You can create a variable in your package. Create an Execute SQL task with code similar to:
SELECT ? = TOP 1 my_column FROM myTable
Then in the task's Parameter Mapping tab, select the variable you created and set direction to Output.
Doug BishopDatabase DeveloperCommented:
In the flat file (or whatever format you are exporting to) connection,  you would use that variable as the path for the destination using an Expression to define the path.
For example: ConnectionString = @[User::FolderPath] + "myFile.txt"
