Re: Login Problem in sql server 2008 r2

Not enough information!

Use SQL credentials - user id and password registered in SQL server, do NOT use integrated security.

Create the user for your app in SQL server eg userid - MyAppUser
Give the user dbo rights to your database
Use those credentials in your connection string.

If this does not make sense to you then get a book or an article and work through the examples.

How to create data copies SQL Server 2005 Express ?

Re: How to create data copies SQL Server 2005 Express ?

Case 1:
Suppose there are two computers (Ser1, Ser2) and SQL Server 2005 Express is installed on each machine, the input will be stored on the machine Ser1, if the data changes on the computer Ser1 will be updated again computer Ser2, the ask my SQL Server 2005 express can update data on the computer Ser2 from Ser1 ? How the computer config ?

Case 2:
Suppose there are two computers (Ser1, Ser2) and SQL Server 2005 Express is installed on each machine, the input will be saved to Ser1 or Ser2, meaning that if the computer Ser1 busy, it will save computer Ser2 or else, and 2 machine Ser this is always synchronized data.

if I understand this issue I find the document what ? or what keywords to search on google.com?

I do not get through formal classroom training school, not knowing I ask you help, if you are not only helping out loud, do not know without question, the more bites.

And english is not your first language, I understand that. However the results of the search I supplied will give you more information and better resources than a forum post. Your requirement is not ~~trivial~~ small.

SQL Server 2005 Express cann't create Replication\Local subcriptions ? because sql warning: Microsoft SQL Server Management Studio is unable to access replication components because replication is not installed on this instance of SQL Server. For information about installing replication, see the topic Installing Replication in SQL Server Books Online.

I would not expect replication to be available in an Express version as it is one of the advanced features of the database but I don't know as I use neither the Express nor do I need the replication features.

Change cursor to common table

21-Dec-14 17:01

I configure SQL Server Merge Replication, when merger database together, if one of the two server machines damaged or die, the software did not transfer it, i have to manually reset ip to the software to run, how to automatically switch to 1 in 2 server fails ?

How can I change the below code snippet from using cursor to using table expression. The below code is about getting specific data for general account and all accounts below such given account

FUNCTION [dbo].[GetChildrenAccount] 
(@AccountID INT, 
 @DateFrom DATETIME,
 @DateTo DATETIME,
 --@TypeTransaction INT,
 --@Currnecy INT,
 @Branch INT) 

RETURNS DECIMAL(18,3)
     AS      
BEGIN 
    
DECLARE @Account_ID AS BIGINT,
        @IsLeaf AS BIT,
        @TotalValue AS DECIMAL(18,3),

SELECT @TotalValue = ISNULL(SUM(JournalDet_Debit),0) * CASE WHEN @Currnecy = 0 THEN AccountBranch_CurrencyConv ELSE 1 END
FROM AccountTree 
INNER JOIN Account_InBranch ON (AccountBranch_AccountID = Account_ID)
LEFT JOIN Journal_Details ON (Account_ID = JournalDet_AccountID) 
LEFT JOIN Journal_Head ON (Journal_ID = JournalDet_HeadID)
WHERE (Account_ParentID = @AccountID OR Account_ID = @AccountID )
AND Journal_BranchID = @Branch 
AND Journal_Date >= @DateFrom AND Journal_Date <= @DateTo
GROUP BY AccountBranch_BegBalDebit , AccountBranch_BalanceDebit , AccountBranch_CurrencyConv

OPEN GetAccount_ID      	      
	FETCH NEXT FROM GetAccount_ID INTO @Account_ID      
	WHILE @@fetch_Status = 0      
	BEGIN      
	SET @TotalValue = @TotalValue + dbo.GetChildrenAccount(@Account_ID,@DateFrom,@DateTo,@Branch)
	FETCH NEXT FROM GetAccount_ID INTO  @Account_ID     
	END      	      
	CLOSE GetAccount_ID      
DEALLOCATE GetAccount_ID  	

RETURN ISNULL(@TotalValue,0)
END

You seem to be missing the definition of your GetAccount_ID cursor.

I removed some parts of the function when posting may be I forgot and remove the declaration for

GetAccount_ID

and here is the declaration

SQL

DECLARE GetAccount_ID  CURSOR STATIC FOR
SELECT Account_ID FROM AccountTree WHERE Account_ParentID = @AccountID AND Account_Isleaf = 0

It's tricky to answer without your table definitions and some sample data, but this should get you close:

SQL

WITH cteAccountTree As
(
    SELECT
        @AccountID As Account_ID

    UNION ALL

    SELECT
        P.Account_ID
    FROM
        cteAccountTree As P
        INNER JOIN AccountTree As C
        ON C.Account_ParentID = P.Account_ID
    And
        Account_Isleaf = 0
)
SELECT
    @TotalValue = IsNull(Sum(JournalDet_Debit), 0) * CASE WHEN @Currency = 0 THEN AccountBranch_CurrencyConv ELSE 1 END
FROM
    cteAccountTree As T
    INNER JOIN Account_InBranch As B ON B.AccountBranch_AccountID = T.Account_ID
    LEFT JOIN Journal_Details As JD ON JD.JournalDet_AccountID = T.Account_ID
    LEFT JOIN Journal_Head As JH ON JH.Journal_ID = JD.JournalDet_HeadID
WHERE
    Journal_BranchID = @Branch
And
    Journal_Date Between @DateFrom And @DateTo
;

The first part is a recursive common table expression (CTE):
How to use recursive CTE calls in T-SQL[^]

This should return the list of all accounts in the tree which have the specified account ID as an ancestor, excluding any with the Account_Isleaf flag set.

NB: If your tree is particularly deep, you might run into the default recursion limit. There will probably be a way to work around it, but it won't be as nice as the recursive CTE solution. Smile | :)

You then join the tree of account IDs to your branch and journal tables to calculate the total in one hit.

The only part I'm not sure about: your code seems to be double-counting at each level:

sql>SELECT

<hr size="1" color="#63B4FF" noshade="">
  <span style="color: rgba(0, 88, 170, 1)">
    <cite>"These people looked deep within my soul and assigned me a number based on the order in which I joined."</cite>

Thank very much for help. I'm trying to learn about recursive expression table however I cannot know how its really work Frown | :(

The Where clause you mentioned at the end of your post to be able to get the parent account and its child(s) too and that what I forgot to mention in the post because I did not know it at the time when I wrote the post what I need to get is the parent account and its child(s) account(s) and if those child(s) account(s) is/are a parent(s) for another child(s) account(s) I got them too Smile | :)

it seems stupid but this function is used within a procedure to get the balance of the account chart within the system.

Finally, I'm thanking you too much. could you help sending me a link to an explanation of the recursive CTE and how it is implemented

I still think the query you posted is double-counting:

You get the total for account A;
You then loop through the child accounts:
- You get the total for account A.1 and its parent account (account A), and add it to the total;
- You get the total for account A.2 and its parent account (account A), and add it to the total;
Etc.

By the time you've finished, you've added the total for account A multiple times - once for each child account.

From your description, you just want to get the total balance for an account and its descendants, which means that your original query isn't correct.
