Informations supplémentaires

The expression is not correct. Each time the expression evaluates, a new GUID is returned, leading to an infinite loop. Define a GUID initially and check if the field value contains a GUID. If it is empty, create and assign a GUID using the Guid() function. If not empty, return the current GUID field value. For example, to calculate a random GUID in a field, use the following expression and replace FIELDNAME with the name of the field: var id = $feature.FIELDNAME IIf(id==null, guid(), id)

var id = $feature.FIELDNAME

IIf(id==null, guid(), id)
