Hi all. A few days ago i installed mcafee total protection 2007 and that disabled my internet connection totally!! I couldn't fix it so i had to uninstall it. After uninstalling mcafee total protection 2007 still i couldn't join Internet!!
So i got mad and went and made repair installation of windows xp pro. After repair installation i couldn't activate it since Internet connection was still not working!! So i went and installed another copy of xp pro on different folder and named it WINDOWS (old one was WINDOWS2).Thanks god now i could join Internet but all my shortcuts and menu items are not visible.
Unfortunately I can't even start sql server 2000 either!! could any one tell me what should i do in order to get access to all database tables and data that i had in sql server and make a back up. I didn't install any new sql server yet. I be happy if an expert tell me what should i do. The installation folder of old windows(WINDOWS2) is still available along with sql server installation folder.Thank and looking forward for reply.

Somewhere in the Sql Server folders (normally under Program Files on your root drive unless you installed it somewhere else) there should be some files YourDatabaseName.MDF and YourDatabaseName.LDF.
You can take these files and from the enterprise manager 'Attach' them.
EDIT: Oh and if you hadn't guessed, stay away from mcafee products :P

Thanks for your reply. could you tell me the steps to attach them to new installation? I hate mcafee it created too many problems for me!!

Hi, im using application settings in a class library which implements a data tier. I then have a main application which references this class library. This is more of a query than a big problem, its just that when i access the settings via the ConfigurationManager in the data tier class i have to use the fully qualified class name:
i.e. it only works by typing the following:
ConfigurationManager.ConnectionStrings["AppDatabase.Properties.Settings.dbConnectionString"].ConnectionString;
why can i not just use:
ConfigurationManager.ConnectionStrings["dbConnectionString"].ConnectionString;
even though dbConnectionString exists in the settings file, it only works when it is fully qualified. I have seen many example using only dbConnectionString. Is it because i have multiple references to other class libaries in my main application?
Thanks,
Chris

I am very new to sql and databases.....
I am currently using Access and I have a database with about 1000 rows. I am trying to select 50 RANDOM rows at a time, how do you write an access sql statement for that? So far I have this....
SELECT*
FROM Computer
ORDER BY RND();
It returns all the results, but I just want to set it up so I can have it return as many as I want.
Please Help!

In sql you may try this:
select top 50 * from computer Order By NewId()

Thanks for the quick response, It is still giving me the whole list it isn't cutting it down to 50.

Hi,
I have the following query. my message field is of datatype text. But I want to grag just first 50 characters + ...
from that "message" field. How can I do that.
The following is my sql statement
select tck.ticketid,tckmsg.message
from tbtickets tck inner join tbticketsmessages tckmsg
on tck.ticketid = tckmsg.ticketid and tcktstatusId = 1
seema

Seema,
You can use the 'substring' function in sqlserver 2000.
select substring(column_name, start_position, length)
so your query might be:
select tck.ticketid,substring(tckmsg.message, 0, 50)
from tbtickets tck inner join tbticketsmessages tckmsg
on tck.ticketid = tckmsg.ticketid and tcktstatusId = 1

you can use following :
-----------------------
CAST (tckmsg.message AS VARCHAR(50))
your query should be the following
select tck.ticketid,CAST (tckmsg.message AS VARCHAR(50))
from tbtickets tck inner join tbticketsmessages tckmsg
on tck.ticketid = tckmsg.ticketid and tcktstatusId = 1

Hi, i have a class library which implements a data access tier. As i used the automated designer for the dataset it automatically added an app.config in the class library with the string to the database:
<connectionstrings>
<add name="AppDatabase.Properties.Settings.dbConnectionString"
="" connectionstring="Data Source ="D:\Chris\db.sdf"" providername="Microsoft.SqlServerCe.Client">
I then use this data access class library in my main application, however how can i change and update this connection string and point it to a different file at runtime? I would like to be able to select a different database but it seems (from breakpoints in the generated table adapter code - InitConnection()) the default values are being called (in this case from the xml app config above).
How can i get, or indeed override the connection string setting for the database, whilst at the same maintain all the other settings which are in place for the main app (ie user preferences, persistent settings etc)? I tried creating a setting in the main default application of dbConnectionString, but it always picks up the one from the AppDatabase class library namespace.
Thanks in advance,
Chris

Move the settings from the app.cofig in your data access library to the app.config in the main applicaiton. .NET Framework will search first for a configuration file as the same name as the assembly, if not found it will use the app.config, then machine.config

do you mean physically open the config files? i copied:
<connectionStrings>
<add name="AppDatabase.Properties.Settings.dbConnectionString"
connectionString="Data Source =D:\Chris\Debug\db.sdf"
providerName="Microsoft.SqlServerCe.Client" />
</connectionStrings>
into the app.config of the main app and all seems to be good. I guess when accessing the properties and settings through the property manager i will have to use the full namespace reference 'AppDatabase.Properties.Settings.dbConnectionString' rather than just dbConnectionString?
How come microsoft does not have an automated way to copy all the class library settings into one composite settings file when the class libaries are referenced from the main application?
Thanks so much for the help

Yes will need to use 'AppDatabase.Properties.Settings.dbConnectionString' because that is the name, not 'dbConnectionString'
<connectionStrings>
<add name="AppDatabase.Properties.Settings.dbConnectionString"
connectionString="Data Source =D:\Chris\Debug\db.sdf"
providerName="Microsoft.SqlServerCe.Client" />
</connectionStrings>
ConfigurationManager.ConnectionString["dbConnectionString"] will search the configuration file of the same name as the assembly if it exists, then the one in the next folder, if any, then web.config, etc.
So if the above entry was in myassembly.dll.config and this one was in app.config (or web.cofig)
<connectionStrings>
<add name="dbConnectionString"
connectionString="Data Source =D:\Chris\Debug\db.sdf"
providerName="Microsoft.SqlServerCe.Client" />
</connectionStrings>
Then ConfigurationManager.ConnectionString["dbConnectionString"] would use the app.cofing entry not the one in myassembly.dll.config.

Mark,
you are most informative thank you. I have one final question, when i edit the projects settings in visual studio, it automatically adds the fully qualified namespace for the setting, is this default behaviour? Not that this is a problem it just means i have to fully reference the entire setting name, or i can edit the setting name and remove the AppDatabase.Properties.Settings to leave just dbConnectionString which indeed works just fine as you say.
Many thanks for your time you have saved me a big headache!
Chris

I couldn't find a menu item on Enterprise Manager for viewing database logs.
I meant the .ldb file [ correction: should be .ldf file ]. I would try using notepad except the file is over 700 mb.
Thanks.

The Jet database engine uses .ldb file information to prevent users from writing data to pages that other users have locked and to determine who has other pages locked. If the Jet database engine detects a lock conflict with another user, it reads the .ldb file to get the computer and security name of the user who has the file or record locked.
In most lock conflict situations, you receive a generic "Write conflict" error message that allows you to save the record, copy it to the Clipboard, or drop the changes you made. In some circumstances, however, you receive the following error message:
Couldn't lock table ; currently in use by user <security name=""> on computer <computer name="">. .

Sorry, I meant ldf file, not ldb file. I was referring to SQL Server database.

You don't.
The log contains all the information required to roll forward or back to a point in time. If you want to see what the state of the database was at a particular point in time, back up the transaction log (WITH NO_TRUNCATE to keep the current log data, so you don't affect your regular backup sequence), then restore the last full backup under a different name WITH NORECOVERY, and restore the log backup WITH RECOVERY, STOPAT and the time you want to recover up to.
The log contains binary log records indicating the operations that were performed, plus the data of any rows deleted, the new data for any rows added, and both the before and after versions of rows updated. For information on the log format used by SQL Server 2000, see the book "Inside SQL Server 2000". There's an updated set of books for SQL Server 2005 - presumably you want the Storage Engine one.

A trigger was mysteriously added to one of our tables. What I would like to find out is who did it (nobody is admitting it). Looks like there is no easy way to find that out?

Hi,

myCommand.CommandText = @"BACKUP DATABASE DataBase1 TO DISK = 'C:\MyFiles\DB_BAckup.bak'";
myCommand.ExecuteNonQuery();
But It doesn't work, I get an exception "Could not locate entry...."
What does it mean?
Thanks in advance.
