Gidrel Relation

A gidrel relation is a relation between a NUMBER dimension, the hierarchical dimension, and the hierlist dimension that contains the grouping ID of each dimension member in each hierarchy of the hierarchical dimension. It also has a $GID_DEPTH property that identifies the depth within a hierarchy of each dimension member.

Example: Defining and Populating a gidrel Relation named geog_gidrel illustrates defining and populating this type of relation.

Example 1-10 Defining and Populating a gidrel Relation named geog_gidrel

"Create a dimension that has values that are numbers
DEFINE gid_dimension DIMENSION NUMBER (38,0)"Add values to that dimension 
"This example uses MAINTAIN ADD to add a few numbers
MAINTAIN gid_dimension ADD 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 
 
"Define the gidrel relation
DEFINE geog_gidrel RELATION gid_dimension <geog geog_hierlist>
"Display the complete definition of the geog_gidrel relation
"Note that it has no properties
DEFINE GEOG_GIDREL RELATION GID_DIMENSION <GEOG GEOG_HIERLIST>
"Populate the gidrel relation using the GROUPINGID command 
GROUPINGID geog_parentrel INTO geog_gidrel USING geog_levelrel INHIERARCHY geog_inhier
"Display the values of the geog_gidrel relation
 
REPORT down geog w 20 geog_gidrel
