Oracle SQL By Example
To retrieve a list of user tables in Oracle SQL, you can use the following query:
SELECT table_name FROM user_tables;
This query will return a list of all tables owned by the current user in the Oracle database. You can run this query in SQL Developer or any other SQL client connected to your Oracle database to see the user tables. Additionally, you can also use the ALL_TABLES view to view tables accessible to the current user, or the DBA_TABLES view to see all tables in the database, regardless of the owner.
How to get information about user tables in Oracle SQL?
You can get information about user tables in Oracle SQL by querying the USER_TABLES data dictionary view. This view contains information about all tables owned by the currently logged-in user.
You can use the following query to retrieve information about user tables:
SELECT table_name, tablespace_name, num_rows, blocks, avg_row_len FROM user_tables;
This query will return the table name, tablespace name, number of rows, number of blocks, and average row length for each table owned by the current user.
Additionally, you can also query the ALL_TABLES data dictionary view to get information about all tables accessible to the current user, including those owned by other users.
SELECT table_name, owner, tablespace_name, num_rows, blocks, avg_row_len FROM all_tables;
Keep in mind that the information retrieved from these data dictionary views may vary depending on the privileges granted to the current user.
