public abstract class DaoBase : IDao

The DaoBase type exposes the following members.

Constructors
Properties
  NameDescription
Public propertyStatic memberCommandTimeOut
Gets / sets the command time out (in seconds). This is a global setting, so every Command object created after you've set this property to a value will have that value as CommandTimeOut. Default is 30 seconds which is the ADO.NET default.
Public propertyEntityFactoryToUse
Gets / sets entityFactory to use
Public propertyFunctionMappings
Gets the function mappings for the DQE related to this Dao class. These function mappings are static and therefore not changeable.

Fields
  NameDescription
Public fieldStatic memberParameterisedPrefetchPathThreshold
The parameterised prefetch path threshold. This threshold is used to determine when the prefetch path logic should switch to a subquery or when it should use a WHERE field IN (value1, value2, ... valueN) construct, based on the # of elements in the parent collection. If that # of elements exceeds this threshold, a subquery is constructed, otherwise field IN (value1, value2, ...) construct is used. The default value is 50. On average, this is faster than using a subquery which returns 50 elements. Use this to tune prefetch path fetch logic for your particular needs.

This threshold is also used to determine if paging is possible. A page size bigger than this threshold will disable the paging functionality when using paging + prefetch paths.
