I am learning oracle sql. I downloaded sql command line on my laptop. I have an oracle account. I used connect username/password;
to connect to sql first, it failed (I did some searches on google, someone says it might be something wrong with my username or password, because it has special character (e.g. @) in it). Then I tried connect sys/root as sysdba;
, it worked.
After connecting to the server, I started putting my sql schemas in and populated them. Everything works fine.
My problem is when I tried to use the data I have already populated the next day they are all gone but the table still remains. How could I store my data when I close the software?
