Used .NET Framework Data Provider for OLE DB instead of .NET Framework Data Provider for Oracle since it's not available in the 2012. When creating a sql datasource, "[" and "]" are used in the sql statments and it's erroring out because of brackets. Didn't have this problem in the 2010 version. I'm using the VWD 2012 with Oracle ODT with ODAC1120320_32bit and .Net Framework 4.5.
Your help will be greatly appreciated.
