reference partitioning in oracle

Interval Reference Partitioning. Namely, LineItems.order_id references Orders.order_id. This is an example for the 12c new feature of creating interval partitioned tables as parent tables for reference partitioning. The new 11g Reference Partitioning option requires a foreign key on the child table, which requires a unique key on the parent table. Using reference partitioning, a child table can inherit the partitioning characteristics from a parent table. If data in multiple tables has a related life cycle, then reference partitioning can provide significant manageability benefits. But in Oracle 12c, you can now split a partition into multiple partitions. Another new partitioning capability is the use of reference partitioning on tables that employ interval partitioning.

Reference Partitioning. Example 4-8 Creating reference-partitioned tables. Reference partitioning allows you to create a partition based on a column that is not in the table being partitioned, but rather is a foreign key reference to a different table.

It generates drop table TABLE_NAME cascade constraints purge lines for all tables, amongst other object types, by looping through user_objects.. Create new tables with partition by reference (including primary key on parent table and foreign key on child tables as this is required by partition by reference) Copy data from old to new tables; Create other indexes and constraints; Gather statistics on the new tables; Drop old tables The benefit of this extension is that tables with a parent-child relationship can be logically equipartitioned by inheriting the partitioning key from the parent table without duplicating the key columns. To create a unique key on a partitioned table, you either need to include the partitioning key to get a local index, or end up with a global index. 5.1 - Transition point.

That partition needs to be 'split', and this split can create only two partitions out of one at a time (unless DB is oracle 12c), so multiple splits needs to be run and each split is full scan on the partition. Hi,This is the scenario:Consider Parent_table that is list partitioned based on dept_no - with partition_name specified as 'P_Dept_no'.Parent_table -> Child_table_1 (reference_partitioned based on Parent_Table) -> Child_table_2 (reference_partitioned based on Child_Table_1) -> Child_Table_3 You can use following different types of Partitioning in Oracle database.

The logical dependency also automatically cascades partition maintenance operations, thus making application development easier and less error-prone. Using reference partitioning, a child table can inherit the partitioning characteristics from a parent table. The child table is partitioned using the same partitioning key as … Example 4-8 creates a parent table orders which is range-partitioned on order_date. In other words, the table should be a partitioned table already. Oracle Database 11g provides a very useful new feature: referential partitioning.

If a partition is not explicitly named, then it inherits its name from the corresponding partition in the parent table, unless this inherited name conflicts with an existing explicit name. You can/should rename them later if such a need arises. Hi Tom Can a reference partition be added to a table using ALTER TABLE statement after the child table has been created assuming the Parent Table exists with the partitions. This clause specifies the name of a referential constraint and this constraint becomes the partitioning referential constraint that is used as the basis for reference partitioning in the table. Personally I see no need in renaming them. Oracle Database SQL Language Reference for syntax of nested tables. If partition descriptors are provided, then the number of partitions described must exactly equal the number of partitions or subpartitions in the referenced table. Viewed 2k times 2.
