Let me try to sum up what you need.

1. The field that resets the running balance has to be in every row of the SQL that populates the report.

2. You have to create a hidden textbox on the detail row. It references the field in #1 above. You hide it because you don't want it on the report, it's just a ReportItem we need for referencing elsewhere.

3. In the running balance textbox, you write a call to Code (see above) that has parameters for beginning balance, and transactions (typically divided into Debits and Credits but may be one field), and the field that resets the Running Balance. These parameters typically refer to ReportItems which is why you need this hidden field to reset the report, as well as a balance, debit, credit, etc...).

4. In Report, Report Properties, Code tab, you put the code (similar to above posting) but only with parameters that match what you put in #3. Your parameters in 3 and 4 may not match my parameters above--make parameters that match your situation. Your mileage may vary. 🙂

5. The field that resets the balance may be a string or a different data type. Fix my code accordingly.

6. If you're getting an error, you probably don't have matching parameters in 3 and 4 or you have a bad reference/typo.

Sample Code:

dim RBalChanger as Short

dim Balance as double

dim Counter as integer

And in the code:

Function CalcSubTotal(BegBal as double, Debits as double, Credits as double,BalChanger as Integer)

If RBalChanger <> BalChanger

Balance = BegBal + Debits + Credits

Else

Balance = Balance + Debits + Credits

End if

Counter = Counter +1

RBalChanger = BalChanger

Return Balance

End Function

Sample Call from Textbox:

=Code.CalcSubTotal(ReportItems!txtBegBal.value,ReportItems!txtdebit.value,ReportItems!txtcredit.Value, ReportItems!txtBalChanger.value)

I hope that this has simplified things for you. I'm on vacation next week and out of town but may be able to look at code today.

All of the methods used where a correlated sub-query uses the < or <= relationship is doomed to performance failure. If you want a very high speed (1 million rows in 7 seconds) method for doing this, I recommend you take a look at (study and try, actually) the following article...

http://www.sqlservercentral.com/articles/Advanced+Querying/61716/

I've used the method with great success and it's never failed me.

Well, I have to say you're right. I tested over 300,000 rows and the report is taking way longer to run than the pure SQL. The reason I did it this way is that my coding skills are stronger and I couldn't figure out a SQL Server solution AND because I'd used code in Reports before. Guess I need to look at your article closer (it's pretty complex) and apply it to my project. Thanks for pointing this out.

Hi,

I'm getting this warning when I run the report:

"Warning1[rsRuntimeErrorInExpression] The Value expression for the textbox ‘Running_Balance’ contains an error: Input string was not in a correct format.e:\ad-hoc report generation\reporting services applications\banking reports\banking reports\SL_2.rdl00"

In running balance textbox, I'm writing following :

=Code.CalcSubTotal(ReportItems!GLCrDr.value,ReportItems!debit.value,ReportItems!credit.Value,"rs",1,CInt(23))

It is showing UnrecognizedIdentifier in CalcSubTotal.

Why is this error appearing? Please look at the image.

Hi,

Can you please explain me what shall I pass in RBalChanger parameter?

I don't have such field.

You bet... and thank you very much for the feedback. 🙂

I'm getting this warning when I run the report:

If you create a stored procedure to return a result set using the methods in the following article (mentioned previously on this thread), no such problems will exists and you will have very high speed running totals, to boot... 😉

Hi Jeff,

I have visited the link. I've to look in to detail for your solution. I'll try and let you know.

Thanks for your help.

I'm back from vacation and working on this code again. I'm hung up on creating (or recreating?) the indexes. Here's a piece of my code. The error I get is "Incorrect syntax near ')' ". The cursor is on the 2nd line of the 2nd index but the line number it's referring to is in the CREATE TABLE statement on the ",credits decimal (18,2) NOT NULL " line. Any thoughts? This table and indexes will have to be recreated each time the report runs. Thanks.

-- ===== Create the test table

CREATE TABLE [dbo].TransHist

This almost works:

ALTER TABLE [dbo].TransHist

ADD PRIMARY KEY CLUSTERED (RowNum)

CREATE NONCLUSTERED INDEX IX_TransHist_AccountID_Date

on [dbo].TransHist (Account, Acct_unit, sub_account,posting_date)

But when I execute the procedure, it says:

"Msg 308, Level 16, State 1, Procedure Trans_History3_pr, Line 1177

Index 'IX_TransHist_AccountID_Date' on table 'dbo.TransHist' (specified in the FROM clause) does not exist."

It's like the 2nd index is not getting added. I've tried various syntax changes but no luck.

Dunno what's wrong... the code above ran just fine on my box.

Strange, I'm not getting that error this morning. However, it's part of a larger piece of code. First time I run it, fine. Second time it says the table already exists. It is not an object in tempdb..sysobjects, so this stops it the 2nd time.

If EXISTS (SELECT * FROM tempdb..sysobjects WHERE name = 'TransHist' AND type = 'U')

BEGIN

DROP TABLE TransHist

END

gardenlady SSCommitted Points: 1974 More actions · Answer 13

Okay, I found code to get around that. Now it says my nonclustered index does not exist. But when I run my code again, it doesn't add either index and so I get an error:

Msg 308, Level 16, State 1, Procedure Trans_History3_pr, Line 1185

Index 'IX_TransHist_AccountID_Date' on table 'dbo.TransHist' (specified in the FROM clause) does not exist.

Never mind. I got the syntax fixed, it runs and tests correctly. Thanks for the great referral.
