Developing New Task In SSIS

Oct 6, 2006

Hi All:

For making a custom Task in SSIS, is it possible to reuse the existing code base? For e.g. If i need to append some functionalities to LookUp Transform. Can I inherit the lookUp transform class?

Thanks,

Vipul

Developing A Custom Task Using OLE DB Destination Adapter

Jul 25, 2007

I am writing a custom task to import data from delimited files into SQL tables. I use the standard Flat File Source adapter, a custom transformation to add a URN column and a filename column to the data and the standard OLEDB Destination Adapter.



Most of my test data files work fine except for ones with a lot of columns (around 350 columns). I get an error when I call the ReinitializeMetaData() method for the destination adapter.



Q1) Is there a restriction on the number of columns (or data row size) that can be imported into an OLEDB Destination Adapter?

Q2) The reason I use this adapter rather than the SQL Server Destination Adapter is that I need to set the destination table name using a variable. I don't believe I can do this with the SQL Server Destination Adapter. Is this the case?

Q3) Anyone know of a better/alternative way of acheiving the above? One way I have thought of is to create a custom destination adapter using the SQL Server Destination adapter as the base but I'm not sure whether this is a) possible and b) worth the hassle.



Hope someone can help...



Cheers

Nick

BUG In BIDS When Developing SSIS Packages

Feb 1, 2007

There seems to be a BUG in BIDS when developing SSIS packages using the Import/Export Data wizard.

If you use the wizard to import a large number of tables, and then select all the tables, and then choose to delete exisiting data in each table, the PrologueSQL file does NOT get built correctly. Instead of having a

TRUNCATE tablename Go

for each table, it just has a bunch of "Go"s with nothing between them. In the step immediately prior, where you confirm what the wizard will do, it tells you, after each table, that it will delete any existing data...but it doesn't do this.

If, during the wizard, I select each individual table one at a time and tell it to delete existing data, then it will get built correctly, but not if I select them all at once...YET, if I do select the whole block, choose delete existing data, and then select any single table, it shows that table as being set up to delete existing rows.

This is very frustrating when trying to import large numbers of tables.

Am I missing something? or is this really a bug?

Thanks, Jeff

Developing Custom Components By Extending The SSIS Stock Data Flow Components

Sep 7, 2006

Everything I've read says that custom data flow components are built by inheriting from the Microsoft.SqlServer.Dts.Pipeline.PipelineComponent class.

But the stock components such as the Derived Column data flow transformation must each be implemented by their own class. So how do I base my custom components on those classes? The documentation for the PipelineComponent class doesn't list any such subclasses.

Ssis Package Hangs On Script Transformation When Running On One Machine Not Developing Machine

May 4, 2007

Help!
I am using Script Transformation to output a new column as image[DT_IMAGE]
field to store serialized object. In the VB script, the sample code as

Row.serializedobject.AddBlobData ( binaryArrayReturnedFromC#dll )

The package always runs fine on my developing machine and will halt on other
machine at AddBlobData after certain number row records were processed. I am
stuck here. Anyone has any suggestion?

What I need is reading data from mutiple tables in one database and writing
into a single table in another datable. In order preserve all the columns
data, I use input column fields to construct a new object and then serialize
it, and store the serialize data into detination db table. (The object and
serialization function is coming from c# dll.)

Dim b As BusinessLicense = New BusinessLicense()
b.ApprovalDate = Row.approvaldate
b.BusinessId = Row.busid
b.BusinessName = Row.busname
b.NaicsCode = Row.naicscode
b.NaicsDescription = Row.naicsdescr
b.OwnerName = Row.ownername
b.Phone = Row.phone
b.Pkey = Row.pkey
b.RenewalDate = Row.renewaldate
b.StartDate = Row.startdate
b.Suite = Row.suite

Row.serializedobject.AddBlobData(Serializer.Serialize(b)) '''----This is blocking line
Row.infoType = BusinessLicense.TYPE



Both machine is xp with sp2. and standard SQL Server 2005 - 9.00.1399.06

SSIS Task Transfer SQL Server Objects Task And Default Constraints On Tables

Feb 21, 2008



I am using the "Transfer SQL Server Objects Task" to copy some tables from database A to database B including data.

The tables, primary key constraints, Foreign key, data and all transfers nicely except for "DEFAULT CONSTRAINTS" on the tables.

I have failed to find any option in the "Transfer SQL Server Objects Task" task to explicitly say "copy default constraints". So I guess logically it should happen automatically but it doesn't. I hope it is not a bug :-)

Any option anyone knows will help.

Thanks.

SSIS (Integration Services) Transfer SQL Server Objects Task: This Task Can Not Participate In A Transaction

Feb 1, 2007

In short, does the €œTransfer SQL Server Objects Task€? support distributed transactions?

In trying to use a €œTransfer SQL Server Objects Task€? in a container using a transaction on the container. The task is set to support the transaction. It is setup to copy table data from several tables from a non-domain server (sql server 2000) to a domain-based server (sql server 2005). I get an error stating, €œThis task can not participate in a transaction€?.

I am wondering if it means exactly what it says €“ this task in SSIS can€™t participate at all. Or does it mean that it won€™t in this scenario for some reason. I attempted a simple copy of data from mssql 2005 to mssql 2005 (same server) and the task still failed). MSDTC appears to be running properly on my machine and such (I can do a simple distributed transaction across linked server to the 2000 server in Query Analyzer (QA)). Also, MSDTC appears to be working on both servers with distributed transaction query tests in QA.

Here€™s the error info€¦

SSIS package "Development BusinessContacts and Products Migration.dtsx" starting.
Information: 0x4001100A at Copy BusinessContacts Data: Starting distributed transaction for this container.
Error: 0xC002F319 at Copy BusinessContacts database table data 1, Transfer SQL Server Objects Task: This task can not participate in a transaction.

New 2005 SSIS Task: File Properties Task

Nov 7, 2007

A common issue that I run across with clients is they want only want to process a file if it's finished transmitting to the server. This SQL Server 2005 task reads the properties of a file and writes the values to a series of variables. For example, you can use this task to determine if the file is in use (still be uploaded or written to) and then conditionally run the Data Flow task to load the file if it's not being used. You can also use it to determine when the file was created in order to determine if it must be archived.

How Do You Get A Reference To The Task Host In An SSIS Task

Feb 26, 2008

I've created my own posting for this. The original post was here, I apologize: http://forums.microsoft.com/forums/ShowPost.aspx?PostID=2906512&SiteID=1

According to the poster it's not possible. But there has to be some way to do it? Reflection (don't know how)?


I need to get a reference to the task host in an SSIS Task component.

Basically the scenario is this:

I have a custom task I have created. However I would like to validate that the ExecValueVariable is infact a string variable during the validate event of the task. I know how to verify its a string variable. But I can't figure out how to read what the user selected (such as User::Myvariable). The only way I've been able to figure out how to do it, but it only works if you open my custom task UI.

What I did is this:

I've implemented IDtsTaskUI and during the initialize section I wrote:

Sub Initialize(ByVal taskHost As TaskHost, ByVal serviceProvider As IServiceProvider) Implements IDtsTaskUI.Initialize
' Store the TaskHost of the task.
Me.taskHostValue = taskHost
Dim myTask As CustomTask= CType(taskHost.InnerObject, CustomTask)
myTask.myTaskHost = taskHost
End Sub

My Task is named: CustomTask. I have a public variable in my task as follows:

Public NotInheritable Class CustomTask
Inherits Task
Implements IDTSComponentPersist
Public myTaskHost As TaskHost = Nothing

Therefore I pass back the taskhost value to the CustomTask class, and voila I have it.

Problem is, this only works if the custom task calls the initialize method, and this only happens when you open the custom editor.

I then do the validation in my CustomTask class and it works fine, but myTaskHost is null/nothing until you actually open the custom task UI

How do I solve this?

I can get the records out of RECORDS without any problems but I don't know how to set up a query that will pull the last chronological 'OUT' record from my IN/OUT table. Is there a way to do this in SQL?

Developing A Database System

Jul 16, 2013

company is developing a database system containing information about cities, towns, and villages in the country. The number of cities, towns, and villages are in thousands and the database program should allow users to search a particular place by name. Users should also be able to search all places that match a particular value or range of values for attributes such as location or population size. This particular feature is known as a range query.

If the database is meant to support range queries that can return many cities that match the query specification, the entire operation may be allowed to take longer. To meet this requirement, it will be necessary to support operations that process range queries efficiently by processing all cities in the range as a batch, rather than as a series of operations on individual cities.Different indexing methods can be used to perform this operation. What will be your choice if:

a) database is created once and has no change over a period of time

b) database is created once and database is changed over a period of time

Assistance Developing Query

Jul 23, 2005

Good Day;I would appreciate assistance developing a query that I haven't beenable to develop without using a second table. I wish to count thenumber of records that are still open on the first of each month.Each record has an open date and a close date or the close date isnull i.e., the record is not yet closed. I've previously beaten thisby building a table, simply a list of the dates for the first of eachmonth for the next ten years or so, and then selecting values basedupon a date selected from that table. However I'd be happier if Icould do it without the second table. I'd be prepared to accept theMin(Date) for each month as being the first of the month.I've included some DDL statements to build and populate the table ifthat helps. Since the selection is rather small and all the opendates are very close together I think the result will be simply adecreasing count from the month the first record is opened till today.A pseudo code select statement might look likeSelect Min(DateOpened) As DateOfInterest, Count(*) as [Qty Still Open]FROM DetailTWhere DateReceived > DateOfInterest or DateReceived is Null andDateOpened < DateOfInterestGroup by Min(DateOpened)Order by Min(DateOpened)I hope I've explained it sufficiently well.CREATE TABLE [dbo].[DetailT] ([Autonum] [int] IDENTITY (1, 1) NOT NULL ,[QDNumber] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,[DateOpened] [smalldatetime] NOT NULL ,[DateReceived] [smalldatetime] NULL ,)Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('C15788', '06/04/2005 9:35', 07/04/2005)Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('B16091', '06/04/2005 9:36', '07/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('B15001', '06/04/2005 9:51', '08/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('M18696', '06/04/2005 9:56', '06/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('C14969', '06/04/2005 10:05', '10/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('O10091', '06/04/2005 10:08', '12/04/2005')Insert into DetailT (QDNumber, DateOpened)VALUES('D01197', '06/04/2005 10:13')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('H15001', '06/04/2005 10:15', '08/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('J15090', '06/04/2005 10:24', '08/04/2005')Insert into DetailT (QDNumber, DateOpened)VALUES('J01202', '06/04/2005 10:31')Insert into DetailT (QDNumber, DateOpened)VALUES('G01193', '06/04/2005 10:32')Insert into DetailT (QDNumber, DateOpened)VALUES('K01164', '06/04/2005 10:35')Insert into DetailT (QDNumber, DateOpened)VALUES('K01162', '06/04/2005 10:48')Insert into DetailT (QDNumber, DateOpened)VALUES('F01124', '06/04/2005 10:59')Insert into DetailT (QDNumber, DateOpened)VALUES('H01147', '06/04/2005 11:01')Insert into DetailT (QDNumber, DateOpened)VALUES('S15068', '06/04/2005 11:10')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('E12322', '06/04/2005 11:32', '07/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('A12205', '06/04/2005 11:37', '06/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('D12259', '06/04/2005 11:40', '07/04/2005')Insert into DetailT (QDNumber, DateOpened)VALUES('C03394', '06/04/2005 11:51')If you made it this far thank you for your patience.

Sdk For Developing Sql Server Front-end

Feb 1, 2006

I am in the planning stages of a front-end to access sql server databases. The project involves analysis of stored data as well as storing results of the analysis. The classes for the analytical part is fairly complex so I would like to speed up the data manipulation part of the project. I am already familiar programming with ADO but I was hoping for a more complete solution. Is there a sdk or example code (third-party OK) that could facilitate this?

The client is not especially fond of .NET and would prefer to use VB6. However, with the right solution, C# or VB.NET would be acceptable languages.

Programmatically Developing An Entire Package..

Jun 8, 2006

Hi all,

I am trying to write a program that creates packages on the fly depending on the variables you pass. for eg. It should create connection managers on the fly specific to a certain file in the variable (eg. sample.csv). the package has a dataflow task and it has flat file source and oledb destination.The problem I am facing is the flat file source when assigned to a flat file connection manager(dynamically), it is not giving any source output columns. i.e, the value for DFSource.OutputCollection(0).OutputColumnCollection.Count is Zero. But when I use the same code and reverse the source and destination(oledb as source and flatfile as destination), it is working fine. I searched everywhere for resources on how to develop packages programmatically, but could not find any except one example on msdn. If anyone knows about this prob or any useful resources on this subject, it would be really helpful.

Thanks,

Prithvi.

Developing App That Will Use SQL Server Express On Back End...

Hi...

I have the full version of SQL Server installed on my machine and am developing an app using BI DTS packages, VB.Net, SQL SPs, etc.. I will need to deploy this app w/SQL Server Express (SSE).

-Do I have to install SSE on my development machine for the purpose of creating the install package of my application? I am afraid that if I do install SSE on my machine, it may mess up my installation of the full version of SQL Server... will it?

-Can you point me to a link with information about how to do the development with the full version of SS, and create the installation package using the SSE?

Thanks for your help.

Advice On Developing A Mobile App That Uses SQL 2005 CE

Mar 9, 2007

Hi,

I am new to SQL 2005 CE but fairly experienced with SQL 2000 and know my way around SQL 2005. I am creating a PDA app that must support the following scenario:

My company has a SQL 2000 server with a "computer assets" database. This asset database must be able to be transferred to an .sdf file (SQL 2005 mobile) on the PDA when the user docks their PDA to the desktop PC (not the same machine as the SQL 2000 server). This transfer can be via an option in the mobile app that is initiated by the user, or automatic.

The mobile application basically supports stock-taking of the assets, so users go out on site and record information about the assets. This information is stored in a separate .sdf database on the PDA.

When the user gets back to the office they dock with their desktop and then must transfer the data from the second .sdf database onto the SQL 200 server. Lets call this the "asset metadata".

thats basically it! but im having issues finding the right process to attack the data transfer tasks.

My issues:

- Firstly, how do i populate the .sdf on the PDA for development purposes? Microsoft tutorials seem to be geared at SQL server 2005 management
studio only. I only have SQL server 2005 Management Studio Express on
my development machine as well as all the necessary SQL 2005 CE SDKs and VS2005. We
do not use SQL Server 2005 at my organisation as yet and it will be some time before we migrate across. In effect im looking for something that behaves like a DTS package to transfer data across.

- How to populate the "asset database" .sdf file from the SQL 2000 server when the user has docked to their desktop PC? (This needs to be refreshed )

- How to transfer the "asset metadata" from the .sdf on the PDA to the SQL server?

ive looked at merge replication a little but am not sure whether this is what i need and again most online information seem to be tailored to SQL Server 2005.

Can anyone kindly point me in the right direction?

An Argument Against Running Or Developing In SQL Compatibility 8.0 Mode

Oct 29, 2007



Hi,

I've been scouring the forums and the web for anything that would substantiate an argument for database application developers to keep developing in SQL 8.0 when we have migrated to SQL 2005.

I read somewhere that compatibility 8.0 mode is an intern stepping stone for migrating from 8 to 9, but it seems 2005 will handle and run compat 8.0 databases just fine.

So am finding it really diffucult to substantiate my argument against running 2005 with all databases in compatibility 8 mode indefinitly.

Any suggestions or links that could help me with this.

Developing DW Project On SQL 2008 - Does It Make Sense?

Dear all,

We started to develop a datawarehouse solution for client back in December 2008 based on SQL 2008.
We are convinced that we can use some of the new feature included in the new version which is the reason we we chossed to go down this path.

Due to the delay of the next version we have some question that I would like to hear you opinion on.

The estimatet "go live" date is during spring (march/april)

Is it wrong to contiue the development on the 2008 version?

We would need to run Release candidate at the customer site until the product is released. Is there any major changes coming up that are already known?

So far in the development we have had no big problems with releasecandidate.

Thank you for you feedback.

SSIS - FTP Task

May 9, 2008

Sorry guys, I'm really new to this. Can somebody tell me the easiest way to use the FTP task with a dynamic local path. I just want the FTP task to send whatever file is in the directory I specify.

I'm creating a package that extracts data from a table to a pipe-delimited file. I then use an external process (since using Expressions for it was a nightmare) to rename the file so that it'll reflect the previous month (e.g. April2008_report.txt). Then, I have to FTP that file. That's where my problem is. It seems I need to specify the exact filename on the local path of the FTP task, and since the filename will change each month... well, you see my problem.

Is there a way to tell the FTP task to just send *.txt, or something to that effect?

Thanks in advance for you help!

Thanks,

Mark

SSIS Task

Jun 21, 2006

Hi ,

I have a master database. Based on certain criteria's I will be creating one new database. Once I have finished the creation, I have to check the value of a particular column in both database tables.

This is actually a status check. if both are not equal i have to update detail database table column value with master column value.

I thought i can use lookup transform for this. The problem is master database table's status datatype and detail table's status datatype is diff.

Can anyone suggest me any other way for this problem?

Need Help!!!! (SP Or SSIS Task)

Sep 6, 2007

I have written the Dynamic TSQL S-Proc. Below is what i wanted to implement in SSIS using foreach loop container as a cursor. But i am little doubtful whether I can achieve the dynamics to this level. I know everything is possible but is it advisable to go for this simple Sproc or SSIS tasks.

I have some 15 tables being populated using this SPROC.

Here is some helpful description
ENTITYNAME gives me the table i need to work
FIELDNAME gives me the field i have to work on
CHANGEDVALUE gives me the value changed in that field
( This three i get from source table which is about 9000 rows and containing 15 possible ENTITY to be work on and 100's of their respective FIELD )

while in Cursors i need to get using these above variables other variables like
FLAG
KeyName

Thrugh SQL1 I get the KeyValue

then using this KeyValue check if the data exist update else insert new data.

QUESTION: IS THIS ADVISABLE to go for SSIS task or just carry with SPROC?

CLOSE Table_cursor
DEALLOCATE Table_cursor
