Creates a new Retrieval query from the elements passed in and executes that retrievalquery to return an open, ready to use IDataReader. The datareader's command behavior is set to the readerBehavior passed in. If a transaction is in progress, the command is wired to the transaction.

Parameters

fields
Type: IEntityFields2
The fields to use to build the query.
filter
Type: IRelationPredicateBucket
The filter.
readerBehavior
Type: System.Data..::..CommandBehavior
The reader behavior to set.
maxNumberOfItemsToReturn
Type: System..::..Int32
The max number of items to return. Specify 0 to return all elements
sortClauses
Type: ISortExpression
The sort clauses.
allowDuplicates
Type: System..::..Boolean
If set to true, allow duplicates in the resultset, otherwise try to emit DISTINCT (if possible).

Return Value

Type: IDataReader
Open, ready to use IDataReader

Remarks

Advanced functionality: be aware that the datareader returned is open, and the dataaccessadapter's connection is also open
