IDataAccessAdapterFetchProjection Method (ListIDataValueProjector, IGeneralDataProjector, 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: 5.4.0.0 (5.4.0)
Syntax void FetchProjection(
List<IDataValueProjector> valueProjectors,
IGeneralDataProjector projector,
IDataReader reader,
IRetrievalQuery executedQuery
)
Sub FetchProjection (
valueProjectors As List(Of IDataValueProjector),
projector As IGeneralDataProjector,
reader As IDataReader,
executedQuery As IRetrievalQuery
)
Parameters
- valueProjectors
- Type: System.Collections.GenericListIDataValueProjector
The value projectors. - projector
- Type: SD.LLBLGen.Pro.ORMSupportClassesIGeneralDataProjector
The projector to use for projecting a plain row onto a new object provided by the projector. - reader
- Type: System.DataIDataReader
The reader which points to the first row of a resultset - executedQuery
- 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.
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.
