Tables are database objects that contain all the data in a database.In tables, data is logically organized in a row-and-column format similar to a spreadsheet.After you create a table, you insert rows of data using SQL statements or using an Oracle bulk load utility.Table data can then be queried, deleted, or updated using SQL.As with Oracle 11g you first install the patch into the Oracle Home with all services & databases down.But with Oracle Database 12c after restarting the database simply run datapatch from the OPatch directory: Given that patching is a two-step process, some common DBA questions are:1) Has a patch been installed in a given database?For more information, see Partitioned Tables and Indexes.
The fields in the Customers table consist of Customer ID, Customer Name, Contact Name, Address, City, Postal Code and Country.
RDBMS stands for Relational Database Management System.
RDBMS is the basis for SQL, and for all modern database systems such as MS SQL Server, IBM DB2, Oracle, My SQL, and Microsoft Access.
Oracle Database 12c brings us many new features including: the long needed ability to run OPatch and query the patch software installed in the Oracle Home programatically through SQL using the new DBMS_QOPATCH package.
If you’re a DBA working in an environment where patching consistently among databases is important, this is a welcomed enhancement.
