PARTITION (partition_template_name)
Example 8-60 Retrieving the Names of Partitions
Assume that you have defined the following objects.
DEFINE time DIMENSION TEXT
DEFINE product DIMENSION TEXT
DEFINE time_parentrel RELATION time <time>
DEFINE partition_sales_by_year PARTITION TEMPLATE <time product> -
PARTITION BY LIST (time)(PARTITION time_2003 VALUES -
('2003','Dec2003', 'Jan2003','31Dec2003','01Dec2003','31Jan2003','01Jan2003')-
<time product> PARTITION time_2002 VALUES -
('2002', 'Dec2002', 'Jan2002', '31Dec2002', '01Dec2002','31Jan2002','01Jan2002')-

DEFINE sales DECIMAL <partition_sales_by_year<time product>>
Assume that these object have the values shown in the following report.

As shown in the following code, you can use the PARTITION function to retrieve the names of the partition in which a a value is stored.
SHOW partition_sales_by_year
<2003, 00001>
LIMIT time to '31Jan2002'
SHOW PARTITION(partition_sales_by_year)
TIME_2002
LIMIT time to ALL
REPORT DOWN time PARTITION(partition_sales_by_year)
