I'm new to isqlplus enviroment

Question

after installation, i tried some commands on the sqlplus from the text books though they worked with results on the express edition, but in the enterprise edition none seems to go , i get the error message (error at line 2: ora-00942: table or views does not exist)

Answer 1

the table you want to reference exist in the earlier but doesnot exist in later. to find out the tables in that edition, issue the command below from your sql:
select * from tab order by tabtype;---you see all
or
select * from tab where tname=to_upper('table_name');---replace the table name in quote with the name of your table
