For Loop Expression

Aug 24, 2006

I'm trying to run a data flow task inside of a for loop container.

First I was attempting to set the forloop expressions using variables that I was setting by running execute sql tasks. I ran into so many problems there, I decide to try this an easier way.

So I've created 3 variables, all Int32. One is called counter, one is called inc, and one is called max. The values are set to: counter=1, inc=2, max=100.
I then need to set the Expressions for the for loop. SO I open the properties window, and click on Expressions on the left hand side.

I've set the following:
AssignExpression : @counter = @counter + @inc
EvalExpression : @counter < @max
InitExpression : @counter = 1

To prove to myself that the counter variable was not incrementing, I created a Script Task, and had it show a MsgBox with the latest counter value. It's looping, but the counter variable just stays set to 1.

What is the trick? Once I get this, then I can set these variables to other variables.

Thanks in advance.

For Each Loop / Expression Behavior

Apr 30, 2007

Hello all,



I have a question concerning properties, variables, expressions, and their interactions within a for each loop. I'm still hammering out some details with the SSIS package I have been posting about recently, and I came across this bit of what may or may not be odd behavior (and it may only be odd because it's not doing what I expect).



I have a number of execute sql and script tasks inside a for each container. I am using one of the script tasks to flip a couple of variables on and off that I thought I could use to disable or enable later tasks during run time. What seems to be happening is that when I set disable on those tasks to true, I can no longer run them again in later iterations of the loop.



In other words: I can loop through it three times, with disable set to false via an expression - then the fourth iteration evaluates to true and disables the appropriate tasks, and then any later iterations no longer run any of the disabled tasks whether the expression evaluates true or false. Once disabled, they stay disabled, regardless of expression.



Is this a bug, or is there a "proper" way to do this? Am I foolish to assume that a "dynamic" run-time property is actually changeable with each iteration of a loop?

URGENT - My Error Or Bug? The Result Of The Expression Cannot Be Written To The Property. The Expression Was Evaluated, But

"C:\sql_working_directory\MLS\AZ\Phoenix\Docs\Armls_Schema Updated 020107.xls"

Directly using C:sql_working_directoryMLSAZPhoenixDocsArmls_Schema Updated 020107.xls
as connectionString works

However - I'm trying to deploy the package - and trying to use expression:
@[User::DIR_WORKING] + "\Docs\Armls_Schema Updated 020107.xls"
which causes the same error to occur

(Same error with other Excel source also:

Reporting Services :: Running Value Expression Within Lookup Expression In SSRS?

Oct 28, 2015

I have created 1 report with 2 datasets. This report is attached to the 1st dataset.For example,1st one is "Smallappliances", 2nd is "Largeappliances".

I created a tablix and, the 1st column extracts Total sales per Sales person between 2 dates from 1st dataset (Small appliances). I used running values expression and it works fine.

Now, I would like to add another column that extracts Total sales per sales person between 2 dates from 2nd dataset (Large appliances). I am aware that I need to use Lookup expression and it is giving me the single sales value rather than the total sales values. So, I wanted to use RunningValue expression within lookup table to get total sales for large appliances.

This is the lookup expression that I added for the 2nd column.

=Lookup(Fields!salesperson.Value,Fields!sales_person.Value,RunningValue(Fields!sales_amount.Value,
sum, " sales_person"),
"Largeappliances").

I get this error when I preview the report.An error occurred during local report processing.The definition of the report is invalid.An unexpected error occurred in report processing.

(processing): (SortExpression ++ m_context.ExpressionType)

Foreach Loop Doesn't Loop

Mar 3, 2006

I have a foreach loop that is supposed to loop through a recordset, however it doesn't loop. It just repeats the same row, row after row.

I would like to look into the recordset variable but I can't because it is a COM object and the ADODB namespace is not available in the script task.

Any solution to this? anyone experienced anything similar

Fishing For A Clue. To Loop Or Not To Loop

Jul 8, 2006

I have a table called Tbltimes in an access database that consists of the following fields:

empnum, empname, Tin, Tout, Thrs

what I would like to do is populate a grid view the a select statement that does the following.

display each empname and empnum in a gridview returning only unique values. this part is easy enough. in addition to these values i would also like to count up all the Thrs for each empname and display that sum in the gridview as well. Below is a little better picture of what I€™m trying to accomplish.

Tbltimes

|empnum | empname | Tin | Tout | Thrs |

| 1 | john | 2:00PM | 3:00PM |1hr |

| 1 | john | 2:00PM | 3:00PM | 1hr |

| 2 | joe | 1:00PM | 6:00PM | 5hr |

GridView1

| 1 | John | 2hrs |

| 2 | Joe | 5hrs |

im using VWD 2005 for this project and im at a loss as to how to accomplish these results. if someone could just point me in the right direction i could find some material and do the reading.

Expression Help

Feb 20, 2008



Is it possible to nest expressions within a script in a similar fashion to how they're nested within the expression editor?

I have a requirement to strip trailing digits from a string field, so that only two decimal places are left.

e.g.
1.12345 becomes 1.12
12345.6789 becomes 12345.67

I would do this in the expression editor but I need to use Script component because there are a multitude of conditions that need to be evaluated first which I will do inside a Select Case statement.

I'm wrestling with code that looks like


Newratefield = ratefield.Substring(1, Findstring(ratefield, ".", 1) + 2)

but VB doesn't like the 'Findstring(ratefield, ".", 1) + 2)' part.

Any suggestions on what I can do here?

While Loop

Mar 3, 2008

Hello everyone,I've got this While loop here which is giving me a problem:WHILE (SELECT ProductId FROM _ShoppingCart WHERE CartId = @CartId) IS NOT NULLBEGIN            DECLARE @ProdId int, @ProdSize varchar, @ProdQuan int            SELECT @ProdId = ProductId, @ProdSize = ProductSize, @ProdQuan = Quantity FROM _ShoppingCart WHERE CartId = @CartId                                   If @ProdSize = 'XL'            BEGIN                UPDATE                    _ProductBatches                SET                    XL = '0'                WHERE                    ProductId = @ProdId            END            DELETE FROM _ShoppingCart WHERE ProductId = @ProdId AND CartId = @CartIdEND The problem is that the IF statement isn't being executed. And I know for a fact that 'XL' is ProductSize in my _ShoppingCart database. Whats even stranger is that my delete statement is being executed. So @ProdId is Being set correctly, but when it gets to the IF @ProdSize = 'XL' it doesn't get executed for some reason. If @ProdId is being recognized correctly in my DELETE statement, why is my @ProdSize not being reconized correctly in my IF statement. I checked my _ShoppingCart database, and my ProductSize is definitely 'XL'. Can any one see what could be going on here.  Thank you, Alec

For Loop

Jan 26, 2004

HeaderLoop: for forHeader as curHeader dynamic scroll cursor for
select lngALSHeadrID from "DBA".ALSHEADR where lngFedTaxID>0 do
set AcctNum=lngALSHeadrID;
exec "DBA".sp_ALSHeadr2Policy(AcctNum);
set Cntr=Cntr+1
end for;


The above is the sybase version of a 'for loop' . The query
select lngALSHeadrID from "DBA".ALSHEADR where lngFedTaxID>0 results in 1000 results.
How do I change that in SQL?? Do we have a for loop ??
I checked in BOL but it is confusing with "browse" etc n some other options.

can I write like this?


for { Browse { declare curHeader dynamic cursor for
select lngALSHeadrID from "DBA".ALSHEADR where lngFedTaxID>0 }
set @AcctNum=lngALSHeadrID;
exec "DBA".sp_ALSHeadr2Policy(@AcctNum);
set @Cntr=@Cntr+1
}


I duno its just my guess, can any one help me out. @Cntr and @Acctnum are declared
in the beginnning.

Loop

Mar 13, 2007

hello,
i have this SP to tally up my inventory tables.. im finding a way to loop through my table tblitemdetail to get necessary parameter to be insert into my other SP (SP_StkAdj_tbl_alignmt) that should accept this params (from the itemdetail) :-
@ItemID ='',
@ClientID='',
@CustomLotNo ='',
@UDF1=NULL,
@UDF2=NULL,
@UDF3 =NULL,
@UDF4 =NULL,
@UDF5=NULL,
@UDF6 =NULL,
@UDF7 =NULL,
@UDF8 =NULL,
@UDF9 =NULL,
@UDF10 =NULL,
@StockID ='0950-4388',
@RecvOwn ='OWN',
@ConsignorID ='JAB1MY'
EG:i will GROUP BY my itemdetail so it will give me the x records of data with :-

SELECT ItemID, CustomLotNo, Ownership, ConsignorID, RecvUDF1, RecvUDF2, RecvUDF3, ownerstatus
FROM tblItemDetail
GROUP BY ItemID, CustomLotNo, Ownership, ConsignorID, RecvUDF1, RecvUDF2, RecvUDF3,ownerstatus
ORDER BY ItemID

with the result then, i need to insert the param into the SP:SP_StkAdj_tbl_alignmt so that it perform the calculation.

so i guess this will need some looping from the result set i get from the group by and some Sp calling from main Sp
