JDBC - Java Database Connectivity Tutorials
Java Database Connectivity or in short JDBC is a technology that enables the java program to manipulate data stored into the database. Here is the complete tutorial on JDBC technology.
JDBC is Java application programming interface that allows the Java programmers to access database management system from Java code. It was developed by JavaSoft, a subsidiary of Sun Microsystems.
Components of JDBC
JDBC is consists of four Components: The JDBC API, JDBC Driver Manager, The JDBC Test Suite and JDBC-ODBC Bridge.
JDBC is an API specification developed by Sun Microsystems that defines a uniform interface for accessing various relational databases. JDBC is a core part of the Java platform and is included in the standard JDK distribution.
Driver and Its Types
The JDBC DriverManager class defines objects which can connect Java applications to a JDBC driver. DriverManager has traditionally been the backbone of the JDBC architecture. It is quite small and simple.

An important part of every business is to keep records. We need to keep records of our customers, the employees of our company, the emails etc. A Relational model is the basis for any relational database management system (RDBMS).
Common SQL Statements
This section describes SELECT, INSERT, UPDATE and DELETE statements.
This section introduces you with Transactions, logging, isolation and concurrency concepts.
to the java.sql Package
This package provides the APIs for accessing and processing data which is stored in the database especially relational database by using the java programming language. It includes a framework where we different drivers can be installed dynamically to access different databases especially relational databases.
The main responsibility of JDBC database driver is to load all the drivers found in the system properly as well as to select the most appropriate driver from opening a connection to a database. The Driver Manager also helps to select the most appropriate driver from the previously loaded drivers when a new open database is connected.
DataSource object can be thought as a factory for making connections to the particular database that the DataSource instance represents.
the Connection Object
A Connection object represents a connection with a database with a database. When we connect to a database by using connection method, we create a Connection Object, which represents the connection to the database.

This can be done very easily , and in this section we are going to do the same that is, how to delete a specific row from a specific database table.
Join tables in the specific database
In this section, we are going to consider how to join two or more tables in a specific database. For this you need to have two or more table in the database. If two or more tables are available in the database then Join operation is performed otherwise not.
Join tables with the NATURAL LEFT JOIN operation
This section describes the NATURAL LEFT JOIN operation and how to retrieve data through it. In this operation we are going to retrieve data according to match the field name of another tables.
Join tables with the NATURAL RIGHT JOIN operation
This section describes the NATURAL RIGHT JOIN operation of table in a specific database. This operation join tables on the basis of matching fields but priority will be given to the right table field values.
Cross Join Tables in a Specific Database
This section introduces you to the cross join between two tables. The cross join operation retrieves data between two tables as a Cartesian product of set theory in mathematics. All data show to multiply by each rows.
- JDBC (Java Database Connectivity) -Tutorials
JDBC is essentially an Application Programming Interface (API) for executing SQL statements, and extracting the results. Using this API, we can write database clients, such as Java applets, servlets and Enterprise JavaBeans, that connect to a relational database, such as Oracle, MySQL, Sybase, Informix, Ingres, PostgreSQL, or any other database that implements this API, execute SQL statements, and process the results extracted from the database.

This article introduce you with JDBC and shows you how to create a database application to access the databases.
the Database from Servlet
This article shows you how to access database from servlets. Here I am assuming that you are using win95/98/2000 and running Java Web Server.
JDBC stands for Java Database Connectivity. For connectivity with the database we uses JDBC. It establish connection to access the database. This provides a set of classes in the java.sql package for Java applications to communicate with databases.
Column Count using ResultSet in SQL
This example counts the number of columns in a table. The ResultSetMetaData interface can be used to get type and properties information of columns in a ResultSet.
SQL commands are divided into categories like DML (Data Manipulation language), DDL (Data definition language), TCL (Tranction control language) and DCL (Data control language).
JOINING Operation in JDBC
Whenever we need to select data from two or more tables, we have to perform a join operation. Tables in a database can be related to each other with keys.
- Using WHERE
Clause in JDBC
Where clause is used to retrieve the data from a table based on some specific conditions. It allows to filter the data from a table, a WHERE clause can be added to the SELECT statement.
- Using Select
Statements in JDBC
The SELECT statement is used to select data from a table. For terminating a statement, semicolon is used. When we want to fetch the data from any table then we have to use SELECT statement.
