DaoBaseGetAsProjection Method (ListIDataValueProjector, IGeneralDataProjector, ITransaction, IRetrievalQuery, Boolean, Boolean, DictionaryInt32, TypeConverter) |
Executes the passed in retrievalquery and projects the resultset using the value projectors and the projector specified.
IF a transaction is specified, the command is wired to the transaction and executed inside the transaction. The projection results
will be stored in the projector.

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. - transactionToUse
- Type: SD.LLBLGen.Pro.ORMSupportClassesITransaction
The transaction to use, if you execute this method inside a transcation. Specify null otherwise - queryToExecute
- Type: SD.LLBLGen.Pro.ORMSupportClassesIRetrievalQuery
The query to execute. - performValueProjectionsOnRawRow
- Type: SystemBoolean
if set to true the projection method will perform value projections on the plain row prior to using it
in the projector and will create a new object row to store the projected values in. If false, the plain row is passed on as-is - postProcessDBNullValues
- Type: SystemBoolean
if set to true it will perform a DBNull to null conversion on the row passed to the projector. Only specify this to true
if the projector deals with object arrays to the outside. In all other cases make the projectors already convert the DBNull values. - typeConvertersToRun
- Type: System.Collections.GenericDictionaryInt32, TypeConverter
The type converters to use for the query. The key is the index in the result row, the value is the type converter
to run on that value. These type converters have to run prior to the projectors will run.
