How can I quickly import a large amount of data in PL/SQL?

To quickly import a large amount of data into PL/SQL, you can utilize the following methods:

1. Using INSERT statement: Insert multiple rows of data at once using the INSERT statement. You can write a script containing multiple INSERT statements, with each INSERT statement inserting a single row of data. Then execute the script.
2. Using the FORALL statement: The FORALL statement is a bulk operation statement in PL/SQL that allows multiple rows of data to be inserted at once. You can use an array to store the data to be inserted, and then use the FORALL statement to insert the entire array into the target table.
3. PL/SQL supports the concept of external tables, allowing you to import data directly into the database by defining an external table using the CREATE TABLE statement. You can specify the location and format of the external data file. After that, you can use the INSERT statement to import data from the external table into the target table.

No matter which method you choose, you should select the appropriate one based on the size of the data and performance requirements.
