Behavior of Table Partitions
A table partition name is associated with a partitioning criterion. Data that satisfies the criterion is stored in the storage group associated with the table partition name.
The following rules govern table partitions:
- Supported partitioning types include range partitioning and list partitioning.
- SQL DDL commands
CREATE TABLE and
ALTER TABLE will provide the ability to manage table partitions and associate them with storage groups.
- A table partition is local to the table, that is, it has rows from one table only.
- A table partition is associated with exactly one storage group.
- A version of a row in a partitioned table is mapped to exactly one table partition.
- A table can only have one partition policy defined.
- In addition to associating a table with multiple storage groups, a table can be created and assigned to just one storage group.
- The limit on the number of partitions in a table is 2^31.
