Asynchronus Transformation Component

Hi all,

I am missing something simple. I have added a new Transformation Script, put in my code to read the input rows, defined my outputs. I have tried to change the SynchonousInputId to 0, but I only get the option of None or input "Input 0" (91). What have I missed?

Set the SynchonousInputId to None.

The SynchonousInputId of "None" is synonymous with zero (0). The script transformation editor dropdown for the SynchonousInputId changed between service packs between saying "0" in the earlier case, to "None" in subsequent service packs. Both 0 and "None" for the SynchonousInputId property mean, "this is a async script transform".

Assing rows to a table

I have a table where the columns are products and the
rows are customers. It stores sales info by customer and
product. I would like to add a row at the bottom af my
customer list that would be used for totaling each
column. Does anyone know how I can do this?
hi john,
if i understand you correctly you are looking for COMPUTE BY clause of
SELECT statement.
you can check the resultset of following query on northwind database.
use northwind
go
select b.customerid, a.unitprice
from [order details]a join orders b
on a.orderid =b.orderid
order by b.customerid
compute sum (a.unitprice ) by b.customerid
go
if this is not what you want pls post relevent table structure, sample
records, and expected result set out of it.Also specify whether you can
looking for in INSERT /UPDATE/SELECT statment.

Assign T-SQL variables in dynamic SQL statement?

I have a dynamic SQL statement in which I need to assign values to
variables.
SELECT @.querystring = 'SELECT @.rows = COUNT(*)
@.pages = COUNT(*) / @.perpage
FROM utbl' + CAST(@.tableid AS VARCHAR(15)) + ' WITH (NOLOCK)'
EXEC(@.querystring)
This doesn't work as it doesn't assign values to @.rows and @.pages that can
be accessed within the stored procedure.
Any suggestions?
Use sp_executesql with output parameters:
DECLARE @.rows INT
DECLARE @.pages INT
DECLARE @.querystring NVARCHAR(300)
SELECT @.querystring = 'SELECT @.rows = COUNT(*)
@.pages = COUNT(*) / @.perpage
FROM utbl' + CAST(@.tableid AS VARCHAR(15)) + ' WITH (NOLOCK)'
EXEC sp_executesql
@.querystring,
N'@.rows INT OUTPUT, @.pages INT output, @.perpage INT',
@.rows OUTPUT, @.pages OUTPUT, @.perpage
PRINT @.pages
PRINT @.rows

asp.net 2, sql2005, double data rows

I'm stumped. When using the classic asp page, the table produced on the web has 4 rows. But, when using the asp.net 2.0 side against the same stored proc, I get double the rows - 8. However, when I pull from the sql table directly there are only 4 rows. Any ideas? I've looked at this far too many hours...

da = New Data.SqlClient.SqlDataAdapter("pTblTempDisplayInsert2 0,'" & coList & "','" & tblList & "','" & varTblNameT & "'", cn)da.Fill(ds, "myTables")For Each drow As System.Data.DataRow In ds.Tables("myTables").Rows varTxt &= drow.Item("titleID") & "<br />"Next

I get:
1852
1850
2055
2053
1852
1850
2055
2053

If I run the last line of the stored procedure with the variable table name filled in:

SELECT d.titleID FROM ##varTblName d LEFT JOIN xtblTitles t ON d.tblID=t.tblID LEFT JOIN tblStatTitles s ON d.titleID=s.titleID LEFT JOIN xtblURL u ON u.urlID=t.urlID ORDER BY d.tblID, d.[year], d.lineOrder, d.countyID

I get:
1852
1850
2055
2053

If I do a simple select * from ##varTableName, I get four rows...

Thanks,
Janet

First, parameterize your query, then post if you still have an issue.

dim cmd as new sqlcommand("sp_MySP",conn)

cmd.commandtype=storedproc ' not correct property or value, but something similiar

cmd.parameters.add("coList",sqldbtype.varchar).value=colist

cmd.parameters.add ...

cmd.parameters.add ...

da=new sqldataadapter(cmd)

...

Thanks SO much for replying. Okay, here you go... I'm going to show the call to the stored proc from both sides (a test aspx/aspx) the values, and the params for the aspx. Sorry it's so much, but since it works on one page and not the other, I'm obviously missing something...

Thanks for anything you can point to... Janet

Two things I would try, since I'm not seeing it:

Right before your da.fill(ds,"writetables") do ds=new dataset just to make sure the dataset is empty. Then I would try running the following in query analyzer/MMS

EXEC chad.dbo.pTblTempDisplayInsert2 0,(21),(101),harry2
EXEC chad.dbo.pTblTempDisplayInsert2 0,(21),(101),harry2

And see what it returns. Does it return 8 rows in the second resultset?

And then of course, I would run Sql Profiler to see the exact commands the web application is sending and in what order, then I would copy them one by one to query analyzer and execute them and see what is getting returned. I notice you are using temporary tables in your SP's. Is it possible that the data is being added to the temporary tables without being cleared out first?

|||

Well, piss-moan-complain-cheer! The ds=new dataset did the trick.

But, I don't understand it. Just to be safe, I did a search on all the code for "writeTables": the table within the dataset ds. This is the only place that it is used. So, even if the dataset is open from previous placeholder events on the page, this table within the dataset is only used for the first time with the btn click event, so why the doubling?

I'd appreciate your input, I'm new to this, obviously, and would like to try to understand it a bit more... And, I can't thank you enough for taking your time to look at this for me.

Janet
