Re: Change cursor to common table

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

Re: Change cursor to common table

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.

My previous answer had a link to an article explaining recursive CTEs: How to use recursive CTE calls in T-SQL[^]
Google also returns the documentation on TechNet: http://technet.microsoft.com/en-us/library/ms186243%28v=sql.105%29.aspx[^]

Appreciating your help. Thanks very much I will review the function again as I'm not the one who wrote it however I'm trying to optimize a Stored Procedure performance which selects from a lot of tables + calling this function. the last time I executed the procedure it nearly took over 14 minutes without a single result while it was still executing Frown | :(

How can you tell if a SQL Server instance max'ed out bottleneck is Memory?

hi - How can you tell if a SQL Server instance max'ed out bottleneck is Memory? It's on a 8GB box with two processors. Seems CPU ok. Memory max out the whole time while this big SELECT-INTO statement is running. Avg Disk Queue lenght ok - avg below 1.0 so doesn't appear disk/paging is causing problem.

However, fact from Task Manager memory keeps 7 GB out of 8GB over the whole time doesn't mean memory is the bottleneck? Or is it?

The same query runs on another SQL server with double the RAM finishes a few times quicker however.

Any advises? Thanks

Check the configuration on the SQL Server instances to see what the maximum amount of memory is that is allocated to them. I'm don't remember where it is, but that is a starting point.

Do I have to have SQL Server Express installed?

I wanted to add database services to my windows app, but didn't want to use SQL Server, Access or even a DBF file would of been fine.

So the code below works fine, creates a database file, but off the top of your head, will I need to have sql server installed on other client machines?

Dim m_connString As String = "Data Source=(LocalDB)\v11.0; Integrated Security=True;"
        Dim myConnection As SqlConnection = New SqlConnection(m_connString)

        Dim myQueryString As String = _
        "CREATE DATABASE STREAKWAVE ON PRIMARY " & _
        "( " & _
        "   NAME = STREAKWAVE, " & _

        "   SIZE = 10MB, " & _
        "   MAXSIZE = 500MB, " & _
        "   FILEGROWTH = 10% " &

If this code works then you are presumably using SQL CE or similar, which is on the local machine. That is fine as far as it goes, but if you wish to share the database with other clients then you will need SQL server.

Sorry so late;

got wrapped up in a few projects

What a pain in the ?, I got it working finally, and found a 33 meg download for localDB.

But the speed is day and night, 20 secs using the DBF vs 1 sec using localDB

So VS2013 gives you the localDB, my users will have to install it.

Just got it to work, create database, tables, records
make the con strings for that.

Better than the oleDB DBF I was going to use, which took 20 sec to write 49 records.
Finished the switch to localDB this morning.
I have never heard of localDB, but it seems handy for vb.net windows apps.

Need to Truncate a table and populate the rest of the tables

I have a .sql file. the file size is 401MB. i found that a table say 'pauseddetailes' which stores the values and more than 1,00,000 records which has to be archived periodically but it is not. Due to this i couldn't import the file in MySQL , phpMyadmin. i need to truncate the table 'pauseddetails' and then import the rest of the data in the db. This particular table is independent and doesn't have any foreign key constraint.

I tried increasing the value of the upload size , execution time and memory size in php.ini file still didn't work out.

Is there any possible way. Looking for the solution.

Thanks in advance.

This isn't how this site works, we will help you where you are stuck. But we dont supply solutions to a requirement.

But I would suggest you read up on inner joins[^] and left outer joins[^]

the syntax is similar across the different versions on SQL Server.

after you have read these and get stuck please show us your code and try to explain why its wrong and we will help you further.

Can you redesign your Database tables? It has very bad relations and out put. Why you have 3 columns for Color1, Color2 and Color3 .With this Column how can you get your result .

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
