In this example, we are discuss about SQL select statement with JDBC batch process.
In this example, we are discuss about SQL select statement with JDBC batch process.In this example, we are discuss about SQL select statement with JDBC batch process. We will create SQL select statement and execute it in a result set and after that fetch this result set and display data on the client screen.
In this example we will used two database tables "user" and "address". First we will insert value in these table and then fetch data by using select statement.
The following code snippet show the process is:
import java.sql.*; public class BatchSelect { static final String driver = "com.mysql.jdbc.Driver"; static final String url = "jdbc:mysql://localhost:3306/"; static final String dbname = "roseindia_jdbc_tutorials"; static final String dbuser = "root"; static final String dbpassword = "root"; public static void main(String[] args) { Connection connection = null; Statement stmt = null; try{ Class.forName(driver); connection = DriverManager.getConnection(url+dbname,dbuser,dbpassword); try{ stmt = connection.createStatement(); connection.setAutoCommit(false); String insertquery1 = "INSERT INTO user (user_id, user_name) VALUES(1,'Brijesh')"; stmt.addBatch(insertquery1); String insertquery2 = "INSERT INTO address (id, address) VALUES(1,'Delhi')"; stmt.addBatch(insertquery2); stmt.executeBatch(); SelectUserdata(stmt); SelectAddressdata(stmt); connection.commit(); } catch (SQLException s){ System.out.println("SQL Exception " + s); } } catch (Exception e){ e.printStackTrace(); } } public static void SelectUserdata(Statement stmt) throws SQLException{ String sql = "SELECT user_id, user_name FROM user"; ResultSet rs = stmt.executeQuery(sql); while(rs.next()){ int user_id = rs.getInt("user_id"); String user_name = rs.getString("user_name"); System.out.print("user_id: " + user_id); System.out.println(" , user_name: " + user_name); } rs.close(); } public static void SelectAddressdata(Statement stmt) throws SQLException{ String sql = "SELECT id, address FROM address"; ResultSet rs = stmt.executeQuery(sql); while(rs.next()){ int address_id = rs.getInt("id"); String address = rs.getString("address"); System.out.print("address_id: " + address_id); System.out.println(" , address: " + address); } rs.close(); } } |
Now we will run this example with the help of eclipse IDE and see the output.
Program output:
The eclipse console output is:
The database table output are:
