Session.GetObjectsFromSproc(XPClassInfo, List<XPMemberInfo>, String, OperandValue[]) Method

Executes a stored procedure and returns its result set as a collection of non-persistent objects.

Namespace: DevExpress.Xpo

Assembly: DevExpress.Xpo.v19.2.dll


public ICollection GetObjectsFromSproc(
    XPClassInfo classInfo,
    List<XPMemberInfo> members,
    string sprocName,
    params OperandValue[] parameters
Public Function GetObjectsFromSproc(
    classInfo As XPClassInfo,
    members As List(Of XPMemberInfo),
    sprocName As String,
    ParamArray parameters As OperandValue()
) As ICollection


Name Type Description
classInfo XPClassInfo

An XPClassInfo object which contains the metadata information on a non-persistent class corresponding to the stored procedure's result set. The class must be decorated with NonPersistentAttribute.

members List<XPMemberInfo>

A list of XPMemberInfo objects representing classInfo members that are mapped to the stored procedure's result set columns. The order of list elements should correspond to the order of result set columns.

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 non-persistent classInfo objects instantiated with data obtained via the specified stored procedure.


This method performs the following:

  • Executes the specified stored procedure with parameters and obtains the result as a result set.
  • Populates a collection with classInfo objects that are instantiated with the result set's data based on the mapping information passed as the members parameter. Note that classInfo should represent a non-persistent class decorated with a NonPersistentAttribute.

The GetObjectsFromSproc method throws an exception if the members list includes any of the following classInfo members:

  • A property that is not defined within the classInfo object.
  • A struct type member.
  • A reference to a class with a struct type member.
  • A collection used in object relations.
