About SQL Plus/PL

A problem with a headache, eventually solved, or because the Oracle is not enough to understand.

The table space was initially created in PL/SQL, the user was created, and DBA authority was granted. The table is then built, the data is inserted, but the table is not visible in SQL Plus and the error is directly. The reverse operation also does not find a table in SQL Plus in PL/

The reason is simple, I create a user in PL/SQL, Grant DBA authority, when logged in the user is the SYSDBA category login, look up the table when you need to use the format usr. If you change to normal when you log in, this problem will not occur. Oracle's user structure and table structure are tree-like and need to be well understood. There is also a command in PL/SQL if you need to sync with the plus or click Submit.

What a simple question ah, but engaged for a long while, is also drunk.
