What are the equivalent of Rdb's SHOW commands in SQLPLUS?

Typically in SQLPLUS you are required to interrogate tables to understand metadata objects.  There are a set of tables usually prefixed  ALL_ or USER_. Unless you want to look specifically within your own schema use the ALL_ tables.  It may be necessary to prefix ALL_ with SYS.ALL_.

An RDB database is usually single schema whereas an RDBMS will always be multi-schema with references to OWNERs.  See SQL(PLUS)>select username from all_users where username != 'SYS' and username != 'SYSTEM';

Because of the length of some columns it may be necessary to use the following commands to improve the display in sqlplus for example:

The purpose of this article is to list commands that would be useful in understanding objects related to tables. These include the following:

A) SQL> SHOW TABLES

B) SQL> SHOW TABLE(COLUMN) <TABLE_NAME>

C) SQL> SHOW INDEX

D) SQL>SHOW INDEX <INDEX_NAME>  

E) SQL> SHOW TABLE(INDEX) <TABLE_NAME>

F) SQL> SHOW TABLE(COMMENT) <TABLE_NAME>

G) SQL> SHOW VIEWS

H) SQL> SHOW VIEW <VIEW_NAME>

I) SQL> SHOW TABLE(CONSTRAINT) <TABLE_NAME>

J) SQL> SHOW PROTECTION ON TABLE <TABLE_NAME>

K) SQL> SHOW PROTECTION ON DATABASE RDB$DBHANDLE;

L) SQL> SHOW TRIGGERS 

M) SQL> SHOW TRIGGER <TRIGGER_NAME>

N) SQL>SHOW TABLE(TRIGGER) <TABLE_NAME>

O) SQL>SHOW SEQUENCE
