Hi,
I would like to export a database I use at work to test at home.
I'm wondering if there is a way to export it so the whole database is stored as a file, and you can connect to the file as if it was the SQL server (I cant access the SQL server from home).
Is something like this possible?
I am running SQL Server Management Studio 2005.
Cheers,
Mark Brock

Hi,
you could use the SQL Server 2005 Express Edition at home. It is free to use... Then just create a complete backup at work and restore it at home.

Yes. Use the copy database wizard.

Just run backup...
Run this script in your office computer :
BACKUP DATABASE [db] TO DISK = N'c:\Backup\db.bak' WITH NOFORMAT, NOINIT, NAME = N'db-Full Database Backup', SKIP, NOREWIND, NOUNLOAD, STATS = 10
GO
It will produce an output db.bak in your local C:\backup folder.
[Please replace db with your database name on the script.]
Now in home run this :
RESTORE DATABASE [db] FROM DISK = N'C:\Backup\DB.bak' WITH FILE = 1, NOUNLOAD, REPLACE, STATS = 10
GO
Here db is the name of the database it will create when it restores, place the db.bak file from your office to your home computer in C:\backup or whatever you like to and finally run it..

if you have good internet connection then you can connect remotely as well as by using sql express and their are also so many other Sql Management tools are availbale same like sql server management studio you can use them also and there are some hand tools for sql server datase copying /backup and emailing automatically

while other regular options are their as well as normal backups and copy database , mirroring etc

Means he needs to expose the SQLServer browser from the firewall of the server... This would not be a good option I think.
|
|
|
|
|
if possible then he can add Execption depends upon cicrumstances and is one of the option if possible otherwise there copying or backup is good option and he can even export only some tables and if he can export tables into XML and then can import then it will be even another way to do it , depends upon the nature as far as my understanding is he is not using at clients he is using for his test pc at home

I have following two tables
1st table is Fee:
PK ---- payable
1 ---- 1500
2 ---- 1200
3 ---- 1900
2nd table is Fee_Detail:
pk ---- paid ---- fk_fee
1 ---- 700 ---- 1
2 ---- 400 ---- 1
3 ---- 400 ---- 1
4 ---- 800 ---- 2
5 ---- 300 ---- 2
Result should be
payable ---- paid
1500 ---- 1500
1200 ---- 1100
1900 ---- 0
what is sql query

You need and inner join a group by and a sum
Select FeeID, sum(payable), sum(paid)
from Fee
iner join Fee_detail FD on FD.fk_fee = fee.FeeID
group by
FeeID
|
|
|
|
|
I want to fetch all records of left hand side
and only sum of 'paid amount' matching records of child table(right hand side) according to fk_fee(foreign key column)..
for example
Fee table:
Pk ---- payable
1 ---- 1500
2 --- 700
Fee Detail:
Pk ---- Paid ---- fk_fee
1 ---- 1100 ----1
2 ---- 200 ----1
3 ---- 100 ----1
Result should be
payable ---- paid
1500 ---- 1400
700 ---- 0
|
|
|
|
|
Then you need to use a left join and deal with null values
Select FeeID, sum(payable), sum(ISNULL(paid,0))
from Fee
left join Fee_detail FD on FD.fk_fee = fee.FeeID
group by
FeeID
search here for articles on joins, there is a good one around, sorry I don't have a link
|
|

Below is the query for your requirement. You need to group by each field that you want in the select statement.
SELECT Fee.Payable, ISNULL( SUM(Fee_Detail.Paid) ,0)
FROM Fee Left Outer Join Fee_Detail ON Fee.PK_Id = Fee_Detail.FK_Id
Group By FK_Id, Fee.Payable
Hope it helps you.

You need to be a little more specific and generous with information when asking a question. I would be nice to know what type of control you are using, I will assume a combobox.
Have you tried searching for a solution - this is a VERY common requirement and there are plenty of examples. Basically you bind filter of the city combo to the selected value of the country combo, repopulating the city combo in the onselected index change event.

Something like this:
select * from cities where stateid in (select stateid from states where statename='statename')

Hi dear all,
I am new to database design and database structure, In my internal test i faced one database design problem, tried to solve this but i am still having doubts so please experts give me clear solution for this
Problem is
Media bank is a web application for storing and retrieval of Media files. In Media bank, files are stored in folders (just like in the case of windows). A folder can have sub-folders to any level of depth. A file in a folder can exist either in published or un-published state.
Every folder will have the following information associated with it: folder name and folder description.
Every file will have the following information associated with: file name, file description, physical location in server, size in kbs, type of file.
1. Write a normalized database design for the above mentioned scenario. Also show primary keys, foreign keys, and also what kind of relationship (1-M , M-1 or M-M) exists between them.
2. We add a new feature to Media bank: A file can contain different versions, but only one version will be active at a time. Any version of a file can be set to active by the administrative user.
Modify the database deign above to incorporate this new feature.
3. Write SQL Query to retrieve
a. All files of type ‘images’ with the following information:
File name, File description, state of file (unpublished/published), Folder name, Folder description.
b. All folders with following information:
Folder name, Number of files in published state in that folder
c. All files with following information
File name, complete folder path (all parents until root folder)
Thanks in advance

Hello all!
This seems pretty simple, but I'm still stuck. Probably making it more complicated than it is. I have a tblPot, with Monday, Tuesday, etc as Columns. I need to return the Pot of the week based on todays date.
I'm getting the day of the week from SQL with the DATENAME function. But how can I pass that to match the column name. Basicly I need this simple statement.
SELECT Potname FROM tblPot WHERE Monday = 'true'
How can I get it so it grabs the current day automaticly. Thanks!
Rudy
here is the code
ALTER PROCEDURE [dbo].[SchedPod]
-- Add the parameters for the stored procedure here
@Day nvarchar(50) Output,
@PotList nvarchar(50) OUTPUT
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here
select @Day = DATENAME(dw , getDate())
SELECT @Potlist = PotName
FROM tblPot
WHERE (@Day = 'true')
END
|

Unfortunately the table definition you have makes it quite difficult to get the result you want based on the current day.
However, after saying that there is still a solution to use UNPIVOT.
The idea is to change your day columns (Monday, Tuesday) to a row value, then query the result of the UNPIVOT.
See UNPIVOT[^]

Use a case statement
Select @PotName = Case DATENAME(dw , getDate()) When 1 then MondayCol
when 2 then TusedayCol End
from tblPot

Hi all,
I am trying to hide a table in my report if all the text values are null. I am running the expression =iif(IsNothing(Fields!LoanType.Value), true, false) but this seems to hide the table no matter what. I have also tried the Len function but this doesn't work either. The Table in the database is set to allow nulls for this attribute. Here is an example of two tables I have in the report.
Example dataset1:
Conventional
FHA
VA
null
Expression used:=iif(IsNothing(Fields!LoanType.Value), true, false)
Example Dataset2:
null
Expression used:=iif(IsNothing(Fields!Assumable.Value), true, false)
When I apply the above functions both tables are hidden. However, the table holding example datset1 shouldn't be hidden and example dataset2 should be.

Are you using SQL Reporting Services by any chance?
Use IsDBNull function instead of IsNothing. The null value returned by database is not the same as NOTHING or NULL.
