I want to construct a dataset based on all rows passed in from a source and, upon running through all of them, push each dataset record to an output.
Unfortunately, upon calling the AddRow method, I get an "object reference not set to an instance of an object" error. Am I not allowed to create new rows in PostExecute?
I have a task configured on the post execute event handler of a package expecting this task to be executed only once after the completion of all the other tasks in the package. But I found the task configured on the post execute event of the package getting executed as many times as the number of tasks in the package + 1 . Is there any workaround for this problem?
View 1 Replies View RelatedHi,
I have an SSIS package that populates a field with "DEFAULT" at the start of execution and i have an Execute SQL task in PostExecute EventHandler that executes a stored proc to update the said field to "SUCCESS".
I already created a blank script task to connect to the Execute SQL task and placed in the precedence constraint editor: @[System :: PackageName] == @[System :: SourceName] so that it would execute only when the package completes execution.
My problem is that there are times (probably about 1 out of 50) that the "DEFAULT" value does not get updated. I dont know why this is happening because I expect that this should always be updated since the stored proc is in PostExecute (i suppose successful or even failed execution always does what is in the PostExecute event handler). I don't know why this is happening and it is so hard to replicate.
What do you think?
Thanks!
Hi,
I have a Script Component that needs to read values from a User Variable in PreExecute, modify the values and write them back to the Variable in PostExecute.
The Problem is it works just fine in DEV environment where only the SSIS tools are installed but not the service. But it failes with error in Test enviroment.
Error No: -1073450910.

Any idea what the problem is?
Is there any other way i can accomplish this?
Thanks.
hi,
I am developing a ASP.NET application using SQL Server as my database.
I want to create a number that is unique.
The number will have 8 digits.
first 2 digits correspond to year. ex:04 or 03
the next 6 digits start with 000001 and it should get added for each new entry of data.
i am not able to generate number in the way i said. I am relatively new to SQL. so any suggestions as how to go about solving the problem???. Are there any samples/codes available for this.
Any help would be highly appreciated.
thanks,

Hi all,
I have generated an SQL script such that when it is run, it will automatically create tables if not existing or drop the existing tables. The problem I have is that, is there any way I can also make the script create not only the tables but also transfer the data from the old database to the new database?
I would really appreciate if any of you could point me to any existing programs, scripts etc that can do that. Thanks in advance

Celia
Is there a way to generate SQL Scripts from a stored procedure?
For disaster recovery and documenation reasons, we'd like to create scripts of our databases periodically. I, being somewhat lazy, would like to automate this so I really don't have to remember to run this every so often.
Any help would be appreciated.
Is there a way to generate SQL scripts from other than SQL Enterprise Manager?

(SELECT
CASE
WHEN SUBSTRING(ISNULL(max(seed),'00000'),1,6) = convert(varchar(10), getdate(), 12)
THEN SUBSTRING(ISNULL(max(seed),'00000'),7,12)
ELSE '000000'

View 7 Replies View RelatedHi,
we would like to generate SSIS packages(connections, data flow tasks, etc..) programatically using C#. Is it possible to do so?
At present we are creating packages by dragging and dropping required componets from toolbox and configuring them manually. We have a requirement of creating around 300 packages every week. Manual creation of packages is really a nightmare.
I heard from one of friends that using c# we can create packages. is it true? if so, can we view/edit the packages generated using c# using VS 2005 IDE(if required) ?

Hello,
SRS 2005 provides functionality for loading and rendering reports on fly using LoadReportDefinition and Render methods defined in ReportExecutionService webservice.
I was wondering if the same/similar behaviour can be accomplished in Reporting Services 2000.

What does N indicate in the following script
SELECT * FROM dbo.sysobjects WHERE id = OBJECT_ID(N'[dbo].xxxx' )
Plz can anyone explain
EXEC dbo.sp_executesql @statement = N'Create View xxxxx'
I've been given an excel file that lists:
userID's,
Names

I need to convert this list into sql server logins. Can this be done via a tsql statement? if so how, and if it cant be done via a statement then what other way can it be done.
Many thanks in advance.
I'm having problems generating the primary key for a sql server table. I use a slowly changing dimension to discriminate modified and new records. The primary key in the SQL Server table is a combo number/letter incremental (ex. 0000A, 0001A...9999A, 0000B...). I tried creating Instead of insert and For insert trigger for a table but this doesn't seem to do the work.
What are my other options? How can I generate a primary key for every new row?
Any advice is appreciated.

Hello all,
I have a few questions relating to scripts and I'm looking for some help, or at least a point in the right direction.
1) I'm generating CREATE scripts to move a number of tables/procedures/functions from my testing database to my production database. The issue I have is the script doesn't seem to be generated in a particular order, so I'm getting errors when a table/procedure/function is created that references something that hasn't been created yet. Is there a setting available to create the script in a specific order to prevent these errors?
2) This is somewhat related to the first question. I need to drop all the tables/procedures/functions before I re-create them. Can I set all the DROPs at the beginning of the script, and then run all the CREATEs?
3) Eventually the database will be ready for production and in use. And eventually I'll be asked to make changes, without erasing existing data. Can I accomplish this using the generate scripts feature? What topics should I be investigating when looking into conducting these types of updates? "Updating database" is too general and I'm not sure the technical term. I've done very simple DB-related tasks so I'm trying to figure out what I'm looking for so I can educate myself. Basically, I don't know what I don't know.
Any help is appreciated. Thanks.

View 2 Replies View RelatedHi all,
I have a question about generating membership numbers on the fly when someone registers to my website.
Rather than using the auto increment field as a membership number, I would rather keep it as just as the ID for the record and I would like to have a seperate membership number that looks something similar to this...
SR357324J
This will then stay with them for the lifetime of their membership and be on their printed loyalty card.
My questions are...
1) Is there a 'good practice' for membership number format and generation?
2) If this was used as a unique field, is there a degradation in performance when looking up records due to it being alphanumeric.
I may be well off base here, however these are my thoughts so far and your opinion/help is greatly appreciated.
Thanks for your contribution.
Hi, I'm looking for a way to take an XML feed and basically do what this article describes: http://msdn.microsoft.com/msdnmag/issues/03/05/MetaDataServices/
(In short, take in XML, generate a database generation script, creating that database, then load the XML data into said database.)
But, the above article involves user interaction and I would like this all automated, ie: in .NET 2.0/C#
Does anyone know how to do this?
Cheers,
Matt.

Hi,
I have a table with a primary key, what I really need is something like an IDENTITY, but with the character 'X' and the last to digits of the year added on the front. Is there another way to update the field automatically like an IDENTITY would do, automatically incrementing as fields are inserted.
Hello
I'm looking for a way of generating the next key value that works in MS and Sybase SQL Servers. Sybase identity columns are a bit dodgy, so...
If I have a separate table NextKey (NextKey int) with one row that I update as follows...
declare @NextKey int
update NextKey set NextKey = NextKey + 1, @NextKey = NextKey + 1
insert into myTable (PrimaryKeyCol, ....) values (@NextKey, ....)
are there any problems with concurrency ? As I see it the update will lock the row so different connections will always come up with a different @NextKey value....
Thanks

Hello,
I need to know how to generating a sequence number, for example, from 300,000 to 900,000 without skipping any number due to failure. For example, if user 1 request a number then he/she will get 300000 in a transaction. User 2 will get 300001. How ever user 1's transaction fails, then the next request should get 300000. Is it possible to do this in SQL2K? If so, how do I create a table that and stored procedure that can do this.
Thank you so much.
