Answer: There are a few ways to verify whether a table exists within Oracle. One way is to describe it to check if the table exists: SQL> desc mytable. Another is to select the first row to check that the table exists (hey it may have millions of rows!): SQL> select * from mytable where rownum=1; At bare minimum, you will get a response of 0 rows selected which means the table exists, but there is no data in the table. You can also check the data dictionary to see if a table exists: SQL> select table_name from user_tables where table_name='MYTABLE';
Oracle NoSQL Database. Data is stored as key-value pairs, which are written to particular storage node(s), based on the hashed value of the primary key. Storage nodes are replicated to ensure high availability, rapid failover in the event of a node failure and optimal load balancing of queries. Customer applications are written using an easy-to-use Java/C API to read and write data. The Oracle NoSQL Database is a distributed key-value database. It is designed to provide highly reliable, scalable and available data storage across a configurable set of systems that function as storage nodes. Oracle NoSQL Driver links with the customer application, providing access to the data via appropriate storage node for the requested key.
