1. In SQLPLUS, just use DESC[ribe] tablename.

2. When an external application calls to view the table structure in ORACLE, the following statement can only be used instead:

1. Look at the field name and data type  




--(user_tab_columns abbreviation cols)
2. View all columns


3. View certain columns


4. View the data types of the specified columns


5. View all constraints through user_constraints   


6. View the primary key constraints:
