How Do I Copy The Index Statistics To A Development Database Server Without Data.

Hi,
Can anyone please explain the proper precedure for copying a SQL Express database between two instances?
I am accessing the database without problems from a local web application. And I want to copy the database to a SQL Express instance on another server, running the same web application.
I run into two problems every time I copy:
1) Orphaned users. I have to drop the database users and the re-map the server users to database users.
2) The full-text indexes are not available after copy, so I have to drop and re-create the indexes and the catalog.
And I suspect there's an easier way..
Regards,
Jens Erik
Is there any way to move a db with full-text indexes from one physical machine to another without having to drop catalog/indexes and the re-create them?
Cheers!

What are some ways to analyze index coverage and usage? I have a 18 GB database, half is data, other half is indexes and I want to cut down that number as much as I can without affecting performance. Thanks

I have been monitoring some indexes on a table with a lot of inserts, no updates and no deletes. I was wanting to determine when to update the statistics on the index. Does anyone know what would be a good target range for the density when you run the dbcc show_statistics?
View 1 Replies View RelatedI was wondering how often you should reindex. By looking at dbcc showcontig and statistics I see that I am heavily fragmented and scan density is between 10-30% on my important indexes. I'm thinking of scheduling this to be done nightly. nay help is much appreciated.

Hello,
I am trying to refresh a test database with data from a production database. Both database structures are identical, e.g. constraints, stored procs, PK, etc. I am trying to create a package in SSIS that accomplishes this task and I am having extensive problems. The import export wizard is out of the question because the constaints are not carried over, plus when I try to refresh the data using the import export wizard, it fails on 1 specific table because of a column in that table named "Error code". I think "Error code" is a micrsoft keyword, so it fails on this column. Does anyone know a workaround that I can do to accomplish this simple task, that could be completed in minutes using DTS. I understand that SSIS is not as straight forward as DTS, but this task is something that DBA's do on a regular basis and therefore should not be this difficult.
Any help would be appreciated,

At managing index SQL Server 6.5, there is distribution button. I have a database on production server, one of the table has 20 indexes. When I press the Distribution button, it reveals that most of the indexes have very poor selection of index, from 30% to 99%. There are 6 of them are very good. Based on this statistics, do you think I should remove these indexes? As the book says, if the statistics is higher than 5%, the optimizer will not use index but do a table scan. Removing those index should not affect the performance, is that right?
Your suggestion is very appreciated.
Hi
I have a question regarding updating statistics for a primary key.
Background: An update statistics with fullscan is sometimes taking 30 minutes - the table is 80 million rows, with only 4 columns. The table is truncated, and then 80 million rows inserted all in one go.
Now why the update stats is taking that long is another question (I have no idea - any thoughts?), but my question is; Since you can't disable the "not automatically recompute statistics" option for a primary key, and you would think it would be imperitive for the stats to be kept up to date for a PK for inserts.... does this mean the stats would be kept up to date? and an update stat with fullscan isn't required?
Hope someone can help
Thanks
James
I ran the DBCC SHOW_STATISTICS command for all of my indexes; I was told that high density numbers are bad, low numbers good. I have some questions about my results, though; I'm not sure how to interpret them.
Of 48 indexes, 14 have a density of 0. Does this mean that the indexes are not selective enough? Does it mean they're garbage and I should toss them?
6 have a density of NULL. They are all primary keys. I suppose this just means that they're never used because these tables are rarely queried. Would this assumption be correct?
13 have a density of 1. I have no idea what this means.
The others have densities ranging from 0.01210491 to 0.5841165. I was told that the lower this number is, the more selective and thus more useful an index is. I think 0.5841165 is too high a number. Would this be correct?
Thanks in advance.
Is it neccessary to schedule a update statistics on index in sql server 2005 on daily basis
Is it neccessary to schedule a rebuild index on index in sql server 2005 on daily basis
Ok, here is my dilemma
I have an application that has many sites. Each site has it's own database. The databases have common tables (ie the name and fields are the same) What I want to be able to do is when creating a new database, I want to be able to copy certain common table data from one database to another. I have run into an error because the table have an IDENTITY so this is not working
INSERT INTO Containers SELECT * FROM ADMS2_Indian_Point.dbo.Containers
I also tried
USE ADMS2_RSCS
GO
SET IDENTITY_INSERT Containers ON
GO
INSERT INTO Containers SELECT * FROM ADMS2_Indian_Point.dbo.Containers
GO
SET IDENTITY_INSERT Containers OFF
GO
I got an error saying that I need to have a column list. I am trying to use this for any tables, so my question is this..
Is there any way to get around using a column list or is there a way to dynamically create the column list?
Or, Is there a better way that I should be doing this?
Please keep in mind I am not a dba and everything I have learned about SQL is from my good pal Google :)
Thanks for any help
Hello!
Is there any way to determine index usage statistics for a given table?
For examle, I have a table, with three indices. I need to know how many times each index was used. Is it possible?
And second part of question: I need to know, which user overloads my base with their giantic queries. Is there any way to determine, how many system resources each of user's sessions uses?
MS SQL Server 2000 Enterprise Edition.
Thank you!
We have a 20 GB database and reorganize indexes and update statistics maintainance takes about 4 hours and the log files grows out of control what is a serious problem since it can not be truncated (database mirroring).

Hi ..
Please advice whether i have to do update statistics along with Index rebuild (online /off line)
Thanks in advance
I have an index that shows distribution statistics of 98.20%, which is very poor. I set show query plan and show statis I/O on. This table has 1113675 rows of data.
*************
select orderID, custId, intertcsi from tblorders
where intertcsi = '2815'
STEP 1
The type of query is SELECT
FROM TABLE
tblorders
Nested iteration
Index : indxInterTCSI
orderID custId intertcsi
----------- ----------- ---------
1015245 1011313 2815
2556392 2556392 2815
....
Table: tblOrders scan count 1, logical reads: 104, physical reads: 58, read ahead reads: 0
***************
Then I use the same select statement to force a table scan:
select orderID, custId, intertcsi from tblorders (index=0)
where intertcsi = '2815'
STEP 1
The type of query is SELECT
FROM TABLE
tblorders
Nested iteration
Table Scan
orderID custId intertcsi
----------- ----------- ---------
60472 61084 2815
102184 102333 2815
...
Table: tblOrders scan count 1, logical reads: 110795, physical reads: 6891, read ahead reads: 103980
When the index is not provided, the logical reads and physical reads increased dramatically. Does this tell me that I should keep that index though it is a poor selection? Is that because a huge table like this make the optimizer use the index. The query without using index takes longer time to run.
Any idea or comment would be very appreciated.
Hi,I am trying to create a development database server (make use of an old machine), with which to learn about sql 2005 and oracle etc. I'm using VS 2005 Beta 2 on my development/workstation machine.My workstation and the prospective server are connected via a router and can 'see' each other.I have installed win 2003 server on two seperate partitions (multiple boot) and installed sql server 2005 on one partition and will install oracle 10g on the other. (I understand these two databases can run on the same machine/OS, but I just wanted to keep things tidy and I won't be using them at the same time, so ...).My question is how do I/should I configure win 2003 server / sql server 2005 on my server machine, in order to be able to connect from my workstation via vs 2005 beta 2 ?Any suggestions or resources on configuration appreciated.
View 2 Replies View RelatedWe have implemented a very small reporting database which has a main table that started off small and has now grown to around half a million rows. Initially, there were no indexes on the table apart from a clustered index, but as the data has grown, performance has dropped and so we have added a number of indexes. This has resolved the performance issues.
Before creating the indexes SQL Server had auto created a number of statistic objects (_WA_Sys_000... etc). After creating the indexes, new statistic objects where created for the new indexes. In some cases, there are duplicate statistics (auto and index) for the same columns.Should I go through and drop the duplicate auto statistics? Will having duplicates cause issues at all?
I am running both SQL Server 2000 and SQL Server 2005.
Lets say I have a live database that is version 1 for an application. The database is copied onto a development machine to develop version 2 of the application. I want to be able to take a snapshot of the database and then get a program to write all the changes made after the snapshot into sql code. This is so I can run this sql code on the live database and transform version 1 to version 2.
Is there any program/tool that will allow me to do this?

At one of your client sides we have configured Always on with synchronous mode.Also we have schedule rebuild index and update statistics job which runs in night every alternate day. the issue is there are more then 100 sleeping queries which is blocking update statistics job.
I have to stop update statistics job manually once i come to office manually.
Once I have killed blocking sleeping query but then other sleeping query blocked it and so on.
I am really puzzled by an apparent difference between table index key column order and its statistics order. I was under understanding that index statistics mirror index definition. However, in my db 2470 index ordinal definitions match statistics definition but 66 do not. I also can reproduce such discrepancy in 2008 R2, 2012 and 2014.
As per definition,
stats_column_id
int
1-based ordinal within set of stats columns
This script duplicates this for me.
BEGIN TRAN
GO
use tempdb
GO
CREATE TABLE [dbo].[ItemProperties](
[itmID] [int] NOT NULL,
[cpID] [smallint] NOT NULL,
[ipuID] [tinyint] NOT NULL,
[Code] ....
The result I get is this:
object_id stats_name
stats_column_list
1525580473 PK_ItemProperties_itmID_ipuID_cpID itmID, cpID, ipuID,
and
object_id index_name
index_column_list
1525580473 PK_ItemProperties_itmID_ipuID_cpID itmID, ipuID, cpID,
Also a query I used to discover this in my db is:
WITH stat AS
(
SELECT
s.object_id
,s.name as stats_name
,(
SELECT
c.name + ', ' as [data()]
FROM sys.stats_columns as sc
[Code] .....
I have been asked to create a report for one of our clients. The report is pretty basic but I am concerned about the overheads with my planned approach.The report is at a table and field grain to include values for:
* Min column value
* Max column value
* Number of discrete values
* Number of populated values (not NULL)
My current plan is to have a cursor over a limited view of sys.tables and sys.columns that will run a dynamic SQL query to import the results into a table that I can then output.There must be a better way of doing this and I don't have access to any DQS services.
We are using SQL Server 2012 for both production and development server. Currently, i have plan to transfer the full backup of SQL server database to the development server and then restore it on the development server for testing purpose, so we don't want to disturb on the production.
I have successfully backup the database from the production server and transfer to the development server. however, i encounter some difficulties when trying to do restore. my question is:
1. do i need to firstly create an empty database on the development server and then restore it into this empty database? say i create database call "Test2", then i perform a restore into this database.
2. currently, there is already an existing database being restored previously in the development server and this database is actually the older version of the backup that being restored by the previous engineer. should i remove this database first and restore a new one or both of the database can coexist as long as we put different name for the database?
Production and development servers are on different domains and they do not trust each other. How do I import data from the table t1 from a database db1 in production and load it into table t1 inside database db1 in development?
View 3 Replies View RelatedHi all! I know I might sound stupid, but I have this problem. I have developed my database on my laptop which does not use Active directory. Lets say I access the database with: SPIDERMANDB1 on SQL server, where the name of my laptop is SPIDERMAN, and the database is DB1. Now, I create an SQL script from sql server and make the necessary changes, like changing the computer name to say, SUPERMAN where my deployment server's name is SUPERMAN. But when I run the SQL script on the SUPERMAN server, it gives me an error like: "User or role SUPERMANDB1 does not exist in this database". I have deployed databases in this way on servers without Acive directory, so I'm sure its not a mistake on my side. So how am I supposed to go around this active directory thingi! Please help me out! I'm counting on u guys!

If I rebuild some indexes that are above 30% of average fragmentation, should I after that update statistics?
Also, How can I see if I Need to update statistics^on the tables of my database?
Hi
Can we use BCP AND/OR BULK INSERT to do development server databse refresh from production server . I have to do this by following the rules below:
- no truncation of source table
- update of changed or new records only.
I know we can use replication, dts and other methods for this but I need information about this one.
Thanks

Hi Team,
We need to get the data from our third party CRM vendor. CRM vendor will provide us with .txt file on their folder each night and we need to get those data into our database. I know that SSIS should be able to do this for us. Is there any tutorial of how to do this job in SQL Server 2005? Thanks in advance.
Hi,
This requirement is for our development and test environment. We have a database server which we use for development hence many changes are done on the database objects on daily basis like tables def changes, view def changes, sp changes, new sp etc.
On the other hand our testing team connects to another database server where they perform testing hence any internal test release would need the changes like tables def changes, view def changes, sp changes, new sp etc.
Since testing team already have their test data set in the test environment hence they want to keep their data but new test release should only provide with datbase object changes. The difficult part is, we have over 500 tables and about 1000 views and somewhere about 400 stored procs, so its not possible to manually perform the above task.
I dont do database admin job hence clueless as what would be the best way to accomplish the above. Pl advice.
we are using sql server 2005 on both test and dev environemts.
cheers!

Hi all,
We have a website with a database connected to a SQL server. I need to copy that database without the data onto a CD so I can place the program on another server?
Any help would be greatly appreciated.

Thanks i advance!

How do i make a new database file and then copy all the tables and data out of an old SQL file into it? I just want to see if rebuilding the file helps with a corruption issue i have been having with the log file.
