Session.GetObjectsFromSproc(XPClassInfo, 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

Declaration

public ICollection GetObjectsFromSproc(
    XPClassInfo classInfo,
    string sprocName,
    params OperandValue[] parameters
)
Public Function GetObjectsFromSproc(
    classInfo As XPClassInfo,
    sprocName As String,
    ParamArray parameters As OperandValue()
) As ICollection
public ICollection GetObjectsFromSproc(
    XPClassInfo classInfo,
    string sprocName,
    params OperandValue[] parameters
)
Public Function GetObjectsFromSproc(
    classInfo As XPClassInfo,
    sprocName As String,
    ParamArray parameters As OperandValue()
) As ICollection

Parameters

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.

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.

Parameters

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.

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.

Returns

Type Description
ICollection

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

Returns

Type Description
ICollection

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

Remarks

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. The type and the order of classInfo members should exactly match the result set's columns. Note that classInfo should represent a non-persistent class decorated with a NonPersistentAttribute.
Note

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

  • 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.
