Hi,
If i'm correct you want to store the sessions in Sql server without creating any tables.
Here is a sample configuration block that you can add in web.config
<sessionstate>
mode="SQLServer"
allowCustomSqlDatabase="true"
sqlConnectionString="Data Source=.;Initial Catalog=SessionStateDB;"
cookieless="false"
timeout="20"
</sessionstate>
Also for furhter information plz refer this articel
