There was a plus on that line too, but if you double click the error, which of those lines is highlighted?

It goes to this line
FROM DISK = @path + @filename
Thanks

What happens if you first modify the variable and then use only it in the restore, like:
...
SET @filename = 'C:\DATABASES\'+ @filename
-- Restore the database
RESTORE DATABASE @dbname
FROM DISK = @filename
...
|
|
|
|
|
Now it moved and Targeted the Following lines
WITH MOVE 'TNGoedit_Data' TO @path + @dbname + '.mdf' ,
MOVE 'TNGoedit_Log' TO @path + @dbname + '_log.ldf',
Thanks

Seems that the problem was found so try to do the same for all variables, like:
...
SET @movetarget1 = @path + @dbname + '.mdf'
...
WITH MOVE 'TNGoedit_Data' TO @movetarget1...
|
|
|
|

Create PROCEDURE [dbo].[sp_RestoreDatabase] <br />
<br />
@dbname char(32), -- the database name to restore as<br />
@filename char(32),<br />
@Results int OUTPUT<br />
<br />
AS<br />
<br />
set nocount on<br />
<br />
declare @path char(64)<br />
declare @dbmdf char(64)<br />
declare @dbldf char(64)<br />
set @path = 'C:\DATABASES\' -- the location of the backuped up database file (on the SQL Server)<br />
<br />
execute('sp_ClearDatabaseConnections ' + @dbname) --kill the existing connections to the current Database<br />
<br />
SET @filename = 'C:\DATABASES\'+ @filename<br />
set @dbmdf = 'C:\DATABASES\' + @dbname + '.mdf'<br />
set @dbldf = 'C:\DATABASES\' + @dbname +'_log.ldf'<br />
-- Restore the database<br />
RESTORE DATABASE @dbname <br />
FROM DISK = @filename<br />
WITH MOVE 'TNGoedit_Data' TO @dbmdf ,<br />
MOVE 'TNGoedit_Log' TO @dbldf,<br />
REPLACE,RECOVERY;<br />
-- Was the command successful or was there a problem<br />
if ( (select @@Error) = 0 ) begin<br />
SET @Results = 1<br />
end<br />
else begin<br />
SET @Results = 0<br />
end
and i tested it like this
DECLARE @Results INT
EXEC [dbo].[sp_RestoreDatabase] 'oBookingUFS','oBookingUFS',@Results out
and i got the Following Error
<br />
Msg 3234, Level 16, State 2, Procedure sp_RestoreDatabase, Line 27<br />
Logical file 'TNGoedit_Data' is not part of database 'oBookingUFS '. Use RESTORE FILELISTONLY to list the logical file names.<br />
Msg 3013, Level 16, State 1, Procedure sp_RestoreDatabase, Line 27<br />

Are you sure that this is the logical file name 'TNGoedit_Data' or should it be for example 'TNGoedit'
You can verify the logical names using RESTORE FILELISTONLY[^]:
RESTORE FILELISTONLY
FROM DISK = 'C:\DATABASES\oBookingUFS';

Hello everyone,
Two basic questions about transactions,
1. For single SQL insert/update/delete statement, are there any needs or benefits to wrap into a transaction?
2. I wrote T-SQL like this,
BEGIN TRY
Begin Transaction
...
commit
END TRY
BEGIN CATCH
rollback
...
END CATCH
my question is, is it a must to call commit explicitly just before end try statement? Any means to commit transaction automatically after end try statement?
regards,
George

It's always inside a transaction. Either implicit or explicit. If you don't want to be able to rollback the operation then it wouldn't matter, if you have logical error handling etc, then explicit transaction would be needed.
George_George wrote: is it a must to call commit explicitly just before end try statement? Any means to commit transaction automatically after end try statement
Basically commit point canbe anywhere, even at client side. However if you explicitely start a transaction, you have to explicitely end it. If you don't execute commit, database will roll back the transaction at the end of the session (unless other transaction handling is occurring after this transaction).

Thanks Mika,
1.
"If you don't want to be able to rollback the operation then it wouldn't matter, if you have logical error handling etc, then explicit transaction would be needed." -- I am confused. Could you show me a sample about the benefit please? My detailed confusion is even if I do not start transaction explicitly, I could still catch the error and handles it. 
2.
"Basically commit point canbe anywhere, even at client side." -- what do you mean client? No matther what kinds of API you are using or even using Management Studio directly, I think we are all "client" of database engine.

George

Yes you can if the error is 'technical' and SQL Server sees it as an error. But what happens if the error is logical. Consider following imaginary scenario.
- insert into a table
- check that some business rule apply
- if business rule is violated, undo the insert
The previous is very simple and it wouldn't be a problem to just change the order of the operations. However, this is not always the case.
Since there's typically no harm in using explicit transactions, personally I've decided to use them always.

I meant a scenario where your try catch is inside a stored procedure and a client application (whatever it is) calls the procedure. Ending point can be at the calling side so the procedure is actually just a part of a bigger transaction scope.

Thanks Mika!
"I meant a scenario where your try catch is inside a stored procedure and a client application (whatever it is) calls the procedure. Ending point can be at the calling side so the procedure is actually just a part of a bigger transaction scope." -- so in this scenario, client code (e.g. ADO.Net) starts the transaction, but what is the practice of writing store procedure code in this way? Do we also need try-catch and begin transaction/rollback/commit code in store procedure?
BTW: I have this confusion because I as a store procedure developer -- not sure whther client will start another transaction or not. So, how could I write code in store procedure which could handle both client starts transaction or store procedure self-start transaction?
regards,
George

How the transaction scope is defined is a matter of opinion. I think most people use the logic that stored procedure starts and ends the transaction. However, there are downsides especially if rollback is executed because in that case the whole transaction is rolled back, even if it's started outside the stored procedure.
So this means that you actually cannot decide alone what transaction scope will be used. The application may be affected by your decisions. You could use @@TRANCOUNT to investigate if transaction is started outside the procedure and in the logic of your stored procedure you would execute rollback based on the initial transaction count.
There's a very good article you should read: http://www.codeproject.com/KB/database/sqlservertransactions.aspx[^]

No, there are no benefits in this case.

Thanks Ashfield!
Two more comments/questions after learning,
1.
I want to confirm with you that if we call begin transaction, do you mean the only way to commit transaction is to explicit call commit?
2.
If I do not use begin transaction explicitly using begin transaction statement (the default behavior is to auto-commit for each successful statement), no other configurations to disable auto-commit for successful each statement -- means we could have chance to commit later in a batch manually explicitly?
regards,
George

Correct

No - the default autocommit will have happened

Thanks Bob,
Sorry one more question, there are 3 modes, autocommit, explicit and implicit. How to disable/enable implicit mode? 
regards,
George

I am using the following code to Add up the difference of two time fields but It's not showing the correct record when the hours part increases above 24 means It shows the correct addition only if It's between 24 hours. For example
WaitingTimeTotal (hh:mm:ss)
----------------
03:18:46
03:25:06
________
06:43:52 which is correct but
WaitingTimeTotal (hh:mm:ss)
----------------
03:18:46
03:25:06
16:23:46
07:24:20
________
wrong answer!!!
The code i am using is
convert(varchar,convert(DateTime, SUM(convert(real, ConfTime - EnterTime))),108)WaitingTimeTotal
Can you please guide me. Thanks in advance !

If you want to have total hour amount, this could be one way.
I used inline views to both generate a test data (inner one) and to ease the summary (the outer one).
select convert(varchar(50), datepart(hour, datesum) + (datepart(day, datesum) - 1) * 24)
+ ':' + convert(varchar(50), datepart(minute, datesum))
+ ':' + convert(varchar(50), datepart(second, datesum))
from (select SUM(convert(real, datecolumn)) as datesum
from (select CONVERT(datetime, '03:18:46') as datecolumn
union
select CONVERT(datetime, '03:25:06') as datecolumn
union
select CONVERT(datetime, '16:23:46') as datecolumn
union
select CONVERT(datetime, '07:24:20') as datecolumn) alias1
) alias2
Now the result is 30:31:57. Was this what you were after?

Well, if you have to ask this then you obviously have not grasped one of the important concepts of being a developer - DO YOUR OWN RESEARCH! Google gave about 1.5 million hits for "compare oracle sql server"

Comparing two different products this way is IMO impossible. Instead of comparing blindly features or capabilites or products in the overall product suites, you should concentrate on the requirements. If you can define what you or the customer needs, then there would be a starting point to conversation considering if one product can fulfill a requirement better than another.
