ResultSet rs=stmt.executeQuery("select * from TABLE_DEMO")
In this step, we execute the query using executeQuery()method that returns the object of ResultSet. PreparedStatement pstmt=con.prepareStatement("insert into TABLE_DEMO values(?,?)") Suppose, if we have parameterized queries we use PreparedStatement Interface. Here Statement is an interface that contains all the methods to execute queries with the database. getConnection(String url, String username, String password) Connection con=DriverManager.getConnection(.getConnection(String url, Properties info).A connection is an interface to keep the session between java application & database. There are the following 3 ways we can call. We can create a connection by calling the getConnection () method of DriverManager class. As it is a static method so, we are calling with the Class Name. We have a method forName()of Class class which is a static method and is used to register the drivers.

Add the jar file for mysql-connector.jar(open directory of MySQL where you have installed >open Connector >copy mysql-connector-java8.0.21 into lib folder) Register the Driver.Create a project in eclipse (as we normally create it).If you are adding jar files just follow these steps. If you are creating Maven Project you just need to add the following dependencies inside pom.xml file. There are certain steps to be followed to connect using JDBC (In this we will connect our Program with MYSQL database). Thin Driver: It converts the JDBC method to the vendor-specific database using thin drivers. Network Protocol driver: It converts the JDBC method to the vendor-specific database using a Middleware application.

The disadvantage here is we need to install the native drivers. Native API driver: It converts the JDBC methods into Native database API. JDBC-ODBC Bridge Driver: It uses ODBC Driver that is in the class. So, Java provides us some classes for JDBC which are present in the java.sql or javax.sql package. So, Sun Microsoft System on February 19, 1997, released JDBC and that has its JDBC API. (Here, API stands for Application Programming Interface which lets us access data and functions of another application, services, or OS).īefore JDBC we had ODBC that stands for Oracle Database Connectivity which was platform-specific and was written in C language. In java, when we work with an application that needs access to the database, we need some interface to connect our Java programming with the database. JDBC is a Java Database Connectivity that provides an API to connect the client with the database. New Projects in Java Using JSP, Servlet, JDBC and MYSQL What Is JDBC?
