In my application i used database first concept, i created one edmx file using sqlserver database tables, after that i want to use same edmx for oracle database tables,how can i do that.
Note:Sql server database tables and oracle database tables these two are same structure .
but in sql server if we use nvarchar for that in oracle we use varchar2 .
Please tell me what are the changes required to use same edmx file for oracle also.
