    • An aggregated query is used to fetch data from a multidimensional database, such as an OLAP cube. The aggregated query combines individual queries that are used to fetch data from the multidimensional database into a single query. A determination is made as to what dimensions and hierarchies of the multidimensional database are used by the queries that are contained as cube functions within formulas in cells of a spreadsheet. Based on the dimensions and hierarchies that are used within the multidimensional database, a tuple for each of the individual queries is created that has the same dimensionality. These tuples having the same dimensionality are then combined to create the aggregated query.
    • 聚合查询用于从多维数据库(如OLAP多维数据集)中提取数据。 聚合查询将用于从多维数据库中获取数据的单个查询组合成单个查询。 确定在电子表格的单元格中的公式中作为多维数据集函数包含的查询使用多维数据库的维度和层次结构。 基于在多维数据库中使用的维度和层次结构,创建具有相同维度的每个单独查询的元组。 然后组合具有相同维度的这些元组以创建聚合查询。
