I have one sql server 2005 database and its size is 16 GB , i rebuild indexes on a table which is having size almost 12 GB (item Master)
* i know its not normalized but i get the db in this condition
dbcc dbreindex (item_master,'',80) and now size becomes 26 GB should i shrink database or physical files showing 50 % free space available.
what else can i do to increase the db speed , already check ,Disk I/O , Memory , temp DB , network Packet size.
Planning to do
UPDATE STATISTICS item_master
dbcc updateusage ('DB')
DBCC INDEXDEFRAG (DB,'item_master')
DBCC dropcleanbuffers
dbcc freesystemcache ('all')
dbcc cleantable (DB,'item_master') --
Anything else which can speed up the things from database point of view

How many rows are in the table? How many fields? What kind of data is it? Are your indices appropriate for the way you are wanting to extract the data? Can you update the structure to improve the performance or are you stuck with it?

Hi,
I have a database on webserver, when some one gives any order from website then data comes into this database. Now i'm fetching these data from websercer to our local machin's dataabse. for this purpose i'm using en exe which contains stored procedure for fetching the data.
These stored procedures takes 5-7 min to fetch the data from webserver. Now the problem is that at the time of execution of stored procedure no one can give the online order because of database busy.
My question is that how i can improve the system so that one can give online order at the time of execution of stored procedure.
Thank you..

can you tell which Database Server are you using and do you have any maintenance plans scheduled.

Not without knowing a lot more about your system - table sizes, indices, configuration, usage, etc etc. One thing you could try, in your stored proc use (nolock) on your reads, this may help

No any complex thing is their in my system. only i'm selecting data from web sqlserver table and inserting it in to local sql server tables.

yes, but I bet there is a where clause, so are those columns indexed? Its far too complex to do in a fotrum without any table defs, index defs, usage stats etc etc. Run your query through query analyser and look at the execution plan, that should at least give you some clues.

In SP there is nothing but only select and insert statements, i mean i'm selecting new data from web sql server and inserting it into our local sqlserver.

I always assumed that accessing the same Access database by multiple users somehow just works, i.e. many users can read and write to an Access database in a shared folder on the network.
I assumed the same functionality with SQLce.
However, I've never been able to test it.
Does it work as I assumed ?

Happens way too often and although Access provides locking-mechanisms and the likes, you'll find that it fails to perform adequately.
SQL Express is also available free, and you can easily upsize your Access-database to SQL Express.

Yes, it works as you assumed... However, in both cases, each user needs to have their own front end installed (whether that's an Access DB, VB, whatever) You don't want a bunch of users opening the same file at the same time (ie: a single access database containing both tables as well as queries, forms and reports....)
|

the Access DB is used to only store data and it will be located in some shared folder on the network.
There's about 10 client apps (which is probably what you meant by "front end") that will, at any point of time, read data from the database and also write data to the database.
Forms will not be implemented in the database directly.

|

Access and SQL Server will both be fine as a back end then...
|
|
|
|
|
let us take the server is down and all the data are corrupted. other than backup,replication, log shipping what can we do to get back the data or make the customer to proceed with the work ?

Ah, but this time some of it is bold and underlined (I guess for those of use that were too dim to understand the first time).

I'm waiting for a reply, but I don't have a backup, and my response will be then you don't have a client!

Hi Thanks For your reply ,
The thing is that i have one table in which date is stored in column(datataype nvarchar)
There are more than lacs of records in this table.
so i want to convert this field into following format
ORIGINAL FORMAT OF FIELD IN TABLE (DATATYPE:-NVARCHAR) => 30/11/2009
I WANT INTO FORMAT : 30112009
AND ANOTHE FORMAT : 30/11/2009(SMALL DATETIME)
Please help me out.
I tried the solution which you gave but its giving following error
"Msg 8115, Level 16, State 2, Line 1
Arithmetic overflow error converting expression to data type smalldatetime.
"
Please help me out
|

Not sure why you get this error.
declare @a nvarchar(20)
select @a = '30/11/2009'
select convert(smalldatetime,@a)
gives me 2009-11-30 00:00:00, which is correct. How it is displayed (i.e. 30/11/2009 or 30112009) is down to your format mask, SQL Server simply stores the datetime value as a number.
Please, before posting any more questions around this, use the F1 key and read up on date time data types.

What you said is very correct , i am not denying it. The thing is that i am inserting into destination column(smalldatetime) from source column(nvarchar) and the number of records are around 4lac.
I am inserting through sql script in query analyser. After insrting some 20k records it generates that "Arithmetic overflow error".
This was task given to me. thats why otherwise i could change my destination column to datetime. Its working.
But I am forcebly want it to smalldatetime as this was task for me.

Have you done any data analysis to make sure that all the values you are trying to convert fall into the acceptable range for smalldatetime values?
Perhaps you have a record (around the 20K mark) that has a typo in the date, and instead of 30/11/2009 it's 31/11/2009 (which isn't valid) or 30/11/9999...
