It is constructed from the Connection object. ResultSetMetaDataВ Interface holds information on the types and properties of the columns in a ResultSet. The next() method is used to successively step through the r ows of the tabular results. A ResultSet maintains a cursor pointing to its current row of data. The table rows are retrieved in sequence.

ResultSetВ provides access to a table of data generated by executing a Statement. Statement that is written as String object. Statements and are executed with the method executeUpdate. Note: Statements that create a table, alter a table, or drop a table are all examples of DDL For statements that create or modify tables, the method to use is executeUpdate. For a SELECT statement, the method to use is executeQuery. The Statement class has three methods for executing statements:Д®xecuteQuery(), executeUpdate(), and execute(). Statement interface defines methods that are used to interact with database via the execution of SQL statements. CallableStatement objects are SQL stored procedure call statements.Д®xecuting a SQL statement with the Statement object, and returning a jdbc resultSet. PreparedStatement objects are precompiledД¬allable Statement:В Execute a call to a database stored procedure.Д¬allableStatement prepareCall(String sql) PreparedStatement prepareStatement(String sql) Prepared Statement:В Execute precompiled sql queries with or without parameters. Statement:В Execute simple sql queries without parameters. Statement statement = dbConnection.createStatement() ДЄ statement object is used to send and execute SQL statements to a database. To execute SQL statements, you need to instantiate a Statement object from your connection object by using the createStatement() method. Connection interface defines methods for interacting with the database via the established connection. Once a connection is obtained we can interact with the database. WeвЂ™re using the jdbc odbc subprotocol, so the DriverManager knows to use the .Д¬onnection dbConnection=DriverManager.getConnection(url,вЂќloginNameвЂќ,вЂќPasswordвЂќ)

Each subprotocol has its own syntax for the source.

It also contains methods to deal with transactions. information about the database, tables, and fields. A Connection object provides metadata i.e.

An application can have one or more connections with a single database, or it can have many connections with different databases. Within the context of a Connection, SQL, PL/SQL statements are executed and results are returned. A jdbc Connection represents a session/connection with a specific database. It uses a username, password, and a jdbc url to establish a connection to the database and returns a connection object. Its getConnection() method is used to establish a connection to a database.

DriverManager class manages the JDBC drivers that are installed on the system. DriverManager is considered the backbone of JDBC architecture. The JDBC DriverManager class defines objects which can connect Java applications to a JDBC driver. Class is a class inД¬lass.forName(вЂќвЂќ) //Or any other driver The return type of the Class.forName (String ClassName) method is вЂњClassвЂќ. Since most of the Database servers support ODBC driver therefore JDBC-ODBC Bridge driver is commonly used. A client can connect to Database Server through JDBC Driver. Once loaded, the Driver class creates an instance of itself. In this step of the jdbc connection process, we load the driver class by calling Class.forName() with the Driver class name as an argument. Import java.sql.* The star ( * ) indicates that all of the classes in the package java.sql are to be imported. JDBC Basics вЂ“ Java Database Connectivity StepsД«efore you can create a java jdbc connection to the database, you must first import the We can change database engines without changing database code. JDBC loads a driver which talks to the database.

You will learn how to create a table, insert values into it, query the table, retrieve results, and update the table with the help of a JDBC Program example.ДЄlthough JDBC was designed specifically to provide a Java interface to relational databases, you may find that you need to write Java code to access non-relational databases as well. Because Java can run on a thin client, applets embedded in Web pages can contain downloadable JDBC code to enable remote database access.

It provides RDBMS access by allowing you to embed SQL inside Java code. JDBC is a Java API for executing SQL statements and supports basic SQL functionality. Using JDBC you can send SQL, PL/SQL statements to almost any relational database. The JDBC (Java Database Connectivity) API defines interfaces and classes for writing database applications in Java by making database connections.
