Starting in Oracle Database 12c Release 2 it’s now possible to use interval partitioning with list. In the table above, the greatest defined interval is between July 1, 2015 and August 1, 2015. We can evolve our list partition table into an auto-list partition table using a simple alter table command. 1. Partitions in a reference-partitioned table corresponding to interval partitions in the parent table are created when inserting records into the reference partitioned table. In Oracle Database 12c Release 2, you can create a list-partitioned table with two or more columns as partition keys. In 11g this was not supported. The partition and subpartition combination would make a composite-partitioned table—not just a partitioned table—and eliminate the possibility of composite partitioning later. To create a reference-partitioned table, you specify a PARTITION BY REFERENCE clause in the CREATE TABLE statement. External tables, partitioned or non-partitioned, are read only.

If data is loaded into this table with a later date than the greatest defined partition, Oracle will automatically create a new partition for the new month. Auto-List partitioning will automatically create a new list partition for each new value that is encountered. The problem described above can be solved now much easier with one of the new partition features of Oracle Database 12.2. Creating a partitioned table or index is very similar to creating a nonpartitioned table or index. To create a simple multi-column list partitioned table you can issue the following command: rem simple multi-column list partitioned table create table mc (col1 number, col2 number) partition by list (col1, col2) (partition p1 values ( (1,2), (3,4)), partition p2 values ( (4,4)), partition p3 values (default)); Partitioning allows tables, indexes, and index-organized tables to be subdivided into smaller pieces, enabling these database objects to be managed and accessed at a finer level of granularity. Oracle provides a rich variety of partitioning strategies and extensions to address every business requirement. In order to enhance working with reference partitioned tables, three new features have been added in Oracle Database 12c.

When creating a partitioned table or index, you include a partitioning clause in the CREATE TABLE statement. Creating exchange tables in Oracle 12.2. Is there an option how I can create this two dimensional partitioned table with a minimum need of effort if new keys and new dates are inserted? I think by Range and using a date field will work. An enhancement of the CREATE TABLE command allows to create an empty exchange table with the same structure as the source table in one step: CREATE TABLE tmp_sales 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. Hybrid partitioned tables combine the concept of both internal and external partitioned tables. The partitioning clause, and subclauses, that you include depend upon the type of partitioning you want to achieve.
