create table with sequence in oracle

The sequence object generates a number sequence.

In addition, it invalidates all objects that depend on the renamed table such as views, stored procedures, function, and synonyms. Red Hat Enterprise Linux (RHEL) is the world's leading open source operating system that provides an intelligent, stable, and security-focused foundation for modern, agile business operations. Use the DUPLICATE command to create a copy of a source database.RMAN can create either of the following types of databases: A duplicate database, which is a copy of the source database (or a subset of the source database) with a unique DBID.Because a duplicate database has a unique DBID, it is independent of the source database and can be registered in the same

Categories that behave like the java.lang.Character boolean ismethodname methods (except for the deprecated ones) are available through the same \p{prop} syntax where the specified property has the name javamethodname. In addition, it invalidates all objects that depend on the renamed table such as views, stored procedures, function, and synonyms.
