I am working on Windows mobile platform using C#. I am using Merge Replication to do synchronization between SQL Server2000 and SQL Server 2005 Mobile edition and t is working fine.
The Server Tables are copied in the Client DB. It works fine with one way, i.e., server pushing data to Client Database (in PDA), but when i tried to update from PDA database, server keeps over writting PDA databse.
The requirement is that before adding our PDA database as subscriber,there are some tables with same name and structure as in Server with some records. After that i added it as subscriber and sycnchronized.The tables in the server are going to overrite the records in PDA.My requirement is to not overrite the records and it should update the existing table.Is it possible....Can Any one Help meeeeeeeeeeeee plzzzzzzzzzz.

But i am getting value as 1 hour 10 minute like...,
But actual output is 10 minute only...,

take the difference in minutes only and then convert the minutes into hours & minutes
SELECT '2007-03-14 12:50:55.070' as login,'2007-03-14 13:00:55.070' as logout,
cast(DATEDIFF(minute, '2007-03-14 12:50:55.070', '2007-03-14 14:00:55.070') / 60 as int) AS h,
DATEDIFF(minute, '2007-03-14 12:50:55.070', '2007-03-14 14:00:55.070') -
cast((DATEDIFF(minute, '2007-03-14 12:50:55.070', '2007-03-14 14:00:55.070') / 60) as int) * 60 AS m

How can I update columns of three tables in on sql statement
|
|
|
|
|
Wrap it in a transaction - That way either all updates work, or if one fails then they all fail. From the point of view of any other process querying the database it will only see the complete set of changes, or no change at all.
|
|
|
|
|
Specify which table you want to update by using a JOIN. Here is an example of 4 tables, and an UPDATE to three of them.
CREATE TABLE people
( personID INTEGER
, personame VARCHAR(40)
, jobID INTEGER
);
CREATE TABLE addresses
( addressID INTEGER
, address VARCHAR(80)
);
CREATE TABLE jobs
( jobID INTEGER
, employerID INTEGER
, jobname VARCHAR(25)
);
CREATE TABLE employers
( employerID INTEGER
, employername VARCHAR(50)
, addressID INTEGER
);
UPDATE ((( people AS P
INNER JOIN jobs AS J ON P.jobID=J.jobID )
INNER JOIN employers AS E ON J.employerID=E.employerID)
INNER JOIN addresses AS A ON E.addressID=A.addressID)
SET jobname='Dishwasher'
, employername='McDonalds'
, address='510 Broadway'
WHERE personame='John Doe';
Hope this helps.

Have you even looked at the documentation? The standard documentation for SQL Server (known as "Books On-Line") includes many examples.
From the SQL Server Books On-Line: Create Trigger[^]

Does anyone know how to push a Basic (VBA) module into Access using an SQL interface?
I have:
- A utility I wrote that runs raw SQL commands against an (already existing) Access database. It uses ADODB.
- An SQL file that builds all my tables and indexes.
- An SQL file that builds my views and procedures.
- An SQL file that populates the database.
All I'm missing is a way to programatically (via my utility and a file of commands) push my VBA modules and my forms and reports into the database. Right now I have to manually import them or drag them from the old version to the new version.
Any ideas?

i am creating a basic web application to try and further understand the asp.net that i have been learning in my course..
i have got a month to wait before i get onto the next section of the course and want to get stuck in..
does anyone know.. or could anyone donate some code in the meantime for the following..
i have a basic user sign up webform with ;
first name
second name
email address
band name
password
d.o.b
i eventually want the user sign up to be written to my version of sql server express 2005
so i can have a record of the users and so i can enable users to sign in.. greet them with their name and bandname and then further post any gigs that they wish onto a calender..
i dont know where to start or how complicated a task it actually is.. i think i will also have to create some form of admin for the database to manage and delete records etc..
any advice or help would be fantastic..
but for now i will just keep scouring the web
cheers...

I think this is pretty easy, unless I don't understand what you want to do.
Wouldn't this work?
select * from property
where Extension = 2 And Num_Key = '0196' and
Cast(Substring(Attrib_code,5,5) as bigint) between 00274 And 01189
Hope that helps.
