I have not seen this attempted for many years, not since there were hackers and viruses. If somone gets hold of your connection string they have access to your database. If you are not managing your security VERY tightly you have a serious problem.
They invented web services to address this problem (among others) your client should not connect to the database directly.

Thanks Holmes,
Can you sugest me the other helpfull ways to accomplish this.
Also i don've idea about using webservice for data access.
Can you help me in any ways.

You could try the following:
Data Source=[server name or IP];Initial Catalog=[database name];Persist Security Info=True;User ID=[User];Password=[@@#$%@#@#@*****]

Can anyone tell me where the default value for the logfile path is stored? I presume it is in one of the system tables somewhere...
The problem is that at the moment, using the "Create New Database" option generates a path of:
...C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\YourDBname for the DB and
...C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DAT\YourDBname for the logfiles
Obviously I can change this at creation time, but I'd rather that my colleagues and I don't have to do this every time (sigh).
Google (so far) has not been my friend.

I have never tried this myself, but what happens if you change it for the "model" database?
|
|
|
|
|
I see where you are coming from - but model database files location are both correct (i.e. both \DATA)
Thanks for your attention.

In Management Studio, right-click the server in the Object Explorer tree, select Properties, go to Database Settings, and change the paths under Database Default Locations.
IIRC, you need to restart the SQL Server service before the change takes effect.

Woohoo! Yup - the default locations were blank (dunno where it was getting them from before  )
Changed and successful - did not even have to restart SQL server agent or anything.

Hello!
My hosting company gave me a backup of my online DB (a BAK file), which I've attached to my local SQL Server, in order to perform the tuning locally at first, and then on the online DB.
I use a trace file, which was created by the Profiler, that ran on the online DB.
I get no suggestions at all, but errors. The most frequent errors are:
1. Event does not reference any tables
2. [Microsoft][SQL Native Client][SQL Server]Could not find stored procedure '(some stored procedure name)'.
Thanks in advance!

Hello everyone ,
I am trying to back up a database using VB.net . Is there any coding for that ? I need to backup a database connected to !!! Not a database that is not connected to !! Because when I open my program it will automatically connect to the database .

An Access Database is just a file... you could do a file copy to a backup location. I'm not sure that the mdb file being opened will affect this process. If it does, you could always temporarily close the connection and restore?
|
|
|
|
|
Hy ,
Thx for ur answer . But whats the code like ? Check if the file exist and the copy it to another directory on a button click ? How the code look like ?!
Thx again.
J ,

You could do something like that... that would be the easiest. Only thing is, you will need to make sure that the backup copy works. So restore the database back to original location and check that it actually has been copied over correctly.

Can any one tell me if it is possible to get the page total in the body section of a report....not the footer...thanks in advance
|
|
|
|
|
I think you'll find that the page total is only produced AFTER the page is rendered therefore it is not available inside the actual page. Having said that I beleive you can assign it a variable and access the var from withing the page, this will reflect the current page - 1. Kludge but we have used it.

The problem for me is not calculating the pg total. The main problem is that if the table is spanning multiple pages then how do i get a report item to appear on each page below the table so that i can display the total without using the page footer. i cant use the table footer and cause it to repeat on every page because the table footer is processed only once at the end of the table

This is the common problem when you have installed the sql server express edition.
First you have to make sure that your Connection String is Correct.
most likely this problem is caused because in default condition sql server express edition cannot allow remote connection.
so please do following
Open "SQL Server Management Studio Express"
Connect to your Database
Right Click on the Database in Object Explorer
go to Properties
select "Security"
Now in Server Authentication Mode
select "SQL Server And Windows Authentication Mode"
Restart the SQL Server Service (if you dont know how then restart the computer )
if still have the problem then
go to
Start ->
SQL Server 2005 ->
Configuration Tools ->
SQL Server Surface Area Configuration
Then select "SQL Server Surface Area Configuration for Service & Connection"
now select "Remote Connection" ->
tick on "Remote and Local Connection" ->
again tick on "Use Both TCP/IP and Named Pipe"
Now go to Service "Stop" it and then "Start" it.
if you still have the problem then double check your connection string

Hey guys, I have got two tables, in PurchaseT I store the data for a purchase (Amount and PurchaseCode), in PurchaseCodeT I store the names for each code, (1 = Grocery, 2 = restaurant and ...) now I have a select command which get some records from PurchaseT, but instead of the codes I want to have the name for each code ... how can I pull that off !!
Thanx heaps !
Mr.K

SELECT P.Amount, P.PurchaseCode, C.Name AS PurchaseCodeName
FROM Purchase P
INNER JOIN PurchaseCode C ON C.PurchaseCode = P.PurchaseCode

For MS SQL Server 2000...
Sometimes I want to define and use variables within a View, but it appears that is not possible.
That includes using table variables in Views. I'm new to SQL. Is there a way to do this? If not can someone explain the reason for it being not allowed? Google hasn't been much help on this one. Thanks
|

Variables are procedureal constructs. A view is for creating alternative views of your data only. Not sure what it is you want to do, but once your view is defined to you can "pass a variable" to it from your stored procedure or batch statement like this:
SELECT col1 + @myVariable AS Col1Alias
FROM myView
WHERE col2 = @myVariable2
Just think of a view as a derived table instead of a script or code file and that should help. The kind of stuff you're describing can be done w/in a stored procedure, that's what you want to use in most cases.

Views just execute select statements, and act very similarly to tables, you can do formatting and things in a view, and limit the columsn in one or more tables that someone has access to. that and formatting and long complicated joins are their main purpose i believe, its a lot better to put a long complex query in a view and have a simple select in your code, if you're using it in an application, makes it easier to change if something is wrong or table layouts change. If you want to declare varibles or run other queries, you can use a stored procedure. you can run cursors, use varibles, even run other stored procedures in them, pretty much anything youcan do in query analyzer. in sql 2000 if you need a result set back just select it back..select <whateveryouwant> in teh sp...be careful tho because you can do multiple selects like that in one stored procedure, and when it executes it will return multiple result sets, which can cause problems if you're using an app (win forms or web) to read the data.
