In oracle 12c , there is option of ‘Automatic’ in partition by list i.e., for any new value for partition key a new partition will be created.

@deepikaaggarwal9930
@deepikaaggarwal9930 5 лет назад
Hi Vivek, Thanks for sharing the videos. These are really helpful to understand the concepts clearly. Using composite partitioning, can also be one of the possible solutions for the problem statement. Like if we use list-range partitioning, in that case, we can create 3 partitions for 3 countries and for each partition we can further create 14 sub-partitions.
@TechCoach
@TechCoach 5 лет назад
Hey Deepika, Yes we can further subpartition based on data and requirement. Though you want to be careful as creating way too many partitions will be difficult to maintain.

What If we use check constraint for region column, is that be good practice sir?
@AnIndianAbroadd
@AnIndianAbroadd 5 лет назад
It is not a good practice, in future if you decide to add a new region you will have to perform a ddl operation to alter the column. I hope this clarifies.

Once again very useful video. But as I can see out of these 9 tutorial video, I think sub-partition is not covered. I haven't seen rest of the videos. It will be very helpful if you add all the topics related to partitioning. Thank you.

Sir one doubt, if I'm not using the partition key in my select Sql will degrade my query performance
@TechCoach
@TechCoach 4 года назад
It will have to do a full table scan instead of a full partition scan unless you have created a global index, in which case the index will be accessed 1st.

@sj9753 4 года назад
Hi.Thanks for the video. I have a doubt regarding global index.you said after deleting partition entire global index will b unusable.If there are 4 partitions,i will drop 3 partitions.That time for the remaining 1 partition how the global index will behave?? Wil it b unusable ??
@TechCoach
@TechCoach 4 года назад
I haven't tried this scenario personally , but I think it will still be unusable.

You should not create partition on staff it will increase the number of objects significantly. I will create a video on dynamic list partitioning next week.

What is staging table and how it is different from normal table ? When we need to use staging table and advantage over it on normal table? Please advise Vivek?
@TechCoach
@TechCoach 3 года назад
Usually staging area or landing area is where you load the data from source without many/any changes. Then you load your final tables from these stage table after the ETL process. I hope this helps Ankur

List partitioning should be used only when the data to be inserted belongs to a specific key! Else you can use default to map unknown values When and why . Data above 2 gb . When predefined set of discrete values to arrange unorganized data in an organized way
