What are the steps for importing data in PL/SQL?

The steps for importing data in PL/SQL are as follows:

1. Create a table to store the data to be imported, ensuring that the structure of the table matches the structure of the data to be imported.
2. You can import data by using either the SQLLoader tool or by using PL/SQL code. SQLLoader is a tool provided by Oracle for importing large amounts of data, using a control file to specify the data source and target table. Importing data using PL/SQL code would require writing your own data insertion statements.
3. When importing data using PL/SQL, you can use the INSERT INTO statement to insert data. This statement requires specifying the table name, column names, and the values to be inserted.
4. Before importing data, it is beneficial to create indexes or constraints on tables to enhance query performance and ensure data integrity.
5. After importing the data, you can use the SELECT statement to query the newly imported data to verify that it has been successfully imported.
