Hierarchical Relation Conditions

Hierarchical relation conditions specify the comparison of the relationship of a hierarchy member to itself or to another member of the hierarchy.

Syntax

expr1 IS [ NOT ] 
 { PARENT 
 | CHILD 
 | ANCESTOR
 | ROOT_ANCESTOR
 | DESCENDANT
 | LEAF_DESCENDANT
 | RELATIVE
 }
 [ OR SELF ] OF expr2 WITHIN hierarchy

Arguments

expr1 is any expression, including a literal or a column, that resolves to a dimension member.

PARENT compares expr1 as the parent of expr2.

CHILD compares expr1 as a child of expr2.

ANCESTOR compares expr1 as an ancestor of expr2.

ROOT_ANCESTOR compares expr1 as the highest-level ancestor of expr2.

DESCENDANT compares expr1 as a descendant of expr2.

LEAF_DESCENDANT compares expr1 as a descendant that has no children of expr2.

RELATIVE compares expr1 as a dimension member that has a parent in common with expr2.

OR SELF compares expr1 as the same dimension member as expr2.

expr2 is any expression, including a literal or a column, that resolves to a dimension member.

hierarchy is the hierarchy to consider when determining the relationship between expr1 and expr2, expressed in the form dimension_name.hierarchy_name, as in PRODUCT.PRIMARY, or owner.dimension_name.hierarchy_name, as in GLOBAL.PRODUCT.PRIMARY.

Examples

TIME.DIM_KEY IS CHILD OR SELF OF 'FY2008' WITHIN TIME.FISCAL
'FY2008' IS ROOT_ANCESTOR OR SELF OF TIME.DIM_KEY WITHIN TIME.FISCAL
'MEMORY' IS NOT ANCESTOR OF PRODUCT.DIM_KEY WITHIN GLOBAL.PRODUCT.PRIMARY
