JDBC: New Feature

Jdbc New Features

The latest version of JDBC is 4.0 currently. Java has updated jdbc api to ease and simplify the coding to database interactivity.

Here, we are going to see the features included in Jdbc 3.0 and Jdbc 4.0.

Jdbc 3.0 Features

The important features of JDBC API 3.0 are as follows:

  • Jdbc RowSet We have done the great discussion on JdbcRowSet in the previous page.
  • Savepoint in transaction management Now you are able to create, rollback and release the savepoint by Connection.setSavepoint(), Connection.rollback(Savepoint svpt) and Connection.releaseSavepoint(Savepoint svpt) methods.
  • Statement and ResultSet Caching for Connection Pooling Now you are able to reuse the statement and result set because jdbc 3 provides you the facility of statement caching and result set caching.
  • Switching between Global and Local Transactions
  • Retrieval of auto generated keys Now you are able to get the auto generated keys by the method getGeneratedKeys().

Jdbc 4.0 Features

The important features of JDBC API 4.0 are given below:

  • Automatic Loading of Driver class You don't need to write Class.forName() now because it is loaded bydefault since jdbc4.
  • Subclasses of SQLException Jdbc 4 provides new subclasses of SQLException class for better readability and handling.
  • New methods There are many new methods introduced in Connection, PreparedStatement, CallableStatement, ResultSet etc.
  • Improved DataSource Now data source implementation is improved.
  • Event Handling support in Statement for Connection Pooling Now Connection Pooling can listen statement error and statement closing events.

Difference between net platform and dot net framework...

Difference between net platform and dot net framework... .net platform supports programming languages that are .net compatible. It is the platform using which we can build and develop the applications. .net framework is the engine inside the .net platform which actually compiles and produces the executable code. .net framework contains CLR(Common Language Runtime) and FCL(Framework Class Library) using which it produces the platform independent codes. What is the .NET Framework? The Microsoft .NET Framework is a platform for building, deploying, and running Web Services and applications. It provides a highly productive, standards-based, multi-language environment for integrating existing investments with next-generation applications and services as well as the agility to solve the challenges of deployment and operation of Internet-scale applications. The .NET Framework consists of three main parts: the common language runtime, a hierarchical set of unified class librari...

Standard and Formatted Input / Output in C++

The C++ standard libraries provide an extensive set of input/output capabilities which we will see in subsequent chapters. This chapter will discuss very basic and most common I/O operations required for C++ programming. C++ I/O occurs in streams, which are sequences of bytes. If bytes flow from a device like a keyboard, a disk drive, or a network connection etc. to main memory, this is called   input operation   and if bytes flow from main memory to a device like a display screen, a printer, a disk drive, or a network connection, etc., this is called   output operation . Standard Input and Output in C++ is done through the use of  streams . Streams are generic places to send or receive data. In C++, I/O is done through classes and objects defined in the header file  <iostream> .  iostream  stands for standard input-output stream. This header file contains definitions to objects like  cin ,  cout , etc. /O Library Header Files There are...
