Help Needed: For Creating Synchronous Transform Component
Mar 13, 2006
Hi
I am currently trying to write a custom transform componet in c# that will take a row of data, perform a look-up via an external system,
then if there is a match then send the data from the extranel system down macth ouptut (which will have different columns to the input) and drop the data that
was read, else send the data down the unmacthed output which will be the same as the input.
So I would like to write a synchrons transform becuase I don't need read all the rows from the input buffer before I started processing, also I wish have millions of rows
load in memory.
Can this be done? also does any have explame code of how to do this? becuse I can't see how to send data down the match output buffer,
as this will have the lookup results data which will have diffent columns to the input data and how disgard the input data as well.
HI, I need to know whether I am on the last row or not in my script component. If this is the case, I would alter a column in the row that indicates me that I am processing the last row. Is there a way to do it? I tried with process input but when the EndOfRowSet() indicates me that the last row is porcessed, I cannot alter the row in the buffer.
Can anyone please point me in the right direction?
What I am trying to do should be very straightforward:
Take a flat file, perform various transformation on various columns using the SCRIPT COMPONENT task, then send the transformed (and un-transformed) rows to a table in the database.
My question is, how to do this using scripting? I have yet to see an example of what I'm trying to do. (I have both Kirk Haselden's book, Donald Farmer's SSIS scripting book, and the msdn website, but I have yet to see an example of what I'm trying to do!)
FILE SOURCE --> SCRIPT COMPONENT (synchronous transform) --> OLE DB DESTINATION
How do I account for all the columns that will be both transformed and un-transformed, and get them into the table? That is the missing piece of information I can't find anywhere.
The closest thing I found was this code snippet. Do I need to use this syntax, eg. Me.Output0Buffer.FirstName = (where FirstName is the actual column name??)
etc.
Then, once I hook up the SCRIPT COMPONENT to the OLEDB Destination, which uses a connection manager to the table, it will insert FirstName with what I specify?
Wanted to enquire how this is done. Tried doing it in the setUsageType method I have overwritten but only allows description to be changed. Basically need to change "Name".
Best option would be to change it instantly when a user selects a column from the inputs in the custom component, ie. it changes the Output Alias to a desired value. (Input tab in advanced editor)
All this is being done in a custom component which I would like to be synchronous, can achieve a similar result asynchronously.
In my data flow, I am reading addresses from a CSV file. Then for each row, I would like to execute a process from the command line which outputs the latitude and longitude for the address, parse the output, and add the latitude and longitude into the pipeline. To call the process, I am using a script component transform. Here's my code:
Dim m_Latitude As Double
Dim m_Longitude As Double
Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)
Dim street As String
Dim city As String
Dim state As String
Dim zip As String
street = Row.address
city = Row.city
state = Row.state
zip = Row.zip
Dim p As Process = New Process()
p.StartInfo.FileName = "C:\GeoCodeDotNet.exe"
p.StartInfo.Arguments = String.Format("""{0}"" ""{1}"" ""{2}"" ""{3}""", street, city, state, zip)
p.StartInfo.WorkingDirectory = "C:\"
p.StartInfo.UseShellExecute = False
p.StartInfo.CreateNoWindow = True
p.StartInfo.RedirectStandardOutput = True
AddHandler p.OutputDataReceived, New DataReceivedEventHandler(AddressOf ConsoleDataReceived)
p.Start()
p.BeginOutputReadLine()
If p.WaitForExit(10 * 1000) Then
Row.Latitude = m_Latitude
Row.Longitude = m_Longitude
Else
p.Kill()
Row.Latitude = 0.0
Row.Longitude = 0.0
End If
End Sub
Private Sub ConsoleDataReceived(ByVal sender As Object, ByVal e As DataReceivedEventArgs)
Dim output As String() = e.Data.Split(New [Char]() {" "c})
m_Latitude = CDbl(output(0))
m_Longitude = CDbl(output(1))
End Sub
I'm just getting very weird behavior. First of all, at the point where I assign values to Row.Latitude and Row.Longitude, m_Latitude and m_Longitude don't always have valid values (e.g. - they are unassigned). Secondly, after attempting to process the first couple rows, it just stops. In my data flow, the script component is yellow, but execution has ended, and the final step of writing to the output CSV file has not even started. Finally, in the directory where my source CSV file is located, I get a SQL dump file with the following content:
I'm guessing this all has to do with some kind of threading/concurrency thing and how the data flow pipeline works. Could someone please shed some light on this?
By the way, the script component transform is synchronous. Much thanks.
I have a requirement to access a lookup table from within an SSIS Transform Script Component
The aim is to eliminate error characters from within the firstname, lastname, address etc. fields by doing a lookup of an ASCII code reference table and making an InStr() type comparison.
I cannot find a way of opening the reference data set from withing the transform.
Would anyone happen to have any pointers or know of any good code examples to either programmatically change the type of an input column when it is passed through the component, or add a new column to the output? I am extracting data from an Oracle database which is in Julian date format (represented within SSIS as a DT_NUMERIC column) and I need to to either transform the input column holding it into a date column, or to dynamically add a new output column holding the transformed data.
Hi, I have 56 fields coming into the input of an script component, The need for script component was to just to check if one of those 56 columns has a valid date or not, If valid it will parse and put in an output date column, if not, it will put in NULL.
The 55 fields should be passed on. I dont really wanna write code and define output columns. How do I do this ?
I made a Java application to pre-process portuguese texts (stopwords, stemming, BOW creating, etc.)
I want to transform this application on a Integration Service component. I understand I will have to code this new component from zero. But I have no idea on how to start.
I'm reading and testing several tutorials on Integration Services that came with the SQL Server install package but none of them has clues on developing new components. These tutorials seams more focused on demostrate the (awesome) capabilities of Integration Services.
Is there any tutorials on how to implement new components to Integration Services ?
Need help in writing a query. I have a table contains details about an item. Each item belongs to a group. Items have different status. If any one of the item in a group is not "Completed", then the itemgroup is in state incomplete. if all the item under the group is completed then the item group itself is completed. Now I need to create a view with itemgroup and itemstatus. Suppose I have five records
I know the method where you select each and every table and manually create foreign key relationships to other tables in the database visually or by sql. Is there any way in SQL server 2005, to create these relationships using wizard, where it checks for the same column names in different tables and creates the relationships. If yes, please let me know how to do it in SQL server 2005.
Does anyone have any examples of programmatically creating a Transformation Script Component (or Source/Destination) in the dataflow? I have been able to create other Transforms for the dataflow like Derived Column, Sort, etc. but for some reason the Script Component doesn't seem to work the same way.
I have done it as below trying many ways to get the componentClassId including the AssemblyQualifiedname & the GUID as well. No matter, what I do, when it hits the ProvideComponentProperties, it get Exception from HRESULT: 0xC0048021
Does anyone know how to create a Source Script Component programmatically. I can only seem to create a Transformation Script Component. I have this:
PipeLineWrapper.IDTSComponentMetaData90 sourceComponent = ((dataflowTask as TaskHost).InnerObject as PipeLineWrapper.MainPipe).ComponentMetaDataCollection.New();
Hi,I have a need to create a table detailing the ID of all contacts and thelast time they were contacted. This information is stored in 2 tables,'contact' and 'activity' (ID in the 'contact' table links to 'main_contact'in the 'activity' table).I guess I need some sort if iteration to go through each contact and findfind the last activity that took place against each of them (there many bemore than 1 activity against each contact) and then place the output valuesinto the new table.Can anyone show me how to go about this?Thanks!
I am using a poker application that imports all played hands into a PostgreSQL database. I'm trying to write some queries for that database so I can make good use of the data. I figure PostgreSQL and SQL server probably have similar language. And I know these forums are great. So I'm posting here for help.
This is a working code snippet that retreives three properties of a player:
Code Snippet
SELECT sum(totalhands) AS HANDS, sum(vpiphands) AS VPIPHANDS, sum(pfrhands) AS PFRHANDS FROM compiledplayerresults WHERE compiledplayerresults_id in ( SELECT compiledplayerresults_id FROM compiledresults WHERE play SELECT player_id FROM players WHERE playername='PLAYERNAME')); This is all I can do with my skills right now. However I very much want to learn to query for more things: - I'd like to be able to make a query for several players at the same time - I'd like to be able to get the aggregate properties for all players who are not PLAYERNAME1 or PLAYERNAME2 - I'd like to be able to get the aggregate vpiphands property from all players whose totalhandsis > 100 and < 1000.
I hope you can help me with that. If you can, that will make me very happy and grateful! Thanks!
Since installing the client tools for SQL 08 R2 on my laptop, I am running into the following error when trying to open a step within a SQL job:

I had a SSIS Package which was developed on Beta Version Of SSIS, Now We have Standard Edition Of SSIS(Sql2k5) Installed.
In the Package we have One Flat file Source, One Script Component and A Sql Server as Target, We are programaticaly creating the package, Now When we open this Package in the Designer and Try to Run We get this error
"The script component is configured to pre-compile the script, but binary code is not found. Please visit the IDE in Script Component Editor by clicking Design Script button to cause binary code to be generated. "
Now when we just open the Script Designer and close it, The package runs.
I found the Error description at this link http://msdn2.microsoft.com/en-us/library/microsoft.sqlserver.dts.runtime.hresults.dts_e_binarycodenotfound.aspx
but could not find any help on this.
Same thing use to work on Beta version now it is now working. From my understanding the problem is that in beta version, the script use to run at runtime, Now what they have done is that they generate a compiled code out of script and run.
My problem is that since i am using C# code to generate the package, How Will I Create a Binary Code out of Script.

In Report Design view
In "Data" tab, I can see records for column 'sRCName' returned from the stored procedure(usp_GetRouteCodeData) after clicking '!' icon. When I moved to "Preview" tab, I am getting below error message. "The value expression for the textbox €˜sRCName€™ refers to the field €˜sRCName€™. Report item expressions can only refer to fields within the current data set scope or, if inside an aggregate, the specified data set scope."
Observation : there is no value returned from the dataset on 'Fields' panel. The SP is accessing a table called tblRCM. If I go to the Data--> Dataset --> Query, change the "Command Type" from 'Stored Procedure' to 'Text' and entered select * from tblRCM at Query string area, the report is running fine.
Issue: This issue only happens at my laptop, my team member can create the same report using the same stored procedure without any error. The database is sitting on a server.
In the troubleshooting process, I tried to create a simple report by calling a stored procedure(CustOrderHist) from NorthWind DB in my local SQL server, I am able to see the data/value in 'Fields' panel and sucessfully view the data in 'Preview' tab. Looks like the issue only happen on my machine, for a report that using stored procedure to access a DB sitting on a server.
I hope to hear from anyone who have encountered the similiar issue before, or, have any clue to resolve the issue.
I would like to create a database for keeping track of payroll data for employees where the supervisors (job coaches) on our workshop floor can use a Pocket PC device to record the hourly employee data on the fly. Then at the end of the day, the supervisor can place the device in a cradle of some sort and synch the newly entered data into the main database.
I'm guessing that SQL Server Compact edition would be perfect for this type of task? Is that correct? Can someone give me recommendations on how to go about setting this up? What should I use as the main database? SQL Server? Access? Any advice is appreciated!
Превед!Prompt me please some asp.net 1.1 pivote table component that can use both SQL Server database (SQL queries) and Analyse Services database (MDX queries).Thanks.
The following statement is from Microsoft documentation:
If you use the ExclusionGroup property to specify that rows should only go to one or another of a group of outputs, as in the Conditional Split transformation, you must call the DirectRow method to select the appropriate destination for each row. When you have an error output, you must call DirectErrorRow to send rows with problems to the error output instead of the default output.
I have a question about this because I have never used the "ExclusionGroup" property. For example, I have a script component where I specify 4 separate outputs, because I am sending different groups of rows to each output. I accomplish this programmatically using a lot of conditionals and it works fine.
I did not have to use the "ExclusionGroup" property to do this. So I'm not sure why I would ever need this, or to use DirectRow? I'm trying to understand this better, because maybe I feel like I'm not understanding the DirectRow, or how/when to use it.
If you have a data file, and you only want CERTAIN rows to pass to the destination, ie) a table
and you are using a script task to accomplish this,
is this a synchronous or asynchronous transformation?
Q. And how do you assign the values to the output? Do you have to create output columns, or not?
I am very very confused right now. I can't seem to find a decent answer to what is a very basic question either in my SSIS book or in the documenation. Perhaps it is so basic, that the question doesn't seem valid? I don't know. But I just don't understand this at all.
I'm new to SSB, so please bear with me. Our application requirements are: 1) Web app gathers user input from a web UI. 2) Web app calls a stored procedure, passing in the user input gathered in step (1). 3) Procedure issues queries to multiple data sources (SQL Server 2005 db's) derived from the user input. 4) Procedure waits for replies from these multiple data sources, governed by a timeout in case a data source is unavailable or slow to respond.
5) Procedure aggregates the data returned in step (4) from multiple data sources into an XML document. 6) Procedure returns the XML document as an output parameter.
This is different than the usual SSB asynchronous application paradigm. In particular, I'm wondering:
How can I setup a synchronous dialog, where the procedure that issues the SEND waits for a reply from the target service? I don't want the initiator procedure to end after SENDing, but rather wait for the replies to those messages so it can aggregate the data from the reply message bodies.
Hi guys,in my db i have these three tables1.Stores 2.Products3.Partstheir structure is something like :Stores ----Products ----PartsStores----------------StoreId, StoreNameProducts----------------ProductId, StoreId, ProductNameParts----------------PartId, ProductId, PartNamenow, in my application i wanna to implement a bulk-copy operation souser can copy products from one store to another one and when aproduct copied to new store;all of it's parts should copy too.in fact i need a method to insert a Product item in Products table andsynchronously copy it's parts into Parts table and repeat this stepsuntil all of proucts copied.how can i do that without cursors or loops ?Thanks
I have synchronous mirroring. Some times I loose connection to witness and mirror servers. These times primary server is down. Is there any way I can change mirroring to asynchronous when primary server is down due to communication break down between witness and mirrored servers? I can break mirroring but to re-establish mirroring, I have to backup and restore on the other side. So if I can change mirroring to asynchronous when primary server is down due to connection breakdown between witness and mirrored server, then when witness and mirror servers come back, I don't need to restore the entire database. Ofcourse I could use asynchronous always but that does not failover automatically. I am thankful to all answers and suggestions. Thanks.
