How can I check all the tables in the current database using Oracle?

You can use the following SQL statement to view all tables in the current Oracle database:

SELECT table_name FROM user_tables;

This will return the names of all tables for the current user. To view tables of other users, use the following SQL statement:

SELECT table_name FROM all_tables WHERE owner = '用户名';

Replace “username” with the name of the user you want to view. To view all tables, including system tables and tables from other users, use the following SQL statement:

SELECT table_name FROM all_tables;

This will return the names of all tables.
