This is certainly helpful. Thanks a lot 
Now, is there any way we can display additional information for "actually which columns the data is not matching" ?

Hi Vishal!
Take a look at my blog "Compare the content of two tables" at http://www.cubido.at/Blog/tabid/176/EntryID/77/Default.aspx. It describes how this can be done with a tool that comes with SQL Server 2005.

Rainer.

Hello, I am trying to develop a program that uses data from a DBMS. But the problem is that I don't know which one(DBMS) I should use. The program is going to handle a couple of tables with a few thousands of records each. I have in mind MS-ACCESS and MySql but recently I discovered FIREBIRD which is released under the GPL licence(completely free to distribute with my software or at least this is what I understood).I am new to theese matters so please I need your advise...

Have you considered SQL Express, it is also free to distribute and will more than be able to handle the workload you are describing. It also has a GUI admin console and fully integrates into all versions (even the free express ones) of Visual Studio. As far as Firebird, never used it so can't say.

For a few thousand rows and freely distributable you may want to consider the size of the extra files you are distrubuting and how easy it is to have your installation file connect everything up on installation.
* SQL Server 2005 Express Edidtion is quite bulky, so you may not want that.
* SQLITE might also be appropriate for you - It is public domain and I think there are only one to two DLLs that you need to add to you to your install.
What I'd do is draw up a matrix containing all the database products you are looking at across the top and all the features you are interested in down the side. For example:
DB -> SqlServer MySQL Firebird SQLITE
/Feature Express
Redist.. Y ? ? Y
Install
Size Large ? ? 1-2 DLLs

Hi, folks!
I hope I can explain this properly...
I have two tables. One is a list of people's first and last names and there is an Identity column to uniquely select the proper row.
The other table is a list of email forwards; in other words I want to keep track of how a particular email is passed about with the group. This table has a column that uniquely id's the message, a column for the id of the forwarder and a column for the id of the forwardee. The id's come from the usernames table. So far, so good.
<br />
TABLE [Employees] (<br />
[idnum] [int] IDENTITY (1, 1) NOT NULL ,<br />
[firstname] [varchar] (50) NOT NULL ,<br />
[lastname] [varchar] (50) NOT NULL ,<br />
)<br />
<br />
TABLE [tblDownLogForwards] (<br />
[idnum] [int] IDENTITY (1, 1) NOT NULL ,<br />
[TicketNumber] [int] NOT NULL ,<br />
[IdForwardFrom] [int] NOT NULL ,<br />
[IdForwardTo] [int] NOT NULL ,<br />
[ForwardDate] [datetime] NOT NULL <br />
)<br />
Now, I want to report these forwards, but of course I want to make it easy to interpret so instead of the id's I want to include the user's first and last names, something like this:
<br />
msgNum - ForwarderFirstName - ForwarderLastName - ForwardeeFirstName - ForwardeeLastName<br />
How do I specify an SQL statement to replace the user id's with their names? I thought the following might do the trick, but it only selects records having the same id as forwarder and forwardee:
<br />
select ticketnumber, forwarddate, Employees.lastname as FromLast, Employees.firstname as FromFirst, Employees.lastname as ToLast, Employees.firstname as ToFirst from tblDownlogforwards inner join Employees on Employees.idnum = tblDownlogforwards.IdForwardFrom and Employees.idnum = tblDownlogforwards.IdForwardTo<br />
If I elliminate the last equality, I get records where the ForwardTo columns have the same person's name, even when another id is present.
I'm very perplexed by this...
Thanks!

Eric,
Bingo! Thanks a bunch!
BTW, love your .sig. A guy I worked with many years ago once wore a tee-shirt which said on the back:
"I must hurry and catch up with the others, for I am their leader!" I never knew where it came from. Thanks!

I have one stored procedure, and it having UPDATE and INSERT statements, The INSERT / UPDATE queries are inside a Begin transaction, if the transaction fails then rollback the transaction otherwise commit it.
If the error occur rollback the transaction as well as i want to catch the exception and throwuh it to the user in the DA Class
I am calling the stored peocedure in the DA Class
please tell me any suggestions
Awaiting for reply
thanks

IF @@ERROR <> 0
ROLLBACK
RAISEERROR...
ELSE
COMMIT
|
|
|
|
|
Or don't have the transaction in teh sproc, but handle it through the DA class:
SqlTransaction tran = new SqlTransaction(conn);
try
{
... call sproc
tran.Commit();
}
catch (SqlException sqlEx)
{
tran.Rollback();
}
|

Be careful with this approach. Some Transactions may still get automatically rolled back, which will cause the rollback statement in the code to throw another exception.
Typically, SQL server rolls back transactions when a severe error or a connection loss occurs. This can be handled by issuing the rollback transaction in a nested try catch, and handling the error if the transaction was already rolled back.
We need to graduate from the ridiculous notion that greed is some kind of elixir for capitalism - it's the downfall of capitalism. Self-interest, maybe, but self-interest run amok does not serve anyone. The core value of conscious capitalism is enlightened self-interest.

how can i return 0 (false) for an error to insert data in SQL database. i am using ASP.Net (using vb.net) to call the stored procedure....
my procedure is...
CREATE PROCEDURE Insert_Book (
@arg_Title VARCHAR(255),
@arg_Price VARCHAR,
@arg_PublishDate DATETIME,
@arg_BookID INT OUT)
AS
DECLARE @rc Int
BEGIN
INSERT INTO
Book (
Title,
Price,
PublishDate )
VALUES (
@arg_Title,
@arg_Price,
@arg_PublishDate );
/*SELECT @arg_BookID = @@IDENTITY;*/
IF @@ERROR <> 0
BEGIN
/*SELECT @rc = 0*/
/*Print convert(Varchar,"An error occurred while adding the new Book information")*/
RETURN (99)
END
ELSE
BEGIN
/*SELECT @rc =99*/
/*PRINT Convert(Varchar,"The new author information has been loaded")*/
RETURN (0)
END
procedure call is...

How do I access Query Designer from Microsoft SQL Server Management Studio? I mean the equivalent in SQL Server Enterprise Manager of
Table -> Open Table -> Query
I just can't find the equivalent from the menus.
Also how to access DTS?
Probably all very obvious!
Thanks

Just open a table and then click on one of the toolbar buttons on the lower toolbar that appears. You have diagram, sql and criteria buttons.

I have this script here. But I need to redo it as a sub Query can someone help me?
SELECT
fp.flt_numb,
a.name as 'destination airport',
a.cty_iata_code,
b.name as 'possible landing airport'
FROM flight_profiles fp
JOIN airports a
ON a.iata_code = fp.to
JOIN airports b
ON a.cty_iata_code = b.cty_iata_code
ORDER BY fp.flt_numb;
|
|
|
|
|
|
I need to re-write this as a sub query:
Select
f.FLT_NUMB as 'Flight Number',
b.Name as 'Arrive Airpots',
a.Name as 'Airports'
from airports a
join flight_profiles f
join airports b
on a.cty_iata_code = f.to and b.iata_code = f.to
group by a.Name
order by f.flt_numb
|
|
|
|
|
I got re-wrote like this
select
d.flight_no,
d.destination,
a.Name as "Alternative Airort"
from airports a,
((SELECT b.FLIGHT_NUMBER FLIGHT_NO,
b.DESTINATION DESTINATION,
a1.cty_IATA_CODE AS CTY_CODE,
a1.name as airport_names
FROM AIRPORTS a1,
((SELECT FLT_NUMB FLIGhT_NUMBER,
F.TO DESTINATION FROM FLIGHT_PROFILES F) AS b)
WHERE b.DESTINATION=a1.IATA_CODE)as D)
where a.cty_iata_code=d.cty_code
order by d.flight_no
and its work fine.

Hi,
well i think i'm so stupide to ask that but i really tried ma besqt with it & it doesn't work
i created a stored procedure in this procedure i have 1 parameter type datetime
& i want to select * from a table where day(this table.dat_start)/month(dat_start)/year(the parameter) = the parameter
i will make it more clear
supposing parameter is '02/05/2006'
(select * from season where day(dat_start)/month(dat_start)/year('02/05/2006') = '02/05/2006')
it dosen't want to of course because the two types are defferent but i did a convert & it dosen't ant too
(select * from season where convert(datetime,day(dat_start)/month(dat_start)/year('02/05/2006')) = '02/05/2006')
& i did a cast & no result
(select * from season where cast(day(dat_start)/month(dat_start)/year('02/05/2006')as datetime) = '02/05/2006')
