WE have a database named DM on a test system and production system. All the indexes got lost in the test system somehow. Is there a way i can copy the indexes from the production system to the test system like I know you can with data?
Thanks

I set up replication on our servers at work to streamline some procedures we run daily/weekly on them. This copies around 15 articles from two databases on the "Master" server to another server used for execution purposes. For the most part it was a pretty straight forward task and it seemed to work nicely; but I realised after some investigation that the non-clustered indexes weren't copying over to the child server.
I set the non-clustered indexes property in the properties of the publishing articles to "True" and generated a new snapshot, this seemed to work, but I've come into work this morning to find the property has reset to "False" and I have no indexes on the table again. Why is this happening and is there any way I can resolve the matter so the indexes are copied over concurrently?
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?

Hi, I have been having fun and games for well over a week now trying to get an xml file copied into an sql file, but still have no joy. I and using the bulk copy to do this and think I am close to solving it but just need a final push in the write direction.
In green below is the full source code, I think that the trouble is with the try statement part here:
Try
bulk.WriteToServer(xd)
This comes up with the error :
Unable to cast object of type 'System.Xml.XmlDocument' to type 'System.Data.IDataReader'
Basically how do I get the XML data into a reader (or IDataReader) format so that the writetoserver command can interpret it
I would be so greatful if someone could help resolve this it is becoming increasingly more frustrating

I've got two DBs in the same SQL instance. They are named TST and PRD. I am using 2.0 so there are many ASP generated tables also. Every once in a while I want to refresh data from PRD to TST. But I don't want to copy the data from ASP tables.What is the easiest way to do so?
View 6 Replies View RelatedHi,
I'm trying to insert one value (an order) into the table Order and (via a for-loop) all the products in that order in the table Product, hence, one order can have multiple products (and must have at least one). I have an automatically increased value for the OrderID as the primary key for Order, and I have a foreign key named OrderID in the Product table. So far, I _think_ everything's logically correct.
However, I don't understand how to retrieve the OrderID to be able to insert it in the Product table upon insertion. I guess this is done all the time, but the only solution I can think of is to make a new SQL Command, asking for the just created OrderID to use it in the SQL Command for the products' for-loop. I'm sure that's a bad idea. :-)
Can I use relationships or so to make this automatically updated (that is, to have the Product table "check for" the OrderID and insert the OrderID upon insertion of the Product row(s))?
I hope this is clear to you. Thanks in advance for all help!

Hello List,
Folks, I need a help here. We are running our production database on SQL Server 7.0. We are in a process of switching the production database server to another server hardware. I was wondering, How can we copy the Logins/Passwords from my old server to the new one. Well this is very important to have all the old logins and passwords on the new server to have anybody login to it. I know, Doing Export will copy the logins. But would it allow the same old password to be on the new server?
Please help me here.
I have a SQL Table called Consumers that contains 495,037 records.
The record size is about 350 bytes and it has one field that is a varchar (255). I am using DTS to copy this file from SQL (7.0) to Access (97). Last week this file had about 216,000 records and the DTS Process worked okay. Today, it has 495,037 records and the DTS Process appears to lose some records (about 26,000) during the copy. In the DTS Package the SQL query is just a straight SELECT statement with no WHERE condition.
During the DTS Process the SQL Consumers Table is being copied to and Access Table. The error I am getting during the DTS Process is "Error at Destination for Row # 468608".
When I open the Access Table it shows 468,608 as the actual number of rows in the Access Table and shows ConsumerID 675820 (primary key, identity field) for this particular record.
When I link to the SQL Table via Access the Record # 468,608 shows ConsumerID 643852 and the last record shows Record # 495,037 and ConsumerID 675820.
This tells me that some records are not being copied over during the DTS Process. The last record on the SQL Table is on the Access Table. So there are probably 26,429 (495,037 on SQL Table minus 468,608 on Access Table) that are not on the Access Table.
The DTS Select Query does not have a Where Condition. Do you think some records are being lost because of the size of the SQL Table?
There is an Advance Tab on the DTS Properties Page; there are some
options like 'Insert Commit Size', Fetch Buffer Size', 'Use Fast Load', 'Keep NULLS', and 'Check Constraints' that I
need to take a further look at. Have you used any of these options and do you think any particular one may help
my problem?
There is also and 'Exception File Name' option. I will give this a try next week to see if it will write the problem
records to disk.
Thanks for your help, Kevin

Hello,
This may seem like an easy question, but I have a DTS package that I need to copy to another SQL server. Is this done easily? Can it be done (i think so?).
Thanks in advance,

I have an 8 GB SQL 6.5 database that I need to move to another server. I know I can create the devices and the database on the new server exactly as they were created on the old server then replace the new DAT files with the old (after shuting down SQL Server). The issue I am running into is that the sort order and character sets on the two servers are different. Will this have an effect if I copy the DAT files? Am I better off using BCP? I'd hate to use BCP because of the time that it will take to move the files.
Thanks for you help
Does anyone know how to move or copy DTS Package?
That I need to do:

Any help greatly appreciated

Hi, I'm pretty new to SQL so am still learning the syntax etc.
I have 2 tables, one called Railways and another called Sheet1$ (an import from Excel).
In Railways, I have 5 Fields:
ID
First_Name
Last_Name
File
Full_Name
At the moment, all are populated with data (300 records) but Full_Name is showing values of <NULL>.
I want to populate Full_Name with the Data in Sheet1$ which has the field Full_Name (which is populated with the data I need)
What is the query I need to run to get SQL to copy the data from Sheet1$ (Full_Name) into Railways (Full_Name) - replacing all of the <NULL> values?
I've tried using the import wizard but without success.
Thanks in advance.

I was trying to find the fastest way to COPY a 50G DB from our production server to our test server. I was testing this on our test server and had a simple question.
Attach/Detach is out since I can only move not copy a DB using this method.
export/import, bcp and DTS take too long and are not indented for this anyways.
so, I was left with Backup and restore. so, I tried that on two different test servers. Took very long. so, I decided to be brave and try the following.
1. Take DB1 that's running on server1 OFFLINE
2. Manually copy all datafiles and logfiles from Server1 to server2.
3. Attach DB1 on server2.
It came up great. No complaints whatsoever. So basically, it's the same as attach/detach but instead of detaching the DB I took the Db offline and copied the files over. So my question...
Is this supported?
Any chance of corruption on either of the servers?
If a DB is offline, is copying datafiles and logfiles supported (I am bit worried if I might corrupt data in production).
Do people use this method to COPY databases or do they stick with BACKUP and RESTORE?
PS: Are there any other ways to do this?
Thanks so much.
just wondering how can i script out so that i can copy a table from a database but not the data itself..

Hi all, I'm in the process of cleaning up a very VERY poorly implemented system. One of the problems I'm tackling consists of :
1 - Database A
2 - Database B (different schema than A)
3 - A task which regularly polls A, checks for updated/new records and inserts them (with some transformation) into B
As you can imagine, the overhead of the polling is killing the system. What I want to know is :
What is the best way for A to notify B whenever there are changes to a particular table on A ?
I'm running 2000 but we will most probably upgrade to 2005.
thanks in advance to everybody

I am assuming there is some functionality to copy and paste a table in sql server..however I am not seeing where I can do this what I want to do is this:
create table1 as select * from table 2;
Please let me know how I can create a new table as a replica of an existing table. Thanks so much!
