ArcGIS.Core.Data Namespace / Table Class / Select(QueryFilter,SelectionType,SelectionOption) Method
A filter used when querying the table.
Specifies whether the selection should be based on SelectionType.ObjectID or SelectionType.GlobalID.
Specifies the content of the Selection.
Example

In This Topic
    Select(QueryFilter,SelectionType,SelectionOption) Method
    In This Topic
    Creates a selection of specific rows in this Table that satisfy the criteria set in the queryFilter. This method must be called on the MCT. Use QueuedTask.Run.
    Syntax

    Parameters

    queryFilter
    A filter used when querying the table.
    selectionType
    Specifies whether the selection should be based on SelectionType.ObjectID or SelectionType.GlobalID.
    selectionOption
    Specifies the content of the Selection.

    Return Value

    A new Selection instance that satisfies the criteria set in queryFilter and selectionOption.
    Exceptions
    ExceptionDescription
    If queryFilter is an instance of SpatialQueryFilter, either both the 'FilterGeometry' and 'SpatialRelationship' properties are set or both are not set. Otherwise, an ArgumentException will be raised.
    selectionType or selectionOption is invalid.

    selectionType is specified as SelectionType.GlobalID and the underlying data store of this table or feature class is not an enterprise geodatabase.

    -or-

    The underlying data store (e.g., a Database) does not support this operation.

    The table or feature class is not global ID enabled.
    A geodatabase-related exception has occurred.
    Remarks
    In order to specify selectionType as SelectionType.GlobalID, two preconditions must be satisfied:
    1. The underlying data store of this table or feature class must be an enterprise geodatabase.
    2. The table or feature class must have global IDs.
