hello,
I'm running my user database on a SQL Server 2000. I would like to extract all the indexes from the database and I was wondering, how can i do that. I dont see an option for doing this.
Appreciated If someone out there help me please.
Thanks in advance.
I'm working to improve performance on a database I've inherited, and there are several thousand indexes. I've got a list of ones which should definitely exist within the database, and I'm looking to strip out all the others and start fresh, though this list is still quite large (1000 or so).
Is there a way I can remove all the indexes that are not in my list without too much trouble? I.e. without having to manually go through them all individually. The list is currently in a csv file.
I'm looking to either automate the removal of indexes not in the list, or possibly to generate the Create statements for the indexes on the list and simply remove all indexes and then run these statements.
As an aside, when trying to list all indexes in the database, I've found various scripts to do this, but found they all seem to produce differing results. What is the best script to list all indexes?
So I'm reading http://www.sql-server-performance.com/tips/clustered_indexes_p2.aspx and I come across this:
When selecting a column to base your clustered index on, try to avoid columns that are frequently updated. Every time that a column used for a clustered index is modified, all of the non-clustered indexes must also be updated, creating additional overhead. [6.5, 7.0, 2000, 2005] Updated 3-5-2004
Does this mean if I have say a table called Item with a clustered index on a column in it called itemaddeddate, and several non-clustered indexes associated with that table, that if a record gets modified and it's itemaddeddate value changes, that ALL my indexes on that table will get rebuilt? Or is it referring to the table structure changing?
If so does this "pseudocode" example also cause this to occur:
sqlstring="select * from item where itemid=12345"
rs.open sqlstring, etc, etc, etc
rs.Fields("ItemName")="My New Item Name"
rs.Fields("ItemPrice")=1.00
rs.Update
Note I didn't explicitly change the value of rs.fields("ItemAddedDate")...does rs.Fields("ItemAddedDate")=rs.Fields("ItemAddedDate") occur implicitly, which would force the rebuild of all the non-clustered indexes?
I have a requirement to only rebuild the Clustered Indexes in the table ignoring the non clustered indexes as those are taken care of by the Clustered indexes.
In order to do that, I have taken the records based on the fragmentation %.
But unable to come up with a logic to only consider rebuilding the clustered indexes in the table.
create table #fragmentation
(
FragIndexId BigInt Identity(1,1),
--IDENTITY(int, 1, 1) AS FragIndexId,
DBNAME nvarchar(4000),
TableName nvarchar(4000),
[Code] ....
What is the difference please?

On extracting ddl's for each object on a separate file in SQL Server?
Something like ddl's for:
procedure1.sql, procedure2.sql.....so on procedure100.sql
onto a file server.
Does SQL Server has any API's like Oracle's dbms_metadata?
Or can we use SQL enterprise manager to do this job?
Thanks, Madhavi.
I am trying to extract just the session id from some iislogs, and was curious the best way to go about doing this. The session ids will all be like "ASP.NET_SessionId=1wtdqn241f0ews55n5hsipib" with 42 chars in length, however the sessionid can be anywhere in the column, sometimes by itself, sometimes at the beginning and sometimes near the end. I guess the best way to do this is search for %ASP.NET_% but im not sure how to pull just the sessionid out.
does anyone know how I should approach this or where this topic has been brought up in the forums so I could get an idea. I tried searching by instr and sessionid and few others.
Thanks

The situation is I need info from a certain SharePoint site that is in a sql database. The problem is The SharePoint site currently contains data from 9 different projects, all using the same database. The database is a complex setup and it would not be an easy operation to extract the special information alone. The database is run with Microsoft SQL and is comprised of 4 separate databases. 3 databases organize the data (500+mb of data total) and 1 stores the data for all the sites (12.5+GB and increasing at a rate of 100-300mb per day).
How can I get the special data I need from this setup???
Please help

Hey guys
Im pretty new to SQL so i was wondering if you might be able to give me a hand with something.
I have 2 tables, clients + orders. Each table contains a column called custID which contains the client code, each order creates a new record in the orders table so the orders table contains many more records than the clients table.
I am trying to find out what clients have not placed orders at all, but i can't wrap my head around it, i can obviously work out who HAS, but i need to find out who HASN'T.
Any help would be really appreciated.

I am trying to populate two fields in my table with the first 6 characters in an existing field with the following command:
SELECT dimension_elist,
SUBSTRING(dimension_elist FROM 1 FOR 6)
AS BU_Number
SUBSTRING(dimension_jde_pl FROM 1 FOR 6)
AS Acct_Number
FROM JDE_Import
The result is an error:
Server: Msg 156, Level 15, State 1, Line 2
Incorrect syntax near the keyword 'FROM'.
I am fairly new to SQL so I am probably missing something basic.
Does anyone have any thoughts?
Hi,
I have two tables - a stock table and a transaction table. The stock table is called stock and the transaction table is called trans. The table make a point of sale database. Both table have a joining field called prod_no.
I want to extract the stock line by querying stock.prod_no that are not present in the trans table for a period of time specified.
Basically, I want to find dead stock lines that have not been sold and, therefore, are not in the transaction table but that have a stock figure. I have to enter in a start and end date paramater using the ddate field in the trans table. I have looked at left, right and outer joins but with no luck and don't even know if this is the correct query type to use.
any help would be much appreciated,

I'm analyzing the problem of extracting data from sql server 6.5 in order to load it into oracle.
I already know about the bcp tool, but I'd like to know if you would consider any other approach based on SSIS, or any other tool like SQL Load.
regards, and thanks in advance for your help.
We have an identifier of who has performed an ection which populates a table with their email address in the format firstname.surname@domain. I am looknig for some code to split out the first name and surname (and, if possible, capitalise both) so uor audit report can show the actual name instead of the email address.
Has anyone encountered this issue previously and know a solution?
Many thanks in anticipation.
Good Afternoon,
I have been asked to extract data from a Transbase database. I'd like to do this by using SSIS. Has anyone worked with Transbase? If so, have you been successful in extracting data from it? What procedure did you use?
Thanks much for your help.
