Howdy Folks,
I have an ETL project that I want to ask a question about. I want to loop through a folder containing several Access databases, and extract and load each one into a single SQL Server 2005 database. The table layout is the same for all the Access dbs, as well as the SQL db. The number of Access dbs in the folder, their records, and their names will change. Is there a way i can use the SSIS Foreach tool to move through the folder and set the connection string inside the loop?
Thanks for your reply,
Chris
Yes, you can do this.
Use the ForEach File Enumerator to enumerate your list of files. you can use wildcards (e.g. *.mdb)
Store the file path of each file in a variable. You can then use the contents of that variable to dynamically build your connection string using an expression.
Lots of information via Google about this stuff if you want to go hunting or ask here with any pertinent questions.

|||Thanks Jamie (alot ) for your suggestion. I tried using the Foreach File Enumerator with the root path for the Access files and a *.mdb wildcard. Then I created a mapped string variable varFileNameto hold the file path. Inside the loop i have my Data Flow Task. In the data source for the task, I was using the variable in an expression as the ConnectionSting property which didn't work. So I added an OLE DB connection string in the expression like "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + @.[User::varFileName] but i don't think that's the answer.
I've been googling on this but can't find solutions for multiple .mdb's, most of waht i find is dealing with flat files. Great blogs btw.

|||Yep, i went there. Thanks Jamie. My string was ok. Actually what got me running was to set the Foreach Loop Container>Properties>Execution>DelayValidation = True. Works great running the SSIS package on the box with SQL server (as opposed to OLE DB) destinations.
