Great! I need to have replay that one. This opens some new possibilities. I could even correct some suboptimal database design and/or add partitioning. Need some study and testing though.

I would suggest mentioning early on the view video which dialect of SQL or platform you are on as the details vary between Oracle, SQL Server, MySQL, PostgreSQL, etc.

Hello. Cool. Everything is ok with INSERT. But how does it work with DELETE, UPDATE? After DELETE a row from a table select /*+ fresh_mv */ from my_mv query returns ORA-32358

use dbms_mview.explain_mview to see if you need to add anything to the mview log
