I. Course theme
Take everyone to practice hand in hand, and improve yourself in practice
Take you hand in hand to learn the ocm course of oracle 19. After learning this course, you can effectively improve the 3-5 level of oracle database.
And some actual combat videos and knowledge points can not be found in the market, such as actual combat 16
This practical course is broad, deep and refined. It can solve 96% of the students' database migration, upgrading and optimization problems.
If after watching all the videos, you think what I said is average, and the course is not as good as what I said, you can find customer service, return the original price to you, and let you go whoring for nothing.
If you think you speak well, with depth, breadth and precision, please leave your valuable feedback and evaluation so that I can further improve myself.
Recently, some students reported that the documents were incomplete, so I sorted them out again.
In addition, the training documents for SQL optimization and database upgrade of the original Oracle engineers in 2023 will be uploaded.
The original factory upgrade training video can alone Find me.

1-where a like '% hello%' How to walk the index (involving full-text indexing and scheduled jobs)
2-where a like '% hello' How to go to the index
3 - Production practice, business requirements are as follows
A table 200G contains the data of the last five years. The table contains clob fields. Through query, it is found that clob fields occupy 190G of space.
The consulting business found that this table only has insert operations, and it can only retain the production data of the last three months.
The solution is as follows.
3-1 Use online redefinition to modify this table to be a partition table and an interval partition table.
3-2 Compress the clob field of the table in the process of online redefinition (the actual combat shows that the 100G table is about 10G after compression)
3-2 Because this table needs to be redefined online as an interval partition table, but this table does not have a time column, it needs to create a virtual column of the table.
3-4 After online redefinition as interval partition, delete the partition before 3. Pay attention when deleting, otherwise the table index is easy to invalidate
3-5 What should be paid attention to in the online redefinition process (there is extra space, there is extra temporary space, and the fields of the interval partition cannot have null values)
3-6 What is the difference between interval partition and range partition? Can they be converted to each other?

This practical course will be updated from time to time. After summarizing the practical operations in the production process, it will be explained to everyone. At the same time, it is also a form of precipitation and accumulation of knowledge. During the irregular update process of the video, the chapters may be confused. After the video update is completed, the chapters will return to normal. I hope my video can help you. We can also communicate with each other at any time about the problems encountered in the actual combat. I look forward to your valuable comments and true ideas, so that I can provide you with better and better content in the future recording.
