A common requirement when building a data warehouse is to be able to get all rows from a staging table where the business key is not in the dimension table. For example, I may want to get all rows from my STG_DATE table where the DateID is not in DIM_DATE.DateID.

One of the new tasks in SQL Server 2005 is the For Loop Container. In this article we will demonstrate a few simple examples of how this works. Firstly it is worth mentioning that the For Loop Container follows the same logic as most other loop mechanism you may have come across, in that it will continue to iterate whilst the loop test (EvalExpression) is true. There is a known issue with the EvalExpression description in the task UI being wrong at present. (SQL Server 2005 Beta 2).

SQL Server 2005 has made it a lot easier for us to loop over a collection and with each iteration do something with the item retrieved. In this article we are going to show you how to iterate over a folder looking at the files within and doing something with those files. In this instance we will be entering the filename into a SQL Server table and we will then load the actual files we have just found into another SQL Server table. You will note here that there is still the need to load the file names into a table as an intermediate step just as we need to do in SQL Server 2000.

In this article we are going to assume a few things about the reader as we want to concentrate as much as possible on the Script Component itself and not the peripheral stuff
The things we will assume are:
* You are happy with adding a DataFlow task to the designer in Workflow
* You are happy to configure an OLEDB Source adapter
* You are comfortable with configuring mappings in the Destination adapter

To do some of the stuff we wanted in SQL Server 2000 DTS we had put together some serious glue code and to be honest it wasn't pretty. One of the things that we used to have to do this way was if we wanted to implement using workflow constraints a Logical OR. Well that has changed and it is now really simple and this article is going to show you how to implement it.

In the newsgroups we have been asked on a number of occasions how to execute a stored procedure once for every row of input data. There's currently no really good way of doing this but in SQL Server 2005 DTS that is about to change. This article is going to show you how to take values from a source table and for every row execute a stored procedure which inserts values into another table.

SQL Server Express, a free product based on SQL Server 2005 technology, includes the unique Application XCopy feature, and networking and security that differ from other SQL Server 2005 editions. These topics and the integration of SQL Server Express with Visual Studio 2005 are discussed. Compare this product with the existing Microsoft free databases like MSDE and Jet.
