03 How to configure List partition in Oracle
Use list partitioning when you require explicit control over how rows map to partitions. You can specify a list of discrete
values for the partitioning column in the description for each partition. This is different from range partitioning, where a
range of values is associated with a partition, and from hash partitioning, where the user has no control of the row to
partition mapping.
List partitioning allows unordered and unrelated sets of data to be grouped and organized together very naturally
The following example creates a table with list partitioning
create table customers (custcode number(5),
Name varchar2(20),
Addr varchar2(10,2),
City varchar2(20),
Bal number(10,2))
Partition by list (city),
Partition north_India values (‘DELHI’,’CHANDIGARH’),
Partition east_India values (‘KOLKOTA’,’PATNA’),
Partition south_India values (‘HYDERABAD’,’BANGALORE’,’CHENNAI’),
Partition west India values (‘BOMBAY’,’GOA’);
If a row is inserted in the above table then oracle maps the value of city column and whichever partition list matches the
city column the row is stored in that partition.
