MySQL Java Connector
Java Connector
MySQL provides connectivity for Java customer applications with MySQL Connector/J, a driver that implements the Coffee Database Connectivity (JDBC) API. The API is the industry standard for database-independent connectivity between the Java programming language and a wide range of – SQL databases, spreadsheets etc. The JDBC API tin exercise the following things :
- Establish a connection with a database or access any tabular data source.
- Ship SQL statements.
- Retrieve and process the results received from the database.
In the post-obit department, nosotros have discussed how to install, configure, and develop database applications using MySQL Connector/J (JDBC driver).
MySQL Connector/J version :
| Connector/J version | JDBC version | MySQL Server version | Status |
|---|---|---|---|
| 5.i | 3.0, 4.0 | four.one, five.0, 5.ane, five.five, v.6, 5.7 | Recommended version |
| v.0 | 3.0 | iv.ane, five.0 | Released version |
| three.1 | three.0 | four.ane, v.0 | Obsolete |
| 3.0 | 3.0 | three.x, 4.one | Obsolete |
Download Connector/J :
MySQL Connector/J is the official JDBC commuter for MySQL. You lot can download the latest version of MySQL Connector/J binary or source distribution from the following web site -
http://dev.MySQL.com/downloads/connector/j/
For Platform Independent select any i from the following :
For Microsoft Windows :
Installation
You tin install the Connector/J package drivers using either the binary, binary installation or source installation. The binary method is easy which is a bundle of necessary libraries and other files pre-built, with an installer plan. The source installation method is of import where you lot want to customize or modifies the installation procedure or for those platforms where a binary installation bundle is not available. Apart from that solution, you manually add the Connector/J location to your Java classpath.
MySQL Connector/J is distributed every bit a .zip or .tar.gz archive containing the sources, the class files. After extracting the distribution archive, you lot can install the driver by placing MySQL-connector-coffee-version-bin.jar in your classpath, either by adding the full path to information technology to your classpath environment variable or by direct specifying information technology with the control line switch -cp when starting the JVM.
You can set the classpath environment variable under Unix, Linux or Mac OS X either locally for a user within their .profile, .login or another login file. You can as well fix it globally by editing the global /etc/profile file.
For case add the Connector/J commuter to your classpath using one of the following forms, depending on your command shell :
# Bourne-compatible shell (sh, ksh, bash, zsh): shell> consign CLASSPATH=/path/MySQL-connector-coffee-ver-bin.jar:$CLASSPATH # C shell(csh, tcsh): beat out> setenv CLASSPATH /path/MySQL-connector-java-ver-bin.jar:$CLASSPATH
In Windows 2000, Windows XP, Windows Server 2003 and Windows Vista, you can set up the surroundings variable through the System Control Panel.
Install Java Connector on Microsoft Windows
Select and download the MSI installer packages from http://dev.MySQL.com/downloads/connector/j/ as per your requirement.
Now follow the following steps :
Step -1 :
Double click the installer (hither it is "MySQL-connector-java-gpl-v.ane.31.msi")
Pace -2 :
Click on 'Run' and complete the process.
Connecting to MySQL using MySQL Connector/J
The following case shows how to connect/stop and handle errors. (Coffee version seven Update 25 (build ane.7.0_25-b16))
import java.sql.Connection; import coffee.sql.DriverManager; import java.sql.SQLException; public form examination { public static void main (String[] args) { Organization.out.println("\n\n***** MySQL JDBC Connection Testing *****"); Connection conn = aught; try { Class.forName ("com.MySQL.jdbc.Driver").newInstance (); String userName = "root"; String password = "pqrs123"; String url = "jdbc:MySQL://localhost/sakila"; conn = DriverManager.getConnection (url, userName, countersign); System.out.println ("\nDatabase Connexion Established..."); } catch (Exception ex) { System.err.println ("Cannot connect to database server"); ex.printStackTrace(); } finally { if (conn != null) { attempt { System.out.println("\n***** Let terminate the Connection *****"); conn.close (); System.out.println ("\nDatabase connection terminated..."); } catch (Exception ex) { System.out.println ("Mistake in connectedness termination!"); } } } } } Caption:
To create a java jdbc connexion to the database, you must import the following coffee.sql package.
- import coffee.sql.Connection;
- import java.sql.DriverManager;
- import java.sql.SQLException;
At present we will brand a class named 'test' and and then the primary method.
To create a connection to a database, the code is :
conn = DriverManager.getConnection (url, userName, password);
The JDBC DriverManager class defines objects which can connect Java applications to a JDBC driver. DriverManager is the backbone of the JDBC architecture. The DriverManager has a method called getConnection(). The method uses a jdbc url, username and a password to establish a connection to the database and returns a connection object. We take used the following url, username and countersign in the above code.
- The url string is "jdbc:MySQL://localhost/sakila" where the first function "jdbc:MySQL://localhost" is the database blazon (hither it is MySQL) and server (here information technology is localhost). Rest part is the database proper noun (hither information technology is 'sakila').
- The user proper name for MySQL is defined within the variable 'userName'.
- The countersign for MySQL is divers within the variable 'password'.
The DriverManager attempts to connect to the database, if the connexion is successful, a Connection object is created, (hither information technology is called 'conn') and the program will display a message "Database Connection Established..."
If the connection fails (e.g. supplying wong password, host address etc.) then you need to handle the situation. Nosotros are trapping the mistake in catch part of the endeavour … catch statement with appropriate messages and finally close the connection.
Compile and Run it
Assume that 'examination.java' is stored in E:\ and 'MySQL-connector-java-v.1.31-bin.jar' is stored in "C:\Programme Files\MySQL\MySQL Connector J\".
Note : The class path is the path that the Coffee Runtime Environment (JRE) searches for classes and other resources files. You tin can alter the class path by using the -classpath or -cp option of some Java commands when y'all call the JVM or other JDK tools or by using the classpath environment variable.
Querying data using MySQL Connector/J
Suppose we want to become the names (first_name, last_name), salary of the employees who earn more than than the average salary and who works in whatsoever of the IT departments.
Structure of 'hour' database :
Sample table : employees
SQL Code :
SELECT first_name, last_name, bacon FROM employees WHERE department_id IN (SELECT department_id FROM departments WHERE department_name Like 'Information technology%') AND salary > (SELECT avg(salary) FROM employees); Here is the Coffee Code (version 7 Update 25 (build 1.seven.0_25-b16))
import java.sql.Connection; import coffee.sql.DriverManager; import java.sql.SQLException; import java.sql.Argument; import java.sql.ResultSet; public class testsql { public static void principal (Cord[] args) { Connexion conn = null; effort { Course.forName ("com.MySQL.jdbc.Driver").newInstance (); String userName = "root"; String password = "datasoft123"; String url = "jdbc:MySQL://localhost/hr"; conn = DriverManager.getConnection (url, userName, password); // Run SQL -> starting time from hither Statement stmt = nada; ResultSet rs = naught; try { stmt = conn.createStatement(); rs = stmt.executeQuery("SELECT first_name, last_name, salary FROM employees WHERE department_id IN (SELECT department_id FROM departments WHERE department_name Similar 'IT%') AND salary > (SELECT avg(salary) FROM employees)"); // Extract data from result set System.out.println ("\n-------------SQL DATA-------------\northward"); while(rs.next()){ //Retrieve by cavalcade proper noun Cord fname = rs.getString("first_name"); String lname = rs.getString("last_name"); int salary = rs.getInt("Salary"); //Display values System.out.print("Name " + fname+' '+lname); System.out.impress(",Salary: " + salary); } System.out.println ("\n\due north-------------Cease-------------\due north"); } catch (SQLException ex){ // handle any errors System.out.println("SQLException: " + ex.getMessage()); System.out.println("SQLState: " + ex.getSQLState()); System.out.println("VendorError: " + ex.getErrorCode()); } finally { if (rs != null) { try { rs.close(); } catch (SQLException sqlEx) { } // ignore rs = null; } if (stmt != goose egg) { endeavour { stmt.close(); } grab (SQLException sqlEx) { } // ignore stmt = null; } } // SQL end at hither } catch (Exception ex) { System.err.println ("Cannot connect to database server"); ex.printStackTrace(); } finally { if (conn != null) { attempt { ///System.out.println("\north***** Allow terminate the Connection *****"); conn.close (); // System.out.println ("\n\nDatabase connexion terminated..."); } take hold of (Exception ex) { System.out.println ("Error in connection termination!"); } } } } } Compile and Run information technology
Assume that 'testsql.java' is stored in E:\ and 'MySQL-connector-java-5.1.31-bin.jar' is stored in "C:\Programme Files\MySQL\MySQL Connector J\".
Note : The class path is the path that the Java Runtime Environment (JRE) searches for classes and other resource files. You can change the class path by using the -classpath or -cp choice of some Java commands when y'all telephone call the JVM or other JDK tools or by using the classpath environment variable.
