问题 I am working with MS Excel files in my web application built in Azure environment. I never run into following error when I am trying to access the excel file on my development fabric.

问题 I have an Oracle 11g XE database that I would like to transfer into SQL Server Express 2005. At first I thought I'd just generate the tables in Oracle as SQL, manipulate the data formats, and run the query in SQL Server.
