Returns an associated list of query filter properties for the specified feature layer.
This is a new option that consolidates older versions of esri_featurelayer_getquery and esri_docfeaturelayer_getquery in one function. It returns the QUERYFILTER of an existing web or document feature layer as an associated list representing a query related to the feature layer.
Syntax
(esri_featurelayer_getquery flname [subtype])
Arguments
- flname | string | required | An existing feature layer name in the drawing.
- subtype | string | optional | An existing feature layer subtype name in the drawing.
Example usage 1
Attempt to get the filter query properties for the Shelters feature layer as an associated list:(esri_featurelayer_getquery "Shelters")
Result example usage 1
Returns the filter query properties for the Shelters feature layer as an associated list which consists of the DXF™ code for layer 8 and a comma separated string of AutoCAD layer names for the parent features and subtypes:
((8 . "ESRI_Shelters,ESRI_Shelters_4,ESRI_Shelters_2,ESRI_Shelters_3,ESRI_Shelters_1,ESRI_Shelters_5,ESRI_Shelters_6"))Example usage 2
Attempt to get the filter query properties for the Shelters_2 subtype of the Shelters feature layer as an associated list(esri_featurelayer_getquery "Shelters" "Shelters_2")
Result example usage 2
Returns the filter query properties for the Shelters_2 subtype of the Shelters feature layer as an associated list which consists of the DXF™ code for layer 8 and the AutoCAD layer name ESRI_Shelters_2:
((8 . "ESRI_Shelters_2"))Return values
- If successful, returns an associated list representing the query used to define the feature layer. The associated list contains DXF™ codes as key values and an associated value that combine to create a filtering query for the feature layer.
- If failed, returns a list with the first value of nil and then an associated list containing the key value "Error" and an associated error message as a string: (nil ("Error" . "<message>"))
Failed return values
A failed return value can occur for any of the following reasons:
- (nil ("Error" . "Feature layer not
found."))
The specified feature layer value is not a valid feature layer in the drawing.
