11, State 7, Line 1
Cannot drop the index 'accounts.idx_acct_no', because it does not exist in the system catalog.
Is there anyway to not get this error?
Hi all,
I come from MySQL.
In sqlserverce
I'm looking for an equivalent command..to
"DROP INDEX IF EXISTS inventory.idxItems"
or somthing similar so that I do not get an error or crash the C# app when I try to drop a nonexisting index..
also for droping a table.
If I rebuild the clustered index using this option (Drop Existing) without specifying the Fill Factor, would it it retain the original Fill Factor?
Thank you

Is there anyway to drop an index at the partition level in SQL 2005 ?There is a way to rebuild at the partition level (assuming this creates)i.e.: alter index ALL on dbo.LP_CQ rebuild partition = 229 ;I want to:1. Drop index(es) at partition level (partitioned by period value (1..400)).2. bulk copy data in (can be 1 or more periods per day).3. Rebuild at Partition level.Thx
View 1 Replies View RelatedI just tried to backup a database I recently deployed to to SQL Server 2005 box, and got the following error:
The backup of full-text catalog 'myCatalog' is not permitted because it is not online. Check errorlog file for the reason that full-text catalog became offline and bring it online.
Or BACKUP can be performed by using the FILEGROUP or FILE clauses to restrict the selection to include only online data.
I don't need the index so I tried to drop it with both:
DROP fulltext catalog 'myCatalog'
and
DROP catalog 'myCatalog'
but both give me a syntax error.
How can I get rid of this index so I can backup my database?

SQL SERVER 2000System let's you alter the system tables and add indexes. However, it won'tlet you drop the index afterward.Anybody know how to drop an index on a system table?Thanks,Kevin
View 4 Replies View RelatedI have a non-clustered index on a table. If I rebuild or reorganize it in SQL 2005, the total fragmentation percent reported by properties/fragmentation on the index stays at 33%.
Why doesn't the fragmentation go to 0% ?
If I totally drop/create the index, starts even higher, but beorg or rebuild simply goes to 33%. This even if using with use temp db for sort option.
I need a way to push create index statements drop to the subscribers. If I can use replication to distribute index creation that would be great. We don't allow our clients to make any schema changes directly. We are using transaction and merge replication.
View 4 Replies View Relatedhello everyone,we dropped the clustered & nonclustered indeces on a table, thenrebuilt them. logical fragmentation is near zero, but extentfragmentation is about 40%. how can this be if the indeces are brandnew?
View 2 Replies View RelatedWe are running MS RS and SQL Server 2000 SP3.
We have one LEDGER, where all the daily activities are stored. The LEDGER table has 4 indexes (1 clustered and 3 non-clustered). To get AR we use this table.
Well problem is some times in 1-2 months, any simple AR query takes a long time and every other client gets slow response (queries are very slow or sometimes block).
If we DROP any index on LEDGER table and again put it back (RECREATE), all our queries work fine and faster. This goes on till 1-2 months, till we see the same issue again.
This is a classic case happened today. Queries were running fine till morning 8 AM. We upload some 50 thousand records to Ledger table (Data Conversion). Well after 30 mins, all simple AR queries started taking a long time. We DROPPED an index in LEDGER table and everything was faster....Just to be same we added back the same index again.......everything is Faster.....
What is this. ....is it our QUERY, index or huge Transactions or no free space ???
We are scheduled to run SP4, next week. But is there any solution in the mean time on what is this?
Also is they any way to KILL all SQL server processes that take more than a mins. We just don't want ALL our client to Slow down because of one query????
Thanks,
After the incremental process and full process, SSAS doesn't drop the index files #.xxx.fact.map and #.xxx.fact.map.hdr in the file.0.dim folder. We now have all the versions from 3 to 5000 sitting in the folder. The DBA team only found this when the disk is running out of space recently.
We've already check the account running the SSAS has local admin to the server.
Is there any config setting that might cause this issue? If not, what could it be causing this issue.
What is the impact on the users to drop an index on a table while in use? I will recreate the index afterwards. The table is used constantly by a three of processes/users at all times.
View 3 Replies View RelatedI am new to mssql server. There is a table on one of my databases that occupies a lot of space. And the space usage is as follows: (all values in KB)
reserved: 42329064
data: 16272288
index: 26050032
unused: 6744
This table takes up almost 80% of my database size, and the information is this table just captures the time spent by a user on the website(not very critical data)
I would like to know how to delete the entire index (which is what is occupying most space) to free up disk space. the index is a clustered index.

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.
Dear All.
We had Teradata 4700 SMP. We have moved data from TD to MS_SQL SERVER 2003. records are 19.65 Millions.
table is >> Order_Dtl
Columns are:-
Client_ID varchar 10
Order_ID varchar 50
Order_Sub_ID decimal
.....
...
..
.
Pk is (ClientID+OrderId+OrderSubID)
Web Base application or PDA devices use to initiate the order from all over the country. The issue is this table is not Partioned but good HP with 30 GB RAM is installed. this is main table that receive 18,0000 hits or more. All brokers and users are using this table to see the status of their order.
The always search by OrderID, or ClientID or order_SubNo, or enter any two like (Client_ID+Order_Sub_ID) or any combination.
Query takes to much time when ever server receive more querys. some orther indexes are also created on the same table like (OrderDate, OrdCreate Date and Status)
My Question are:-
Q1. IF Person "A" query to DB on Client_ID, then what Index will use ? (If any one do Query on any two combination like Client_ID+Order_ID, So what index will be uesd.? How does MS-SQL SERVER deal with these kind of issues.?
Q2. If i create 3 more indexes on ClientID, ORderID and OrdersubID. will this improve the performance of query.if person "A" search record on orderNo so what index will be used. (Mind it their would be 3 seprate indexes for Each PK columns) and composite-Clustered index is also available.?
Q3. I want to check what indexes has been used? on what search?
Q4. How can i check what table was populated when, or last date of update (DML)?
My Limitation is i Dont Create a Partioned table. I dont have permission to do it.
In Teradata we had more than 4 tb record of CRM data with no issue. i am not new baby in db line but not expert in sql server 2003.
I am thank u to all who read or reply.

Hi,
I'm running a merge replication on a sql2k machine to 6 sql2k subscribers.
Since a few day's only one of the merge agents fail's with the following error:
The merge process could not retrieve generation information at the 'Subscriber'.
The index entry for row ID was not found in index ID 3, of table 357576312, in database 'PBB006'.
All DBCC CHECKDB command's return 0 errors :confused:
I'm not sure if the table that's referred to in the message is on the distribution side or the subscribers side? A select * from sysobjects where id=357576312 gives different results on both sides . .
Any ideas as to what is causing this error?
Hi everyone,
When we create a clustered index firstly, and then is it advantageous to create another index which is nonclustered ??
In my opinion, yes it is. Because, since we use clustered index first, our rows are sorted and so while using nonclustered index on this data file, finding adress of the record on this sorted data is really easier than finding adress of the record on unsorted data, is not it ??
Thanks
I have a clustered index that consists of 3 int columns in this order: DateKey, LocationKey, ItemKey (there are many other columns in this data warehouse table such as quantities, prices, etc.).
Now I want to add a non-clustered index on just one of the other columns, say LocationKey, like this:
CREATE INDEX IX_test on TableName (LocationKey)
I understand that the clustered index keys will also be added as key columns to any NC indexes. So, in this case the NC index will also get the other two columns from the clustered index added as key columns. But, in what order will they be added?
Will the resulting index keys on this new NC index effectively be:
LocationKey, DateKey, ItemKey
OR
LocationKey, ItemKey, DateKey
Do the clustering keys get added to a NC index in the same order as they are defined in the clustered index?
Quick question about the primary purpose of Full Text Index vs. Clustered Index.
The Full Text Index has the purpose of being accessible outside of the database so users can query the tables and columns it needs while being linked to other databases and tables within the SQL Server instance.
Is the Full Text Index similar to the global variable in programming where the scope lies outside of the tables and database itself?
I understand the clustered index is created for each table and most likely accessed within the user schema who have access to the database.
Is this correct?
I am kind of confused on why you would use full text index as opposed to clustered index.
Thank you

Hi All,
I 'm working to improve some sql performance.
One of the major syntax inside the SELECT statment is ..
WHERE FIELDA IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='A') AND
WHERE FIELDB IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='B') AND
WHERE FIELDC IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='C') AND
WHERE FIELDD IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='D') AND
WHERE FIELDE IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='E') AND
WHERE FIELDF IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='F')
(It's to compare the field content with some user input parameter inside a parameter table... )
I think properly is that the SELECT ... IN is causing much slowness in the sql statement. I have indexed FIELDA , FIELDB, FILEDC etc and those PARAVALUE and PARATYPE in the PARATABLE table. But perfromance is still slow and execution takes >20 seconds for 200000 rows of records.
Do any one know if still any chance to improvide the performance like this?
Much Thanks,
Andy
I'm trying to find whether there is a dmv or system view that can help me see the last time an index was rebuilt or created. Assuming I rebuilt an index using tsql commands (not a job with a history), is there a way to find out the last time that index was rebuilt?
Thanks much.
Hi folks.
Here i have small problem in transactions.I don't know how it is happaning.
Up to my knowldge if you start a transaction in side the transaction if you have DML statements
Those statements only will be effected by rollback or commit but in MS SQL SERVER 7.0 and 6.5
It is rolling back all the commands including DDL witch it shouldn't please let me know on that
If any one can help this please tell me ...........Please............
For Example
begin transaction t1
create table t1
drop table t2
then execute bellow statements
select * from t1
this query gives you table with out data
select * from t2
you will recieve an error that there is no object
but if you rollback
T1 willn't be there in the database
droped table t2 will come back please explain how it can happand.....................
