CALC_CROP_TO_NULL


Applies to: CELONIS 4.2 CELONIS 4.3 CELONIS 4.4

This operator crops cases to a range of activities. All values outside this range are mapped to null. Values within the range are kept, in contrast to CALC_CROP which maps them to 1.
Этот оператор обрабатывает случаи для ряда видов деятельности. Все значения за пределами этого диапазона отображаются на ноль. Значения в пределах диапазона сохраняются, в отличие от CALC_CROP, который отображает их на 1.

Syntax


CALC_CROP_TO_NULL(<begin_range_specifier> TO <end_range_specifier>, <column>)
begin_range_specifier = CASE_START | FIRST_OCCURRENCE [ <activity_name> ] | LAST_OCCURRENCE [<activity_name>]
end_range_specifier = CASE_END | FIRST_OCCURRENCE [ <activity_name> ] | LAST_OCCURRENCE [<activity_name>]

column : Any string column which can be joined to the activity table
Любой строковый столбец, который можно присоединить к таблице активности

Range Specifier

FIRST_OCCURRENCE['activity'] : First occurrence of the specified activity type.
Первое вхождение указанного вида деятельности.
LAST_OCCURRENCE['activity'] : Last occurrence of the specified activity type.
Последнее вхождение указанного вида деятельности.
CASE_START : Range begins at the start of the case.
Диапазон начинается в начале дела.
CASE_END : Range ends at the end of the case
Диапазон заканчивается в конце дела

Examples


Simple example with one matching (In case 1 B comes before C) and one not matching (In case 2 there is no C after B) case.
Простой пример с одним подходящим (в случае 1 B предшествует C) и одним не соответствующим (в случае 2 нет C после B) case.

If range specifiers are conflicting, e.g. end activity is before start activity the complete case is mapped to null.
Если спецификаторы диапазона конфликтуют, например, конечное действие перед началом действия, полный случай отображается на ноль.
