[Nhibernate-commit] nhibernate/src/NHibernate/Driver DriverBase.cs,1.1,1.2 IDriver.cs,1.1,1.2

[Michael D. <mik...@us...>]

Update of /cvsroot/nhibernate/nhibernate/src/NHibernate/Driver
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv22643/NHibernate/Driver

Modified Files:
	DriverBase.cs IDriver.cs 
Log Message:
Added a property to indicate if the Data Provider supports Multiple Open 
IDataReaders.  If you're Driver supports having more than 1 open 
IDataReader at the same time against the same IDbConnection then override
this with true.  
MsSql2000 is a DataProvider that only supports 1 open IDataReader.  I don't
know about the other Data Providers so they have not overridden the base
class which default to false.
