After a table is created, you can use an SQL statement to view the creation statement that defines the table.
MySQL mode
In MySQL mode, you can use the SHOW CREATE TABLE statement to view the definition of a table.
Example:
obclient> SHOW CREATE TABLE test;
Oracle mode
In Oracle mode, you can use the following statement to view the definition of a table:
obclient> SELECT dbms_metadata.get_ddl( 'TABLE', 'TEST', 'SYS' ) FROM DUAL;
