Name Type Description
classInfo XPClassInfo

An XPClassInfo object which contains the metadata information of the persistent objects that are retrieved based on the stored procedure's results.

alwaysGetFromDataStore Boolean

true to reload persistent objects from storage, if they are found in memory; otherwise, false.

sprocName String

A String value that specifies the stored procedure's name.

parameters OperandValue[]

An array of OperandValue objects representing parameters to pass to the stored procedure.


Type Description

A collection of persistent objects with specified key property values.


First, the GetObjectsByKeyFromSproc method executes the specified stored procedure with parameters and retrieves key property values into a result set. Then, the method searches in memory for persistent objects with retrieved key property values. If such objects are found, they are not reloaded. To get the up-to-date objects from storage, the alwaysGetFromDb parameter must be set to true.


The GetObjectsByKeyFromSproc method does not find objects until they are saved to a data store.
