OLAP Cube при помощи AS3
Задача состои в следующем построить OLAPDATAGRID на основании OLAPCUBE построенного на метаданных некоторых то есть на лету
Для этого не подходит декларативный способ объявления (или наверно я просто не знаю как его прикрутить). Так вот при создании OLAPCUBE у меня не возникают ошибки внешне куб очень похож на то что сосздается при декларативном объявлении но при формировании query возникают непонятные ошибки если ктото обладает Достаточным экспиренсом что бы построить OLAPDG & OLAPCUBE программно прошу помогите пожалуйсто! |
