What are the different ways to import data in PL/SQL?

There are several ways to import data in PL/SQL.

1. You can use the INSERT statement to directly insert data into a table, either one row at a time or multiple rows at once.
2. By using the BULK COLLECT statement, you can extract multiple rows of data from one table into an array variable all at once, and then insert that array into another table.
3. By using the FORALL statement, multiple rows of data can be inserted into the table at once, instead of inserting each row one by one in a loop.
4. The INSERT INTO SELECT statement allows you to insert data from one table into another table and you can use a WHERE clause to select the data to insert.
5. Utilize external tables: External tables are a unique type of table that do not store actual data but instead reference external data files. Data from an external table can be imported into a regular table using the CREATE TABLE AS SELECT statement.
6. Utilize the Data Pump tool: Data Pump is an Oracle tool used for importing and exporting data, and it can be invoked to import data using PL/SQL scripts.
