Gets the full field spec of the ID field for a layer.
a = GetIDField(string layer_name)
|
Argument |
Contents |
|
layer_name |
The name of the layer |
The full field spec of the ID field for the layer.
If the layer is CDF and has a numeric DATA field, GetIDField() returns that field instead of the KEY field.
If layer_name is the view name of a mappable join, the field returned will belong to the join, not the layer (base view).
If layer_name is null, returns the ID field for the current layer (base view), not the current view, if it is a mappable join of the layer and hence different from the base view.
