The AW hierarchy element corresponds to the Oracle OLAP hierarchy object in the Physical layer. The AW hierarchy tag includes the following attributes: 14-32 Oracle Fusion Middleware Integrators Guide for Oracle Business Intelligence Enterprise Edition The AW hierarchy tag includes the following child elements: Syntax AWHierarchy … type= isDefault= extName= dataType= nullable= precision= scale= Levels RefAWLevel .. Levels Columns RefAWColumn … Columns MemberKey RefAWColumn … MemberKey AWHierarchy Table 14–33 AW Hierarchy Tag Attributes Attribute Name Description type The type of Oracle OLAP hierarchy value or level. isDefault If set to true, indicates that this is the default hierarchy for the Oracle OLAP dimension. extName The physical name that is used when referencing the hierarchy in physical SQL queries. dataType The data type of the Oracle OLAP hierarchy, such as VARCHAR. nullable If set to true, indicates that null values are allowed for the Oracle OLAP hierarchy. This allows null values to be returned to the user, which is expected with certain functions and with outer joins. precision The precision of the data type of the Oracle OLAP hierarchy. scale The scale of the data type of the Oracle OLAP hierarchy. Table 14–34 AW Hierarchy Child Elements Attribute Name Description Levels For level-based hierarchies only. References the level or levels for this Oracle OLAP hierarchy. Each level is contained in a sub-element called RefAWLevel. Columns For value-based hierarchies only. References the column or columns for this Oracle OLAP hierarchy. Each column is contained in a sub-element called RefAWColumn. MemberKey References the member key for parent-child hierarchies. The member key is contained in a sub-element called RefAWColumn.
