Sometimes, because of a sudden power outage or other reason, PL/SQL It cannot even display, sequence, and other elements in a database table. Use SQL Windows to run queries for general queries, logins, or the same phenomenon again.

I am not able to solve the problem because of the repeated login guess is that plsql login history. It cleared the account login history. Detailed procedures, such as the following:

Tools--"preferences--" Login history —————— Delete account login History

This can also be done through, for example, the following operation portals:

Delete the login history of the account and log in again, and you'll find that you've been looking for a table, sequence, and so on.
