IDataAccessAdapterFetchProjectionT Method (IDataReader, IRetrievalQuery)

Projects the current resultset of the passed in datareader using the value projectors and the projector specified. The reader will be left open

Namespace: SD.LLBLGen.Pro.ORMSupportClasses
Assembly: SD.LLBLGen.Pro.ORMSupportClasses (in SD.LLBLGen.Pro.ORMSupportClasses.dll) Version: 5.11.0.0 (5.11.23.1114)

Syntax

Copy

List<T> FetchProjection<T>(
	IDataReader reader,
	IRetrievalQuery queryExecuted
)

Function FetchProjection(Of T) ( 
	reader As IDataReader,
	queryExecuted As IRetrievalQuery
) As List(Of T)

Parameters

reader: Type: System.DataIDataReader
The open reader to project the active resultset of
queryExecuted: Type: SD.LLBLGen.Pro.ORMSupportClassesIRetrievalQuery
the query object executed which produced the reader. Pass the executed query object to make sure resultset caching is possible.

Type Parameters

T: Type of the return elements, one for each row

Return Value

Type: ListT
List of instances of T, one for each row in the resultset of reader

Remarks

Use this overload together with FetchDataReader if your datareader contains multiple resultsets, so you have fine-grained control over how you want to project which resultset in the datareader. Resultset caching will occur if the passed in executedQuery is setup to cache its resultset.
