In PL/SQL, SQL*Plus tool can be used to import large SQL files.

To import a large SQL file, follow these steps:

  1. Open a command line terminal or SQL*Plus tool.
  2. Log in to the database using the following command:
sqlplus username/password@database

username is your database username, password is your password, and database is your database connection string.

  1. Switch to batch mode in SQL*Plus using the following command:
set serveroutput on
set define off
  1. Use the following command to import the SQL file into the database:
@path_to_sql_file

Among them, path_to_sql_file is the path to the large SQL file.

  1. Please wait for the import process to complete. The import process may take some time depending on the size and complexity of the SQL file.
  2. After the import is complete, you can use the following command to exit SQL*Plus:
exit

Please be aware that the import process may involve accessing permissions and limitations of the database. Make sure you have sufficient permissions to carry out the import operation, and it is advisable to back up the database before executing the import operation to prevent any unexpected situations.
