WRITE: SELECT * FROM tabs; It will show you all the tables from the data base (system created and also user created). If you see a dollar ($) sign in a table name then its a system table else it's created by the user.

varchar supports 2000 characters where varchar2 supports 4000 character.

If you look deep into it, it is for saving memory. If you write varchar(30) and entered just 10 character all the remaining character will be set as NULL characters it will not be deleted or freed. On the other hand, if you declare varchar2(30) and entered just 10 characters all the remaining characters will be deleted or freed.

char supports only 255 characters where varchar2 supports 2000 characters, varchar used for another version of SQL such as MySql
Anadi Sharma (4 months ago)
There's no difference between varchar and varchar2. It's just in oracle there's a versioning in varchar2.
