i need to create switchable web.config file which can configure N Hibernate to work with either MS-SQL Server or Oracle

I'm having 2 configuration files and one web.config files

sqlcongif.config oracleconfig.config

if i want only SQL config i need to point to sqlconfigure.config in web.config or else only oracle i need to point oracleconfig.config

tried with child config and other web options .

i found that similar problem when we are having connection strings in web config files is there any options we can do this ?

thanks in advance :)
