Write To Excel Destination Component With Specified Range

Apr 24, 2008

I have an SSIS package that produces an Excel output file say File1
The Excel output file is created from a previous script task by copying a standard excel template to File1
after the copy, File1 has the disclaimer, legend etc... and a header row at row 10.
So data rows should only start at row 11.

I was googling and found that people who read Excel file using an Excel source component have been successful reading
from a range by the use of the OPENROWSET property. It is said to set this property to Sheet1$A5-B999
to start reading from row 5.

I tried to set the OPENROWSET property to be Sheet1$A11-B999 but am getting an error "Check that object exists"
(Sheet1 does exist) So I guess it is the range that has an improper syntax or something else is wrong.

Please advise. Thanks

Write Value From Script Component To Variable (Datatype Object)

May 8, 2008

Hi,

I have a script component that contains a script similar to that shown below;


Public Sub Main()

Dim sqlConn As New SqlConnection("Server=myserver;Database=mydb;Trusted_Connection=True;")

Dim SQLStmt As String

SQLStmt = "select top 10 CountID from mytable"


Dim sqlComm As New SqlCommand(SQLStmt, sqlConn)


sqlConn.Open()



Dim r As SqlDataReader = sqlComm.ExecuteReader()
While r.Read()


Dim MyValue As Integer

If r("CountID") IsNot DBNull.Value Then

MyValue = CInt(r("CountID "))



' HERE I WANT TO WRITE MyValue TO A PACKAGE VARIABLE AS A ROW

End If


End While

r.Close()
sqlConn.Close()

Dts.TaskResult = Dts.Results.Success

End Sub


Once i have a value assigned to MyValue, I want to write this as a row to a variable (DATATYPE Object Value VALUE System.Object) in the package which will be an ADO Recordset Destination that i can then loop through later.

Many thanks for any help

Use Of A SSIS Variable Of Type “Object� Inside Script Component And Task Component

Mar 16, 2007

In a Data Flow, I have the necessity to use a SSIS variable of type €œObject€? inside Script Component and assign to it the content of 'n' variables of string type.
On exiting from the script the variable of type object should contain something like in the following lines:
AAAAAAAAAAAAAAAAAAAAAAAAAAAAA
BBBBBBBBBBBBBBBBBBBBBBBBBBBBB
CCCCCCCCCCCCCCCCCCCCCCCCCCCCC
DDDDDDDDDDDDDDDDDDDDDDDDDDDDD
€¦€¦€¦€¦€¦€¦€¦.
€¦€¦€¦€¦€¦€¦€¦.
On exiting from the data flow I will use the variable of type Object in a Script Task, by reading each element in a cyclic fashion.
Is there anyone who have experienced something like this? Could anyone provide any example of that?
Thanks in advance!

A Custom Component For Use As A VIEW In SSIS- Is It Possible To Create One MERGE Like Component With More Than 2 Inputs

Aug 13, 2007

Hi all
I'm into a project which uses a lot of views for joining 2 or more tables. Using the MERGE component in SSIS will be a huge effort coz it only has 2 inputs and I gotta SORT the input too.
Isnt it possible to have a VIEW like component that joins more than 2 tables and DOESNT need sorting??
(I've thought about creating views in database engine but it breaks my data floe in SSIS and is'nt a practical solution)

Reference To Preceeding Component From Custom Dataflow Transformation Component

I am writing a custom dataflow transformation component and I need to get the name of the preceeding component.

I have been trying to find a way to get a reference to the Package object, MainPipe object or IDTSPath90 object (connecting to the IDTSInput90 of my component) from my component because I think from there I can get to the information I want.

Does anyone have any suggestions?

Serious Script Component Bug - Clears Out All Code Inside Component

Nov 27, 2007



No idea where this bug crept in from. Have been using SSIS for 1.5 years now without hitting this problem.

I had a script component opening an XML document and parsing it using XPATH. I added some code that uses StreamReader / Streamwriter (closing one stream before starting the other). The code works without issue in my C# app.

And it ran without issue 2-3 times in SSIS. Then suddenly after running my package again, the script component says it completes successfully, yet nothing happens. I set a breakpoint on the first line of code - it never hits it. I add a msgbox as the first line of code - and it never displays.

I then close my package / exit out of ssis ... and then re-open it. When i open my script component, all of my code is GONE. All references that I added are gone.

I tried adding the streamreader/writer process to a dll I created from my c# app ... and added the DLL to the package -- same result.

I can reproduce this on 2 different computers.

Anyone experience this problem ? Any idea how to stop it ? Or debug it ?


Here is a slimmed down code sample of what causes the error :


Public Class ScriptMain
Public Sub Main()
Try
Dim xmlDoc As New XmlDocument
xmlDoc.Load("c:ulkasync_86281519_20070628045850225_4.xml")
MsgBox("xmlLoaded") --this doesn't display once the package starts "acting up"
Catch ex As Exception
MsgBox(ex.Message)
UpdateXML("c:ulkasync_86281519_20070628045850225_4.xml", ex.Message)
End Try
Dts.TaskResult = Dts.Results.Success
End Sub
Private Sub UpdateXML(ByVal fileName As String, ByVal message As String)
Try
Dim invalidChar As String = message.Trim().Substring(message.Trim().IndexOf("0x"), 4)
Dim rd As StreamReader = New StreamReader(fileName)
Dim xml As String = rd.ReadToEnd()
Xml = Xml.Replace(invalidChar, String.Empty)
xml = xml.Replace("", String.Empty)
xml = xml.Replace("<![CDATA[<![CDATA[", "<![CDATA[")
xml = xml.Replace("]]>]]>", "]]>")
MsgBox("replaced")
rd.Close()
Dim wr As StreamWriter = New StreamWriter(fileName)
wr.Write(xml)
wr.Close()
Dim xdoc As XmlDocument = New XmlDocument()
xdoc.Load(fileName)
Catch ex As Exception
UpdateXML(fileName, ex.Message)
End Try
End Sub
End Class

Backup Master Key, Cannot Write Into File 'c: Empmaster'. Verify That You Have Write Permissions, That The File Path Is Valid.

Jul 12, 2006

Hi,



I tried to backup the master key by the following syntax :

OPEN MASTER KEY DECRYPTION BY PASSWORD = 'mypassword'

BACKUP MASTER KEY TO FILE = 'c: empmaster' ENCRYPTION BY PASSWORD = 'mypassword'

but it failed and i got the following message:

Cannot write into file 'c: empmaster'. Verify that you have write permissions, that the file path is valid, and that the file does not already exist.

NB: I am using the "sa" user to execute this command.

I know that we have a security permission issue , but where and how ?

Small Problem

Jul 20, 2005

HelloI have a case where Partners are some kind of Super-Users and arestored in a SQL Server database. Best is IMO to put both in the sametable:table Customers:CustomerID[pr.key][blabla]PartnerIDBut of course I have to reference the partnerid from another table andI want SQL Server to maintain the integrity rules. I could splitCustomers en Partners into different tables, but that would not bewise i think.Or I could just reference the CustomerID from the other table and-know- that we are talking about a partner, but in that case it itpossible to reference a customer that is not a partner, and i want toavoid that.Any ideas?Freek Versteijn

Small List Of How Do I's

Nov 27, 2007

Consider a recordset consisting of
Vendor, Invoice, InvAmt, Item,ItemAmt
1, 'A12345', 100.00,'Item1', 25.00
1, 'A12345', 100.00,'Item2', 50.00
1, 'Z22222', 200.00,'Item1',100.00

1, 'Z22222', 200.00,'Item3', 50.00
2, 'A12345', 300.00,'Item4,' 250.00

I have a report that groups by vendor and then by invoice within a vendor.

I want to create a report totals that contains

Number of vendors=2
Number of invoices=3
Total Inv Amounts=600.00
Total Item Amounts=475.00


How?
Number of vendors is =count(distinct vendors) ??
Cant do that for # Invoices because of possible duplicate invoices used by different vendors.
How do i get the total invamt? Each occurrence of the invamt fld is in a list2 as =first(invamt).
I really need the sum of each first(invamt).

Thanx Up Front.

Small Version?

Jun 18, 2007

I currently use JET 4.0 as my database in a small app I distribute. SQL Server Express is way way too big to distribute. I am looking to move to a better database.

Is there a version of SQL that gives simple database CRUD support, but is super small to distribute? I am also considering Firebird as it's a full database and only 3MB on the client as an embedded tool.

SQL Or Access For A Small Forum

Jan 18, 2004

Hi,

I'm just about to launch a forum, and right now its built in ASP classic with an Access db. I origianlly used Access because most hosts charge extra for MS-SQL server. Recently I switched to Jodohost who offers Access, MS-SQL and MySql for at no additional cost. So now that I have the option, I would like to pick the best solution before I launch.


* My questions are...

- What is the best db solution to go with for a currently small forum?

- How problematic do you think a data migration would be in the future if I stayed with Access for now and upgraded to MS-SQL with a full forum?

- Is it just smarter to go with MS-SQL now, with an empty forum, regardless of any preformance issues because potential migration problems are a greater risk?

- At what point does the speed of MS-SQL at high volumes over come the potential lags in accessing MS-SQL if it is hosted on a different machine from the one hosting the webpages?



* And please keep in mind...

- I have no db training. I can muddle through Access well enough, but administrating MS-SQL I think might be another story

- This fourm will start off very small, but could grow to be quite large

- I may not stay with jodohost, and would therefore likely have to pay more for MS-SQL (which I woudl rather not do)

Hello, could someone pls help me with this table design.

I have a project table and a code table. The code table has things like priorities (High, Medium, Low).

Now, I want all projects to be able to use these 'global' codes as well as define their own. So, they could define their own priority code 'Critical', that only their project can see.

Please Help With This View - Small Modification

Nov 17, 2005

I have listed a view below and a portion of the result set that is returned when I run the code in Query Analyzer.  This is part of a timesheet application that logs hours per SCHLSTUID per SECTIONID per week.  This returns the SCHLSTUID(user's ID), SECTIONID, Date that the week starts, the first date that time was logged.  The user could be in several SECTIONID's for the same week.  I need to modify this so that it returns the date that the first time was logged for any of the SECTIONID's per week.  I know that this is probably something simple that I'm overlooking but I just can't get it to work correctly.Example:  SCHLSTUID   SECTIONID   ATTSTARTDT                     FirstTimeEnteredDOn601868445      EN4AR001      2005-09-18 20:59:21.120    2005-09-19

Timing Out On Small Update

I am trying to run a program that works on another site but with a copy of the database(SQL6.5) and the vb front end I keep getting a timeout error.

The vb bit is trying to run an update statement on a table with just over 2000 rows. I cannot amend the vb side because this is an .exe

Is there something I might not have done on the server that could be causing this not to work, i.e configuration issues, bigger logs

Massive TRN File, But Small DB

Apr 5, 2006

Hi Everyone,

We have a large and active MSSQL 2000 database. Recently, after a rebuild of the server, we had a problem with the SQL service SQLSERVERAGENT. The service could not start as the service account lost local permission to the registry. During this time, all of the data being sent to the database from our application accumulated into the database .ldf file. By the time we were able to get the service restarted, our .ldf file was approx. 28 Gigs. When the service restarded, the .ldf file shrunk down to regular size,about 40 megs, and the .trx tlog file grew up to 28 gigs for that specific period (new file every hour).

The problem is, the database file (database.mdf) stayed about the same as it was before the service was restarted. When the .ldf transfered to the .trn none of the 28 gigs of data got stored in the database. What does this mean? Perhaps with the service stopped the application using the db saw problems and did not commit the data making it all useless? Or is it possible that the data in the .trn log just needs to be forced to commit to the .mdf???

Is there any way to verify the data in the 28 gig .trn file and figure out if we should get it stored to the database? If yes, how would we go about verifying it, and after that how would we force it to commit to the .mdf file? Am I on the right track here or is it not as I see it??

Thanks!
Mike

Small Question About BIT Columns

Jun 17, 2004

1-8 bit columns in a table consume one byte of storage space. That sounds simple and efficient.

If a bit could only store two values, this would make sense. But, a bit can be one of three values: NULL, 0, 1.

How does a NULL-able bit column only consume the storage space of a regular 0/1 bit?
