Hi All,
I am trying to find a solution on gettting records from One database in to another one.So that i can only rely on one database for any information instead of having to login in to two databases.
Any idea will be much appreciated.
Many thanks

You can write a program to do the job, then schedule it using the scheduler (get access to it from Control Panel) to make it run every day at midnight.

Currently I don't have much time to do this. I used the code (that I pointed out in my previous message) in my projects. I only needed to modify a little to solve some Microsoft Access problems. It worked very well.
What you need to do is to build a standlone program to conduct the copy operation, then schedule it using the Windows Scheduler. I can only guarantee that the code to copy tables across databases works well, whether they are of the same type (e.g. both of them are MS Access) or different (can be Oracle, MS SQL Server, MySQL Server, etc).
The hard part, though, is the creation of the table if it does not exist in the target database before the copy operation starts. This, of course, is assuming that you don't plan to create the table(s) by hand. You have to write that part of the program. However, from your description of your project, this problem does not exist. You already have all the tables ready.
I would suggest using C# and ADO.NET to write this program, since it will save you lots of time.

Thanks so much it really works for me.What i want to find out now is How can i make sure that the copy process doesnt copy data already copied when doing it on another session.
If the copy is done onece during the second operation will it know what records to add?
How do you also solve the problem when the two databases run in Different virtual private networks?
Lastly,when you copy the data it doesnt really check what has been copied before.So all the information will be be copied again every time the code runs.
Many thanks

I am looking for a way to derive a weighted average from two rows of data with the same number of columns, where the average is as follows (borrowing Excel notation):
(A1*B1)+(A2*B2)+...+(An*Bn)/SUM(A1:An)
The bold part reflects the same functionality as Excel's SUMPRODUCT() function.
My catch is that I need to dynamically specify which row gets averaged with weights, and which row the weights come from, and a date range.
|
|
|
|
|
Do the whole thing in a stored proc.
Create a temp table to hold the interim calculations and then do your processing on the temp table (table var in SQL Server). Your design seems a little odd if you hold both the values to be averaged and the weighting factor in the same table.
Row_number() is very useful in this type of processing.

If I have understand your requirement, then try this
SET DATEFORMAT dmy
declare @tbl table(A int, B int,recorddate datetime,KPI varchar(50))
insert into @tbl
select 1,10 ,'21/01/2009', 'Weighty'union all
select 2,20,'10/01/2009', 'Tons Milled' union all
select 3,30 ,'03/02/2009', 'xyz'union all
select 4,40 ,'10/01/2009', 'Weighty'union all
select 5,50 ,'05/01/2009', 'Tons Milled'union all
select 6,60,'04/01/2009', 'abc' union all
select 7,70 ,'05/01/2009', 'Weighty'union all
select 8,80,'09/01/2009', 'xyz' union all
select 9,90 ,'05/01/2009', 'kws' union all
select 10,100,'05/01/2009', 'Tons Milled'
select SUM(t1.A*t2.A)/SUM(t2.A)Result from
(select RecordDate,A,B,KPI from @tbl)t1
inner join(select RecordDate,A,B,KPI from @tbl t)t2
on t1.RecordDate = t2.RecordDate
and t1.KPI = t2.KPI
Hope this helps

hi,
at oracle db i want to backup a row when an update request come for the row. how can i make this with pl/sql?
|
|
|
|
|
use Update Trigger.
Whenever the row is updated use :old and :new objects to get the data from updated row and new row.
If it is after update trigger, you need to use :old to get old values otherwise use select from table to get the value.
Now insert them to the log table. For instance :
CREATE OR REPLACE TRIGGER orders_after_update
AFTER UPDATE
ON orders
FOR EACH ROW
DECLARE
v_username varchar2(10);
BEGIN
-- Find username of person performing UPDATE into table
SELECT user INTO v_username
FROM dual;
-- Insert record into audit table
INSERT INTO orders_audit
( order_id,
quantity_before,
quantity_after,
username )
VALUES
( :new.order_id,
:old.quantity,
:new.quantity,
v_username );
END;

Hi,
Would you know why parameterized queires in a MS Access 2000 DB can't be seen from VS 2008 Report Wizard or Crystal Reports 2008?
When I try to create the report using their wizards, none of them see or detect any queries that use parameters, they only pick the ones that have no parameters at all.
The queries are fully functional, and I am able to invoke them from code.
Thanks for you assistance.
Cheers!

Hi All,
In MYSQL
1)we migrated one project from Oracle to MYSQL.
There is one Procedure that is called by many other procedures.
We will call the procedure Level2 (Called Procedure)
The Level1 (Calling ) Procedure is calling the Level2 Procedure.
If something Fails in Procedure2 - Level2 (.. Called Procedure );
Any other statements in Level1 Procedure before calling proc level2 - should be rolled back since autocommit=0; In Oracle this works fine. Can some one tell How to implement the same in MySQL - Innodb. Or do we have to use falcon for the same.
(In MySql as soon as we call the Level2 Procedure in Level1 - In Level2 procedure there is begin and due to this begin the previous trnasactions are commited )
Details :
Table T
DROP TABLE IF EXISTS `bestr`.`t`;
CREATE TABLE `bestr`.`t` (
`c` binary(3) DEFAULT NULL,
`Col1` varchar(45) NOT NULL DEFAULT '',
`Col2` varchar(45) DEFAULT NULL,
`LCT` datetime DEFAULT NULL,
`DeleteFlag` varchar(1) DEFAULT NULL,
PRIMARY KEY (`Col1`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
Insert into t Values ('1', '1', '1', CURRENT_TIMESTAMP, 'N');
Insert into t Values ('1', '2', '1', CURRENT_TIMESTAMP, 'N');
Insert into t Values ('1', '3', '1', CURRENT_TIMESTAMP, 'N');
-------------------- Proc 1 ---------
DELIMITER $$
DROP PROCEDURE IF EXISTS `bestr`.`lEVEL1` $$
CREATE DEFINER=`BESTR`@`%` PROCEDURE `lEVEL1`(
INO varchar(26),
Out R2 Int,
Out RC Int
)
Begin
Declare R1 Int;
Set AutoCommit=0;
Set R1=0;
Set R2=0;
START TRANSACTION ;
Update T Set COL2 = Col2 + 1 Where COL1 = INO;
-- Block1
Call Level2 ( INO, R1, RC);
Set R2=R1;
-- Block 1 end (Note if Block 1 is commented the transaction is implemented properly.
-- Set R2= ROW_COUNT();
if R1 > 0 then
Commit;
else
RollBack;
end if;
end $$
DELIMITER ;
========================================================
DELIMITER $$
DROP PROCEDURE IF EXISTS `bestr`.`lEVEL2` $$
CREATE DEFINER=`BESTR`@`%` PROCEDURE `lEVEL2`(

)
Begin
Set AutoCommit=0;

Rollback ;
end if;
end $$
DELIMITER ;
==========================================================
---------------------------------------------
Call Level1 ('3', @R1, @R2);
Select @R1, @R2;
2) Is reliable, tested falcon Download link is available?
Your inputs will be very useful.

I am having to build queries on a new database through an ODBC (our company just bought new POS software) to do reports. One of the DBA's at the company showed me how to access some of the data in MS Access. I am trying to do the equivalent in SQL (We are using MS SQL 2000 and do not need an upgrade for what we use it to do).
The first query is this:
SELECT TICKET.[TICKET-STORE], TICKET.[TICKET-ACCT-MANAGER], TICKET.[TICKET-TYPE], TICKET.[TICKET-CONTRACT-DATE], TICKET.[TICKET-NEXT-DUE-DATE], TICKET.[TICKET-LAST-PAID-DATE], DateDiff('d',Now()-1,[TICKET-NEXT-DUE-DATE]) AS Expr1, TICKET.[TICKET-TICKET-NBR]
FROM TICKET
WHERE (((TICKET.[TICKET-TYPE])="O")); Which is named qryactive. Then all of the other queries select from qryactive. My question is - Is there any more efficient way in MSSQL other than building a table out of that query then selecting from it?
The second is the use of TRANSFORM in MS Access. There is not an equivalent in MSSQL 2000. I read a few articles on how to possibly do it, but I get lost.
Could someone point me in the right direction?

1) A more efficient way to handle the query based on the results of another query is to build a MS-SQL view. In your case I belive the view would be equal to "qryactive". The other queries would reference this view just like a table in the "from" clause.
2) I believe the equivalent to TRANSFORM would be PIVOT in SQL-Server. However, I'm not 100% sure that PIVOT is available in SQL 2000.

Hi,
I developed a small website using express edition and MS SQL server 2005(sql server management studio express). Now iam planning to host the application.To publish website with express edition is possible?
What is difference between Proffesional and standard editions of visual studio?
To publish a website standard edition is enough?
And now coming to SQL server whether licensed key is required?
Thanks in advance

AFAIK sql server express can be freely distributed. Just you need to create a setup application and execute its installer from your program.

By using the below query I can get weekno and StartdayofWeek but I need to insert/update these values in respective columns in the original table. Can any one help me.
Select BugDate,
DATEADD(wk, DATEDIFF(wk, 6,[BugDate]), 6) as startdayofweek,
Datepart(wk,[BugDate]) + ((Datepart(year,[BugDate]) - 2008) * 52) as WeekNumber
from [BugsDB_DefectVolume]
Table:
ID BugDate Weekno BugNo StartDayofWeek
111 2009-04-12 NULL 3 NULL

hi,
if both table having unique column,then u can use below query

from dbo.MyTable
join anotherDB.dbo.OtherTable ot
on MyTable.KeyColumn = ot.KeyColumn
|
|

|
|
sorry there is no other table. We have only one table called "BugsDB_DefectVolume". In that single table we need to update weekno and Startdayofweek using Bugdate column...
