show existing tables in database

I usually work with MySQL databases. I need to move one of our web applications into an Oracle database. All I need to know is how I can display all existing tables in a database that I created.

In MySQL all I have to type in is :

SQL> show tables;

It does not seem to be this simple in Oracle.
Someone please help thank you.

You can query either of the 2 data dictionary tables
user_tables or all _tables depending on whether you want to see
the tables you own or the tables you have access to

SQL> select table_name from user_tables;

Hi,

In Oracle you can execute:

> spool c:/tables.sql
> SELECT OWNER,OBJECT_TYPE,OBJECT_NAME
FROM DBA_OBJECTS
WHERE OWNER NOT IN ('SYS','SYSTEM');
> spool off

This statement generate a file i.e tables.sql in drive c that contain all object in your database except that from users sys and system (superusers in Oracle).

Hope this helps

SQL> select table_name from user_tables;

This syntax worked. But also what I found to work is this :

SQL> select tname from tab;

Thank you all for your help.
