This is where DBAs earn their living, I suggest you either start reading a number of articles on database specific sites (sqlservercentral is one) or hire a DBA consultant to design a maintenance regime for you.

I agree with Mycroft (second time today) this is more of an art than a "do it this way" type thing. There are so many variables that there is no easy answer.
Some things to look into (learn about) would be Data Base Tuning Advisor and audit trace for a start. These may or may not help.
There are also several third party programs that might help, again Google may help. You might look at Idera as one provider.

Hi,
I just want to understand CAL licenses of microsoft sql server!
If I implement Service Oriented Architecture then also I need to buy CALs for all my clients?
And is it different from SQLEXPRESS to SQL SERVER?
Thanks,
Divyesh

It is best to go to Microsoft's books on line to get their take on CAL's
There are two types of licensing server and client side. It depends mainly on how many users as to which what to go.
Good luck

If u know or can provide the link which mention the service oriented architecture with sql server CALs?
Thanks,

Had to Google SOA as I have always been in small shops. You might look into the 'per CPU' license.

Best to go to a bloody magician, you certainly can't rely on a forum post to clarify this subject. MS licencing is one of the most arcane subject in the software industry. Good luck.

One more thing is there, if a public hosted web site is there. It has one web service which populate data from sql server.
Now you never know how many connection will be there for that web site, in that case how to buy CALs?
Same thing apply in my case!
Even though I dont have public server. It will be a static ip server in organization's intranet! There will be one .net application which has hosted one .net remote object and my client communicate with that .net remoting object and fetch the data!!!
Thanks,
Divyesh

Mycroft brings up a good point, MS licensing is a nightmare. Thus if you go to the MS SQL Server site they have several pages of information.
As to a general license that would be per CPU.

Partitioning a table is NOT what you want to do, that is dealing with VERY large tables and requires DBA skills.
You are after a data structure.
You have 3 tables crammed into 1.
Employee
EmployeeID
EmployeeName
StateID
Country
CountryID
CountryName
State
StateID
CountryID
StateName
Employee View
Select *
From Employee E
Inner Join State S on S.StateID = E.StateID
Inner Join Country C on C.CountryID = S.CountryID

How to keep one more backup copy of current database.. where i am using only single database to keep my 10000 record of info. if something goes wrong what to do...So i want to keep one more copy of that keeps continues changes info of main database..

No don't keep a copy of the database keep a BACKUP of the database. If you are using 2008 you can get compression with the backup and keep multiple versions. A typical backup regime is something like
backup every night mon-fri
keep the last 5 fri backups
backup end of month regardless of the DOW and keep for 12 months
keep the EOQtr indefinately

Look into replication (publication) or log shipping. Depending on your usage and resources the type you use may very.
You can replicate to the same SQL server.

Hello,
I need to write a stored procedure in MySQL that loops through all rows in a table (the column types are TEXT and VARCHAR) and replaces certain characters in the column values with another character. For example, a certain column contains the text "ababa" and I want to change it to "acaca".
I can't quite figure out the part about replacing a character in a string with another and could use some help with this!
Thank you!

There's a Replace[^]-function in MySQL. You'd have to test if it also works for the TEXT-type field though

The engine should do that; you shouldn't.

Hello friends,
I restored My database in SQL 2005 of size more than 4 GB but it creates problem when i save picture (image data) in database.i.e i can't save it.So i searched for that problem and came to know that SQL Express 2005 has database size limit of 4 GB.
i upgraded it to SQL EXPRESS 2008 and restored it to there.Still it has the same prblem means i can't able to save data..
So what may be the problem.
Thanks in advance.

AFAIK SQL Server Express 2008 and 2005 have the same set of limitations, one of them being file size is 4GB maximum.
There are a couple of solutions:
- split your database over two or more files;
- don't store big objects (images) inside the database (keep them as individual files, just store the path in the DB);
- switch to a full-blown DB (SQL Server, non-Express).

Use Sql Express 2008 R2. That has a size limit of 10GB
"An eye for an eye only ends up making the whole world blind"
|
|
|
|
|
I learn something new each day. 10GB is confirmed here[^].

Thanks for your reply.
i upgraded sql 2005 express to sql 2008 EXPRESS WITH TOOLS that is
R2 version of SQL EXPRESS.
But still the same problem there....
