How to view sequences in PL/SQL?

To view PL/SQL sequences, you can use one of the following methods:

1. Connect to the database using database tools like SQL*Plus or SQL Developer, and execute the following SQL statement:

SELECT sequence_name, last_number 
FROM user_sequences;

This statement will display the names and current values of all sequences under the current user.

1. To view sequences of other users, you can use the following SQL statement:

SELECT sequence_name, last_number 
FROM all_sequences
WHERE owner = '用户名';

Replace “username” with the name of the user whose sequence you want to view.

1. To view all sequences in a database, including those owned by all users, you can execute the following SQL statement:

SELECT sequence_name, last_number 
FROM dba_sequences;

Please note that executing this query may require administrator privileges.

No matter which method is used, you can obtain the name and current value of the sequence.
