Объявление в базе данных BLOB фильтра. Доступно в: DSQL, ESQL. Синтаксис: DECLARE FILTER filtername INPUT_TYPE OUTPUT_TYPE ENTRY_POINT 'function_name' MODULE_NAME 'library_name'; фильтра с уже существующими комбинациями входных и выходных типов BLOB приведёт к ошибке. Предложение INPUT_TYPE идентифицирует тип преобразуемого объекта (подтип BLOB). Предложение OUTPUT_TYPE идентифицирует
