Introduction 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.
Understanding Driver Manager
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.
Understanding Data Source
DataSource object can be thought as a factory for making connections to the particular database that the DataSource instance represents.
Understanding 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.

JDBC Tutorials

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.
First Step towards JDBC
This article introduce you with JDBC and shows you how to create a database application to access the databases.
Accessing 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 Components
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.
Get 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.
Common SQL Commands
SQL commands are divided into categories like DML (Data Manipulation language), DDL (Data definition language), TCL (Tranction control language) and DCL (Data control language).
Using 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.
