It won't get fragmented indeed, since you

Hope this helps

you expect a read-only file-system to get fragmented over time?

WHEN I RAN INDEXDEFFRAG..
THEN WHAT THIS RESULT MEANS???
PAGE SCANNED PAGE MOVED
245 0

You were right
"DBCC INDEXDEFRAG defragments the leaf level of an index so that the physical order of the pages matches the left-to-right logical order of the leaf nodes, thus improving index-scanning performance."

i have a database with a large log file database and i don't know how to do to make it smaller,,,
the file have a large area space what can i do???

You are not telling us what type of DB you are using. Beware of erasing log files or minimizing log levels since mistakes do happen and when they do, these files are life savers especially in production.

Do you know what recovery model you are using (simple vs full)? Are you backing up the database? What version of SQL Server is it?

but for this u need to make your database offline first and then run this code.

How should i check the positive value in sql server 2005 except the following?
declare @f varchar(2000)
set @f = '788'
print charindex( '-' , @f )
|
|
|
|
|
It would be nice if we could actually understand what you are trying to accomplish.
|
|
|
|
|
Check if it's larger than 0
DECLARE @f INT
SET @f = 788
IF @f > 0
BEGIN
PRINT 'It is positively positive!'
END
ELSE
BEGIN
PRINT 'That''s A negative there, Toto'
END

I had a project in MS access 2003 now I converted that to SQL server where there is some fields
in each table which has the hyperlink link to a scanned pdf file. while converting the files
the database is running very well but I can not get to my scanned files and the hyperlink is not coming in SQL server to click to get to the specified scanned files.just the path is coming in text format only
could you anyone help me.

Because that is what is stored. You cannot (as far as I know) store a hyperlink in sql, just text so you need to build the hyperlink when you retrieve the data.

If you are still using the Access front-end, just pass the text as a parameter to the VBA FollowHyperlink function and it will open.

Hi everybody
Actually i created a table in sql+, and inserting data using sql+ itself.But after i log out off the screen and log in again i see the data gone. How can i prevent the data from getting vanished without writing commit or set autocommit commands on everytime.

During interactive usage with sqlplus, Oracle also supports an AUTOCOMMIT option. With this option set to ON each individual SQL statement is treated as a transaction an will be automatically commited right after it is executed. A user can change the AUTOCOMMIT option by typing
SET AUTOCOMMIT ON or
SET AUTOCOMMIT OFF
whereas by typing
SHOW ALL
a user can see the current setting for the option (including other ones).
