Hi ,
I can restore my db from SQL server Management with this script;
RESTORE DATABASE [LIDER] FROM DISK = N'E:\OyunTakip\database\LIDER.BAK' WITH FILE = 1, NOUNLOAD, REPLACE, STATS = 10
GO
but i cant do the same thing from C#.
SqlConnection baglantim = new SqlConnection("data source=THORN\\SQLEXPRESS; database=LIDER; integrated security=SSPI");
baglantim.Open();
string cmdText = "RESTORE DATABASE" + " LIDER" + " FROM DISK = 'E:\\OyunTakip\\database\\LIDER.BAK'" + " WITH MOVE 'LIDER' TO 'e:\\Oyuntakip\\database\\LIDER.mdf' " + ",MOVE 'LIDER_Log' TO 'E:\\Oyuntakip\\database\\LIDER_log.ldf'" + ",REPLACE";
SqlCommand komut = new SqlCommand(cmdText,baglantim);
komut.ExecuteNonQuery();
Getting this error ;
RESTORE cannot process database 'LIDER' because it is in use by this session. It is recommended that the master database be used when performing this operation.
RESTORE DATABASE is terminating abnormally.
i cant solve it help pleasEEEe ;(

Change it to
SqlConnection baglantim = new SqlConnection("data source=THORN\\SQLEXPRESS; database=Master; integrated security=SSPI");
That should work.

Getting this error after change LIDER to Master ;
Exclusive access could not be obtained because the database is in use.

Surely you restore into a new database. If the database already exists the restore process cannot work. Try restoring to a database name that does not already exist on the server.
|
|
|
|
|
Execute this command after setting the connection and before restoring the DB
ALTER DATABASE LIDER SET SINGLE_USER WITH ROLLBACK IMMEDIATE;
Of course, the ramifications being that any user connected to the DB will lost connection and any open transactions will be rolled back. It's pertinent for you to check if there are any existing users first, any running transactions first and then do the recovery.

Can anybody guide me as to how do we
call a cursor having rows more than 10000?

I am afraid that you might be running under performance issues when you are working with cursors on a table with more than 10000 rows.
Best bet will be to try populating your records onto a temporary table or table variable.

HI CS,
I GOT WHAT U SAID.
THIS IS MY SCENARIO:
1. PICK UP DATA FROM A TEMPORARY TABLE ROW BY ROW......VALIDATE WHETHER THEY FOLLOW BUSINESS LOGIC OR NOT.
2. IF THE DATA IS ERRONEOUS UPDATE A FLAG IN THE SAME TABLE TO F, ELSE UPDATE IT TO P.

Please don't shout. First of all, can you perform your business logic in SQL? If you can, you can possibly do this without having to use a cursor at all. It's always best to use SET based updates wherever possible, so you could use something like:
INSERT INTO myTable (myCondition1, myValue1, myOtherValue, myValue) VALUES ('...', 1, 2, 'F')
UPDATE myTable mt
SET myValue = 'P'
WHERE myCondition1 = 'Hello' AND myValue1 > 30 AND myOtherValue >
(Select SUM(oValue) FROM otherTable ot WHERE mt.PrimaryKey = ot.ForeignKey) As you can see, the initial insert creates the record and sets it's validity to false. The update is then used later on in your processing to update the records to P that have passed the test.

Hi Manish
What database product are you using?
Note that some databases (particularly SQL-Server), cursors are considerably slower set-based operations. Cursors would only normally be considered for reeeeeeally complex business rules).
Under SQL-Server, if you really have to use a cursor, it would be something along the lines of:
declare c1 cursor for
select field1, field2, etc
from YourTable
for update of MyFlag
open c1
fetch c1 into @Field1, @Field2, @Etc
while (@@FETCH_STATUS <> 0) begin
set @MyFlag = 'P'
--Do business logic checks here - if error then set @MyFlag to 'F'.
update YourTable set MyFlag = @MyFlag
where current of c1
fetch c1 into @Field1, @Field2, @Etc
end
close c1
deallocate c1 The code is similar in other types of databases too.

Andy

You were actually given some valuable help by some one. So why are you angry at the person who has helped you by expressing yourself in 'All Capitals'.

I am extremely sorry if u have mistook my All Caps as being angry.
I was coding the Stored Proc at that time......and as per company standards I had to keep it in All Caps. I am sorry , I forgot to switch it off while typing my problem.
Anyways Guys, Cheerz.
We have found a roundabout way of handling it.
While checking the "select" query was imposing a big chunk, so we have decided to design a tertiary table and use it directly to fetch the records from them. This improved my time around 45%.
What intially took us 2:30 hrs to implement 10 lakh records, is now taking us 1:20 hrs.
Tx guys for all the help u have provided.
Manish Ganguly.

Hello,
I have the following procedure
CREATE PROCEDURE tryproc AS
declare @first int;
select sum(t) as first from demand where product='LPG' AND LOCATION = 'Mumbai';
create table abc (demandsum int);
insert into abc (demandsum) values (@first);
In the above procedure the value inserted in te table is NULL. I want the sum got from the table to be inserted in the table abc.
What must be the problem?

Problem is you are not assigning the variable value. See this and rewrite it
CREATE PROCEDURE tryproc
AS
DECLARE @first INT
SET @first = ( SELECT SUM(t) AS first
FROM demand
WHERE product = 'LPG'
AND LOCATION = 'Mumbai' )
CREATE TABLE abc (demandsum INT)
INSERT INTO abc (demandsum) VALUES (@first) Hope it helps

Hi,
you can use this query ...
however you can reduce the no. of DML stm..
SELECT dem.first INTO abc FROM
(SELECT SUM(t) AS first FROM demand WHERE product = 'LPG' AND LOCATION = 'Mumbai' ) dem
