C# Class Habanero.Base.CriteriaDB

This class inherits from the Criteria class and implements a ToString(Habanero.Base.ISqlFormatter,Habanero.Base.CriteriaDB.AddParameterDelegate,System.Collections.Generic.IDictionary{string,string}) behaviour. This allows the formatting of a criteria object into a format specific for the database.

Public Methods

Method	Description
CriteriaDB ( Criteria criteria ) : System	Constructor for a Database critieria. takes the Criteria object that it wraps as a parameter.
ToString ( ) : string	Returns a that represents the current .
ToString ( ISqlFormatter formatter, AddParameterDelegate addParameter ) : string	Converts this Criteria to a string for use in a sql statement.
ToString ( ISqlFormatter formatter, AddParameterDelegate addParameter, string>.IDictionary aliases ) : string	Converts this Criteria object to a string, using field names instead of property names and entity names (aliased) instead of source names. The AddParameterDelegate allows a database query builder to create a parameter value when adding the value to the string for use with parametrized SQL. Also see ISqlStatement. The ToString() method uses this method with a simple delegate that converts DateTimes and Guids to sensible string representations and to Provide a set of aliases to replace entity names with their aliases.
