How to find partitioned tables whose loading may fail with ORA-14400 error

Question

Hi,
We have several partitioned tables. Sometimes, when partitions are not created for that month, we get this error
ORA-14400 inserted partition key does not map to any partition
May I know if there is any script or sql which I can use to find out tables which may fail for loading if DBA won't create partitions in next 2 weeks?
Thank You

Sure, you can:
1.Look in DBA_TAB_PARTITIONS by partition_name if you use a particular naming convention, where owner = <your_owner> and table_name = <your_table_name> and partition_name = <your_expected_partition_name>
2. Without going by partition name, you could use dba_tab_partitions and instead check that there is a partition for your table with a high_value you are expecting to use. Be aware that the high_value is a long datatype, so you will likely need to convert it to a varchar2.
3. Before your big load, you could also insert one row into the destination table with the new partition key that will be used, and trap errors with an exception handler. Roll it back if it succeeds.
4. Many partitions could be created in advance to avoid the constant monitoring of new partitions.
5. Or you could also look into switching to interval partitioning if you are on 11g and get out of the business of having to create partitions manually.
