Oracle cursor for updating in oracle


You also have support for the Database Change Notification feature of Oracle Database.These new features are discussed in details in "Database Administration".This package consists primarily of classes that provide Java mappings to SQL data types and their support classes. Instead, the database table stores a locator that points to the location of the actual data. Because Java representation of these data types requires time zone information that is obtained dynamically from the server and cached on the client side.Both the Oracle JDBC Oracle Call Interface (OCI) driver and the Oracle JDBC Thin driver support DML returning. RAW These classes hold primitive SQL data types in Oracle native representation.package supports direct access to data in SQL format. BFILE Binary large objects (BLOBs), character large objects (CLOBs), and binary files (BFILEs) are for data items that are too large to store directly in a database table. In most cases, these types are not used internally by the drivers and you should use the standard JDBC types instead.Oracle JDBC uses these type maps to determine which Java class to instantiate and populate when it retrieves Oracle object data from a result set. To specify an object type in JDBC, use its fully qualified name.


Oracle provides Java classes and interfaces that extend the Java Database Connectivity (JDBC) standard implementation, enabling you to access and manipulate Oracle data types and use Oracle performance extensions.This chapter provides an overview of the classes and interfaces provided by Oracle that extend the JDBC standard implementation.
