Hi,
We run SQL SERVER 2000 on win2000
I've a question regarding Index on a table.
I've a table (1 milj rows) with a extra index ZINDEX1.
Now lets say I insert 1000 rows in that table.
Now what will happend if I search on these NEW rows in my table.
The Index is not updated.
//Martin
I have written an update, if i see the execution plan of that update, it is showing the Non Clustered index are updated. I am not able to understand the fact, that when there was no change in Leaf level root data how does Non clustered index got updated.

I have a column called "LastModification" in the table, every time the row is update I want to set the value of this column to the current date. So far all I know is that I need to use a trigger and the GetDate() function, but could any body help me with how to set the value of the column to getdate()? thanks for your help.

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 Im doing a simple update in my SP: update users set Name = @Name where id=@userID and password=@password i want to know if a row gets updated. for example if the userID and password dont match then the row will not get updated.so i want some way to tell if a row has been updated. how do i do this?thanks
View 3 Replies View RelatedI have a really strange problem.
I execute this query:
declare @cid int
set @cid = 2003227
select * from sales s, product p where p.product_Id = s.product_Id and customer_id = @cid
select * from sales s, product p where p.product_Id = s.product_Id and customer_id = @cid or @cid = 0
3 Million rows in sales, 120000 in product.
The first does and index seek, the second an index scan.
The execution plan reports that the scan takes 99.87% of the cost, and the seek takes 0.13%
This problem obviously gets worse the bigger the dataset / query /etc.
The reason I query this, is because it never used to take this long to do index scans. Is there something i can change, something i can fix?
Any help would be appreciated.

Hi -
apologies if this is not the right forum for this - I've searched a bit and this seems to be the best fit.
I have the following problem: I want to update records in a table that fit certain criteria. The way the insert logic works make sure that there will always be only one record that fits the criteria and I'd like to get the ID value of that record once the update went through. So here is what I tried:
1 UPDATE Timeslot
2 SET StartTime = @StartTime, EndTime = @EndTime
3 WHERE (ProfessionalID = @ProfessionalID) AND (ProviderLocationID = @ProviderLocationID) AND (RequestID IS NULL) AND (StartTime > @StartTime) AND
4 (EndTime < @EndTime);
5 SELECT SCOPE_IDENTITY()
My hope was that the select scope_identity would return the Timeslot ID of the row that was affected, but it doesn't. How do I get that row?
Thanks!!!

We have a third party process that runs and updated several SQL tables.
Is there any way to find out what tables are being updated and store it in another table?
Guys,
Is there a way to find out when a certain DB object (e.g. Stored procedure) was last modified?
SYSOBJECTS table contains crdate and refdate fields. None of these, however, appear to tell me when when the object was last updated.
Any suggestions?
Thanks a lot
Is there a command that will tell me the number of rows that are updated in a statement. I would like to put this in an Stored Procedure and pass the #rows updated back out.
View 1 Replies View RelatedI have a table written in to sql by the program Wincc flex wich is currently constantly saving data in to it. I want to reed this data back in to Labview and update it’s content on Labview constantly to plot a graph that keeps updating over time.
I have achieved this after some research but my problem is that I need a way of just reading the last row (meaning most recent row, not last row as the bottom one) inserted in to the table written by wincc and saved in sql WITHOUT having to read all the data and selecting for example the higest value of a timestamp column (which is added by wincc) because this would cause too much lag since the table has a lot of elements and I need to constantly read it. One of the main problems is that the data written by wincc is written in a circular buffer, which does delete 20% of the data when it fill’s up and start writing new data in to the free space, so that the temporal order of the data does nothing to do (at least nothing simple) with the index order in the table. Is there anything like a method to save the index of the last row modified in the table so that labview could read it and directly access the most recent recordset in the table just by index specification on a query?
I am writing a generic trigger in VS 2005 that selects records from the inserted table, and updates an audit table. I am, however, unable to retrieve the name of the table that the insert occurred on. I am using the following code to select the records, and obtain the name.. Can anyone offer any alternatives to accomplishing this task? Thanks in advnace for any help you can provide.
