Methods

	Name	Description
	AddOutputParameterValueForSync	Adds the output parameter value for synchronization with the enclosed DbParameter, after the query has been executed.
	AddParameter	Adds the parameter to the query's command.
	AddParameterFieldRelation(IEntityFieldCore, DbParameter, TypeConverter)	Adds a new IParameterFieldRelation to the collection of ParameterFieldRelations. An output parameter can be stored once in the collection.
	AddParameterFieldRelation(IEntityFieldCore, DbParameter, TypeConverter, Boolean)	Adds a new IParameterFieldRelation to the collection of ParameterFieldRelations. An output parameter can be stored once in the collection.
	AddParameters	Adds the parameters to the query's command.
	Dispose	Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
	Dispose(Boolean)	Performs the dispose action.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetExceptionInfo	Gets the exception info using the info retriever set to this query object.
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	MergeParameterFieldRelations	Merges the passed in elements in toMerge into this instance. It's up to the caller to remove the elements from the set passed in.
	ReflectOutputValuesInParameterValues	Reflects the output values of output parameters in parameter values, if any.
	ReflectOutputValuesInRelatedFields	Will walk all IParameterFieldRelation instances of this query and reflect the parameter values in the related fields. Only output parameters are taken into account. Used by Insert queries which retrieve Identity / sequence values back from the database after a succesful insert.
	SetCommandText	Sets the command text to the text specified
	SetCommandTimeout	Sets the command timeout.
	ToString	Overloaded ToString implementation (Overrides ObjectToString.)
	ToString(Boolean)	Overloaded ToString implementation
