QueryTranslatorFactory, assembly query. Defaults to the built-in DefaultQueryProvider. LinqProvider, assembly query. Defaults to null no rewriter. QueryModelRewriterFactory, assembly query. Defaults to null no registrar.
ExpressionTransformerRegistrar, assembly linqtohql. LinqToHqlGeneratorsRegistry, assembly linqtohql. Defaults to Dialect. With create-drop , the database schema will be dropped when the ISessionFactory is closed explicitly. Disabled by default. Enabled by default.
Defaults to the built-in StaticProxyFactoryFactory. ProxyFactoryFactory, assembly collectiontype. Defaults to the built-in DefaultCollectionTypeFactory. CollectionTypeFactory, assembly transaction. TransactionFactory, assembly transaction. Defaults to 1. CurrentSessionContext, assembly id. The default is to interpret it as the high boundary. Statistics property. When true , each session will have an unique Guid that can be retrieved with ISessionImplementor. SessionId , otherwise ISessionImplementor.
SessionId will be Guid. DateTime2 is used instead of DbType. This is intended to work around issues like: System. Fractional second precision exceeds the scale specified in the parameter binding.
NHibernate will attempt to detect this setting automatically from the connection string, but if the connection or connection string is being handled by the application instead of by NHibernate, you can use the sqlite. The value can be true or false. It allows using another logger than log4net.

Enable ordering of update statements for the purpose of more efficient batching. If batching is enabled, specify that versioned data can also be batched. The class name of a IBatcherFactory implementation. Some database vendor data reader implementation have inefficient columnName-to-columnIndex resolution.
The class name of a NHibernate Dialect - enables certain platform dependent features. Qualify unqualified table names with the given catalog name in generated SQL.
Set a maximum "depth" for the outer join fetch tree for single-ended associations one-to-one, many-to-one. Enable the second level cache. The class name of a ICacheProvider implementation. Optimize second-level cache operation to minimize writes, at the cost of more frequent reads useful for clustered caches. Enable the query cache, individual queries still have to be set cacheable. The class name of a custom IQueryCacheFactory implementation. A prefix to use for second-level cache region names.
The default expiration delay in seconds for cached entries, for providers supporting this setting. Mapping from tokens in NHibernate queries to SQL tokens tokens might be function or literal names, for example. Set the default length used in casting when the target type is length bound and does not specify it. Set the default precision used in casting when the target type is decimal and does not specify it. Set the default scale used in casting when the target type is decimal and does not specify it.
