What is difference between bulk collect and bulk bind in Oracle?

Bulk binds can improve the performance when loading collections from a queries. The BULK COLLECT INTO construct binds the output of the query to the collection.

How Bulk collect improve performance?

Since the BULK COLLECT fetches the record in BULK, the INTO clause should always contain a collection type variable. The main advantage of using BULK COLLECT is it increases the performance by reducing the interaction between database and PL/SQL engine.

How do I drop a table using execute immediate in Oracle?

What is Pragma Autonomous_transaction?

The AUTONOMOUS_TRANSACTION pragma changes the way a subprogram works within a transaction. A subprogram marked with this pragma can do SQL operations and commit or roll back those operations, without committing or rolling back the data in the main transaction.

Can we use pragma AUTONOMOUS_TRANSACTION in trigger?

Why bulk collect is faster?

When you use bulk binds, you move multiple rows of data from one VM to the other with a single context shift, significantly reducing the number of context shifts, making your code faster.
