#Java mysql jdbc code
This sample code has been written based on the environment and database setup done in the previous chapter.Ĭopy and paste the following example in TestApplication.java, compile and run as follows − This sample example can serve as a template when you need to create your own JDBC application in the future. java -jar Fill in the connection properties and copy the connection string to the clipboard. Either double-click the JAR file or execute the jar file from the command-line.
Open a connection: Requires using the DriverManager.getConnection() method to create a Connection object, which represents a physical connection with the database.Įxecute a query: Requires using an object of type Statement for building and submitting an SQL statement to the database.Įxtract data from result set − Requires that you use the appropriate ResultSet.getXXX() method to retrieve the data from the result set.Ĭlean up the environment − Requires explicitly closing all database resources versus relying on the JVM's garbage collection. MySQL 8.0 1MySQL 8.0 mysql-connector-java-8.0.16.jar .jdbc.Driver MySQL 8. For assistance in constructing the JDBC URL, use the connection string designer built into the MySQL JDBC Driver. JDBC is the standard Java API to connect to traditional relational databases. Most often, using import java.sql.* will suffice. This topic demonstrates creating a sample application that uses Java and JDBC to store and retrieve information in Azure Database for MySQL. Import the packages: Requires that you include the packages containing the JDBC classes needed for database programming. There are certain steps to be followed to connect using JDBC (In this we will connect our Program with MYSQL database). There are following six steps involved in building a JDBC application − Thin Driver: It converts the JDBC method to the vendor-specific database using thin drivers.
#Java mysql jdbc how to
This will show you how to open a database connection, execute a SQL query, and display the results.Īll the steps mentioned in this template example, would be explained in subsequent chapters of this tutorial. in such cases, JDBC throws a SQLException. This chapter provides an example of how to create a simple java based application to access MySQL database. Code language: Java (java) When connecting to MySQL, anything could happens e.g., database server is not available, wrong user name or password, etc.
