SQL and Outlook: Enable Database Access and Updates Through Exchange and Any E-mail Client

Using Microsoft technologies, you can insert, edit, query, and delete database entries using any e-mail client such as Hotmail, Outlook, Yahoo, or even WAP phone. While e-mail is certainly a powerful and widely used tool, it is usually not integrated with an application for performing any tasks other than sending reminders. The application scenario described here, an e-mail-based SQL update program, uses a simple data model; however, this solution will apply to any data model that you are working with. It will also eliminate the need for complex n-tier Internet applications and serves as a low maintenance solution for providing data access.

Errors in the back-end database access module. OLE DB reported an overflow of the data type for colu

Getting an error when processing a dimension, Errors in the back-end database access module. OLE DB reported an overflow of the data type for column 0. Errors in the OLAP storage engine: An error occurred while the 'xxxxxx' attribute of the 'Dim XXXXXX' dimension from the 'XXXXXXX' database was being processed. Content of this dimension is very similar to one that is processing no problem. The content of the dimension is one field only of type date. The original content was imported through SSIS from a DB2 database on an iseries machine. Thought a first the issue was because of the data contains some null values but the dimension the process OK also has some null values. The dimension that processes ok is also a single field of type date. Any help greatly appreciated, Roscoe

Restoring 2008 Database with Filestream - Process cannot access file error

I'm trying to restore a copy of a database that has a filestream and am getting the error below. I've tried with move option to specify a new path and left it with default path, neither worked. Did a trace with procmon, didn't see anything. FileStream1 is a new folder that the restore process creates. I've deleted the folder, tried it with a new name, re-took the backup from the source machine, restarted SQL, rebooted the machine, drive permissions are open. I've run out of ideas on how to debug further. Looking up the error online wasn't much help either. Msg 3634, Level 16, State 1, Line 1 The operating system returned the error '32(The process cannot access the file because it is being used by another process.)' while attempting 'OpenFile' on 'X:\Data\FileStream1\4ecb2e48-0eee-4c99-a3f0-f1e6c7f00b24\f2efe374-9481-4c1b-a7f2-dcdcee350807\0000001b-0000aaa6-00f6'.
