Global temporary table is a temporary table once if the action is done it will automatically get closed best example is ticket booking in app (if the end user books the ticket in app that session is blocked once the transaction has done and that particular seat will not shows to other user Evan if the transaction is not completed after that end user left the app then that session will get closed its called global temporary table)
This index is on NUMBER datatype column. What if we create a index on VARCHAR2 datatype column? How it will create a B- Tree then? Could you please explain?
my question is how the root node selected by oracle for index creation if root node selection based on the median value then in case of live system data is continuously inserted into the table so each time there will be a change in the median which means a change in root node value.
Hello sir, the b-tree graph that you are using in this tutorial is unbalanced, and b-tree will never be unbalanced. btree have some property. Property #1 - All the leaf nodes must be at same level. Property #2 - All nodes except root must have at least [m/2]-1 keys and maximum of m-1 keys. Property #3 - All non leaf nodes except root (i.e. all internal nodes) must have at least m/2 children. Property #4 - If the root node is a non leaf node, then it must have at least 2 children. Property #5 - A non leaf node with n-1 keys must have n number of children. E.T.C.
Sir, I have been asked by the interviewer many times about Local and Global indexes? What we can say when they have asked about Local and Global indexes. When the indexes become Local and Global.. Please clarify on this?
Hello Sir, Nice explanation. I have some doubts: 1. How that main index root node is decided to be 3000? 2. Does Btree indexing sorts the column values at the time of index creation within itself because salary column is majorly non-sorted column and Btree seems applicable on sorted records only? Please clarify. Thanks!
